Jiri Bohac 19b7f763b3 Install selectors on transport mode IPsec SAs. 
This fixes several test cases in IKEv2_Self_Test (part of the IPv6 Ready
Logo Program) which is required for USGv6 certification, namely:

  - IKEv2.EN.I.1.1.7.1, IKEv2.EN.I.1.1.7.1: Narrowing the range of members
    of the set of traffic selectors
  - IKEv2.EN.R.1.1.7.3: Narrowing multiple traffic selector

When traffic selectors of a triggered SA are narrowed by the responder, the
installed policy and the broader trap policy share the same reqid.  Without
selectors on the IPsec SA packets matching the trap policy, but not the
narrowed policy, would incorrectly be handled by that IPsec SA.  Since only
one selector can be specified per IPsec SA, there is currently no solution
for tunnel mode SAs.

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 e66420566c Do not checkin a previously destroyed SA 2010-11-16 10:25:33 +01:00
Thomas Egerer 8f927116be Extend connected peers by peer family 
This allows for simultanious IPv4 and IPv6 tunnel for same peers with
matching identities.

Tobias Brunner 1dbf0ed982 Do not add additional addresses to MOBIKE path probing messages. 2010-10-12 11:11:06 +02:00
Tobias Brunner 5774408898 Change behavior of responder during roaming. 
If the current source address is not available anymore, the responder
uses ike_mobike_t.roam, thus, uses multiple address combinations when
trying to notify the initiator.
 2010-10-12 11:11:05 +02:00
Tobias Brunner c5770f864f Allow responder to use ike_mobike_t.roam. 
After getting a response the responder updates the IPsec SAs.
 2010-10-12 11:11:05 +02:00
Tobias Brunner 261b2572d1 Send list of additional addresses even if current path is still valid. 2010-10-12 11:11:05 +02:00
Tobias Brunner bab56a4abb Extracted path checking in ike_sa_t.roam into separate functions. 2010-10-12 11:11:05 +02:00
Tobias Brunner 769c69facc Added support for responders to change their address via MOBIKE. 
If the original responder updates its list of additional addresses we
check if the remote endpoint changed and update the IPsec SAs if it did,
as we assume the original address became unavailable and the responder
already updated the SAs on its side.
 2010-10-12 11:11:05 +02:00
Tobias Brunner 13876431d6 Explicitly configure MOBIKE tasks to update the list of additional addresses. 2010-10-12 11:11:05 +02:00
Tobias Brunner 31e7dc4dfd Improved check for first IKE_AUTH message in ike_mobike task. 
If the original responder initiated a MOBIKE exchange, the previous
check was not always correct.

Tobias Brunner c817e7bb90 Migrated ike_mobike task to INIT/METHOD macros. 2010-10-12 11:11:05 +02:00
Tobias Brunner be90134211 Simplified apply_port function in mobike task. 2010-10-12 11:11:04 +02:00
Tobias Brunner cd26eedc5c Do not update hosts based on retransmitted messages. 2010-10-12 11:11:04 +02:00
Tobias Brunner d5bd775126 Do not update remote host if we are behind a NAT. 2010-10-12 11:11:04 +02:00
Andreas Steffen 3c354b6d11 NOTIFY error message types include 16383 2010-09-29 19:01:36 +02:00
Tobias Brunner 71b6d2ff5e Adapted child_sa_t to changed kernel interface. 2010-09-02 19:04:22 +02:00
Tobias Brunner bd7a2f3bfc Added an option to specify the type of a policy to kernel_ipsec.add_policy. 
This will later allow us to support pluto's passthrough and drop
policies in charon.
 2010-09-02 19:04:19 +02:00
Tobias Brunner b4872c1e09 Replaced the protocol argument in add_policy with an optional SPI for an AH SA. 2010-09-02 19:04:19 +02:00
Tobias Brunner bb381e26c6 Refer to scheduler and processor via lib and not hydra. 2010-09-02 19:04:18 +02:00
Tobias Brunner f6659688ab Refer to kernel interface via hydra and not charon. 2010-09-02 19:01:25 +02:00
Tobias Brunner 9f166d9ac2 Removed references to protocol_id_t from kernel interface. 
Instead we use the actual IP protocol identifier (the conversion now happens in
child_sa_t and kernel_handler_t).
 2010-09-02 19:01:25 +02:00
Tobias Brunner 9d94174242 Migrated child_sa_t to INIT/METHOD macros. 2010-09-02 19:01:25 +02:00
Tobias Brunner 61e8e73206 Refer to scheduler via hydra and not charon. 2010-09-02 19:01:24 +02:00
Tobias Brunner c5f7146b17 Refer to processor via hydra and not charon. 2010-09-02 19:01:22 +02:00
Martin Willi 36eafea232 Use the AAA Identity for EAP authentication, if given 2010-08-31 18:10:23 +02:00
Martin Willi f13a03add0 Moved EAP type/code definitions to a seprate header file in libstrongswan 2010-08-31 15:35:29 +02:00
Tobias Brunner 2402dee177 Port floating patch partially reversed. 
If MOBIKE is enabled, we do have to switch to port 4500 with the
IKE_AUTH request, that is, before we know whether the other peer
actually supports MOBIKE or not.
 2010-08-30 14:54:31 +02:00
Tobias Brunner 277f02ce9e Slightly refactored port floating. 
In case of MOBIKE, only float to port 4500 if the other peer actually supports MOBIKE.

Tobias Brunner fde2d34d0f Fixed ME after introduction of AEAD wrapper. 2010-08-30 10:48:09 +02:00
Martin Willi 5299719569 Migrated delete_payload to INIT/METHOD macros, replaced iterator 2010-08-25 17:03:00 +02:00
Thomas Egerer e54e86cb49 Check if colliding rekey actually created an IKE_INIT 
In some cases (especially if a child is half-open) the colliding
rekey-job might not have created the ike_init member. If so, the
nonce check fails with SIGSEGV.
