* testing: Fix CRL URIs in ipv6/net2net-ip4-in-ip6-ikev* scenariosTobias Brunner2015-11-092-2/+2
|
* testing: Speed up OCSP scenariosTobias Brunner2015-11-093-4/+4
| | | | | Don't make clients wait for the TCP connections to timeout by dropping packets. By rejecting them the OCSP requests fail immediately.
* testing: Speed up ifdown calls in ikev2/mobike scenariosTobias Brunner2015-11-093-1/+13
| | | | | | ifdown calls bind's rndc, which tries to access TCP port 953 on lo. If these packets are dropped by the firewall we have to wait for the TCP connections to time out, which takes quite a while.
* testing: Avoid delays with ping by using -W and -i optionsTobias Brunner2015-11-0933-55/+55
| | | | | | With -W we reduce timeouts when we don't expect a response. With -i the interval between pings is reduced (mostly in case of auto=route where the first ping yields no reply).
* testing: Remove nearly all sleep calls from pretest and posttest scriptsTobias Brunner2015-11-09303-452/+500
| | | | | By consistently using the `expect-connection` helper we can avoid pretty much all previously needed calls to sleep.
* ikev1: Fix calculation of DPD timeoutTobias Brunner2015-11-091-0/+2
| | | | | A DPD timeout job is queued whenever a DPD is sent, i.e. after the DPD delay already has elapsed, so we have to compensate for that.
* testing: Adapt tests to retransmission settings and reduce DPD delay/timeoutTobias Brunner2015-11-0926-43/+43
|
* ipsec: Quit script quicker for ipsec stopTobias Brunner2015-11-091-2/+2
| | | | | | | It rarely takes 1 second or longer to terminate the daemon. This decreases the runtime of the post test step a lot where `ipsec stop` is called for multiple hosts in each test case (10-15 minutes over all test cases).
* testing: Only send two retransmits after 1 second each to fail negative ↵Tobias Brunner2015-11-091-0/+6
| | | | tests earlier
* testing: Add a base strongswan.conf file used by all hosts in all scenariosTobias Brunner2015-11-092-0/+2
| | | | | | We will use this to set some defaults (e.g. timeouts to make testing negative tests quicker). We don't want these settings to show up in the configs of the actual scenarios though.
* xauth: Call authorize() hook also when xauth-noauth is usedTobias Brunner2015-11-091-2/+8
| | | | Fixes #1138.
* libtnccs: Optionally use RTLD_NOW to load IMC/IMVs with dlopen()Tobias Brunner2015-11-093-4/+16
|
* plugin-loader: Optionally use RTLD_NOW with dlopen()Tobias Brunner2015-11-092-6/+15
| | | | | | | | | This can be useful when writing custom plugins as typos or missing linker flags that result in unresolved symbols in the shared object could otherwise cause late crashes. In particular, if such a symbol is used in a code path that is rarely executed. During development and testing using RTLD_NOW instead of RTLD_LAZY will prevent the plugin from getting loaded and makes the error visible immediately.
* windows: Define RTLD_NOW, even if it is not usedTobias Brunner2015-11-091-0/+5

* kernel-pfkey: Enable ENCR_AES_CTR when it's availableRenato Botelho2015-11-091-1/+3
| | | | | | Obtained-from: pfSense Sponsored-by: Rubicon Communications (Netgate) Closes strongswan/strongswan#17.
* vici: Add NAT information when listing IKE_SAsTobias Brunner2015-11-092-0/+21
| | | | | | | | | | The `nat-local` and `nat-remote` keys contain information on the NAT status of the local and remote IKE endpoints, respectively. If a responder did not detect a NAT but is configured to fake a NAT situation this is indicated by `nat-fake` (if an initiator fakes a NAT situation `nat-local` is set). If any NAT is detected or faked `nat-any` is set. Closes strongswan/strongswan#16.
* Merge branch 'iv-gen-null-encr'Tobias Brunner2015-11-0916-1/+1348
|\ | | | | | | | | | | Fixes NULL encryption in libipsec. Fixes #1174.
| * testing: Add libipsec/net2net-null scenarioTobias Brunner2015-11-0911-0/+1245
| |
| * iv-gen: Use NULL IV generator for NULL encryptionTobias Brunner2015-11-091-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | We don't need an IV for NULL encryption, so we wouldn't technically need an IV generator. But some of the code currently relies on an IV generator to be present. So we don't have to change that code and handle IV size == 0 specially we use the new NULL IV generator, which handles this transparently to the existing code. Before 3c81cb6fc322 ("aead: Create AEAD using traditional transforms with an explicit IV generator") iv_gen_rand_t was used for NULL encryption, which would work too but this way it's clearer.
| * crypto: Add NULL IV generatorTobias Brunner2015-11-094-1/+98
|/ | | | | This does not actually allocate an IV and only accepts requests for size == 0.
* configure: Load sha1 and random plugins in manager by defaultTobias Brunner2015-11-091-3/+3
| | | | | | | | | If the openssl plugin is not enabled we need these to generate session IDs and to authenticate the users. The md4 plugin is not needed in the manager. Fixes #1168.

