CVE-2022-49767

CVE-2022-49767 affects the Linux kernel 9p/trans_fd path. The issue arises because p9_mux_poll_stop() could fail to interrupt blocking kernel_read()/kernel_write() on pipes due to fd_open() not setting O_NONBLOCK, whereas socket paths already use O_NONBLOCK. A minimal patch makes O_NONBLOCK alway...

A failed upgrade may lead to hung goroutines

Impact Processes using tableflip may encounter hung goroutines in the parent process, after a failed upgrade. The Go runtime has annoying behaviour around setting and clearing ONONBLOCK: exec.Cmd.Start ends up calling os.File.Fd for any file in exec.Cmd.ExtraFiles. os.File.Fd disables both the us...
