* dht-shared.c: minor reduction of work under lock.Yaniv Kaul2019-02-141-6/+7
| | | | | | | | | | Minor changes to reduce work done under a lock. Compile-tested only! updates: bz#1193929 Signed-off-by: Yaniv Kaul <ykaul@redhat.com> Change-Id: Ia58adfb5125129e5d1f3bbf2202f38520fdbc29f
* 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. Fix: Update the layout information correctly and reduce the call count only after processing the response.

* cluster/dht: Do not use gfid-req in fresh lookupN Balachandran2019-02-022-8/+60
| | | | | | | | | | | | Fuse sets a random gfid-req value for a fresh lookup. Posix lookup will set this gfid on entries with missing gfids causing a GFID mismatch for directories. DHT will now ignore the Fuse provided gfid-req and use the GFID returned from other subvols to heal the missing gfid.

* core: make gf_thread_create() easier to useXavi Hernandez2019-02-011-6/+1
| | | | | | | | | | | | | | This patch creates a specific function to set the thread name using a string format and a variable argument list, like printf(). This function is used to set the thread name from gf_thread_create(), which now accepts a variable argument list to create the full name. It's not necessary anymore to use a local array to build the name of the thread. This is done automatically.

* 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.

* Multiple files: reduce work while under lock.Yaniv Kaul2019-01-297-95/+92
| | | | | | | | | | | | | | | | | Mostly, unlock before logging. 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.

| | | | | | | | | | | | | | | | | | | | In a previous patch (https://review.gluster.org/20769) we've added the key length to be passed to dict_* funcs, to remove the need to strlen() it. This patch moves some xlators to use it. - In some cases, moved strlen() of the key length outside of locks, which is usually a good thing. Please verify it's safe to do so. - In some cases, created a prefix for the keys, replacing something like "%d-%d" with a "%s" in snprintf(). Not sure it adds value, but improves readability. Please review carefully. Compile-tested only! Change-Id: I04f2a1eb2ecfc3283d849d150d10d088ae7aa7f1 updates: bz#1193929 Signed-off-by: Yaniv Kaul <ykaul@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.

* all: fix the format string exceptionsAmar Tumballi2018-11-053-12/+12
| | | | | | | | | | | | | | | | Currently, there are possibilities in few places, where a user-controlled (like filename, program parameter etc) string can be passed as 'fmt' for printf(), which can lead to segfault, if the user's string contains '%s', '%d' in it. While fixing it, makes sense to make the explicit check for such issues across the codebase, by making the format call properly.

* cluster/ec: prevent infinite loop in self-heal fullXavi Hernandez2018-10-311-5/+6
| | | | | | | | | | | | | | | | | | | | | | | There was a problem in commit 7f81067 that caused infinite loop when full heal was triggered. The previous commit was made to prevent self-heal to go idle after a replace brick operation. One of the changes consisted on setting a flag to force an immediate scan of the dirty directory if a heal on a directory succeeded (assuming it could have generated newer entries). However that change was causing an issue with a full self-heal, since every time an already healed directory was checked and it returned suceessfully, it was also setting the flag, forcing self-heal to start over again. This patch fixes this issue by only setting the flag if the heal is not full. It's assumed that a full self-heal will already traverse all entries automatically, so there's no need to force a new scan later.
