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 2 of them as possibly being bugs in the vhost 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 2 bugs, 1 was 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 If you believe a bug is no longer valid, please close the syzbot report by sending a '#syz fix', '#syz dup', or '#syz invalid' command in reply to the original thread, as explained at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 vhost subsystem, please let me know, and if possible forward the report to the correct people or mailing list. Here are the bugs: -------------------------------------------------------------------------------- Title: memory leak in vhost_net_ioctl Last occurred: 0 days ago Reported: 26 days ago Branches: Mainline Dashboard link: https://syzkaller.appspot.com/bug?id=12ba349d7e26ccfe95317bc376e812ebbae2ee0f Original thread: https://lkml.kernel.org/lkml/000000000000188da1058a9c25e3@xxxxxxxxxx/T/#u This bug has a C reproducer.
