Author: kp Date: Wed Aug 17 09:23:40 2016 New Revision: 304282 URL: https://svnweb.freebsd.org/changeset/base/304282 Log: MFC r302497: pf: Map hook returns onto the correct error values pf returns PF_PASS, PF_DROP, ... in the netpfil hooks, but the hook callers expect to get E<foo> error codes. Map the returns values. A pass is 0 (everything is OK), anything else means pf ate the packet, so return EACCES, which tells the stack not to emit an ICMP error message.
