* cluster/dht: Serialize mds update code path with lookup unwind in selfhealMohit Agrawal2017-11-221-2/+0
| | | | | | | | | | | | | | | | Problem: Sometime test case ./tests/bugs/bug-1371806_1.t is failing on centos due to race condition between fresh lookup and setxattr fop. Solution: In selfheal code path we do save mds on inode_ctx, it was not serialize with lookup unwind. Due to this behavior after lookup unwind if mds is not saved on inode_ctx and if any subsequent setxattr fop call it has failed with ENOENT because no mds has found on inode ctx.To resolve it save mds on inode ctx has been serialize with lookup unwind.

* afr: add checks for allowing lookupsRavishankar N2017-11-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | Problem: In an arbiter volume, lookup was being served from one of the sink bricks (source brick was down). shard uses the iatt values from lookup cbk to calculate the size and block count, which in this case were incorrect values. shard_local_t->last_block was thus initialised to -1, resulting in an infinite while loop in shard_common_resolve_shards(). Fix: Use client quorum logic to allow or fail the lookups from afr if there are no readable subvolumes. So in replica-3 or arbiter vols, if there is no good copy or if quorum is not met, fail lookup with ENOTCONN. With this fix, we are also removing support for quorum-reads xlator option. So if quorum is not met, neither read nor write txns are allowed and we fail the fop with ENOTCONN.

* mount/fuse: use fstat in getattr implementation if any opened fd is availableRaghavendra G2017-11-091-11/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The restriction of using fds opened by the same Pid means fds cannot be shared across threads of multithreaded application. Note that fops from kernel have different Pid for different threads. Imagine following sequence of operations: * Turn off performance.open-behind * Thread t1 opens an fd - fd1 - on file "file". Let's assume nodeid of "file" is "nodeid-file". * Thread t2 does RENAME ("newfile", "file"). Let's assume nodeid of "newfile" as "nodeid-newfile". * t2 proceeds to do fstat (fd1) The above set of operations can sometimes result in ESTALE/ENOENT errors. RENAME overwrites "file" with "newfile" changing its nodeid from "nodeid-file" to "nodeid-newfile" and post RENAME, "nodeid-file" is removed from the backend. If fstat carries nodeid-file as argument, which can happen if lookup has not refreshed the nodeid of "file" and since t2 doesn't have an fd opened, fuse_getattr_resume uses STAT which will fail as "nodeid-file" no longer exists. Since the above set of operations and sharing of fds across multiple threads are valid, this is a bug. The fix is to use any fd opened on the inode. In this specific example fuse_getattr_resume will find fd1 and winds down the call as fstat (fd1) which won't fail. Cross-checked with "Miklos Szeredi" <mszeredi.at.redhat.dot.com> for any security issues with this solution and he approves the solution. Thanks to "Miklos Szeredi" <mszeredi.at.redhat.dot.com> for all the pointers and discussions.

* cluster/afr: Fail open on split-brainPranith Kumar K2017-10-261-0/+1
| | | | | | | | | | | | | | | | | Problem: Append on a file with split-brain succeeds. Open is intercepted by open-behind, when write comes on the file, open-behind does open+write. Open succeeds because afr doesn't fail it. Then write succeeds because write-behind intercepts it. Flush is also intercepted by write-behind, so the application never gets to know that the write failed. Fix: Fail open on split-brain, so that when open-behind does open+write open fails which leads to write failure. Application will know about this failure.

