Security Fixes

CVE-2012-2678

A flaw was found in the way 389 Directory Server handled password changes. If an LDAP user has changed their password, and the directory server has not been restarted since that change, an attacker able to bind to the directory server could obtain the plain text version of that user's password via the "unhashed#user#password" attribute.

CVE-2012-2746

It was found that when the password for an LDAP user was changed, and audit logging was enabled (it is disabled by default), the new password was written to the audit log in plain text form. This update introduces a new configuration parameter, "nsslapd-auditlog-logging-hide-unhashed-pw", which when set to "on" (the default option), prevents 389 Directory Server from writing plain text passwords to the audit log. This option can be configured in /etc/dirsrv/slapd-ID/dse.ldif.

Security Fix

CVE-2012-0833

A flaw was found in the way the 389 Directory Server daemon (ns-slapd) handled access control instructions (ACIs) using certificate groups. If an LDAP user that had a certificate group defined attempted to bind to the directory server, it would cause ns-slapd to enter an infinite loop and consume an excessive amount of CPU time.

Bug Fixes

BZ#743979

Previously, 389 Directory Server used the Netscape Portable Runtime (NSPR) implementation of the read/write locking mechanism. Consequently, the server sometimes stopped responding to requests under heavy loads. This update replaces the original locking mechanism with the POSIX (Portable Operating System Interface) read/write locking mechanism. The server is now always responsive under heavy loads.

BZ#745201

Previously, Distinguished Names (DNs) were not included in access log records of LDAP compare operations. Consequently, this information was missing in the access logs. This update modifies the underlying source code so that DNs are logged and can be found in the access logs.

BZ#752577

Previously, when 389 Directory Server was under heavy load and operating in a congested network, problems with client connections sometimes occurred. When there was a connection problem while the server was sending Simple Paged Result (SPR) search results to the client, the LDAP server called a cleanup routine incorrectly. Consequently, a memory leak occurred and the server terminated unexpectedly. This update fixes the underlying source code to ensure that cleanup tasks are run correctly and no memory leaks occur. As a result, the server does not terminate or become unresponsive under heavy loads while servicing SPR requests.

BZ#757897

Previously, certain operations with the Change Sequence Number (CSN) were not performed efficiently by the server. Consequently, the ns-slapd daemon consumed up to 100% of CPU time when performing a large number of CSN operations during content replication. With this update, the underlying source code has been modified to perform the CSN operations efficiently. As a result, large numbers of CSN operations can be performed during content replications without any performance issues.

BZ#757898

Previously, allocated memory was not correctly released in the underlying code for the SASL GSSAPI authentication method when checking the Simple Authentication and Security Layer (SASL) identity mappings. This problem could cause memory leaks when processing SASL bind requests, which eventually caused the LDAP server to terminate unexpectedly with a segmentation fault. This update adds function calls that are needed to free allocated memory correctly. Memory leaks no longer occur and the LDAP server no longer crashes in this scenario.

BZ#759301

Previously, 389 Directory Server did not handle the Entry USN (Update Sequence Number) index correctly. Consequently, the index sometimes became out of sync with the main database and search operations on USN entries returned incorrect results. This update modifies the underlying source code of the Entry USN plug-in. As a result, the Entry USN index is now handled by the server correctly.

BZ#772777

Previously, search filter attributes were normalized and substring regular expressions were compiled repeatedly for every entry in the search result set. Consequently, using search filters with many attributes and substring subfilters resulted in poor search performance. This update ensures that search filters are pre-compiled and pre-normalized before being applied. These changes result in better search performance when applying search filters with many attributes and substring subfilters.

BZ#772778

Previously, the number of ACIs (Access Control Information records) to be cached was limited to 200. Consequently, evaluating a Directory Server entry against more than 200 ACIs failed with the following error message:

acl_TestRights - cache overflown

This update increases the default ACI cache limit to 2000 and allows it to be configurable by means of the new parameter nsslapd-aclpb-max-selected-acls in the configuration file entry "cn=ACL Plugin,cn=plugins,cn=config". As a result, the aforementioned error message is not displayed unless the new limit is exceeded, and it is now possible to change the limit when needed.

BZ#772779

Previously, the restore command contained a code path leading to an infinite loop. Consequently, 389 Directory Server sometimes became unresponsive when performing a restore from a database backup. This update removes the infinite loop code path from the underlying source code. As a result, the server does not stop responding when performing a database restore.

BZ#781485

Previously, performing the ldapmodify operation to modify RUV (Replica Update Vector) entries was allowed. Consequently, 389 Directory Server became unresponsive when performing such operations. This update disallows direct modification of RUV entries. As a result, the server does not stop responding when performing such operations, and returns an error message advising usage of the CLEANRUV operation instead.

BZ#781495

Previously, to identify restart events of 389 Directory Server, the logconv.pl script searched server logs for the "conn=0 fd=" string. Consequently, the script reported a wrong number of server restarts. This update modifies the script to search for the "conn=1 fd=" string instead. As a result, the correct number of server restarts is now returned.

BZ#781500

When reloading a database from an LDIF (LDAP Data Interchange Format) file that contained an RUV element with an obsolete or decommissioned replication master, the changelog was invalidated. As a consequence, 389 Directory Server emitted error messages and required re-initialization. This update ensures that the user is properly informed about obsolete or decommissioned replication masters, and that such masters are deleted from the RUV entries. Database is now reloaded as expected in this scenario.

BZ#781516

Previously, when a non-leaf node became a tombstone entry, its child entries lost the parent-child relationships. Consequently, non-leaf tombstone entries could have been reaped prior to their child tombstone entries. This update fixes the underlying source code so that parent-child relationships are maintained even when a non-leaf entry is deleted. As a result, tombstones are now reaped correctly in the bottom-up order.

BZ#781529

Previously, no validation of managed entry attributes against the managed entry template was performed before updating 389 Directory Server's managed entries. Consequently, managed entries could have been updated after updating an original entry attribute that was not contained in the managed entry template. This update adds a check that compares modified attributes with managed entry template attributes. As a result, the managed entries are not updated unless the modified attributes of the original entry are contained in the managed entry template.

BZ#781533

Previously, 389 Directory Server did not shut down before all running tasks had been completed. Consequently, it sometimes took a long time for the Directory Server to shut down when a long-running task was being carried out. This update enhances the underlying source code with a check for server shutdown requests during performance of long-running tasks. As a result, the server shuts down in a standard amount of time even when a long-running task is being processed.

BZ#781537

Previously, 389 Directory Server expected the value of the authzid attribute to be fully BER (Basic Encoding Rules) encoded. Consequently, the following error was returned when performing the ldapsearch command with proxy authorization:

unable to parse proxied authorization control (2 (protocol error))

This update modifies the underlying source code so that full BER encoding of the provided authzid value is not required. As a consequence, no error is returned in the scenario described above.

BZ#781538

Previously, the buffer for matching rule OIDs (Object Identifiers) had a fixed size of 1024 characters. Consequently, matching rule OIDs got truncated when their total length exceeded 1024 characters. This update modifies the underlying source code to use a dynamically allocated buffer instead of the one with a fixed size. As a result, any number of matching rule OIDs can be handled without being truncated.

BZ#781539

Previously, executing the ldapsearch command on the "cn=config" object returned all attributes of the object, including attributes with empty values. This update ensures that attributes with empty values are not saved into "cn=config", and enhances the ldapsearch command with a check for empty attributes. As a result, only attributes that have a value are returned in the aforementioned scenario.

BZ#781541

Previously, log records of operations performed using a proxy user contained the main user as the one who performed the operation. This update ensures that the proxy user is logged in log records of the search, add, mod, del, and modrdn operations.

BZ#784343

Previously, the database upgrade scripts checked if the server was offline by checking for the presence of .pid files. In some cases, however, the files remain present even if the associated processes have already been terminated. Consequently, the upgrade scripts sometimes assumed that the Directory Server was online and did not proceed with the database upgrade even if the server was actually offline. This update adds an explicit test to check if the processes referenced in the .pid files are really running. As a result, the upgrade scripts now work as expected.

BZ#784344

Previously, the repl-monitor command used only the subdomain part of hostnames for host identification. Consequently, hostnames with the identical subdomain part (for example: "ldap.domain1", "ldap.domain2") were identified as a single host, and inaccurate output was produced. This update ensures that the entire hostname is used for host identification. As a result, all hostnames are identified as separate and output of the repl-monitor command is accurate.

BZ#788140

Previously, the server used unnormalized DN strings to perform internal search and modify operations while the code for modify operations expected normalized DN strings. Consequently, error messages like the following one were logged when performing replication with domain names specified in unnormalized format:

NSMMReplicationPlugin - repl_set_mtn_referrals: could not set referrals for 
replica dc=example,dc=com: 32

This update ensures that DN strings are normalized before being used in modify operations. As a result, replication does not produce the error messages in the aforementioned scenario.

BZ#788722

Previously, the 389-ds-base/ldap/servers/snmp/ directory contained .mib files without copyright headers. Consequently, the files could not be included in certain Linux distributions due to copyright reasons. This update merges information from all such files into the redhat-directory.mib file, which contains the required copyright information, and ensures that it is the only file in the directory. As a result, no copyright issues block 389 Directory Server from being included in any Linux distribution.

BZ#788724

Previously, the underlying source code for extensible search filters used strcmp routines for value comparison. Consequently, using extensible search filters with binary data returned incorrect results. This update modifies the underlying source code to use binary-aware functions. As a result, extensible search filters work with binary data correctly.

BZ#788725

Previously, value normalization of the search filter did not respect the used filter type and matching rules. Consequently, when using different values than the default comparison type for the searched attribute syntax, search attempts returned incorrect results. This update modifies the underlying source code to use normalization sensitive to matching rules on filter attributes and values. As a result, search results in accordance with the matching rules are returned.

BZ#788729

Previously on the Directory Server, tombstones of child entries in a database were handled incorrectly. Therefore, if the database contained deleted entries that were converted to tombstones, an attempt to reindex the entryrdn index failed with the following error message:

_entryrdn_insert_key: Getting "nsuniqueid=ca681083-69f011e0-8115a0d5-f42e0a24,ou=People,dc=example,dc=com" failed

With this update, 389 Directory Server handles tombstones of child entries correctly, and the entryrdn index can now be reindexed successfully with no errors.

BZ#788731

Previously, RUV tombstone entries were indexed incorrectly by the entryrdn index. Consequently, attempts to search for such entries were not successful. This update ensures correct indexing of RUV tombstone entries in the entryrdn index and search attempts for such entries are now successful.

BZ#788741

Previously, the DNA (Distributed Numeric Assignment) plug-in used too short timeout for requests to replicate a range of UIDs. Consequently, using replication with DNA to add users sometimes failed on networks with high latency, returning the following error message:

Operations error: Allocation of a new value for range cn=posix ids,cn=distributed 
numeric assignment plugin,cn=plugins,cn=config failed

With this update, the default timeout for such replication requests has been set to 10 minutes. As a result, no errors are returned when using replication with DNA to add users, and the operation succeeds.

BZ#788745

Previously, change sequence numbers (CSNs) in RUV were not refreshed when a replication role was changed. Consequently, data on the server became inconsistent. This update ensures that CSNs are refreshed when a replication role is changed. As a result, data inconsistency is no longer observed in the previously mentioned cases.

BZ#788749

Previously, errors in schema files were not reported clearly in log files. Consequently, the messages could be incorrectly interpreted as reporting an error in the dse.ldif file. This update modifies the error messages so that they include the name of and path to the file where the error was found.

BZ#788750

Previously, the server used an outdated version of the nisDomain schema after an upgrade. Consequently, restarting 389 Directory Server after an upgrade produced the following error message:

attr_syntax_create - Error: the EQUALITY matching rule [caseIgnoreMatch] is not 
compatible with the syntax [1.3.6.1.4.1.1466.115.121.1.26] for the attribute [nisDomain]

This update ensures that the server uses the latest version of the nisDomain schema. As a result, restarting the server after an upgrade does not show any errors.

BZ#788751

389 Directory Server previously did not properly release allocated memory after finishing normalization operations. This caused memory leaks to occur during server's runtime. This update fixes the underlying code to release allocated memory properly so that memory leaks no longer occur under these circumstances

BZ#788753

Previously, the "connection" attribute was not included in the cn=monitor schema, which caused the access control information (ACI) handling code to ignore the ACI. Consequently, requesting the connection attribute when performing anonymous search on cn=monitor returned the connection attribute, even though it was denied by the default ACI. This update ensures that the ACI is processed even if the attribute is not in the schema. As a result, the connection attribute is not displayed if the ACI denies it.

BZ#788754

Previously, several memory leak errors sometimes occurred during the server's runtime. This update fixes all the memory leak errors so that none of them occur anymore.

BZ#788755

Previously, IPv4-mapped IPv6 addresses were treated as independent addresses by 389 Directory Server. Consequently, errors were reported during server startup when such addresses conflicted with standard IPv4 addresses. This update ensures that the IPv4 part of every IPv4-mapped IPv6 address is compared with existing IPv4 addresses. As a result, the server starts with no errors even when IPv4-mapped IPv6 addresses conflict with standard IPv4 addresses.

