Reminder: 14 open syzbot bugs in "net/sctp" subsystem
From: Eric Biggers
Date: Tue Jun 25 2019 - 01:49:36 EST
[This email was generated by a script. Let me know if you have any suggestions
to make it better.]
Of the currently open syzbot reports against the upstream kernel, I've manually
marked 14 of them as possibly being bugs in the "net/sctp" 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 14 bugs, 4 were seen in mainline in the last week.
Of these 14 bugs, 2 were bisected to commits from the following person:
Xin Long <lucien.xin@xxxxxxxxx>
If you believe a bug is no longer valid, please close the syzbot report by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/sctp" subsystem, please let me
know, and if possible forward the report to the correct people or mailing list.
Here are the bugs:
