Reproduction Steps: 1. Load https://jsfiddle.net/rn8b6y0k/1/ in Safari from an IPv6 network.* 2. Click "Test without getUserMedia". Expected Results: At least one srflx candidate is gathered. Actual Results: No ICE candidates are gathered, "null candidate" is never received, and ICE connection state does not change. * I tested using Safari on iOS with T-Mobile. I also tested Safari on macOS connected through my iPhone's T-Mobile hotspot. I got mixed results through the T-Mobile hotspot (I'm not sure why). My colleague tried the same test on iOS using AT&T, and it worked for him. --- If you re-run this test with Chrome on macOS, it will succeed. 1383411 1 youennf 2017-12-19 16:35:24 -0800 I can reproduce the bug as well. 1383413 2 webkit-bug-importer 2017-12-19 16:38:34 -0800 <rdar://problem/36144555> 1383585 3 svein 2017-12-20 03:33:55 -0800 If a device has both an IPv4 address and an IPv6 address, will this issue affect both? In other words: Are no srflx and relay candidates gathered if the host is on a IPv6 network or does the issue affect only the IPv6 address? 1383690 4 youennf 2017-12-20 09:32:32 -0800 (In reply to sventy from comment #3) > If a device has both an IPv4 address and an IPv6 address, will this issue > affect both? Both host IPv4 and IPv6 should be gathered according my testing. > In other words: Are no srflx and relay candidates gathered if the host is on > a IPv6 network or does the issue affect only the IPv6 address? I would think this only affects the IPv6 addresses. My testing is limited at the moment though. 1406868 5 youennf 2018-03-15 16:06:18 -0700 To be noted that on that page, stun.l.google.com is used and does not have any IPV6 address. It seems therefore strange that a srflx candidate would be gathered. That said, we should not be timing out. Maybe the DNS resolution is timing out and we do not properly handle this error case. Or we are getting an IPv4 address and do not handle it properly. 1419422 6 339224 youennf 2018-05-01 14:22:12 -0700 Created attachment 339224 Patch 1419684 7 339224 commit-queue 2018-05-02 09:42:15 -0700 Comment on attachment 339224 Patch Clearing flags on attachment: 339224 Committed r231235: <https://trac.webkit.org/changeset/231235> 1419685 8 commit-queue 2018-05-02 09:42:17 -0700 All reviewed patches have been landed.

Is it out yet? 1449740 10 youennf 2018-08-13 13:02:25 -0700 (In reply to Mark Roberts from comment #9) > Thanks, Youenn.

The patch should be out since quite some time on Safari Tech Preview and is probably in latest Mac/iOS betas. 339224 2018-05-01 14:22:12 -0700 2018-05-02 09:42:15 -0700 Patch bug-181009-20180501142212.patch text/plain 2506 youennf U3VidmVyc2lvbiBSZXZpc2lvbjogMjMxMTk3CmRpZmYgLS1naXQgYS9Tb3VyY2UvV2ViS2l0L0No YW5nZUxvZyBiL1NvdXJjZS9XZWJLaXQvQ2hhbmdlTG9nCmluZGV4IGI3NWJkY2E5NjdhNTA4NGVk MjZmZWUwMWQ5ZTc5ZDU4NzA4Njk1MzEuLjA3YTBlZWU0MzQ5ZWExOGRjZGYzZDRmZWI5NGUwM2M2 ZGJmZWQwMTkgMTAwNjQ0Ci0tLSBhL1NvdXJjZS9XZWJLaXQvQ2hhbmdlTG9nCisrKyBiL1NvdXJj ZS9XZWJLaXQvQ2hhbmdlTG9nCkBAIC0xLDMgKzEsMjQgQEAKKzIwMTgtMDUtMDEgIFlvdWVubiBG