* snapshot: Issue with other processes accessing the mounted brickSunny Kumar2017-10-232-0/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added code for unmount of activated snapshot brick during snapshot deactivation process which make sense as mount point for deactivated bricks should not exist. Removed code for mounting newly created snapshot, as newly created snapshots should not mount until it is activated. Added code for mount point creation and snapshot mount during snapshot activation. Added validation during glusterd init for mounting only those snapshot whose status is either STARTED or RESTORED. During snapshot restore, mount point for stopped snap should exist as it is required to set extended attribute. During handshake, after getting updates from friend mount point for activated snapshot should exist and should not for deactivated snapshot. While getting snap status we should show relevent information for deactivated snapshots, after this pathch 'gluster snap status' command will show output like- Snap Name : snap1 Snap UUID : snap-uuid Brick Path : server1:/run/gluster/snaps/snap-vol-name/brick Volume Group : N/A (Deactivated Snapshot) Brick Running : No Brick PID : N/A Data Percentage : N/A LV Size : N/A Fixes: #276 Change-Id: I65783488e35fac43632615ce1b8ff7b8e84834dc BUG: 1482023 Signed-off-by: Sunny Kumar <sunkumar@redhat.com>
* glusterd:Marking all the brick status as stopped when a process goes down in ↵Sanju Rakonde2017-10-121-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | brick multiplexing In brick multiplexing environment, if a brick process goes down i.e., if we kill it with SIGKILL, the status of the brick for which the process came up for the first time is only changing to stopped. all other brick statuses are remain started. This is happening because the process was killed abruptly using SIGKILL signal and signal handler wasn't invoked and further cleanup wasn't triggered. When we try to start a volume using force, it shows error saying "Request timed out", since all the brickinfo->status are still in started state, we're waiting for one of the brick process to come up which never going to happen since the brick process was killed. To resolve this, In the disconnect event, We are checking all the processes that whether the brick which got disconnected belongs the process. Once we get the process we are calling a function named glusterd_mark_bricks_stopped_by_proc() and sending brick_proc_t object as an argument. From the glusterd_brick_proc_t we can get all the bricks attached to that process. but these are duplicated ones. To get the original brickinfo we are reading volinfo from brick. In volinfo we will have original brickinfo copies. We are changing brickinfo->status to stopped for all the bricks.

* glusterd : fix client io-threads option for replicate volumesRavishankar N2017-10-091-0/+48
| | | | | | | | | | | | | | | | | | | Problem: Commit ff075a3d6f9b142911d25c27fd209838782bfff0 disabled loading client-io-threads for replicate volumes (it was set to on by default in commit e068c1997314046658dd502e9118dab32decf879) due to performance issues but in doing so, inadvertently failed to load the xlator even if the user explicitly enabled the option using the volume set command. This was despite returning returning sucess for the volume set. Fix: Modify the check in perfxl_option_handler() and add checks in volume create/add-brick/remove-brick code paths, tying it all to GD_OP_VERSION_3_12_2.

* afr: heal gfid as a part of entry healRavishankar N2017-10-091-0/+68
| | | | | | | | | | | | | | | | | | Problem: If a brick crashes after an entry (file or dir) is created but before gfid is assigned, the good bricks will have pending entry heal xattrs but the heal won't complete because afr_selfheal_recreate_entry() tries to create the entry again and it fails with EEXIST. Fix: We could have fixed posx_mknod/mkdir etc to assign the gfid if the file already exists but the right thing to do seems to be to trigger a lookup on the bad brick and let it heal the gfid instead of winding an mknod/mkdir in the first place.

* cluster/dht : User xattrs are not healed after brick stop/startMohit Agrawal2017-10-047-19/+352
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In a distributed volume custom extended attribute value for a directory does not display correct value after stop/start or added newly brick. If any extended(acl) attribute value is set for a directory after stop/added the brick the attribute(user|acl|quota) value is not updated on brick after start the brick. Solution: First store hashed subvol or subvol(has internal xattr) on inode ctx and consider it as a MDS subvol.At the time of update custom xattr (user,quota,acl, selinux) on directory first check the mds from inode ctx, if mds is not present on inode ctx then throw EINVAL error to application otherwise set xattr on MDS subvol with internal xattr value of -1 and then try to update the attribute on other non MDS volumes also.If mds subvol is down in that case throw an error "Transport endpoint is not connected". In dht_dir_lookup_cbk| dht_revalidate_cbk|dht_discover_complete call dht_call_dir_xattr_heal to heal custom extended attribute. In case of gnfs server if hashed subvol has not found based on loc then wind a call on all subvol to update xattr. Fix: 1) Save MDS subvol on inode ctx 2) Check if mds subvol is present on inode ctx 3) If mds subvol is down then call unwind with error ENOTCONN and if it is up then set new xattr "GF_DHT_XATTR_MDS" to -1 and wind a call on other subvol. 4) If setxattr fop is successful on non-mds subvol then increment the value of internal xattr to +1 5) At the time of directory_lookup check the value of new xattr GF_DHT_XATTR_MDS 6) If value is not 0 in dht_lookup_dir_cbk(other cbk) functions then call heal function to heal user xattr 7) syncop_setxattr on hashed_subvol to reset the value of xattr to 0 if heal is successful on all subvol. Test : To reproduce the issue followed below steps 1) Create a distributed volume and create mount point 2) Create some directory from mount point mkdir tmp{1..5} 3) Kill any one brick from the volume 4) Set extended attribute from mount point on directory setfattr -n user.foo -v "abc" ./tmp{1..5} It will throw error " Transport End point is not connected " for those hashed subvol is down 5) Start volume with force option to start brick process 6) Execute getfattr command on mount point for directory 7) Check extended attribute on brick getfattr -n user.foo <volume-location>/tmp{1..5} It shows correct value for directories for those xattr fop were executed successfully. Note: The patch will resolve xattr healing problem only for fuse mount not for nfs mount.

