Let me know if you have any suggestions to make it better, or if you want it re-generated with the latest status.] Of the currently open syzbot reports against the upstream kernel, I've manually marked 14 of them as possibly being bugs in the "net/tipc" 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, 2 were seen in mainline in the last week. Of these 14 bugs, 8 were bisected to commits from the following people: Jon Maloy Junwei Hu If you believe a bug is no longer valid, please close the syzbot report by sending a '#syz fix', '#syz dup', or '#syz invalid' command in reply to the original thread, as explained at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/tipc" subsystem, please let me know, and if possible forward the report to the correct people or mailing list.
