* extras/checkpatch.pl: linux kernel style patch verificationHarshavardhana2014-09-182-4/+4427
| | | | | | | | | | | | | | | | | | | | | | | | | | This is to bring in adherence to coding policy, prior to patch submission for review. - no tabs - no whitespace - indentation (linux style) etc. This is in the interest at large for the GlusterFS codebase to be more cleaner and readable. ./rfc.sh - now supports running this for all patches diverged from "origin/master" revision. NOTE: One should take this as a handle for good guidelines and never use it as a tool for correctness, use common-sense in all the cases ;-) Change-Id: Ib9a5ed207cde152cb92b8d38cec83e8ce9ef7f28 BUG: 1120646 Signed-off-by: Harshavardhana <harsha@harshavardhana.net> Reviewed-on: http://review.gluster.org/8181 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anders Blomdell <anders.blomdell@control.lth.se>
* storage/posix: Log when mkdir is on an existing gfid but non-existentRaghavendra G2014-09-181-1/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | path. consider following steps on a distribute volume 1. rename (src, dst) on hashed subvolume 2. snapshot taken 3. restore snapshots and do stat on src and dst Now, we end up with two directories src and dst having same gfid, because of distribute creating directories on non-existent subvolumes as part of directory healing. This can happen even with race between rename and directory healing in dht-lookup. This can lead to undefined behaviour while accessing any of both directories. Hence, we are logging paths of both directories, so that a sysadmin can take some corrective action when (s)he sees this log. One of the corrective action can be to copy contents of both directories from backend into a new directory and delete both directories. Since effort involved to fix this issue is non-trivial, giving this workaround till we come up with a fix.

* snapview-server: get the handle if its absent before doing any fopRaghavendra Bhat2014-09-123-34/+177
| | | | | | | | | | | | | | | | | | | | | | | * Now that NFS server does inode linking in readdirp, it can resolve the gfid (i.e. find the right inode from its inode table) present in the filehandle sent by the NFS client on which a fop came. So instead of sending the lookup on that entry, it directly sends the fop. But snapview-server does not get the handle for the entries in readdirp (because doing a lookup on each entry via gfapi would be costly. So it waits till a lookup is done on that inode, to get the handle and the fs instance and fill it in the inode context). So when NFS resoves the gfid and directly sends the fop, snapview-server will not be able to perform the fop as the inode contet would not contain the fs instance and the handle. So fops should check for the handle before doing gfapi calls. If the handle and fs instance are not present in the inode context they should get them by doing an explicit lookup on the entry.

| | | | | | | | | | | | | | | | | | | | | | | | | This patch implements the Galois Field multiplications using pure C code without any assembler support. This makes the ec xlator portable to other architectures. In the future it will be possible to use an optimized implementation of the multiplications using architecture dependent facilities (it will be automatically detected and configured). To allow bricks with different machine word sizes to be able to work seamlessly in the same volume, the minimum fragment length to be stored in any brick has been fixed to 512 bytes. Otherwise, different implementations will corrupt the data (SSE2 used 128 bytes, while new implementation would have used 64). This patch also removes the '-msse2' option added on patch http://review.gluster.org/8395/ Change-Id: Iaf6e4ef3dcfda6c68f48f16ca46fc4fb61a215f4 BUG: 1125166 Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> Reviewed-on: http://review.gluster.org/8413 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com>

| | | | | | | | | | | | | | | | | Glusterd will prevent rebalance from starting when clients older than glusterfs-v3.6.0 are connected to a volume. This is needed as running rebalance with old clients connected could lead to data loss in some cases. The DHT xlator on newer clients (>= 3.6.0) has been fixed to prevent the data loss issues.

As part of same commit, dht_unlink was also changed to accept cached-subvol as part of name. While it makes sense to specify subvol while creating file, there is no necessity for specifying the subvol during unlink, since the default unlink logic works fine with this functionality too. Also, this code in unlink doesn't work well when files get migrated by rebalance process. Hence removing it.

Hence when one client wins the link race, and the other still deletes the linkto file, the rename failure by the winning client is not a critical failure, hence it resolves the issue posted in the bug. As a result modifying the test case to treat the rename failures as errors, to catch any future issues.

* cluster/dht: Rename should not fail post hardlink creationShyam2014-09-022-41/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | In the rename path, we wind the creation of newname hardlink and linkto file in dst hashed a the same time. If the linkto creation fails, but the link creation succeeds, we enter the failure code and cleanup the created newname hardlink. In the interim if another client looks up newname and finds it as a hardlink from FUSE, it could send an unlink for oldname instead of a rename. This combined with the above cleanup code could end up losing all the files copies, and thereby losing data. This fix separates these steps into 2 parts, creating the linkto first and then the link file, so that post link file creation no failures would cleanup the newname file. If linkto fails then link is not attempted, thereby not polluting the name space with newname.
