* quota: new volume set option to track of quota in GD2Hari Gowtham2018-07-211-0/+10

* performance/read-ahead: stricter adherence to force-atime-updateRaghavendra G2018-07-191-12/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | Throwaway read-ahead cache in fstat only if force-atime-update is set. Note that fstat flushes read-ahead cache only for atime consistency. However if atime consistency is needed user is required to set force-atime-update which updates atime on backend fs even though application reads are served from read-ahead cache. So, if user has not set force-atime-update, atime won't be accurate and there is no point in flushing read-ahead cache in fstats. mounts requiring atime consistency have to mandatorily set force-atime-update. Also note that normally kernel interspers reads with fstat. So, read-ahead is not effective as fstats flush read-ahead-cache. Instead it regresses performance due to wasted network reads. It is recommended to turn off read-ahead if applications require atime consistency. This patch is aimed at applications which don't require atime consistency. Without atime consistency required, read-ahead cache is effective and increases performance of sequential reads.

* posix: check before removing stale symlinkRavishankar N2018-07-191-4/+8
| | | | | | | | | | | | | | BZ 1564071 complains of directories with missing gfid symlinks and corresponding "Found stale gfid handle" messages in the logs. Hence add a check to see if the symlink points to an actual directory before removing it. Note: Removing stale symlinks was added via commit 3e9a9c029fac359477fb26d9cc7803749ba038b2 Change-Id: I5d91fab8e5f3a621a9ecad4a1f9c898a3c2d346a Updates: bz#1564071 Signed-off-by: Ravishankar N <ravishankar@redhat.com>
* cluster/dht: Set loc->gfid before healing attrN Balachandran2018-07-181-1/+2
| | | | | | | | | | | | | AFR takes inodelks when setting attrs. The loc->gfid and loc->inode->gfid were both null when dht_dir_attr_heal was called during a fresh lookup of an existing directory. As the gfid is null, client_pre_inodelk asserts in the gfid check. We now set the loc->gfid before calling dht_dir_attr_heal.

* afr: switch lk_owner only when pre-op succeedsRavishankar N2018-07-182-15/+10
| | | | | | | | | | | | | | | | | | | Problem: In a disk full scenario, we take a failure path in afr_transaction_perform_fop() and go to unlock phase. But we change the lk-owner before that, causing unlock to fail. When mount issues another fop that takes locks on that file, it hangs. Fix: Change lk-owner only when we are about to perform the fop phase. Also fix the same issue for arbiters when afr_txn_arbitrate_fop() fails the fop. Also removed the DISK_SPACE_CHECK_AND_GOTO in posix_xattrop. Otherwise truncate to zero will fail pre-op phase with ENOSPC when the user is actually trying to freee up space.

* glusterd: memory leak in get-stateSanju Rakonde2018-07-181-34/+19
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: gluster get-state command is leaking the memory when geo-replication session is configured. Cause: In glusterd_print_gsync_status(), we are trying to get reference to the keys of gsync_dict. The references to keys of gsync_dict are stored status_vols[i]. status_vols[i] are allocated with a memory of size of gf_gsync_status_t. Solution: Need not to use a array of pointers(status_vals), using a pointer to hold the reference to a key of gsync_dict is sufficient. Followed the below steps for testing: 1. Configured geo-rep session 2. Ran gluster get-state command for 1000 times. Without this patch, glusterd's memory was increasing significantly (around 22000KB per 1000 times), with this patch it reduced (1500KB per 1000 times) fixes: bz#1601423 Change-Id: I361f5525d71f821bb345419ccfdc20ca288ca292 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* cluster/afr: Mark dirty for entry transactions for quorum failureskarthik-us2018-07-161-11/+51
| | | | | | | | | | | | | | | | | | Problem: If an entry creation transaction fails on quprum number of bricks it might end up setting the pending changelogs on the file itself on the brick where it got created. But the parent does not have any entry pending marker set. This will lead to the entry not getting healed by the self heal daemon automatically. Fix: For entry transactions mark dirty on the parent if it fails on quorum number of bricks, so that the heal can do conservative merge and entry gets healed by shd.

