fifo_kqfilter() VOP implementations, since they in theory are used only on open file descriptors, in which case the ioctls are via fifo_ioctl_f() and kqueue requests are via fifo_kqfilter_f(). Generate warnings if they are entered for now. These printf() calls should become panic() calls. Annotate and re-implement fifo_ioctl_f(): don't arbitrarily forward ioctls to the socket layer, only forward the ones we explicitly support for fifos. In the case of FIONREAD, don't forward the request to the write socket on a read-write fifo, or the read result is overwritten. Annotate a nasty case for the undefined POSIX O_RDWR on fifos, in which failure of the second ioctl will result in the socket pair being in an inconsistent state. Assert copyright as I find myself rewriting non-trivial parts of fifofs. MFC after: 3 days |
