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 following upstream
stable patches should be included in the Ubuntu kernel:
v5.15.20 upstream stable release
from git://git.kernel.org/
Linux 5.15.20
ovl: fix NULL pointer dereference in copy up warning
tcp: add missing tcp_skb_can_collapse() test in tcp_shift_skb_data()
af_packet: fix data-race in packet_setsockopt / packet_setsockopt
e1000e: Handshake with CSME starts from ADL platforms
cpuset: Fix the bug that subpart_cpus updated wrongly in update_cpumask()
rtnetlink: make sure to refresh master_dev/m_ops in __rtnl_newlink()
net: sched: fix use-after-free in tc_new_tfilter()
fanotify: Fix stale file descriptor in copy_event_to_user()
net: amd-xgbe: Fix skb data length underflow
net: amd-xgbe: ensure to reset the tx_timer_active flag
i40e: Fix reset path while removing the driver
i40e: Fix reset bw limit when DCB enabled with 1 TC
ipheth: fix EOVERFLOW in ipheth_rcvbulk_callback
net/mlx5: E-Switch, Fix uninitialized variable modact
net/mlx5: Bridge, Fix devlink deadlock on net namespace deletion
net/mlx5e: Don't treat small ceil values as unlimited in HTB offload
net/mlx5: Fix offloading with ESWITCH_IPV4_TTL_MODIFY_ENABLE
net/mlx5e: Fix module EEPROM query
net/mlx5: Use del_timer_sync in fw reset flow of halting poll
net/mlx5e: Fix handling of wrong devices during bond netevent
net/mlx5: Bridge, ensure dev_name is null-terminated
net/mlx5: Bridge, take rtnl lock in init error handler
net/mlx5e: IPsec: Fix tunnel mode crypto offload for non TCP/UDP traffic
lockd: fix failure to cleanup client locks
lockd: fix server crash on reboot of client holding lock
ovl: don't fail copy up if no fileattr support on upper
Revert "mm/gup: small refactoring: simplify try_grab_page()"
cgroup-v1: Require capabilities to set release_agent
drm/vc4: hdmi: Make sure the device is powered with CEC
net: ipa: prevent concurrent replenish
net: ipa: use a bitmap for endpoint replenish_enabled
selftests: mptcp: fix ipv6 routing setup
PCI: pciehp: Fix infinite loop in IRQ handler upon power fault
