2016-05-26The doforce variable isn't modified anywhere. Also, the only filesystemMartin Natano
left using it is fuse. It has been removed from all other filesystems. ok millert deraadt
2016-04-26Populate all necessary statfs members in .vfs_statfs. cd9660, udf,Martin Natano
msdosfs and nfsv2 don't set f_namemax. ntfs and ext2fs don't set f_namemeax and f_favail. fusefs doesn't set f_mntfromspec, f_favail and f_iosize. Also, make all filesystems use copy_statfs_info(), so that all statfs information is filled in correctly for the (sb != &mp->mnt-stat) case. ok stefan
2016-03-27When pulling and unmounting an umass USB stick, the file systemAlexander Bluhm
could end up in an inconsistent state. The fstype dependent mp->mnt_data was NULL, but the general mp was still listed as a valid mount point. Next access to the file system would crash with a NULL pointer dereference. If closing the device fails, the mount point must go away anyway. There is nothing we can do about it. Remove the workaround for the EIO error in the general unmount code, but do not generate any error in the file system specific unmount functions. OK natano@ beck@

2016-02-25Replace a usage of ROOTINO ((ufsino_t)2 with FUSE_ROOTINO ((ino_t)1).natano
The FUSE_ROOTINO define is used everywhere else in fuse, so the mismatch caused a file handle for the filesystem root to be falsely rejected with ESTALE. ok stefan@

2015-07-18Change unp_scan() and its callbacks to pass the array of struct file **Philip Guenther
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@
2015-05-10Set POLLHUP even if no valid events were specified as per POSIX.Todd C. Miller
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@
2015-05-05Now that we have a_fflag in struct vop_poll_args we can handleTodd C. Miller
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@
2015-04-17Tweaks utimensat/futimens handling to always update ctime, even when bothPhilip Guenther
atime and mtime are UTIME_OMIT (at least for ufs, tmpfs, and ext2fs), and to correctly handle a timestamp of -1. ok millert@

2015-02-10First step towards making uiomove() take a size_t size argument:Miod Vallat
- rename uiomove() to uiomovei() and update all its users. - introduce uiomove(), which is similar to uiomovei() but with a size_t. - rewrite uiomovei() as an uiomove() wrapper. ok kettenis@

2014-12-16primary change: move uvm_vnode out of vnode, keeping only a pointer.Ted Unangst
objective: vnode.h doesn't include uvm_extern.h anymore. followup changes: include uvm_extern.h or lock.h where necessary. ok and help from deraadt
2014-12-03use arc4random_buf() instead of (r << 32) | r; discussed with matthewTheo de Raadt
2014-11-18move arc4random prototype to systm.h. more appropriate for most codeTed Unangst
to include that than rdnvar.h. ok deraadt dlg
2014-11-03include sys/unistd.h where needed instead of indirect reliance. ok jsgTed Unangst
2014-10-09Instead of trying to emulate select/poll semantics with respect to EOFTodd C. Miller
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.

PS_{ZOMBIE,EMBRYO} on the process instead of peeking into the process's thread data. This eliminates the need for the thread-level SDEAD state.

2014-05-06Include <sys/vmmeter.h> directly instead of relying on it beingMartin Pieuchot
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.
