gNFS: Incorrect NFS ACL encoding for XFS

2013-09-29T23:54:37+00:00

Problem:
Incorrect NFS ACL encoding causes "system.posix_acl_default"
setxattr failure on bricks on XFS file system. XFS (potentially
others?) doesn't understand when the 0x10 prefix is added to the
ACL type field for default ACLs (which the Linux NFS client adds)
which causes setfacl()->setxattr() to fail silently. NFS client
adds NFS_ACL_DEFAULT(0x1000) for default ACL.

FIX:
Mask the prefix (added by NFS client) OFF, so the setfacl is not
rejected when it hits the FS.

mount/fuse: perform lookup() on inodes linked through readdirplus

2013-08-23T19:09:58+00:00

Some xlators still require lookup() fop to be sent for proper working.
This patch remembers inodes which have been linked through readdiprlus
and makes the resolver send lookups on them.

md-cache: invalidate attributes on xattr update

2013-08-20T06:03:27+00:00

xattr update will result in at least ctime change. So invalidate
attributes in xattr callback.

glusterfs: discard (hole punch) support

2013-06-13T21:37:43+00:00

Add support for the DISCARD file operation. Discard punches a hole
in a file in the provided range. Block de-allocation is implemented
via fallocate() (as requested via fuse and passed on to the brick
fs) but a separate fop is created within gluster to emphasize the
fact that discard changes file data (the discarded region is
replaced with zeroes) and must invalidate caches where appropriate.

gluster: add fallocate fop support

2013-06-13T21:37:21+00:00

Implement support for the fallocate file operation. fallocate
allocates blocks for a particular inode such that future writes
to the associated region of the file are guaranteed not to fail
with ENOSPC.

This patch adds fallocate support to the following areas:

	- libglusterfs
	- mount/fuse
	- io-stats
	- performance/md-cache,open-behind
	- quota
	- cluster/afr,dht,stripe
	- rpc/xdr
	- protocol/client,server
	- io-threads
	- marker
	- storage/posix
	- libgfapi

md-cache: support negative xattr entries

2013-05-25T18:35:50+00:00

Add support for negative xattr caching. For this, we need
to fetch xattrs in every opportunity (including readdirplus)
in order to treat missing key in cached dict as negative entry.

This is crucial to detect missing ACL xattrs in Samba workload.

cluster/afr: Avoid self-healing extended attribute used by SELinux.

2013-05-01T03:11:37+00:00

Since removexattr() fails to remove "security.selinux" in a system 
where SELinux is enforcing, xattr self-healing fails. 
As a consequence of this, user extended attributes are not being healed.
Added a check in afr to prune SELinux xattr from the dictionary 
used for removing xattrs from the sink.

Minor changes in tests and md-cache as well.
