If I use i386 however, it passes. I suspect (based on the size discrepancy) that one or more fields are being sized incorrectly (as pointers instead of scalars). In particular, the amount sent when testing on i386 is 96 bytes, whereas on amd64 it's 104 bytes. The reason why this is happening is the sizes in one = of the fields mismatch (another bug is coming soon for this hidden requirement buried in the kernel). amd64: $ cd tools/regression/sockets/unix_cmsg $ make -s clean $ make -s all $ ./unix_cmsg Running tests for SOCK_STREAM sockets: 1: Sending, receiving cmsgcred 2: Receiving sockcred (listening socket) 3: Receiving sockcred (accepted socket) 4: Sending cmsgcred, receiving sockcred 5: Sending, receiving timeval 6: Sending, receiving bintime 7: Check cmsghdr.cmsg_len CLIENT: sent message with cmsghdr.cmsg_len 12 < 16 SERVER: client exit status is 1 8: Check LOCAL_PEERCRED socket option -- 1 test failed!
