--nextPart6535353.WdSbsXgMfN Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Content-Disposition: inline Hi, while porting OpenBSD 3.9 (soon to be released) pf I stumbled on interface= =20 groups. This is a mechanism to group arbitrary interfaces into logical=20 groups. It is just naming (not functional change), but it helps to convey= =20 semantic information (e.g. group "LAN", "DMZ" ...) about your interface to= =20 supporting applications. This way you can write a policies for interface=20 group "LAN" and have it applied to all the VLAN interfaces that come and go= =2E =20 Administration is done via ifconfig. We currently have "ifconfig name" whi= ch=20 does part of the job. My question: Does that sound like something interesting for us and should I= go=20 for importing it into FreeBSD proper, or is it not at all interesting and w= e=20 don't want it (in which case I'd hack something up for pf). Technical reasoning: A proper import would add an additional TAILQ link in= to=20 struct ifnet (which is a great deal of ABI change and causes the usual=20 headaches). The hack would use a single void *, but we'd have to pay for t= he=20 additional indirection. Also yet another config tool would be required to= =20 administer the interface <-> group binding. =2D-=20 /"\ Best regards, | mlaier@freebsd.org \ / Max Laier | ICQ #67774661 X http://pf4freebsd.love2party.net/ | mlaier@EFnet / \ ASCII Ribbon Campaign | Against HTML Mail and News --nextPart6535353.WdSbsXgMfN Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (FreeBSD) iD8DBQBEKQJwXyyEoT62BG0RApLBAJ9XCNZefXFhdoOe2ddvvmnw8aERwgCeIojM 4j/m5sU8Qm7OP4FGAKDGMys= =64hZ -----END PGP SIGNATURE----- --nextPart6535353.WdSbsXgMfN--
