Public bug reported:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree
or a minimally backported form of that patch. The 4.4.121 upstream
stable stable patch set is now available. It should be included
in the Ubuntu kernel as well.
git://git.kernel.org/
TEST CASE: TBD
The following patches from the 4.4.121 stable release shall be
applied:
* Linux 4.4.121
* btrfs: preserve i_mode if __btrfs_set_acl() fails
* bpf, x64: implement retpoline for tail call
* dm io: fix duplicate bio completion due to missing ref count
* mpls, nospec: Sanitize array index in mpls_label_ok()
* net: mpls: Pull common label check into helper
* sctp: verify size of a new chunk in _sctp_make_chunk()
* s390/qeth: fix IPA command submission race
* s390/qeth: fix SETIP command handling
* sctp: fix dst refcnt leak in sctp_v6_get_dst()
* sctp: fix dst refcnt leak in sctp_v4_get_dst
* udplite: fix partial checksum initialization
* ppp: prevent unregistered channels from connecting to PPP units
* netlink: ensure to loop over all netns in genlmsg_multicast_allns()
* net: ipv4: don't allow setting net.ipv4.route.min_pmtu below 68
* net: fix race on decreasing number of TX queues
* ipv6 sit: work around bogus gcc-8 -Wrestrict warning
* hdlc_ppp: carrier detect ok, don't turn off negotiation
* fib_semantics: Don't match route with mismatching tclassid
* bridge: check brport attr show in brport_show
* Revert "led: core: Fix brightness setting when setting delay_off=0"
* x86/spectre: Fix an error message
* leds: do not overflow sysfs buffer in led_trigger_show
* x86/apic/vector: Handle legacy irq data correctly
* ARM: dts: LogicPD Torpedo: Fix I2C1 pinmux
* btrfs: Don't clear SGID when inheriting ACLs
* x86/syscall: Sanitize syscall table de-references under speculation fix
* KVM: mmu: Fix overlap between public and private memslots
* ARM: mvebu: Fix broken PL310_ERRATA_753970 selects
* nospec: Allow index argument to have const-qualified type
* media: m88ds3103: don't call a non-initalized function
* cpufreq: s3c24xx: Fix broken s3c_cpufreq_init()
* ALSA: hda: Add a power_save blacklist
* ALSA: usb-audio: Add a quirck for B&W PX headphones
* tpm_i2c_nuvoton: fix potential buffer overruns caused by bit glitches on
the bus
* tpm_i2c_infineon: fix potential buffer overruns caused by bit glitches on
the bus
* tpm: st33zp24: fix potential buffer overruns caused by bit glitches on the
bus
