2008-10-16* Allow ether_input() and vlan_input() to handle incoming packetsChristian Weisgerber
where the tag is stored in the mbuf header. * Make bridge(4) handle interfaces with and without hardware tag support and forward packets inbetween. Help and ok claudio@

2008-06-14add carppeer; an option to specify a different multicast address orReyk Floeter
even the unicast address of the remote carp peer. this especially helps when the multicast carp advertisements are causing problems in the network (some crappy switches don't do well with multicast), there are conflicts with VRRP, or the policy of the network does not allow multicast (most Internet eXchange points didn't allow carped OpenBGP routers because of the multicast advertisements). discussed with many ok mpf@

2008-05-07enable tx mitigation when putting packets on the wire by switching fromDavid Gwynne
calls to ifp->if_start to if_start(). these are the obviously right cases where we can do that, the less obvious ones may follow as theyre figured out. deraadt@ said to go for it
2008-04-24the softnet intr handlers check if the input queue has packets onDavid Gwynne
it by reading the queues head pointer. if that pointer is not null then it takes splnet and dequeues a packet for handling. this is bad because the ifqueue head is modified at splnet and the sofnet handlers read it without holding splnet. this removes that check of the head pointer and simply checks if the dequeue gave us a packet or not before proceeding. found while reading mpls code. discussed with norby@ and henning@ ok mcbride@ henning@

2007-05-28double pf performance.Henning Brauer
boring details: pf used to use an mbuf tag to keep track of route-to etc, altq, tags, routing table IDs, packets redirected to localhost etc. so each and every packet going through pf got an mbuf tag. mbuf tags use malloc'd memory, and that is knda slow. instead, stuff the information into the mbuf header directly. bridging soekris with just "pass" as ruleset went from 29 MBit/s to 58 MBit/s with that (before ryan's randomness fix, now it is even betterer) thanks to chris for the test setup! ok ryan ryan ckuethe reyk

2006-12-11refer to the RSTP point to point option as "PTP" instead of "P2P".Reyk Floeter
P2P is commonly used in relation to peer to peer networks, PTP is used in various protocols for layer 2 point to point links (ie., full duplex ethernet links). note that the newly added brconfig commands [-]p2p and [-]autop2p will change to [-]ptp and [-]autoptp. suggested by Andrew Thompson (thompsa@freebsd.org)
2006-12-03Add Rapid Spanning Tree Protocol support (802.1d-2004) based on workReyk Floeter
by Andrew Thompson (thompsa@freebsd.org). The local changes include adoption to our bridge code, reduced stack usage and many other bits. If stp is enabled, RSTP will now be used by default. Thanks for help from Andrew. This code has been in snaps for while now, commit encouraged by deraadt@

2003-08-15change arguments to suser. suser now takes the process, and a flagsTed Unangst
argument. old cred only calls user suser_ucred. this will allow future work to more flexibly implement the idea of a root process. looks like something i saw in freebsd, but a little different. use of suser_ucred vs suser in file system code should be looked at again, for the moment semantics remain unchanged. review and input from art@ testing and further review miod@
