(RHSA-2019:2899) Important: kernel security and bug fix update

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. (CVE-2019-14835) * kernel: hw: Spectre SWAPGS gadget vulnerability (CVE-2019-1125) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Bug Fix(es): * fs deadlock when a memory allocation waits on page writeback in NOFS context (BZ#1729103) * fragmented packets timing out (BZ#1729409) * kernel build: speed up debuginfo extraction (BZ#1731460) * use "make -jN" for modules_install (BZ#1735079) * shmem: consider shm_mnt as a long-term mount (BZ#1737374) * raid1d can hang in freeze_array if handling a mix of read and write errors (BZ#1737792) * Backport TCP follow-up for small buffers (BZ#1739125)
