I'd prefer not avoid having to convert all the nfs_fh and nfs_fattr structures to use dynamic allocation if at all possible. Removing the unused readdirplus-specific fields in struct nfs_entry is by far my first choice for a solution. Now that has been done, then we can start to worry about the remaining cases. So has anybody ever seen stack overflow errors in any of the other functions that allocate nfs_fh/nfs_fattr on the stack? That would be mainly in nfs_lookup() and nfs_lookup_revalidate().

Hi all,
[Please CC me in replies, I am not subscribed to the list.]
Since a few days, we have a serious kernel problem on one of our production
firewalls. It seems to be a problem in the interaction between openswan's
KLIPS, netfilter, and routing code, at least as fas as I see it. This problem
is reproducible on one system (we have not yet managed to figure out how to
reproduce it on another system) running kernel 2.4.32 with KLIPS 2.4.5 (and
pluto 2.4.5):

...
etc. The only unusual bit on this machine seems to be that there are SNAT
rules for traffic going into ipsec interfaces, i.e. with -A POSTROUTING -o
ipsec0. It runs 10 IPSec tunnels on 2 interfaces, 5 tunnels on each
interface.
Any ideas what might be wrong? Right now this is a critical problem for us,
and I would be happy about any pointer what to try. I can spare some time to
try and track it down. Currently, we try to remove the SNAT rules and work
around that, but as we can not trigger the problem (just wait for it to
happen, usually a few times a day), we can not reliably check if that fixes
it.
with best regards,
Rene

Hmm, but actually it shouldn't. Strange. > Is this similar to: > http://oss.sgi.com/archives/netdev/2004-12/msg00484.html? I read that thread, but I think it's not really applicable because: - I use IPSec, and according to the stack trace that seems to be part of the problem. - I still use kernel 2.4.32, so the patch given in that thread does not apply at all (I tried, but didn't look into the details). > Does your system continue to work after this, or does it flood your logs? No, it does not work - the only think that can be done is a complete (hardware) reset.
