This could occasionally cause the rotation algorithm to drop straight through, give a 'successful' result without actually emitting any RPC calls, leaving the reply buffer in an undefined state. Instead, detach the probe results into a separate struct and allocate a new one each time we start probing and update the pointer to it. Probes are also sent in order of address preference to try and improve the chance that the preferred one will complete first. - Fix server rotation so that it uses configurable address preferences across on the probes that have completed so far than ranking them by RTT as the latter doesn't necessarily give the best route. The preference list can be altered by writing into /proc/net/afs/addr_prefs. - Fix the handling of Read-Only (and Backup) volume callbacks as there is one per volume, not one per file, so if someone performs a command that, say, offlines the volume but doesn't change it, when it comes back online we don't spam the server with a status fetch for every vnode we're using. Instead, check the Creation timestamp in the VolSync record when prompted by a callback break. - Handle volume regression (ie. a RW volume being restored from a backup) by scrubbing all cache data for that volume. This is detected from the VolSync creation timestamp. - Adjust abort handling and abort -> error mapping to match better with what other AFS clients do. - Fix offline and busy volume state handling as they only apply to individual server instances and not entire volumes and the rotation algorithm should go and look at other servers if available. Also make it sleep briefly before each retry if all the volume instances are unavailable" * tag 'afs-fix-rotation-20240105' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: (40 commits) afs: trace: Log afs_make_call(), including server address afs: Fix offline and busy message emission afs: Fix fileserver rotation afs: Overhaul invalidation handling to better support RO volumes afs: Parse the VolSync record in the reply of a number of RPC ops afs: Don't leave DONTUSE/NEWREPSITE servers out of server list afs: Fix comment in afs_do_lookup() afs: Apply server breaks to mmap'd files in the call processor afs: Move the vnode/volume validity checking code into its own file afs: Defer volume record destruction to a workqueue afs: Make it possible to find the volumes that are using a server afs: Combine the endpoint state bools into a bitmask afs: Keep a record of the current fileserver endpoint state afs: Dispatch vlserver probes in priority order afs: Dispatch fileserver probes in priority order afs: Mark address lists with configured priorities afs: Provide a way to configure address priorities afs: Remove the unimplemented afs_cmp_addr_list() afs: Add some more info to /proc/net/afs/servers rxrpc: Create a procfile to display outstanding client conn bundles ... |
