Doc Type: Bug Fix
Doc Text:
.`rbd_support` module no longer fails to recover from repeated blocklisting of its client Previously, it was observed that the `rbd_support` module failed to recover from repeated blocklisting of its client due to a recursive deadlock in the rbd_support module, a race condition in the rbd_support module's librbd client, and a bug in the librbd cython bindings that sometimes crashed the ceph-mgr. With this release, all these 3 issues are fixed and rbd_support` module no longer fails to recover from repeated blocklisting of its client

Description Ram Raja 2023-11-01 20:35:44 UTC 
Tested the recovery of the rbd_support module on repeated blocklisting of its client (https://bugzilla.redhat.com/show_bug.cgi?id=2111364) using the integration test in https://tracker.ceph.com/issues/62891 . Over tens of runs of the integration test (in upstream Ceph teuthology infra), ~40% of the runs failed. Observed hangs and ceph-mgr crashes when the rbd_support module tried to recover. Note that a hang during recovery was fixed earlier in https://bugzilla.redhat.com/show_bug.cgi?id=2211290 . The remaining hangs and ceph-mgr crash were root caused in
