ovl: ovl_dir_fsync() cleanup

2014-11-20T15:40:02Z

Check against !OVL_PATH_LOWER instead of OVL_PATH_MERGE. For a copied up directory the two are currently equivalent. Signed-off-by: Miklos Szeredi

ovl: pass dentry into ovl_dir_read_merged()

2014-11-20T15:40:01Z

Pass dentry into ovl_dir_read_merged() insted of upperpath and lowerpath. This cleans up callers and paves the way for multi-layer directory reads. Signed-off-by: Miklos Szeredi

ovl: don't poison cursor

2014-11-05T13:49:38Z

ovl_cache_put() can be called from ovl_dir_reset() if the cache needs to be rebuilt. We did list_del() on the cursor, which results in an Oops on the poisoned pointer in ovl_seek_cursor().

overlayfs: fix lockdep misannotation

2014-10-28T22:32:47Z

In an overlay directory that shadows an empty lower directory, say /mnt/a/empty102, do: touch /mnt/a/empty102/x unlink /mnt/a/empty102/x rmdir /mnt/a/empty102 It's actually harmless, but needs another level of nesting between I_MUTEX_CHILD and I_MUTEX_NORMAL.

ovl: fix check for cursor

2014-10-28T22:31:54Z

ovl_cache_entry.name is now an array not a pointer, so it makes no sense test for it being NULL. Detected by coverity. From: Miklos Szeredi Fixes: 68bf8611076a ("overlayfs: make ovl_cache_entry->name an array instead of +pointer") Signed-off-by: Miklos Szeredi Signed-off-by: Al Viro

overlayfs: barriers for opening upper-layer directory

2014-10-28T22:27:28Z

make sure that a) all stores done by opening struct file don't leak past storing the reference in od->upperfile b) the lockless side has read dependency barrier Signed-off-by: Al Viro
