Of the currently open syzbot reports against the upstream kernel, I've manually marked 18 of them as possibly being bugs in the "fs/9p" 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 18 bugs, 3 were seen in mainline in the last week. If you believe a bug is no longer valid, please close the syzbot report by sending a '#syz fix', '#syz dup', or '#syz invalid' command in reply to the original thread, as explained at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 "fs/9p" subsystem, please let me know, and if possible forward the report to the correct people or mailing list. Here are the bugs: -------------------------------------------------------------------------------- Title: KASAN: use-after-free Read in __queue_work (2) Last occurred: 4 days ago Reported: 358 days ago Branches: Mainline and others Dashboard link: https://syzkaller.appspot.com/bug?id=c14270323f22e896228f470164aac59114d388be Original thread: https://lkml.kernel.org/lkml/000000000000f665a30570885...@google.com/T/#u This bug has a C reproducer.
