From 9256af60ce919aead3a5c1fc7f75a138c56474e2 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 24 Aug 2014 14:46:48 -0400 Subject: [PATCH] NFSv3: Fix another acl regression When creating a new object on the NFS server, we should not be sending posix setacl requests unless the preceding posix_acl_create returned a non-trivial acl. Doing so, causes Solaris servers in particular to return an EINVAL. Fixes: 013cdf1088d72 (nfs: use generic posix ACL infrastructure,,,) Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1132786 Cc: stable@vger.kernel.org # 3.14+ Signed-off-by: Trond Myklebust --- fs/nfs/nfs3acl.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/fs/nfs/nfs3acl.c b/fs/nfs/nfs3acl.c index d0fec260132a..24c6898159cc 100644 --- a/fs/nfs/nfs3acl.c +++ b/fs/nfs/nfs3acl.c @@ -129,7 +129,10 @@ static int __nfs3_proc_setacls(struct inode *inode, struct posix_acl *acl, .rpc_argp = &args, .rpc_resp = &fattr, }; - int status; + int status = 0; + + if (acl == NULL && (!S_ISDIR(inode->i_mode) || dfacl == NULL)) + goto out; status = -EOPNOTSUPP; if (!nfs_server_capable(inode, NFS_CAP_ACLS)) -- 1.9.3
