Of the currently open syzbot reports against the upstream kernel, I've manually
marked 13 of them as possibly being bugs in the "net/netrom" 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 13 bugs, 8 were seen in mainline in the last week.
Of these 13 bugs, 4 were bisected to commits from the following person:
Cong Wang <xiyou.wangc...@gmail.com>
If you believe a bug is no longer valid, please close the syzbot report by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/netrom" subsystem, please let
me know, and if possible forward the report to the correct people or mailing
list.
Here are the bugs:
