| | | | | | | | | | | | | | | | | | | This test was retried once on build https://build.gluster.org/job/regression-on-demand-multiplex/174/ (logs for the first try is not available with this build) Test case was failing in line #47 where it was was checking for the heal count to be 0. Line #51 had passed that means file got the gfid split brain resolved, and both the bricks had same gfids. At line #54 it again failed which checks for the md5sum on both the bricks. At this point the md5sum of the brick where the file got impunged had the md5sum same as the newly created empty file. This means the data heal has not happened for the file. At line #64 enabling granular-entry-heal faild, but without the logs it is not possible to debug this issue.

* tests/quick-read/bug-846240.t: fix a wrong testRaghavendra G2018-08-131-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier this test did following things on M0 and M1 mounted on same volume: 1 create file M0/testfile 2 open an fd on M0/testfile 3 remove the file from M1, M1/testfile 4 echo "data" >> M0/testfile The test expects appending data to M0/testfile to fail. However, redirector ">>" creates a file if it doesn't exist. So, the only reason test succeeded was due to lookup succeeding due to stale stat in md-cache. This hypothesis is verified by two experiments: * Add a sleep of 10 seconds before append operation. md-cache cache expires and lookup fails followed by creation of file and hence append succeeds to new file. * set md-cache timeout to 600 seconds and test never fails even with sleep 10 before append operation. Reason is stale stat in md-cache survives sleep 10. So, the spurious nature of failure was dependent on whether lookup is done when stat is present in md-cache or not. The actual test should've been to write to the fd opened in step 2 above. I've changed the test accordingly. Note that this patch also remounts M0 after initial file creation as open-behind disables opening-behind on witnessing a setattr on the inode and touch involves a setattr. On remount, create operation is not done and hence file is opened-behind. Change-Id: I739f255e0a62ff0024f0824dad3539974955df99 Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Fixes: bz#1615096

* geo-rep: Fix deadlock during worker startKotresh HR2018-08-132-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Analysis: Monitor process spawns monitor threads (one per brick). Each monitor thread, forks worker and agent processes. Each monitor thread, while intializing, updates the monitor status file. It is synchronized using flock. The race is that, some thread can fork worker while other thread opened the status file resulting in holding the reference of fd in worker process. Cause: flock gets unlocked either by specifically unlocking it or by closing all duplicate fds referring to the file. The code was relying on fd close, hence a reference in worker/agent process by fork could cause the deadlock. Fix: 1. flock is unlocked specifically. 2. Also made sure to update status file in approriate places so that the reference is not leaked to worker/agent process. With this fix, both the deadlock and possible fd leaks is solved. fixes: bz#1614799 Change-Id: I0d1ce93072dab07d0dbcc7e779287368cd9f093d Signed-off-by: Kotresh HR <khiremat@redhat.com>
* glusterd: compare friend data within mutexAtin Mukherjee2018-08-133-41/+48
| | | | | | | | | | | | | | | | | | | | | | | During friend handshake if the glusterd receives more than one friend updates, it might very well become possible that two threads would end up working on two different volinfo references and glusterd might end up updating the store with a old volinfo reference. While debugging glusterd crash from validating-server-quorum.t test file from the line-coverage regression the same was observed. Solution is to run glusterd_compare_friend_data under a mutex. Test: As the crash was more visible in the line-coverage run (given lcov does some instrumentation and exposes the races), 6 manual lcov runs were triggered starting from https://build.gluster.org/job/line-coverage/443 to https://build.gluster.org/job/line-coverage/449/ and no crash was observed from validating-server-quorum.t Change-Id: I86fce473a76fd24742d51bf17a685d28b90a8941 Fixes: bz#1603063 Signed-off-by: Atin Mukherjee <amukherj@redhat.com>
* tests: Fix cleanup routine for some mux testsShyamsundarR2018-08-134-10/+7
| | | | | | | | | | | | | | | | | Some of the mux tests, set a trap to catch test exit and call cleanup. This will cause cleanup to be invoked twice in case the test times out, or even otherwise, as include.rc also sets a trap to cleanup on exit (TERM and others). This leads to the tarballs generated on failures for these tests to be empty and does not aid debugging. This patch corrects this pattern across the tests to the more standard cleanup at the end.

| | | | | | | | | | | | | | | | | | | When a test is retried, the cleanup directives overwrite the older tarball with the latest one, thus losing the logs from the failed run. This patch changes run-tests.sh to rename the older tarball when retrying a test, thus preserving the same. The tarball is renamed using a time stamp and optionally a trailing sequence number, in case the test fails within the very second. Although the sequence # is not strictly required as we retry only once, it provides a defence for any future enhancements to the same.

