Kernel crashes when repeatedly trying to mount nfs share that is failing
From Linux NFS
About
- Kernel version: 2.6.32, 2.6.37-rc3
- Bug 24302
- Reported by: Stefan Bader (December 3, 2010)
- Closed by: Florian Mickler (December 24, 2011)
How to reproduce
- ARCH: x86_64 (not tested on i386)
- On the server side, configure an export that will be denied to mount (used sec=krb5 as that gives a permission denied for me)
- server /etc/exports
/foo *(rw,krb5)
- On the client side, autofs gets configured to try to automount server:/foo
- client /etc/auto.master
/auto /etc/auto.auto
- client /etc/auto.auto
foo -tcp server:/foo
- Stop the autofs service and start the automounter in the foreground (automount -d -f) to see the permission denied message.
- Create a symlink pointing to the autofs:
ln -s /auto/foo foo
- The following is done in a loop as the crash sometimes takes longer than other times:
while true; do ls foo/ sleep 1 done
- It seems to take longer on the newest kernel, but eventually there will be a panic.
