2020-03-26ikev2: fix wrong usage of BN_bn2bin()Filip Tehlar3-12/+56
This patch fixes 2 different crashes: 1) BN_bn2bin() returns bytes written, not actual key length. Use BN_bn2binpad() instead which adds padding. 2) Initiator may receive multiple sa-init responses for the same ispi which may result in crash. Remember first response and ignore any subsequent ones.

2020-02-17ikev2: IKE plugin manages the state of the protected tunnel interfaceNeale Ranns1-2/+8
Type: improvement IKE will bring the tunnel up ince the negociation is complete and bring it down when the session ends. It is the clinets responsibility to manage the state of the tunnel before and after these events. So to prevent any unencrpyted traffic egressing the tunnel before the session is negpciated, the tunnel should be in the down state when it a associated with the IKE session.

2019-07-09vat: unload unused vat pluginsDave Barach1-19/+2
If the corresponding vpp plugin is absent, return a non-zero clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The vat plugin calls dlclose on the vat plugin, and it disappears. Depending on the plugin configuration, this can reduce the vpp virtual size by several gigabytes. Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up boilerplate vat_plugin_register() implementations. Fixed a number of non-standard vat_plugin_register methods.
