| * android: Increase the minSdkVersion to 15 and targetSdkVersion to 22Tobias Brunner2015-07-281-2/+2
|/ | | | | There are no devices anymore that use API level 14 (4.0-4.0.2) and 22 is the most recent level.
* testing: Regenerated BLISS certificates due to oracle changesAndreas Steffen2015-07-277-0/+0

* Use MGF1 with SHA-512 as BLISS random oracleAndreas Steffen2015-07-275-72/+63

* Generalize c_indices generation using SHA-512 random oracle.Markku-Juhani Olavi Saarinen2015-07-271-18/+24
| | | | | | This generalization allows the ring dimension n to be different from the current n = 512 and allows kappa to be > 56. Also the hash octets are consumed in a more consistent manner.
* Fixed several bugs in the BLISS signature generation/verification step.Markku-Juhani Olavi Saarinen2015-07-271-4/+8
| | | | | | | | | | | | | | | | The c_indices derived from the SHA-512 random oracle consist of nine bits (0..511). The leftmost 8 bits of each index are taken on an octet-by-octet basis from the 56 leftmost octets of the SHA-512 hash. The 9th bit needed for the LSB is taken from the extra_bits 64 bit unsigned integer which consists of the 8 rightmost octets of the SHA-512 hash (in network order). If more than 56 indices must be derived then additional rounds of the random oracle are executed until all kappa c_indices have been determined. The bug fix shifts the extra_bits value by one bit in each loop iteration so that the LSB of each index is random. Also iterate through the hash array using the loop variable j not the c_indices variable i.

* ike-rekey: Reset IKE_SA on bus before sending CREATE_CHILD_SA responseTobias Brunner2015-07-271-1/+2
| | | | | Even when there is no error the CREATE_CHILD_SA response should be sent in the context of the existing IKE_SA.
* ike-rekey: Reset IKE_SA on the bus after destroying new IKE_SATobias Brunner2015-07-271-16/+15
| | | | | | | | | | | | | | | The destroy() method sets the IKE_SA on the bus to NULL, we reset it to the current IKE_SA so any events and log messages that follow happen in the correct context. A practical example where this is problematic is a DH group mismatch, which causes the first CREATE_CHILD_SA exchange to fail. Because the SA was not reset previously, the message() hook for the CREATE_CHILD_SA response, for instance, was triggered outside the context of an IKE_SA, that is, the ike_sa parameter was NULL, which is definitely not expected by several plugins. Fixes #862.
* Merge branch 'trap-shunt-updates'Tobias Brunner2015-07-274-43/+193
|\ | | | | | | | | | | | | | | | | | | Changes how acquires are tracked in the trap manager, which fixes several race conditions. Also fixes races between threads installing trap policies and the main thread trying to flush the trap policies. Similar changes were added to the shunt manager which previously used no locking at all. Fixes #1014.
| * daemon: Flush shunts before unloading pluginsTobias Brunner2015-07-271-0/+4
| |
| * shunt-manager: Add flush() method to properly uninstall shuntsTobias Brunner2015-07-272-4/+46
| | | | | | | | | | This will allow us to uninstall shunts before unloading the kernel-interface plugins.
| * shunt-manager: Remove stored entries if installation failsTobias Brunner2015-07-271-2/+11
| |
| * shunt-manager: Add a lock to safely access the list of shunt policiesTobias Brunner2015-07-271-3/+17
| |
| * trap-manager: Resolve race conditions between flush() and install()Tobias Brunner2015-07-271-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | When flush() is called there might be threads in install() waiting for trap policies to get installed (without holding the lock). We have to wait until they updated the entries with the respective CHILD_SAs before destroying the list. We also have to prevent further trap policy installations (and wait until threads in install() are really finished), otherwise we might end up destroying CHILD_SA objects after the kernel interface implementations have already been unloaded (avoiding this is the whole point of calling flush() before unloading the plugins).
| * trap-manager: Changed how acquires we acted on are trackedTobias Brunner2015-07-271-36/+86
| | | | | | | | | | | | | | | | | | This fixes potential race conditions in case complete() or flush() is executed before or concurrently with a thread that handles an acquire. It will also simplify tracking multiple acquires created for the same trap policy in the future. Also fixes the behavior in some error situations.
| * trap-manager: Properly check-in IKE_SA if initiating failsTobias Brunner2015-07-271-2/+2
|/ | | | | | | | | This basically reverts f4e822c1b422 ("trap-manager: don't check-in nonexisting IKE_SA if acquire fails"). As checkout_by_config() could return an already existing and established IKE_SA we have to properly destroy it, for instance, in case other threads are waiting to check it out. checkin_and_destroy() should handle the case of a new SA properly (it produces a log message on level 1, though).
* ike: Fall back to the current remote IP if it resolves to %anyTobias Brunner2015-07-271-1/+6
| | | | | | | | | In some situations it might be valid for a host that configures right=%any to reestablish or reauthenticate an IKE_SA. Using %any would immediately abort the initiation causing the new SA to fail (which might already have the existing CHILD_SAs assigned). Fixes #1027.
* Merge branch 'remote-host-family'Tobias Brunner2015-07-278-2/+203
|\ | | | | | | | | | | | | Considers the address family of locally defined addresses when resolving the remote host. Fixes #993.
| * ike: Use address family of local address when resolving remote hostTobias Brunner2015-07-271-1/+14
| | | | | | | | | | | | | | If static local addresses are configured we should use their address family as a hint when resolving the remote address. We don't do this if %any is configured as this might break existing configurations (%any4 and %any6 are however used as hint).
| * ike-cfg: Add unit tests for ike_cfg_get_family() helperTobias Brunner2015-07-273-0/+120
| |
| * ike-cfg: Add helper function to determine address family of IP addressesTobias Brunner2015-07-272-1/+59
| | | | | | | | | | All configured static addresses (hostnames, ranges or subnets are not considered) must be of the same family, otherwise AF_UNSPEC is returned.

