ad | Merge the remaining changes from the ad-namecache branch, affecting namei() and getcwd():
- push vnode locking back as far as possible. - do most lookups directly in the namecache, avoiding vnode locks & refs. - don't block new refs to vnodes across VOP_INACTIVE(). - get shared locks for VOP_LOOKUP() if the file system supports it. - correct lock types for VOP_ACCESS() / VOP_GETATTR() in a few places.
Possible future enhancements:
- make the lookups lockless. - support dotdot lookups by being lockless and inferring absence of chroot. - maybe make it work for layered file systems. - avoid vnode references at the root & cwd.

hannken | Remove the hints "isodir" and "relocated" from cd9660_vget_internal() and always reread the directory entry by inumber. For directories the directory entry is always its "." entry.
Always read directories via the device vnode to prevent buffer cache inconsistency. Keep i_devvp as a hint for fstat(1) and friends and always use im_devvp for reads. No need to vref()/vrele() i_devvp.
The additional bread is either cached because cd9660_lookup() just released the buffer or will be used in the near future when the directory gets traversed during lookup.

mlelstv | branches: 1.70.2; 1.70.4; Drop two uses of disk label data.
msdosfs and cd9660 are the only filesystems that verify the filesystem type in the label. This is the wrong place, sanity checks should only rely on the inner structure of the filesystem (like signatures or magic numbers).
msdosfs also used the device type information from the label to deduce a filesystem parameter heuristically for the gemdos variant. If there is no information inside the filesystem data itself, this should be an explicit mount option.

ad | branches: 1.61.2; PR kern/38141 lookup/vfs_busy acquire rwlock recursively
Simplify the mount locking. Remove all the crud to deal with recursion on the mount lock, and crud to deal with unmount as another weirdo lock.
Hopefully this will once and for all fix the deadlocks with this. With this commit there are two locks on each mount:
- krwlock_t mnt_unmounting. This is used to prevent unmount across critical sections like getnewvnode(). It's only ever read locked with rw_tryenter(), and is only ever write locked in dounmount(). A write hold can't be taken on this lock if the current LWP could hold a vnode lock.
- kmutex_t mnt_updating. This is taken by threads updating the mount, for example when going r/o -> r/w, and is only present to serialize updates. In order to take this lock, a read hold must first be taken on mnt_unmounting, and the two need to be held across the operation.
One effect of this change: previously if an unmount failed, we would make a half hearted attempt to back out of it gracefully, but that was unlikely to work in a lot of cases. Now while an unmount that will be aborted is in progress, new file operations within the mount will fail instead of being delayed. That is unlikely to be a problem though, because if the admin requests unmount of a file system then s(he) has made a decision to deny access to the resource.

jmmv | Apply the NFS exports list rototill patch:
- Remove all NFS related stuff from file system specific code. - Drop the vfs_checkexp hook and generalize it in the new nfs_check_export function, thus removing redundancy from all file systems. - Move all NFS export-related stuff from kern/vfs_subr.c to the new file sys/nfs/nfs_export.c. The former was becoming large and its code is always compiled, regardless of the build options. Using the latter, the code is only compiled in when NFSSERVER is enabled. While doing this, also make some functions in nfs_subs.c conditional to NFSSERVER. - Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a path and a set of export entries. At the moment it can only clear the exports list or append entries, one by one, but it is done in a way that allows setting the whole set of entries atomically in the future (see the comment in mountd_set_exports_list or in doc/TODO). - Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so that it becomes file system agnostic. In fact, all this whole thing was done to remove a 'XXX' block from this utility! - Change the mount*, newfs and fsck* userland utilities to not deal with NFS exports initialization; done internally by the kernel when initializing the NFS support for each file system. - Implement an interface for VFS (called VFS hooks) so that several kernel subsystems can run arbitrary code upon receipt of specific VFS events. At the moment, this only provides support for unmount and is used to destroy NFS exports lists from the file systems being unmounted, though it has room for extension.

thorpej | - Define a VFS_ATTACH() macro that places a reference to a vfsops structure into the "vfsops" link set. - Use VFS_ATTACH() where vfsops are declared for individual file systems. - In vfsinit(), traverse the "vfsops" link set, rather than vfs_list_initial[].

