Change in ...nfs-ganesha[next]: Allow EXPORT pseudo path to be changed during export update

by Frank Filz (GerritHub)

Frank Filz has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/490334 ) Change subject: Allow EXPORT pseudo path to be changed during export update ...................................................................... Allow EXPORT pseudo path to be changed during export update This also fully allows adding or removing NFSv4 support from an export since we can now handle the PseudoFS swizzing that occurs. Note that an explicit PseudoFS export may be removed or added, though you can not change it from export_id 0 because we currently don't allow changing the export_id. Note that this patch doesn't handle DBUS add or remove export though that is an option to improve. I may add them to this patch (it wouldn't be that hard) but I want to get this reviewed as is right now. There are implications to a client of changing the PseudoFS. I have tested moving an export in the PseudoFS with a client mounted. The client will be able to continue accessing the export, though it may see an ESTALE error if it navigates out of the export. The current working directory will go bad and the pwd comment will fail indicating a disconnected mount. I have also seen referencing .. from the root of the export wrapping around back to the root (I believe this is how disconnected mounts are set up). FSAL_PSEUDO lookups and create handles (PUTFH or any use of an NFSv3 handle where the inode isn't cached) which fail during an export update are instead turned into ERR_FSAL_DELAY which turns into NFS4ERR_DELAY or NFS3ERR_JUKEBOX to force the client to retry under the completed update.

[M] Change in ...nfs-ganesha[next]: Check whether request is a real replay to warn kernel's bug

by liyinshu (GerritHub)

liyinshu has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/542321 ) Change subject: Check whether request is a real replay to warn kernel's bug ...................................................................... Check whether request is a real replay to warn kernel's bug If client use kernel 4.14.81 in https://kernel.org/, sometimes different requests share the same slot and sequenceid, ganesha thinks the latter request is a replay of former request, so return the response of the former request as the reply of the latter request. It can cause client hangs forever. For example, OP_SEQUENCE comes first, and then comes OP_GETATTR which share the same slot and sequenceid with the former OP_SEQUENCE, and ganesha reply NFS4ERR_RETRY_UNCACHED_REP. Then nfs-client will retry send the OP_GETATTR with the same slot and sequenceid, and ganesha still reply NFS4ERR_RETRY_UNCACHED_REP, ..., this will last forever. This bug, i.e. different requests share the same slot and sequenceid, disappers in kernel 5.4.143, fixed by some previous version.

[M] Change in ...nfs-ganesha[next]: Fix crash bcz slot->cached_result is null for replay request

by liyinshu (GerritHub)

To fix crash, move the code which need slot->cached_result from complete_op to nfs4_op_sequence, so thread1 can visit cached_result with the guard of slot->lock. Besides, we need to save cached_result's status in compound_data, so complete_op can get it.
