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.

Change in ...nfs-ganesha[next]: MDCACHE - Add MDCACHE {} config block
by Daniel Gryniewicz (GerritHub)
Daniel Gryniewicz has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/454929
Change subject: MDCACHE - Add MDCACHE {} config block
......................................................................
MDCACHE - Add MDCACHE {} config block
Add a config block name MDCACHE that is a copy of CACHEINODE. Both can
be configured, but MDCACHE will override CACHEINODE. This allows us to
deprecate CACHEINODE.

lseek gets bad offset from nfs client with ganesha/gluster which supports SEEK
by Kinglong Mee
The latest ganesha/gluster supports seek according to,
https://tools.ietf.org/html/draft-ietf-nfsv4-minorversion2-41#section-15.11
From the given sa_offset, find the next data_content4 of type sa_what
in the file. If the server can not find a corresponding sa_what,
then the status will still be NFS4_OK, but sr_eof would be TRUE. If
the server can find the sa_what, then the sr_offset is the start of
that content. If the sa_offset is beyond the end of the file, then
SEEK MUST return NFS4ERR_NXIO.
For a file's filemap as,
Part 1: HOLE 0x0000000000000000 ---> 0x0000000000600000
Part 2: DATA 0x0000000000600000 ---> 0x0000000000700000
Part 3: HOLE 0x0000000000700000 ---> 0x0000000001000000
SEEK(0x700000, SEEK_DATA) gets result (sr_eof:1, sr_offset:0x70000) from ganesha/gluster;
SEEK(0x700000, SEEK_HOLE) gets result (sr_eof:0, sr_offset:0x70000) from ganesha/gluster.
If an application depends the lseek result for data searching, it may enter infinite loop.
while (1) {
next_pos = lseek(fd, cur_pos, seek_type);
if (seek_type == SEEK_DATA) {
seek_type = SEEK_HOLE;
} else {
seek_type = SEEK_DATA;
}
if (next_pos == -1) {
return ;
cur_pos = next_pos;
}
The lseek syscall always gets 0x70000 from nfs client for those two cases,
but, if underlying filesystem is ext4/f2fs, or the nfs server is knfsd,
the lseek(0x700000, SEEK_DATA) gets ENXIO.
I wanna to know,
should I fix the ganesha/gluster as knfsd return ENXIO for the first case?
or should I fix the nfs client to return ENXIO for the first case?
thanks,
Kinglong Mee

V2.7.6 already contains 11e0e3, will try with eb98f5.
whence_is_name is false, so it's not a whence-is-name FSAL.
Thanks Dang.

Nothing directly related to the content lock. However, there have been
several use-after-free races fixed, and it's not impossible that trying
to interacte with a freed lock will cause a hang. The commits in
question are:
11e0e375e40658267cbf449afacaa53a136f7097
eb98f5b855147f44e79fe08dcec8d5057b05ea30
There have been quite a few fixes to readdir since 2.7.6 (and
specifically to whence-is-name; I believe your FSAL is a whence-is-name
FSAL?) so you might want to look into updating to a newer version.
2.8.4 should come out next week, and 3.3 soon after that.

Change in ...nfs-ganesha[next]: Move put_gsh_export(op_ctx->ctx_export) into op_context functions
by Frank Filz (GerritHub)
Frank Filz has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/491405 )
Change subject: Move put_gsh_export(op_ctx->ctx_export) into op_context functions
......................................................................
Move put_gsh_export(op_ctx->ctx_export) into op_context functions
To help enforce the lifetime of a gsh_export reference associated
with an op context, take care of releasing the reference in the
op context management functions.
Note that some of the removed put_gsh_export() calls do not have
op_ctx->ctx_export as the parameter, but looking at the code above
the export being put is in ctx_export anyway.
All of this paves the way for much simpler handling of refstr when
added to the export.

Change in ...nfs-ganesha[next]: EXPORT: Cleanup iniital refcounting and alloc/free of exports
by Frank Filz (GerritHub)
Frank Filz has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/491404 )
Change subject: EXPORT: Cleanup iniital refcounting and alloc/free of exports
......................................................................
EXPORT: Cleanup iniital refcounting and alloc/free of exports
Make alloc_export() return a reference. In all case, put_gsh_export can
safely be used to dispose of this reference and cause the export to be
ultimately freed.
With that, insert_gsh_export only adds the sentinel reference.
Move the init_op_context_simple in build_default_root to once the
export is as set up as much as if it was being built by the config
parser.
Since there is no longer a reason to explicitly call free_export just
pull the code into _put_gsh_export.
Also make sure that free_export_resources sets up an op context if
the export being released is not the one in op_ctx. Since that export
is already on it's way to death, just remove the export from the
op context which will have the effect of release_op_context for
a temporary op context NOT calling put_gsh_export in the future - it
doesn't need to since the refcount is already 0. This also assures that
if releasing the final refcount on the export in op_ctx, that op_ctx
is now poisoned.

Change in ...nfs-ganesha[next]: Add struct saved_export_context to standardize saving op_ctx bits
by Frank Filz (GerritHub)
Frank Filz has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/491403 )
Change subject: Add struct saved_export_context to standardize saving op_ctx bits
......................................................................
Add struct saved_export_context to standardize saving op_ctx bits
There are times when a process just wants to make a temporary export
change in the op_context but doesn't want to craft a whole new
op_context. This addition presents a standard way of saving the
export related bits of an op_context in order to be able to restore it
after the temporary change.

Assure and clarify references held for op_ctx->ctx_export
Some places were not holding a gsh_export reference for an export
referenced in op_ctx->ctx_export. Make sure that is true. Also
clarify the scope, using clear_op_context_export() if appropriate.
