a 0 error code. The problem occured with NFSv2 mounts and also with
any NFSv3 mount returning an EEXIST error (which is translated to 0
prior to return). The reply to the rpc only contains the file handle
for the no-error case under NFSv3. The error case under NFSv3 and
all cases under NFSv2 do *not* return the file handle. The fix is
to do a secondary lookup to obtain the file handle and thus be able
to generate a return vnode for the situations where the rpc reply
does not contain the required information.
The bug was originally introduced when VOP_SYMLINK semantics were
changed for -CURRENT. The NFS symlink implementation was not properly
modified to go along with the change despite the fact that three
people reviewed the code. It took four attempts to get the current
fix correct with five people. Is NFS obfuscated? Ha!
