* Change the second argument of vflush() to an integer that specifiesIan Dowse2001-05-161-12/+4
| | | | | | | | | | | | | | | | | | | | | | | the number of references on the filesystem root vnode to be both expected and released. Many filesystems hold an extra reference on the filesystem root vnode, which must be accounted for when determining if the filesystem is busy and then released if it isn't busy. The old `skipvp' approach required individual filesystem xxx_unmount functions to re-implement much of vflush()'s logic to deal with the root vnode. All 9 filesystems that hold an extra reference on the root vnode got the logic wrong in the case of forced unmounts, so `umount -f' would always fail if there were any extra root vnode references. Fix this issue centrally in vflush(), now that we can. This commit also fixes a vnode reference leak in devfs, which could result in idle devfs filesystems that refuse to unmount.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An initial tidyup of the mount() syscall and VFS mount code. This code replaces the earlier work done by jlemon in an attempt to make linux_mount() work. * the guts of the mount work has been moved into vfs_mount(). * move `type', `path' and `flags' from being userland variables into being kernel variables in vfs_mount(). `data' remains a pointer into userspace. * Attempt to verify the `type' and `path' strings passed to vfs_mount() aren't too long. * rework mount() and linux_mount() to take the userland parameters (besides data, as mentioned) and pass kernel variables to vfs_mount(). (linux_mount() already did this, I've just tidied it up a little more.) * remove the copyin*() stuff for `path'. `data' still requires copyin*() since its a pointer into userland. * set `mount->mnt_statf_mntonname' in vfs_mount() rather than in each filesystem. This variable is generally initialised with `path', and each filesystem can override it if they want to. * NOTE: f_mntonname is intiailised with "/" in the case of a root mount.

* Add snapshots to the fast filesystem. Most of the changes supportKirk McKusick2000-07-111-2/+7
| | | | | | | | | | | | | | | | | | | | | | | the gating of system calls that cause modifications to the underlying filesystem. The gating can be enabled by any filesystem that needs to consistently suspend operations by adding the vop_stdgetwritemount to their set of vnops. Once gating is enabled, the function vfs_write_suspend stops all new write operations to a filesystem, allows any filesystem modifying system calls already in progress to complete, then sync's the filesystem to disk and returns. The function vfs_write_resume allows the suspended write operations to begin again. Gating is not added by default for all filesystems as for SMP systems it adds two extra locks to such critical kernel paths as the write system call. Thus, gating should only be added as needed. Details on the use and current status of snapshots in FFS can be found in /sys/ufs/ffs/README.snapshot so for brevity and timelyness is not included here. Unless and until you create a snapshot file, these changes should have no effect on your system (famous last words). Notes: svn path=/head/; revision=62976

More specific items of this patch: o Removed support for symbolic links, and the need for fdesc_readlink(). o Put all the code from fdesc_attr() into fdesc_getattr() and removed fdesc_attr(). This also made it easier to properly give all nodes unique inode numbers. o The removal of all non-fd nodes allowed the removal of the fdesc_read(), fdesc_write(), and fdesc_ioctl() nodes, since we no longer have nodes that get special handling. o Correct the component name validity-checking in fdesc_lookup(). It previously detected the end of the string by checking for a terminating NUL, now it uses cnp->cn_namelen. o Handle kqueue files as FIFOs. This is probably the closest file type to represent this type of file there is, and it is unfortunately not very representative of a kqueue. Creation time is not supported by kqueue, so ctime, mtime and atime are all set to the current time when getattr() was called. o Also set st_[mca]time to the current time since there's no data in socket structures that can be used to fill this in (FIFOs). o Simplify fdesc_readdir() since it only has to report the numbered fd nodes. Add `.' and `..' directory links as well. o Remove read bits from directories as they tend to confuse programs like tar(1).

This is initially only for file systems that implement the following ops that do a WILLRELE: vop_create, vop_whiteout, vop_mknod, vop_remove, vop_link, vop_rename, vop_mkdir, vop_rmdir, vop_symlink This is initial DNA that doesn't do anything yet. VFS_VRELE is implemented but not called. A default vfs_vrele was created for fs implementations that use the standard vnode management routines. VFS_VRELE implementations were made for the following file systems: Standard (vfs_vrele) ffs mfs nfs msdosfs devfs ext2fs Custom union umapfs Just EOPNOTSUPP fdesc procfs kernfs portal cd9660 These implementations may change as VOP changes are implemented. In the next phase, in the vop implementations calls to vrele and the vrele part of vput will be moved to the top layer vfs_vnops and made visible to all layers. vput will be replaced by unlock in these cases. Unlocking will still be done in the per fs layer but the refcount decrement will be triggered at the top because it doesn't hurt to hold a vnode reference a little longer. This will have minimal impact on the structure of the existing code. This will only be done for vnode arguments that are released by the various fs vop implementations. Wider use of VFS_VRELE will likely require restructuring of the code. Reviewed by: phk, dyson, terry et. al. Submitted by: Michael Hancock <michaelh@cet.co.jp> Notes: svn path=/head/; revision=33964
