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?

[L] Change in ...nfs-ganesha[next]: Malloc trim support
by Name of user not set (GerritHub)
Attention is currently required from: Malahal.
Hello Malahal,
I'd like you to do a code review.
Please visit
https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/547891
to review the following change.
Change subject: Malloc trim support
......................................................................
Malloc trim support
Glibc is known to cause greedy allocations with ganesha daemon, this
feature dynamically calls malloc_trim() to release memory back to the
system based on certain RSS (Resident Set Size) values. This feature
can be enabled by having "enable_trim = 1" in NFS_Core_Param{} block.
Also, it can be enabled/disabled by running:
ganesha_mgr trim enable OR
ganesha_mgr trim disable.
Its status can be queried with: ganesha_mgr trim status
ganesha_mgr trim call makes a one time malloc_trim(0) as well.

[S] Change in ...nfs-ganesha[next]: Fix race between nfs_rpc_call and nfs_rpc_call_process(callback).
by Sagar Singh (GerritHub)
Sagar Singh has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/547808 )
Change subject: Fix race between nfs_rpc_call and nfs_rpc_call_process(callback).
......................................................................
Fix race between nfs_rpc_call and nfs_rpc_call_process(callback).
If the callback (nfs_rpc_call_process) runs before the call
(nfs_rpc_call) finishes, it can hit use-after-free for the
"rpc_call_t" data structure shared between these. This change
uses a local callback channel pointer, in nfs_rpc_call to
avoid segmentation fault.

Fix up export initial config - need to try to pseudo mount all exports
Since we can't be sure of all export options until the point we are
actually building the pseudofs, we just add all exports into the
export mount work. Then pseudo_mount_export will verify using
export_can_be_mounted that looks at the EXPORT options, EXPORT_DEFAULTS
NFS_CORE_PARAM (for Protocols) and finally the code defaults.

ganesha_mgr: show clients failed with KeyError: '9P'
Suppose if ganesha not compiled with 9P, then ShowClients
dbus method will not return '9P' data. And, accessing '9P'
key in dict will fail with KeyError error.
Modified code to access dict key using get(). The get()
return default value if the key not exists in dict.
Default value is 0(zero).
