2023-03-14session vcl: refactor builtin tx event for main txFlorin Coras7-30/+33
Rename unused SESSION_IO_EVT_BUILTIN_TX to SESSION_IO_EVT_TX_MAIN and leverage it for non-connected udp tx. Non-connected udp sessions are listeners and are therefore allocated on main thread. Consequently, whenever session queue node is not polling main, tx events generated by external applications might be missed or processed with some delay. To solve this, request that apps use SESSION_IO_EVT_TX_MAIN tx events as opposed to SESSION_IO_EVT_TX and send that to first worker as opposed to main.

2023-03-08session: Use session->thread_index to correctly retrieve the sessionSteven Luong1-1/+3
For non-connected udp, when retrieving the subscriber session to send the notification, it uses the current worker thread index whereas the subscriber session is actually on the main thread. Using the worker thread may cause a crash since the corresponding session may not be valid in the worker thread context and even if it is valid, it is the wrong session. This scenario is seen when the application forks and adds subscribers to the worker thread session.

2023-03-06crypto: remove VNET_CRYPTO_OP_FLAG_INIT_IV flagBenoît Ganne1-3/+2
IV requirements vary wildly with the selected mode of operation. For example, for AES-CBC the IV must be unpredictable whereas for AES counter mode (CTR or GCM), it can be predictable but reusing an IV with the same key material is catastrophic. Because of that, it is hard to generate IV in a generic way, and it is better left to the crypto user (eg. IPsec).
