The stress test could reproduce the previously suspected issue of "pop_freelist()+push_freelist() after remove_node() in pj_timer_heap_poll()", here is a bit more description on it:.Creating a stress test for timer heap to reproduce the issue could be useful in identifying the problem and verifying a future solution. There have been some reports about crash in timer heap (there was #2172, but reported that crash still occurs even after integrating the patch). So the auto transmission already happens in inv_send_ack() of sip_inv.c, even though app hasn't sent the ACK. * retransmission of this ACK request from the cache will be doneīut actually pjsip_inv_create_ack() is the one that saves inv->last_ack. * will not cause this callback to be called, and instead automatic * Once it has sent the ACK request, the framework will keep app implements on_send_ack() and calls pjsip_inv_create_ack(), but have not sent it.Thanks to Hugo Lefeuvre for the report and initial patch.ĭelayed sending of ACK request (using on_send_ack() ) may prematurely send the ACK

This patch will not allow adding more cipher once the local array is full. When using GnuTLS, tls_init() will save cipher suite info to local array and might raise out of bound error if GnuTLS has more supported cipher suite then the maximum array size ( MAX_CIPHERS=100 ). In this case, call state callback on_call_state() will be invoked to notify application about call disconnection.įix out of bound error when enabling GnuTLS However, actually there is still a chance of failure in further step of call verification, so the call may get rejected by the library after incoming call callback is invoked. In this case, when the check fails then on_incoming_call() will not be called. The patch will add check for codec and capability support from the SDP beforeĬalling on_incoming_call(). Unfortunately, there is a bug in the library that application will not be informed about the call disconnection in such scenario. However, after the on_incoming_call() invocation, there is a chance that the call is disconnected by the library (e.g: due to unsupported codec or unsupported SIP capability requirement). Ticket #1916 enables on_incoming_call() called from on_create_media_transport() for PJSUA2. On PJSUA2, application will not be notified when when SDP nego fails due to unsupported codec. Thanks Keerthi Kumar Thovi for the report and the analysis. Note that the pj_grp_lock_dec_ref() may cause group lock ref count reaching zero, where all member objects of the group lock will invoke their destructors (usually freeing up any memory allocations), so the next pj_grp_lock_dec_ref() will access invalid/freed memory address. This is a bad news if at the same time the entry callback is being invoked by pj_timer_heap_poll() as pj_grp_lock_dec_ref() will be called after the callback returns. Unfortunately the cancel_timer() does not check the count returned by cancel() and always proceed further with pj_grp_lock_dec_ref(). The cancel() inside cancel_timer() returns zero when a timer entry is invalid or its expiration callback is being invoked (as the entry is removed already). This ticket will filter the frame quality by inspecting the return code of the decoder, i.e: drop the frame if some specific error codes are returned ( dsRefLost dsNoParamSets, dsDepLayerLost).Ĭrash due to double reference decrements in timer The OpenH264 decoder may return non- dsErrorFree and still produce a frame usually with some noise.