BZ#788756

Previously, the 389-ds-base man pages contained several typos and factual errors. This update corrects the man pages so that they contain correct information and no typos.

BZ#790491

Previously, a NULL pointer dereference sometimes occurred when initializing a Directory Server replica. Consequently, the server terminated unexpectedly with a segmentation fault. This update enhances the underlying source code for replica initialization with a check for the NULL value. As a result, replica initialization always finishes successfully.

BZ#796770

Previously, a double free error sometimes occurred during operations with orphaned tombstone entries. Consequently, when an orphaned tombstone entry was passed to the tombstone_to_glue function, the Directory Server terminated unexpectedly. This update fixes the logic for getting ancestor tombstone entries and eliminates the chance to convert a tombstone entry into an orphaned entry. As a result, unexpected server termination no longer occurs in the aforementioned scenario.

BZ#800215

Previously, an internal loop was incorrectly handled in code of the ldapcompare command. Consequently, performing concurrent comparison operations on virtual attributes caused the Directory Server to become unresponsive. This update fixes the internal loop issue. As a result, the server performs concurrent comparison operations without any issues.

BZ#803930

Previously, when upgrading 389 Directory Server, server startup had been initiated before the actual upgrade procedure finished. Consequently, the startup failed with the following error message:

ldif2dbm - _get_and_add_parent_rdns: Failed to convert DN cn=TESTRELM.COM to RDN

This update ensures that the server does not start before the upgrade procedure finishes. As a result, the server boots up successfully after the upgrade.

BZ#811291

Previously, the code of the range read operation did not correctly handle situations when an entry was deleted while a ranged search operation was being performed. Consequently, performing delete and ranged search operations concurrently under heavy loads caused the Directory Server to terminate unexpectedly. This update fixes the underlying source code to handle such situations correctly. As a result, the server does not terminate before performing delete and ranged search operations concurrently under heavy loads.

BZ#813964

When performing delete and search operations against 389 Directory Server under high load, the DB_MULTIPLE_NEXT pointer to the stack buffer could have been set to an invalid value. As a consequence, pointer's dereference lead to an attempt to access memory that was not allocated for the stack buffer. This caused the server to terminate unexpectedly with a segmentation fault. With this update, the DB_MULTIPLE_NEXT pointer is now properly tested. If the pointer's value is invalid, the page or value is considered deleted and the stack buffer is reloaded. As a result, the segmentation fault no longer occurs in this scenario.

BZ#815991

The ldap_initialize() function is not thread-safe. Consequently, 389 Directory Server terminated unexpectedly during startup when using replication with many replication agreements. This update ensures that calls of the ldap_initialize() function are protected by a mutual exclusion. As a result, when using replication with many replication agreements, the server starts up correctly.

BZ#819643

Due to an error in the underlying source code, an attempt to rename an RDN (Relative Distinguished Name) string failed if the new string sequence was the same except of using the different lower/upper case of some letters. This update fixes the code so that it is possible to rename RDNs to the same string sequence with case difference.

BZ#821542

Previously, the letter case information was ignored when renaming DN strings. Consequently, if the new string sequence differed only in the case of some letters, a DN string was only converted to lowercase and the case information lost. This update modifies the underlying code so that it is now possible to rename RDNs to the same string sequence with case difference.

BZ#822700

Previously, the code for ACI handling did not reject incorrectly specified DNs. Consequently, incorrectly specified DNs in an ACI caused 389 Directory Server to terminate unexpectedly during startup or after an online import. This update ensures that the underlying source code for ACI handling rejects incorrectly specified DNs. As a result, the server does not terminate in this scenario.

BZ#824014

Previously, the code handling the “entryusn” attribute modified cache entries directly. Consequently under heavy loads, the server terminated unexpectedly when performing delete and search operations using the “entryusn” and “memberof” attributes with referential integrity enabled. This update ensures that the entries are never modified in the cache directly. As a result, the server performs searches in the previously described conditions without terminating unexpectedly.

Enhancements

BZ#683241

Previously, post-operation plug-ins were executed after initial operation results had been returned to the LDAP client. Consequently, some results of the initial operation might not have been immediately available. This update introduces the "betxnpreoperation" and "betxnpostoperation" plug-in types. Plug-ins of these types run inside the regular transaction of initial operations. As a result, when these plug-in types are used, operations triggered by the initial operation complete before completion of the initial operation.

BZ#766322

Previously, there was no easy way to determine what default search base an LDAP client should use. Consequently, LDAP clients with no search base configured attempted to search against 389 Directory Server. This update adds a new attribute, defaultNamingContext, to the root DSE (Directory Server Entry). As a result, clients can query the root DSE for the value of the defaultNamingContext attribute and use the returned value as a search base.

BZ#768086

This update introduces the nsslapd-minssf-exclude-rootdse configuration attribute, with possible values "on" and "off". If its value is "off", which is the default, the server allows clients to access the root DSE even if the Security Strenght Factor (SSF) value is less than the nsslapd-minssf attribute value. As a result, it is possible to allow access to the root DSE without using SSL/TLS even if the rest of the server requires SSL/TLS.

BZ#768091

Previously, the delete operation was not allowed for Managed Entry Config entries. Consequently, attempts to delete such entries were rejected with the following error message:

ldap_delete: Server is unwilling to perform (53)
additional info: Not a valid operation.

This update modifies the underlying source code so that deletion of Managed Entry Config entries is allowed and can be performed successfully.

BZ#781501

Previously, extended user account information was not available to LDAP clients from 389 Directory Server. This update adds support for Account Usable Request Control, which enables LDAP clients to get the extended user account information.

BZ#788760

Previously, the logconv.pl script was only able to produce a summary of operations for a file or for a requested period. This update introduces the -m option for generation of per-second statistics, and the -M option for generation of per-minute statistics. The statistics are generated in CSV format suitable for further post-processing.

BZ#790433

Previously, all newly created entries had to be added to groups manually. This update adds a new plug-in which ensures automatic adding of each new entry to a group if it matches certain criteria.

Security Fixes

CVE-2012-1106

If the C handler plug-in in ABRT was enabled (the abrt-addon-ccpp package installed and the abrt-ccpp service running), and the sysctl fs.suid_dumpable option was set to "2" (it is "0" by default), core dumps of set user ID (setuid) programs were created with insecure group ID permissions. This could allow local, unprivileged users to obtain sensitive information from the core dump files of setuid processes they would otherwise not be able to access.

CVE-2011-4088

ABRT did not allow users to easily search the collected crash information for sensitive data prior to submitting it. This could lead to users unintentionally exposing sensitive information via the submitted crash reports. This update adds functionality to search across all the collected data. Note that this fix does not apply to the default configuration, where reports are sent to Red Hat Customer Support. It only takes effect for users sending information to Red Hat Bugzilla.

Bug Fixes

BZ#809587, BZ#745976

When the ABRT GUI was used to report a bug using the menu button Report problem with ABRT, an empty bug was created. This update removes this button as it was only used for testing purposes.

BZ#800828

When a new dump directory was saved to /var/spool/abrt-upload/ via the reporter-upload utility, the ABRT daemon copied the dump directory to /var/spool/abrt/ and incremented the crash count which was already incremented before. Due to the crash count being incremented twice, the dump directory was marked as a duplicate of itself and removed. With this update, the crash count is no longer incremented for remotely uploaded dump directories, thus fixing the issue.

BZ#747624

The /usr/bin/abrt-cli utility was missing a man page. This update adds the abrt-cli(1) man page.

BZ#796216

Analyzing lines of a kernel oops caused the line variable to be freed twice. This update fixes this bug, and kernel oopses are now properly analyzed.

BZ#770357

Prior to this update, ABRT email notification via the mailx plug-in did not function properly due to a missing default configuration file for the mailx plug-in. This update adds a default configuration file for the mailx plug-in: /etc/libreport/plugins/mailx.conf.

BZ#799352

Starting the ABRT daemon resulted in an error if dbus was not installed on the system. This update removes the dbus dependency and the ABRT daemon can now be started even if dbus is not installed on the system.

BZ#727494

The previous version of ABRT silently allowed users to report the same problem to Bugzilla multiple times. This behavior is now changed and users are warned if the report was already submitted. The max allowed size of email attachments and local logs was increased to 1 MB. This fixes the problem where longer reports were being lost when sent via email or stored locally using the logger plug-in.

BZ#746727

This update fixes a bug which caused the /tmp/anaconda-tb-* files to be sometimes recognized as a binary file and sometimes as a text file.

BZ#771597

ABRT 2.x has added various new daemons. However, not all of the added daemons were properly enabled during the transition from ABRT 1.x. With this update, all daemons are correctly started and updating from ABRT 1.x to ABRT 2.x works as expected.

BZ#751068

The abrt-cli package previously depended on the abrt-addon-python package. This prevented users from removing the abrt-addon-python package via Yum as the abrt-cli would be removed as well. With this update, a new “virtual” abrt-tui package has been added that pulls all the required packages in order to use ABRT on the command line, thus, resolving the aforementioned issue.

BZ#749100

Previously, some strings in the ABRT tools were not marked as translatable. This update fixes this issue.

BZ#773242

When ABRT attempted to move data, a misleading message was returned to the user informing that a copy of the dump was created. This update improves this message so that it is clear that ABRT does not copy data but moves it.

BZ#811147

When a backtrace contains a frame with text consisting of function arguments that was too long, the backtrace printer in GDB truncates the arguments. The backtrace parser could not handle the truncated arguments and did not format them properly. With this update, the backtrace parser detects the truncated strings, indicating the function arguments were truncated. The parser state then adapts to this situation and correctly parses the backtrace.

BZ#823411

A change in the Bugzilla API prevented the ABRT bugzilla plug-in from working correctly. This update resolves this issue by modifying the source code to work with the new Bugzilla API.

BZ#758366

This update fixes a typographical error in the commentary of various ABRT configuration files.

BZ#625485

The previous version of ABRT generated an invalid XML log file. This update fixes this and every non-ASCII character is now escaped.

BZ#788577

Unlike ABRT, python-meh was not including a list of environment variables in its problem reports. A list of environment variables is useful information for assignees of the created bug. With this update, code producing a list of environment variables and passing it to libreport was added to python-meh, and problem reports generated by python-meh now include lists of environment variables.

BZ#674199

Prior to this update, the alsactl tool tried to initialize all sound cards if the /etc/asound.state file was not present. As a consequence, SElinux could deny access to non-existent devices. This update modifies the underlying code so that alsactl is called only once from udev.

BZ#650113

With this update, the alsa-delay and alsaloop utilities have been added to alsa-utils to manage the system audio delay.

Bug Fixes

BZ#690058

Prior to this update, the noprobe argument in a kickstart file was not passed to the last known codepath. Consequently, the noprobe request was not properly honored by Anaconda. This update improves the code so that the argument is passed to the last known codepath. As a result, device drivers are loaded according to the device command in the kickstart file.

BZ#691794

Previously, an improper device file that provided access to an array as a whole was used to initialize the boot loader in a Device Mapper Multipath (DM-Multipath) environment. Consequently, the system was not bootable. Anaconda has been modified to enumerate all drives in an array and initialize the boot loader on each of them. As a result, the system now boots as expected.

BZ#723404

When performing a minimal installation from media without the use of a network, network devices did not have a working default network configuration. Consequently, bringing a network device up after reboot using the ifup command failed. This update sets the value of BOOTPROTO to dhcp in default network device configuration files. As a result, network devices can be activated successfully using the ifup command after reboot in the scenario described.

BZ#727136

When Anaconda places a PowerPC Reference Platform (PReP) boot partition on a different drive to the root partition, the system cannot boot. This update forces the PReP boot partition to be on the same drive as the root partition. As a result, the system boots as expected.

BZ#734128

Due to a regression, when installing on systems with pre-existing mirrored Logical Volumes (LV), the installer failed to properly detect the Logical Volume Management configuration containing mirrored logical volumes. Consequently, a mirrored logical volume created before installation was not shown and could not be used in kickstart. The code to handle mirrored logical volumes has been updated to make use of the udev information that changed due to a previous bug fix. As a result, mirrored logical volumes are correctly detected by the installer.

BZ#736457

On IBM System z architectures, z/VM guests with only one CPU allocated failed to read the Conversational Monitor System (CMS) configuration file used by the installation environment. Consequently, users of z/VM guests with a single CPU had to either pass all installation environment configuration values on the kernel boot line or supply the information at the interactive prompts as the installation environment booted up. This update improves the code to detect the number of guests after mounting the /proc file. As a result, guests with one CPU can bring the boot device online so the CMS configuration file can be read and automated installations proceed as expected.

BZ#738577

The repo commands in kickstart generated by Anaconda contained base installation repository information but they should contain only additional repositories added either by the repo kickstart command or in the graphical user interface (GUI). Consequently, in media installations, the repo command generated for installation caused a failure when the kickstart file was used. With this update, Anaconda now generates repo commands only for additional repositories. As a result, kickstart will not fail for media installations.

BZ#740870

Manual installation on to BIOS RAID devices of level 0 or level 1 produced an Intel Media Storage Manager (IMSM) metadata read error in the installer. Consequently, users were not able to install to such devices. With this update, Anaconda properly detects BIOS RAID level 0 and level 1 IMSM metadata. As a result, users are able to install to these devices.

