* features/snapview-server: validate the fs instance before doing fop thereRaghavendra Bhat2018-08-243-30/+120
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: ======== USS design depends on snapview-server translator communicating with each individual snapshot via gfapi. So, the snapview-server xlator maintains the glfs instance (thus the snapshot) to which a inode belongs to by storing it inside the inode context. Suppose, a file from a snapshot is opened by a application, and the fd is still valid from application's point of view (i.e. application has not yet closed fd). Now, if the snapshot to which the opened file belongs to is deleted, then the glfs_t instance corresponding to the snapshot is destroyed by snapview-server as part of snap deletion. But now, if the application does IO on the fd it has kept open, then snapview server tries to send that request to the corresponding snap via glfs instance for that snapshot stored in the inode context for the file on which the application is sending the fop. And this results in freed up glfs_t pointer being accessed and causes a segfault. FIX: === For fd based operations, check whether the glfs instance that the inode contains in its context, is still valid or not. For non fd based operations, usually lookup should guarantee that. But if the file was already looked up, and the client accessing the snap data (either NFS, or native glusterfs fuse) does not bother to send a lookup and directly sends a path based fop, then that path based fop should ensure that the fs instance is valid.

* performance/write-behind: fix fulfill and readdirp raceRaghavendra G2018-08-231-33/+136
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current invalidation of stats in wb_readdirp_cbk is prone to races. As the deleted comment explains, <snip> We cannot guarantee integrity of entry->d_stat as there are cached writes. The stat is most likely stale as it doesn't account the cached writes. However, checking for non-empty liability list here is not a fool-proof solution as there can be races like, 1. readdirp is successful on posix 2. sync of cached write is successful on posix 3. write-behind received sync response and removed the request from liability queue 4. readdirp response is processed at write-behind. In the above scenario, stat for the file is sent back in readdirp response but it is stale. </snip> The fix is to mark readdirp sessions (tracked in this patch by non-zero value of "readdirps" on parent inode) and if fulfill completes when one or more readdirp sessions are in progress, mark the inode so that wb_readdirp_cbk doesn't send iatts for that in inode in readdirp response. Note that wb_readdirp_cbk already checks for presence of a non-empty liability queue and invalidates iatt. Since the only way a liability queue can shrink is by fulfilling requests in liability queue, wb_fulfill_cbk indicates wb_readdirp_cbk that a potential race could've happened b/w readdirp and fulfill.

* glusterd: glusterd_brick_start shouldn't try to bring up brick if ↵Atin Mukherjee2018-08-231-0/+4

Nuked an unnecessary log message upon error as well since failure logging is being done in the caller - 1124772: Memory leak in an error path of glusterd_op_ac_send_brick_op() - 1175021: Removed an unessential variable that caused a memory leak in glusterd_op_build_payload() Also addressed a memory leak in an error path of glusterd_dict_set_volid() Change-Id: I060effbbcebe9d58b91f606175080ede517ba239 updates: bz#789278 Signed-off-by: Vijay Bellur <vbellur@redhat.com>

* snapshot : fix snapshot status failure due to symlink problemSunny Kumar2018-08-231-1/+9
| | | | | | | | | | | | | | | | | | | | | | | Problems : 1. Snapshot status for individual snapshots were failing after OS upgrade from RHEL6 to RHEL7. 2. Post upgrade snapshot creation of cloned volume was failing. Root Cause : When OS upgrade is from RHEL6 to RHEL7 there is difference in symlink (/var/run) between these two versions. Basically when (/var/run) is symlinked to /run, mount command resolves path and mounts it. But at the same time call to those functions fails who depends on absolute path. (like strcmp in glusterd_get_mnt_entry_info) Solution : Resolve the input path to absolute path before calling these functions. Test : Tested on same setup where issue was reported. After this patch snapshot issues are completely resolved. Change-Id: I5ba57998cea614c6072709f52f42a57562018844 fixes: bz#1619843 Signed-off-by: Sunny Kumar <sunkumar@redhat.com>

* xlators: protocol: Fix deferencing pointer after free coverity issuesBhumika Goyal2018-08-213-32/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | The pointer of type struct iobuf * is getting dereferenced after getting freed by iobuf_unref function. Therefore, move this function after all the dereferences of this pointer type. Also, it is useful coding standard to have iobuf_unref just after iobref_add. So, move iobref_add too. Occurences found using Coccinelle script: @@ identifier rsphdr_iobuf; expression E; identifier func; @@ *iobuf_unref(rsphdr_iobuf); ... *E = func(rsphdr_iobuf); Fixes CID: 1390517, 1390278, 1388666, 1356588, 1356587 at [1]. and also some more occurences which were found using the above script but not caught by Coverity.
