* dht/md-cache: Filter invalidate if the file is made a linkto filePoornima G2017-01-041-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/15789 Upcall as a part of setattr, sends an invalidation and the invalidation carries the resulting stat value. When a file is converted to linkto files, even then an invalidation is set and as a result the mountpoint shows the sticky bit in the stat of the file. eg: ---------T. 945 root root 0 Nov 8 10:14 hardlink.999 Fix: When dht recieves a notification of sticky bit change, it updates the flag, to indicate md-cache to send the subsequent lookup. >Reviewed-on: http://review.gluster.org/15789 >Smoke: Gluster Build System <jenkins@build.gluster.org> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >Reviewed-by: Niels de Vos <ndevos@redhat.com> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: Susant Palai <spalai@redhat.com> >Reviewed-by: Rajesh Joseph <rjoseph@redhat.com> >(cherry picked from commit 4536f7bdf16f8286d67598eda9a46c029f0c0bf4) Change-Id: Ic2fd7a5b196db0754f9b97072e644e6bf69da606 BUG: 1401376 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/16022 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>
* cluster/dht: Fix memory corruption while accessing regex stored inRaghavendra G2017-01-033-45/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | private If reconfigure is executed parallely (or concurrently with dht_init), there are races that can corrupt memory. One such race is modification of regexes stored in conf (conf->rsync_regex_valid and conf->extra_regex_valid) through dht_init_regex. With change [1], reconfigure codepath can get executed parallely (with itself or with dht_init) and this fix is needed. Also, a reconfigure can race with any thread doing dht_layout_search, resulting in dht_layout_search accessing regex freed up by reconfigure (like in bz 1399134).

* afr,dht,ec: Replace GF_EVENT_CHILD_MODIFIED with event SOME_DESCENDENT_DOWN/UPPoornima G2016-12-131-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/#/c/15764/ Currently these are few events related to child_up/down: GF_EVENT_CHILD_UP : Issued when any of the protocol client connects. GF_EVENT_CHILD_MODIFIED : Issued by afr/dht/ec GF_EVENT_CHILD_DOWN : Issued when any of the protocol client disconnects. These events get modified at the dht/afr/ec layers. Here is a brief on the same. DHT: - All the subvolumes reported once, and atleast one child came up, then GF_EVENT_CHILD_UP is issued - connect GF_EVENT_CHILD_UP is issued - disconnect GF_EVENT_CHILD_MODIFIED is issued - All the subvolumes disconnected, GF_EVENT_CHILD_DOWN is issued AFR: - First subvolume came up, then GF_EVENT_CHILD_UP is issued - Subsequent subvolumes coming up, results in GF_EVENT_CHILD_MODIFIED - Any of the subvolumes go down, then GF_EVENT_SOME_CHILD_DOWN is issued - Last up subvolume goes down, then GF_EVENT_CHILD_DOWN is issued Until the patch [1] introduced GF_EVENT_SOME_CHILD_UP, GF_EVENT_CHILD_MODIFIED was issued by afr/dht when any of the subvolumes go up or down. Now with md-cache changes, there is a necessity to differentiate between child up and down. Hence, introducing GF_EVENT_SOME_DESCENDENT_DOWN/UP and getting rid of GF_EVENT_CHILD_MODIFIED.

* dht/rename : Incase of failure remove linkto file properlyJiffin Tony Thottan2016-12-062-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generally linkto file is created using root user. Consider following case, a user is trying to rename a file which he is not permitted. So the rename fails with EACESS and when rename tries to cleanup the linkto file, it fails. The above issue happens when rename/00.t test executed on nfs-ganesha clients : Steps executed in script * create a file "abc" using root * rename the file "abc" to "xyz" using a non root user, it fails with EACESS * delete "abc" * create directory "abc" using root * again try ot rename "abc" to "xyz" using non root user, test hungs here which slowly leds to OOM kill of ganesha process RCA put forwarded by Du for OOM kill of ganesha Note that when we hit this bug, we've a scenario of a dentry being present as: * a linkto file on one subvol * a directory on rest of subvols When a lookup happens on the dentry in such a scenario, the control flow goes into an infinite loop of: dht_lookup_everywhere dht_lookup_everywhere_cbk dht_lookup_unlink_cbk dht_lookup_everywhere_done dht_lookup_directory (as local->dir_count > 0) dht_lookup_dir_cbk (sets to local->need_selfheal = 1 as the entry is a linkto file on one of the subvol) dht_lookup_everywhere (as need_selfheal = 1). This infinite loop can cause increased consumption of memory due to: 1) dht_lookup_directory assigns a new layout to local->layout unconditionally 2) Most of the functions in this loop do a stack_wind of various fops. This results in growing of call stack (note that call-stack is destroyed only after lookup response is received by fuse - which never happens in this case) Thanks Du for root causing the oom kill and Sushant for suggesting the fix Upstream reference : >Change-Id: I1e16bc14aa685542afbd21188426ecb61fd2689d >BUG: 1397052 >Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com> >Reviewed-on: http://review.gluster.org/15894 >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> >Smoke: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: Raghavendra G <rgowdapp@redhat.com> >(cherry picked from commit 57d59f4be205ae0c7888758366dc0049bdcfe449) Change-Id: I1e16bc14aa685542afbd21188426ecb61fd2689d BUG: 1401023 Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com> Reviewed-on: http://review.gluster.org/16014 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com>

