Martin Willi f6f16131d0 Raise a bus alert when a received message contains unknown SPIs 2012-10-24 11:34:30 +02:00
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.

Martin Willi 10bdc7a968 Remove the unused second IKE_SA entry match function argument
LLVMs clang complains about this parameter, so remove it.

Tobias Brunner 6204c1182d Include src address in hash of initial message for Main Mode
If two initiators use the same SPI and also use the same SA proposal the
hash for the initial message would be exactly the same.  For IKEv2 and
Aggressive Mode that's not a problem as these messages include random
data (Ni, KEi payloads).

Martin Willi 4837d2a981 Fix iteration through half-open IKE_SA table 2012-04-16 16:47:17 +02:00
Tobias Brunner d112a7e1fe Properly handle retransmitted initial IKE messages.
This change allows to properly handle retransmits of initial IKE
messages when we've already processed them (i.e. our response is now resent
immediately).

Tobias Brunner 4b2f428f40 Do not clone hashes of initial IKE messages when storing them in the hash table. 2012-03-20 17:31:40 +01:00
Tobias Brunner 20e3d5ea00 Store IKEv2 IKE_SAs by local SPI in the IKE_SA manager hash table.
For IKEv1 the previous behavior of always using the initiator's SPI as
key is maintained.
2012-03-20 17:31:40 +01:00
Tobias Brunner 71cf97871f Added separate hashtable for hashes of initial IKE messages.
This does not require us to do a lookup for an SA by SPI first.

Tobias Brunner 4bbce1ef37 Replaced ike_sa_t.create_child_sa_iterator with enumerator.
This required two new methods on ike_sa_t. One returns the number of
CHILD_SAs and one allows to remove a CHILD_SA.

Martin Willi 86993d6b90 Never register IKE_SA during checkout_new, as rekeying keeps it checked out 2010-12-07 16:30:38 +01:00
Thomas Egerer 76ce213c43 Guarantee entry->other is set when calling put_connected_peers
Given the original intent of entry->host, the check for DoS attacks, it
can happen that this value remains NULL when an entry is created. This
is particularly awkward if put_connected_peers is called to check if a
connection to a given peer already exists, since it takes the address
family into consideration (git commit b74219d0) which is gleaned from
entry->host.
This patch guarantees that entry->other is a clone of host before
put_connected_peers is called.

Thomas Egerer 8f927116be Extend connected peers by peer family
This allows for simultanious IPv4 and IPv6 tunnel for same peers with
matching identities.
