* Change unp_scan() and its callbacks to pass the array of struct file **guenther2015-07-181-2/+2
| | | | | | | | and a count instead of calling the callback on each one, while also renders the 'dispose' argument superfluous. Move unp_*() prototypes from <sys/un.h> to <sys/unpcb.h> ok claudio@ mpi@
* Set POLLHUP even if no valid events were specified as per POSIX.millert2015-05-101-5/+5
| | | | | | | | Since we use the poll backend for select(2), care must be taken not to set the fd's bit in writefds in this case. A kernel-only flag, POLLNOHUP, is used by selscan() to tell the poll backend not to return POLLHUP on EOF. This is currently only used by fifo_poll(). The fifofs regress now passes. OK guenther@
* Now that we have a_fflag in struct vop_poll_args we can handlemillert2015-05-051-13/+34
| | | | | | | | things like POLLOUT on a read-only fd more sensibly. Previously, any poll events could be used regardless of the actual file flags of the descriptor. The new fifo_poll() is effectively a pared down soo_poll() with slightly different semantics to batter match FIFOs. OK and feedback from guenther@

* Instead of trying to emulate select/poll semantics with respect to EOFmillert2014-10-091-16/+10
| | | | | | | | | | by mutating so_state before calling soo_poll(), call soo_poll() normally but avoid setting SS_CANTRCVMORE in the reader's so_state on first open. This fixes EOF detection in select/poll on the reader side when the write side is closed. Also set SS_ISDISCONNECTED when the writer count reaches zero so POLLHUP is set in revents. Unlike Unix domain sockets, we need to clear the EOF indicator after it has been read so that subsequent reads will block waiting for a new writer. This now passes regress.

* Include <sys/vmmeter.h> directly instead of relying on it beingmpi2014-05-061-6/+3
| | | | | | | | | | | | | | pulled by <uvm/uvm_extern.h> and turn uvm_total() into a private function. The preferred way to get memory stats is through the VM_UVMEXP sysctl(3) since VM_METER is just a wrapper on top of it. In the kernel, use `uvmexp' directly instead of uvm_total(). This change does not remove <sys/vmmeter.h> from <uvm/uvm_extern.h> to give some more time to port maintainers to fix their ports. ok guenther@ as part of a larger diff.

* Unset fuse_mnt in fusefs_unmount after vflushing and freeing fbufs in use.pelikan2013-12-103-10/+10
| | | | | | | | This way, if fuse unmounts a FS without FBT_DESTROY, the fuse_mnt pointer is already invalidated. Also, on weird unmount situations with vnodes in use, vflush() them before doing fuse_device_cleanup(). Tested with ntfs-3g, ok syl@.
