* mdcache: Fix asan reported potential heap buffer overflowShyamsundarR2018-09-281-0/+1
| | | | | | | | | | | | | | The char pointer mdc_xattr_str in function mdc_xattr_list_populate is malloc'd and doing a strcat into a malloc'd region can overflow content allocated based on prior contents of the memory region. Added a NULL terimation to the malloc'd region to prevent the overflow, and treat it as an empty string.

* python3: assume python3 unless building _packages_ on sys without py3Kaleb S. KEITHLEY2018-09-2713-24/+7
| | | | | | | | | | | | | | | The jenkins release-new job runs on a CentOS 7 box, which does not have python3. As a result it runs (autogen.sh and) configure before producing the dist tar file, converting all the python3 shebangs to python2 shebangs in the dist tar file. Then when that tar file is "carried" to, e.g. Fedora koji build system to build packages, the shebangs are incorrect, despite having originally been correct in the git repo.

* rpc: failed requests immediately if rpc connection is downKinglong Mee2018-09-271-1/+4
| | | | | | | | | | | | In the case glfs_fini is ongoing, some cache xlators like readdir-ahead, continues to submit requests. Current rpc submit code ignores connection status and queues these internally generated requests. These requests then got cleaned up after inode table has been destroyed, causing crash.

* glusterd: make sure that brickinfo->uuid is not nullSanju Rakonde2018-09-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: After an upgrade from the version where shared-brick-count option is not present to a version which introduced this option causes issue at the mount point i.e, size of the volume at mount point will be reduced by shared-brick-count value times. Cause: shared-brick-count is equal to the number of bricks that are sharing the file system. gd_set_shared_brick_count() calculates the shared-brick-count value based on uuid of the node and fsid of the brick. https://review.gluster.org/#/c/glusterfs/+/19484 handles setting of fsid properly during an upgrade path. This patch assumed that when the code path is reached, brickinfo->uuid is non-null. But brickinfo->uuid is null for all the bricks, as the uuid is null https://review.gluster.org/#/c/glusterfs/+/19484 couldn't reached the code path to set the fsid for bricks. So, we had fsid as 0 for all bricks, which resulted in gd_set_shared_brick_count() to calculate shared-brick-count in a wrong way. i.e, the logic written in gd_set_shared_brick_count() didn't work as expected since fsid is 0. Solution: Before control reaches the code path written by https://review.gluster.org/#/c/glusterfs/+/19484, adding a check for whether brickinfo->uuid is null and if brickinfo->uuid is having null value, calling glusterd_resolve_brick will set the brickinfo->uuid to a proper value. When we have proper uuid, fsid for the bricks will be set properly and shared-brick-count value will be caluculated correctly. Please take a look at the bug https://bugzilla.redhat.com/show_bug.cgi?id=1632889 for complete RCA Steps followed to test the fix: 1. Created a 2 node cluster, the cluster is running with binary which doesn't have shared-brick-count option 2. Created a 2x(2+1) volume and started it 3. Mouted the volume, checked size of volume using df 4. Upgrade to a version where shared-brick-count is introduced (upgraded the nodes one by one i.e, stop the glusterd, upgrade the node and start the glusterd). 5. after upgrading both the nodes, bumped up the cluster.op-version 6. At mount point, df shows the correct size for volume. fixes: bz#1632889 Change-Id: Ib9f078aafb15e899a01086eae113270657ea916b Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* glusterd: don't wait for blockers flag for stop volumeAtin Mukherjee2018-09-221-1/+0
| | | | | | | | | | | | | | | With commit 4f6ae8 even though the overall transaction time for gluster volume stop can be reduced, but based on testing it can't be guaranteed that the transaction can finish in 3 minutes before the unlock timer gets kicked in. The ground problem to this is the command serialization which atomic field 'blockers' does for volume stop operation. This patch removes that dependency for volume stop not to wait for blockers.

