====================
pull-request: bpf-next 2023-08-09

We've added 19 non-merge commits during the last 6 day(s) which contain
a total of 25 files changed, 369 insertions(+), 141 deletions(-).

The main changes are:

1) Fix array-index-out-of-bounds access when detaching from an
   already empty mprog entry from Daniel Borkmann.

2) Adjust bpf selftest because of a recent llvm change
   related to the cpu-v4 ISA from Eduard Zingerman.

3) Add uprobe support for the bpf_get_func_ip helper from Jiri Olsa.

4) Fix a KASAN splat due to the kernel incorrectly accepted
   an invalid program using the recent cpu-v4 instruction from
   Yonghong Song.