BZ#746495

The LiveCD environment was missing a legacy symlink to the devkit-disks utility. Consequently, the call that modified automounter behavior was never properly executed. The code has been updated to call the proper non-legacy binary. As a result, USB devices used during installation are no longer automounted.

BZ#747219

The console tty1 was put under control of Anaconda, but was not returned when Anaconda exited. Consequently, init did not have permission to modify tty1's settings to enable Ctrl+C functionality when Anaconda exited, which resulted in Ctrl+C not working when the installer prompted the user to press the Ctrl+C or Ctrl+Alt+Delete key combination after Anaconda terminated unexpectedly. A code returning tty1 control back to init was added to Anaconda. As a result, Ctrl+C now works as expected if the user is prompted to press it when Anaconda crashes.

BZ#750126

The Bash version used in the buildinstall script had a bug that influenced parsing of the =~ operator. This operator is used to check for the architecture when including files. Consequently, some binaries which provide the grub command were present on x86_64 versions of the installer, but were missing from i686 media. The Bash code has been modified to prevent this bug. As a result, the binaries are now also present on i686 media and users can now use the grub command from installation media as expected.

BZ#750417

Due to bad ordering in the unmounting sequence, the dynamic linker failed to link libraries, which caused the mdadm utility not to work and exit with the status code of 127. This update fixes the ordering in the unmounting sequence and as a result, the dynamic linker and mdadm now work correctly.

BZ#750710

There was no check to see if the file descriptors passed as stdout and stderr were distinct. Consequently, if the stdout and stderr descriptors were the same, using them both for writing resulted in overwriting and the log file not containing all of the lines expected. With this update, if the stdout and stderr descriptors are the same then only one of them is used for both stdin and stderr. As a result, the log file contains all lines from both stdout and stderr.

BZ#753108

When installing on a system with more than one disk with a PowerPC Reference Platform (PReP) partition present, the PReP partitions that should be left untouched were updated. This update corrects the problem so that PReP partitions other than the one used during installation are left untouched. As a result, old PReP partitions do not get updated.

BZ#754031

The kernel command line /proc/cmdline ends with \n but the installer only checked for \0. Consequently, the devel argument was not detected when it was the last argument on the command line and the installation failed. This update improves the code to also check for \n. As a result, the devel argument is correctly parsed and installation proceeds as expected.

BZ#756608

Network installations on IBM System z check the nameserver address provided using the ping command. Environments restricting ICMP ECHO packets will cause this test to fail, halting the installation and asking the user whether or not the provided nameserver address is valid. Consequently, automated installations using kickstart will stop if this test fails. With this update, in the event that the ping test fails, the nslookup command is used to validate the provided nameserver address. If the nslookup test succeeds then kickstart will continue with the installation. As a result, automated network installations on IBM System z in non-interactive mode will complete as expected in the scenario described.

BZ#760250

When configuring a system with multiple active network interfaces and the ksdevice = link command was present, the link specification was not used consistently for device activation and device configuration. Consequently, other network devices having link status were sometimes misconfigured using the settings targeted to the device activated by the installer. With this update, the code has been improved and now refers to the same device with link specification both in case of device activation and device configuration. As a result, when multiple devices with link status are present during installation, ksdevice = link specification of the device to be activated and used by the installer does not cause misconfiguration of another device having link status.

BZ#766902

When configuring the network using the Anaconda GUI hostname screen, the keyboard shortcut for the Configure Network button was missing. This update adds the C keyboard shortcut. Network configuration can now be invoked using the Alt+C keyboard shortcut.

BZ#767727

The Ext2FS class in Anaconda has a maximum file size attribute correctly set to 8 TB, but Ext3FS and Ext4FS inherited this value without overriding it. Consequently, when attempting to create an ext3 or ext4 file system of a size greater than 8Tb the installer would not allow it. With this update, the installer's upper bound for new ext3 and ext4 filesystem size has been adjusted from 8Tb to 16TB. As a result, the installer now allows creation of ext3 and ext4 filesystems up to 16TB.

BZ#769145

The Anaconda dhcptimeout boot option was not working. NetworkManager used a DHCP transaction timeout of 45 seconds without the possibility of configuring a different value. Consequently, in certain cases NetworkManager failed to obtain a network address. NetworkManager has been extended to read the timeout parameter from a DHCP configuration file and use that instead of the default value. Anaconda has been updated to write out the dhcptimeout value to the interface configuration file used for installation. As a result, the boot option dhcptimeout works and NetworkManager now waits to obtain an address for the duration of the DHCP transaction period as specified in the DHCP client configuration file.

BZ#783245

Prior to this update, USB3 modules were not in the Anaconda install image. Consequently, USB3 devices were not detected by Anaconda during installation. This update adds the USB3 modules to the install image and USB3 devices are now detected during installation.

BZ#783841

When the kickstart clearpart command or the installer's automatic partitioning options to clear old data from the system's disks were used with complex storage devices such as logical volumes and software RAID, LVM tools caused the installation process to become unresponsive due to a deadlock. Consequently, the installer failed when trying to remove old metadata from complex storage devices. This update changes the LVM commands in the udev rules packaged with the installer to use a less restrictive method of locking and the installer was changed to explicitly remove partitions from a disk instead of simply creating a new partition table on top of the old contents when it initializes a disk. As a result, LVM no longer hangs in the scenario described.

BZ#785400

The /usr/lib/anaconda/textw/netconfig_text.py file tried to import a module from the wrong location. Consequently, Anaconda failed to start and the following error message was generated:

No module named textw.netconfig_text

The code has been corrected and the error no longer occurs in the scenario described.

BZ#788537

Prior to this update, kickstart repository entries did not use the global proxy setting. Consequently, on networks restricted to use a proxy installation would terminate unexpectedly when attempting to connect to additional repository entries in a kickstart file if no proxy had been explicitly specified. This update changes the code to use the global proxy if an additional repository has no proxy set for it. As a result, the global proxy setting will be used and installation will proceed as expected in the scenario described.

BZ#800388

The kickstart pre and post installation scripts had no information about the proxy being used by Anaconda. As a consequence, programs such as wget and curl would not work properly in a pre-installation and post-installation script on networks restricted to using a proxy. This update sets the PROXY, PROXY_USER, PROXY_PASSWORD environmental variables. As a result, pre and post installation scripts now have access to the proxy setting used by Anaconda.

BZ#802397

Using the --onbiosdisk=NUMBER option for the kickstart part command sometimes caused installation failures as Anaconda was not able to find the disk that matches the specified BIOS disk number. Users wishing to use BIOS disk numbering to control kickstart installations were not able to successfully install Red Hat Enterprise Linux. This update adjusts the comparison in Anaconda that matches the BIOS disk number to determine the Linux device name. As a result, users wishing to use BIOS disk numbering to control kickstart installations will now be able to successfully install Red Hat Enterprise Linux.

BZ#805910

Due to a regression, when running the system in Rescue mode with no or only uninitialized disks, the Anaconda storage subsystem did not check for the presence of a GUI before presenting the user with a list of options. Consequently, when the user selected continue the installer terminated unexpectedly with a traceback. This update adds a check for presence of the GUI and falls back to a TUI if there is none. As a result, the user is informed about the lack of usable disks in the scenario described.

BZ#823810

When using Anaconda with Qlogic qla4xxx devices in firmware boot mode and with iSCSI targets set up in BIOS (either enabled or disabled), the devices were exposed as iSCSI devices. But in this mode the devices cannot be handled with the iscsiadm and libiscsi tools used by the installer. Consequently, installation failed with a traceback during examination of storage devices by the installer. This update changes the installer to not try to manage iSCSI devices set up with qla4xxx firmware with iscsiadm or libiscsi. As a result, installation in an environment with iSCSI targets set up by qla4xxx devices in firmware mode finishes successfully.

Note

The firmware boot mode is turned on and off by the qla4xxx.ql4xdisablesysfsboot boot option. With this update, it is enabled by default.

Enhancements

BZ#500273

There was no support for binding of iSCSI connections to network interfaces, which is required for installations using multiple iSCSI connections to a target on a single subnet for Device Mapper Multipath (DM-Multipath) connectivity. Consequently, DM-Multipath connectivity could not be used on a single subnet as all devices used the default network interface. With this update, the Bind targets to network interfaces option has been added to the “Advanced Storage Options” dialog box. When turned on, targets discovered specifically for all active network interfaces are available for selection and login. For kickstart installations a new iscsi --iface option can be used to specify network interface to which a target should be bound. Once interface binding is used, all iSCSI connections have to be bound, that is to say the --iface option has to be specified for all iscsi commands in kickstart. Network devices required for iSCSI connections can be activated either using kickstart network command with the --activate option or in the graphical user interface (GUI) using the Configure Network button from the “Advanced Storage Options” dialog (“Connect Automatically” has to be checked when configuring the device so that the device is also activated in the installer). As a result, it is now possible to configure and use DM-Multipath connectivity for iSCSI devices using different network interfaces on a single subnet during installation.

BZ#625697

The curl command line tool was not in the install image file. Consequently, curl could not be used in the %pre section of kickstart. This update adds curl to the install image and curl can be used in the %pre section of kickstart.

BZ#660686

Support for installation using IP over InfiniBand (IPoIB) interfaces has been added. As a result, it is possible to install systems connected directly to an InfiniBand network using IPoIB network interfaces.

BZ#663647

Two new options were added to the kickstart volgroup command to specify initially unused space in megabytes or as a percentage of the total volume group size. These options are only valid for volume groups being created during installation. As a result, users can effectively reserve space in a new volume group for snapshots while still using the --grow option for logical volumes within the same volume group.

BZ#671230

The GPT disk label is now used for disks of size 2.2 TB and larger. As a result, Anaconda now allows installation to disks of size 2.2 TB and larger, but the installed system will not always boot properly on non-EFI systems. Disks of size 2.2 TB and larger may be used during the installation process, but only as data disks; they should not be used as bootable disks.

BZ#705328

When an interface configuration file is created by a configuration application such as Anaconda, NetworkManager generates the Universally Unique IDentifier (UUID) by hashing the existing configuration file name. Consequently, the same UUID was generated on multiple installed systems for a given network device name. With this update, a random UUID is generated by Anaconda for NetworkManager so that it does not have to generate the connection UUID by hashing the configuration file name. As a result, each network connection of all installed systems has different UUID.

BZ#735791

When IPv6 support is set to be disabled by the installer using the noipv6 boot option, or the network --nopipv6 kickstart command, or by using the “Configure TCP/IP” screen of the loader Text User Interface (TUI), and no network device is configured for IPv6 during installation, the IPv6 kernel modules on the installed system will now be disabled.

BZ#735857

The ability to configure a VLAN discovery option for Fibre Channel over Ethernet (FCoE) devices added during installation using Anaconda's graphical user interface was required. All FCoE devices created in Anaconda installer were configured to perform VLAN discovery using the fcoemon daemon by setting the AUTO_VLAN value of its configuration file to yes. A new “Use auto vlan” checkbox was added to the “Advanced Storage Options” dialog, which is invoked by the Add Advanced Target button in “Advanced Storage Devices” screen. As a result, when adding FCoE device in Anaconda, it is now possible to configure the VLAN discovery option of the device using “Use auto vlan” checkbox in “Advanced Storage Options” dialog. The value of AUTO_VLAN option of FCoE device configuration file /etc/fcoe/cfg-device is set accordingly.

BZ#737097

The lsscsi and sg3_utils were not present in the install image. Consequently, maintenance of Data Integrity Field (DIF) disks was not possible. This update adds the lsscsi and sg3_utils to the install image and now utilities to maintain DIF disks can be used during the installation.

BZ#743784

Anaconda creates FCoE configuration files under the /etc/fcoe/ directory using biosdevname, which is the new style interface naming scheme, for all the available Ethernet interfaces for FCoE BFS. However, it did not add the ifname kernel command line argument for FCoE interface that stays offline after discovering FCoE targets during installation. Because of this, during subsequent reboot the system tried to find the old style ethX interface name in /etc/fcoe/, which does not match the file created by Anaconda using biosdevname. Therefore, due to the missing FCoE config file, FCoE interface is never created on this interface. Consequently, during FCoE BFS installation, when an Ethernet interface went offline after discovering the targets, FCoE links did not come up after reboot. This update adds dracut ip parameters for all FCoE interfaces including those that went offline during installation. As a result, FCoE interfaces disconnected during installation will be activated after reboot.

BZ#744129

Installations with the swap --recommended command in kickstart created a swap file of size 2 GB plus the installed RAM size regardless of the amount of RAM installed. Consequently, machines with a large amount of RAM had huge swap files prolonging the time before the oom_kill syscall was invoked even in malfunctioning cases. In this update, swap size calculations for swap --recommended were changed to meet the values recommended in the documentation https://access.redhat.com/knowledge/solutions/15244 and the --same-as-ram option was added for the swap kickstart command and as the default in GUI/TUI installations. As a result, machines with a lot of RAM have a reasonable swap size now if swap --recommended is used. However, hibernation might not work with this configuration. If users want to use hibernation they should use swap --same-as-ram.

