Tweak parameters to decode_*, add a check or two, and thus gain most of the sanity improvements reyk@ recently put into dhcrelay to ensure no more than the captured packet is processed.

Changes since 1.9: +30 -7 lines
Diff to previous 1.9 (colored)
be very careful accepting packets via bpf. First check that the fixed part of the IP header is completely present before using its header length field. Then use the data in the IP header to ensure the entire IP packet is present. Then check that the entire UDP header is present. Then use the data in the UDP header to ensure all the data it thinks is present is actually present. Started when tj@ and a few others noticed ISC "DHCP CVE-2015-8605: UDP payload length not properly checked". ok sthen@ henning@

Fix very hard to reach DoS attack vector, which would involve more than 8 billion network packets. Mixture of many many malformed and proper packets could result in a division by zero. ok krw@

Remove unused (a.k.a. always passed NULL) parameter 'data' from decode_udp_ip_header() and the useless check of it. Part of original diff from pelikan about udp length errors.

Check UDP length field for short as well as long values. Fixes a dhcpd crash when a UDP packet arrives saying it has 0 length. Spotted by Martin Pelikan, who also noted it was fixed a while ago in ISC DHCP 3.0b2p17. Fix tested by Martin. Thanks!
