Enabling ip forwarding when I have ip masquarading rules in the firewall
table crashes my machine immediately with a null pointer dereference, oops,
kernel panic inside interrupt handler, no sync. I experience an identical
failure condition in kernels 2.1.125, 126, 127, 128, 129, and 130. No more
than a handfull of packets pass through the masquarade before the machine
locks solid.
Here's my backtrace from 2.1.130:
c016ee14 t cleanup (EIP)
c016ee84 t ip_fw_check
c014fd74 t rtnetlink_fill_ifinfo
c0170448 T ipfw_forward_check
c010bc8c t read_long
c0106000 T get_options
c0100000 t startup_32
c0107310 T cpu_idle
c01075f4 T kernel_thread
Intel pr440fx motherboard, 2 PPro CPU's, SMP kernel. Using the onboard Intel
Etherexpress Pro/100 and a 3c59x card. I can swap out the 3c59x if it will
help me work around the problem, but the eepro/100 is built onto the
motherboard. I've attached my .config just in case the config rules allowed
me to select conflicting options or make an invalid configuration that's
responsible for my problems.
I'm interested to hear if anyone successfully masquarading with this
configuration or a similar one, or if anyone else has experienced the same
failure condition that I have. This system works OK with 2.0.36.
