Martin Willi e15f64cc81 tls: Support a maximum TLS version to negotiate using TLS socket abstraction 2014-04-01 14:28:55 +02:00
Martin Willi 5313880261 tls: Support a null encryption flag on TLS socket abstraction 2014-04-01 14:28:55 +02:00
Martin Willi e5d73b0dfa aead: Support custom AEAD salt sizes 
The salt, or often called implicit nonce, varies between AEAD algorithms and
their use in protocols. For IKE and ESP, GCM uses 4 bytes, while CCM uses
3 bytes. With TLS, however, AEAD mode uses 4 bytes for both GCM and CCM.

Our GCM backends currently support 4 bytes and CCM 3 bytes only. This is fine
until we go for CCM mode support in TLS, which requires 4 byte nonces.

Martin Willi e12eec1008 ikev2: Recreate a CHILD_SA that got a hard lifetime expire without rekeying 
Works around issues related to system time changes and kernel backends using
that system time, such as Linux XFRM.

Tobias Brunner 3b09c02ec0 Properly hash pointers for hash tables where appropriate 
Simply using the pointer is not optimal for our hash table
implementation, which simply masks the key to determine the bucket.

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 961409b668 lookip: Disconnect asynchronously to avoid dead-locking watcher unregistration 
While it really would be desirable to allow stream destruction during on_read()
callbacks, this does not work anymore since e49b2998. Until we have a proper
solution for this issue, use asynchronous disconnects for the only user doing
so.

Fixes #518.

Tobias Brunner 6e288ed19c pool: Install SQL schemas from src/pool 
This allows us to install the schemas if either the attr-sql or sql
plugin is enabled, since both use the same schema (at least in parts).

Tobias Brunner 9e1ce63915 ikev1: Fix config switching due to failed authentication during Aggressive mode 
The encoded ID payload gets destroyed by the authenticator, which caused
a segmentation fault after the switch.

Fixes #501.

Martin Willi ac2dc3b726 updown: Return an empty DNS server enumerator if no IKE_SA available 
The one existing caller does not handle a NULL return and always expects
an enumerator; and returning FALSE does not make sense anyway.

Martin Willi d048a319df ike: Restart inactivity counter after doing a CHILD_SA rekey 
When doing a rekey for a CHILD_SA, the use counters get reset. An inactivity
job is queued for a time unrelated to the rekey time, so it might happen
that the inactivity job gets executed just after rekeying. If this happens,
inactivity is detected even if we had traffic on the rekeyed CHILD_SA just
before rekeying.

This change implies that inactivity checks can't handle inactivity timeouts
for rekeyed CHILD_SAs, and therefore requires that inactivity timeout is shorter
than the rekey time to have any effect.

This avoids passing that arbitrary label just for error messages, and gives
greater flexibility in handling errors.

Tobias Brunner 21c18f536d unity: Send all traffic selectors in a single UNITY_SPLIT_INCLUDE attribute 
Cisco clients only handle the first such attribute.

Tobias Brunner f8262aa1a6 unity: Change local TS to 0.0.0.0/0 as responder 
Cisco clients and Shrew expect a remote TS of 0.0.0.0/0 if Unity is
used, otherwise Quick Mode fails.
 2014-01-23 10:35:21 +01:00
Tobias Brunner 685579d6d8 unity: Send UNITY_SPLIT_INCLUDE attributes with proper padding 
The additional 6 bytes are not actually padding but are parsed by the
Cisco client as protocol and src and dst ports (each two bytes but
strangely only the first two in network order).
