[This email was generated by a script. Let me know if you have any suggestions

Of the currently open syzbot reports against the upstream kernel, I've manually
marked 17 of them as possibly being bugs in the "net/tls" subsystem. I've
listed these reports below, sorted by an algorithm that tries to list first the
reports most likely to be still valid, important, and actionable.
Of these 17 bugs, 7 were seen in mainline in the last week.
Of these 17 bugs, 6 were bisected to commits from the following people:
Dave Watson <[email protected]>
Vakul Garg <[email protected]>
Boris Pismenny <[email protected]>
Daniel Borkmann <[email protected]>
If you believe a bug is no longer valid, please close the syzbot report by
sending a '#syz fix', '#syz dup', or '#syz invalid' command in reply to the
original thread, as explained at https://goo.gl/tpsmEJ#status
If you believe I misattributed a bug to the "net/tls" subsystem, please let me
know, and if possible forward the report to the correct people or mailing list.
Here are the bugs:
