Tobias Brunner 9e3ab0d114 ikev2: Reorder task activation for established IKE SAs 
We now prefer MOBIKE tasks over delete tasks then the rest.

Tobias Brunner b3a7ba14f1 Revert "ikev2: Insert MOBIKE tasks at the front of the queue" 
This reverts commit 3293d14628.

The position of tasks in the queue does not actually determine the order
in which they are activated.  Instead this is determined by the
statements in task_manager_v2_t.initiate().

Martin Willi a336aefa89 curl: For SSL features, depend on thread-safety provided by our crypto plugins 
To use SSL in curl, we need to initialize the SSL library in a thread-safe
manner and provide the appropriate callbacks. As we already do that in our
crypto plugins using these libraries, we depend on these features.

This implies that we need the same plugin enabled (openssl, gcrypt) as the
curl backend is configured to use to fetch from HTTPS URIs.

Martin Willi 6eaec1e349 leak-detective: Whitelist libssl SSL_COMP_get_compression_methods() 
This function is called by libcurl initialization with SSL, and uses
a static allocation of compression algorithms not freed.
 2014-09-24 11:35:59 +02:00
Martin Willi 85c95db17a curl: Try to initialize with SSL support to handle https:// URIs 
If initialization fails, we fall back to the old behavior.

Martin Willi 5ea627bdfa watcher: Add a method to query the watcher state 
This allows a user to check if the watcher is actually running, and potentially
perform read operations directly instead of relying on watcher.

Martin Willi 12c0bde689 kernel-netlink: Define and use rtnetlink message types 2014-09-24 11:19:59 +02:00
Martin Willi c94e93a7ab kernel-netlink: Pass protocol specific enum names to socket constructor 
This avoid the hard dependency on enum names, and makes kernel_netlink_shared
independent of kernel_netlink_ipsec.

Martin Willi 5957e76b38 kernel-netlink: Clean up socket initialization, handle 0 as valid socket fd 2014-09-24 11:19:59 +02:00

Martin Willi de11d34abb kernel-netlink: Use recv() instead of recvfrom() 
As we are not interested in the returned address, there is really no need
in passing that argument.

Martin Willi 4c438cf099 kernel-netlink: Avoid casting the NLMSG_DATA() return value 
There is really no need for doing so, and it makes the code just unreadable.
 2014-09-24 11:19:59 +02:00
Martin Willi 0404a29bfe kernel-netlink: Define netlink buffer as an union having a netlink header 
This allows us to streamline the netlink buffers, and avoid extensive
casting.

Martin Willi d8ad0fc351 settings: Make loading a NULL or empty pattern a (nop-)success 2014-09-22 13:40:39 +02:00
Martin Willi 68da3bad57 settings: Use strongswan.conf used during library initialization for reload 
Since 4b670a20 we require an explicit strongswan.conf to re-load configurations.
However, the define was missing in the build, breaking SIGHUP based config
reloading.

Fixes #651.

Tobias Brunner 22949c590f ikev2: Don't treat initial messages as MOBIKE exchanges 
The MOBIKE task is active during the initial exchanges but we don't want
to treat them as actual MOBIKE exchanges (i.e. there is no path probing).

Tobias Brunner 8a6b01dd2a ikev1: Don't cache last block of INFORMATIONAL messages as IV 
We don't expect a response with the same MID, but apparently some
devices (e.g. FRITZ!Box) do that for DPDs, while still treating the
response as a new exchange.  By storing the last message block as IV
we can't decrypt the first block of such a response.

Fixes #661.

Tobias Brunner 84337ac8d0 ikev1: Properly handle different proposal numbering schemes 
While the examples in RFC 2408 show proposal numbers starting at 1 and
increasing by one for each subsequent proposal this is not mandatory.
Actually, IKEv1 proposals may start at any number, the only requirement
is that the proposal numbers increase monotonically they don't have to
do so consecutively.

Most implementations follow the examples and start numbering at 1 (charon,
racoon, Shrew, Cisco, Windows XP, FRITZ!Box) but pluto was one of the
implementations that started with 0 and there might be others out there.

The previous assumption that implementations always start numbering proposals
at 0 caused problems with clients that start numbering with 1 and whose first
proposal consists of multiple protocols (e.g. ESP+IPComp).

Fixes #661.

Tobias Brunner 8956dcecd4 ike-mobike: Allow calling transmit() even when not currently path probing 
Path probing is enabled if the current path is not available anymore.
 2014-09-12 10:29:37 +02:00
Tobias Brunner 10bad0fc23 ikev2: Defer path probing if no path is currently available 
We do the same before initiating the task, so we should probably do it
too when we already initiated it, not just time out and destroy the SA.

Tobias Brunner 7840952edc ike-mobike: Return FALSE in transmit() if no path was available 2014-09-12 10:29:36 +02:00
Tobias Brunner 1b17f647a5 ikev2: Enable path probing for currently active MOBIKE task 
This might not be the case if e.g. an address appeared but the old one
is still available but not actually usable.  Without this the MOBIKE
task would eventually time out even though we might be able to switch
to a working address.

Tobias Brunner 3293d14628 ikev2: Insert MOBIKE tasks at the front of the queue 
In case we have no usable path to the other peer there is no point in
initiating any other tasks (like rekeying).

Tobias Brunner 40164bbe27 ikev2: Migrate number of pending MOBIKE updates 
This will probably never be more than 1 since we only have one task queued
at a time and we don't migrate running tasks.
 2014-09-12 10:29:36 +02:00
Tobias Brunner 03f61ba3d5 ikev2: Properly keep track of pending MOBIKE updates 
Because we only queue one MOBIKE task at a time, but destroy superfluous
ones only after we already increased the counter for pending MOBIKE updates,
we have to reduce the counter when such tasks are destroyed.  Otherwise, the
queued task would assume another task is queued when it is running and
ignore any successful response.

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.
