Openafs packages have been updated to 1.9.1 for various bugfixes, and added a fix for security vulnerability:
There exist in the wild AFS3 clients that improperly construct access control lists which are then stored to directories via RXAFSStoreACL (opcode 134). These clients add negative access control entries (if any) to the normal rights list. As there is no method by which a fileserver can determine that the ACL is improperly constructed, the only method to defend the storage of broken ACLs is to identify clients that are known to properly construct ACLs by introducing a new RXAFSStoreACL opcode (164) (CVE-2018-7168).
Additionally the CellServDB has been updated to latest version and fixes for suppoorting kernel 5.14 and 5.15 series have been added.
