* ikev2: Add option to disable following redirects as clientTobias Brunner2016-03-041-0/+3

* ikev1: Allow immediate deletion of rekeyed CHILD_SAsTobias Brunner2016-03-031-0/+8
| | | | | | | | | | | | | | | When charon rekeys a CHILD_SA after a soft limit expired, it is only deleted after the hard limit is reached. In case of packet/byte limits this may not be the case for a long time since the packets/bytes are usually sent using the new SA. This may result in a very large number of stale CHILD_SAs and kernel states. With enough connections configured this will ultimately exhaust the memory of the system. This patch adds a strongswan.conf setting that, if enabled, causes the old CHILD_SA to be deleted by the initiator after a successful rekeying. Enabling this setting might create problems with implementations that continue to use rekeyed SAs (e.g. if the DELETE notify is lost).
* ikev1: Always enable charon.reuse_ikesaTobias Brunner2016-02-011-1/+1
| | | | | | | | | With IKEv1 we have to reuse IKE_SAs as otherwise the responder might detect the new SA as reauthentication and will "adopt" the CHILD_SAs of the original IKE_SA, while the initiator will not do so. This could cause CHILD_SA rekeying to fail later. Fixes #1236.

* libtnccs: Optionally use RTLD_NOW to load IMC/IMVs with dlopen()Tobias Brunner2015-11-091-2/+2

* plugin-loader: Optionally use RTLD_NOW with dlopen()Tobias Brunner2015-11-091-0/+4
| | | | | | | | | 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.

* eap-radius: Change trigger for Accounting Start messages for IKEv1Tobias Brunner2015-08-061-1/+1
| | | | | | | | | | | | | | | | | | | | | Some clients won't do Mode Config or XAuth during reauthentication. Because Start messages previously were triggered by TRANSACTION exchanges none were sent for new SAs of such clients, while Stop messages were still sent for the old SAs when they were destroyed. This resulted in an incorrect state on the RADIUS server. Since 31be582399 the assign_vips() event is also triggered during reauthentication if the client does not do a Mode Config exchange. So instead of waiting for a TRANSACTION exchange we trigger the Start message when a virtual IP is assigned to a client. With this the charon.plugins.eap-radius.accounting_requires_vip option would not have any effect for IKEv1 anymore. However, it previously also only worked if the client did an XAuth exchange, which is probably rarely used without virtual IPs, so this might not be much of a regression. Fixes #937.
* kernel-netlink: Use PAGE_SIZE as default size for the netlink receive bufferTobias Brunner2015-08-041-1/+1
| | | | | | | | The kernel uses NLMSG_GOODSIZE as default buffer size, which defaults to the PAGE_SIZE if it is lower than 8192 or to that value otherwise. In some cases (e.g. for dump messages) the kernel might use up to 16k for messages, which might require increasing this value.

* trap-manager: Add option to ignore traffic selectors from acquire eventsTobias Brunner2015-03-231-0/+11
| | | | | | | | The specific traffic selectors from the acquire events, which are derived from the triggering packet, are usually prepended to those from the config. Some implementations might not be able to handle these properly. References #860.
* kernel-pfkey: Add option to set receive buffer size of event socketTobias Brunner2015-03-062-0/+8
| | | | | | | | If many requests are sent to the kernel the events generated by these requests may fill the receive buffer before the daemon is able to read these messages. Fixes #783.
* ikev2: Add an option to disable constraints against signature schemesTobias Brunner2015-03-041-0/+8
| | | | | | | | | | If this is disabled the schemes configured in `rightauth` are only checked against signature schemes used in the certificate chain and signature schemes used during IKEv2 are ignored. Disabling this could be helpful if existing connections with peers that don't support RFC 7427 use signature schemes in `rightauth` to verify certificate chains.

* mem-pool: Pass the remote IKE address, to re-acquire() an address during reauthMartin Willi2015-02-201-4/+0
| | | | | | | | | | | With make-before-break IKEv2 re-authentication, virtual IP addresses must be assigned overlapping to the same peer. With the remote IKE address, the backend can detect re-authentication attempts by comparing the remote host address and port. This allows proper reassignment of the virtual IP if it is re-requested. This change removes the mem-pool.reassign_online option, as it is obsolete now. IPs get automatically reassigned if a peer re-requests the same address, and additionally connects from the same address and port.
