Here is more information:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xb2c04400
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc0199fa0
stack pointer = 0x10:0xc020c218
frame pointer = 0x10:0xc020c268
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = Idle
interrupt mask = net tty
kernel: type 12 trap, code=0
Stopped at esp_hdrsiz+0x498: movl 0(%edx),%eax
So, the problem seems to be in the IPsec code, sys/netinet6/esp_output.c
called from sys/netinet6/ipsec.c. Here is the stack trace:
esp_hdrsiz(c0b48500,c0b485f5,c0b3f400,c0ceb800,2) at esp_hdrsiz+0x498
esp4_output(c0b48500,c0ceb800,c0ceba00,0,1) at esp4_output+0x48
ipsec4_output(c020c418,c0ceba00,1,c0ceef00,c0b5af00) at ipsec4_output+0x2e3
ip_output(c0b1be00,0,c0229a50,1,0) at ip_output+0x762
ip_stripoptions(c0b1be00,0,c0b1be00,0,ffffffff) at ip_stripoptions+0x211
ip_input(c0b1be00) at ip_input+0x462
ip_input(c01d374f,0,d0f0010,10,c7a50010) at ip_input+0x7b7
doreti_popl_fs_fault() at doreti_popl_fs_fault+0x91
I am assuming if I upgrade to some more current version of the IPsec
code the problem might have been fixed. But am not sure... I will
report more later.
thanks
