Hi David,
The following pull-request contains BPF updates for your *net-next* tree.
We've added 25 non-merge commits during the last 4 day(s) which contain
a total of 33 files changed, 2433 insertions(+), 161 deletions(-).
The main changes are:
1) Allow for adding TCP listen sockets into sock_map/hash so they can be used
with reuseport BPF programs, from Jakub Sitnicki.
2) Add a new bpf_program__set_attach_target() helper for adding libbpf support
to specify the tracepoint/function dynamically, from Eelco Chaudron.
3) Add bpf_read_branch_records() BPF helper which helps use cases like profile
guided optimizations, from Daniel Xu.
4) Enable bpf_perf_event_read_value() in all tracing programs, from Song Liu.
5) Relax BTF mandatory check if only used for libbpf itself e.g. to process
BTF defined maps, from Andrii Nakryiko.
6) Move BPF selftests -mcpu compilation attribute from 'probe' to 'v3' as it has
been observed that former fails in envs with low memlock, from Yonghong Song.
