From 83c475f8ef7d4f4b28f1bf77ae389c96c661f8f6 Mon Sep 17 00:00:00 2001 From: Tyler Hicks Date: Tue, 7 Feb 2012 17:55:40 -0600 Subject: [PATCH] eCryptfs: Copy up lower inode attrs after setting lower xattr After passing through a ->setxattr() call, eCryptfs needs to copy the inode attributes from the lower inode to the eCryptfs inode, as they may have changed in the lower filesystem's ->setxattr() path. One example is if an extended attribute containing a POSIX Access Control List is being set. The new ACL may cause the lower filesystem to modify the mode of the lower inode and the eCryptfs inode would need to be updated to reflect the new mode. https://launchpad.net/bugs/926292 Signed-off-by: Tyler Hicks Reported-by: Sebastien Bacher Cc: John Johansen Cc: --- fs/ecryptfs/inode.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/fs/ecryptfs/inode.c b/fs/ecryptfs/inode.c index 19892d7d2ed11..ab35b113003b9 100644 --- a/fs/ecryptfs/inode.c +++ b/fs/ecryptfs/inode.c @@ -1085,6 +1085,8 @@ ecryptfs_setxattr(struct dentry *dentry, const char *name, const void *value, } rc = vfs_setxattr(lower_dentry, name, value, size, flags); + if (!rc) + fsstack_copy_attr_all(dentry->d_inode, lower_dentry->d_inode); out: return rc; } -- 2.39.5
