What I used to do was to go to https://groups.google.com/g/syzkaller-bugs and then enter into the Google Groups searech box: Reported-by: syzbot+726dc8c62c3536431ceb@xxxxxxxxxxxxxxxxxxxxxxxxx which is a ***super*** clunky way to get to the syzkaller page. What would be nice is if there was an easy way that didn't rely on kernel developers knowing the internal URL structure of Syzbot to be able to enter the Reported-by link on some convenient web page, perhaps in a search box found in the front page of https://syzkaller.appspot.com, and be able to find the syzbot report web page that way. Since that doesn't exist today, I include both the Reported-by: and Link: in my commit descriptions, out of consideration to the reviewer who might want to be able to find the Syzbot page and don't know the secret trick to calculate the URL from the Reported-by: e-mail address. Another gotcha with Syzbot is that there are two id's, the "extid" and the "id" which makes thing ***super*** confusing. For example, both of these URL's go the same Syzbot report: https://syzkaller.appspot.com/bug?extid=726dc8c62c3536431ceb https://syzkaller.appspot.com/bug?id=eec08eb3763c9ec749fd565e70cfe6e485af7ed7 The Reported-by e-mail address uses the extid. So for example, this case, it would be syzbot+726dc8c62c3536431ceb@xxxxxxxxxxxxxxxxxxxxxxxxx. However, all of the links in the Syzbot web pages use the id form of the URL. So if you were browsing the syzbot reports assigned to the crypto subsystem via https://syzkaller.appspot.com/upstream/s/crypto, you would find the id-style link, and then the commit fixing the bug might have something like this: Reported-by: syzbot+726dc8c62c3536431ceb@xxxxxxxxxxxxxxxxxxxxxxxxx Link: https://syzkaller.appspot.com/bug?id=eec08eb3763c9ec749fd565e70cfe6e485af7ed7 In that case, there is no (obvious) relationship between the hex string found in the Reported-by line and the Link line. One additional unfortunate fallout from syzbot having an "extid" and "id", is that depending on how the syzbot entry initially found by the contributor sending in a patch to address a syzbot report, either URL can be found in mailing list archives. So if you search for "extid=726dc8c62c3536431ceb" you won't find references to "id=eec08eb3763c9ec749fd565e70cfe6e485af7ed7" even though they are both referring to same Syzbot report. <<< sigh >>>> As they say, the hardest problem to solve in the C.S. world is naming, and syzbot has two names for every single syzbot report, and both are exposed to the poor user. :-( - Ted
