getsockname() returns EINVAL sometimes. I've read in other man pages this means "The socket has been shut down.". I haven't verified whether this is
true for NetBSD, so someone should have a look at the sources.
This can happen with non-blocking sockets when connect() returned EINPROGRESS. This is the relevant output from ktruss:

socket(0x2, 0x1, 0)                = 9           
fcntl(0x9, 0x3, 0)                 = 2           
fcntl(0x9, 0x4, 0x6)               = 0           
fcntl(0x9, 0x3, 0)                 = 6           
connect(0x9, 0x80d5c98, 0x10)      Err#36 EINPROGRESS
fcntl(0x9, 0x3, 0)                 = 6           
select(0xa, 0, 0x80d5bb8, 0, 0x80d5b88) = 0
fcntl(0x9, 0x3, 0)                 = 6           
fcntl(0x9, 0x4, 0x2)               = 0           
select(0xa, 0x80d5bc8, 0, 0, 0x80d5b78) = 1
getsockname(0x9, 0x80d5c98, 0x80d5c94) Err#22 EINVAL
