* glusterd: Brick process fails to come up with brickmux onVishal Pandey2020-03-171-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: 1- In a cluster of 3 Nodes N1, N2, N3. Create 3 volumes vol1, vol2, vol3 with 3 bricks (one from each node) 2- Set cluster.brick-multiplex on 3- Start all 3 volumes 4- Check if all bricks on a node are running on same port 5- Kill N1 6- Set performance.readdir-ahead for volumes vol1, vol2, vol3 7- Bring N1 up and check volume status 8- All bricks processes not running on N1. Root Cause - Since, There is a diff in volfile versions in N1 as compared to N2 and N3 therefore glusterd_import_friend_volume() is called. glusterd_import_friend_volume() copies the new_volinfo and deletes old_volinfo and then calls glusterd_start_bricks(). glusterd_start_bricks() looks for the volfiles and sends an rpc request to glusterfs_handle_attach(). Now, since the volinfo has been deleted by glusterd_delete_stale_volume() from priv->volumes list before glusterd_start_bricks() and glusterd_create_volfiles_and_notify_services() and glusterd_list_add_order is called after glusterd_start_bricks(), therefore the attach RPC req gets an empty volfile path and that causes the brick to crash. Fix- Call glusterd_list_add_order() and glusterd_create_volfiles_and_notify_services before glusterd_start_bricks() cal is made in glusterd_import_friend_volume > Change-Id: Idfe0e8710f7eb77ca3ddfa1cabeb45b2987f41aa > Bug: bz#1773856 > Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com> (cherry picked from commit 45e81aae791da9d013aba2286af44826227c05ec) Change-Id: Idfe0e8710f7eb77ca3ddfa1cabeb45b2987f41aa fixes: bz#1808964 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* glusterd: stop stale bricks during handshaking in brick mux modeAtin Mukherjee2020-03-164-9/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses two problems: 1. During friend handshaking, if a volume is imported due to change in the version, the old bricks were not stopped which would lead to a situation where bricks will run with old volfiles. 2. As part of attaching shd service in glusterd_attach_svc, there might be a case that the volume for which we're attempting to attach a shd service might become stale and in the process of deletion and hence in every retrials (if the rpc connection isn't ready) check for the existance of the volume and then only attempt the further attach request. patch on master: https://review.gluster.org/#/c/glusterfs/+/23042/ > Bug: bz#1733425 > Change-Id: I6bac6b871f7e31cb5bf277db979289dec196a03e > Signed-off-by: Atin Mukherjee <amukherj@redhat.com> > Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com> fixes: bz#1812849 Change-Id: I6bac6b871f7e31cb5bf277db979289dec196a03e Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* glusterd: fix use-after-free of a dict_tXavi Hernandez2019-09-151-1/+1
| | | | | | | | | | | | | | | | | | A dict was passed to a function that calls dict_unref() without taking any additional reference. Given that the same dict is also used after the function returns, this was causing a use-after-free situation. To fix the issue, we simply take an additional reference before calling the function. > Fixes: bz#1723890 > Change-Id: I98c6b76b08fe3fa6224edf281a26e9ba1ffe3017 > Signed-off-by: Xavi Hernandez <xhernandez@redhat.com> > (cherry picked from commit f36086db87aae24c10abde434f081d78b942735e) Fixes: bz#1752245 Change-Id: I98c6b76b08fe3fa6224edf281a26e9ba1ffe3017 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>

* event: rename event_XXX with gf_ prefixedXiubo Li2019-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I hit one crash issue when using the libgfapi. In the libgfapi it will call glfs_poller() --> event_dispatch() in file api/src/glfs.c:721, and the event_dispatch() is defined by libgluster locally, the problem is the name of event_dispatch() is the extremly the same with the one from libevent package form the OS. For example, if a executable program Foo, which will also use and link the libevent and the libgfapi at the same time, I can hit the crash, like: kernel: glfs_glfspoll[68486]: segfault at 1c0 ip 00007fef006fd2b8 sp 00007feeeaffce30 error 4 in libevent-2.0.so.5.1.9[7fef006ed000+46000] The link for Foo is: lib_foo_LADD = -levent $(GFAPI_LIBS) It will crash. This is because the glfs_poller() is calling the event_dispatch() from the libevent, not the libglsuter. The gfapi link info : GFAPI_LIBS = -lacl -lgfapi -lglusterfs -lgfrpc -lgfxdr -luuid If I link Foo like: lib_foo_LADD = $(GFAPI_LIBS) -levent It will works well without any problem. And if Foo call one private lib, such as handler_glfs.so, and the handler_glfs.so will link the GFAPI_LIBS directly, while the Foo won't and it will dlopen(handler_glfs.so), then the crash will be hit everytime. The link info will be: foo_LADD = -levent libhandler_glfs_LIBADD = $(GFAPI_LIBS) I can avoid the crash temporarily by linking the GFAPI_LIBS in Foo too like: foo_LADD = $(GFAPI_LIBS) -levent libhandler_glfs_LIBADD = $(GFAPI_LIBS) But this is ugly since the Foo won't use any APIs from the GFAPI_LIBS. And in some cases when the --as-needed link option is added(on many dists it is added as default), then the crash is back again, the above workaround won't work.

