| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We'll use it to create tables for the 'protocol' argument to the socket syscall when the 'family' arg is one of AF_INET or AF_INET6. Add it to check_headers.sh so that when a new protocol gets added we get a notification during the build process.

The main changes are: 1) Add a new BPF hook for sendmsg similar to existing hooks for bind and connect: "This allows to override source IP (including the case when it's set via cmsg(3)) and destination IP:port for unconnected UDP (slow path). TCP and connected UDP (fast path) are not affected. This makes UDP support complete, that is, connected UDP is handled by connect hooks, unconnected by sendmsg ones.", from Andrey. 2) Rework of the AF_XDP API to allow extending it in future for type writer model if necessary. In this mode a memory window is passed to hardware and multiple frames might be filled into that window instead of just one that is the case in the current fixed frame-size model. With the new changes made this can be supported without having to add a new descriptor format. Also, core bits for the zero-copy support for AF_XDP have been merged as agreed upon, where i40e bits will be routed via Jeff later on. Various improvements to documentation and sample programs included as well, all from Björn and Magnus. 3) Given BPF's flexibility, a new program type has been added to implement infrared decoders. Quote: "The kernel IR decoders support the most widely used IR protocols, but there are many protocols which are not supported. [...] There is a 'long tail' of unsupported IR protocols, for which lircd is need to decode the IR. IR encoding is done in such a way that some simple circuit can decode it; therefore, BPF is ideal. [...] user-space can define a decoder in BPF, attach it to the rc device through the lirc chardev.", from Sean. 4) Several improvements and fixes to BPF core, among others, dumping map and prog IDs into fdinfo which is a straight forward way to correlate BPF objects used by applications, removing an indirect call and therefore retpoline in all map lookup/update/delete calls by invoking the callback directly for 64 bit archs, adding a new bpf_skb_cgroup_id() BPF helper for tc BPF programs to have an efficient way of looking up cgroup v2 id for policy or other use cases. Fixes to make sure we zero tunnel/xfrm state that hasn't been filled, to allow context access wrt pt_regs in 32 bit archs for tracing, and last but not least various test cases for fixes that landed in bpf earlier, from Daniel. 5) Get rid of the ndo_xdp_flush API and extend the ndo_xdp_xmit with a XDP_XMIT_FLUSH flag instead which allows to avoid one indirect call as flushing is now merged directly into ndo_xdp_xmit(), from Jesper. 6) Add a new bpf_get_current_cgroup_id() helper that can be used in tracing to retrieve the cgroup id from the current process in order to allow for e.g. aggregation of container-level events, from Yonghong. 7) Two follow-up fixes for BTF to reject invalid input values and related to that also two test cases for BPF kselftests, from Martin. 8) Various API improvements to the bpf_fib_lookup() helper, that is, dropping MPLS bits which are not fully hashed out yet, rejecting invalid helper flags, returning error for unsupported address families as well as renaming flowlabel to flowinfo, from David. 9) Various fixes and improvements to sockmap BPF kselftests in particular in proper error detection and data verification, from Prashant. 10) Two arm32 BPF JIT improvements. One is to fix imm range check with regards to whether immediate fits into 24 bits, and a naming cleanup to get functions related to rsh handling consistent to those handling lsh, from Wang. 11) Two compile warning fixes in BPF, one for BTF and a false positive to silent gcc in stack_map_get_build_id_offset(), from Arnd. 12) Add missing seg6.h header into tools include infrastructure in order to fix compilation of BPF kselftests, from Mathieu. 13) Several formatting cleanups in the BPF UAPI helper description that also fix an error during rst2man compilation, from Quentin. 14) Hide an unused variable in sk_msg_convert_ctx_access() when IPv6 is not built into the kernel, from Yue. 15) Remove a useless double assignment in dev_map_enqueue(), from Colin. ==================== Signed-off-by: David S.

The main changes are: 1) Add extensive BPF helper description into include/uapi/linux/bpf.h and a new script bpf_helpers_doc.py which allows for generating a man page out of it. Thus, every helper in BPF now comes with proper function signature, detailed description and return code explanation, from Quentin. 2) Migrate the BPF collect metadata tunnel tests from BPF samples over to the BPF selftests and further extend them with v6 vxlan, geneve and ipip tests, simplify the ipip tests, improve documentation and convert to bpf_ntoh*() / bpf_hton*() api, from William. 3) Currently, helpers that expect ARG_PTR_TO_MAP_{KEY,VALUE} can only access stack and packet memory. Extend this to allow such helpers to also use map values, which enabled use cases where value from a first lookup can be directly used as a key for a second lookup, from Paul. 4) Add a new helper bpf_skb_get_xfrm_state() for tc BPF programs in order to retrieve XFRM state information containing SPI, peer address and reqid values, from Eyal. 5) Various optimizations in nfp driver's BPF JIT in order to turn ADD and SUB instructions with negative immediate into the opposite operation with a positive immediate such that nfp can better fit small immediates into instructions. Savings in instruction count up to 4% have been observed, from Jakub. 6) Add the BPF prog's gpl_compatible flag to struct bpf_prog_info and add support for dumping this through bpftool, from Jiri. 7) Move the BPF sockmap samples over into BPF selftests instead since sockmap was rather a series of tests than sample anyway and this way this can be run from automated bots, from John. 8) Follow-up fix for bpf_adjust_tail() helper in order to make it work with generic XDP, from Nikita. 9) Some follow-up cleanups to BTF, namely, removing unused defines from BTF uapi header and renaming 'name' struct btf_* members into name_off to make it more clear they are offsets into string section, from Martin. 10) Remove test_sock_addr from TEST_GEN_PROGS in BPF selftests since not run directly but invoked from test_sock_addr.sh, from Yonghong. 11) Remove redundant ret assignment in sample BPF loader, from Wang. 12) Add couple of missing files to BPF selftest's gitignore, from Anders. There are two trivial merge conflicts while pulling: 1) Remove samples/sockmap/Makefile since all sockmap tests have been moved to selftests. 2) Add both hunks from tools/testing/selftests/bpf/.gitignore to the file since git should ignore all of them. ==================== Signed-off-by: David S.
