Parameters were created using wrong C types, which caused them to be of wrong size on some architectures, causing problems. The problem with SO_RCVLOWAT was found on s390 (big endian), while x86-64 didn't show it. After the fix, all tests pass on s390. Then Stefano Garzarella pointed out that SO_VM_SOCKETS_* calls might have a similar problem, which turned out to be true, hence, the second patch. Changes for v8: - Fix whitespace warnings from "checkpatch.pl --strict" - Add maintainers to Cc: Changes for v7: - Rebase on top of https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git - Add the "net" tags to the subjects Changes for v6: - rework the patch #3 to avoid creating a new file for new functions, and exclude vsock_perf from calling the new functions. - add "Reviewed-by:" to the patch #2. Changes for v5: - in the patch #2 replace the introduced uint64_t with unsigned long long to match documentation - add a patch #3 that verifies every setsockopt() call. Changes for v4: - add "Reviewed-by:" to the first patch, and add a second patch fixing SO_VM_SOCKETS_* calls, which depends on the first one (hence, it's now a patch series.) Changes for v3: - fix the same problem in vsock_perf and update commit message Changes for v2: - add "Fixes:" lines to the commit message Konstantin Shkolnyy (3): vsock/test: fix failures due to wrong SO_RCVLOWAT parameter vsock/test: fix parameter types in SO_VM_SOCKETS_* calls vsock/test: verify socket options after setting them tools/testing/vsock/control.c | 9 +- tools/testing/vsock/msg_zerocopy_common.c | 10 -- tools/testing/vsock/msg_zerocopy_common.h | 1 - tools/testing/vsock/util.c | 142 ++++++++++++++++++++++ tools/testing/vsock/util.h | 7 ++ tools/testing/vsock/vsock_perf.c | 20 ++- tools/testing/vsock/vsock_test.c | 75 ++++++------ tools/testing/vsock/vsock_test_zerocopy.c | 2 +- tools/testing/vsock/vsock_uring_test.c | 2 +- 9 files changed, 204 insertions(+), 64 deletions(-) -- 2.34.1