BZ#755147

If there are multiple Ethernet interfaces configured for FCoE boot, by default, only the primary interface is turned on and the other interfaces are not configured. This update sets the value ONBOOT=yes in the ifcfg configuration file during installation for all network interfaces used by FCoE. As a result, all network devices used for installation to FCoE storage devices are activated automatically after reboot.

BZ#770486

This update adds the Netcat (nc) networking utility to the install environment. Users can now use the nc program in Rescue mode.

BZ#773545

The virt-what shell script has been added to the install image. Users can now use the virt-what tool in kickstart.

BZ#784327

Firmware files were loaded only from RPM files in $prefix/lib/firmware paths on a Driver Update Disk (DUD). This update adds the $prefix/lib/firmware/updates directory to the path to be searched for firmware. RPM files containing firmware updates can now have firmware files in %prefix/lib/firmware/updates.

BZ#723350

Previously, binary files from the base atlas package contained illegal instructions from an incompatible instruction set (3DNow!). As a consequence, an "Illegal instruction" error was displayed. This update disables usage of the instruction set.

Bug Fixes

BZ#803349

Previously, not enough information was parsed to determine whether audit records are part of the same event if the server's node name was longer than approximately 80 characters. With this update, the problem has been fixed.

BZ#797848

This update fixes a typo in the audit.rules(7) man page.

BZ#658630

Prior to this update, if the audit rules had a typo or the command was not supported by the Linux kernel, either an error was triggered and you were able to stop processing the rules or, as the other option, you were able to ignore any errors in which case it completed everything it could but returned success. This update introduces the "-c" option to auditctl which works like the ignore option, but instead of returning success, the "-c" option returns failure if any rule triggers an error. Note that like the ignore option, the "-c" option continues to process all audit rules.

BZ#766920

This release adds support for a new kernel auditing feature that allows for inter-field comparisons. For each audit event, the Linux kernel collects information about what is causing the event. Now, you can use the "-C" option to compare: "auid", "uid", "euid", "suid", "fsuid", or "obj_uid"; and "gid", "egid", "sgid", "fsgid", or "obj_gid". The two groups cannot be mixed. Comparisons can use either the equal or not equal operators. Note that for this enhancement to work, the system must boot the Linux 2.6.32-244 kernel or later.

BZ#759311

Previously, the "--autosave" option did not work correctly when using Augeas in batch mode, which caused that configuration changes were not saved. As a consequence, configuration changes could be saved only in interactive mode. This update ensures that the "--autosave" option functions in batch mode as expected.

BZ#781690

Prior to this update, when parsing GRUB configuration files, Augeas did not parse the "--encrypted" option of the "password" command correctly. Instead, it parsed the "--encrypted" part as the password, and the password hash as a second "menu.lst" filename. This update ensures that the "--encrypted" option of the password command is parsed correctly when parsing GRUB configuration files.

BZ#820864

Previously, Augeas was not able to parse the /etc/fstab file containing mount options with an equals sign but no value. This update fixes the fstab lens so that it can handle such mount options. As a result, Augeas can now parse an /etc/fstab file containing mount options with an equals sign but no value correctly.

BZ#628507

Previously, the finite-automata-DOT graph tool (fadot) did not support the -h option. Consequently, when fadot was launched with the -h option the "Unknown option" message was displayed. This update adds support for the -h option and ensures that a help message is displayed when fadot is launched with the option.

BZ#808662

Previously, Augeas did not have a lens to parse the /etc/mdadm.conf file. Consequently, the tool for conversion of physical servers to virtual guests, Virt-P2V, could not convert physical hosts on MD devices. This update adds a new lens to parse the /etc/mdadm.conf file, enabling Virt-P2V to convert physical hosts on MD devices as expected.

BZ#689717

Prior to this update, SSSD configuration files failed to parse if the files were not correctly formatted. As a consequence, the authconfig utility could abort unexpectedly. With this update, the error is correctly handled, the configuration file is backed up, and a new file is created.

BZ#708850

Prior to this update, the man page "authconfig(8)" referred to non-existing obsolete configuration files. This update modifies the man page to point to configuration files that are currently modified by authconfig.

BZ#749700

Prior to this update, a deprecated "krb_kdcip" option was set instead of the "krb5_server" option when the SSSD configuration was updated. This update modifies the SSSD configuration setting to use the "krb5_server" option to set the Kerberos KDC server address.

BZ#755975

Prior to this update, the authconfig command always returned the exit value "1" when the "--savebackup" option was used, due to handling of nonexisting configuration files on the system. With this update, the exit value is "0" if the configuration backup succeeds even if some configuration files which can be handled by authconfig, are not present on the system.

BZ#731094

Prior to this update, the authconfig utility did not support the SSSD configuration with the IPA backend. This update allows to join an IPAv2 domain with the system via the ipa-client-install command.

BZ#804615

With this update, the nss_sss module is also used in the "services" entry of the nsswitch.conf file when configuring this file.

BZ#772946

A recent change to correct a problem with included map entry removal introduced a new problem with included map key look-up. The condition used in the previous patch was too broad and the map key lookup mechanism failed to find keys in an included multi-mount map entry. The condition has been modified so that keys in multi-mount map entries are now found correctly.

BZ#772356

A function that checks validity of a mount location was meant to check only for a small subset of map location errors. A recent improvement modification in error reporting inverted a logic test in this validating function. Consequently, the scope of the test was widened, which caused automount to report false-positive failures. With this update, the faulty logic test has been fixed and false-positive failures no longer occur.

BZ#790674

Previously, autofs submounts incorrectly handled shutdown synchronization and lock restrictions. As a consequence, automount could become unresponsive when submounts expired. With this update, the submount shuts down only after passing through the state ST_SHUTDOWN, ST_SHUTDOWN_PENDING, or ST_SHUTDOWN_FORCE, or when the state changes to ST_READY.

BZ#753964

Prior to this update, two IPv6 compatibility functions were erroneously not included in the autofs interface to the libtirpc library. This prevented the autofs IPv6 RPC code from working. With this update, the libtirpc interface code for autofs has been fixed.

BZ#782169

When using the legacy auto.net script for the hosts map, an error in the script for handling multiple occurrences of exports prevented the script from returning any of the exported paths. This bug has been fixed by modifying the script to select only a unique list of exports, thus eliminating duplicate exports.

BZ#787595

Due to changes to the mount.nfs utility to take advantage of the support for NFS mount options in the kernel, the RPC processing had moved from mount.nfs to the kernel. However, the kernel RPC had to wait for RPC requests to servers that were not available to time out, resulting in very slow interactive response when attempting an automount to a server that was not available. This update changes the autofs RPC code to detect this situation early and provide proper error messages as soon as possible.

BZ#760945

Previously, although the /net/ and /misc/ directories are exclusively used by the default /etc/auto.master utility, they were not specified in the autofs RPM package. As a result, the rpm utility reported them as not owned by any package. This update adds both these directories to the autofs spec file.

BZ#745527

Previously, the autofs init.d script failed to return proper usage messages if called with no arguments, or incorrect arguments. This bug has been fixed and the script now prints the usage information as expected.

BZ#683523

Initial support for the System Security Services Daemon (SSSD) as a map source has been added to the autofs package.

Bug Fixes

BZ#734458

When /etc/resolv.conf contained nameservers with disabled recursion, nslookup failed to resolve certain host names. With this update, a patch has been applied and nslookup now works as expected in the scenario described.

BZ#739406

Prior to this update, errors arising on automatic update of DNSSEC trust anchors were handled incorrectly. Consequently, the named daemon could become unresponsive on shutdown. With this update, the error handling has been improved and named exits on shutdown gracefully.

BZ#739410

The multi-threaded named daemon uses the atomic operations feature to speed-up access to shared data. This feature did not work correctly on 32-bit and 64-bit PowerPC architectures. Therefore, named sometimes became unresponsive on these architectures. This update disables the atomic operations feature on 32-bit and 64-bit PowerPC architectures, which ensures that named is now more stable and reliable and no longer hangs.

BZ#746694

Prior to this update, a race condition could occur on validation of DNSSEC-signed NXDOMAIN responses and named could terminate unexpectedly. With this update, the underlying code has been fixed and the race condition no longer occurs.

BZ#759502

The named daemon, configured as the master server, sometimes failed to transfer an uncompressible zone. The following error message was logged:

transfer of './IN': sending zone data: ran out of space

The code which handles zone transfers has been fixed and this error no longer occurs in the scenario described.

BZ#759503

During a DNS zone transfer, named sometimes terminated unexpectedly with an assertion failure. With this update, a patch has been applied to make the code more robust, and named no longer crashes in the scenario described.

BZ#768798

Previously, the rndc.key file was generated during package installation by the rndc-confgen -a command, but this feature was removed in Red Hat Enterprise Linux 6.1 because users reported that installation of bind package sometimes hung due to lack of entropy in /dev/random. The named initscript now generates rndc.key during the service startup if it does not exist.

BZ#786362

After the rndc reload command was executed, named failed to update DNSSEC trust anchors and emitted the following message to the log:

managed-keys-zone ./IN: Failed to create fetch for DNSKEY update

This issue was fixed in the 9.8.2rc1 upstream version.

BZ#789886

Due to an error in the bind spec file, the bind-chroot subpackage did not create a /dev/null device. In addition, some empty directories were left behind after uninstalling bind. With this update, the bind-chroot packaging errors have been fixed.

BZ#795414

The dynamic-db plug-ins were loaded too early which caused the configuration in the named.conf file to override the configuration supplied by the plug-in. Consequently, named sometimes failed to start. With this update the named.conf is parsed before plug-in initialization and named now starts as expected.

BZ#812900

Previously, when the /var/named directory was mounted the /etc/init.d/named initscript did not distinguish between situations when chroot configuration was enabled and when chroot was not enabled. Consequently, when stopping the named service the /var/named directory was always unmounted. The initscript has been fixed and now unmounts /var/named only when chroot configuration is enabled. As a result, /var/named stays mounted after the named service is stopped when chroot configuration is not enabled.

BZ#816164

Previously, the nslookup utility did not return a non-zero exit code when it failed to get an answer. Consequently, it was impossible to determine if an nslookup run was successful or not from the error code. The nslookup utility has been fixed and now it returns "1" as the exit code when fails to get answer.

Enhancements

BZ#735438

By default BIND returns resource records in round-robin order. The rrset-order option now supports fixed ordering. When this option is set, the resource records for each domain name are always returned in the order they are loaded from the zone file.

BZ#788870

Previously, named logged too many messages relating to external DNS queries. The severity of these error messages has been decreased from “notice” to “debug” so that the system log is not flooded with mostly unnecessary information.

BZ#790682

The named daemon now uses portreserve to reserve the Remote Name Daemon Control (RNDC) port to avoid conflicts with other services.

Bug Fixes

BZ#751776

The bind-dyndb-ldap plug-in refused to load an entire zone when it contained an invalid Resource Record (RR) with the same Fully Qualified Domain Name (FQDN) as the zone name (for example an MX record). With this update, the code for parsing Resource Records has been improved. If an invalid RR is encountered, an error message “Failed to parse RR entry” is logged and the zone continues to load successfully.

BZ#767489

When the first connection to an LDAP server failed, the bind-dyndb-ldap plug-in did not try to connect again. Consequently, users had to execute the "rndc reload" command to make the plug-in work. With this update, the plug-in periodically retries to connect to an LDAP server. As a result, user intervention is no longer required and the plug-in works as expected.

BZ#767492

When the zone_refresh period timed out and a zone was removed from the LDAP server, the plug-in continued to serve the removed zone. With this update, the plug-in no longer serves zones which have been deleted from LDAP when the zone_refresh parameter is set.

BZ#789356

When the named daemon received the rndc reload command or a SIGHUP signal and the plug-in failed to connect to an LDAP server, the plug-in caused named to terminate unexpectedly when it received a query which belonged to a zone previously handled by the plug-in. This has been fixed, the plug-in no longer serves its zones when connection to LDAP fails during reload and no longer crashes in the scenario described.

BZ#796206

The plug-in terminated unexpectedly when named lost connection to an LDAP server for some time, then reconnected successfully, and some zones previously present had been removed from the LDAP server. The bug has been fixed and the plug-in no longer crashes in the scenario described.

BZ#805871

Certain string lengths were incorrectly set in the plug-in. Consequently, the Start of Authority (SOA) serial number and expiry time were incorrectly set for the forward zone during ipa-server installation. With this update, the code has been improved and the SOA serial number and expiry time are set as expected.

BZ#811074

When a Domain Name System (DNS) zone was managed by a bind-dyndb-ldap plugin and a sub-domain was delegated to another DNS server, the plug-in did not put A or AAAA glue records in the “additional section” of a DNS answer. Consequently, the delegated sub-domain was not accessible by other DNS servers. With this update, the plug-in has been fixed and now returns A or AAAA glue records of a delegated sub-domain in the “additional section”. As a result, delegated zones are correctly resolvable in the scenario described.

BZ#818933

Previously, the bind-dyndb-ldap plug-in did not escape non-ASCII characters in incoming DNS queries correctly. Consequently, the plug-in failed to send answers for queries which contained non-ASCII characters such as “,”. The plug-in has been fixed and now correctly returns answers for queries with non-ASCII characters.

