Hi David, hi Jakub, hi Paolo, hi Eric, The following pull-request contains BPF updates for your *net-next* tree. 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.
