* cluster/ec: Don't enqueue an entry if it is already healingAshish Pandey2019-03-275-30/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: 1 - heal-wait-qlength is by default 128. If shd is disabled and we need to heal files, client side heal is needed. If we access these files that will trigger the heal. However, it has been observed that a file will be enqueued multiple times in the heal wait queue, which in turn causes queue to be filled and prevent other files to be enqueued. 2 - While a file is going through healing and a write fop from mount comes on that file, it sends write on all the bricks including healing one. At the end it updates version and size on all the bricks. However, it does not unset dirty flag on all the bricks, even if this write fop was successful on all the bricks. After healing completion this dirty flag remain set and never gets cleaned up if SHD is disabled. Solution: 1 - If an entry is already in queue or going through heal process, don't enqueue next client side request to heal the same file. 2 - Unset dirty on all the bricks at the end if fop has succeeded on all the bricks even if some of the bricks are going through heal.

* cluster/afr: Send truncate on arbiter brick from SHDkarthik-us2019-03-111-15/+13
| | | | | | | | | | | | | | | | | | | Problem: In an arbiter volume configuration SHD will not send any writes onto the arbiter brick even if there is data pending marker for the arbiter brick. If we have a arbiter setup on the geo-rep master and there are data pending markers for the files on arbiter brick, SHD will not mark any data changelog during healing. While syncing the data from master to slave, if the arbiter-brick is considered as ACTIVE, then there is a chance that slave will miss out some data. If the arbiter brick is being newly added or replaced there is a chance of slave missing all the data during sync. Fix: If there is data pending marker for the arbiter brick, send truncate on the arbiter brick during heal, so that it will record truncate as the data transaction in changelog.

* cluster/afr: Add quorum checks to open & opendir fopskarthik-us2019-03-084-2/+48
| | | | | | | | | | | | | | | Problem: Currently even if open & opendir fails on quorum number of bricks, but succeeds on atleast one brick, it will result in success. This leads to inconsistency in the behaviour with other operations following the open, which has quorum checks. Fix: Add quorum checks to open & opendir fops to avoid inconsistency.

* cluster/dht: Request linkto xattrs in dht_rmdir opendirN Balachandran2019-02-131-1/+26
| | | | | | | | | | | | | | | | | | If parallel-readdir is enabled, the rda xlator is loaded below dht in the graph and proactively lists and caches entries when an opendir is performed. dht_rmdir checks if the directory being deleted contains stale linkto files by performing a readdirp on its child subvols. However, as the entries are actually read in during the opendir operation which does not request the linkto xattr,no linkto xattrs are present for the entries causing dht to incorrectly identify them as data files and fail the rmdir operation with ENOTEMPTY. DHT now always adds the linkto xattr in the list of xattrs requested in the opendir.

* cluster/dht: Fix lookup selfheal and rmdir raceN Balachandran2019-02-131-9/+25
| | | | | | | | | | | | | | A race between the lookup selfheal and rmdir can cause directories to be healed only on non-hashed subvols. This can prevent the directory from being listed from the mount point and in turn causes rm -rf to fail with ENOTEMPTY.

* cluster/thin-arbiter: Consider thin-arbiter before marking new entry changelogAshish Pandey2019-02-014-19/+87
| | | | | | | | | | | | | | | | If a fop to create an entry fails on one of the data brick, we mark the pending changelog on the entry on brick for which it was successful. This is done as part of post op phase to make sure that entry gets healed even if it gets renamed to some other path where its parent was not marked as bad. As it happens as part of post op, we should consider thin-arbiter to check if the brick, which was successful, is the good brick or not. This will avoide split brain and other issues.

In some cases, moved different code that was not needed to be under lock (for example, taking time, or malloc'ing) to be executed before taking the lock. Note: logging might be slightly less accurate in order, since it may not be done now under the lock, so order of logs is racy. I think it's a reasonable compromise.

