Package: general Severity: normal The kernel panics when it receives a packet on an interface running the r8169 module that is of sufficient size.
To reproduce, have another host on the interface with MTU of 9000 to send a ICMP ping packet of size 9000, and then the driver will cause a panic. It seems the crash depends somewhat on the MTU of the r8169 interface as well as under some conditions there is no crash. I haven't had a chance to play around with this much because my only machine to test this with is running our file-server during business hours. Googling around seems to suggest that bugs like this have existed before: http://www.cvedetails.com/cve/CVE-2009-4537/ Is there any way to mitigate this problem? I can't exactly use my gigabit network to the fullest when all the machines have 1.5k MTUs to prevent this crash. -- System Information: Debian Release: 6.0.2 APT prefers stable APT policy: (700, 'stable'), (600, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.6.32-5-686 (SMP w/6 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
