mav 2008-09-13 09:17:02 UTC FreeBSD src repository Modified files: sys/netgraph ng_base.c Log: SVN rev 182995 on 2008-09-13 09:17:02Z by mav We can't implicitly trust the hook on NGQF_FN/NGQF_FN2 processing in ng_apply_item(). There are possible (and I have got one) use-after-free class panics because of it. If hook is specified, require it to be valid at the apply time. The only exceptions are the internal ng_con_part2(), ng_con_part3() and ng_rmhook_part2() functions which are specially made to work with invalid hooks. Revision Changes Path 1.163 +14 -6 src/sys/netgraph/ng_base.c
