Christoph Hellwig e0c47a51fc net/9p: validate fds in p9_fd_open ... [ Upstream commit a39c46067c ] p9_fd_open just fgets file descriptors passed in from userspace, but doesn't verify that they are valid for read or writing. This gets cought down in the VFS when actually attempting a read or write, but a new warning added in linux-next upsets syzcaller. Fix this by just verifying the fds early on.
