Now it's an IPSEC, tomorrow something else. I think all funct= ions that work with mbuf's should correctly handle unmapped mbuf's. But as a temporary patch, the solution proposed by kib@ is quite suitable. And m_unshare() should handle unmapped mbuf's correctly. --=20 You are receiving this mail because: You are the assignee for the bug.=
