Hi, nfs client is defunct in this kernel. Tcpdump says:

If I run the same mount command (mount -oro,intr host:dir mountpoint)
from within a virtual machine with 2.6.38.2 there, everything mounts OK.

The next tree from 20110411 still doesn't work. The topmost commit in
fs/nfs/namespace.c is:

    NFS: Fix a signed vs. unsigned secinfo bug


I bisected it to (in vanilla already):

8f70e95f9f4159184f557a1db60c909d7c1bd2e3 is the first bad commit

    NFS: Determine initial mount security

    When sec=<something> is not presented as a mount option,
    we should attempt to determine what security flavor the
    server is using.

Does this patch help?

- Bryan

When attempting an initial mount, we should only attempt other
authflavors if AUTH_UNIX receives a NFS4ERR_WRONGSEC error.
This allows other errors to be passed back to userspace programs.

Sorry for an extra message. I've just found out that there appears
messages in dmesg:

I instrumented the code and it's stuck with trying RPC_AUTH_GSS_KRB5.

I don't use GSS at all.

No, the patch fixes a problem I have after I add the following test here:
                if (flav_array[i] > 100)
                        continue;

Without this test it still loops inside gss auth create function with:
RPC: AUTH_GSS upcall timed out.

Does this patch help?

- Bryan



There can be an infinite loop if gss_create_upcall() is called without
the userspace program running.  To prevent this, we return -EACCES if
we notice that pipe_version hasn't changed (indicating that the pipe
has not been opened).

Yes, it fixes the problem. But it waits 15s before it times out. This is
inacceptable for automounted NFS dirs.

I'm still confused as to why you are hitting it at all. In the normal
autonegotiation case, the client should be trying to use AUTH_SYS first
and then trying rpcsec_gss if and only if that fails.

Are you really exporting a filesystem using AUTH_NULL as the only
supported flavour?

I don't know, I connect to a nfs server which is not maintained by me.
It looks like that. How can I find out?

A wireshark trace of a successful mount would help.

If you're not using gss for anything, you could try rmmod-ing rpcsec_gss_krb5 (and other rpcsec_gss_* modules).

I don't have NFS in modules. It's all built-in. And this one is
unconditionally selected because of CONFIG_NFS_V4.

Does this patch help?

- Bryan

We should attempt an AUTH_NULL style mount before
trying gss flavors.  This should prevent a hang if
gss modules are loaded but the userspace program
isn't running.

Nope, it makes things even worse:
# mount -oro,intr XXX:/yyy /mnt/c/
<15s delay here>
mount.nfs: access denied by server while mounting XXX:/yyy

So in nfs4_proc_get_root I do:
  printk("%s: %d %u\n", __func__, i, flav_array[i]);
  status = nfs4_lookup_root_sec(server, fhandle, info, flav_array[i]);
  printk("%s: res=%d\n", __func__, status);
and get:
[   18.159818] nfs4_proc_get_root: 0 1
[   18.214872] nfs4_proc_get_root: res=-1
[   18.214875] nfs4_proc_get_root: 1 0
[   18.254636] nfs4_proc_get_root: res=-1
[   18.254639] nfs4_proc_get_root: 2 390003

[   33.252177] Please check user daemon is running.
[   33.252192] nfs4_proc_get_root: res=-13

If I revert that back and do the same:
[   28.275569] nfs4_proc_get_root: 0 1
[   28.296545] nfs4_proc_get_root: res=-1
[   28.296548] nfs4_proc_get_root: 1 390003
[   43.296107] RPC: AUTH_GSS upcall timed out.
[   43.296108] Please check user daemon is running.

[   43.296122] nfs4_proc_get_root: 2 0
[   43.318201] nfs4_proc_get_root: res=-1

I.e. all methods fail. And what matters is the last retval. From NULL it
is EPERM, from GSS it is EACCESS. For EPERM, mount(8) falls back to
nfs3, for EACCESS it dies terrible death.

OK. That's good information. Thanks for testing!

I'm still curious as to why that NFS server is refusing all NFSv4 mounts
with NFS4ERR_WRONGSEC. Unless NFSv4 really is configured only to export
the root filesystem with RPCSEC_GSS, then that definitely sounds like a
bug...
