Changes in v3: - Initialize duration to 0 in selftests (Martin) Changes in v2: - Check sk_fullsock in map_update_elem (Martin)
Enable calling map_update_elem on sockmaps from bpf_iter context. This in turn allows us to copy a sockmap by iterating its elements. The change itself is tiny, all thanks to the ground work from Martin, whose series [1] this patch is based on. I updated the tests to do some copying, and also included two cleanups. 1: https://lore.kernel.org/bpf/20200925000337.3853598-1-ka...@fb.com/ Lorenz Bauer (4): bpf: sockmap: enable map_update_elem from bpf_iter selftests: bpf: Add helper to compare socket cookies selftests: bpf: remove shared header from sockmap iter test selftest: bpf: Test copying a sockmap and sockhash kernel/bpf/verifier.c | 2 +- net/core/sock_map.c | 3 + .../selftests/bpf/prog_tests/sockmap_basic.c | 100 +++++++++++------- .../selftests/bpf/progs/bpf_iter_sockmap.c | 32 ++++-- .../selftests/bpf/progs/bpf_iter_sockmap.h | 3 - 5 files changed, 90 insertions(+), 50 deletions(-) delete mode 100644 tools/testing/selftests/bpf/progs/bpf_iter_sockmap.h -- 2.25.1
