* locks: prevent deletion of locked entriesXavi Hernandez2020-06-171-0/+41
| | | | | | | | | | | | | | To keep consistency inside transactions started by locking an entry or an inode, this change delays the removal of entries that are currently locked by one or more clients. Once all locks are released, the removal is processed. It has also been improved the detection of stale inodes in the locking code of EC. Fixes: #990 Change-Id: Ic8ba23d9480f80c7f74e7a310bf8a15922320fd5 Signed-off-by: Xavi Hernandez <xhernandez@redhat.com>
* afr: make heal info locklessRavishankar N2019-12-121-0/+4
| | | | | | | | | | | | | | | | | | | Changes in locks xlator: Added support for per-domain inodelk count requests. Caller needs to set GLUSTERFS_MULTIPLE_DOM_LK_CNT_REQUESTS key in the dict and then set each key with name 'GLUSTERFS_INODELK_DOM_PREFIX:<domain name>'. In the response dict, the xlator will send the per domain count as values for each of these keys. Changes in AFR: Replaced afr_selfheal_locked_inspect() with afr_lockless_inspect(). Logic has been added to make the latter behave same as the former, thus not breaking the current heal info output behaviour. fixes: bz#1774011 Change-Id: Ie9e83c162aa77f44a39c2ba7115de558120ada4d Signed-off-by: Ravishankar N <ravishankar@redhat.com>

* multiple files: another attempt to remove includesYaniv Kaul2019-06-141-1/+0
| | | | | | | | | | | | | | | | | | There are many include statements that are not needed. A previous more ambitious attempt failed because of *BSD plafrom (see https://review.gluster.org/#/c/glusterfs/+/21929/ ) Now trying a more conservative reduction. It does not solve all circular deps that we have, but it does reduce some of them. There is just too much to handle reasonably (dht-common.h includes dht-lock.h which includes dht-common.h ...), but it does reduce the overall number of lines of include we need to look at in the future to understand and fix the mess later one.

This leads to multiple threads in the same client being able to get locks on the inode because lk-owner is same and transport is same. So isolation with locks can't be achieved.

| | | | | | | | | | | | | | | | | design reference: https://review.gluster.org/#/c/glusterfs-specs/+/21925/ This patch adds the lock preempt support. Note: The current model stores lock enforcement information as separate xattr on disk. There is another effort going in parallel to store this in stat(x) of the file. This patch is self sufficient to add fencing support. Based on the availability of the stat(x) support either I will rebase this patch or we can modify the necessary bits post merging this patch.

* Multiple posix related files: several modificationsYaniv Kaul2018-12-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Just looked at posix.c and related code and performed some changes and cleanups. The only important one is #3 below, but surely the others (#2 and #4) need careful review. Changes to other files are as they were related to code paths in posix.c. I'll send a separate patch for other posix related files. Main changes: 1. Proper initializtion for parameters, where it made sense. 2. Logged outside the lock in several places. 3. Moved from CALLOC to MALLOC where it made sense. 4. Aligned structures. 5. moved dictionary functions to use _sizen where possible. (dict_get() -> dict_get_sizen() for example) Compile-tested only!

* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* locks: added inodelk/entrylk contention upcall notificationsXavier Hernandez2018-01-161-2/+10
| | | | | | | | | | | | | | The locks xlator now is able to send a contention notification to the current owner of the lock. This is only a notification that can be used to improve performance of some client side operations that might benefit from extended duration of lock ownership. Nothing is done if the lock owner decides to ignore the message and to not release the lock. For forced release of acquired resources, leases must be used.

* features/locks: Add lock revocation functionality to posix locks translatorRichard Wareing2016-07-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: - Motivation: Prevents cluster instability by mis-behaving clients causing bricks to OOM due to inode/entry lock pile-ups. - Adds option to strip clients of entry/inode locks after N seconds - Adds option to clear ALL locks should the revocation threshold get hit - Adds option to clear all or granted locks should the max-blocked threshold get hit (can be used in combination w/ revocation-clear-all). - Options are: features.locks-revocation-secs <integer; 0 to disable> features.locks-revocation-clear-all [on/off] features.locks-revocation-max-blocked <integer> - Adds monkey-locking option to ignore 1% of unlock requests (dev only) features.locks-monkey-unlocking [on/off] - Adds logging to indicate revocation event & reason Test Plan: First you will need TWO fuse mounts for this repro. Call them /mnt/patchy1 & /mnt/patchy2. 1. Enable monkey unlocking on the volume: gluster vol set patchy features.locks-monkey-unlocking on 2. From the "patchy1", use DD or some other utility to begin writing to a file, eventually the dd will hang due to the dropped unlocked requests. This now simulates the broken client. Run: for i in {1..1000};do dd if=/dev/zero of=/mnt/patchy1/testfile bs=1k count=10;done' ...this will eventually hang as the unlock request has been lost. 3. Goto another window and setup the mount "patchy2" @ /mnt/patchy2, and observe that 'echo "hello" >> /mnt/patchy2/testfile" will hang due to the inability of the client to take out the required lock. 4. Next, re-start the test this time enabling lock revocation; use a timeout of 2-5 seconds for testing: 'gluster vol set patchy features.locks-revocation-secs <2-5>' 5. Wait 2-5 seconds before executing step 3 above this time. Observe that this time the access to the file will succeed, and the writes on patchy1 will unblock until they hit another failed unlock request due to "monkey-unlocking".

* posix/lock: implement meta-lock/unlock functionalitySusant Palai2016-06-031-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | problem : The lock state needs to be protected when rebalance is reading the lock state on the source. Otherwise there will be locks left unmigrated. Hence, to synchronize incoming lock requests with lock-migration, meta lock is needed. Any new lock request will be queued if there is an active meta-lock and with sucessful lock migration, will be unwound with EREMOTE, so that dht module can wind the request to the correct destination. On a successful lock migration, "pl_inode->migrated" flag is enabled. Hence, any further request would be unwound with EREMOTE and will be redirected to new destination.

* cluster/ec: Rebalance hangs during renameAshish Pandey2016-03-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: During the rename of a particular file (ec is holding blocking inodelk on the parent directory), if the rename of another file under the same directory comes. EC does not release the lock and goes ahead and renames the "new" file with the "already held lock". That causes rebalance process to be blocked on a lock which has been acquired by rename. Solution: While rename fop comes, ec takes blocking inodelk on old and new parent of the file. Before releasing, every lock held by ec, it waits for some "time" to see if that lock can be reused by the next fop. If within this "time" some other request comes, it releases this lock based on condition "lock count > 1" To get this "lock count" for rename fop, we have implemented "pl_rename" in feature/lock. Also, on ec side, changed the condition to release the lock based on the type of fop and old and new parent directories.

| | | | | | | | | | | | This patch solves the lock bailout problem seen recently when autoconf tools were run. This is a workaround, where 'flock' locks are removed in pl_release, if an explicit UNLCK call does not come. The complete fix would be to allow 'fcntl' and 'flock' locks to operate in different domains. Signed-off-by: Pavan Vilas Sondur <pavan@gluster.com> Signed-off-by: Anand V.
