NFS4+KRB5 trouble in Kernel >3.8

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

seems I have been bitten again by the same Problem as back in November
(http://comments.gmane.org/gmane.linux.nfs/52916).

Well, at least the symptoms are the same. The problem is almost
certainly another one.

In recent kernels (e.g. 3.9.4) again my mount seems to hang infinitely:

mount -t nfs4 -o sec=krb5 testsrv:/storage /mnt/tmp 

This time I immediately tried to bisect this, but what happens is that half
the way down bisecting the symptoms change. The mount does not hang anymore,
but I get "access denied" now:

 ~/ # mount -t nfs4 -o sec=krb5 testsrv:/storage /mnt/tmp
mount.nfs4: access denied by server while mounting testsrv:/storage

So how to continue bisecting? Should I mark this as good or bad?

Here is the output of "git bisect log" so far:

git bisect start
# good: [dbf932a9b316d5b29b3e220e5a30e7a165ad2992] Linux 3.8.13
git bisect good dbf932a9b316d5b29b3e220e5a30e7a165ad2992
# bad: [0bfd8ffeff9dda08c69381d65c72e0aa58706ef6] Linux 3.9.4
git bisect bad 0bfd8ffeff9dda08c69381d65c72e0aa58706ef6
# good: [19f949f52599ba7c3f67a5897ac6be14bfcb1200] Linux 3.8
git bisect good 19f949f52599ba7c3f67a5897ac6be14bfcb1200
# good: [ef53d16cded7f89b3843b7a96970dab897843ea5] ksm: allocate roots when needed
git bisect good ef53d16cded7f89b3843b7a96970dab897843ea5

I did not mark the current state with either good or bad yet.

Regards

Sven
