RHBA-2014:1480 - libcgroup bug fix and enhancement update

Synopsis

libcgroup bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated libcgroup packages that fix several bugs and add one enhancement are now available for Red Hat Enterprise Linux 6.

Description

The libcgroup packages provide tools and libraries to manage and monitor control groups.

This update fixes the following bugs:

• Previously, the cgset command failed to assign value to multiple subsystem parameters at once. This behavior occurred only when using the -r option more than once to tune parameters of a single subsystem. Configuring different subsystems simultaneously worked correctly. This bug has been fixed, and cgset can now set multiple parameters of a single subsystem without complications. (BZ#1022842)

• Previous libcgroup update introduced an unnecessary dependency on the redhat-lsb-core package. The redhat-lsb-core package subsequently pulled in a large number of other packages, which could cause problems on hardware with limited storage. With this update, the unnecessary dependency on the redhat-lsb-core package has been removed, and thus no unneeded packages are installed on system. (BZ#1028773)

• Prior to this update, the /src/config.c file contained the incorrectly specified cgroup_copy_cgroup() function. Consequently, certain user-specific resource limits set in the /etc/cgconfig.conf configuration file were not applied. This update fixes the syntax of the aforementioned function in /src/config.c. As a result, all settings in /etc/cgconfig.conf are applied as expected. (BZ#1057676)

• Previously applied patch that aimed to increase the performance of the pam_cgroup module contained a bug. Consequently, pam_cgroup failed to start and it did not produce an error message. With this update, the aforementioned patch has been reverted, and pam_cgroup now works as expected. (BZ#1060227)

• The cgset utility did not process all memory subsystem parameters passed to the --copy-from command-line option correctly. Consequently, these control group parameters were not transferred successfully and no warning message was issued. With this update, cgset has been modified to correctly process parameters of memory subsystem passed to --copy-from option, thus fixing this bug. (BZ#1080281)

In addition, this update adds the following enhancement:

• This update adds the /etc/cgconfig.d/ hierarchy designed to store configuration files applicable to various services. (BZ#1058363)

Users of libcgroup are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/articles/11258
