* afs: Remove unused struct and function prototypeThorsten Blum2024-09-271-9/+0
| | | | | | | | | | | | | | | The struct afs_address_list and the function prototype afs_put_address_list() are not used anymore and can be removed. Remove them.

* afs: Fix possible infinite loop with unresponsive serversMarc Dionne2024-09-272-5/+10
| | | | | | | | | | | | | | | | | | | | | A return code of 0 from afs_wait_for_one_fs_probe is an indication that the endpoint state attached to the operation is stale and has been superseded. In that case the iteration needs to be restarted so that the newer probe result state gets used. Failure to do so can result in an tight infinite loop around the iterate_address label, where all addresses are thought to be responsive and have been tried, with nothing to refresh the endpoint state.

* pidfs: check for valid pid namespaceChristian Brauner2024-09-271-1/+4
| | | | | | | | | | | | | | When we access a no-current task's pid namespace we need check that the task hasn't been reaped in the meantime and it's pid namespace isn't accessible anymore. The user namespace is fine because it is only released when the last reference to struct task_struct is put and exit_creds() is called.

* afs: Fix missing wire-up of afs_retry_request()David Howells2024-09-271-0/+1
| | | | | | | | | | | | | | | | | | | | afs_retry_request() is supposed to be pointed to by the afs_req_ops netfs operations table, but the pointer got lost somewhere. The function is used during writeback to rotate through the authentication keys that were in force when the file was modified locally. Fix this by adding the pointer to the function.
