| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge commit 1c8c5a9d38f60 ("Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next") undid the fix from commit 36f9814a494 ("bpf: fix uapi hole for 32 bit compat applications") by taking the gpl_compatible 1-bit field definition from commit b85fab0e67b162 ("bpf: Add gpl_compatible flag to struct bpf_prog_info") as is. That breaks architectures with 16-bit alignment like m68k. Add 31-bit pad after gpl_compatible to restore alignment of following fields. Thanks to Dmitry V. Levin his analysis of this bug history.

* bpf: remove useless version check for prog loadDaniel Borkmann2018-12-171-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | Existing libraries and tracing frameworks work around this kernel version check by automatically deriving the kernel version from uname(3) or similar such that the user does not need to do it manually; these workarounds also make the version check useless at the same time. Moreover, most other BPF tracing types enabling bpf_probe_read()-like functionality have /not/ adapted this check, and in general these days it is well understood anyway that all the tracing programs are not stable with regards to future kernels as kernel internal data structures are subject to change from release to release. Back at last netconf we discussed [0] and agreed to remove this check from bpf_prog_load() and instead document it here in the uapi header that there is no such guarantee for stable API for these programs.

It has three minor merge conflicts, resolutions: 1) tools/testing/selftests/bpf/test_verifier.c Take first chunk with alignment_prevented_execution. 2) net/core/filter.c [...] case bpf_ctx_range_ptr(struct __sk_buff, flow_keys): case bpf_ctx_range(struct __sk_buff, wire_len): return false; [...] 3) include/uapi/linux/bpf.h Take the second chunk for the two cases each. The main changes are: 1) Add support for BPF line info via BTF and extend libbpf as well as bpftool's program dump to annotate output with BPF C code to facilitate debugging and introspection, from Martin. 2) Add support for BPF_ALU | BPF_ARSH | BPF_{K,X} in interpreter and all JIT backends, from Jiong. 3) Improve BPF test coverage on archs with no efficient unaligned access by adding an "any alignment" flag to the BPF program load to forcefully disable verifier alignment checks, from David. 4) Add a new bpf_prog_test_run_xattr() API to libbpf which allows for proper use of BPF_PROG_TEST_RUN with data_out, from Lorenz. 5) Extend tc BPF programs to use a new __sk_buff field called wire_len for more accurate accounting of packets going to wire, from Petar. 6) Improve bpftool to allow dumping the trace pipe from it and add several improvements in bash completion and map/prog dump, from Quentin. 7) Optimize arm64 BPF JIT to always emit movn/movk/movk sequence for kernel addresses and add a dedicated BPF JIT backend allocator, from Ard. 8) Add a BPF helper function for IR remotes to report mouse movements, from Sean. 9) Various cleanups in BPF prog dump e.g. to make UAPI bpf_prog_info member naming consistent with existing conventions, from Yonghong and Song. 10) Misc cleanups and improvements in allowing to pass interface name via cmdline for xdp1 BPF example, from Matteo. 11) Fix a potential segfault in BPF sample loader's kprobes handling, from Daniel T. 12) Fix SPDX license in libbpf's README.rst, from Andrey. ==================== Signed-off-by: David S.
