* Add missing openssl SECLEVEL=0 support (pjsip#3890) Previous SECLEVEL support allowed for levels 1-5. However, openssl defines levels 0-5. [1] Recent openssl versions (3.0+) have moved previous popular ciphers/key lengths (i.e. RSA1024withSHA1) into level 0, so it is now a reasonable choice to use. Add support for level 0.

There may be an issue with the stream using the media transport's group lock since their lifetime can be different. For every media update, stream can be destroyed and recreated, but since it's tied to transport, now it won't be destroyed. To test the issue: make a call, repeatedly hold and reinvite. |
|
If the stream creates its own group lock, and every callback is protected (add/dec ref before/after the callback), will it still solve the original issue #3956? |
|
Yeah, I think it should work. |

To fix #3956.
Stream & transport still access their internal states after being destroyed by the call hangup invoked from within transport callback.
The fix is to move pool release to the transport's group lock handler. Also for added protection, add check for UDP transport validity after invoking callback.
Thanks @R-Jeske for the detailed report.
