[This email was generated by a script. 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 distinct crashes that syzbot has seen in the last week, I've manually marked 8 of them as possibly being bugs in the "net/bpf" subsystem. I've listed these bug reports below. Of these 8 reports, 1 was bisected to a commit from the following person: Alexei Starovoitov <ast@xxxxxxxxxx> I've manually checked that this bisection result looks plausible. If you believe a bug report is no longer valid, please close it by sending a '#syz fix', '#syz dup', or '#syz invalid' command in reply to the original thread, as explained at https://goo.gl/tpsmEJ#status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 report to the "net/bpf" subsystem, please let me know and (if possible) forward it to the correct place. Note: in total, I've actually assigned 42 open syzbot reports to this subsystem. But to help focus people's efforts, I've only listed the 8 that have (re-)occurred in the last week. Let me know if you want the full list.
