* dentry fop serializer: added new server side xlator for dentry fop serializationSakshi Bansal2018-01-306-4/+1492
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problems addressed by this xlator : [1]. To prevent race between parallel mkdir,mkdir and lookup etc. Fops like mkdir/create, lookup, rename, unlink, link that happen on a particular dentry must be serialized to ensure atomicity. Another possible case can be a fresh lookup to find existance of a path whose gfid is not set yet. Further, storage/posix employs a ctime based heuristic 'is_fresh_file' (interval time is less than 1 second of current time) to check fresh-ness of file. With serialization of these two fops (lookup & mkdir), we eliminate the race altogether. [2]. Staleness of dentries This causes exponential increase in traversal time for any inode in the subtree of the directory pointed by stale dentry. Cause : Stale dentry is created because of following two operations: a. dentry creation due to inode_link, done during operations like lookup, mkdir, create, mknod, symlink, create and b. dentry unlinking due to various operations like rmdir, rename, unlink. The reason is __inode_link uses __is_dentry_cyclic, which explores all possible path to avoid cyclic link formation during inode linkage. __is_dentry_cyclic explores stale-dentry(ies) and its all ancestors which is increases traversing time exponentially. Implementation : To acheive this all fops on dentry must take entry locks before they proceed, once they have acquired locks, they perform the fop and then release the lock. Some documentation from email conversation: [1] http://www.gluster.org/pipermail/gluster-devel/2015-December/047314.html [2] http://www.gluster.org/pipermail/gluster-devel/2015-August/046428.html With this patch, the feature is optional, enable it by running: `gluster volume set $volname features.sdfs enable` Also the feature is tested for a month without issues in the experiemental branch for all the regression.

* libgfapi: Add new api for supporting mandatory-locksAnoop C S2018-01-221-1/+1
| | | | | | | | | | | | | | | | The current API for byte-range locks [glfs_posix_lock()] doesn't allow applications to specify whether it is advisory or mandatory type locks. This particular change is to introduce an extended byte-range lock API with an additional argument for including the byte-range lock mode to be one among advisory(default) or mandatory. Patch also includes a gfapi test case which make use of this new api to acquire mandatory locks.

* upcall: Allow md-cache to specify invalidations on xattr with wildcardPoornima G2018-01-191-4/+21
| | | | | | | | | | | | | Currently, md-cache sends a list of xattrs, it is inttrested in recieving invalidations for.

* locks: added inodelk/entrylk contention upcall notificationsXavier Hernandez2018-01-167-159/+540
| | | | | | | | | | | | | | 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.

* build: Link libgfrpc within rpc-transport shared librariesAnoop C S2018-01-111-2/+4
| | | | | | | | | | | | | | | | | Now with https://review.gluster.org/#/c/19056/ merged, we perform dlopen() with RTLD_LOCAL so that every shared library is expected to be explicitly linked against other required libraries. "undefined symbol ..." was seen while trying to access GlusterFS volumes via NFS-Ganesha/Samba using libgfapi resulting in an unusable state. This is a follow-up patch to https://review.gluster.org/#/c/17659/ to make sure that we link libgfrpc too while making socket and rdma rpc-transport shared libraries.

| | | | | | | | | | | | | | quiesce is useful in a gfproxy setup where if gfproxy machine goes down the fop would be replayed. Hence only added the fops which is supported by fuse layer to start with. With this patch, no behavior change is added (ie, volfile change etc). Just making sure to have the translator up-to-date so that if required we can consume it.

* Use RTLD_LOCAL for symbol resolutionPrashanth Pai2017-12-271-0/+19
| | | | | | | | | | | | | RTLD_LOCAL is the default value for symbol visibility flag of dlopen() in Linux and NetBSD. Using it avoids conflicts during symbol resolution. This also allows us to detect xlators that have not been explicitly linked with libraries that they use. This used to go unnoticed when RTLD_GLOBAL was being used.

* feature/bitrot: remove internal xattrs from lookup cbkRavishankar N2017-12-192-7/+21
| | | | | | | | | | | | | | | | | | | | | Problem: afr requests all xattrs in lookup via the list-xattr key. If bitrot is enabled and later disabled, or if the bitrot xattrs were present due to an older version of bitrot which used to create the xattrs without enabling the feature, the xattrs (trusted.bit-rot.version in particular) was not getting filtered and ended up reaching the client stack. AFR, on noticing different values of the xattr across bricks of the replica, started triggering spurious metadata heals. Fix: Filter all internal xattrs in bitrot xlator before unwinding lookup, (f)getxattr. Thanks to Kotresh for the help in RCA'ing.

* glusterfs: Use gcc builtin ATOMIC operator to increase/decreate refcount.Mohit Agrawal2017-12-122-15/+9

Add all the configuration options to a volume to activate file-level-worm 2. Option features.worm-files-deletable is set to 1 by default. 3. Create a new file and wait for the retention time to expire. 4. After retention time expires, do an truncate, rename, unlink, link or write to send the file in Worm state. 5. After that do `rm -f filename`. 6. The file is successfully removed. 7. Repeat from step 2 by setting features.worm-files-deletable 0. This time deletion should not be successful.