* tests: Set heal-timeout to 5 secondsPranith Kumar K2018-08-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Shd keeps doing heals in a loop until it heals at least one entry in the previous run. A heal is termed successful only if it heals both metadata and entry/data heal i.e. the entry needs to be completely healed by just that healer. In tests/basic/afr/granular-esh/replace-brick.t test, brick-0 is old and brick-1 is new. After replace-brick only root-gfid will be present in brick-0's index 1) shd-thread corresponding to brick-0 does metadata heal, this creates root-gfid in brick-0's 'dirty' index. 2) Both healer threads corresponding to brick-0 and brick-1 now try to heal root-gfid and brick-1 gets the heal-domain lock. brick-0's shd-thread will experience a failure and it goes back to waiting for 10 minutes (cluster.heal-timeout). 3) When brick-1's healer-thread completes healing root-gfid it creates 5 files which create indices in brick-0, so until brick-0 doesn't trigger one more heal, heal won't happen. $HEAL_TIMEOUT is set at 120 seconds, which is lesser than cluster.heal-timeout, so decreasing this to 5 seconds so that the next heal is triggered which will do the heals. fixes bz#1613807 Change-Id: I881133fc28880d8615fbc4558a0dfa0dc63d7798 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
* tests: Increase timeout for mpx restart crash testShyamsundarR2018-08-091-3/+6
| | | | | | | | | | | | | | | | | | | | In lcov based regression testing environments, all tests take more time than what occurs in centos7 regressions. Possibly due to code instrumentation for lcov purposes. Due to this the test, bug-1432542-mpx-restart-crash.t constantly times out. This patch increases the timeout for the same to enable lcov tests to pass on a more regular basis. It was also noted by Nithya that the test at times generated an OOM kill on the regression machines. In order to reduce runtime memory foot print of the tests, FUSE mounts are unmounted as soon as the required test is complete.

* glusterd: more stricter checks of if brick is running in multiplex modeAtin Mukherjee2018-08-091-32/+39
| | | | | | | | | | | | | | | | | | | | | | | While gf_attach () utility can help in detaching a brick instance from the brick process which the kill_brick () function in tests/volume.rc uses it has a caveat which is as follows: 1. It doesn't ensure the respective brick is marked as stopped which glusterd does from glusterd_brick_stop 2. Sometimes if kill_brick () is executed just after a brick stack is up, the mgmt_rpc_notify () can take some time before marking priv->connected to 1 and before it if kill_brick () is executed, brick will fail to initiate the pmap_signout which would inturn cleans up the pidfile. To avoid such possibilities, a more stricter check on if a brick is running or not in brick multiplexing has been brought in now where it not only checks for its pid's existance but checks if the respective process has the brick instance associated with it before checking for brick's status.

* performance/ob: stringent synchronization between rename/unlink and openRaghavendra G2018-08-032-67/+330
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue 1: ======== open all pending fds before resuming rename and unlink currently ob uses fd_lookup to find out the opened-behind. But, fd_lookup gives the recent fd opened on the inode, but the oldest fd(s) (there can be multiple fds opened-behind when the very first opens on an inode are issued in parallel) are the candidates for fds with pending opens on backend. So, this patch explictily tracks the opened-behind fds on an inode and opens them before resuming rename or unlink. similar code changes are also done for setattr and setxattr to make sure pending opens are complete before permission change. This patch also adds a check for an open-in-progress to ob_get_wind_fd. If there is already an open-in-progress, ob_get_wind_fd won't return an anonymous fd as a result. This is done to make sure that rename/unlink/setattr/setxattr don't race with an operation like readv/fstat on an anonymous fd already in progress. Issue 2: ======== once renamed/unlinked, don't open-behind any future opens on the same inode. Issue 3: ======== Don't use anonymous fds by default. Note that rename/unlink can race with a read/fd on anonymous fds and these operations can fail with ESTALE. So, for better consistency in default mode, don't use anonymous fds. If performance is needed with tradeoff of consistency, one can switch on the option "use-anonymous-fd" Change-Id: Iaf130db71ce61ac37269f422e348a45f6ae6e82c Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Updates: bz#1512691

