* features/worm: Adding implementation for ftruncatekarthik-us2017-04-131-2/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Since the ftruncate fop was not handled in the worm feature, when truncate and write was happening on a worm-retained/worm file, it was giving the EROFS error but truncating the file, which is not correct. > Change-Id: I1a7e904655210d78bce9e01652ac56f3783b5aed > BUG: 1438810 > Signed-off-by: karthik-us <ksubrahm@redhat.com> > Reviewed-on: https://review.gluster.org/16995 > 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: Ravishankar N <ravishankar@redhat.com> > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Amar Tumballi <amarts@redhat.com> > Reviewed-by: Raghavendra Talur <rtalur@redhat.com> (cherry picked from commit c5a4a77848024d2adf8cd4f35d550ba90c174fc7) Change-Id: I815049d37d95597021e11b1e3d25d56bb83623c4 BUG: 1437763 Signed-off-by: karthik-us <ksubrahm@redhat.com> Reviewed-on: https://review.gluster.org/16999 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: Ravishankar N <ravishankar@redhat.com> Reviewed-by: jiffin tony Thottan <jthottan@redhat.com> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
* features/read-only: reten_mode is invalid to be free by mem_put()Ryan Ding2016-10-181-11/+0
| | | | | | | | | | | | | | | | priv->reten_mode is initialised by option 'retention-mode'. and it reference the memory in this->options. so fini() use mem_put to free priv->reten_mode will cause a problem. there is no need to call mem_put(), so just remove it will be fine.

* features/worm: fixed issue with write FOP for normal fileskarthik-us2016-06-131-1/+4
| | | | | | | | | | | | | | | | | The write FOPs on normal files were being blocked after the recent change. It should fail only for the WORM and WORM-Retained files, and should pass for a normal file. Using auto-commit period to check for dormant files instead of retention period.

* WORM/Retention Translator: Implementation of file level WORMkarthik-us2016-05-011-29/+454
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To activate the file level worm feature, the features.read-only and features.worm options should be switched "off" on the volume and the features.worm-file-level should be switched "on". Both read-only and worm or worm-file-level cannot be switched "on" together. The files which are created when the worm-file-level option is set on the volume will have their own retention profile. If both worm and worm-file-level are "on" at that time the worm which is the volume level worm will have priority over file level worm. If worm-file level is switched "off" after some time and the read-only option is switched "on" then read-only will have priority. The current implementation allows the users to manually transmit a file to a WORM-Retained state by removing all the write bits of the file using the chmod command. The file will have a retention profile which contains the state of the file, mode of retention, and the default retention time. The file will be made WORM-Retained for a default of 120 seconds during which it will be immutable and undeletable and it sets the atime of the file to the time till which it is retained. After that period if any fop request comes for that file, will make the transition from WORM-Retained state to WORM state, where the file will be immutable but deletable and, it will reset the atime to the actual atime of the file. If a WORM file needs to be made undeletable again, it can be done by using the chmod command with all the write bits removed. There are two modes of retention: 1. Relax: where the retention time of a WORM-Retained file can be increased or decreased. 2. Enterprise: where the retention time of a WORM-Retained file can be increased but not be decreased. Whenever a utime change(touch -a, -t, ...)request comes for a file it checks the mode of retention before setting the utimes. This is done only if the file is WORM-Retained but for a WORM file it will change the utimes. Lazy auto commit: Whenever a file gets created it will store the creation time of the file or if a file already exists then any of the next unlink, link, truncate or rename fops will set the current time as the start time in an xattr. The next rename/unlink/truncate/link call will check for the auto commit period and if is is expired, then it will automatically do the state transition. If it is a normal file then it gets converted to WORM-Retained state. If it is a WORM-Retained file and its retention period is expired, then it gets converted to WORM state. Added the volume set options for the WORM translator. It allows the users to change the default values of auto-commit-period, default-retention-period, retention-mode. To make use of the file-level WORM first we have to set the 'worm-file' option to 'on'. The files which are created when the worm-file option is set on the volume will get WORM-Retained. Other files will work as usual and will not be WORMed. The auto-commit-period, retention-mode, and the default-retention-period values for the file will be set to the values which are set on the volume when the file is created. Added the tests to check the basic functionalities of the WORM/Retention feature.

* read-only: read-only/worm translator should be in brick graph by defaultAtin Mukherjee2015-03-241-4/+64
| | | | | | | | | | | | | | | | | | | | | Problem: read-only/worm translator is not loaded by default in brick graph because of which when read-only option is set through volume set volume still remains writable untill the bricks are restarted as the translator does not have an inmemory flag to decide whether the read-only/worm option is turned or not. Solution: read-only/worm should be loaded by default in brick graph and the read-only/worm option can be toggled through volume set command. read-only/worm translator now' has an in-memory flag to decide whether the volume is read-only or not and based on that either reject the fop or proceed.