* server: Set ssl-allow option in options table and rename IDPrashanth Pai2018-07-111-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change explicitly adds 'ssl-allow' options to the server xlator's options table so that glusterd2 can see it as a settable option. This change also marks 'auth.allow' and 'auth.reject' options as a settable. Glusterd2 doesn't maintain a separate volume options table. Glusterd2 dynamically loads shared objects of xlators to read their option table and other information. Glusterd2 reads 'xlator_api_t' if available. If that's not available, it falls back to reading just the options table directly. In glusterd2, volume set operations are performed by users on keys of the format <xlator>.<option-name>. Glusterd2 uses xlator name set in 'xlator_api_t.identifier'. If that's not present it will use the shared object's file name as xlator name. Hence, it is important for 'xlator_api_t.identifier' to be set properly, and in this case, the proper value is "server". This name shall be used by users as prefix while setting volume options implemented in server xlator. The name will also be used in volfile. A user in glusterd2 can authorize a client over TLS as follows: $ glustercli volume set <volname> server.ssl-allow <client1-CN>[,<clientN-CN>] gd2 References: https://github.com/gluster/glusterd2/issues/971 https://github.com/gluster/glusterd2/issues/214 https://github.com/gluster/glusterd2/pull/967 Updates: bz#1193929 Change-Id: I59ef58acb8d51917e6365a83be03e79ae7c5ad17 Signed-off-by: Prashanth Pai <ppai@redhat.com>

* io-stats: Terminate dump thread when dump interval is set to 0ShyamsundarR2018-07-091-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | _ios_dump_thread is not terminated by the function _ios_destroy_dump_thread when the diagnostic interval is set to 0 (which means disable auto dumping). During reconfigure, if the value changes from 0 to another then the thread is started, but on reconfiguring this to 0 the thread is not being terminated. Further, if the value is changed from 0 to X to 0 to Y, where X and Y are 2 arbitrary duration numbers, the reconfigure code ends up starting one more thread (for each change from 0 to a valid interval). This patch fixes the same by terminating the thread when the value changes from non-zero to 0. NOTE: It would seem nicer to use conf->dump_thread and check its value for thread presence etc. but there is no documented invalid value for the same, and hence an invalid check is not feasible, thus introducing a new running bool to determine the same.

| | | | | | | | | | | | | | | | | | | | Problem: gluster get-state command is crashing glusterd process, when geo-replication session is configured.

Before calling dict_unref(), glusterd_print_gsync_status_by_vol is calling glusterd_print_gsync_status(). glusterd_print_gsync_status is freeing up values in the dictionary and again when dict_unref() is called, it tries to free up the values which are already freed.

| | | | | | | | | | | | | | Problem: In the new eager-lock implementation lk-owner is assigned after the 'local' is added to the eager-lock list, so there exists a possibility of lock being sent even before lk-owner is assigned.

* cluster/dht: Do not try to use up the readdirp bufferN Balachandran2018-06-293-53/+66
| | | | | | | | | | | | | | | | | | | | | | | | | DHT attempts to use up the entire buffer in readdirp before unwinding in an attempt to reduce the number of calls. However, this has 2 disadvantages: 1. This can cause a stack overflow when parallel readdir is enabled. If the buffer only has a little space,rda can send back only one or two entries. If those entries are stripped out by dht_readdirp_cbk (linkto files for example) it will once again wind down to rda in an attempt to fill the buffer before unwinding to FUSE. This process can continue for several iterations, causing the stack to grow and eventually overflow, causing the process to crash. 2. If parallel readdir is disabled, dht could send readdirp calls with small buffers to the bricks, thus increasing the number of network calls. We are therefore reverting to the existing behaviour. Please note, this only mitigates the stack overflow, it does not prevent it from happening. This is still possible if a subvol has thousands of linkto files for instance.