* cluster/afr: Refactor internal locking code to allow multiple inodelksPranith Kumar K2018-12-286-798/+366
| | | | | | | | | | | | | | | | For implementing copy_file_range fop, AFR needs to perform two inodelks in the same transaction. This patch brings in the necessary structure to make it easier to do so. Entry-locks in AFR were already taking multiple entry-locks on different inodes with the respective basenames. This patch extends the logic in inodelks to use the same lockee_t structure. This lead to removal of quite a lot of duplicate code present in afr-lk-common.c as both the locks are doing same things except 'winding' part. updates: #536 Change-Id: Ibfce7e3f260bb27b18645152ec680c33866fe0ae Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

* cluster/afr: Allow lookup on root if it is from ADD_REPLICA_MOUNTkarthik-us2018-12-187-30/+78
| | | | | | | | | | | | | | | | | | | | | Problem: When trying to convert a plain distribute volume to replica-3 or arbiter type it is failing with ENOTCONN error as the lookup on the root will fail as there is no quorum. Fix: Allow lookup on root if it is coming from the ADD_REPLICA_MOUNT which is used while adding bricks to a volume. It will try to set the pending xattrs for the newly added bricks to allow the heal to happen in the right direction and avoid data loss scenarios. Note: This fix will solve the problem of type conversion only in the case where the volume was mounted at least once. The conversion of non mounted volumes will still fail since the dht selfheal tries to set the directory layout will fail as they do that with the PID GF_CLIENT_PID_NO_ROOT_SQUASH set in the frame->root.

* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-0563-214/+214
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* afr: assign gfid during name heal when no 'source' is present.Ravishankar N2018-12-034-52/+52
| | | | | | | | | | | | | | | | | | Problem: If parent dir is in split-brain or has dirty xattrs set, and the file has gfid missing on one of the bricks, then name heal won't assign the gfid. Fix: Use the brick we select the gfid from as the 'source'. Note: Problem was found while trying to debug a split-brain issue on Cynthia Zhou's setup. updates: bz#1637249 Change-Id: Id088d4f0fb017aa35122de426654194e581ed742 Reported-by: Cynthia Zhou <cynthia.zhou@nokia-sbell.com> Signed-off-by: Ravishankar N <ravishankar@redhat.com>

* cluster/dht: sync brick root perms on add brickN Balachandran2018-11-191-16/+9
| | | | | | | | | | | | | | | | | If a single brick is added to the volume and the newly added brick is the first to respond to a dht_revalidate call, its stbuf will not be merged into local->stbuf as the brick does not yet have a layout. The is_permission_different check therefore fails to detect that an attr heal is required as it only considers the stbuf values from existing bricks. To fix this, merge all stbuf values into local->stbuf and use local->prebuf to store the correct directory attributes.

* afr: open_ftruncate_cbk should read fd from local->cont.open structSoumya Koduri2018-11-151-2/+2
| | | | | | | | | | | | afr_open stores the fd as part of its local->cont.open struct but when it calls ftruncate (if open flags contain O_TRUNC), the corresponding cbk function (afr_ open_ftruncate_cbk) is incorrectly referencing uninitialized local->fd. This patch fixes the same. Change-Id: Icbdedbd1b8cfea11d8f41b6e5c4cb4b44d989aba updates: bz#1648687 Signed-off-by: Soumya Koduri <skoduri@redhat.com>
* core: fix strncpy warningsKaleb S. KEITHLE2018-11-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since gcc-8.2.x (fedora-28 or so) gcc has been emitting warnings about buggy use of strncpy. Most uses that gcc warns about in our sources are exactly backwards; the 'limit' or len is the strlen/size of the _source param_, giving exactly zero protection against overruns. (Which was, after all, one of the points of using strncpy in the first place.) IOW, many warnings are about uses that look approximately like this: ... char dest[8]; char src[] = "this is a string longer than eight chars"; ... strncpy (dest, src, sizeof(src)); /* boom */ ... The len/limit should be sizeof(dest). Note: the above example has a definite over-run. In our source the overrun is typically only theoretical (but possibly exploitable.) Also strncpy doesn't null-terminate on truncation; snprintf does; prefer snprintf over strncpy. Mildly surprising that coverity doesn't warn/isn't warning about this.
