====================
pull-request: bpf 2023-10-11
We've added 14 non-merge commits during the last 5 day(s) which contain
a total of 12 files changed, 398 insertions(+), 104 deletions(-).
The main changes are:
1) Fix s390 JIT backchain issues in the trampoline code generation which
previously clobbered the caller's backchain, from Ilya Leoshkevich.
2) Fix zero-size allocation warning in xsk sockets when the configured
ring size was close to SIZE_MAX, from Andrew Kanner.
3) Fixes for bpf_mprog API that were found when implementing support
in the ebpf-go library along with selftests, from Daniel Borkmann
and Lorenz Bauer.
4) Fix riscv JIT to properly sign-extend the return register in programs.
This fixes various test_progs selftests on riscv, from Björn Töpel.
5) Fix verifier log for async callback return values where the allowed
range was displayed incorrectly, from David Vernet.
