* Fix fuse node lookups. Currently fusefs nodes in the kernel remember thenatano2016-09-074-53/+40
| | | | | | | | | | | | | | | | | | | | parent inode number for ".." lookups. This only works until the kernel starts to reuse vnodes and the parent's vnode is reclaimed and the ino to path mapping is removed from the userland process by libfuse. Fix this by using reference counting in libfuse, so that parent mapping are retained as long as a child uses them. Also, don't free the root node. This commit resolves following issue: $ doas fuse-zip ~/Downloads/foo.zip /mnt $ ls /mnt openbsd-www $ grep -IR foo /usr/src > /dev/null # force vfs to reclaim vnodes $ ls /mnt ls: /mnt: No such file or directory $ ok tedu

| | | | | | | | | vattr in userspace is suboptimal as some related helpers are not available, e.g. VATTR_NULL() and IFTOVT(). The conversion is now done in the kernel where it belongs. As a side effect the <sys/vnode.h> include can be removed from libfuse. tweaks and ok guenther

* Neuter fuse_vptofh() and fuse_fhtovp(). I implemented those functionsnatano2016-08-151-18/+3
| | | | | | | | | | | | under the assumption, that fuse_vget() has reasonable semantics, while this is not the case. fusefs_vget() only functions correctly, if the file in questions has recently been accessed and is still in the vnode cache of the userspace daemon associated with the mount point. As a matter of fact the fuse api doesn't feature a reasonable way to map inode numbers to a handle at all (see struct fuse_operations). ok guenther

| | | | | | | | | | | vtype in struct fusefs_node and v_type in struct vnode. Given the fact, that fusefs_node structs are never allocated without an associated vnode and those two fields are always in sync, one of those locations is superfluous. While there remove the unused nlookup field. ok mpi

| | | | | | | | | | 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
* When pulling and unmounting an umass USB stick, the file systembluhm2016-03-271-2/+2
| | | | | | | | | | | | 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@

* 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@

| | | | | | | | 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.
