Martin Willi 5c12700f9a kernel-interface: query SAD for last use time if SPD query didn't yield one 2013-05-06 17:01:13 +02:00
Martin Willi bdaf9f97e6 child-sa: query SAD/SPD just for what we actually need to update statistics 2013-05-06 17:01:13 +02:00
Martin Willi 60ed88b2c7 child-sa: pass traffic selector to add_sa() regardless of IPsec mode 
This lets the kernel backend decide what to do with it, and in fact all kernel
interfaces already handle this correctly.

Tobias Brunner c8f7a114b6 Mark CHILD_SAs used for trap policies to uninstall them properly. 
If the installation failed the state is not CHILD_ROUTED which means the
wrong priority is used to uninstall the policies.  This is a problem for
kernel interfaces that keep track of installed policies as now the proper
policy is not found (if the priority is considered).

Martin Willi 79f39ecf5d Added a getter for CHILD_SA marks 2012-03-22 09:06:12 +01:00

Tobias Brunner 241cf8e791 Update fallback drop policies if required. 2011-07-29 12:34:51 +02:00
Tobias Brunner f1c1965d64 Install fallback drop policies for all three directions. 2011-07-28 16:56:15 +02:00
Tobias Brunner d7a59f1976 Install fallback drop policies to avoid transmitting unencrypted packets. 
During the update of a CHILD_SA (e.g. caused by MOBIKE) the old policy
is first uninstalled and then the new one is installed.  In the short
time in between, where no policy is available in the kernel, unencrypted
packets could have been transmitted.

Tobias Brunner fbedc6a45b Remove policies in kernel interfaces based on their priority. 
This allows to unroute a connection while the same connection is
currently established.  In this case both CHILD_SAs share the same
reqid but the installed policies have different priorities.
 2011-07-27 13:41:35 +02:00
Tobias Brunner 328f22e1d3 Add the reqid to kernel_ipsec_t.del_policy. 2011-07-06 09:43:45 +02:00
Martin Willi bd01b9d8b2 Install ESN SAs if such a proposal has been negotiated 2011-04-20 12:26:58 +02:00

Martin Willi 37788b1d06 Added a TFC padding option to child_cfg 2010-12-20 09:45:39 +01:00

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.

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.

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 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).