| | | | | | | | | | | | | | | | | | | gluster_shared_storage bricks Problem: In a brick multiplexing environment, Bricks of a normal volume created by user are getting attached to the bricks of a volume "gluster_shared_storage" which is created by enabling the enable-shared-storage option. Mounting gluster_shared_storage has strict authentication checks. when we attach bricks of a normal volume to bricks of gluster_shared_storage, mounting the normal volume created by user will fail due to strict authentication checks. Solution: We should not attach bricks of a normal volume to brick process of gluster_shared_storage volume and vice versa. fixes: bz#1610726 Change-Id: If1b5a2a02675789a2915ba480fb48c145449163d Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* coverity: Fix remaining SECURE_TEMP issues reportedShyamsundarR2018-08-034-10/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Two pending SECURE_TEMP issues still exist in the coverity reports, these are fixed by this patch. In both instances (where functions actually seem to be duplicates of each other) the need was for a FILE * and not an fd. Applied the same pattern in both places as in other parts of the code where mkstemp was used and later a FILE * was created from the resulting fd for use. Coverity report: https://download.gluster.org/pub/gluster/ glusterfs/static-analysis/master/glusterfs-coverity/ 2018-07-30-4d3c62e7/html/ Issues numbered: 382, 383 (named SECURE_TEMP) Further added tmpfile to the blacklist, so that future code changes do not add the same, into symbol-check.sh. Also corrected shellcheck errors in symbol-check.sh as a result of updating the same.

* performance/open-behind: don't use anonymous fds for reads by defaultRaghavendra G2018-08-022-1/+3
| | | | | | | | | | | | | | | | | | | | anonymous fds interfere with working of read-ahead as read-ahead won't be able to store its cache in fd. Also, as seen in bz 1455872, anonymous fds also affect performance of large file sequential reads as the cost of opening fd for each read on brick stack is significant. So, have a proper fd which enables read-ahead to store its cache and brick stack to reuse the fd during reads. With this change test tests/bugs/snapshot/bug-1167580-set-proper-uid-and-gid-during-nfs-access.t fails consistently. The failure can also be seen with open-behind off. bz 1611532 has been filed to track the issue with test. Thanks to Rafi <rkavunga@redhat.com> for assistance provided in debugging test failure.

* performance/md-cache: update cache only from fops issued after previous ↵Raghavendra G2018-08-026-100/+251
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | invalidation Invalidations are triggered mainly by two codepaths - upcall and write-behind unwinding a cached write with zeroed out stat. For the case of upcall, following race can happen: * stat s1 is fetched from brick * invalidation is detected on brick * invalidation is propagated to md-cache and cache is invalidated * s1 updates md-cache with a stale state For the case of write-behind, imagine following sequence of operations, * A stat s1 was issued from application thread t1 when size of file was s1 * stat s1 completes on brick stack, but yet to reach md-cache * A write w1 from application thread t2 extends file to size s2 is cached in write-behind and response is unwound with zeroed out stat * md-cache while handling write-cbk, invalidates cache * md-cache receives response for s1, updates cache with stale stat with size of s1 overwriting invalidation state Fix is to remember when s1 was incident on md-cache and update cache with results of s1 only if the it was incident after invalidation of cache.

* performance/write-behind: better invalidation in readdirpRaghavendra G2018-07-283-24/+36
| | | | | | | | | | | | | | | | | | | | | | | | Current invalidation of stats in wb_readdirp_cbk is prone to races. As the deleted comment explains, <snip> We cannot guarantee integrity of entry->d_stat as there are cached writes. The stat is most likely stale as it doesn't account the cached writes. However, checking for non-empty liability list here is not a fool-proof solution as there can be races like, 1. readdirp is successful on posix 2. sync of cached write is successful on posix 3. write-behind received sync response and removed the request from liability queue 4. readdirp response is processed at write-behind. In the above scenario, stat for the file is sent back in readdirp response but it is stale. </snip> Change-Id: I6ce170985cc6ce3df2382ec038dd5415beefded5 Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Updates: bz#1512691

* performance/readdir-ahead: Invalidate cached dentries if they're modified ↵Krutika Dhananjay2018-07-286-22/+600
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | while in cache PROBLEM: Entries that are readdirp'd ahead can undergo modification in terms of writes, truncates which could modify their iatts. When a readdir is finally wound at offset corresponding to these entries, the iatts that are returned to the application come from readdir-ahead's cache, which are stale by now. This problem gets further aggravated when caching translators/modules cache and continue to serve this stale information. FIX: Whenever a dentry undergoes modification, in the cbk of the modification fop, a "dirty" flag (default 0) is set in its inode ctx. When it's time for readdir-ahead to serve these entries, it will read the inode ctx and check if the entry is "dirty", and if it is, set the entry's attrs to all zeroes, as an indicator to fuse, md-cache etc not to cache these attributes. Also there is one tiny race between the entry creation and a readdirp on its parent dir, which could cause the inode-ctx setting and inode ctx reading to happen on two different inode objects. To prevent this, fuse-bridge is made to drop entries for which dentry->inode is not the same as linked inode, in readdirp cbk.
