  <description>The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2021-26930: Fixed an improper error handling in blkback's grant mapping (XSA-365 bsc#1181843).
- CVE-2021-26931: Fixed an issue where Linux  kernel was treating grant mapping errors as bugs (XSA-362 bsc#1181753).
- CVE-2021-26932: Fixed improper error handling issues in Linux grant mapping (XSA-361 bsc#1181747).
  by remote attackers to read or write files via directory traversal in an XCOPY request (bsc#178372).
- CVE-2020-29368,CVE-2020-29374: Fixed an issue in copy-on-write implementation which could have granted unintended write access
  because of a race condition in a THP mapcount check (bsc#1179660, bsc#1179428).

The following non-security bugs were fixed:

- cifs: check all path components in resolved dfs target (bsc#1180906).
- cifs: fix check of tcon dfs in smb1 (bsc#1180906).
- cifs: fix nodfs mount option (bsc#1180906).
- cifs: introduce helper for finding referral server (bsc#1180906).
- kernel-{binary,source}.spec.in: do not create loop symlinks (bsc#1179082)
- kernel-binary.spec: Add back initrd and image symlink ghosts to filelist (bsc#1182140). Fixes: 76a9256314c3 ("rpm/kernel-{source,binary}.spec: do not include ghost symlinks (boo#1179082).")
- kernel-source.spec: Fix build with rpm 4.16 (boo#1179015). RPM_BUILD_ROOT is cleared before %%install. Do the unpack into RPM_BUILD_ROOT in %%install
- rpm/kernel-binary.spec.in: avoid using barewords (bsc#1179014) 
- rpm/kernel-binary.spec.in: avoid using more barewords (bsc#1179014) %split_extra still contained two.
- rpm/kernel-binary.spec.in: Fix compressed module handling for in-tree KMP (jsc#SLE-10886) 
- rpm/kernel-binary.spec.in: use grep -E instead of egrep (bsc#1179045) egrep is only a deprecated bash wrapper for "grep -E". So use the latter instead.
- rpm/kernel-module-subpackage: make Group tag optional (bsc#1163592)
- rpm/kernel-obs-build.spec.in: Add -q option to modprobe calls (bsc#1178401)
- rpm/kernel-{source,binary}.spec: do not include ghost symlinks (boo#1179082).
- rpm/mkspec: do not build kernel-obs-build on x86_32 We want to use 64bit kernel due to various bugs (bsc#1178762 to name one). There is: ExportFilter: ^kernel-obs-build.*\.x86_64.rpm$ . i586 in Factory's prjconf now. No other actively maintained distro (i.e. merging packaging branch) builds a x86_32 kernel, hence pushing to packaging directly.
- rpm/post.sh: Avoid purge-kernel for the first installed kernel (bsc#1180058)
- scripts/lib/SUSE/MyBS.pm: properly close prjconf Macros: section
