Fixed In Version: ceph-16.2.10-176.el8cp
Doc Type: Bug Fix
Doc Text:
.Client programs no longer crash after releasing memory Previously, when releasing memory, the pointer access would be saved for future reference. This caused the programs to crash on the client-side. With this fix, memory is allocated and `UserPerm` contents are copied to newly allocated memory instead of saving pointers for future reference, thereby preventing the programs from crashing.
