2005-03-01Unbreak arp_input with carp; add back the call to carp_iamatch()Ryan Thomas McBride
which was removed in rev 1.57. This makes arpbalance work again, and ensures that only one carp host will reply to a given arp request. ok mpf@ pascoe@ dhartmei@ deraadt@
2005-02-28Remove unused variable if_flags in struct carp_softc, ok mickey@Ryan Thomas McBride
2005-02-271. tcp_xmit_timer(): remove extra rtt decrement (t_rtttime is 0-basedMarkus Friedl
while t_rtt was 1-based), update callers 2. define and use TCP_RTT_BASE_SHIFT instead of the hardcoded 2. 3. add missing shifts when t_srtt/t_rttvar are used. 4. update the comments: t_srtt uses 5 bits of fraction (not 3) and t_rttvar uses 4 bits 5. remove obsolete/unused macros TCP_RTT_SCALE and TCP_RTTVAR_SCALE 6. make sure rttmin is not > TCPTV_REXMTMAX parts from netbsd, ok mcbride, henning

with an id10t error by yours truly.
2005-02-07Prevent carp from attaching to other carp interfaces, which theRyan Thomas McBride
ifp->if_flags & IFF_MULTICAST checks no longer protect against. ok pascoe@ mpf@
2005-02-07There is no SIOCDIFADDR call into interfaces on address deletion, soChristopher Pascoe
use our carp_addr_updated callback to detect deletion and reconfigure appropriately. ok mcbride@

2005-01-18Rewriting the lladdr can now be done without using mbuf tags.Marco Pfatschbacher
Advertisements run through the carp interface first. So we just take the address from ifp0. While we're there, also remove carp_macmatch6, which isn't used anymore. Proposed by mcbride@ ok mcbride@, pascoe@
2005-01-18Use correct source address for ICMP errors generated from packets that wereClaudio Jeker
not addressed to the machine. If the destination is not a local address do a route lookup for the original source address and use the returned interface address. This solves problems seen on interfaces with multiple networks defined. OK henning@ markus@
2005-01-15From NetBSD:Christopher Pascoe
- Keep track of allhost multicast address record we joined into each in_ifaddr and delete it when an address is purged. - Don't simply try to delete a multicast address record listed in the ia_multiaddrs. It results a dangling pointer. Let whoever holds a reference to it to delete it. mcbride@ markus@ ok

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@

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@

2004-12-08Check 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.
