* Move #ifdef INET6 outside of 'case AF_INET6:' in tcp_ident().mcbride2005-02-221-2/+2
| | | | | | | No functional change due to earlier check, fix from Maxim Konovalov <maxim@macomnet.ru> ok deraadt@ dhartmei@
* miscellaneous typo fixes:jfb2005-02-171-2/+2
| | | | | | | - sturct -> struct (spotted by pedro) - elimination of consecutive 'the' words ok jmc@, henning@, krw@, robert@, some whining by jolan@

* Prevent carp from attaching to other carp interfaces, which themcbride2005-02-071-35/+25

* There is no SIOCDIFADDR call into interfaces on address deletion, sopascoe2005-02-071-20/+35
| | | | | | | use our carp_addr_updated callback to detect deletion and reconfigure appropriately. ok mcbride@

* Rewriting the lladdr can now be done without using mbuf tags.mpf2005-01-182-145/+5
| | | | | | | | | | 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@
* Use correct source address for ICMP errors generated from packets that wereclaudio2005-01-181-11/+7
| | | | | | | 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@
* From NetBSD:pascoe2005-01-152-7/+10
| | | | | | | | | | - 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

* Make sure bogus values don't make their way into tcp_xmit_timer() calculations.mcbride2005-01-103-10/+21
| | | | | | | | | | - 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@

* Attach multicast to the carp interface for IPv6 (makes it consistent withmcbride2005-01-061-29/+17

* Tag all packets sent via a CARP interface for link local addresspascoe2005-01-061-3/+21

* Move processing of ARP packets for CARP addresses to the carp interfacepascoe2005-01-042-11/+8
| | | | | | | | | | | | 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@

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@
