COMMIT: https://review.gluster.org/19032 committed in release-3.12 by \"Yi Wang\" <wangyi8848> with a commit message- rpc-transport/rdma: Add a mutex for the list of RDMA Memory Region(MR) access Problem: gf_rdma_device_t->all_mr is a __gf_rdma_arena_mr(includes MR content) kind of list in the rdma rpc-transport. The rdma rpc-transport will add/delete items to the list when MRs register, deregister, and free. Because gf_rdma_device_t->all_mr is used by different threads and it is not mutex protected, rdma transport maybe access obsolete items in it. Solution: Add a mutex protection for the gf_rdma_device_t->all_mr. > Change-Id: I2b7de0f7aa516b90bb6f3c6aae3aadd23b243900 > BUG: 1522651 > Signed-off-by: Yi Wang <wangyi> (cherry picked from commit 8483ed87165c1695b513e223549d33d2d63891d9) Change-Id: I2b7de0f7aa516b90bb6f3c6aae3aadd23b243900 BUG: 1525850 Signed-off-by: Yi Wang <wangyi> This bug is getting closed because a release has been made available that should address the reported issue.
