Description: The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: o CVE-2021-26341: Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage (bsc# 1201050). o CVE-2021-33655: Fixed out of bounds write with ioctl FBIOPUT_VSCREENINFO (bnc#1201635). o CVE-2021-33656: Fixed out of bounds write with ioctl PIO_FONT (bnc# 1201636). o CVE-2022-1462: Fixed an out-of-bounds read flaw in the TeleTYpe subsystem (bnc#1198829). The following non-security bugs were fixed: o Add missing recommends of kernel-install-tools to kernel-source-vanilla (bsc#1200442) o cifs: On cifs_reconnect, resolve the hostname again (bsc#1201926). o cifs: Simplify reconnect code when dfs upcall is enabled (bsc#1201926). o cifs: To match file servers, make sure the server hostname matches (bsc# 1201926). o cifs: fix memory leak of smb3_fs_context_dup::server_hostname (bsc# 1201926). o cifs: fix potential use-after-free in cifs_echo_request() (bsc#1201926). o cifs: set a minimum of 120s for next dns resolution (bsc#1201926). o cifs: use the expiry output of dns_query to schedule next resolution (bsc# 1201926). o kernel-binary.spec: Support radio selection for debuginfo. To disable debuginfo on 5.18 kernel a radio selection needs to be switched to a different selection. This requires disabling the currently active option and selecting NONE as debuginfo type. o kvm: emulate: Fix SETcc emulation function offsets with SLS (bsc#1201930). o kvm: emulate: do not adjust size of fastop and setcc subroutines (bsc# 1201930). o pahole 1.22 required for full BTF features. also recommend pahole for kernel-source to make the kernel buildable with standard config o rpm/*.spec.in: remove backtick usage o rpm/constraints.in: skip SLOW_DISK workers for kernel-source o rpm/kernel-obs-build.spec.in: Also depend on dracut-systemd (bsc#1195775) o rpm/kernel-obs-build.spec.in: add systemd-initrd and terminfo dracut module (bsc#1195775) o rpm/kernel-obs-build.spec.in: use default dracut modules (bsc#1195926, bsc# 1198484).