* cluster/afr: Make data eager-lock decision based on number of locksPranith Kumar K2018-09-213-6/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For both Virt and block workloads the file is opened multiple times leading to dynamically setting eager-lock to off for the workload. Instead of depending on the number-of-open-fds, if we change the logic to depend on number of inodelks, then it will give better performance than the earlier logic. When there is an eager-lock and number of inodelks is more than 1 we know that there is a conflicting lock, so depend on that information to decide whether to keep the current transaction go through delayed-post-op or not. Locks xlator doesn't have implementation to query number of locks in fxattrop in releases older than 3.10 so to keep things backward compatible in 3.12, data transactions will use new logic where as fxattrop transactions will use old logic. I am planning to send one more patch which makes metadata domain locks also depend on inodelk-count Profile info for a dd of 500MB to a file with another fd opened on the file using exec 250>filename Without this patch: 0.14 67.41 us 16.72 us 3870.82 us 892 FINODELK 0.59 279.87 us 95.71 us 2085.89 us 898 FXATTROP 3.46 366.43 us 81.75 us 6952.79 us 4000 WRITE 95.79 148733.99 us 50568.12 us 919127.86 us 273 FSYNC With this patch: 0.00 51.01 us 38.07 us 80.16 us 4 FINODELK 0.00 235.43 us 235.43 us 235.43 us 1 TRUNCATE 0.00 125.07 us 56.80 us 193.33 us 2 GETXATTR 0.00 135.86 us 62.13 us 209.59 us 2 INODELK 0.00 197.88 us 155.39 us 253.90 us 4 FXATTROP 0.00 450.59 us 394.28 us 506.89 us 2 XATTROP 0.00 56.96 us 19.06 us 406.59 us 23 FLUSH 37.81 273648.93 us 48.43 us 6017657.05 us 44 LOOKUP 62.18 4951.86 us 93.80 us 1143154.75 us 3999 WRITE postgresql benchmark performance changed from ~1130 TPS to ~2300TPS randio fio job inside Ovirt based VM went from ~600IOPs to ~2000IOPS fixes bz#1630368 Change-Id: If7f7388d2f08cf7f17ca517a4ea222560661dc36 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

* cluster/afr: Use 2 domain locking in SHD for thin-arbiterkarthik-us2018-09-205-91/+392
| | | | | | | | | | | | | | | | | | | | With this change when SHD starts the index crawl it requests all the clients to release the AFR_TA_DOM_NOTIFY lock so that clients will know the in memory state is no more valid and any new operations needs to query the thin-arbiter if required. When SHD completes healing all the files without any failure, it will again take the AFR_TA_DOM_NOTIFY lock and gets the xattrs on TA to see whether there are any new failures happened by that time. If there are new failures marked on TA, SHD will start the crawl immediately to heal those failures as well. If there are no new failures, then SHD will take the AFR_TA_DOM_MODIFY lock and unsets the xattrs on TA, so that both the data bricks will be considered as good there after.

* glusterd: Use GF_ATOMIC to update 'blockers' counter at glusterd_confMohit Agrawal2018-09-204-12/+11
| | | | | | | | | | | | | | | Problem: Currently in glusterd code uses sync_lock/sync_unlock to update blockers counter which could add delays to the overall transaction phase escpecially when there's a batch of volume stop operations processed by glusterd in brick multiplexing mode. Solution: Use GF_ATOMIC to update blocker counter to ensure unnecessary context switching can be avoided.

* cluster/afr: Batch writes in same lock even when multiple fds are openPranith Kumar K2018-09-191-9/+2
| | | | | | | | | | | | | | | | | | | | | | Problem: When eager-lock is disabled because of multiple-fds opened and app writes come on conflicting regions, the number of locks grows very fast leading to all the CPU being spent just in locking and unlocking by traversing huge queues in locks xlator for granting locks. Fix: Reduce the number of locks in transit by bundling the writes in the same lock and disable delayed piggy-pack when we learn that multiple fds are open on the file. This will reduce the size of queues in the locks xlator. This also reduces the number of network calls like inodelk/fxattrop. Please note that this problem can still happen if eager-lock is disabled as the writes will not be bundled in the same lock. fixes bz#1625961 Change-Id: I8fd1cf229aed54ce5abd4e6226351a039924dd91 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
* dht: utilize the framework to pass-through xlator tasksAmar Tumballi2018-09-1910-31/+234
| | | | | | | | | | | | | | | | | | | | | Also fixes the issue caused due to not converting back the fn function to after getting its address. We wanted the value of the field, not the address of the pt_fop field. With this patch, DHT will always be started in pass-through mode if the number of subvols is just 1. Fixes some tests to make sure DHT is in full config (ie, subvols > 1). - increased timeout of brick-mux test as it was bordering on 300 seconds. - Also change the volume type to supported 'replica 3' from 'replica 2'. - also no DHT tests should assume presence of DHT when there is just 1 brick in volume Credits: Nithya B <nbalacha@redhat.com> fixes: #405 Change-Id: I8e55239ce58d6ac6ae1901e2e384be1ecbd33d6e Signed-off-by: Amar Tumballi <amarts@redhat.com>
