Daniel Borkmann says: ==================== pull-request: bpf 2021-01-16 1) Fix a double bpf_prog_put() for BPF_PROG_{TYPE_EXT,TYPE_TRACING} types in link creation's error path causing a refcount underflow, from Jiri Olsa. 2) Fix BTF validation errors for the case where kernel modules don't declare any new types and end up with an empty BTF, from Andrii Nakryiko. 3) Fix BPF local storage helpers to first check their {task,inode} owners for being NULL before access, from KP Singh. 4) Fix a memory leak in BPF setsockopt handling for the case where optlen is zero and thus temporary optval buffer should be freed, from Stanislav Fomichev. 5) Fix a syzbot memory allocation splat in BPF_PROG_TEST_RUN infra for raw_tracepoint caused by too big ctx_size_in, from Song Liu. 6) Fix LLVM code generation issues with verifier where PTR_TO_MEM{,_OR_NULL} registers were spilled to stack but not recognized, from Gilad Reti. * https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf: MAINTAINERS: Update my email address selftests/bpf: Add verifier test for PTR_TO_MEM spill bpf: Support PTR_TO_MEM{,_OR_NULL} register spilling bpf: Reject too big ctx_size_in for raw_tp test run libbpf: Allow loading empty BTFs bpf: Allow empty module BTFs bpf: Don't leak memory in bpf getsockopt when optlen == 0 bpf: Update local storage test to check handling of null ptrs bpf: Fix typo in bpf_inode_storage.c bpf: Local storage helpers should check nullness of owner ptr passed bpf: Prevent double bpf_prog_put call from bpf_tracing_prog_attach ==================== Link: https://lore.kernel.org/r/20210116002025.15706-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
