* glusterd: Restarting glusterd should not reset bitrot tunable value to defaultGaurav Kumar Garg2015-04-132-3/+26
| | | | | | | | | | | | | | | | | | | Previously when user restart glusterd then bitrot tunable value for option "scrub-throttle", "scrub-frequency", "scrub" cleared. glusterd was not storing these bitrot tunable value properly. With this fix it will store scrub-throttle, scrub-frequency, scrub, bitrot tunable value in /var/lib/glusterd/vols/<volname>/info file and it will resume these value when glusterd restart.

* bitrot/glusterd: Scrubber should not crawl bricks if bitrot is not enableGaurav Kumar Garg2015-04-131-12/+11
| | | | | | | | | | | | | | | | | | If user create multiple volume and user enable bitrot only for few volume then scrubber should not crawl bricks of volume on which bitrot is not enable. Fix is while volfile generation check whether bitrot is enable on that particular volume or not. If bitrot is enable then only it add bricks of that volume in scrubber volfile.

* glusterd: Replace transaction peers listsKaushal M2015-04-1312-318/+404
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Transaction peer lists were used in GlusterD to peers belonging to a transaction. This was needed to prevent newly added peers performing partial transactions, which could be incorrect. This was accomplished by creating a seperate transaction peers list at the beginning of every transaction. A transaction peers list referenced the peerinfo data structures of the peers which were present at the beginning of the transaction. RCU protection of peerinfos referenced by the transaction peers list is a hard problem and difficult to do correctly. To have proper RCU protection of peerinfos, the transaction peers lists have been replaced by an alternative method to identify peers that belong to a transaction. The alternative method is to the global peers list along with generation numbers to identify peers that should belong to a transaction. This change introduces a global peer list generation number, and a generation number for each peerinfo object. Whenever a peerinfo object is created, the global generation number is bumped, and the peerinfos generation number is set to the bumped global generation. With the above changes, the algorithm to identify peers belonging to a transaction with RCU protection is as follows, - At the beginning of a transaction, the current global generation number is saved - To identify if a peers belonging to the transaction, - Start a RCU read critical section - For each peer in the global peers list, - If the peers generation number is not greater than the saved generation number, continue with the action on the peer - End the RCU read critical section The above algorithm guarantees that, - The peer list is not modified when a transaction is iterating through it - The transaction actions are only done on peers that were present when the transaction started But, as a transaction could iterate over the peers list multiple times, the algorithm cannot guarantee that same set of peers will be selected every time. A peer could get deleted between two iterations of the list within a transaction. This problem existed with transaction peers list as well, but unlike before now it will not lead to invalid memory access and potential crashes. This problem will be addressed seprately. This change was developed on the git branch at [1].

* crypt xlator: Fix memory coruption after freeEmmanuel Dreyfus2015-04-112-1/+2
| | | | | | | | | | | | | | | | | | | | | | crypt xlator allocated local memory through mem_get0(), but code called through STACK_DESTROY()/FRAME_DESTROY() does not expect memory to be allocated that way: it will use GF_FREE() even for data allocated by mem_get0(), which should be given the mem_put() treatment. As a result, allocating using mem_get0(), while relying on FRAME_DESTROY() cleanup led to memory corruption. Using GF_CALLOC() instead of mem_get0() sets memory allocation on par with cleanup code, and crypt.t can pass on NetBSD. The initial patch was crafted by Raghavendra Talur.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fix will solve the heating of the files during the promotion or demotion. Promotion: ~~~~~~~~~ When a file gets promoted it get the current time stamp during creation only, but following writes or reads during the migration wont heat the file. Demotion: ~~~~~~~~ When a file gets demoted it get the wind/unwind time stamp is set to zero. The following writes or reads during the migration wont heat the file. What is remaining ? ~~~~~~~~~~~~~~~~~ Bug 1209129 ( https://bugzilla.redhat.com/show_bug.cgi?id=1209129 ) Inspite of this fix there is still a issue remaining, i.e the heat of the file is not keep intact during a internal rebalance activity i.e a rebalance within a tier.

* bitrot/scrub: Scrubber fixesVenky Shankar2015-04-088-88/+314
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a handful of problem with scrubber which are detailed below. Scrubber used to skip objects for verification due to missing fd iterface to fetch versioning extended attributes. Similar to the inode interface, an fd based interface in POSIX is now introduced. Moreover, this patch also fixes potential false reporting by scrubber due to: An object gets dirtied and signed when scrubber is busy calculatingobject checksum. This is fixed by caching the signed version when an object is first inspected for stalenes, i.e., during pre-compute stage. This version is used to verify checksum in the post-compute stage when the signatures are compared for possible corruption. Side effect of _not_ sending signature length during signing resulted in "truncated" signature to be set for an object. Now, at the time of signing, the signature length is sent and is used in place of invoking strlen() to get signature length (which could have possible 00s). The signature length itself is not persisted in the signature xattr, but is calculated on-the-fly by substracting the xattr length by the "structure" header size. Some of the log entries are made more meaningful (as and aid for debugging).

* tests/bitrot-stub: Object versioning test(s)Venky Shankar2015-04-082-16/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces basic object versioning test(s) which is required for bitrot detection to work correctly. Basic test(s) such as opening a file in read-only mode, single open, multiple open()s are covered on FUSE mount _only_ as stub does not support anonymous fds yet. For this reason, the test case disables open-behind. Actual verification is implemented as a C source which makes use of the same on-disk data structures as used by the stub code. The data structures are moved to separate header file which is included by the test script. Such modularization helps in future enhancements to keep the version "data type" opaque and provide handful of APIs version checking (equal/greater/etc..). [ This is just a start and should grow over time as stub is enhanced and codebase matures. ] Change-Id: Ibee20e65a15b56bbdd59fd2703f9305b115aec7a BUG: 1201724 Signed-off-by: Venky Shankar <vshankar@redhat.com> Reviewed-on: http://review.gluster.org/10140 Reviewed-by: Raghavendra Bhat <raghavendra@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

While assigning initial version to an object, both extended attributes (namely, ongoing version and the default signing version) were persisted. This is optimized to just persist the ongoing version along with safe handling of xattr request(s) in it's absence. This is better than the earlier approach as the two xattr sets were not atomic anyway (allowing a request to sneak in between between two set operations). This also allows to perform sanity checks on objects during lookup()/getxattr(): objects with missing ongoing version but presence of signature are possible candidates of tampering (and catching implementation bugs). There were couple of instances in the code where versioning xattrs were incorrectly removed before in-memory versions were initialized, which have been fixed with this patch. A memory leak in the IPC code path is also fixed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Expected behavior of get_real_filename feature. A getxattr on a existing dir with glusterfs.get_real_filename:<filename> as key should result in one of the following things. a. A value returned for that key having the real filename (a file whose match is a case insensitive match to the filename passed in key). b. op_ret = -1 and errno set to ENOENT meaning that no such file exists under the specified dir in any case. c. op_ret = -1 and errno set to ENODATA. This is a case assuming no xlator interprets the glusterfs.get_real_filename key and it get passed down to the posix xlator. Naturally, posix xlator would not find any xattr with this key and would return ENODATA. This will be interpreted specially by the caller as the feature not being supported by underlying glusterfs. 2. What assumptions are wrong? Initially the key used to be user.glusterfs.get_real_filename. In that case, when posix xlator did a getxattr call it would have received ENODATA as error. However, the key has now changed to glusterfs.get_real_filename. This leads to a EOPNOTSUPP error instead. Considering the above information, this is a rewrite of get_real_filename logic in dht.