mycroft | Fixing age old cruft: * Rather than using mnt_maxsymlinklen to indicate that a file systems returns d_type fields(!), add a new internal flag, IMNT_DTYPE.
Add 3 new elements to ufsmount: * um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed in the first place). * um_dirblksiz, which tracks the current directory block size, eliminating the FS-specific checks littered throughout the code. This may be used later to make the block size variable. * um_maxfilesize, which is the maximum file size, possibly adjusted lower due to implementation issues.
Sync some bug fixes from FFS into ext2fs, particularly: * ffs_lookup.c 1.21, 1.28, 1.33, 1.48 * ffs_inode.c 1.43, 1.44, 1.45, 1.66, 1.67 * ffs_vnops.c 1.84, 1.85, 1.86

hannken | Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.
- Not enabled by default. Needs kernel option FFS_SNAPSHOT. - Change parameters of ffs_blkfree. - Let the copy-on-write functions return an error so spec_strategy may fail if the copy-on-write fails. - Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock. - Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer. - Add a function ffs_checkfreefile needed for snapshot creation. - Add special handling of snapshot files: Snapshots may not be opened for writing and the attributes are read-only. Use the mtime as the time this snapshot was taken. Deny mtime updates for snapshot files. - Add function transferlockers to transfer any waiting processes from one lock to another. - Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through a vnode. - Add snapshot support to ls, fsck_ffs and dump.

jrf | First pass for some caddr_t removal and changes to get rid of it where we no longer use and/or need it
- removed casts from unionfs, deadfs and fdesc (there are more to hunt down still) - changed vfs_quotactl args argumet from caddr_t to void * - changed vfs_quotactl structures/callers to reflect the api change
Compiled fine and ran for about a day. Approved/reviewed by christos@netbsd.org and gimpy@netbsd.org.

atatat | Dynamic sysctl.
Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(), vfs_sysctl(), etc, routines, along with sysctl_int() et al. Now all nodes are registered with the tree, and nodes can be added (or removed) easily, and I/O to and from the tree is handled generically.
Since the nodes are registered with the tree, the mapping from name to number (and back again) can now be discovered, instead of having to be hard coded. Adding new nodes to the tree is likewise much simpler -- the new infrastructure handles almost all the work for simple types, and just about anything else can be done with a small helper function.
All existing nodes are where they were before (numerically speaking), so all existing consumers of sysctl information should notice no difference.
PS - I'm sorry, but there's a distinct lack of documentation at the moment. I'm working on sysctl(3/8/9) right now, and I promise to watch out for buses.

darrenr | Pass lwp pointers throughtout the kernel, as required, so that the lwpid can be inserted into ktrace records.

christos | PR/1796: John Kohl: statfs misbehaves under chrooted environments.
- Under chroot it displays only the visible filesystems with appropriate paths. - The statfs f_mntonname gets adjusted to contain the real path from root. - While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(), and factored out some of the vfsop statfs() code to copy_statfs_info(). This fixes the problem where some filesystems forgot to set fsid. - Made coda look more like a normal fs.

Due to missing checks in the mount syscall, and a wrong assumption on the file systems side, the kernel could allocate an unbounded or zero-sized memory buffer, and could dereference a NULL pointer when particular arguments are given by a user.

bouyer | branches: 1.63.6.1.2; 1.63.6.1.6; Pull up following revision(s) (requested by tsutsui in ticket #1115): sys/fs/cd9660/cd9660_vfsops.c: revision 1.68 Apply a similar fix for mount function from ffs_vfsops.c rev 1.186: Change cd9660_mount, in MNT_UPDATE case, to check dev_t's for equality instead of just vnode pointers. Fixes erroneous "Invalid argument" errors from mount(8) with -u against cd9660 root in the presence of mfs or tmpfs /dev prepared after initial mountroot. Tested on QEMU running cobalt Restore CD.

rmind | Implement sharing of vnode_t::v_interlock amongst vnodes: - Lock is shared amongst UVM objects using uvm_obj_setlock() or getnewvnode(). - Adjust vnode cache to handle unsharing, add VI_LOCKSHARE flag for that. - Use sharing in tmpfs and layerfs for underlying object. - Simplify locking in ubc_fault(). - Sprinkle some asserts.
Discussed with ad@.