Enhancements

BZ#733371

The bind-dyndb-ldap plug-in now supports two new attributes, idnsAllowQuery and idnsAllowTransfer, which can be used to set ACLs for queries or transfers. Refer to /usr/share/doc/bind-dyndb-ldap/README for information on the attributes.

BZ#754433

The plug-in now supports the new zone attributes idnsForwarders and idnsForwardPolicy which can be used to configure forwarding. Refer to /usr/share/doc/bind-dyndb-ldap/README for a detailed description.

BZ#766233

The plug-in now supports zone transfers.

BZ#767494

The plug-in has a new option called sync_ptr that can be used to keep A and AAAA records and their PTR records synchronized. Refer to /usr/share/doc/bind-dyndb-ldap/README for a detailed description.

BZ#795406

It was not possible to store configuration for the plug-in in LDAP and configuration was only taken from the named.conf file. With this update, configuration information can be obtained from idnsConfigObject in LDAP. Note that options set in named.conf have lower priority than options set in LDAP. The priority will change in future updates. Refer to the README file for more details.

BZ#676194

Previously, the GNU linker could terminate unexpectedly with a segmentation fault when attempting to link together object files of different architectures (for example, an object file of 32-bit Intel P6 with an object file of Intel 64). This update modifies binutils so that the linker now generates an error message and refuses to link object files in the scenario described.

BZ#809616

When generating build-ID hashes, the GNU linker previously allocated memory for BSS sections. Consequently, the linker could use more memory than was necessary. This update modifies the linker to skip BSS sections and thus avoid unnecessary memory usage when generating build-ID hashes.

BZ#739444

With this update, backported patches have been included to support new AMD processors. Also, a duplicate entry for the bextr instruction has been removed from the disassembler's table.

BZ#739144

The GNU linker has been modified in order to improve performance of Table of Contents (TOC) addressability and Procedure Linkage Table (PLT) call stubs on the PowerPC and PowerPC 64 architectures.

Security Fixes

CVE-2006-1168

A buffer underflow flaw was found in the way the uncompress utility of BusyBox expanded certain archive files compressed using Lempel-Ziv compression. If a user were tricked into expanding a specially-crafted archive file with uncompress, it could cause BusyBox to crash or, potentially, execute arbitrary code with the privileges of the user running BusyBox.

CVE-2011-2716

The BusyBox DHCP client, udhcpc, did not sufficiently sanitize certain options provided in DHCP server replies, such as the client hostname. A malicious DHCP server could send such an option with a specially-crafted value to a DHCP client. If this option's value was saved on the client system, and then later insecurely evaluated by a process that assumes the option is trusted, it could lead to arbitrary code execution with the privileges of that process. Note: udhcpc is not used on Red Hat Enterprise Linux by default, and no DHCP client script is provided with the busybox packages.

BZ#751927

Prior to this update, the "findfs" command did not recognize Btrfs partitions. As a consequence, an error message could occur when dumping a core file. This update adds support for recognizing such partitions so the problem no longer occurs.

BZ#752134

If the "grep" command was used with the "-F" and "-i" options at the same time, the "-i" option was ignored. As a consequence, the "grep -iF" command incorrectly performed a case-sensitive search instead of an insensitive search. A patch has been applied to ensure that the combination of the "-F" and "-i" options works as expected.

BZ#782018

Prior to this update, the msh shell did not support the "set -o pipefail" command. This update adds support for this command.

BZ#809092

Previously, the msh shell could terminate unexpectedly with a segmentation fault when attempting to execute an empty command as a result of variable substitution (for example msh -c '$nonexistent_variable'). With this update, msh has been modified to correctly interpret such commands and no longer crashes in this scenario.

BZ#752132

Previously, the msh shell incorrectly executed empty loops. As a consequence, msh never exited such a loop even if the loop condition was false, which could cause scripts using the loop to become unresponsive. With this update, msh has been modified to execute and exit empty loops correctly, so that hangs no longer occur.

BZ#743343

Byacc's maximum stack depth was reduced from 10000 to 500 between byacc releases. If deep enough else-if structures were present in source code being compiled with byacc, this could lead to out-of-memory conditions, resulting in YACC Stack Overflow and build failure. This updated release restores the maximum stack depth to its original value, 10000. Note: the underlying LR algorithm still imposes a hard limit on the number of parsable else-if statements. Restoring the maximum stack depth to its original value means source code with deep else-if structures that previously compiled against byacc will again do so.

BZ#730695

Previously, when searching for AF_UNSPEC or AF_INET6 address families, the c-ares library fell back to the AF_INET family if no AF_INET6 addresses were found. Consequently, IPv4 addresses were returned even if only IPv6 addresses were requested. With this update, c-ares performs the fallback only when searching for AF_UNSPEC addresses.

BZ#730693

The ares_parse_a_reply() function leaked memory when the user attempted to parse an invalid reply. With this update, the allocated memory is freed properly and the memory leak no longer occurs.

BZ#713133

A switch statement inside the ares_malloc_data() public function was missing a terminating break statement. This could result in unpredictable behavior and sometimes the application terminated unexpectedly. This update adds the missing switch statement and the ares_malloc_data() function now works as intended.

BZ#695426

When parsing SeRVice (SRV) record queries, c-ares was accessing memory incorrectly on architectures that require data to be aligned in memory. This caused the program to terminate unexpectedly with the SIGBUS signal. With this update, c-ares has been modified to access the memory correctly in the scenario described.

BZ#640944

Previously, the ares_gethostbyname manual page did not document the ARES_ENODATA error code as a valid and expected error code. With this update, the manual page has been modified accordingly.

BZ#765599

Prior to this update, one of the examples provided in the getting-started.txt file did not work as expected if the daemon was prevented from accessing files in user-specified locations, for example by the SELinux policy. With this update, this problem is now documented in the getting-started.txt file.

BZ#765600

Prior to this update, the certmonger daemon was not configured to start by default when the package was installed. This update enables the certmonger service by default.

BZ#796542

Prior to this update, the "getcert" command could under certain circumstances, display the misleading error message "invalid option" when an option that required an argument was used and the argument was not specified. This update modifies the error code so that the correct message is now sent.

BZ#766167

Prior to this update, newly added certificates were not automatically visible. To see these certificates, servers had to be manually restarted. This update adds the emission of D-Bus signals over the message bus to allow applications to perform the actions they need to use a new certificate. Also, the new "-C" option was added to invoke a user-specified command.

BZ#696305

When installing multiple Linux Standard Base (LSB) services which only had LSB headers, the stop priority of the related LSB init scripts could have been miscalculated and set to "-1". With this update, the LSB init script ordering mechanism has been fixed, and the stop priority of the LSB init scripts is now set correctly.

BZ#706854

When an LSB init script requiring the "$local_fs" facility was installed with the "install_initd" command, the installation of the script could fail under certain circumstances. With this update, the underlying code has been modified to ignore this requirement because the "$local_fs" facility is always implicitly provided. LSB init scripts with requirements on "$local_fs" are now installed correctly.

BZ#771454

If an LSB init script contained "Required-Start" dependencies, but the LSB service installed was not configured to start in any runlevel, the dependencies could have been applied incorrectly. Consequently, the installation of the LSB service failed silently. With this update, chkconfig no longer strictly enforces "Required-Start" dependencies for installation if the service is not configured to start in any runlevel. LSB services are now installed as expected in this scenario.

BZ#771741

Previously, chkconfig did not handle dependencies between LSB init scripts correctly. Therefore, if an LSB service was enabled, LSB services that were depending on it could have been set up incorrectly. With this update, chkconfig has been modified to determine dependencies properly, and dependent LSB services are now set up as expected in this scenario.

Security Fix

CVE-2012-1586

A file existence disclosure flaw was found in mount.cifs. If the tool was installed with the setuid bit set, a local attacker could use this flaw to determine the existence of files or directories in directories not accessible to the attacker.

Note

mount.cifs from the cifs-utils package distributed by Red Hat does not have the setuid bit set. We recommend that administrators do not manually set the setuid bit for mount.cifs.

BZ#769923

The cifs.mount(8) manual page was previously missing documentation for several mount options. With this update, the missing entries have been added to the manual page.

BZ#770004

Previously, the mount.cifs utility did not properly update the "/etc/mtab" system information file when remounting an existing CIFS mount. Consequently, mount.cifs created a duplicate entry of the existing mount entry. This update adds the del_mtab() function to cifs.mount, which ensures that the old mount entry is removed from "/etc/mtab" before adding the updated mount entry.

BZ#796463

The mount.cifs utility did not properly convert user and group names to numeric UIDs and GIDs. Therefore, when the "uid", "gid" or "cruid" mount options were specified with user or group names, CIFS shares were mounted with default values. This caused shares to be inaccessible to the intended users because UID and GID is set to "0" by default. With this update, user and group names are properly converted so that CIFS shares are now mounted with specified user and group ownership as expected.

BZ#805490

The cifs.upcall utility did not respect the "domain_realm" section in the "krb5.conf" file and worked only with the default domain. Consequently, an attempt to mount a CIFS share from a different than the default domain failed with the following error message:

mount error(126): Required key not available

This update modifies the underlying code so that cifs.upcall handles multiple Kerberos domains correctly and CIFS shares can now be mounted as expected in a multi-domain environment.

BZ#748756

The cifs.upcall utility previously always used the "/etc/krb5.conf" file regardless of whether the user had specified a custom Kerberos configuration file. This update adds the "--krb5conf" option to cifs.upcall allowing the administrator to specify an alternate krb5.conf file. For more information on this option, refer to the cifs.upcall(8) manual page.

BZ#748757

The cifs.upcall utility did not optimally determine the correct service principal name (SPN) used for Kerberos authentication, which occasionally caused krb5 authentication to fail when mounting a server's unqualified domain name. This update improves cifs.upcall so that the method used to determine the SPN is now more versatile.

BZ#806337

This update adds the "backupuid" and "backupgid" mount options to the mount.cifs utility. When specified, these options grant a user or a group the right to access files with the backup intent. For more information on these options, refer to the mount.cifs(8) manual page.

Bug Fixes

BZ#759603

A race condition existed when a node lost contact with the quorum device at the same time as the token timeout period expired. The nodes raced to fence, which could lead to a cluster failure. To prevent the race condition from occurring, the cman and qdiskd interaction timer has been improved.

BZ#750314

Previously, a cluster partition and merge during startup fencing was not detected correctly. As a consequence, the DLM (Distributed Lock Manager) lockspace operations could become unresponsive. With this update, the partition and merge event is now detected and handled properly. DLM lockspace operations no longer become unresponsive in the described scenario.

BZ#745538

Multiple ping command examples on the qdisk(5) manual page did not include the -w option. If the ping command is run without the option, the action can timeout. With this update, the -w option has been added to those ping commands.

BZ#745161

Due to a bug in libgfs2, sentinel directory entries were counted as if they were real entries. As a consequence, the mkfs.gfs2 utility created file systems which did not pass the fsck check when a large number of journal metadata blocks were required (for example, a file system with block size of 512, and 9 or more journals). With this update, incrementing the count of the directory entry is now avoided when dealing with sentinel entries. GFS2 file systems created with large numbers of journal metadata blocks now pass the fsck check cleanly.

BZ#806002

When a node fails and gets fenced, the node is usually rebooted and joins the cluster with a fresh state. However, if a block occurs during the rejoin operation, the node cannot rejoin the cluster and the attempt fails during boot. Previously, in such a case, the cman init script did not revert actions that had happened during startup and some daemons could be erroneously left running on a node. The underlying source code has been modified so that the cman init script now performs a full rollback when errors are encountered. No daemons are left running unnecessarily in this scenario.

BZ#804938

The RELAX NG schema used to validate the cluster.conf file previously did not recognize the totem.miss_count_const constant as a valid option. As a consequence, users were not able to validate cluster.conf when this option was in use. This option is now recognized correctly by the RELAX NG schema, and the cluster.conf file can be validated as expected.

BZ#819787

The cmannotifyd daemon is often started after the cman utility, which means that cmannotifyd does not receive or dispatch any notifications on the current cluster status at startup. This update modifies the cman connection loop to generate a notification that the configuration and membership have changed.

BZ#749864

Incorrect use of the free() function in the gfs2_edit code could lead to memory leaks and so cause various problems. For example, when the user executed the gfs2_edit savemeta command, the gfs2_edit utility could become unresponsive or even terminate unexpectedly. This update applies multiple upstream patches so that the free() function is now used correctly and memory leaks no longer occur. With this update, save statistics for the gfs2_edit savemeta command are now reported more often so that users know that the process is still running when saving a large dinode with a huge amount of metadata.

BZ#742595

Previously, the gfs2_grow utility failed to expand a GFS file system if the file system contained only one resource group. This was due to the old code being based on GFS1 (which had different fields) that calculated distances between resource groups and did not work with only one resource group. This update adds the rgrp_size() function in libgfs2, which calculates the size of the resource group instead of determining its distance from the previous resource group. A file system with only one resource group can now be expanded successfully.

BZ#742293

Previously, the gfs2_edit utility printed unclear error messages when the underlying device did not contain a valid GFS2 file system, which could be confusing. With this update, users are provided with additional information in the aforementioned scenario.

