Description of problem:
I am experiencing a kernel panic in very similar circumstances to a ticket on
the Netfilter bugzilla:
I have a Pentium 4 based system with four Marvell NICs using the sky2 driver.
One port is a standard interface for management of the box and two other form a
numbered bridge, br0. The third NIC is not used. One bridge interface and the
management interface are connected to a small hub.
Recently security scanning the management interface using the Qualys
vulnerability scanner a kernel panic would occur after only a few minutes of
scanning. A little investigation revealed the above bug in Netfilter.
So far I have rebuilt by own kernel and applied the fix suggested:
with additional change:
This fixes the kernel panic and the vulnerability scan proceeds to completion.
Version-Release number of selected component (if applicable):
Redhat Enterprise 4.4. Kernel 2.6.9-42.0.8 SMP.
Every time when performing a Qualys vulnerability scan.
Steps to Reproduce:
1. Run Qualys scan
2. Observe kernel panic
No Kernel Panic
If you need any further details such as packet traces etc, please let me know.
