* cluster/afr: Filter O_TRUNC in afr-fix-openPranith Kumar K2012-07-251-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | RCA: When open was done while a brick is down, afr opens the file after the brick comes backup. If this happens after the self-heal on the file is completed by self-heald etc, the file will end up in truncated state. Fix: Filter O_TRUNC while afr-fix-open because afr_open turns O_TRUNC into truncate transaction, so there will be pending changelog for the subvolume on which open fails. Testing: Had to simulate the race by stopping fix-open until self-heald completes self-heal on the file after brick online.

| | | | | | | | | | | | | | | Write-behind returns write requests immediately and queues the request in memory for merging, etc. If a write is incomplete, pend an EIO error for the next fop.

* cluster: fix crash on link of named pipe in stripe/replicate volBrian Foster2012-07-252-12/+11
| | | | | | | | | | | | | | | | | | | | | | | | A crash occurs when attempting to link a named pipe on a striped, replicated volume. The cause for this crash is attempting to deref a NULL inode pointer in stripe_link_cbk(). The RCA for this bug uncovered a couple of problems: - AFR ignores the inode pointer it receives on failure (returning NULL). - stripe assumes the inode pointer is valid on failure. Either one of these changes addresses the crash, but this patch includes both changes. AFR is modified to pass along the inode pointer it receives (which could still be NULL). stripe is modified to not assume the inode pointer is valid on fop failure.

* libglusterfs: fix creation of spurious root inodesRaghavendra Bhat2012-07-241-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Suppose lookup is sent on a newly created inode (gfid is root gfid), and in the call back inode_link is done, where if there is an inode already present in the inode table for that gfid, then we start using the present inode and the newly created inode supposedly gets destroyed when refcount comes down to zero through inode_unref calls. But inodes with root gfid are not unrefed. Now since in inode_link, the gfid has already been copied to the new inode and later the actual inode is found from the inode table, the new inode does not gets unrefed if its gfid is root gfid. Thus those spurious inodes with root gfid will be present throughout the lifetime of the filesystem. To fix this first search the inode table for an inode, with the gfid, present in the stat structure received as an argument. If the inode is not found, then copy the gfid to the newly created inode. Now whenever unref is called on on the new inode it gets unrefed and thus eventually gets destroyed Change-Id: I0f25f0a8dca3245abda1c322c216f063b52cf842 BUG: 841188 Signed-off-by: Raghavendra Bhat <raghavendra@redhat.com> Reviewed-on: http://review.gluster.com/3716 Reviewed-by: Amar Tumballi <amarts@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
* Fixes for gsyncd / geo-rep and FUSE listxattrVenky Shankar2012-07-242-8/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes two problems with recent changes to Geo-Replication First: ------ Recent changes to geo-replication relies on Rsync to tranfer extended attributes. Essentially Rsync would invoke a listxattr() and then getxattr() the set reutrned by listxattr() and finally transfer it to the remote slave. Xattrs like security.selinux would create problems as they are not allowed to be set explicitly (unless there's a rule that allows this). So, to make Rsync behave sanely we filter out all "*.selinux*" xattrs from listxattr() (which is getxattr() with ->name as NULL). Second: ------- Python's "if {..} else {..}" shortcut ".. and .. or .." was misused here. This is a straightforward fix by interchanging last two variables (classes in this case). Also fix a typo in sendmark_regular() definition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Context ------- gsyncd/geo-rep plans to rely on Rsync to sync extended attributes. When this is in place, all xattrs *visible* on the mount point would be candidate for syncing. This set could include gluster internal xattrs too (as xome xlators do not filter out in their cbks). Syncing these xattrs to the slave could result in unexpected functioning of the slave mount. Soln. ----- For gsyncd auxillary mounts (identified by client_pid -1), we only allow xtime related xattrs to go through and silently ignore (w/o propagating error back to the client) the rest of them. This provides a future proof solution as we need not worry about what xattrs show up on the mounts. Also, 'user' namespace xattrs are always passed through even if it's from a gsyncd aux mount.

There are two approaches to building a libgfapi based application: 1. In the presence of pkg-config in your build system. This is the recommended approach which is also used in this example. For this approach to work, you need to build glusterfs by passing --pkgconfigdir=/usr/lib64/pkgconfig (or the appropriate directory) in your distro. This already happens if you build RPMs with the glusterfs.spec provided in glusterfs.git. You will also need to install glusterfs-api RPM. 2. In the absence of pkg-config in your build system.

* glusterfs_ctx_t: un-globalize the filesystem contextAnand Avati2012-07-1720-133/+121
| | | | | | | | | | | | | | | | | | | | | | | | So far there has been a global glusterfs_ctx_t object which represents the running instance of the filesystem (client or server). It contains the various graphs, connection to the management daemon over which new graphs are obtained, calls stacks issued on this filesystem, and a bunch of such things. With the introduction of libgfapi, it is no more true that there will be only one filesystem context in a process. Applications can be written to use libgfapi and obtain serveral instances of different filesystems/volumes in the same process. This involves messy untangling of assumptions inside libglusterfs that there would only be one global glusterfs_ctx_t and offload that assumption to glusterfsd/ and cli/ (where it is true).

* libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridgeBrian Foster2012-07-1714-120/+353
| | | | | | | | | | | | | | | | | | | | | | | | | | This change genericizes the cache mechanism implemented in commit 8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as a client. The cache mechanism is fundamentally equivalent, with some minor changes: - Change cache key from uid_t to uint64_t. - Modify the cache add logic to locate and use an entry with a matching ID, should it already exist. This addresses a bug in the existing mechanism where an expired entry supercedes a newly added entry in lookup, causing repeated adds and flushing of a cache bucket. The fuse group cache is disabled by default. It can be enabled via the 'gid-timeout' fuse-bridge translator option and accompanying mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).