BZ#769400

Previously, the mkfs utility provided users with insufficient error messages when creating a GFS2 file system. The messages also contained absolute build paths and source code references, which was unwanted. A patch has been applied to provide users with comprehensive error messages in the described scenario.

BZ#753300

The gfs_controld daemon ignored an error returned by the dlm_controld daemon for the dlmc_fs_register() function while mounting a file system. This resulted in a successful mount, but recovery of a GFS file system could not be coordinated using Distributed Lock Manager (DLM). With this update, mounting a file system is not successful under these circumstances and an error message is returned instead.

Enhancements

BZ#675723, BZ#803510

The gfs2_convert utility can be used on a GFS1 file system to convert a file system from GFS1 to GFS2. However, the gfs2_convert utility required the user to run the gfs_fsck utility prior to conversion, but because this tool is not included in Red Hat Enterprise Linux 6, users had to use Red Hat Enterprise Linux 5 to run this utility. With this update, the gfs2_fsck utility now allows users to perform a complete GFS1 to GFS2 conversion on Red Hat Enterprise Linux 6 systems.

BZ#678372

Cluster tuning using the qdiskd daemon and the device-mapper-multipath utility is a very complex operation, and it was previously easy to misconfigure qdiskd in this setup, which could consequently lead to a cluster nodes failure. Input and output operations of the qdiskd daemon have been improved to automatically detect multipath-related timeouts without requiring manual configuration. Users can now easily deploy qdiskd with device-mapper-multipath.

BZ#733298, BZ#740552

Previously, the cman utility was not able to configure Redundant Ring Protocol (RRP) correctly in corosync, resulting in RRP deployments not working propely. With this update, cman has been improved to configure RRP properly and to perform extra sanity checks on user configurations. It is now easier to deploy a cluster with RRP and the user is provided with more extensive error reports.

BZ#745150

With this update, Red Hat Enterprise Linux High Availability has been validated against the VMware vSphere 5.0 release.

BZ#749228

With this update, the fence_scsi fencing agent has been validated for use in a two-node cluster with High Availability LVM (HA-LVM).

BZ#758127

Previously, the environment variable "LRMD_MAX_CHILDREN" from the program /etc/sysconfig/pacemaker was not properly evaluated. As a result, the "max_child_count" variable in the Local Resource Management Daemon (lrmd) was not modified. With this update, the bug has been fixed so that the environment variable "LRMD_MAX_CHILDREN" is evaluated as expected.

BZ#786746

Previously, if Pacemaker attempted to cancel a recurring operation while the operation was executed, the Local Resource Management Daemon (lrmd) did not cancel the operation correctly. As a result the operation was not removed from the repeat list. With this update, a canceled operation is now marked to be removed from the repeat operation list if it is canceled during the execution so that recurring canceled operations are never executed again.

BZ#742431

Prior to this update, under certain circumstances, outgoing queues in inter-node communication of the modclusterd service could grow over time. To prevent this behavior, the inter-node communication is now better balanced and queues are restricted in size. Forced queue interventions are logged in the /var/log/clumond.log file.

BZ#794907

When the clustermon utility was used to get the cluster schema from the server, the schema was returned in an invalid format, preventing further processing. This bug has been fixed and clustermon now provides an exact copy of the schema in the described scenario.

BZ#738967

Users are now able to configure the maximum number of open files. This allows the conman daemon to easily manage a large number of nodes.

BZ#771600

Previous versions of the control-center package contained gnome-at-mobility, a script that requires a software component that is not distributed with Red Hat Enterprise Linux 6 nor is present in any of the available channels. With this update, the non-functional gnome-at-mobility script has been removed and is no longer distributed as part of the control-center package.

BZ#524942

The background configuration tool now uses the XDG Base Directory Specification to determine where to store its data file. By default, this file is located at ~/.config/gnome-control-center/backgrounds.xml. Users can change the ~/.config/ prefix by setting the XDG_DATA_HOME environment variable, or set the GNOMECC_USE_OLD_BG_PATH environment variable to 1 to restore the old behavior and use the ~/.gnome2/backgrounds.xml file.

BZ#632680

The control-center-extra package now includes a GNOME Control Center shell. This shell provides a user interface for launching the various Control Center utilities.

BZ#769465, BZ#801363

The GNOME Control Center now provides a configuration utility for Wacom graphics tablets, which replaces the wacompl utility.

BZ#700907

Prior to this update, Coolkey did not recognize Spice virtualized CAC cards unless the card contained at least 3 certificates. This update fixes this issue so that cards with one or two certificates are recognized by Coolkey as expected. Note that this issue may also have affected some non-virtualized CAC cards.

BZ#713132

Under certain error conditions, Coolkey could leak memory data because a variable buffer was not being freed properly. With this update, the aforementioned buffer is properly freed, and memory leaks no longer occur.

BZ#772172

The "pr -c [filename]" and "pr -v [filename]" commands, which serve to show control and non-printing characters, cause the pr utility to terminate with a segmentation fault in multibyte locales. With this update, the underlying code has been modified and the pr utility now works as expected.

BZ#771843

The "-Z" option of the ls command did not explain sufficiently that only the last format option is taken into consideration and the user did not understand why the "ls -Zl" and "ls -lZ" command returned a different output. With this update, the ls info documentation has been improved.

BZ#769874

The "tail --follow" command uses the inotify API to follow the changes in a file. However, inotify does not work on remote file systems and the tail utility should fall back to polling for files on such file systems. The remote file systems GPFS and FhGFS were missing from the remote file system list and therefore "tail --follow" did not display the updates to the file on these file systems. These file systems have been added to the remote file system list and the problem no longer occurs.

BZ#751974

If SELinux was enabled, the "ls -l" command leaked one string for each non-empty directory name specified on the command line. With this update, such strings are freed from the memory and the problem no longer occurs.

BZ#754057

The su utility could remain unresponsive if it ran a process that ignored the SIG_CHLD signal. This happened because the su utility uses the waitpid() function to wait for a child process. The loop mechanism with the waitpid() function waited for the process to be in the stopped status. However, a process masking the SIG_CHLD signal will never be in that status. With this update, the loop mechanism was improved to handle this situation correctly and the problem no longer occurs.

BZ#804604

In a non-interactive tcsh shell, the colorls.csh script returned the following error: tput: No value for $TERM and no -T specified

This happened because the tcsh shell did not short-circuit the evaluation of the logical AND in a colorls.csh expression. With this update, checking for an interactive shell has been modified and the script no longer returns the error message.

BZ#766461

In the default listing, the df utility showed long file system names including UUID. Consequently, the columns following the file system names were pushed to the right and made the df output hard to read. As long UUID system names are becoming more common, df now prints the referent when a long name refers to a symlink, and no file systems are specified.

BZ#691466

The user could not use octal digit mode when cleaning special set-user-id and set-group-id bits on a directory with the chmod tool. This is an upstream change, however as it was possible in all the previous Red Hat Enterprise Linux releases, it is necessary to provide backwards compatibility. Therefore, the chmod tool now again allows the user to clear the special bits on the directories using octal digit mode if the octal digit mode is at least 5 digits long.

BZ#741455

The mainconfig module passed an incorrect string pointer to the function that opens the corosync log file. If the path to the file (in cluster.conf) contained a non-existing directory, an incorrect error message was returned stating that there was a configuration file error. The correct error message is now returned informing the user that the log file cannot be created.

BZ#797192

The coroipcc library did not delete temporary buffers used for Inter-Process Communication (IPC) connections that are stored in the /dev/shm shared-memory file system. The /dev/shm memory resources became fully used and caused a Denial of Service event. The library has been modified so that applications delete temporary buffers if the buffers were not deleted by the corosync server. The /dev/shm system is now no longer cluttered with needless data.

BZ#758209

The range condition for the update_aru() function could cause incorrect checking of message IDs. The corosync utility entered the "FAILED TO RECEIVE" state and failed to receive multicast packets. The range value in the update_aru() function is no longer checked and the check is now performed using the fail_to_recv_const constant.

BZ#752159

If the corosync-notifyd daemon was running for a long time, the corosync process consumed an excessive amount of memory. This happened because the corosync-notifyd daemon failed to indicate that the no-longer used corosync objects were removed, resulting in memory leaks. The corosync-notifyd daemon has been fixed and the corosync memory usage no longer increases if corosync-notifyd is running for long periods of time.

BZ#743813

When a large cluster was booted or multiple corosync instances started at the same time, the CPG (Closed Process Group) events were not sent to the user. Therefore, nodes were incorrectly detected as no longer available, or as leaving and re-joining the cluster. The CPG service now checks the exit code in such scenarios properly and the CPG events are sent to users as expected.

BZ#743815

The OpenAIS EVT (Eventing) service sometimes caused deadlocks in corosync between the timer and serialize locks. The order of locking has been modified and the bug has been fixed.

BZ#743812

When corosync became overloaded, IPC messages could be lost without any notification. This happened because some services did not handle the error code returned by the totem_mcast() function. Applications that use IPC now handle the inability to send IPC messages properly and try sending the messages again.

BZ#747628

If both the corosync and cman RPM packages were installed on one system, the RPM verification process failed. This happened because both packages own the same directory but apply different rights to it. Now, the RPM packages have the same rights and the RPM verification no longer fails.

BZ#752951

corosync consumed excessive memory because the getaddrinfo() function leaked memory. The memory is now freed using the freeadrrinfo() function and getaddrinfo() no longer leaks memory.

BZ#773720

It was not possible to activate or deactivate debug logs at runtime due to memory corruption in the objdb structure. The debug logging can now be activated or deactivated on runtime, for example by the "corosync-objctl -w logging.debug=off" command.

BZ#743810

Each IPC connection uses 48 K in the stack. Previously, multi-threading applications with reduced stack size did not work correctly, which resulted in excessive memory usage. Temporary memory resources in a heap are now allocated to the IPC connections so that multi-threading applications no longer need to justify IPC connections' stack size.

BZ#746209

Prior to this update,the options --to-stdout and --no-absolute-filenames were not listed in the cpio (1) manual page. This update includes the missing options and corrects several misprints.

BZ#754291

If the kernel was configured with the Completely Fair Scheduler (CFS) Group Scheduling feature enabled (CONFIG_FAIR_GROUP_SCHED=y), the "runq" command of the crash utility did not display all tasks in CPU run queues. This update modifies the crash utility so that all tasks in run queues are now displayed as expected. Also, the "-d" option has been added to the "runq" command, which provides debugging information same as the /proc/sched_debug file.

BZ#768189

The "bt" command previously did not handle recursive non-maskable interrupts (NMIs) correctly on the Intel 64 and AMD64 architectures. As a consequence, the "bt" command could, under certain circumstances, display a task backtrace in an infinite loop. With this update, the crash utility has been modified to recognize a recursion in the NMI handler and prevent the infinite displaying of a backtrace.

BZ#782837

Under certain circumstances, the number of the "elf_prstatus" entries in the header of the compressed kdump core file could differ from the number of CPUs running when the system crashed. If such a core file was analyzed by the crash utility, crash terminated unexpectedly with a segmentation fault while displaying task backtraces. This update modifies the code so that the "bt" command now displays a backtrace as expected in this scenario.

BZ#797229

Recent changes in the code caused the crash utility to incorrectly recognize compressed kdump dump files for the 64-bit PowerPC architecture as dump files for the 32-bit PowerPC architecture. This caused the crash utility to fail during initialization. This update fixes the problem and the crash utility now recognizes and analyzes the compressed kdump dump files for the 32-bit and 64-bit PowerPC architectures as expected.

BZ#817247

The crash utility did not correctly handle situations when a user page was either swapped out or was not mapped on the IBM System z architecture. As a consequence, the "vm -p" command failed and either a read error occurred or an offset va1lue of a swap device was set incorrectly. With this update, crash displays the correct offset value of the swap device or correctly indicates that the user page is not mapped.

BZ#817248

The crash utility did not correctly handle situations when the "bt -t" and "bt -T" commands were run on an active task on a live system on the IBM System z architecture. Consequently, the commands failed with the "bt: invalid/stale stack pointer for this task: 0" error message. This update modifies the source code so that the "bt -t" and "bt -T" commands execute as expected.

BZ#736884

With this update, crash now supports the "sadump" dump file format created by the Fujitsu Stand Alone Dump facility.

BZ#738865

The crash utility has been modified to fully support the "ELF kdump" and "compressed kdump" dump file formats for IBM System z.

BZ#739096

The makedumpfile facility can be used to filter out specific kernel data when creating a dump file, which can cause the crash utility to behave unpredictably. With this update, the crash utility now displays an early warning message if any part of the kernel has been erased or filtered out by makedumpfile.

BZ#729018

Previously, the "trace.so" binary in the crash-trace-command package was compiled by the GCC compiler without the "-g" option. Therefore, no debugging information was included in its associated "trace.so.debug" file. This could affect a crash analysis performed by the Automatic Bug Reporting Tool (ABRT) and its retrace server. Also, proper debugging of crashes using the GDB utility was not possible under these circumstances. This update modifies the Makefile of crash-trace-command to compile the "trace.so" binary with the "RPM_OPT_FLAGS" flag, which ensures that the GCC's "-g" option is used during the compilation. Debugging and a crash analysis can now be performed as expected.

