Kernel Panics on OSX with aiccu
[nl] Shadow Hawkins on Friday, 17 April 2009 00:20:43
I have had several kernel panics the last few weeks, and I have only had em when I had aiccu running my ayiya tunnel . I have tried for a few days without aiccu and no kernel panics at all. I'm not a kernel log reader, but when I read route.c and rtunref, it sort of could be related to a ipv6 tunnel ? All the kernel panics I had where all with the same logfiles, maybe the problem is the tun/tap driver, but maybe someone could enlight me on that issue I'm running Mac OSX 10.5.6 and I have the self compiled from source aiccu. My tun/tap driver version I have no idea how to find out, my systemprofiler is not very verbose on the version. Here is the log: Mon Apr 13 18:26:48 2009 panic(cpu 0 caller 0x002232C6): "rtunref: bad refcnt 0 for rt=0x3e2dab0\n"@/SourceCache/xnu/xnu-1228.9.59/bsd/net/route.c:460 Backtrace (CPU 0), Frame : Return Address (4 potential args on stack) 0x3411fd28 : 0x12b4f3 (0x45b13c 0x3411fd5c 0x1335e4 0x0) 0x3411fd78 : 0x2232c6 (0x473df8 0x0 0x3e2dab0 0x0) 0x3411fd98 : 0x2237ba (0x3e2dab0 0x1 0x3411fde8 0x136713) 0x3411fdc8 : 0x224a66 (0x3e2dab0 0x2 0x8 0xf81a0120) 0x3411fde8 : 0x26c219 (0x3e2dab0 0x53076c 0x10 0x0) 0x3411fe68 : 0x229b69 (0x30135700 0x30135700 0x3411feb8 0x34ddd8c0) 0x3411fea8 : 0x34ddd1e4 (0x1e 0x30135700 0x3411fef8 0x34dda21d) 0x3411fec8 : 0x2151cf (0x5ec9204 0x1e 0x30135700 0x30135734) 0x3411fef8 : 0x21595b (0x52ad64 0x93b5808 0x30135734 0x3411ff4c) 0x3411ff68 : 0x215bb9 (0x0 0x30135700 0x0 0x52ade8) 0x3411ffc8 : 0x1a017c (0x52adc0 0x0 0x1a30b5 0x38953c8) Backtrace terminated-invalid frame pointer 0 Kernel loadable modules in backtrace (with dependencies): foo.tun(1.0)@0x34dd9000->0x34ddefff BSD process name corresponding to current thread: kernel_task Mac OS version: 9G55 Kernel version: Darwin Kernel Version 9.6.0: Mon Nov 24 17:37:00 PST 2008; root:xnu-1228.9.59~1/RELEASE_I386 System model name: MacBookPro2,2 (Mac-F42187C8)

Kernel Panics on OSX with aiccu

Really can't help you there. I suggest contacting Apple for this, it is their OS afterall. You might also want to check which TUN/TAP version you have and contact the people who maintain that.

I have reinstalled/updated the Tun/Tap driver, and so far so good. keep my fingers crossed, my hopes are that Jeroen Massar is right and it was not AICCU but the tun/tap driver causing the problems

In case AICCU could cause a kernel panick there would be something really wrong with security of Mac OS X. As that is not the case on that level (I hope), it has to be a kernel driver. Tun/Tap is that. Thus if there is anything that crashes, and thus includes wrong code that causes the crash it is there, or somewhere else in the kernel. Nothing AICCU can change though.
