SUSE Linux Enterprise Real Time Extension 12-SP5
______________________________________________________________________________
An update that solves 15 vulnerabilities, contains one
feature and has 18 fixes is now available.
Description:
The SUSE Linux Enterprise 12 SP5 RT kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
- CVE-2019-15126: Fixed a vulnerability in Broadcom and Cypress Wi-Fi
chips, used in RPi family of devices aka "Kr00k". (bsc#1167162)
- CVE-2020-27820: Fixed a vulnerability where a use-after-frees in
nouveau's postclose() handler could happen if removing device.
(bsc#1179599)
- CVE-2021-0920: Fixed a local privilege escalation due to an use after
free bug in unix_gc. (bsc#1193731)
- CVE-2021-0935: Fixed out of bounds write due to a use after free which
could lead to local escalation of privilege with System execution
privileges needed in ip6_xmit. (bsc#1192032)
- CVE-2021-4002: Added a missing TLB flush that could lead to leak or
corruption of data in hugetlbfs. (bsc#1192946)
- CVE-2021-28711: Fixed a rogue backends that could cause DoS of guests
via high frequency events by hardening blkfront against event channel
storms. (bsc#1193440)
- CVE-2021-28712: Fixed a rogue backends that could cause DoS of guests
via high frequency events by hardening netfront against event channel
storms. (bsc#1193440)
- CVE-2021-28713: Fixed a rogue backends that could cause DoS of guests
via high frequency events by hardening hvc_xen against event channel
storms. (bsc#1193440)
- CVE-2021-28714: Fixed an issue where a guest could force Linux netback
driver to hog large amounts of kernel memory by fixing rx queue stall
detection. (bsc#1193442)
- CVE-2021-28715: Fixed an issue where a guest could force Linux netback
driver to hog large amounts of kernel memory by do not queueing
unlimited number of packages. (bsc#1193442)
- CVE-2021-33098: Fixed a potential denial of service in Intel(R) Ethernet
ixgbe driver due to improper input validation. (bsc#1192877)
- CVE-2021-43975: Fixed a flaw in hw_atl_utils_fw_rpc_wait that could
allow an attacker (who can introduce a crafted device) to trigger an
out-of-bounds write via a crafted length value. (bsc#1192845)
- CVE-2021-43976: Fixed a flaw that could allow an attacker (who can
connect a crafted USB device) to cause a denial of service. (bsc#1192847)
- CVE-2021-45485: Fixed an information leak because of certain use of a
hash table which use IPv6 source addresses. (bsc#1194094)
- CVE-2021-45486: Fixed an information leak because the hash table is very
small in net/ipv4/route.c. (bsc#1194087)
The following non-security bugs were fixed:
- blk-mq: do not deactivate hctx if managed irq isn't used (bsc#1185762).
- cifs: fix missed refcounting of ipc tcon (git-fixes).
- cifs: nosharesock should be set on new server (git-fixes).
- config: INPUT_EVBUG=n (bsc#1192974). Debug driver unsuitable for
production, only enabled on ppc64.
- constraints: Build aarch64 on recent ARMv8.1 builders. Request asimdrdm
feature which is available only on recent ARMv8.1 CPUs. This should
prevent scheduling the kernel on an older slower builder.
- edac/amd64: Handle three rank interleaving mode (bsc#1114648).
- elfcore: correct reference to CONFIG_UML (git-fixes).
- fuse: release pipe buf after last use (bsc#1193318).
- genirq: Move initial affinity setup to irq_startup() (bsc#1193231).
- genirq: Provide IRQCHIP_AFFINITY_PRE_STARTUP (bsc#1193231).
- genirq: Remove mask argument from setup_affinity() (bsc#1193231).
- genirq: Rename setup_affinity() to irq_setup_affinity() (bsc#1193231).
- genirq: Split out irq_startup() code (bsc#1193231).
- kernel-*-subpackage: Add dependency on kernel scriptlets (bsc#1192740).
- kernel-binary.spec.in Stop templating the scriptlets for subpackages
(bsc#1190358). The script part for base package case is completely
separate from the part for subpackages. Remove the part for subpackages
from the base package script and use the KMP scripts for subpackages
instead.
- kernel-binary.spec.in: add zstd to BuildRequires if used
- kernel-binary.spec.in: make sure zstd is supported by kmod if used
- kernel-binary.spec: Check for no kernel signing certificates. Also
remove unused variable.
- kernel-binary.spec: Define $image as rpm macro (bsc#1189841).
- kernel-binary.spec: Do not fail silently when KMP is empty
(bsc#1190358). Copy the code from kernel-module-subpackage that deals
with empty KMPs.
- kernel-binary.spec: Do not sign kernel when no key provided
(bsc#1187167).
- kernel-binary.spec: Fix kernel-default-base scriptlets after packaging
merge.
- kernel-binary.spec: Require dwarves for kernel-binary-devel when BTF is
enabled (jsc#SLE-17288). About the pahole version: v1.18 should be bare
mnimum, v1.22 should be fully functional, for now we ship git snapshot
with fixes on top of v1.21.
- kernel-binary.spec: suse-kernel-rpm-scriptlets required for uninstall as
well. Fixes: e98096d5cf85 ("rpm: Abolish scritplet templating
(bsc#1189841).")
