Title:
Focal update: v5.4.116 upstream stable release
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Focal:
Fix Committed
Bug description:
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:
v5.4.116 upstream stable release
from git://git.kernel.org/
bpf: Move off_reg into sanitize_ptr_alu
bpf: Ensure off_reg has no mixed signed bounds for all types
bpf: Rework ptr_limit into alu_limit and add common error path
bpf: Improve verifier error messages for users
bpf: Refactor and streamline bounds check into helper
bpf: Move sanitize_val_alu out of op switch
bpf: Tighten speculative pointer arithmetic mask
bpf: Update selftests to reflect new error states
Linux 5.4.116
UBUNTU: upstream stable to v5.4.116
