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.

Help needed on FD
by Alok Sinha
FD created at below path does not have correct link in /proc/self/fd.
With vfs_readlink_by_handle , I can get a relative path but cannot get the
absolute path of the FD.
I need a suggestion for one of the below to get around a production bug:
- How to get the full path of the FD?
- How to get the parent vfs_fsal_obj_handle?
- Anyway to bypass this flow by changing any config file?

[XS] Change in ...nfs-ganesha[next]: build: Fix developer warning for LSB module
by Martin Schwenke (GerritHub)
Martin Schwenke has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/554766?usp=email )
Change subject: build: Fix developer warning for LSB module
......................................................................
build: Fix developer warning for LSB module
CMake Warning (dev) at /usr/share/cmake-3.25/Modules/FindPackageHandleStandardArgs.cmake:438 (message):
The package name passed to `find_package_handle_standard_args`
(LSB_RELEASE) does not match the name of the calling package (LSB). This
can lead to problems in calling code that expects `find_package` result
variables (e.g., `_FOUND`) to follow a certain pattern.
Call Stack (most recent call first):
cmake/modules/FindLSB.cmake:85 (find_package_handle_standard_args)
CMakeLists.txt:1632 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.
Rename the module to LSBRelease and make that the first argument to
find_package_handle_standard_args().
Other options are:
* Pass LSB as the first argument. This just seems confusing.
* Rename the module to LSB_RELEASE. Given that there are no cmake
modules with names containing underscores, this doesn't seem like
the right solution.

[L] Change in ...nfs-ganesha[next]: build: Fix Python detection
by Martin Schwenke (GerritHub)
Martin Schwenke has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/554765?usp=email )
Change subject: build: Fix Python detection
......................................................................
build: Fix Python detection
Commit c43049fc42b0a1d39b48ddbf93af56223ba5f9ee introduced copies of
several cmake modules, which are now breaking Python detection. The
commit message does not give details of benefits of these versions of
the modules. It is unclear if they were different to the upstream
cmake modules at the time and this can't be resolved without an
archaeological dig. Whatever the case, the modules have almost
certainly been improved upstream to work around the reason for their
addition here.
Just delete the duplicate modules introduced by the above commit.
This leaves src/cmake/modules/FindGTest.cmake as the only apparent
duplicate module.
Note that this change introduces a developer warning:
CMake Warning (dev) at /usr/share/cmake-3.25/Modules/FindPackageHandleStandardArgs.cmake:438 (message):

cmake/modules/FindLSB.cmake:85 (find_package_handle_standard_args)
CMakeLists.txt:1632 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.
Given that this is only a warning, this can be fixed in a subsequent
commit.

GPFS: fix 40 byte sized old file handles
Some versions may have returned 40 byte sized file handles. Make them
same as 48 byte sized file handles to avoid multiple entries in the
object cache for the same file system object.

MDCache LRU management queries
by Gaurav Sharma
Hi Ganesha Team,
In MDCache we have two arrays named LRU and CHUNK_LRU to store the lru
entry in their respective queues.
For the CHUNK_LRU, the function lru_bump_chunk() will move the entry to MRU
of L1.
For LRU there is a function adjust_lru() which does the similar job.
Question : The function adjust_lru() is only called if the flag
is LRU_REQ_INITIAL and that is happening only during unexport.
1. Can you please suggest how the entries in LRU queue are moving to MRU
of the queue?
2. How LRU entries are moved from L2 to L1 queue? from L1 to L2 is done
by the background thread.
Regards,
Gaurav Sharma

Pass failure to add clientid to recovery database back to client
Previously we would log an error, but leave the client with no

a server failure.
The failure will be reported to the client as NFS4ERR_SERVERFAULT

Change subject: For async I/O the callback must create it's own op_context
......................................................................
For async I/O the callback must create it's own op_context
We can't pass the orginal caller's op_context, it may still need it.
Just instantiate a simple op_context for the callback.
The callback op_context needs an export reference but we can take
it when we create the op_context because until the protocol callback
is made, we know the protocol request's op_context with its reference
for the export MUST still be valid.
