Bug 352628 – sys-kernel/gentoo-sources-2.6.37 kernel dump for xt_recent operation

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description andcycle-gentoo 2011-01-24 19:39:09 UTC]

I am not actually know how to write a correct bug report for kernel,
here is what I found with xt_recent

Reproducible: Always

Steps to Reproduce:
1. modprobe xt_recent ip_list_tot=32767 ip_pkt_list_tot=2
2. insert some table rule with xt_recent rcheck/update with multiple xt_recent name
3. do "echo +" alot ip address into " >/proc/net/xt_recent/blabla"
4. batch those ip just addded with "echo -" to remove them, interleave with iptables delete
5. get some kernel dump, system is still working

Actual Results:  
here is the dmesg
