Description

When trying to connect to a linux NFS server using AUTH_SYS and a hostname with 33 bytes I get:
bad auth_len gid 0 str 36 auth 53

Looking at the Unix/Linux code at svc_auth_unix.c, it looks like the hostname length is rounded up to the nearest multiple of 4:
str_len = RNDUP(str_len);

Perhaps CredentialsSys should do that too?
