====================
pull-request: bpf 2023-03-23
We've added 8 non-merge commits during the last 13 day(s) which contain
a total of 21 files changed, 238 insertions(+), 161 deletions(-).
The main changes are:
1) Fix verification issues in some BPF programs due to their stack usage
patterns, from Eduard Zingerman.
2) Fix to add missing overflow checks in xdp_umem_reg and return an error
in such case, from Kal Conley.
3) Fix and undo poisoning of strlcpy in libbpf given it broke builds for
libcs which provided the former like uClibc-ng, from Jesus Sanchez-Palencia.
4) Fix insufficient bpf_jit_limit default to avoid users running into hard
to debug seccomp BPF errors, from Daniel Borkmann.
5) Fix driver return code when they don't support a bpf_xdp_metadata kfunc
to make it unambiguous from other errors, from Jesper Dangaard Brouer.
6) Two BPF selftest fixes to address compilation errors from recent changes
in kernel structures, from Alexei Starovoitov.
