Describe the bug

Assertion failed in registering to stun server

16:01:07.080 pjsua_acc.c ..Acc 0: Registration sent registering... 16:01:07.145 stunresolve .STUN mapped address found/changed: XX.XXX.11.166:19158 16:01:07.146 pjsua_core.c .STUN resolution success, using 193.140.74.144:3478, address is <STUN_IP>:<STUN_PORT> Assertion failed: (ssock->send_buf.max_len == 0), function ssock_on_connect_complete, file ../src/pj/ssl_sock_imp_common.c, line 1134.

Steps to reproduce

void PJSua2::createLib() {
    try {
        ep->libCreate();
    } catch (Error& err){
        std::cout << "Startup error: " << err.info() << std::endl;
    }
    
    //LibInit
    try {
        ep->libInit( *ep_cfg );
    } catch(Error& err) {
        std::cout << "Initialization error: " << err.info() << std::endl;
    }
    
    // Create SIP transport. Error handling sample is shown
    try {
    TransportConfig tcfg;
    
    //TLS
    pjsip_cfg();
    tcfg.tlsConfig.method = PJSIP_TLSV1_3_METHOD;
    tcfg.port = 0; //-> Check w/zero
    ep->transportCreate(PJSIP_TRANSPORT_TLS, tcfg);
    ep->transportCreate(PJSIP_TRANSPORT_UDP, tcfg);

    } catch(Error& err) {
    std::cout << "Transport creation error:" << err.info() << std::endl;
    }

    try { ep->libStart();

After even these situation, didn't crash.

Since you've mentioned it is race condition, it might be happen again. I'll update the issue please keep it open.

But anyway normally it was crashing with same logs, we can assume that the issue solved. Thank you.

It is reduced the percentage of assertion failed for sure but anyway no luck.

Address sanitizer on:

If i get same thing w/sanitizer on i'll update it again.

I would recommend to turn on SSL_DEBUG (define it as 1 in ssl_sock_apple.m). Then when the issue happens again, please provide us the complete log (as text attachment).

I've changed like this:

Idk idea behind this but, while i'm testing with this merge, iphone 12 (iosv: 14.6-18F72) always crashed. However iphone 7 (iosv: 13.3 17C54) didn't crash. Probably i'm going to use openSSL if something goes wrong i'll update the issue.

Same thing happens w/openSSL as well.

Okay, it seems to mean that this is a generic SSL issue and not related to a particular backend.

A few suggestions:

  • I see from your log that you are using 2.10-dev, so test with the latest branch instead.
  • Try with our sample app. If not, attach your small sample app you use to reproduce the issue so we can test it ourselves locally.

It's not related with 2.10-dev actually I've already merged with 2.11 and some 2.12 pr, but no way.

The interesting things is that: this is happens only my iPhone 12 iOS 14.6 phone, others are okay. But anyway something goes wrong for sure.

Currently I cannot provide the sample app because of I'm using third party media stack, instead of the phone audio, but above in my first comment I've provided the source code of pjsua2 level. Pjsip is same with 2.11 just using third party media stack.

I don't have the issue with sample apps you provided or pjsua2 swift sample app which is provided by me before. It might be related with media stack, or idk for now. I'll keep the update this issue.

[UPDATE]
This is the log which includes more details:

The issue solved, it is because of my side.

I'm creating the timer like that
   let timer = Timer.scheduledTimer(withTimeInterval: 10, repeats: true) { timer in
CPPWrapper().register(//configs);
}

without fire it.

I've added following part and issue resolved.

        DispatchQueue.global().asyncAfter(deadline: DispatchTime.now()) {
                if(!timer.isValid){
                    timer.fire()
                }
            }

I'm closing this one, thank you for your collaboration.

This isn't resolved for iPhone 12 - iOS 14.6

Tested with iPhone 7, iPhone XR they're all okay.

I've merged with the 14.02.2022's commits so this is latest one.

