Description Ralph Böhme 2024-04-09 15:12:14 UTC 
Currently in some error code paths in the DH reconnect code we leave stale sharemode entries around that can lead to all sorts of havoc.
Comment 1 Ralph Böhme 2024-04-09 15:14:59 UTC 
Note, one way I've seen this happen is with a custom private VFS module stack that causes incorrect stat info in the cookie compared to the result from SMB_VFS_FSTAT() in the reconnect function.

Have patch, need bugnumber.