BZ#623105

Prior to this update, the shebang line of the modifyrepo.py script contained "#!/usr/bin/env python", so the system path was used to locate the Python executable. When another version of Python was installed on the system, and "/usr/local/python" was specified in the PATH environment variable, scripts did not work due to Python compatibility problems. With this update, the shebang line is modified to "#!/usr/bin/python", so that the system version of Python is always used.

BZ#746648

For some configurations, the cryptsetup utility incorrectly translated major:minor device pairs to device names in the /dev/ directory (for example, on HP Smart Array devices). With this update, the underlying source code has been modified to address this issue, and the cryptsetup utility now works as expected. (BZ#755478) * If a device argument for the "cryptsetup status" command included a /dev/mapper/ prefix, the prefix was duplicated in the command's output. The output was fixed and no longer includes duplicated strings.

BZ#794888

Prior to this update, the ctdb working directory, all subdirectories and the files within were created with incorrect SELinux contexts when the ctdb service was started. This update uses the post-install script to create the ctdb directory, and the command "/sbin/restorecon -R /var/ctdb" sets now the right SELinux context.

BZ#738410

Prior to this update, the textonly filter did not always correctly generate output when a single copy was requested. The textonly filter generates output for a single or multiple copies by spooling the output for one copy into a temporary file, then sending the content of that temporary file as many times as required. However, if the filter was used for the MIME-type conversion rather than as a PostScript Printer Description (PPD) filter, and a single copy was requested, the temporary file was not created and the program failed with the "No such file or directory" message. With this update, the textonly filter has been modified to create a temporary file regardless of the number of copies specified. The data is now sent to the printer as expected.

BZ#738914, BZ#740093

Previously, empty jobs could be created using the "lp" command either by submitting an empty file to print (for example by executing "lp /dev/null") or by providing an empty file as standard input. In this way, a job was created but was never processed. With this update, creation of empty print jobs is not allowed, and the user is now informed that no file is in the request.

BZ#806818

The German translation for the search page template of the web interface contained an error that prevented the search feature from functioning correctly: attempting to search for a printer in the CUPS web interface failed, and an error message was displayed in the browser. The bug in the search template has been fixed, and the search feature in the German locale now works as expected in this scenario.

BZ#784662

The db4 spec file incorrectly stated that the "License" is simply "BSD", whereas it is in fact licensed under both the BSD and Sleepycat licenses, the latter of which differs from the Berkeley Software Distribution (BSD) license by including a redistribution clause. This update corrects the spec file so it correctly states that the db4 software is provided under the "Sleepycat and BSD" license.

Bug Fixes

BZ#812832

The multipathd daemon was not correctly stopping waiter threads during shutdown. The waiter threads could access freed memory and cause the daemon to terminate unexpectedly during shutdown. With this update, the mutlipathd daemon now correctly stops the waiter threads before they can access any freed memory and no longer crashes during shutdown.

BZ#662433

When Device Mapper Multipath was stopped, multipathd did not disable the queue_if_no_path option on multipath devices by default. When multipathd was stopped during shutdown, I/O of the device was added to the queue if all paths to a device were lost, and the shutdown process became unresponsive. With this update, multipathd now sets the queue_without_daemon option to no by default. As a result, all multipath devices stop queueing when multipathd is stopped and multipath now shuts down as expected.

BZ#752989

Device Mapper Multipath uses regular expressions in built-in device configurations to determine a multipath device so as to apply the correct configuration to the device. Previously, some regular expressions for resolving the device vendor name and product ID were not specific enough. As a consequence, some devices could be matched with incorrect device configurations. With this update, the product and vendor regular expressions have been modified so that all multipath devices are now configured properly.

BZ#754586

After renaming a device, there was a race condition between multipathd and udev to rename the new multipath device nodes. If udev renamed the device node first, multipathd removed the device created by udev and failed to create the new device node. With this update, multipathd immediately creates the new device nodes, and the race condition no longer occurs. As a result, the renamed device is now available as expected.

BZ#769527

Previously, the flush_on_last_dev handling code did not implement handling of the queue feature properly. Consequently, even though the flush_on_last_del feature was activated, multipathd re-enabled queueing on multipath devices that could not be removed immediately after the last path device was deleted. With this update, the code has been fixed and when the user sets flush_on_last_del, their multipath devices correctly disable queueing, even if the devices cannot be closed immediately.

BZ#796384

Previously, Device Mapper Multipath used a fixed-size buffer to read the Virtual Device Identification page [0x83]. The buffer size was sometimes insufficient to accommodate the data sent by devices and the ALUA (Asymmetric Logical Unit Access) prioritizer failed. Device Mapper Multipath now dynamically allocates a buffer large enough for the Virtual Device Identification page and the ALUA prioritizer no longer fails in the scenario described.

BZ#744210

Previously, multipathd did not set the max_fds option by default, which sets the maximum number of file descriptors that multipathd can open. Also, the user_friendly_names setting could only be configured in the defaults section of /etc/multipath.conf. The user had to set max_fds manually and override the default user_friendly_names value in their device-specific configurations. With this update, multipath now sets max_fds to the system maximum by default, and user_friendly_names can be configured in the devices section of multipath.conf. Users no longer need to set max_fds for large setups, and they are able to select user_friendly_names per device type.

BZ#744756

Previously, to modify a built-in configuration, the vendor and product strings of the user's configuration had to be identical to the vendor and product strings of the built-in configuration. The vendor and product strings are regular expressions, and the user did not always know the correct vendor and product strings needed to modify a built-in configuration. With this update, the hwtable_regex_match option was added to the defaults section of multipath.conf. If it is set to yes, Multipath uses regular-expression matching to determine if the user's vendor and product strings match the built-in device configuration strings: the user can use the actual vendor and product information from their hardware in their device configuration, and it will modify the default configuration for that device. The option is set to no by default.

BZ#750132

Previously, multipathd was using a deprecated Out-of-Memory (OOM) adjustment interface. Consequently, the daemon was not protected from the OOM killer properly; the OOM killer could kill the daemon when memory was low and the user was unable to restore failed paths. With this update, multipathd now uses the new Out-of-Memory adjustment interface and can no longer be killed by the Out-of-Memory killer.

BZ#702222

The multipath.conf file now contains a comment which informs the user that the configuration must be reloaded for any changes to take effect.

BZ#751938

The multipathd daemon incorrectly exited with code 1 when multipath -h (print usage) was run. With this update, the underlying code has been modified and multipathd now returns code 0 as expected in the scenario described.

BZ#751039

Some multipathd threads did not check if multipathd was shutting down before they started their execution. Consequently, the multipathd daemon could terminate unexpectedly with a segmentation fault on shutdown. With this update, the multipathd threads now check if multipathd is shutting down before triggering their execution, and multipathd no longer terminates with a segmentation fault on shutdown.

BZ#467709

The multipathd daemon did not have a failover method to handle switching of path groups when multiple nodes were using the same storage. Consequently, if one node lost access to the preferred paths to a logical unit, while the preferred path of the other node was preserved, multipathd could end up switching back and forth between path groups. This update adds the followover failback method to device-mapper-multipath. If the followover failback method is set, multipathd does not fail back to the preferred path group, unless it just came back online. When multiple nodes are using the same storage, a path failing on one machine now no longer causes the path groups to continually switch back and forth.

Enhancements

BZ#737051

The NetApp brand name has been added to the documentation about the RDAC (Redundant Disk Array Controller) checker and prioritizer.

BZ#788963

The built-in device configuration for Fujitsu ETERNUS has been added.

BZ#760852

If the multipath checker configuration was set to tur, the checks were not performed asynchronously. If a device failed and the checker was waiting for the SCSI layer to fail back, the checks on other paths were kept waiting. The checker has been rewritten so as to check the paths asynchronously, and the path checking on other paths continues as expected.

BZ#799908

A built-in configuration for IBM XIV Storage System has been added.

BZ#799842

The NetApp LUN built-in configuration now uses the tur path checker by default. Also flush_on_last_del has been enabled, dev_loss_tmo has been set to infinity, fast_io_fail_tmo has been set to 5, and pg_init_retries has been set to 50.

BZ#656339

Previously, when dhclient was unsuccessful in obtaining or renewing an address, it restored the resolv.conf file from backup even when there were other dhclient processes running. Consequently, network traffic could be unnecessarily interrupted. The bug in dhclient-script has been fixed and dhclient now restores resolv.conf from backup only if there are no other dhclient processes running.

BZ#747017

A bug caused an infinite loop in a dhcpd process when dhcpd tried to parse the slp-service-scope option in dhcpd.conf. As a consequence, dhcpd entered an infinite loop on startup consuming 100% of the CPU cycles. This update improves the code and the problem no longer occurs.

BZ#752116

Previously, the DHCPv4 client did not check whether the address received in a DHCPACK message was already in use. As a consequence, it was possible that after a reboot two clients could have the same, conflicting, IP address. With this update, the bug has been fixed and DHCPv4 client now performs duplicate address detection (DAD) and sends a DHCPDECLINE message if the address received in DHCPACK is already in use, as per RFC 2131.

BZ#756759

When dhclient is invoked with the "-1" command-line option, it should try to get a lease once and on failure exit with status code 2. Previously, when dhclient was invoked with the "-1" command-line option, and then issued a DHCPDECLINE message, it continued in trying to obtain a lease. With this update, the dhclient code has been fixed. As a result, dhclient stops trying to obtain a lease and exits after sending DHCPDECLINE when started with the "-1" option.

BZ#789719

Previously, dhclient kept sending DHCPDISCOVER messages in an infinite loop when started with the "-timeout" option having a value of 3 or less (seconds). With this update, the problem has been fixed and the "-timeout" option works as expected with all values.

BZ#790686

The DHCP server daemon now uses portreserve for reserving ports 647 and 847 to prevent other programs from occupying them.

BZ#798735

All DHCPv6 options defined in RFC5970, except for the Boot File Parameters Option, were implemented. This allows the DHCPv6 server to pass boot file URLs back to IPv6-based netbooting clients (UEFI) based on the system's architecture.

Bug Fixes

BZ#736074

Prior to this update, memory could become corrupted if the initial table size exceeded 1024 buckets. This update modifies libdhash so that large initial table sizes now correctly allocate memory.

BZ#801393

Prior to this update, buffers were filled and one character above the allocated size would be set to the null terminator if the combination of two strings,concatenated by the function path_concat(), exceeded the size of the destination buffer. This update modifies the underlying code so that the null terminator is no longer added after the end of the buffer.

BZ#729971

Prior to this update, a grub installation failed silently on a dmraid mirror because the device geometry of RAID sets was not set properly. Consequently, the set partition's MBR failed to be created and the partition failed to boot. With this update, the underlying code has been modified and the geometry on dmraid devices is set up correctly.

BZ#729032

The dmraid binary was compiled without gcc's -g option and the debuginfo file did not contain the ".debug_info" section. Consequently, it was not possible to generate debugging information and debug dmraid properly. With this update, the binary has been compiled with the proper debugging options and the problem no longer occurs.

BZ#701501

When the dmraid tool was accessing a 4 KB sector or smaller, it returned a misleading error message. With this update, the library function that checks the device size has been modified and the error message is no longer displayed under these circumstances.

BZ#794792

A new subpackage, dnsmasq-utils, has been added. The dnsmasq-utils subpackage contains the dhcp_lease_time and dhcp_release utilities, which serve to query and remove DHCP server leases using the standard DHCP protocol.

BZ#788119

Previously, if a dracut module did not contain an "install" file, dracut could not execute the "installkernel" command. Consequently, the dracut fips-aesni module could not be included in the initramfs image. Now, "installkernel" can be correctly executed in the described scenario, thus fixing this bug.

BZ#761584

Previously, dracut failed to start up a degraded RAID array, resulting in a non-booting system. With this update, dracut uses the rd_retry kernel command-line parameter value and after rd_retry/2 seconds attempts to force the array to start, thus fixing this bug.

BZ#747840

During boot-up, dracut called the "udevadm settle" command several times. As a result, inconsequential messages about the command timeout were sometimes returned, creating clutter in the console output. This update fixes the bug and the messages are no longer returned in the described scenario.

BZ#735529

Occasionally, dracut attempted to assemble an array before all disks were available. As a result, dracut started the array in degraded mode or failed altogether. This bug has been fixed and dracut now forces degraded arrays to start only after a period of time controlled by the rd_retry kernel command-line parameter.

BZ#714039

The dracut package depended on the vconfig package although vconfig is not used by dracut. This update removes the dependency on vconfig.

BZ#794863

Previously, if a network interface was brought up, dracut waited for two seconds to detect that the link was up. For certain network cards, two seconds is not long enough. Consequently, the network was not properly set up and the system could not boot. Now, dracut waits for ten seconds, thus fixing this bug.

BZ#752584

Dracut did not set the broadcast address for network interfaces it started up, resulting in a 0.0.0.0 broadcast address. This bug has been fixed and the default broadcast address is now set properly on startup.

BZ#703164

The FILES section of the dracut man page has been amended to fix inaccurate content.

