Hey folks, I'm working on getting miniupnpd building in pkgsrc.   I've got
it building but running it inside a zone kills the machine (not just the
VM).   I'm a SmartOS kernel debugging noob so what info could I get that
would help diagnose this?   I loaded up the dump into mdb - here's the
crashing callstack:

> $C

ffffff003d236140 ipf_unlinktoken+0x2f(ffffff0933cccde0, ffffff091e90a000)

ffffff003d236190 ipf_freetoken+0x29(ffffff0933cccde0, ffffff091e90a000)

ffffff003d236600 nat_getnext+0x3d9(ffffff0933cccde0, ffffff003d236840,
ffffff091e90a000)

ffffff003d236630 nat_iterator+0x4c(ffffff0933cccde0, ffffff003d236840,
ffffff091e90a000)

ffffff003d2368c0 fr_nat_ioctl+0x69a(fffffd7fffdfb360, c038725d, 202003, 0,
ffffff0933835050, ffffff091e90a000)

ffffff003d236900 fr_ioctlswitch+0xd7(1, fffffd7fffdfb360, c038725d, 202003,
0, ffffff0933835050, ffffff091e90a000)

ffffff003d236cc0 iplioctl+0x131(bb00000003, c038725d, fffffd7fffdfb360,
202003, ffffff0932f524a0, ffffff003d236ea8)

ffffff003d236d00 cdev_ioctl+0x39(bb00000003, c038725d, fffffd7fffdfb360,
202003, ffffff0932f524a0, ffffff003d236ea8)

ffffff003d236d50 spec_ioctl+0x60(ffffff0929046640, c038725d,
fffffd7fffdfb360, 202003, ffffff0932f524a0, ffffff003d236ea8, 0)

ffffff003d236de0 fop_ioctl+0x55(ffffff0929046640, c038725d,
fffffd7fffdfb360, 202003, ffffff0932f524a0, ffffff003d236ea8, 0)

ffffff003d236f00 ioctl+0x9b(3, c038725d, fffffd7fffdfb360)

ffffff003d236f10 sys_syscall+0x17a()


I can provide the miniupnpd package (or the patches I made to it) to help
repro if that'd help.   If there's somewhere I can upload the dump, I can
do that as well.

Thanks.

-John
