The kernel Linux Distribution Packages contain the Linux
kernel, the core of any Linux operating system. Security Fix(es): * A flaw was
found in the Linux kernel's handling of packets with the URG flag. Applications
using the splice() and tcp_splice_read() functionality can allow a remote
attacker to force the kernel to enter a condition in which it can loop
indefinitely. (CVE-2017-6214, Moderate) Bug Fix(es): * When executing certain
Hadoop jobs, a kernel panic occasionally occurred on multiple nodes of a
cluster. This update fixes the kernel scheduler, and the kernel panic no longer
occurs under the described circumstances. (BZ#1436241) * Previously, memory leak
of the struct cred data structure and related data structures occasionally
occurred. Consequently, system performance was suboptimal with the symptoms of
high I/O operations wait and small amount of free memory. This update fixes the
reference counter of the struct slab cache to no longer cause imbalance between
the calls to the get_cred() function and the put_cred() function. As a result,
the memory leak no longer occurs under the described circumstances. (BZ#1443234)
* Previously, the be2net driver could not detect the link status properly on IBM
Power Systems. Consequently, the link status was always reported as
disconnected. With this update, be2net has been fixed, and the Network Interface
Cards (NICs) now report the link status correctly. (BZ#1442979) * Previously,
the RFF_ID and RFT_ID commands in the lpfc driver were issued in an incorrect
order. Consequently, users were not able to access Logical Unit Numbers (LUNs).
With this update, lpfc has been fixed to issue RFT_ID before RFF_ID, which is
the correct order. As a result, users can now access LUNs as expected.
(BZ#1439636) * Previously, the kdump mechanism was trying to get the lock by the
vmalloc_sync_all() function during a kernel panic. Consequently, a deadlock
occurred, and the crashkernel did not boot. This update fixes the
vmalloc_sync_all() function to avoid synchronizing the vmalloc area on the
crashing CPU. As a result, the crashkernel parameter now boots as expected, and
the kernel dump is collected successfully under the described circumstances.
