- Fix kCFI failures in JITed BPF code on arm64 (Sami Tolvanen, Puranjay
Mohan, Mark Rutland, Maxwell Bland)
- Disallow tail calls between BPF programs that use different cgroup
local storage maps to prevent out-of-bounds access (Daniel Borkmann)
- Fix unaligned access in flow_dissector and netfilter BPF programs
(Paul Chaignon)
- Avoid possible use of uninitialized mod_len in libbpf (Achill
Gilgenast)
