* cluster/afr: Prioritize ENOSPC over other errorskarthik-us2020-06-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Problem: In a replicate/arbiter volume if file creations or writes fails on quorum number of bricks and on one brick it is due to ENOSPC and on other brick it fails for a different reason, it may fail with errors other than ENOSPC in some cases. Fix: Prioritize ENOSPC over other lesser priority errors and do not set op_errno in posix_gfid_set if op_ret is 0 to avoid receiving any error_no which can be misinterpreted by __afr_dir_write_finalize(). Also removing the function afr_has_arbiter_fop_cbk_quorum() which might consider a successful reply form a single brick as quorum success in some cases, whereas we always need fop to be successful on quorum number of bricks in arbiter configuration.

* posix: fix GF_VALIDATE_OR_GOTO(this->name, this, out)Sanju Rakonde2020-04-161-3/+1
| | | | | | | | | | | | | | | Remove GF_VALIDATE_OR_GOTO(this->name, this, out) when this is passed as an argument and is checked for NULL in the caller itself. GF_VALIDATE_OR_GOTO(this->name, this, out) is modified to use xlator name instead of this->name as we are still verifying whether this is NULL. updates: #1000 Change-Id: Ide3180da29d0d4a35b2c5b9a7604fdf2ff4a9ffb Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* dht - fixing a permission update issueBarak Sason Rofman2020-04-081-10/+6
| | | | | | | | | | | | | | | | | | When bringing back a downed brick and performing lookup from the client side, the permission on said brick aren't updated on the first lookup, but only on the second. This patch modifies permission update logic so the first lookup will trigger a permission update on the downed brick. LIMITATIONS OF THE PATCH: As the choice of source depends on whether the directory has layout or not. Even the directories on the newly added brick will have layout xattr[zeroed], but the same is not true for a root directory. Hence, in case in the entire cluster only the newly added bricks are up [and others are down], then any change in permission during this time will be overwritten by the older permissions when the cluster is restarted. fixes: #999 Change-Id: Ieb70246d41e59f9cae9f70bc203627a433dfbd33 Signed-off-by: Barak Sason Rofman <bsasonro@redhat.com>
* Posix: Optimize posix code to improve file creationMohit Agrawal2020-04-065-74/+220
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Before executing a fop in POSIX xlator it builds an internal path based on GFID.To validate the path it call's (l)stat system call and while .glusterfs is heavily loaded kernel takes time to lookup inode and due to that performance drops Solution: In this patch we followed two ways to improve the performance. 1) Keep open fd specific to first level directory(gfid[0]) in .glusterfs, it would force to kernel keep the inodes from all those files in cache. In case of memory pressure kernel won't uncache first level inodes. We need to open 256 fd's per brick to access the entry faster. 2) Use at based call's to access relative path to reduce path based lookup time. Note: To verify the patch we have executed kernel untar 100 times on 6 different clients after enabling metadata group-cache and some other option.We were getting more than 20 percent improvement in kenel untar after applying the patch.

* Posix: Use simple approach to close fdMohit Agrawal2020-03-204-127/+6
| | | | | | | | | | | | | | | Problem: posix_release(dir) functions add the fd's into a ctx->janitor_fds and janitor thread closes the fd's.In brick_mux environment it is difficult to handle race condition in janitor threads because brick spawns a single janitor thread for all bricks.

| | | | | | | | | | | | | | | | | Problem: With lookup-optimize set to on by default, a client with stale-layout can create a new file on a wrong subvol. This will lead to possible duplicate files if two different clients attempt to create the same file with two different layouts.

| | | | | | | | | | | | When using inode_ctx_get() or inode_ctx_set(), a 'uint64_t *' is expected. In many cases, the value to retrieve or store is a pointer, which will be of smaller size in some architectures (for example 32-bits). In this case, directly passing the address of the pointer casted to an 'uint64_t *' is wrong and can cause memory corruption.

| | | | | | | | | | | | | | | | posix_xattr_fill() is called from several POSIX functions. Made minor changes to it and the functions called from it: 1.