* afr: auto-resolve split-brains for zero-byte filesRavishankar N2017-09-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Problems: As described in BZ 1491670, renaming hardlinks can result in data/mdata split-brain of the DHT link-to files (T files) without any mismatch of data and metadata. As described in BZ 1486063, for a zero-byte file with only dirty bits set, arbiter brick will likely be chosen as the source brick. Fix: For zero byte files in split-brain, pick first brick as a) data source if file size is zero on all bricks. b) metadata source if metadata is the same on all bricks In arbiter case, if file size is zero on all bricks and there are no pending afr xattrs, pick 1st brick as data source.

* md-cache: avoid checking the xattr value buffer with string functions.Günther Deschner2017-08-011-0/+27
| | | | | | | | | | | | | | | | | | | | | | | xattrs may very well contain binary, non-text data with leading 0 values. Using strcmp for checking empty values is not the appropriate thing to do: In the best case, it might treat a binary xattr value starting with 0 from being cached (and hence also from being reported back with xattr). In the worst case, we might read beyond the end of a data blob that does contain any zero byte. We fix this by checking the length of the data blob and checking the first byte against 0 if the length is one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces a new global option that can be set to limit the number of multiplexed bricks in one process. Usage: `# gluster volume set all cluster.max-bricks-per-process <value>` If this option is not set then multiplexing will happen for now with no limitations set; i.e. a brick process will have as many bricks multiplexed to it as possible. In other words the current multiplexing behaviour won't change if this option isn't set to any value. This commit also introduces a brick process instance that contains information about brick processes, like the number of bricks handled by the process (which is 1 in non-multiplexing cases), list of bricks, and port number which also serves as an unique identifier for each brick process instance. The brick process list is maintained in 'glusterd_conf_t'.

* features/shard: Remove ctx from LRU in shard_forgetPranith Kumar K2017-06-301-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: There is a race when the following two commands are executed on the mount in parallel from two different terminals on a sharded volume, which leads to use-after-free. Terminal-1: while true; do dd if=/dev/zero of=file1 bs=1M count=4; done Terminal-2: while true; do cat file1 > /dev/null; done In the normal case this is the life-cycle of a shard-inode 1) Shard is added to LRU when it is first looked-up 2) For every operation on the shard it is moved up in LRU 3) When "unlink of the shard"/"LRU limit is hit" happens it is removed from LRU But we are seeing a race where the inode stays in Shard LRU even after it is forgotten which leads to Use-after-free and then some memory-corruptions. These are the steps: 1) Shard is added to LRU when it is first looked-up 2) For every operation on the shard it is moved up in LRU Reader-handler Truncate-handler 1) Reader handler needs shard-x to be read. 1) Truncate has just deleted shard-x 2) In shard_common_resolve_shards(), it does inode_resolve() and that leads to a hit in LRU, so it is going to call __shard_update_shards_inode_list() to move the inode to top of LRU 2) shard-x gets unlinked from the itable and inode_forget(inode, 0) is called to make sure the inode can be purged upon last unref 3) when __shard_update_shards_inode_list() is called it finds that the inode is not in LRU so it adds it back to the LRU-list Both these operations complete and call inode_unref(shard-x) which leads to the inode getting freed and forgotten, even when it is in Shard LRU list. When more inodes are added to LRU, use-after-free will happen and it leads to undefined behaviors. Fix: I see that the inode can be removed from LRU even by the protocol layers like gfapi/gNFS when LRU limit is reached. So it is better to add a check in shard_forget() to remove itself from LRU list if it exists.
