In some cases, removed redundant strlen() calls by saving the result into a variable. 1. Only done for the straightforward cases. There's room for improvement. 2. Please review carefully, especially for string allocation, with the terminating NULL string.

* glusterd: fail volume stop operation if brick detach failsAtin Mukherjee2018-09-041-8/+22
| | | | | | | | | | | | | | While sending a detach request for a brick in brick multiplexing mode, in any situation if the brick isn't connected, glusterd will fail to detach the brick but due to the missing error code handling, glusterd will mark the volume as stopped. Fix is to handle the return code of send_attach_req in glusterd_volume_stop_glusterfs () Change-Id: I886202969c96eec3620f74cd7027652d6287f4be Fixes: bz#1624440 Signed-off-by: Atin Mukherjee <amukherj@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | 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>

* glusterd: ignore importing volume which is undergoing a delete operationAtin Mukherjee2018-08-165-6/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem explanation: Assuming in a 3 nodes cluster, if N1 originates a delete operation and while N1's commit phase completes, either glusterd service of N2 or N3 gets disconnected from N1 (before completing the commit phase), N1 will attempt to end up importing the volume which is in-flight for a delete in other nodes as a fresh resulting into an incorrect configuration state. Fix: Mark a volume as stage deleted once a volume delete operation passes it's staging phase and reset this flag during unlock phase. Now during this intermediate phase if the same volume gets imported to other peers, it shouldn't considered to be recreated. An automated .t is quite tough to implement with the current infra. Test Case: 1. Keep creating and deleting volumes in a loop on a 3 node cluster 2. Simulate n/w failure between the peers (ifdown followed by ifup) 3. Check if output of 'gluster v list | wc -l' is same across all 3 nodes during 1 & 2.

* glusterd: compare friend data within mutexAtin Mukherjee2018-08-133-41/+48
| | | | | | | | | | | | | | | | | | | | | | | During friend handshake if the glusterd receives more than one friend updates, it might very well become possible that two threads would end up working on two different volinfo references and glusterd might end up updating the store with a old volinfo reference. While debugging glusterd crash from validating-server-quorum.t test file from the line-coverage regression the same was observed. Solution is to run glusterd_compare_friend_data under a mutex. Test: As the crash was more visible in the line-coverage run (given lcov does some instrumentation and exposes the races), 6 manual lcov runs were triggered starting from https://build.gluster.org/job/line-coverage/443 to https://build.gluster.org/job/line-coverage/449/ and no crash was observed from validating-server-quorum.t Change-Id: I86fce473a76fd24742d51bf17a685d28b90a8941 Fixes: bz#1603063 Signed-off-by: Atin Mukherjee <amukherj@redhat.com>