- kernel-cert-subpackage: Fix certificate location in scriptlets
(bsc#1189841). Fixes: d9a1357edd73 ("rpm: Define $certs as rpm macro
(bsc#1189841).")
- kernel-source.spec: install-kernel-tools also required on 15.4
- kernel-spec-macros: Since rpm 4.17 %verbose is unusable (bsc#1191229).
The semantic changed in an incompatible way so invoking the macro now
causes a build failure.
- lpfc: Reintroduce old IRQ probe logic (bsc#1183897).
- net: mana: Allow setting the number of queues while the NIC is down
(jsc#SLE-18779, bsc#1185727).
- net: mana: Fix spelling mistake "calledd" -> "called" (jsc#SLE-18779,
bsc#1185727).
- net: mana: Fix the netdev_err()'s vPort argument in mana_init_port()
(jsc#SLE-18779, bsc#1185727).
- net: mana: Improve the HWC error handling (jsc#SLE-18779, bsc#1185727).
- net: mana: Support hibernation and kexec (jsc#SLE-18779, bsc#1185727).
- net: mana: Use kcalloc() instead of kzalloc() (jsc#SLE-18779,
bsc#1185727).
- net: usb: lan78xx: lan78xx_phy_init(): use PHY_POLL instead of "0" if no
IRQ is available (git-fixes).
- nvme-fc: avoid race between time out and tear down (bsc#1185762).
- nvme-fc: remove freeze/unfreeze around update_nr_hw_queues (bsc#1185762).
- nvme-fc: update hardware queues before using them (bsc#1185762).
- nvme-fc: wait for queues to freeze before calling update_hr_hw_queues
(bsc#1183678).
- nvme-pci: add NO APST quirk for Kioxia device (git-fixes).
- platform/x86: hp_accel: Fix an error handling path in
'lis3lv02d_probe()' (git-fixes).
- platform/x86: thinkpad_acpi: Fix bitwise vs. logical warning (git-fixes).
- post.sh: detect /usr mountpoint too
- readme: Modernize build instructions.
- recordmcount.pl: fix typo in s390 mcount regex (bsc#1192267).
- recordmcount.pl: look for jgnop instruction as well as bcrl on s390
(bsc#1192267).
- rpm/kernel-binary.spec.in: Use kmod-zstd provide. This makes it possible
to use kmod with ZSTD support on non-Tumbleweed.
- rpm/kernel-binary.spec.in: avoid conflicting suse-release suse-release
had arbitrary values in staging, we can't use it for dependencies. The
filesystem one has to be enough (boo#1184804).
- rpm/kernel-binary.spec.in: do not strip vmlinux again (bsc#1193306)
After usrmerge, vmlinux file is not named vmlinux-<version>, but
simply vmlinux. And this is not reflected in STRIP_KEEP_SYMTAB we set.
So fix this by removing the dash...
- rpm/kernel-binary.spec: Use only non-empty certificates.
- rpm/kernel-obs-build.spec.in: make builds reproducible (bsc#1189305)
- rpm/kernel-source.rpmlintrc: ignore new include/config files In 5.13,
since 0e0345b77ac4, config files have no longer .h suffix. Adapt the
zero-length check. Based on Martin Liska's change.
- rpm/kernel-source.spec.in: do some more for vanilla_only Make sure: *
sources are NOT executable * env is not used as interpreter * timestamps
are correct We do all this for normal kernel builds, but not for
vanilla_only kernels (linux-next and vanilla).
- rpm: Abolish image suffix (bsc#1189841). This is used only with vanilla
kernel which is not supported in any way. The only effect is has is that
the image and initrd symlinks are created with this suffix. These
symlinks are not used except on s390 where the unsuffixed symlinks are
used by zipl. There is no reason why a vanilla kernel could not be used
with zipl as well as it's quite unexpected to not be able to boot when
only a vanilla kernel is installed. Finally we now have a backup zipl
kernel so if the vanilla kernel is indeed unsuitable the backup kernel
can be used.
- rpm: Abolish scritplet templating (bsc#1189841). Outsource kernel-binary
and KMP scriptlets to suse-module-tools. This allows fixing bugs in the
scriptlets as well as defining initrd regeneration policy independent of
the kernel packages.
- rpm: Define $certs as rpm macro (bsc#1189841). Also pass around only the
shortened hash rather than full filename. As has been discussed in
bsc#1124431 comment 51
https://bugzilla.suse.com/show_bug.cgi?id=1124431#c51 the placement of
the certificates is an API which cannot be changed unless we can ensure
that no two kernels that use different certificate location can be built
with the same certificate.
- rpm: Fold kernel-devel and kernel-source scriptlets into spec files
(bsc#1189841). These are unchanged since 2011 when they were introduced.
No need to track them separately.
- rpm: fix kmp install path
- rpm: support gz and zst compression methods Extend commit 18fcdff43a00
("rpm: support compressed modules") for compression methods other than
xz.
- rpm: use _rpmmacrodir (boo#1191384)
- scsi: core: Fix bad pointer dereference when ehandler kthread is invalid
(git-fixes).
- scsi: core: Put LLD module refcnt after SCSI device is released
