* ikev1: Make maximum number of IKEv1 phase 2 exchanges we keep state about ↵Tobias Brunner2015-10-301-9/+11
| | | | | | configurable Fixes #1128.
* 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.
* updown: Add rules to allow IP6IP6 traffic used for uncompressed small packetsTobias Brunner2015-09-211-0/+31
|
* shunt-manager: Resolve %dynamic to %any4/6 before installing policiesTobias Brunner2015-09-161-7/+22
| | | | | | | | left|rightsubnet default to %dynamic, which is basically 0.0.0.0/0 until an address is assigned to it. So if only one side was undefined and the other traffic selector was IPv6 an address family mismatch would occur. References #595.
* shunt-manager: Don't install policies in case of an address family or IP ↵Tobias Brunner2015-09-161-0/+20
| | | | | | protocol mismatch References #595.
* openssl: Explicitly include openssl/bn.hTobias Brunner2015-09-165-0/+5
| | | | | | | | If OpenSSL is compiled with OPENSSL_NO_DEPRECATED some of the headers we include don't include openssl/bn.h anymore. Therefore, we have to explicitly include it ourselves where we use BN_* functions. Fixes #1113.
* unit-tests: Add a test to verify that there is no partial matching of RDNsTobias Brunner2015-09-091-0/+1
|
* scepclient: Remove copyright and license from man pageTobias Brunner2015-09-091-9/+0

* include: Add linux/socket.hTobias Brunner2015-09-072-1/+22
| | | | | | | | | | | | | __kernel_sa_family_t is defined and used since Linux 3.1, so on systems with older kernels (like CentOS 6.7, which still ships a 2.6.32 kernel) the build with the current UAPI headers fails. And using the native headers on such system does not really work either because we use structs, defines, and enum values from the newer headers in the kernel-netlink plugin. __kernel_sa_family_t is defined in linux/socket.h so we ship that too (in particular the simplified UAPI version from Linux 3.7+). Fixes #1099.
* imv-os: Add some useful usage output to the pacman utilityTobias Brunner2015-08-311-2/+8
| | | | Fixes #487.
* kernel-netlink: Properly set port mask for ICMP type/code if only set on one ↵Tobias Brunner2015-08-311-7/+8
| | | | | | | | | | | | side If only one traffic selector had a port (type/code) the other side had the port mask set to 0, which canceled out the applied type/code. It also fixes the installation of ICMP type/code on big-endian hosts. Fixes #1091. References #595.
* kernel-pfkey: Properly encode ICMP type/code if only set on one sideTobias Brunner2015-08-311-34/+20
| | | | References #595.
* libimcv: Updated Android.mk fileTobias Brunner2015-08-311-2/+5

* eap-radius: Fix creation of host_t objects based on Framed-IPv6-Address ↵Tobias Brunner2015-08-281-1/+1
| | | | | | | attributes Fixes ec490e68ae37 ("eap-radius: Add support for some basic IPv6-specific RADIUS attributes"). References #1001.
* pki: Add new type options to --issue command usage outputTobias Brunner2015-08-271-2/+2

|
* traffic-selector: Use calc_netbits() in RFC 3779 constructorTobias Brunner2015-08-271-2/+1
| | | | This properly detects prefixes encoded as ranges.
* ike: Fix half-open count for initiating SAs when initially checked inTobias Brunner2015-08-271-0/+6
|
* ike: Only consider number of half-open SAs as responder when deciding ↵Tobias Brunner2015-08-276-19/+45
| | | | whether COOKIEs are sent
* vici: Handle closed sockets in the Ruby gemEvan Broder2015-08-241-1/+5
| | | | | | | | | | | | | | | | From recvfrom(2) (which UDPSocket#recv backs into): The return value will be 0 when the peer has performed an orderly shutdown. (i.e. it will return an empty string) Previously in this scenario, Vici::Transport#recv_all would spin forever trying to pull more data off the socket. I'm not entirely clear what happened that caused strongSwan to shutdown the socket, but it probably should not cause vici Ruby apps to spin. Closes strongswan/strongswan#13.
* starter: Don't flush SAs in the kernelTobias Brunner2015-08-213-14/+0
| | | | | If starter is not used we don't do that either. And this allows us to move the stuff in libhydra back to libcharon.
* starter: Don't flush policies in the kernelTobias Brunner2015-08-211-1/+0
| | | | | | | | | | | We can't control which policies we flush, so if policies are installed and used outside of strongSwan for other protocols we'd flush them too. And if installpolicies=no is used we probably shouldn't flush policies either. Luckily already existing policies are not treated as fatal errors anymore, so not flushing policies should not be that much of an issue (in case of a crash in dynamic setups, e.g. with virtual IPs, policies could be left behind even after restarting the connections and properly terminating the daemon).
* kernel-pfkey: Only flush SAs of types we actually manageTobias Brunner2015-08-211-13/+26

