Such already exists, as in_cksum.c in the hardware specific junk (such as /usr/src/sys/i386/i386/in_cksum.c). A more useful feature might be a socket which you can bind to a specific interface and then be able to send raw frames (or whatever the data link layer method might be) without the overhead of raw_output, ip_output, routing table lokups, etc. -- Richard Steenbergen <humble@lightning.net> humble@EFNet PGP ID: 0x741D0374 PGP Key Fingerprint: C6EF EFA0 83B2 071F 1AB6 B879 1F70 4303 741D 0374 http://users.quadrunner.com/humble To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