|
* testing: Update tkm to version 0.1.3Tobias Brunner2015-10-301-1/+1
| | | | | | Adds XFRM state/policy flush when terminating which caused tests to fail due to the check added with 9086f060d35a ("testing: Let test scenarios fail if IPsec SAs or policies are not removed").
* libipsec: Properly support CAMELLIA in CTR modeTobias Brunner2015-10-301-0/+1
|
* ikev2: Fix size of key material for CAMELLIA-CTRTobias Brunner2015-10-301-0/+1
| | | | Like AES in CTR mode it includes a 4 byte nonce.
* libipsec: Fix crypter lookup for AES-CTRTobias Brunner2015-10-301-1/+12
| | | | | | | | | | | | Due to the nonce, the ESP key material is four bytes longer than needed for the actual AES key. The crypto plugins, however, register their AES-CTR implementations with the AES key length, so the lookup here failed. For IKEv2 the key material is allocated after creating a crypter instance with the negotiated AES key size. The length of the actual key material is retrieved via get_key_size(), which adds the four bytes to the AES key length. Fixes #1124.
* ike-mobike: Send retransmits to the current local and remote addressesTobias Brunner2015-10-301-1/+5
| | | | | | These might have changed by a peer-initiated MOBIKE address update. Fixes #1125.
* Merge branch 'ikev1-cache-informational'Tobias Brunner2015-10-301-15/+81
|\ | | | | | | | | | | | | | | | | | | | | | | | | With these changes an INFORMATIONAL message (e.g. with an INITIAL_CONTACT notify) that arrives while a responder is waiting for the last Aggressive Mode request gets queued and delivered later. Previously such messages caused the IKE_SA to fail as some tasks waiting for the last AM message fail when trying to handle the INFORMATIONAL message. Therefore, all other messages, such as TRANSACTION and QUICK_MODE requests, are now dropped until AM is complete. These don't have to be cached as they get retransmitted by the other peer. Fixes #1130.

* ikev1: Make maximum number of IKEv1 phase 2 exchanges we keep state about ↵Tobias Brunner2015-10-302-9/+15

* Fix typo in error handling for sigwaitinfo() in charon-systemd and charon-tkmTobias Brunner2015-10-292-2/+2
| | | | Fixes 858148092d1e ("Replace usages of sigwait(3) with sigwaitinfo(2)")
* random: Properly handle errors when reading from /dev/[u]randomTobias Brunner2015-10-291-0/+1
| | | | | | | | If -1 was returned on the first call to read() `done` got SIZE_MAX and the function returned TRUE even though no actual random data had been allocated. Fixes #1156.
* ikev1: Avoid fourth QM message if third QM messages of multiple exchanges ↵Tobias Brunner2015-10-292-2/+14
| | | | | | | | | | | | are handled delayed If we haven't received the third QM message for multiple exchanges the return value of NEED_MORE for passive tasks that are not responsible for a specific exchange would trigger a fourth empty QM message. Fixes: 4de361d92c54 ("ikev1: Fix handling of overlapping Quick Mode exchanges") References #1076.
* ikev1: Prevent deadlock when checking for duplicate IKEv1 SAsTobias Brunner2015-10-291-0/+16
| | | | | | | | | | | Previously, the current segment was held while checking for duplicate SAs, which requires acquiring all segments. If multiple threads did this concurrently this resulted in a deadlock as they couldn't acquire the segments held by the other threads attempting to do the same. With the default configuration only one segment is used, which prevents the problem as only one thread can check in an IKE SA concurrently. Fixes: a064eaa8a63a ("Handling of initial contact")
* Replace usages of sigwait(3) with sigwaitinfo(2)Tobias Brunner2015-10-299-36/+31
| | | | | | | This is basically the same call, but it has the advantage of being supported by FreeBSD's valgrind, which sigwait() is not. References #1106.
* testing: Actually send an uncompressed packet in the ipv6/rw-compress-ikev2 ↵Tobias Brunner2015-10-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | scenario The default of 56 bytes already exceeds the threshold of 90 bytes (8 bytes ICMP + 40 bytes IPv6 = 104 bytes). By reducing the size we make sure the packet is not compressed (40 + 8 + 40 = 88). This also fixes a strange failure of this scenario due to the recently added post-test `ip xfrm state` check. The kernel stores a reference to the used SAs on the inbound skbuffs and since these are garbage collected it could take a while until all references to an SA disappear and the SA is finally destroyed. But while SAs might not get destroyed immediately when we delete them, they are actually marked as dead and therefore won't show up in `ip xfrm state`. However, that's not the case for the tunnel SAs the kernel attaches to IPComp SAs, which we don't explicitly delete, and which aren't modified by the kernel until the IPComp SA is destroyed. So what happened when the last ping unintentionally got compressed is that the skbuff had a reference to the IPComp SA and therefore the tunnel SA. This skbuff often was destroyed after the `ip xfrm state` check ran and because the tunnel SA would still get reported the test case failed.
