So I played a little more with the BUGgy kernel and I traked some simple actions to trigger the underflow: 0- boot at init 1 1- modprobe ipt_MASQUERADE Netfilter messages via NETLINK v0.30. ip_conntrack version 2.3 (2044 buckets, 16352 max) - 252 bytes per conntrack ip_tables: (C) 2000-2002 Netfilter core team 2- ifup eth0 e100: eth0: e100_watchdog: link up, 10Mbps, half-duplex BUG: atomic counter underflow at: [<d0c6738a>] ip_ct_iterate_cleanup+0xfa/0x100 [ip_conntrack] [<d0c441d3>] masq_inet_event+0x33/0x40 [ipt_MASQUERADE] [<d0c441e0>] device_cmp+0x0/0x40 [ipt_MASQUERADE] [<c012733d>] notifier_call_chain+0x2d/0x50 [<c02bea43>] inet_del_ifa+0x93/0x1d0 [<c02bf6af>] devinet_ioctl+0x4af/0x5a0 [<c02c1946>] inet_ioctl+0x66/0xb0 [<c0278be9>] sock_ioctl+0xc9/0x230 [<c016df2e>] do_ioctl+0x8e/0xa0 [<c02d5e08>] do_page_fault+0x188/0x613 [<c016e0f5>] vfs_ioctl+0x65/0x1f0 [<c016e2c5>] sys_ioctl+0x45/0x70 [<c0103185>] syscall_call+0x7/0xb 3- ifdown eth0 && ifup eth0 e100: eth0: e100_watchdog: link up, 10Mbps, half-duplex BUG: atomic counter underflow at: [<d0c6738a>] ip_ct_iterate_cleanup+0xfa/0x100 [ip_conntrack] [<d0c441d3>] masq_inet_event+0x33/0x40 [ipt_MASQUERADE] [<d0c441e0>] device_cmp+0x0/0x40 [ipt_MASQUERADE] [<c012733d>] notifier_call_chain+0x2d/0x50 [<c02bea43>] inet_del_ifa+0x93/0x1d0 [<c02bf6af>] devinet_ioctl+0x4af/0x5a0 [<c02c1946>] inet_ioctl+0x66/0xb0 [<c0278be9>] sock_ioctl+0xc9/0x230 [<c016df2e>] do_ioctl+0x8e/0xa0 [<c02d5e08>] do_page_fault+0x188/0x613 [<c016e0f5>] vfs_ioctl+0x65/0x1f0 [<c016e2c5>] sys_ioctl+0x45/0x70 [<c0103185>] syscall_call+0x7/0xb and that's all. So iflugd has not any influence here. -- mattia :wq! - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
