selftests: net: getsockopt_iter: cover rawv6 and tls

2026-08-03T23:55:23Z

Add fixtures for the newly converted getsockopt leaves: - rawv6: IPV6_HDRINCL / IPV6_CHECKSUM int paths + a SOL_RAW unknown-optname case that reaches do_rawv6_getsockopt(). - tls: TLS_TX_ZEROCOPY_RO, the TLS_TX crypto_info round-trip at the base and full cipher sizes, the NULL-optval and short buffer EINVAL paths, and an unknown optname. It skips when the kernel lacks TLS or AES-GCM. Each fixture pins the returned-length / errno semantics across exact, oversized and short buffers and an unknown optname. The semantics are unchanged by the sockopt_t conversion, so the tests pass both before and after the leaf conversions. ieee802154 and phonet are not covered: their CONFIG options are absent from the net selftest target config, so the cases would only ever skip.

selftests: net: getsockopt_iter: add raw ICMP_FILTER coverage

2026-07-02T10:29:06Z

Exercise the raw getsockopt path now backed by sockopt_t. ICMP_FILTER returns a fixed-size struct and, unlike the int/u64 options already covered, clamps the length down to the user buffer on a short read instead of failing, so check that semantic explicitly along with the exact and oversized cases, the -EOPNOTSUPP path on a non-ICMP raw socket, and an unknown optname.

selftests: net: getsockopt_iter: cleanup

2026-05-10T17:11:08Z

Apply two cleanups suggested by Stanislav and bobby on the original selftest series: - Reorder local variable declarations into reverse christmas-tree order (longest line first). Because that ordering puts socklen_t optlen before the variable whose size it stores, the "optlen = sizeof(...)" initializer is moved out of the declaration to a plain assignment in the test body, as Stanislav suggested. - Add ASSERT_EQ(optlen, ...) on every error path so the value the kernel writes back to the userspace optlen is pinned down even when the syscall returns -1. With do_sock_getsockopt() now writing opt->optlen back to userspace unconditionally, asserting that the netlink/vsock error paths leave the original input length untouched guards against future regressions. Bobby Eshleman pointed out that SO_VM_SOCKETS_CONNECT_TIMEOUT_NEW/OLD return a sock_timeval-shaped payload (16 bytes on 64-bit), which is wider than the u64 case already covered. Add four tests that exercise this path: - connect_timeout_new_exact exact-size buffer - connect_timeout_new_oversize_clamped oversize buffer, clamped - connect_timeout_new_undersize undersize -> -EINVAL, optlen untouched - connect_timeout_old_exact exact-size buffer for OLD optname Suggested-by: Stanislav Fomichev Suggested-by: Bobby Eshleman Signed-off-by: Breno Leitao Link: https://patch.msgid.link/20260507-getsock_two-v2-5-5873111d9c12@debian.org Signed-off-by: Jakub Kicinski

net: selftests: add getsockopt_iter regression tests

2026-05-05T02:02:30Z

Add a single kselftest covering the proto_ops getsockopt_iter conversions for AF_NETLINK and AF_VSOCK, using one fixture per protocol: netlink: NETLINK_PKTINFO covers the flag-style int path (exact size, oversize clamp, undersize -EINVAL); NETLINK_LIST_MEMBERSHIPS covers the size-discovery path that always reports the required buffer length back via optlen, even when the user buffer is too small to receive any group bits. vsock: SO_VM_SOCKETS_BUFFER_SIZE covers the u64 path (exact size, oversize clamp, undersize -EINVAL). Each fixture also exercises an unknown optname and a bogus level so the returned-length / errno semantics preserved by the sockopt_t conversion are pinned down.
