Change in ...nfs-ganesha[next]: Don't update fs_info.maxfilesize based on the backend.

by Solomon Boulos (GerritHub)

Solomon Boulos has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/487472 ) Change subject: Don't update fs_info.maxfilesize based on the backend. ...................................................................... Don't update fs_info.maxfilesize based on the backend. nlm_util (incorrectly) treats offsets > fs_info.maxfilesize as an opportunity to exit early. This was introduced in c811fe9323 to try to avoid waiting for errors downstream, except the cthon locking tests generate it and get the right answer (NFSD will happily let you specify UINT64_MAX as an offset). dang(a)redhat.com worked around this for the NFSv4 lock routines in 3d069bf, and we probably should do the same. For now though, I don't think other FSALs update fs_info.maxfilesize, so I'll just warn that we're not updating it.

Change in ...nfs-ganesha[next]: Implement basic NLM locking methods.

by Solomon Boulos (GerritHub)

Solomon Boulos has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/487471 ) Change subject: Implement basic NLM locking methods. ...................................................................... Implement basic NLM locking methods. Ganesha routes all NLM methods through the single lock_op2 handler, so I wired that up and did a "No, I can't handle async calls" implementation. This is good enough for a basic NLM LOCK as well as UNLOCK, but I don't think there's a great way for me to test the NLM_TEST op from the command line (without running either cthon or writing some basic fcntl code). Basic locking in action: # Terminal 1: Open a lockfile. $ flock proxy-mount/lockfile -c cat (Generates lockd: LOCK called on the backend server) # Terminal 2: See that Terminal 1's flock has the lockfile open. $ lsof proxy-mount/lockfile COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME flock 2149 boulos 3rW REG 0,38 0 541739 proxy-mount/lockfile cat 2151 boulos 3r REG 0,38 0 541739 proxy-mount/lockfile # Terminal 2: Try to grab the lockfile while it's held. $ flock -w 1 proxy-mount/lockfile -c echo ; echo $? 1 (Failed to acquire the lock within 1 second) # Terminal 1: Kill flock. $ Ctrl-C (Generates lockd: UNLOCK called on the backend server) I haven't written up / thought deeply yet about how reclaim and lock recovery are supposed to work. From a NFSv3 backend's (NFSD) perspective, the Ganesha proxy is its only "client". If the backend crashes, it will try to inform Ganesha, who will be fairly confused (Ganesha doesn't "know" that it's an NFS Client). If a client crashes, it will inform Ganesha's NFSD that it has crashed and try to reclaim. In theory, Ganesha's NFSD it totally prepared for that, because the state_lock code keeps track of the owners while the locks are held (they just happen to be held on the non-Ganesha backend too). Here's hoping.

Change in ...nfs-ganesha[next]: Ask the portmapper for the NLM port.

Change in ...nfs-ganesha[next]: Allow FSSTAT on any object.

Change in ...nfs-ganesha[next]: Error => warning for Ganesha's FSAL_DIGEST_V4 request.

by Solomon Boulos (GerritHub)

Solomon Boulos has uploaded this change for review.

Error => warning for Ganesha's FSAL_DIGEST_V4 request. The mdcache has a hardcoded "I want a FSAL_DIGEST_V4 from you", which I previously worked around with an innocuous ("V3 requests should be V3, V4 should be V4"). But, on "boot", there is no active operation / NFS request that drives the creation of the export, so the first one of these will fail. Not returning to Ganesha the handle to our root is sure to cause problems. So instead, since Ganesha doesn't look at it anyway, turn this into a warning. If possible, I may try to make the internal handler detect that it's being called for the root object and silently do that.