* glusterd/svc: update pid of mux volumes from the shd processMohammed Rafi KC2019-07-249-35/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a normal volume, we are updating the pid from a the process while we do a daemonization or at the end of the init if it is no-daemon mode. Along with updating the pid we also lock the file, to make sure that the process is running fine. With brick mux, we were updating the pidfile from gluterd after an attach/detach request. There are two problems with this approach. 1) We are not holding a pidlock for any file other than parent process. 2) There is a chance for possible race conditions with attach/detach. For example, shd start and a volume stop could race. Let's say we are starting an shd and it is attached to a volume. While we trying to link the pid file to the running process, this would have deleted by the thread that doing a volume stop.

* glusterd: do not mark skip_locking as true for geo-rep operationsSanju Rakonde2019-07-191-2/+7
| | | | | | | | | | | | | | | | | | We need to send the commit req to peers in case of geo-rep operations even though it is a no volname operation. In commit phase peers try to set the txn_opinfo which will fail because it is a no volname operation where we don't require a commit phase. We mark skip_locking as true for no volname operations, but we have to give an exception to geo-rep operations, so that they can set txn_opinfo in commit phase.

GD1 will be manipulated to consider replica count to be as 2 and continue creating the volume like any other replica 2 volume but since thin-arbiter volumes need ta-brick client xlator entries for each subvolume in fuse volfile, volfile generation is modified in a way to inject these entries seperately in the volfile for every subvolume. Few more additions - 1- Save the volinfo with new fields ta_bricks list and thin_arbiter_count. 2- Introduce a new option client.ta-brick-port to add remote-port to ta-brick xlator entry in fuse volfiles. The option can be set using the following CLI syntax - gluster volume set <VOLNAME> client.ta-brick-port <PORTNO.> 3- Volume Info will contain a Thin-Arbiter-path entry to distinguish from other replicate volumes.

| | | | | | | | | | | | | | | | | | | | Problem: While tier code was removed, the is_tier_enabled related to tier wasn't handled for upgrade. As this option was missing in the info file, the checksum mismatch issue happens during upgrade. This results in the peer rejections happening. Fix: use the op_version check and note down the is_tier_enabled always. This way it will be dummy key, but the future upgrades will work fine. NOTE: Just having the key from 3.10 to 7 will cause issues when upgraded from 5 to 8 or any such upgrade which skips the version where we handle it.

For example for shd, it should call glusterd_shdsvc_stop instead of calling basic API function to stop. Because the individual functions for each daemon could be doing some specific operation in their wrapper function.

* glusterd: add an op-version checkSanju Rakonde2019-05-311-1/+5
| | | | | | | | | | | | | | | | | | | | Problem: "gluster v status" is hung in heterogenous cluster when issued from a non-upgraded node. Cause: commit 34e010d64 fixes the txn-opinfo mem leak in op-sm framework by not setting the txn-opinfo if some conditions are true. When vol status is issued from a non-upgraded node, command is hanging in its upgraded peer as the upgraded node setting the txn-opinfo based on new conditions where as non-upgraded nodes are following diff conditions. Fix: Add an op-version check, so that all the nodes follow same set of conditions to set txn-opinfo. fixes: bz#1710159 Change-Id: Ie1f353212c5931ddd1b728d2e6949dfe6225c4ab Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

| | | | | | | | | | | | | | | Problem: In commit ac70f66c5805e10b3a1072bd467918730c0aeeb4 I missed one condition to populate volume dictionary in multiple threads while brick_multiplex is enabled.Due to that glusterd is not sending volume dictionary for all volumes to peer.
