Tobias Brunner b1ef481ce1 proposal: Add default PRF for HMAC-MD5-128 and HMAC-SHA1-160 integrity algorithms 2014-10-31 10:09:54 +01:00

Tobias Brunner f92399ef18 child-cfg: Ignore duplicate proposals 
If ESP proposals are added once with and once without DH groups
duplicates result during IKE_AUTH when DH groups are stripped.

Martin Willi 2f893f278d proposal: Don't return a default IKE proposal without encryption/AEAD algs 2014-05-16 16:51:19 +02:00
Martin Willi 356846db5d child-cfg: Allow passing NULL as proposal to add_proposal() 
Making the API consistent to the one of ike_cfg.

Martin Willi 3312c447ef ike-cfg: Allow passing NULL to add_proposal() 
This simplifies adding default proposals with constructors potentially
returning NULL.

Martin Willi 8642f8bdb7 proposal: Use an additional "default" constructor specific to AEAD algorithms 
This allows a caller to create a separated proposal for supported AEAD
algorithms, as required by RFC 5996.
 2014-05-16 16:01:21 +02:00
Martin Willi 0fc4dd429d proposal: Don't include AEAD algorithms in the default proposal 
According to RFC 5996 3.3 we should use a separate proposal for AEAD algorithms.
This was not clear in RFC 5282, hence we previously included both AEAD and
non-AEAD algorithms in a single proposal.

Tobias Brunner c478dfe617 child-cfg: Fix removal of redundant traffic selectors 
We have to make sure we compare every selected traffic selector with every
other in the list.

Fixes #577.

Tobias Brunner 23f34f6ed5 ike-cfg: Properly compare IKE proposals for equality 2014-04-03 09:46:41 +02:00
Tobias Brunner a213944d4a proposal: Don't fail DH proposal matching if peer includes NONE 
The DH transform is optional for ESP/AH proposals. The initiator can
include NONE (0) in its proposal to indicate that while it prefers to
do a DH exchange, the responder may still decide to not do so.

Fixes #532.

Martin Willi f0c59e1cf8 proposal: Strip redundant integrity algos for ESP proposals only 2013-10-11 10:15:21 +02:00
Martin Willi 3070697f9f ike: support multiple addresses, ranges and subnets in IKE address config 
Replace the allowany semantic by a more powerful subnet and IP range matching.
Multiple addresses, DNS names, subnets and ranges can be specified in a comma
separated list. Initiators ignore the ranges/subnets, responders match
configurations against all addresses, ranges and subnets.

Martin Willi 2fa92ad256 proposal: correctly enumerate registered AEADs to build default IKE proposal 
AEADs are not returned (anymore) with the encryption enumerator.

Tobias Brunner 0ceb288815 Fix various API doc issues and typos 
Partially based on an old patch by Adrian-Ken Rueegsegger.

Martin Willi c907b57f56 proposal: use array to store proposal list 
Removes another two linked lists (0.5KB) of memory per IKE/CHILD_SA pair.
 2013-07-17 17:20:18 +02:00
Martin Willi 5cd64f979c proposal: use a single list to store all transforms 
Beside that it makes the code actually simpler, it reduces the number of lists
stored by each IKE_SA and each CHILD_SA by 4, which can be up to 1KB per SA.

Martin Willi a485320393 Raise an alert if the responding peer narrowed traffic selectors 2013-06-19 16:11:46 +02:00
Martin Willi 246e2bed1d Use subset matching instead of is_contained_in() to select a child_cfg 
If one selector has a wider IP range than the other, but the other has a
wider port/protocol selector than the first one, none is completely contained
in the other. The check for a match using is_contained_in() therefore would
fail. Using get_subset() can handle such cases, fixing configuration selection.

Tobias Brunner f4cc7ea11b Add uniqueids=never to ignore INITIAL_CONTACT notifies 
With uniqueids=no the daemon still deletes any existing IKE_SA with the
same peer if an INITIAL_CONTACT notify is received.  With this new option
it also ignores these notifies.
