2014-01-23Remove a mid-layer which acts like arc4random isn't fairly standard.Theo de Raadt
ok mikeb
2014-01-22improve randomization. remove some junk debugging features that areTheo de Raadt
fundamentally broken. ok jsing mikeb
2013-11-21Keep the flow until last IPsec SA is deleted, if the flow is shared byYASUOKA Masahiko
multiple IPsec SAs in NAT-T case. This fixes a problem that L2TP/IPsec connections are disconnected improper in case multiple Windows clients are connected from behind one NAT. ok markus

2012-01-16import (and fix) net_addrcmp() from libc as a static function.Eric Faurot
It is going to get removed from libc and this file is the only one using it. discussed with deraadt@ guenther@ ok deraadt@
2010-12-09When looking up an SA based on peer address, also check the portMartin Hedenfal
number. Without this, isakmpd deletes SAs from the same IP on an INITIAL-CONTACT message, possibly deleting unrelated NATed tunnels. Fixes PR 5562. Verified by Mikolaj Kucharski. ok mikeb@
2010-09-22Support for use of AES-GCM-16 (as AESGCM) and ENCR_NULL_AUTH_AES_GMACMike Belopuhov
(as AESGMAC) ciphers in the ISAKMP Phase 2 (aka Quick Mode). Thoroughly tested by me and naddy. Works fine with Linux. Requires updated pfkeyv2.h include file. ok naddy

2007-04-16There's no point in checking ptr for NULL before doing free(ptr)Moritz Jodeit
since free(NULL) is just fine. ok hshoexer@
2006-11-24add support to tag ipsec traffic belonging to specific IKE-initiatedReyk Floeter
phase 2 traffic. this allows policy-based filtering of encrypted and unencrypted ipsec traffic with pf(4). see ipsec.conf(5) and isakmpd.conf(5) for details and examples. this is work in progress and still needs some testing and feedback, but it is safe to put it in now. ok hshoexer@
2006-08-30Back out r1.103, which caused SA's to leak until memory was exhausted.Chad Loder

2006-05-31Make sure, that phase 1 SAs of active connections stay alive. Fixes a DPDHans-Joerg Hoexer
breakage noticed and reported by Mitja Muzenic. ok markus@ ho@, testing by Mitja and cloder@, discussed with Nathanael.
2006-05-29Do not use C++ comments. Noticed by markus.Hans-Joerg Hoexer
2006-05-29Oops, return after calling sa_release()Ryan Thomas McBride
2006-05-28Assign a finalization event to the exchange initiated on soft expiry.Ryan Thomas McBride
If the exchange fails, the existing phase 1 SA is invalidated and the exchange is retried at the Exchange-Max-Time interval until the SA hard timeout expires. Another sasyncd-related fix from nathanael at polymorpheous dot com ok ho@ hshoexer@
2006-05-28also report SA flags.Hans-Joerg Hoexer

2005-04-08Make deterministic randomness (only ever used for testing) a compile-timeChad Loder
option. Reduces chances of somehow setting regrand when it's not supposed to be set. Remove "-r" option from man page. Also xref certpatch(8) while we are in there. And remove some include sysdep.h where it is no longer needed. OK hshoexer

2004-05-13Extensions to the FIFO interface:Hakan Olsson
"C get [section]:tag" fetches a configuration value. "C add [section]:tag=value" adds 'value' to a list, typically for the [Phase 2]:Connections tag. FIFO "S" command destination file changed. Various KNF cleanups. hshoexer@ ok.
2004-04-15partial move to KNF. More to come. This has happened because thereTheo de Raadt
are a raft of source code auditors who are willing to help improve this code only if this is done, and hey, isakmpd does need our standard auditing process. ok ho hshoexer

2004-02-27(C)-2004Hakan Olsson
2004-02-27Follow RFC 2408 more closely regarding how to better check the proposalHakan Olsson
returned by the other peer (the responder). Some implementations (notably the Cisco PIX) does not follow a SHOULD in section 4.2 of the RFC. With certain proposal combinations this caused us to setup the wrong SA resulting in us being unable to process incoming IPsec traffic (over this tunnel). Tested against a number of different IKE implementations. hshoexer@ ok.
