From a8a5da996df7d2d91b5aef2752da9adcefea4bc6 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Thu, 9 Dec 2010 11:35:14 +0000 Subject: [PATCH] nfs: Set MS_POSIXACL always We want to skip VFS applying mode for NFS. So set MS_POSIXACL always and selectively use umask. Ideally we would want to use umask only when we don't have inheritable ACEs set. But NFS currently don't allow to send umask to the server. So this is best what we can do and this is consistent with NFSv3 Signed-off-by: Aneesh Kumar K.V Signed-off-by: Trond Myklebust --- fs/nfs/dir.c | 3 +-- fs/nfs/nfs4proc.c | 5 +++++ fs/nfs/super.c | 10 ++++++++++ 3 files changed, 16 insertions(+), 2 deletions(-) diff --git a/fs/nfs/dir.c b/fs/nfs/dir.c index 831d61c..6ceedc7 100644 --- a/fs/nfs/dir.c +++ b/fs/nfs/dir.c @@ -1352,8 +1352,7 @@ static struct dentry *nfs_atomic_lookup(struct inode *dir, struct dentry *dentry if (nd->flags & LOOKUP_CREATE) { attr.ia_mode = nd->intent.open.create_mode; attr.ia_valid = ATTR_MODE; - if (!IS_POSIXACL(dir)) - attr.ia_mode &= ~current_umask(); + attr.ia_mode &= ~current_umask(); } else { open_flags &= ~(O_EXCL | O_CREAT); attr.ia_valid = 0; diff --git a/fs/nfs/nfs4proc.c b/fs/nfs/nfs4proc.c index 78b0899..ca88f29 100644 --- a/fs/nfs/nfs4proc.c +++ b/fs/nfs/nfs4proc.c @@ -2486,6 +2486,7 @@ nfs4_proc_create(struct inode *dir, struct dentry *dentry, struct iattr *sattr, path = &ctx->path; fmode = ctx->mode; } + sattr->ia_mode &= ~current_umask(); state = nfs4_do_open(dir, path, fmode, flags, sattr, cred); d_drop(dentry); if (IS_ERR(state)) { @@ -2816,6 +2817,8 @@ static int nfs4_proc_mkdir(struct inode *dir, struct dentry *dentry, { struct nfs4_exception exception = { }; int err; + + sattr->ia_mode &= ~current_umask(); do { err = nfs4_handle_exception(NFS_SERVER(dir), _nfs4_proc_mkdir(dir, dentry, sattr), @@ -2916,6 +2919,8 @@ static int nfs4_proc_mknod(struct inode *dir, struct dentry *dentry, { struct nfs4_exception exception = { }; int err; + + sattr->ia_mode &= ~current_umask(); do { err = nfs4_handle_exception(NFS_SERVER(dir), _nfs4_proc_mknod(dir, dentry, sattr, rdev), diff --git a/fs/nfs/super.c b/fs/nfs/super.c index dd56eec..001f9cb 100644 --- a/fs/nfs/super.c +++ b/fs/nfs/super.c @@ -2496,6 +2496,11 @@ static void nfs4_clone_super(struct super_block *sb, sb->s_maxbytes = old_sb->s_maxbytes; sb->s_time_gran = 1; sb->s_op = old_sb->s_op; + /* + * The VFS shouldn't apply the umask to mode bits.
