Malahal's change is sensible and consistent with the intent of the
code.  It actually fixes the UDP nsm behavior.

Not respecting the caller's choice of transports is a bug.

Fix rpmbuild failure if GANESHA_EXTRA_VERSION has a hyphen!

Commit 5e6fddbf1ae610a2041523ac8a3df8c62ab42ac8 removed only the first
hypen in the Release (aka GANESHA_EXTRA_VERSION).  If there are any
remaining hyphens in Release name, rpmbuild doesn't like it! Maybe we
should change how we name GANESHA_EXTRA_VERSION but for now, let us
remove first hyphen and then substitute remaining hyphens with with DOT.

[Nfs-ganesha-devel] v2.6-dev-4 leaves 271 threads hanging around

[William Allen Simpson]

Rather than spam the entire list, if anybody wants the gdb bt.  I can
send the ganesha.log, too, but it's bigger.

To test, rm the log, setup the libraries, gdb, run -F -- and on another
connection pkill ganesha.  Nothing else.  That's always my first test.

Well, my investigation should fix all versions.  After all, when the code
already explicitly says it wants TCP:

nsm_clnt = gsh_clnt_create("localhost", SM_PROG, SM_VERS, "tcp");

#15 0x71d311 in nsm_connect 
/export/nfs-ganesha/src/Protocols/NLM/nsm.c:55:13
#16 0x722ae9 in nsm_unmonitor_all 
/export/nfs-ganesha/src/Protocols/NLM/nsm.c:252:7

But ntirpc executes UDP instead:

#7 0x758e11c2 in clnt_dg_ncreate 
/export/nfs-ganesha/src/libntirpc/ntirpc/rpc/clnt.h:505:10
#8 0x758e0e64 in clnt_tli_ncreate 
/export/nfs-ganesha/src/libntirpc/src/clnt_generic.c:383:8

That surely looks like a serious bug to me!

Re: [Nfs-ganesha-devel] exporting cephfs as nfs share on RDMA transport

[William Allen Simpson]

On 8/14/17 1:31 PM, Raju  Rangoju wrote:

So, I was wondering maybe there is something else that needs to be configured 
for RDMA transport? Or Am I missing something? Can someone please provide some 
pointers on this.


RDMA was never completed.  It required a significant re-write of both
ntirpc and NFS-Ganesha.  That is still on-going.

Sadly, such things take a very long time around here.  For example, the
initial RDMA integration was done circa Feb 2015, but didn't make it into
the tree until Sep 2015.  That only worked for NFSv3 and only for short
setup and teardown.  To handle NFSv4 and large reads and writes required
much more work.

Re-organization that was done in Mar/Apr 2015 made it into the tree by
Feb/Mar this year.  Code that was written in May/Jun 2015 was integrated
last week.  And there's more to come

Our update to the RPC over RDMA specification was just published: RFC-8166.

Eventually the NFS RPC parsing will be re-written to provide a flag or
callback for NFS READ operations (that is, RDMA Write).

Plus all of the code-base must be re-written for async and zero-copy (the
whole purpose of RDMA).  That requires FSAL changes.

So we're a long way away.  The update to the interface requirements was
just handed off to the IESG LC:
