Alexei Starovoitov f56407fa6e bpf: Remove bpf_lsm_file_mprotect from sleepable list. ... Technically the bpf programs can sleep while attached to bpf_lsm_file_mprotect, but such programs need to access user memory. So they're in might_fault() category. Which means they cannot be called from file_mprotect lsm hook that takes write lock on mm->mmap_lock. Adjust the test accordingly. Also add might_fault() to __bpf_prog_enter_sleepable() to catch such deadlocks early. Fixes: 1e6c62a882 ("bpf: Introduce sleepable BPF programs") Fixes: e68a144547 ("selftests/bpf: Add sleepable tests") Reported-by: Yonghong Song <yhs@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Link: https://lore.kernel.org/bpf/20200831201651.82447-1-alexei.starovoitov@gmail.com		2020-08-31 23:03:57 +02:00
