[PATCH 0/5] fyi, here are the patches that I haven't yet committed

[Ian Kent]

Let's try that again.

Not certain yet what the problem is but today I investigated a problem
reported against host map not working and it was something quite different.

There are a couple of patches here that are most likely needed in addition
to the currently committed patches.

In paticualar
autofs-5.0.8 - fix fix ipv6 libtirpc getport
autofs-5.0.8 - fix rpc_portmap_getport() proto not set
and possibly
autofs-5.0.8 - get_nfs_info() should query portmapper if port is not given

might be useful.

Remove a duplicated case entry and remove redundant check, since it
can never be reached, in rpc_rpcb_getport().

[Ian Kent]

From: Scott Mayhew <smayhew@redhat.com>

It shouldn't just assume it can use port 2049.

[PATCH 4/5] autofs-5.0.8 - fix rpc_portmap_getport() proto not set

[Ian Kent]

Recent changes to fix libtirpc usage problems when getting a server
exports list cause later server probing to fail.

When getting an exports list a new rpc client is always created for
the query, which includes setting the protocol in the parameters
structure. But when probing availability the client is reused where
possible and the protocol is not set in the parameters structure in
this case.

The rpc_portmap_getport() changes require that the protocol is set
in oder to function.

When checking for options in mount locations incorrect matches
can occur when the length of the option string is not also used
for the check.

Hi Ian:
  Do you mind push a temporary branch into your git repo (if you don't
want to queue other patches)?
That would much convenient for me to test.
  Thanks.

Try branch autofs-5.0.public.
As master and autofs-5.0 branches diverge the autofs-5.0 will be the
place for version 5.0.

Are you sure you're using the autofs-5.0.public branch.
That's the error I'd expect to see using master.

I put an entry with the same options into a map and tested it.
Worked fine for me.

What server are you using?
What kernel is on the server?
rpcbind or portmap?

HI Ian:
  finally, I have some time to try this..
  I have tested with autofs-5.0.7 and no problem when come to mount
nfs. but with 5.0.8(using branch autofs-5.0.public), automount crashed
(segmentfault)
  could you show me what's your "automount --version" there?

Hi Ian
  I've tested with various USE combinations,  still got segfault err.
wi all USE="-dmalloc -hesiod -ldap -libtirpc -mount-locking -sasl"
disabled, with libtirpc en/disabled.

 Next, I may need a few more time to setup gdb to investigate this..

also this patch needed to fix compile error while with libtirpc disabled,

sorry, I was not accurate about the failure cases.

using commit ec267c2c406256e401540e5bc890b2e0c2ff6c35

snip from file /etc/autofs/auto.misc
mkynfs -ro,soft,intr,nfsvers=3 192.168.90.12:/home/dennis
mkydns -ro,soft,intr,nfsvers=4 mickeycn:/home/dennis

with libtirpc enabled (all other features disabled),[1]
"ls /mnt/misc/mkynfs" lead to automount segfault
"ls /mnt/misc/mkydns" automount fail (no crash), but report "no hosts available"

with libtirpc disabled (all other features disabled)[2]
"ls /mnt/misc/mkynfs" automount fail (no crash), report "no hosts available"
"ls /mnt/misc/mkydns" works fine

Umm .. libtirpc disabled!
That's going to need work I think.

All of what's going on atm. is specifically for libtirpc so let me fix
that and then we can address side effects of the case when libtirpc is
disabled.

Right, I think I've worked out the issue with this second case.
I'll push my recent changes to autofs-5.0.public once I've had a look at
the segfault issue.

Mmmm .. I'll need to duplicate this and have a look.
The libtirpc disabled case shouldn't really have changed ....

Let me work through these logs and see if I can spot anything obvious.

I've updated the autofs-5.0.public branch.
Can you test it please.

Hi Ian:
 Did you only fix the problem while libtirpc is disabled, as I looking
at your commits?
I've tested the case with libtirpc disabled, all works fine (test both
nfs mount with nfsvers=3,4)

but with libtirpc enabled, fail as same previous error

I'm not able to reproduce those problems with the current source.
Tell me more (maybe again) about the server side.

Commit ec267c2c deals with a libtirpc failure that would result in the
"no hosts found" message and I'm not sure you had commit 7f7b730e either
which also caused failures.

Perhaps you could send a gdb backtrace, that might give ne a clue.
Run gdb on the core and capture the output of "thr a a bt".

What exactly does "all other features disabled" mean from a configure
POV. I always use --disable-mount-locking and --enable-ignore-busy,
always.

Maybe that's something to do with the problem your seeing .....

what more do you want to know?
it's also a gentoo system, using kernel 3.10.9-gentoo, server nfs-utils-1.2.9