* kernel-netlink: Only flush SAs of types we actually manageTobias Brunner2015-08-211-6/+19
|
* vici: Optionally check limits when initiating connectionsTobias Brunner2015-08-212-1/+7
| | | | | If the init-limits parameter is set (disabled by default) init limits will be checked and might prevent new SAs from getting initiated.
* vici: Add get_bool() convenience getter for VICI messagesTobias Brunner2015-08-213-0/+94
|
* controller: Optionally adhere to init limits also when initiating IKE_SAsTobias Brunner2015-08-2115-20/+71

* ike: Also track initiating IKE_SAs as half-openTobias Brunner2015-08-211-1/+0
|
* stroke: Allow %any as local addressTobias Brunner2015-08-211-3/+7
| | | | | Actually, resolving addresses in `left` might be overkill as we'll assume left=local anyway (the only difference is the log message).
* stroke: Add an option to disable side-swapping of configuration optionsTobias Brunner2015-08-211-33/+46
| | | | | In some scenarios it might be preferred to ensure left is always local and no unintended swaps occur.
* ikev1: Assign different job priorities for inbound IKEv1 messagesTobias Brunner2015-08-211-2/+12

* child-rekey: Don't add a REKEY_SA notify if the child-create task is ↵Tobias Brunner2015-08-211-6/+9
| | | | deleting the SA
* child-create: Cache proposed IPsec protocolTobias Brunner2015-08-211-10/+13
| | | | | This allows us to DELETE CHILD_SAs on failures that occur before we retrieved the selected proposal.
* child-create: Don't attempt to delete the SA if we don't have all the ↵Tobias Brunner2015-08-211-8/+10
| | | | | | | information Since we only support single protocols we could probably guess it and always send a DELETE.
* child-rekey: Remove redundant migrate() call for child-create sub-taskTobias Brunner2015-08-211-2/+1
| | | | | | | When retrying due to a DH group mismatch this is already done by the child-create task itself. And in other cases where the task returns NEED_MORE we actually will need access to a possible proposal to properly delete it.
* child-create: Fix crash when retrying CHILD_SA rekeying due to a DH group ↵Tobias Brunner2015-08-211-0/+1
| | | | | | | | | | mismatch If the responder declines our KE payload during a CHILD_SA rekeying migrate() is called to reuse the child-create task. But the child-rekey task then calls the same method again. Fixes: 32df0d81fb46 ("child-create: Destroy nonceg in migrate()")
* auth-cfg: Don't enforce EAP_RADIUSTobias Brunner2015-08-211-1/+2
| | | | | Basically the same as e79b0e07e4ab. EAP_RADIUS is also a virtual method that will identify itself as a different EAP method later.
* stroke: Change how CA certificates are storedTobias Brunner2015-08-205-58/+285
| | | | | | | | | | | Since 11c14bd2f5 CA certificates referenced in ca sections were enumerated by two credential sets if they were also stored in ipsec.d/cacerts. This caused duplicate certificate requests to get sent. All CA certificates, whether loaded automatically or via a ca section, are now stored in stroke_ca_t. Certificates referenced in ca sections are now also reloaded when `ipsec rereadcacerts` is used.
* stroke: Combine CA certificate load methodsTobias Brunner2015-08-201-82/+74
| | | | | Also use the right credential set for CA cert references loaded from stroke_ca_t.
