src/sys/netipsec: xform_ipip.c
Log Message:
Fix use-after-free. There is a path where the mbuf gets pulled up without
a proper mtod afterwards:
218 ipo = mtod(m, struct ip *);
281 m = m_pullup(m, hlen);
232 ipo->ip_src.s_addr
Found by Mootja.
Meanwhile it seems to me that 'ipo' should be set to NULL if the inner
packet is IPv6, but I'll revisit that later.
