The kernel packages contain the Linux kernel, the core of any Linux operating
system.
Security Fix(es):
The security impact of this issue was discovered by Red Hat.
Bug Fix(es):
Due to prematurely decremented calc_load_task, the calculated load average was
off by up to the number of CPUs in the machine. As a consequence, job scheduling
worked improperly causing a drop in the system performance. This update keeps
the delta of the CPU going into NO_HZ idle separately, and folds the pending
idle delta into the global active count while correctly aging the averages for
the idle-duration when leaving NO_HZ mode. Now, job scheduling works correctly,
ensuring balanced CPU load. (BZ#1308968)
Previously, the Stream Control Transmission Protocol (SCTP) retransmission
path selection was not fully RFC compliant when Partial Failover had been
enabled. The provided patch provides SCTP path selection updates, thus fixing
this bug. (BZ#1306565)