* ike-sa-manager: Safely access the RNG instance with an rwlockTobias Brunner2015-07-141-5/+16
| | | | | | | | | | | Threads might still be allocating SPIs (e.g. triggered by an acquire or an inbound message) while the main thread calls flush(). If there is a context switch right after such a thread successfully checked this->rng in get_spi() and the main thread destroys the RNG instance right then, that worker thread will cause a segmentation fault when it continues and attempts to call get_bytes(). Fixes #1014.
* vici: Asynchronize debug loggingMartin Willi2015-07-121-1/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vici logger uses the listener_t.log() callback to raise vici events. When doing so, it holds the bus lock as reader while acquiring the vici socket mutex (1). If at the same time the vici socket enables a writer, that thread tries to lock the watcher mutex (2). The watcher thread uses debugging while holding the lock, i.e. acquires the bus read lock (3). (1) bus.rlock -> vici.lock! (2) vici.lock -> watcher.lock! (3) watcher.lock -> bus.rlock! This all actually would resolve just fine, as we have a shared read lock on the bus. However, under Windows we seem to have a strict writer preference when acquiring the rwlock (4). This results in blocking read locks until any pending write lock can be fulfilled, and makes the constellation deadlock.

It's actually never good practice to acquire shared locks during bus hooks, as it is problematic if we raise bus events while holding the lock. We do so by raising vici events for log message asynchronously, but of curse must keep log order as is using a synchronized queue.

| * chapoly: Process two Poly1305 blocks in parallel in SSSE3 driverMartin Willi2015-07-121-85/+291
| | | | | | | | | | | | | | | | | | | | By using a derived key r^2 we can improve performance, as we can do loop unrolling and slightly better utilize SIMD instructions. Overall ChaCha20-Poly1305 performance increases by ~12%. Converting integers to/from our 5-word representation in SSE does not seem to pay off, so we work on individual words.
