Hi PJSIP team,
Could this patch be considered for inclusion in the project?
This issue is causing segfaults a least once a day.
Kind regards,
Ross From: pjsip <pjsip-bounces@xxxxxxxxxxxxxxx> on behalf of Alexei Gradinari <alex2grad@xxxxxxxxx>

On heavy loaded system with TLS, one thread could destroy the ssl socket on SSL_ERROR_SYSCALL while another thread still uses this socket which was already freed, so we get segfault. Attached 2 backtraces. To avoid race condition need to lock the socket before destroying it. The attached patch adds the socket lock on destroying it and adds a checking on all openssl calls that the socket wasn't destroyed. Regards, Alexei |
