* cluster/afr: Perform delayed changelog wakeups for anon fdPranith Kumar K2013-06-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | Problem: Nfs xlator never does open on a file for performing writes, afr does not perform changelog wakeup for this fd so operations which do metadata operations as soon as the data operations are completed perceive a delay of 'post-op-delay-secs'. Fix: Perform changelog wakeup on anon-fd if the fd with same pid is not present in inode-list. Note: This approach is a short-term fix. A proper fix needs a new domain for taking metadata locks so that data/metadata locks don't compete with each other.

| | | | | | | | | | | | | | | | Currently we have tuple (server-xlator-name, callid) for identifying a call. However it does not uniquely identify the operation when there are multiple clients (since operations from all clients go through same server). Adding connection-id resolves this ambiguity. Also printing connection-id helps diagnose failures associated with connection state (like fds, locks).

* glusterd: Disable transport before cleaning up rpc objectKrishnan Parthasarathi2013-06-183-19/+99
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: rpc_transport object, which is part of rpc_clnt, is destroyed prematurely. This is because, rpc_transport object is ref'd by socket layer and rpc layer. These ref's, until the synctask'izing of operations, were unref'd sequentially in the epoll thread. With more threads at play, the sequential unref guarantee is off. Fix: Shutting down the transport before proceeding with cleaning up of rpc_clnt object would serialize the unref's on the rpc_transport object and thus eliminating the race. Also, we don't store the address of brickinfo in brick's rpc notify function, to avoid the possibility of referring a freed brickinfo. Instead we use a string based id to 'reach' the corresponding brickinfo.

* protocol/rpc: move latest added procedures to the end of the arrayNiels de Vos2013-06-172-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | While looking at the newly introduced procedures FALLOCATE and DISCARD, it seems that these were added with already existing procedure numbers. This makes the protocol incompatible with existing roll-outs. It is very confusing when new procedures are added somewhere in the middle of the array. This will cause the number of existing procedures to change. It is much preferred to add new procedures at the end of the array. This changes not only corrects the enum that generates the procedure numbers, but also the ordering in the client and server fops-array for clarity. Correcting this greatly simplifies adding support for these new procedures in Wireshark and will prevent confusion to the people reading network traces (with or without Wireshark).

* cluster/dht: Linkfiles creation with correct uid/gidshishir gowda2013-05-312-20/+47
| | | | | | | | | | | | | | | | | | | | If renames are done with different uid/gid (non-owners), then we would end up with incorrect uid/gid. The fix is to create linkfiles, and heal the uid/gid as root:root. This preserves our notion of creation as root:root and heal the uid/gid as root:root in all paths. Additionally, we need to consider uid/gid from only src_cached subvol, and not from linkfiles. rename is also done as root:root if done on linkfile, as setattr of ownership on linkfile is done after the rename Change-Id: Icb5d431dc42da9c02dfae81980e3fe769a47a274 BUG: 884597 Signed-off-by: shishir gowda <sgowda@redhat.com> Reviewed-on: http://review.gluster.org/4682 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>

| | | | | | | | | | | | | | | | | | In path based op's like truncate, we use getxattr instead of fgetxattr call. These can fail with permission denied issues as linkto file creation, and setattr of ownership is not atomic, and in cases where setattr failed (subvols down..) The fix is to perform getxattr as root:root as it is a internal fop. fgetxattr, bypass the access check, as it already has a valid open fd.

| | | | | | | | | | | | | | | | | | | | | Problem: Currently when gluster volume start force is executed, client process will talk to glusterd to get the port of the brick. But if brick's path is not available it cannot return brick's port. So client process will keep connecting and disconnecting from glusterd for port-query which is ultimately responsible for execssive logging of disconnect messages. Fix: Message will be logged just once at INFO level after the first disconnect from glusterd. Afterwards "disconnect" messages will be logged in DEBUG mode.

* dht,posix: support for case discoveryAnand Avati2013-05-252-0/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is support for discovering a filename in a given directory which has a case insensitive match of a given name. It is implemented as a virtual extended attribute on the directory where the required filename is specified in the key. E.g: sh# getfattr -e "text" -n user.glusterfs.get_real_filename:FiLe-B /mnt/samba/patchy getfattr: Removing leading '/' from absolute path names # file: mnt/samba/patchy user.glusterfs.get_real_filename:FiLe-B="file-b" In reality, there can be multiple "answers" as the backend filesystem is case sensitive and there can be multiple files which can strcasecamp() successfully. In this case we pick the first matched file from the first responding server. If a matching file does not exist, we return ENOENT (and NOT ENODATA). This way the caller can differentiate between "unsupported" glusterfs API and file not existing. This API is used by Samba VFS to perform efficient discovery of the real filename without doing a full scan at the Samba level.

* glusterd: Give up biglock during rpc conn cleanupKrishnan Parthasarathi2013-05-231-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | glusterd could deadlock after a peer-detach command as follows, 1) glusterd_friend_cleanup function 'flushes' out messages in the rpc layer's queue, that haven't received a response. At this point, glusterd has already acquired the big lock. 2) The side-effect of flushing out the messages is that the corresponding call backs are called. Call backs themselves are executed after acquiring the big lock. This results in the big lock being acquired in a nested manner (in the same thread), which causes a deadlock. This can also happen during brick/NFS/SHD disconnect in volume-stop.
