Daniel Borkmann says: ==================== pull-request: bpf 2019-01-20 The following pull-request contains BPF updates for your *net* tree. The main changes are: 1) Fix a out-of-bounds access in __bpf_redirect_no_mac, from Willem. 2) Fix bpf_setsockopt to reset sock dst on SO_MARK changes, from Peter. 3) Fix map in map masking to prevent out-of-bounds access under speculative execution, from Daniel. 4) Fix bpf_setsockopt's SO_MAX_PACING_RATE to support TCP internal pacing, from Yuchung. 5) Fix json writer license in bpftool, from Thomas. 6) Fix AF_XDP to check if an actually queue exists during umem setup, from Krzysztof. 7) Several fixes to BPF stackmap's build id handling. Another fix for bpftool build to account for libbfd variations wrt linking requirements, from Stanislav. 8) Fix BPF samples build with clang by working around missing asm goto, from Yonghong. 9) Fix libbpf to retry program load on signal interrupt, from Lorenz. 10) Various minor compile warning fixes in BPF code, from Mathieu. ==================== Signed-off-by: David S.

selftests/bpf: retry tests that expect build-id

2019-01-17T15:43:18Z

While running test_progs in a loop I found out that I'm sometimes hitting "Didn't find expected build ID from the map" error. Looking at stack_map_get_build_id_offset() it seems that it is racy (by design) and can sometimes return BPF_STACK_BUILD_ID_IP (i.e. can't trylock current->mm->mmap_sem). Let's retry this test a single time.

selftests: tc-testing: fix parsing of ife type

2019-01-16T22:05:42Z

In iproute2 commit 90c5c969f0b9 ("fix print_0xhex on 32 bit"), the format specifier for the ife type changed from 0x%X to %#llX, causing systematic failures in the following TDC test cases: 7682 - Create valid ife encode action with mark and pass control ef47 - Create valid ife encode action with mark and pipe control df43 - Create valid ife encode action with mark and continue control e4cf - Create valid ife encode action with mark and drop control ccba - Create valid ife encode action with mark and reclassify control a1cf - Create valid ife encode action with mark and jump control cb3d - Create valid ife encode action with mark value at 32-bit maximum 95ed - Create valid ife encode action with prio and pass control aa17 - Create valid ife encode action with prio and pipe control 74c7 - Create valid ife encode action with prio and continue control 7a97 - Create valid ife encode action with prio and drop control f66b - Create valid ife encode action with prio and reclassify control 3056 - Create valid ife encode action with prio and jump control 7dd3 - Create valid ife encode action with prio value at 32-bit maximum 05bb - Create valid ife encode action with tcindex and pass control ce65 - Create valid ife encode action with tcindex and pipe control 09cd - Create valid ife encode action with tcindex and continue control 8eb5 - Create valid ife encode action with tcindex and continue control 451a - Create valid ife encode action with tcindex and drop control d76c - Create valid ife encode action with tcindex and reclassify control e731 - Create valid ife encode action with tcindex and jump control b7b8 - Create valid ife encode action with tcindex value at 16-bit maximum 2a9c - Create valid ife encode action with mac src parameter cf5c - Create valid ife encode action with mac dst parameter 2353 - Create valid ife encode action with mac src and mac dst parameters 552c - Create valid ife encode action with mark and type parameters 0421 - Create valid ife encode action with prio and type parameters 4017 - Create valid ife encode action with tcindex and type parameters fac3 - Create valid ife encode action with index at 32-bit maximnum 7c25 - Create valid ife decode action with pass control dccb - Create valid ife decode action with pipe control 7bb9 - Create valid ife decode action with continue control d9ad - Create valid ife decode action with drop control 219f - Create valid ife decode action with reclassify control 8f44 - Create valid ife decode action with jump control b330 - Create ife encode action with cookie Change 'matchPattern' values, allowing '0' and '0x0' if ife type is equal to 0, and accepting both '0x' and '0X' otherwise, to let these tests pass both with old and new tc binaries. While at it, fix a small typo in test case fac3 ('maximnum'->'maximum'). Signed-off-by: Davide Caratti Acked-by: Stephen Hemminger Signed-off-by: David S. Miller

selftests: tc-testing: fix tunnel_key failure if dst_port is unspecified

2019-01-16T05:58:17Z

After commit 1c25324caf82 ("net/sched: act_tunnel_key: Don't dump dst port if it wasn't set"), act_tunnel_key doesn't dump anymore the destination port, unless it was explicitly configured. This caused systematic failures in the following TDC test case: 7a88 - Add tunnel_key action with cookie parameter Avoid matching zero values of TCA_TUNNEL_KEY_ENC_DST_PORT to let the test pass again.

selftests: tc-testing: drop test on missing tunnel key id

2019-01-16T05:55:50Z

After merge of commit 80ef0f22ceda ("net/sched: act_tunnel_key: Allow key-less tunnels"), act_tunnel_key does not reject anymore requests to install 'set' rules where the key id is missing. Therefore, drop the following TDC testcase: ba4e - Add tunnel_key set action with missing mandatory id parameter because it's going to become a systematic fail as soon as userspace iproute2 will start supporting key-less tunnels.
