Hi David,
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a deadlock between mm->mmap_sem and bpf_event_mutex when
one task is detaching a BPF prog via perf_event_detach_bpf_prog()
and another one dumping through bpf_prog_array_copy_info(). For
the latter we move the copy_to_user() out of the bpf_event_mutex
lock to fix it, from Yonghong.
2) Fix test_sock and test_sock_addr.sh failures. The former was
hitting rlimit issues and the latter required ping to specify
the address family, from Yonghong.
3) Remove a dead check in sockmap's sock_map_alloc(), from Jann.
4) Add generated files to BPF kselftests gitignore that were previously
missed, from Anders.
