* android: New release based on 5.1.3Tobias Brunner2014-04-252-3/+3
| | | | | Also links OpenSSL statically and doesn't limit the number of packets during EAP-TTLS.
* libcharon: Added AEAD sources of libtls to Android.mkTobias Brunner2014-04-251-0/+1
|
* libimcv: Updated Android.mkTobias Brunner2014-04-251-0/+3
|
* android: Use static version of libcryptoTobias Brunner2014-04-252-2/+1
| | | | | System.loadLibrary() searches in system directories first (at least in recent releases), that is, our own build wouldn't actually get used.
* tun-device: Use SIOCAIFADDR to set IP address on FreeBSD 10Tobias Brunner2014-04-251-2/+90
| | | | | | | | FreeBSD 10 deprecated the SIOCSIFADDR etc. commands, so we use this newer command to set the address and netmask. A destination address is now also required. Fixes #566.
* Merge branch 'atomic-ref'Tobias Brunner2014-04-247-29/+134
|\ | | | | | | | | | | | | | | Adds support for GCC's __atomic* built-ins and improves the performance of logging (for ignored log levels) and half-open IKE_SA checking under high loads. Also fixes two potential race conditions in the load-tester plugin.
| * bus: Add a fast-path if log messages don't have to be loggedTobias Brunner2014-04-241-7/+53
| | | | | | | | | | | | | | For some rwlock_t implementations acquiring the read lock could be quite expensive even if there are no writers (e.g. because the implementation requires acquiring a mutex to check for writers) particularly if the lock is highly contended, like it is for the vlog() method.
| * load-tester: Fix race condition issuing same SPIChristophe Gouault2014-04-241-2/+2
| | | | | | | | | | | | | | | | | | | | Due to an unprotected incrementation, two load-tester initiators occasionally use the same SPI under high load, and hence generate 2 IPsec SAs with the same identifier. The responder IPsec stack will refuse to configure the second SA. Use an atomic incrementation to avoid this race condition. Signed-off-by: Christophe Gouault <christophe.gouault@6wind.com>
| * load-tester: Fix race condition issuing same identityChristophe Gouault2014-04-241-2/+2
| | | | | | | | | | | | | | | | | | | | Due to an unprotected incrementation, two load-tester initiators occasionally use the same identifier under high load. The responder typically drops one of the connections. Use an atomic incrementation to avoid this race condition. Signed-off-by: Christophe Gouault <christophe.gouault@6wind.com>
| * ike-sa-manager: Improve scalability of half-open IKE_SA checkingTobias Brunner2014-04-241-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on one by Christoph Gouault. Currently, to count the total number of half_open IKE_SAs, get_half_open_count sums up the count of each segment in the SA hash table (acquiring a lock for each segment). This procedure does not scale well when the number of segments increases, as the method is called for each new negotiation. Instead, lets maintain a global atomic counter. This optimization allows the use of big values for charon.ikesa_table_size and charon.ikesa_table_segments.
| * utils: Use GCC's __atomic built-ins if availableTobias Brunner2014-04-243-8/+45
| | | | | | | | | | | | | | | | These are available since GCC 4.7 and will eventually replace the __sync operations. They support the memory model defined by C++11. For instance, by using __ATOMIC_RELAXED for some operations on the reference counters we can avoid memory barriers, which are required by __sync operations (whose memory model essentially is __ATOMIC_SEQ_CST).
| * utils: Add ref_cur() to retrieve the current value of a reference counterTobias Brunner2014-04-242-3/+24
|/ | | | | | | | | | On many architectures it is safe to read the value directly (those using cache coherency protocols, and with atomic loads for 32-bit values) but it is not if that's not the case or if we ever decide to make refcount_t 64-bit (load not atomic on x86). So make sure the operation is actually atomic and that users do not have to care about the size of refcount_t.
* testing: Added pfkey/compress test caseTobias Brunner2014-04-249-0/+100
|
* kernel-pfkey: Added IPComp supportFrancois ten Krooden2014-04-241-19/+138
| | | | | | - get_cpi function was implemented to retrieve a CPI from the kernel. - add_sa/update_sa/del_sa were updated to accommodate for IPComp SA. - Updated add_policy_internal to update the SPD to support IPComp.

* Merge branch 'reauth-collision'Martin Willi2014-04-172-2/+53
|\ | | | | | | Fixes two collisions between IKE_SA re-authentication and CHILD_SA rekeying.
| * ike: Delay actively initiated reauthentication when other exchanges in progressMartin Willi2014-04-171-2/+47
| | | | | | | | | | If any other IKE or CHILD_SA operation takes places, we should not start initiating reauthentication to avoid any potential races.
| * ikev2: Reject CHILD_SA creation/rekeying while deleting an IKE_SAMartin Willi2014-04-171-0/+6
|/ | | | | | | | | | | If one peer starts reauthentication by deleting the IKE_SA, while the other starts CHILD_SA rekeying, we run in a race condition. To avoid it, temporarily reject the rekey attempt while we are in the IKE_SA deleting state. RFC 4306/5996 is not exactly clear about this collision, but it should be safe to reject CHILD_SA rekeying during this stage, as the reauth will re-trigger the CHILD_SA. For non-rekeying CHILD_SA creations, it's up to the peer to retry establishing the CHILD_SA on the reauthenticated IKE_SA.
* ikev2: Apply extensions and conditions before starting rekeyingMartin Willi2014-04-171-0/+6
| | | | | | The extensions and conditions apply to the rekeyed IKE_SA as well, so we should migrate them. Especially when using algorithms from private space, we need EXT_STRONGSWAN to properly select these algorithms during IKE rekeying.
* ikev2: Add inherit_pre() to apply config and hosts before IKE_SA rekeyingMartin Willi2014-04-174-22/+30
|
* ikev1: Add an option to accept unencrypted ID/HASH payloadsMartin Willi2014-04-172-1/+35
| | | | | | | | | Even in Main Mode, some Sonicwall boxes seem to send ID/HASH payloads in unencrypted form, probably to allow PSK lookup based on the ID payloads. We by default reject that, but accept it if the charon.accept_unencrypted_mainmode_messages option is set in strongswan.conf. Initial patch courtesy of Paul Stewart.
* ikev2: Fix reauthentication if peer assigns a different virtual IPTobias Brunner2014-04-151-1/+1
| | | | | | | | | | | | | | | | | Before this change a reqid set on the create_child_t task was used as indicator of the CHILD_SA being rekeyed. Only if that was not the case would the local traffic selector be changed to 0.0.0.0/0|::/0 (as we don't know which virtual IP the gateway will eventually assign). On the other hand, in case of a rekeying the VIP is expected to remain the same, so the local TS would simply equal the VIP. Since c949a4d5016e33c5 reauthenticated CHILD_SAs also have the reqid set. Which meant that the local TS would contain the previously assigned VIP, basically rendering the gateway unable to assign a different VIP to the client as the resulting TS would not match the client's proposal anymore. Fixes #553.

* attr: Don't shift the 32-bit netmask by 32Tobias Brunner2014-04-091-3/+6
| | | | | | | | | | This is undefined behavior as per the C99 standard (sentence 1185): "If the value of the right operand is negative or is greater or equal to the width of the promoted left operand, the behavior is undefined." Apparently shifts may be done modulo the width on some platforms so a shift by 32 would not shift at all.