* dht, md-cache, upcall: Add invalidation of IATT when the layout changesPoornima G2016-08-301-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: dht_layout is built as a part of lookup only. The layout can be modified by rebalance process. Since every IO fop is preceded by a lookup, there are very less issues of stale layout. But with enhancements of aggressive caching of stats in md-cache, the lookup will reduce and expose the stale layout issue often. Solution: Since stale layout is already an issue on dht, there is already a plan to fix this at the dht layer, but this fix is not currently planned for any release. Until this fix comes out, we can have a workaround where, the upcall will send a notification to md-cache when a layout xattr is changed. As a part of layout change notification the existing cache is invalidated and the next lookup will fetch the latest layout. This is not a foolproof solution as the window between the layout change and the next lookup(after invalidation of stat), where there will be stale layout. But until the final fix comes in, this reduces the stale layout window.

* cluster/tier: fix statfs for dht/tiered volumesDan Lambright2016-07-276-22/+265
| | | | | | | | | | | | | | | | | | | | | | | | | Return the correct size of the tiered volume in statfs. It should be the size of the cold tier, not the sum of the hot and cold tier, because the hot tier is a cache and not an extension of the volume's capacity. The number of free blocks, etc is the cold tier's capacity subtracted by the sum of utilization on the hot and cold tiers. Note if both tiers are part of the same file system this must be accounted for as well. The patch also fixes a pre-existing bug in the DHT/tier translators. If statfs was taken on a file, the code only calculated free space on the cached subvolume, not all subvolumes in the replica group. With the fix, this is corrected, except in the case where quota is used with the deem-statfs option set to "on".

These will be addressed in subsequent patches. This patch addresses only mkdir codepath. This change breaks stripe tests, as on some striped subvols dht layout xattrs are not set for some reason. This results in failure of mkdir. Since striped volumes are always created with dht, some tests associated with stripe also fail. So, I am making following tests changes (since stripe is out of maintainance): * modify ./tests/basic/rpc-coverage.t to not to use striped volumes * mark all (2) tests in tests/bugs/stripe/ as bad tests Change-Id: Idd1ae879f24a48303dc743c1bb4d91f89a629e25 BUG: 1323040 Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Reviewed-on: http://review.gluster.org/13885 Smoke: Gluster Build System <jenkins@build.gluster.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: N Balachandran <nbalacha@redhat.com>
* quota: setting 'read-only' option in xdata to instruct DHT to not healSakshi Bansal2016-04-191-2/+10
| | | | | | | | | | | | | | | | | | | | | | When quota is enabled the quota enforcer tries to get the size of the source directory by sending nameless lookup to quotad. But if the rename is successful even on one subvol or the source layout has anomalies then this nameless lookup in quotad tries to heal the directory which requires a lock on as many subvols as it can. But src is already locked as part of rename. For rename to proceed in brick it needs to complete a cluster-wide lookup. But cluster-wide lookup in quotad is blocked on locks held by rename, hence a deadlock. To avoid this quota sends an option in xdata which instructs DHT not to heal.

* dht: add "nuke" functionality for efficient server-side deletionJeff Darcy2016-04-071-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This turns a special xattr into an rmdir with flags set. When that hits the posix translator on the server side, that causes the file/directory to be moved into the special "landfill" directory. From there, the posix janitor thread will take care of deleting it entirely on the server side - traversing it recursively if necessary. A couple of secondary issues were fixed to make this effective. * FUSE now ensures that setxattr values are NUL terminated. * The janitor thread now gets woken up immediately when something is placed in 'landfill' instead of only when file descriptors need to be closed. * The default landfill-emptying interval was reduced to 10s. To use the feature, issue a setxattr something like this: setfattr -n glusterfs.dht.nuke -v "" /mnt/glusterfs/vol/some_dir The value doesn't actually matter; the mere receipt of a request with this key is sufficient. Some day it might be useful to allow setting a required value as a sort of password, so that only those who know it can access the underlying special functionality.

* dht: lock on subvols to prevent rename and lookup selfheal raceSakshi2016-04-061-43/+158
| | | | | | | | | | | | | | | | | | | | | | This patch addresses two races while renaming directories: 1) While renaming src to dst, if a lookup selfheal is triggered it can recreate src on those subvols where rename was successful. This leads to multiple directories (src and dst) having same gfid. To avoid this we must take locks on all subvols with src. 2) While renaming if the dst exists and a lookup selfheal is triggered it will find anomalies in the dst layout and try to heal the stale layout. To avoid this we must take lock on any one subvol with dst.