I've looked for additional cases for such an issue and did not find them, luckily.

* protocol/handshake: pass volume-id for extra checkAmar Tumballi2019-09-301-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With added check of volume-id during handshake, we can be sure to not connect with a brick if this gets re-used in another volume. This prevents any accidental issues which can happen with a stale client process lurking along. Also added test case for testing same volume name which would fetch a different volfile (ie, different bricks, different type), and a different volume name, but same brick. For reference: Currently a client<->server handshake happens in glusterfs through protocol/client translator (setvolume) to protocol/server using a dictionary which containes many keys. Rejection happens in server side if some of the required keys are missing in handshake dictionary. Till now, there was no single unique identifier to validate for a client to tell server if it is actually talking to a corresponding server. All we look in protocol/client is a key called 'remote-subvolume', which should match with a subvolume name in server volume file, and for any volume with same brick name (can be present in same cluster due to recreate), it would be same. This could cause major issue, when a client was connected to a given brick, in one volume would be connected to another volume's brick if its re-created/re-used. To prevent this behavior, we are now passing along 'volume-id' in handshake, which would be preserved for the life of client process, which can prevent this accidental connections. NOTE: This behavior wouldn't be applicable for user-snapshot enabled volumes, as snapshotted volume's would have different volume-id.

| | | | | | | | | In various places, we can re-use knowledge of string length or result of snprintf() and such instead of strlen(). Change-Id: I4c9b1decf1169b3f8ac83699a0afbd7c38fad746 updates: bz#1193929 Signed-off-by: Yaniv Kaul <ykaul@redhat.com>

| | | | | | | | | | | | | Problem: Sometime brick is going down to health check thread is failed without logging error codes return by aio system calls. As per aio_error man page it returns a positive error number if the asynchronous I/O operation failed.

* posix: In brick_mux brick is crashed while start/stop volume in loopMohit Agrawal2019-08-203-1/+58
| | | | | | | | | | | | | | | Problem: In brick_mux environment sometime brick is crashed while volume stop/start in a loop.Brick is crashed in janitor task at the time of accessing priv.If posix priv is cleaned up before call janitor task then janitor task is crashed. Solution: To avoid the crash in brick_mux environment introduce a new flag janitor_task_stop in posix_private and before send CHILD_DOWN event wait for update the flag by janitor_task_done Change-Id: Id9fa5d183a463b2b682774ab5cb9868357d139a4 fixes: bz#1730409 Signed-off-by: Mohit Agrawal <moagrawal@redhat.com>

* libglusterfs: remove dependency of rpcAmar Tumballi2019-08-161-1/+0
| | | | | | | | | | | | | | | | | | Goal: 'libglusterfs' files shouldn't have any dependency outside of the tree, specially the header files, shouldn't have '#include' from outside the tree. Fixes: * Had to introduce libglusterd so, methods and structures required for only mgmt/glusterd, and cli/ are separated from 'libglusterfs/' * Remove rpc/xdr/gen from build, which was used mainly so dependency for libglusterfs could be properly satisfied. * Move rpcsvc_auth_data to client_t.h, so all dependencies could be handled.

* features/utime: always update ctime at setattrKinglong Mee2019-08-061-1/+1
| | | | | | | | | | | | | | | | | | | | For the nfs EXCLUSIVE mode create may sets a later time to mtime (at verifier), it should not set to ctime for storage.ctime does not allowed set ctime to a earlier time. /* Earlier, mdata was updated only if the existing time is less * than the time to be updated. This would fail the scenarios * where mtime can be set to any time using the syscall. Hence * just updating without comparison. But the ctime is not * allowed to changed to older date. */ According to kernel's setattr, always set ctime at setattr, and doesnot set ctime from mtime at storage.ctime.
