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: v5.4.47 upstream stable release from git://git.kernel.org/ ipv6: fix IPV6_ADDRFORM operation logic mlxsw: core: Use different get_trend() callbacks for different thermal zones net_failover: fixed rollback in net_failover_open() tun: correct header offsets in napi frags mode bridge: Avoid infinite loop when suppressing NS messages with invalid options vxlan: Avoid infinite loop when suppressing NS messages with invalid options bpf: Support llvm-objcopy for vmlinux BTF elfnote: mark all .note sections SHF_ALLOC Input: mms114 -
