Description Linda Wang 2005-07-27 22:29:52 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050512 Red Hat/1.0.4-1.4.1 Firefox/1.0.4

Description of problem:
This bug was fixed in ip_queue already, but the ipv6
variant was overlooked at that time.

We have to explicitly disable software interrupts, else the locking in
the nf_reinject() path will end up potentially deadlocking with any
intervening software interrupt.



Version-Release number of selected component (if applicable):
kernel-2.6.9

How reproducible:
Always

Steps to Reproduce:
1.boot kernel
2.setup with IPV6
3.