Just like previous suggestions:

  • Test with OpenSSL backend. You mentioned that the assertion happened when using OpenSSL as well, is this still the case?
  • When using Apple SSL backend, turn on SSL_DEBUG (change the definition to 1 in ssl_sock_apple.m)
  • Test with the sample app. You mentioned that using sample app triggered no assertion. If this is so, modify the sample app in order to incorporate what you do in your app until the assertion is triggered. From the log, it shouldn't be related to third party media since the assertion occurred only after a simple registration request.

The double event posts for every event seems weird, and it also happened on the success case.

14:53:17.746       ssl_sock_apple.m !Posting event 0x11804c828 1
14:53:17.746       ssl_sock_apple.m  Post event success 0x11804c828 1
14:53:17.746       ssl_sock_apple.m  Posting event 0x11804c828 1
14:53:17.746       ssl_sock_apple.m  Post event success 0x11804c828 1

My suggestion is to try with ipjsua, instead of pjsua2 swift, since you can immediately use the former for testing without much modification. All you need to do is pass the parameters, such as in ipjsuaAppDelegate.m:

    const char *argv[] = { "pjsua",
        "--use-cli",
        "--no-cli-console",
        "--cli-telnet-port=0",
        "--id=xxx<sip:[email protected]>",
        "--realm=*",
        "--username=xxx",
        "--password=xxxx",
        "--registrar=sip:sip.xxx.org;transport=tls",
        "--use-tls",
        NULL };
    int argc = PJ_ARRAY_SIZE(argv) -1;

Also test with ipjsua and OpenSSL. I tried it here on iPhone 12 with iOS 15.2.1 running OpenSSL 1.1.1m, and it worked fine.

If ipjsua and OpenSSL works fine (this is to rule out app and generic SSL issue/bug), AND ipjsua with Apple SSL still shows the same problem (double events), please provide us with your test server credentials so we can test it here. You can encrypt the information using the key that can be found in https://github.com/pjsip/pjproject/security/policy and attach the text file here.

Seems working with the OpenSSL. But unfortunately cannot build for Third Party Library.

First it gives
"error: implicit declaration of function 'check_srtp_roc' is invalid in c99 [-werror,-wimplicit-function-declaration]"
Configure logs:
config.log

Then I declared it as to line 34 in pjsua_media.c

void check_srtp_roc(pjsua_call *call,
			   unsigned med_idx,
			   const pjsua_stream_info *new_si_,
    			   const pjmedia_sdp_media *local_sdp,
    			   const pjmedia_sdp_media *remote_sdp);

This is solved PJSIP build issue but after that when I'm building for samples it gives me:
After solved the issue build log is:
iphone-build.log

And PJSIP apps build log is this:
pjsipapps-build.log

@sauwming Sorry for late response, it takes time. Could you check and reply it?

All logs are encrypted with your public key as gpg format.

Please try the attached patch.
apple_ssl_patch.txt

It should prevent the assertion from happening. What I'm not sure is if this will eventually lead to a successful registration.

Seems it is solved. But there is no exact way to handle this error. Sometimes i cannot reproduce the error. I've build without patch then with patch. When i compared both it seems solved but as i said i'll check it by time.

For now it can be hotfix. Thank you.

Okay, update us if the issue is completely solved after more extended testing with the patch.

Still i haven't face with the same issue. We can assume that, the issue is solved. I'm leaving the comment it's up to you close or leave the issue like that. @sauwming

After a month usage i can say that the issue still persist. I'll send logs when i handle next time. But the issue is now:

Above problem is resolved it's okay but when using pjsua2-swift with AppleSSL sometimes (Especially during the call state) getting invalid turn server settings log. And this is seems crash (actually behavior is same with pressing home button w/ iphone) it goes to background like pressing homebutton and callstop but app is not crashing.

This logs coming with openSSL also but there is no such behavior. It can continue to working.

Something like:
