Summary: NULL pointer dereference in ip_fragment
Product: Networking
Version: 2.5
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Other
AssignedTo: acme at ghostprotocols.net
ReportedBy: tom at dbservice.com
Regression: No
The host is using the ath9k driver. eth0+wlan0 are bridged. Shortly after I
start using the wireless network with my macbook, the bug triggers. No idea if
it's wireless related, because there's also a rtl8169_rx_interrupt entry in the
stacktrace.
This is a transcript, since I don't (have/know of) any way to get the backtrace
out of a crashed box.
IP: ip_fragment+0x52/0x840
Call Trace:
<IRQ>
br_parse_ip_options
br_flood_deliver
br_parse_ip_options
br_nf_dev_queue_xmit
br_nf_post_routing
nf_iterate
then also:
lots of br_flood_deliver
lots of br_*_finish
one ? rtl8169_interrupt
one ? ath9k_ioread32
