Hi David,

The following pull-request contains BPF updates for your *net* tree.

The main changes are:

1) Fix AF_XDP TX error reporting before final kernel release such that it
   becomes consistent between copy mode and zero-copy, from Magnus.

2) Fix three different syzkaller reported issues: oob due to ld_abs
   rewrite with too large offset, another oob in l3 based skb test run
   and a bug leaving mangled prog in subprog JITing error path, from Daniel.

3) Fix BTF handling for bitfield extraction on big endian, from Okash.

4) Fix a missing linux/errno.h include in cgroup/BPF found by kbuild bot,
   from Roman.

5) Fix xdp2skb_meta.sh sample by using just command names instead of
   absolute paths for tc and ip and allow them to be redefined, from Taeung.

6) Fix availability probing for BPF seg6 helpers before final kernel ships
   so they can be detected at prog load time, from Mathieu.

Please consider pulling these changes from:

  git://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git

Thanks a lot!