YWJsZXQgIDx5b3Vlbm5AYXBwbGUuY29tPgorCisgICAgICAgIENhbm5vdCBnYXRoZXIgc3JmbHgg b3IgcmVsYXkgSUNFIGNhbmRpZGF0ZXMgb24gSVB2NiBuZXR3b3JrIChJQ0UgYWdlbnQgaGFuZ3M/ KQorICAgICAgICBodHRwczovL2J1Z3Mud2Via2l0Lm9yZy9zaG93X2J1Zy5jZ2k/aWQ9MTgxMDA5 CisgICAgICAgIDxyZGFyOi8vcHJvYmxlbS8zNjE0NDU1NT4KKworICAgICAgICBSZXZpZXdlZCBi eSBOT0JPRFkgKE9PUFMhKS4KKworICAgICAgICBPbiBpT1MvSVB2NiBuZXR3b3JrcywgU1RVTiBz ZXJ2ZXJzIG5hbWUgcmVzb2x1dGlvbiByZXR1cm5zIGEgemVybyBJUHY2IElQIGFkZHJlc3MuCisg ICAgICAgIE5vIGVycm9yIGlzIHJhaXNlZCB3aGljaCBsZWFkcyB0byBzZW5kaW5nIFNUVU4gcmVx dWVzdHMgd2l0aCB0aGF0IElQIGFkZHJlc3MuCisgICAgICAgIE9uY2UgdGhlIHJlcXVlc3QgdGlt ZXMgb3V0LCB0aGUgSUNFIGNhbmRpZGF0ZSBnYXRoZXJpbmcgZmluaXNoZXMgd2l0aCBob3N0IGNh bmRpZGF0ZXMgb25seS4KKworICAgICAgICBUaGlzIHBhdGNoIG1ha2VzIFdlYlJUQyBETlMgcmVz b2x2ZXIgdG8gc2VuZCBvbmx5IElQdjQgcmVzb2x2ZWQgYWRkcmVzc2VzLgorICAgICAgICBTVFVO IGlzIHVzZWQgZm9yIE5BVCB0cmF2ZXJzYWwgd2hpY2ggaXMgZm9yIElQdjQgYWRkcmVzc2VzLgor ICAgICAgICBOb3Qgc2VuZGluZyBJUHY2IGFkZHJlc3NlcyBhbGxvd3MgdGVybWluYXRpbmcgSUNF IGNhbmRpZGF0ZSBnYXRoZXJpbmcgc29vbmVyLgorCisgICAgICAgIE1hbnVhbGx5IHRlc3RlZCBv biBpT1Mgd2l0aCBJUHY0L0lQdjYgYW5kIElQdjYgbmV0d29ya3MuCisKKyAgICAgICAgKiBOZXR3 b3JrUHJvY2Vzcy93ZWJydGMvTmV0d29ya1JUQ1Jlc29sdmVyQ29jb2EuY3BwOgorICAgICAgICAo V2ViS2l0OjpyZXNvbHZlZE5hbWUpOgorCiAyMDE4LTA1LTAxICBPbGVrc2FuZHIgU2thY2hrb3Yg IDxnc2thY2hrb3ZAZ21haWwuY29tPgogCiAgICAgICAgIFdlYkFzc2VtYmx5OiBhZGQgc3VwcG9y dCBmb3Igc3RyZWFtIEFQSXMgLSBKYXZhU2NyaXB0IEFQSQpkaWZmIC0tZ2l0IGEvU291cmNlL1dl YktpdC9OZXR3b3JrUHJvY2Vzcy93ZWJydGMvTmV0d29ya1JUQ1Jlc29sdmVyQ29jb2EuY3BwIGIv U291cmNlL1dlYktpdC9OZXR3b3JrUHJvY2Vzcy93ZWJydGMvTmV0d29ya1JUQ1Jlc29sdmVyQ29j b2EuY3BwCmluZGV4IDQ5NGRhZTQ0NmQ5YzUyYjE4Mjc1ODg4ZWE3Y2VjY2MyNDU2MjVlOWQuLjVm OWI5ZGZiYTIzNDM2ZTQ0NDM2MmU4MzRkMGVkNjcyZmE5MDQ3OTYgMTAwNjQ0Ci0tLSBhL1NvdXJj ZS9XZWJLaXQvTmV0d29ya1Byb2Nlc3Mvd2VicnRjL05ldHdvcmtSVENSZXNvbHZlckNvY29hLmNw cAorKysgYi9Tb3VyY2UvV2ViS2l0L05ldHdvcmtQcm9jZXNzL3dlYnJ0Yy9OZXR3b3JrUlRDUmVz b2x2ZXJDb2NvYS5jcHAKQEAgLTU2LDcgKzU2LDEzIEBAIHN0YXRpYyB2b2lkIHJlc29sdmVkTmFt ZShDRkhvc3RSZWYgaG9zdFJlZiwgQ0ZIb3N0SW5mb1R5cGUgdHlwZUluZm8sIGNvbnN0IENGU3Ry CiAgICAgZm9yIChzaXplX3QgaW5kZXggPSAwOyBpbmRleCA8IGNvdW50OyArK2luZGV4KSB7CiAg ICAgICAgIENGRGF0YVJlZiBkYXRhID0gKENGRGF0YVJlZilDRkFycmF5R2V0VmFsdWVBdEluZGV4 KHJlc29sdmVkQWRkcmVzc2VzLCBpbmRleCk7CiAgICAgICAgIGF1dG8qIGFkZHJlc3MgPSByZWlu dGVycHJldF9jYXN0PGNvbnN0IHN0cnVjdCBzb2NrYWRkcl9pbio+KENGRGF0YUdldEJ5dGVQdHIo ZGF0YSkpOwotICAgICAgICBhZGRyZXNzZXMudW5jaGVja2VkQXBwZW5kKFdlYkNvcmU6OklQQWRk cmVzcygqYWRkcmVzcykpOworICAgICAgICBpZiAoYWRkcmVzcy0+c2luX2ZhbWlseSA9PSBBRl9J TkVUKQorICAgICAgICAgICAgYWRkcmVzc2VzLnVuY2hlY2tlZEFwcGVuZChXZWJDb3JlOjpJUEFk ZHJlc3MoKmFkZHJlc3MpKTsKKyAgICAgICAgLy8gRklYTUU6IFdlIHNob3VsZCBwcm9iYWJseSBy ZXR1cm4gQUZfSU5FVDYgYWRkcmVzc2VzIGFzIHdlbGwuCisgICAgfQorICAgIGlmIChhZGRyZXNz ZXMuaXNFbXB0eSgpKSB7CisgICAgICAgIHJlc29sdmVyLT5jb21wbGV0ZWQobWFrZVVuZXhwZWN0 ZWQoV2ViQ29yZTo6RE5TRXJyb3I6OkNhbm5vdFJlc29sdmUpKTsKKyAgICAgICAgcmV0dXJuOwog ICAgIH0KICAgICByZXNvbHZlci0+Y29tcGxldGVkKFdURk1vdmUoYWRkcmVzc2VzKSk7CiB9Cg==
