2005-01-14Add kernel support for Protocol Independant Multicast (PIM)Ryan Thomas McBride

2005-01-10Make sure bogus values don't make their way into tcp_xmit_timer() calculations.Ryan Thomas McBride
- Ignore ts_ecr if it is 0, or the resulting rtt is out of range. (use tp->t_rtttime instead) - Initialise tcp_now to 1, to avoid the 500ms window where a valid ts_ecr of 0 could be ignored. - Convert out-of-range rtt values to valid ones in tcp_xmit_timer(). ok frantzen@ markus@

2005-01-06Attach multicast to the carp interface for IPv6 (makes it consistent withRyan Thomas McBride
IPv4, and will allow us to get rid of carp_fix_lladdr() and the carp mbuf tag later). ok pascoe@ mpf@
2005-01-06Error path cleanups for carp_output. Use ENOBUFS instead of ENOMEM whenChristopher Pascoe
unable to tag a packet, and free mbuf chain on all failures. ok mcbride@
2005-01-06Tag all packets sent via a CARP interface for link local addressChristopher Pascoe
substitution. With this change and the previous ARP changes, all Ethernet packets sent via a CARP interface should now have the virtual MAC address as the source. ok mcbride@ niklas@
2005-01-04restrict forwarding to ipsec processed traffic of ip.forwarding==2Markus Friedl
ok deraadt, henning, fgsch, mcbride
2005-01-04Move processing of ARP packets for CARP addresses to the carp interfaceChristopher Pascoe
instead of processing them in the parent interface. This causes us to send ARP packets on a carpdev with its virtual MAC address as the source, rather than the parent's physical address. Permits us to fail over cleanly when connected to devices that use the source MAC address on a received ARP request to generate an ARP entry for the requesting host, rather than going through the who-has/is-at procedure. ok niklas@ mcbride@
2005-01-04Use pseudo_AF_HDRCMPLT for outgoing ARP messages, otherwise the providedChristopher Pascoe
source MAC address we provide is ignored by ether_output. ok mcbride@ niklas@

2004-12-29fix indentMarkus Friedl
2004-12-22Instead of running carp_setroute synchronously, use if_addrhooks to get aChristopher Pascoe
callback after in_ifinit has run. This lets us correct any routes that in_ifinit has incorrectly added for our interface. Also be more explicit with the routing checks/changes that we make. This makes it possible to have different prefix lengths on a CARP interface and the physical interface it is bound to. ok mcbride@
2004-12-19#define sc_if sc_ac.ac_if, makes things a little more readable, andRyan Thomas McBride
kills a couple of ugly line wraps. From Max Laier. ok pascoe@

ok pascoe@ mpf@
2004-12-18Decrement carp_suppress_preempt when detaching an interface that hasChristopher Pascoe
been experiencing output errors. ok mcbride@
2004-12-17Temporary fix to get IPv6 working again.Marco Pfatschbacher
v6 advertisements are still received the old-fashioned way. ok mcbride@
2004-12-17Reorder code in the ethernet output path, and enhance unicast addressChristopher Pascoe
matching in the bridge receive path to make CARP operate correctly on physical interfaces that are participating in a bridge. ok mcbride@ henning@ dlg@
2004-12-17Remember to decrement carp_suppress_preempt when detaching.Ryan Thomas McBride
ok pascoe@
2004-12-15Add IFF_NOARP to carp interface, we want arp requests to be handled viaRyan Thomas McBride
carp_iamatch() on the physical interface. ok pascoe@ mpf@

2004-12-10Add carp_set_enaddr(), call carp_set_state() after changing the vhidRyan Thomas McBride
to trigger a gratuitous arp and update arp tables on other hosts.

2004-12-08Remove code duplication duplication. Use carpdetach() in carp_clone_destroy().Ryan Thomas McBride
2004-12-08Merge in more fixes from a pre-carpdev diff from Chris Pascoe.Ryan Thomas McBride
2004-12-08Check if_type in carp_carpdev_state() to make sure we're notRyan Thomas McBride
dealing with a carp interface.
2004-12-07Convert carp(4) to behave more like a regular interface, much in the sameRyan Thomas McBride
style as vlan(4). carp interfaces no longer require the physical interface to be on the same subnet as the carp interface, or even that the physical interface has an adress at all, so CARP can now be used on /30 networks. ok deraadt@ henning@
2004-12-06also consider NFS_PORT to be a reserved port, as in 1.18 or something likeTheo de Raadt
that.
2004-12-06ipsec udpencap check was done after baddynamicports ports checks (thoseTheo de Raadt
tables only map from 512 to 1023 using bitmaps, sorry); ok hshoexer

2004-11-25fix for race between invocation for timer and network inputMarkus Friedl
1) add a reaper for TCP and SYN cache states (cf. netbsd pr 20390) 2) additional check for TCP_TIMER_ISARMED(TCPT_REXMT) in tcp_timer_persist() with mickey@; ok deraadt@
2004-11-24Multicast routing cleanup from Pavlin RadoslavovRyan Thomas McBride
- sync ip_mroute.c with NetBSD - import some FreeBSD changes to MFC entry handling - set im->im_vif correctly when sending IGMPMSG_WRONGVIF - increment mrtstat.mrts_upcalls correctly - return error from get_sg_cnt() if there is no matching forwarding entry ok henning@ brad@ naddy@
