Summary
nfsd: check nfsd4_acl_to_attr() return value in nfsd4_create()
Details

In the Linux kernel, the following vulnerability has been resolved:

nfsd: check nfsd4_acl_to_attr() return value in nfsd4_create()

nfsd4_create() stores the return value of nfsd4_acl_to_attr() in status, but the switch(create->cr_type) block unconditionally overwrites it in every branch. ACL translation errors are silently discarded, and the CREATE proceeds without the requested ACL.

Add an early exit check after nfsd4_acl_to_attr(), matching the pattern already used in nfsd4_setattr().

[ cel: prefer NFS4ERR_BADTYPE over NFS4ERR_ATTRNOTSUPP ]