BZ#752073

If the user adds multiple "console=[tty]" parameters on the kernel command line, the last parameter specifies the primary console. Previously, dracut failed to initialize this console and instead initialized /dev/tty0 unconditionally. This bug has been fixed and dracut now initializes the correct console in the described scenario.

BZ#788618

When no user name and password were specified in an iSCSI interface, dracut reused the login information from a previous iSCSI parameter. Consequently, the authentication failed and the system did not boot up. This update fixes the bug.

BZ#722879

Previously, it was not possible to exclude a kernel driver from the initramfs image to reduce its size. This update introduces the "--omit-driver" option to provide this functionality.

BZ#752005

The "lsinitrd" command has been enhanced to support initramfs images compressed by the LZMA algorithm.

BZ#684713

Previously, the dropwatch utility could terminate unexpectedly with a segmentation fault. The failure was caused by a double-free error which occurred while issuing the start and stop messages. This update removes the freeing function calls from the underlying code, which prevents the dropwatch utility from crashing.

BZ#786021

Prior to this update, checksums for backup group descriptors appeared to be wrong when the "e2fsck -b" option read these group descriptors and cleared UNINIT flags to ensure that all inodes were scanned. As a consequence, warning messages were sent during the process. This update recomputes checksums after the flags are changed. Now, "e2fsck -b" completes without these checksum warnings.

BZ#795846

Prior to this update, e2fsck could discard valid inodes when using the "-E discard" option. As a consequence, the file system could become corrupted. This update modifies the underlying code so that disk regions containing valid inodes are no longer discarded.

BZ#715216

In a Coverity Scan analysis, an allocation, which was not checked for errors, was discovered. With this update, the allocation is now checked for errors, thus the bug is fixed.

BZ#674866

Prior to this update, the expect(1) manual page was not formatted properly. As a result, the content of the manual page was not readable. The formatting has been corrected to ensure easy readability.

BZ#735962

Prior to this update, the passmass script did not call the "su" binary with the full path (/bin/su). The passmass script has been modified to call "/bin/su" rather than "su", which is more secure.

BZ#742911

Due to incorrect characters matching, applications created by the autoexpect utility could terminate unexpectedly with a segmentation fault. With this update, the number of characters is matched correctly and applications created by autoexpect run successfully.

BZ#782859

Previously, the expect-devel subpackage contained a symbolic link to the expect library, which led to an unnecessary dependency. With this update, the link is located in the expect package.

BZ#752699

Prior to this update, starting targetadmin without the fcoe-target utility could cause the following output:

OSError: [Errno 2] No such file or directory: '/sys/kernel/config/target

This update modifies the underlying code so that now a warning message is displayed if targetcli is invoked without running the fcoe-target service.

BZ#813664

Prior to this update, fcoe-target-utils used the executable name "targetadmin" which did not reflect the current name in the upstream version. This update changes the name to "targetcli", to match the upstream version.

BZ#815981

Prior to this update, the configuration state was saved to "tcm_start.sh", and the fcoe-target init script restored the state from this file when the fcoe-target service was started. For increased reliability, this update uses a new method to save and restore fcoe-target configuration; it is now saved to "/etc/target/saveconfig.json".

BZ#750277

Prior to this update, the fcoe-target-utils packages for the Fibre Channel over Ethernet (FCoE) target mode were available only as technical preview. With this update, the fcoe-target-utils packages are fully supported in Red Hat Enterprise Linux 6.

BZ#804936

The "service fcoe status" command returned an incorrect return value when the fcoe service was running. With this update, the underlying code has been modified and fcoe now returns the correct code under these circumstances.

Bug Fixes

BZ#769681

The fence_rhevm fencing agent uses the Red Hat Enterprise Virtualization API to check the power status ("on" or "off") of a virtual machine. In addition to the "up" and "down" states, the API includes number of other states. Previously, only if the machine was in the "up" state, the "on" power status was returned. The "off" status was returned for all other states even if the machine was running. This allowed for successful fencing before the machine was really powered off. With this update, the fence_rhevm agent detects the power status of a cluster node more conservatively, and the "off" status is returned only if the machine is actually powered off, that is in the "down" state.

BZ#772597

Previously, the fence_soap_vmware fence agent was not able to work with more than one hundred machines in a cluster. Consequently, fencing a cluster node running in a virtual machine on VMWare with the fence_soap_vmware fence agent failed with the "KeyError: 'config.uuid'" error message. With this update, the underlying code has been fixed to support fencing on such clusters.

BZ#740484

Previously, the fence_ipmilan agent failed to handle passwd_script argument values that contained space characters. Consequently, it was impossible to use a password script that required additional parameters. This update ensures that fence_ipmilan accepts and properly parses values for the passwd_script argument with spaces.

BZ#771211

Previously, the fence_vmware_soap fence agent did not expose the proper virtual machine path for fencing. With this update, fence_vmware_soap has been fixed to support this virtual machine identification.

BZ#714841

Previously, certain fence agents did not generate correct metadata output. As a result, it was not possible to use the metadata for automatic generation of manual pages and user interfaces. With this update, all fence agents generate their metadata as expected.

BZ#771936

Possible buffer overflow and null dereference defects were found by automatic tools. With this update, these problems have been fixed.

BZ#785091

Fence agents that use an identity file for SSH terminated unexpectedly when a password was expected but was not provided. This bug has been fixed and proper error messages are returned in the described scenario.

BZ#787706

The fence_ipmilan fence agent did not respect the power_wait option and did not wait after sending the power-off signal to a device. Consequently, the device could terminate its shutdown sequence. This bug has been fixed and fence_ipmilan now waits before shutting down a machine as expected.

BZ#741339

The fence_scsi agent creates the fence_scsi.dev file that contains a list of devices that the node registered with during an unfence operation. This file was unlinked for every unfence action. Consequently, if multiple fence device entries were used in the cluster.conf file, fence_scsi.dev only contained the devices that the node registered with during the most recent unfence action. Now, instead of the unlink call, if the device currently being registered does not exists in fence_scsi.dev, it is added to the file.

BZ#804169

If the "delay" option was set to more than 5 seconds while a fence device was connected via the telnet_ssl utility, the connection timed out and the fence device failed. Now, the "delay" option is applied before the connection is opened, thus fixing this bug.

BZ#806883

Previously, XML metadata returned by a fence agent incorrectly listed all attributes as "unique". This update fixes this problem and the attributes are now marked as unique only when this information is valid.

BZ#806912

This update fixes a typographical error in an error message in the fence_ipmilan agent.

BZ#806897

Prior to this update, the fence agent for IPMI (Intelligent Platform Management Interface) could return an invalid return code when the "-M cycle" option was used. This invalid return code could cause invalid interpretation of a fence action, eventually causing the cluster to become unresponsive. This bug has been fixed and only predefined return codes are now returned in the described scenario.

BZ#804805

Previously, the fence_brocade fence agent did not distinguish the "action" option from the standard "option" option. Consequently, the "action" option was ignored and the node was always fenced. This bug has been fixed and both options are now properly recognized and acted upon.

Enhancement

BZ#742003

This updates adds the feature to access Fujitsu RSB fencing device using secure shell.

BZ#753974

Prior to this update, the libvirt-qpid plug-in did not handle exceptions correctly. As a consequence, the fence_virtd daemon could unexpectedly terminate with a segmentation fault if the connection to the specified qpid daemon failed. This update modifies the exception handling. Now, the fencing operation works as expected.

BZ#758392

Prior to this update, the hashing utility sha_verify did not handle errors correctly when a key file could not be read. As a consequence, the fence_virtd daemon could unexpectedly terminate with a segmentation fault when receiving a fencing request if fence_virtd failed to read the specified key file during startup. This update modifies the error handling if a key file cannot be read. Now, fence_virtd no longer terminates under these conditions.

BZ#761215

Prior to this update, the XML example for serial mode in the fence_virt.conf(5) man page contained an incorrect closing tag. This update corrects this tag.

BZ#806949

Prior to this update, the libvirt-qpid plug-in was linked directly against the qpid libraries instead of only the qmfv2 library. As a consequence, newer versions of the qpid libraries could not be used with the libvirt-qpid plug-in. This update no longer links against the qpid libraries directly. Now, also newer qpid libraries can be used with libvirt-qpid.

BZ#809101

Prior to this update, the fence_virtd.conf manpage and the fence_virtd.conf generator incorrectly stated that by default, fence_virtd listened on all network interfaces. Both have been amended to state that by default, fence_virtd listens on the default network interface.

BZ#688136

Previously, the file utility contained "magic" patterns that incorrectly detected files according to one byte only. Unicode text files starting with that particular byte could be therefore incorrectly recognized as DOS executable files. This update removes the problematic patterns. Patterns that match less than 16 bits are no longer accepted, and the utility no longer detects Unicode files as DOS executables.

BZ#709846

Previously, the "magic" pattern for detection of Dell BIOS headers was outdated. As a consequence, the file utility did not detect newer BIOS formats. The "magic" pattern has been updated, and the file utility now detects new formats of Dell BIOS properly.

BZ#719583

Previously, users were allowed to add new "magic" files only into the home directory. As a consequence, users were not able to configure "magic" patterns for certain special file formats system-wide. With this update, a backported patch provides a way to read "magic" patterns from the /etc/magic file.

BZ#733229

Previously, "magic" patterns for Python were insufficient. The file utility was therefore unable to detect a Python script according to the Python function definition. With this update, detection of Python is improved, and Python scripts are properly recognized.

BZ#747999

Previously, the file utility did not contain a "magic" pattern for detection of files compressed using the LZMA algorithm. As a consequence, the file utility was unable to detect these files. This update adds the missing "magic" pattern, and LZMA compressed files are now detected as expected.

BZ#758109

Previously, the file utility did not contain a "magic" pattern to detect the swap signature on Itanium microprocessors. As a consequence, the file utility was unable to detect the signature. This update adds the missing "magic" pattern, and the swap signature on Itanium microprocessors is detected as expected.

BZ#760083

Previously, the file utility did not parse the name of an RPM package from the RPM file. As a consequence, the utility did not print the name of the RPM package. This update adds a "magic" pattern for RPM package name parsing, and the name is now printed as expected.

BZ#704187

Prior to this update, the firstboot utility did not allow users to change the timezone. This update adds the timezone module to firstboot so that users can now change the timezone in the reconfiguration mode.

BZ#753658

Prior to this update, the firstboot service did not provide a status option. This update adds the "firstboot service status" option to show if firstboot is scheduled to run on the next boot or not.

BZ#676607

Previously, the "configure.in" file did not include information on how to handle 64-bit PowerPC architectures. Attempting to install the fontforge-devel multilib PowerPC and 64-PowerPC RPM packages on the same 64-bit PowerPC machine led to conflicts between those packages. This update modifies the "configure.in" file, so that fontforge-devel multilib RPM packages are allowed to be installed on the same machine. The conflicts no longer occur in the described scenario.

BZ#665837

Previously, if no USB support was available on a machine (for example, virtual machines on a hypervisor that disabled USB support for guests), the fprintd daemon received the SIGABRT signal, and therefore terminated abnormally. Such crashes did not cause any system failure; however, the Automatic Bug Reporting Tool (ABRT) was alerted every time. With this update, the underlying code has been modified so that the fprintd daemon now exits gracefully on machines with no USB support.

BZ#787116

The radtest command-line argument to request the PPP hint option was not parsed correctly. Consequently, radclient did not add the PPP hint to the request packet and the test failed. This update corrects the problem and radtest now functions as expected.

BZ#705723

After log rotation, the freeradius logrotate script failed to reload the radiusd daemon after a log rotation and log messages were lost. This update has added a command to the freeradius logrotate script to reload the radiusd daemon and the radiusd daemon reinitializes and reopens its log files after log rotation as expected.

BZ#712803

The radtest argument with the eap-md5 option failed because it passed the IP family argument when invoking the radeapclient utility and the radeapclient utility did not recognize the IP family. The radeapclient now recognizes the IP family argument and radtest now works with eap-md5 as expected.

BZ#700870

Previously, freeradius was compiled without the "--with-udpfromto" option. Consequently, with a multihomed server and explicitly specifying the IP address, freeradius sent the reply from the wrong IP address. With this update, freeradius has been built with the --with-udpfromto configuration option and the RADIUS reply is always sourced from the IP the request was sent to.

BZ#753764

The password expiration field for local passwords was not checked by the unix module and the debug information was erroneous. Consequently, a user with an expired password in the local password file was authenticated despite having an expired password. With this update, check of the password expiration has been modified. A user with an expired local password is denied access and correct debugging information is written to the log file.

BZ#690756

Due to invalid syntax in the PostgreSQL admin schema file, the FreeRADIUS PostgreSQL tables failed to be created. With this update, the syntax has been adjusted and the tables are created as expected.

BZ#782905

When FreeRADIUS received a request, it sometimes failed with the following message:

WARNING: Internal sanity check failed in event handler for request 6

This bug was fixed by upgrading to upstream version 2.1.12.

BZ#810605

FreeRADIUS has a thread pool that will dynamically grow based on load. If multiple threads using the rlm_perl() function are spawned in quick succession, freeradius sometimes terminated unexpectedly with a segmentation fault due to parallel calls to the rlm_perl_clone() function. With this update, mutex for the threads has been added and the problem no longer occurs.
