From: Tyler Hicks <tyhicks@xxxxxxxxxxxxx> ------------------- This is a commit scheduled for the next v2.6.34 longterm release. http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git If you see a problem with using this for longterm, please comment. ------------------- commit 545d680938be1e86a6c5250701ce9abaf360c495 upstream. 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 <tyhicks@xxxxxxxxxxxxx> Reported-by: Sebastien Bacher <seb128@xxxxxxxxxx> Cc: John Johansen <john.johansen@xxxxxxxxxxxxx> Signed-off-by: Paul Gortmaker <paul.gortmaker@xxxxxxxxxxxxx> --- fs/ecryptfs/inode.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/fs/ecryptfs/inode.c b/fs/ecryptfs/inode.c index 168706e90e3f..532b97bb1f15 100644 --- a/fs/ecryptfs/inode.c +++ b/fs/ecryptfs/inode.c @@ -1057,6 +1057,8 @@ 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; } -- 1.8.5.2 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
