btrfs: zero out left over bytes after processing compression streams

2014-11-30T17:33:51+00:00

Don Bailey noticed that our page zeroing for compression at end-io time
isn't complete.  This reworks a patch from Linus to push the zeroing
into the zlib and lzo specific functions instead of trying to handle the
corners inside btrfs_decompress_buf2page

"The biggest change is to rename the filesystem from "overlayfs" to "overlay".
This will allow legacy overlayfs to be easily carried by distros alongside the
new mainline one.  Also fix a couple of copy-up races and allow escaping comma
character in filenames."

The last bit is about commas in pathname mount options...

ovl: ovl_dir_fsync() cleanup

2014-11-20T15:40:02+00:00

Check against !OVL_PATH_LOWER instead of OVL_PATH_MERGE.  For a copied up
directory the two are currently equivalent.

ovl: pass dentry into ovl_dir_read_merged()

2014-11-20T15:40:01+00:00

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.

ovl: fix race in private xattr checks

2014-11-20T15:40:00+00:00

Xattr operations can race with copy up.  This does not matter as long as
we consistently fiter out "trunsted.overlay.opaque" attribute on upper
directories.

Previously we checked parent against OVL_PATH_MERGE.  This is too general,
and prone to race with copy-up.  I.e. we found the parent to be on the
lower layer but ovl_dentry_real() would return the copied-up dentry,
possibly with the "opaque" attribute.

So instead use ovl_path_real() and decide to filter the attributes based on
the actual type of the dentry we'll use.
