8.111. libcgroup

Updated libcgroup packages that fix several bugs and add one enhancement are now available for Red Hat Enterprise Linux 6.
The libcgroup packages provide tools and libraries to manage and monitor control groups.

Bug Fixes

BZ#1022842
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#1028773
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#1057676
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#1060227
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#1080281
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.
In addition, this update adds the following

Enhancement

BZ#1058363
This update adds the /etc/cgconfig.d/ hierarchy designed to store configuration files applicable to various services.
Users of libcgroup are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.
