Daniel Borkmann says: ==================== pull-request: bpf 2018-02-09 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Two fixes for BPF sockmap in order to break up circular map references from programs attached to sockmap, and detaching related sockets in case of socket close() event. For the latter we get rid of the smap_state_change() and plug into ULP infrastructure, which will later also be used for additional features anyway such as TX hooks. For the second issue, dependency chain is broken up via map release callback to free parse/verdict programs, all from John. 2) Fix a libbpf relocation issue that was found while implementing XDP support for Suricata project. Issue was that when clang was invoked with default target instead of bpf target, then various other e.g. debugging relevant sections are added to the ELF file that contained relocation entries pointing to non-BPF related sections which libbpf trips over instead of skipping them. Test cases for libbpf are added as well, from Jesper. 3) Various misc fixes for bpftool and one for libbpf: a small addition to libbpf to make sure it recognizes all standard section prefixes. Then, the Makefile in bpftool/Documentation is improved to explicitly check for rst2man being installed on the system as we otherwise risk installing empty man pages; the man page for bpftool-map is corrected and a set of missing bash completions added in order to avoid shipping bpftool where the completions are only partially working, from Quentin. 4) Fix applying the relocation to immediate load instructions in the nfp JIT which were missing a shift, from Jakub. 5) Two fixes for the BPF kernel selftests: handle CONFIG_BPF_JIT_ALWAYS_ON=y gracefully in test_bpf.ko module and mark them as FLAG_EXPECTED_FAIL in this case; and explicitly delete the veth devices in the two tests test_xdp_{meta,redirect}.sh before dismantling the netnses as when selftests are run in batch mode, then workqueue to handle destruction might not have finished yet and thus veth creation in next test under same dev name would fail, from Yonghong. 6) Fix test_kmod.sh to check the test_bpf.ko module path before performing an insmod, and fallback to modprobe. Especially the latter is useful when having a device under test that has the modules installed instead, from Naresh. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
