Currently there is no way to tell if write operation invoked via vn_start_write() on the given vnode will be successful. VOP_LEASE() may help to solve this problem, but its return value ignored nearly everywhere. For now just assume that the missing upper layer on write means insufficient access rights (which is correct for most cases).

Add snapshots to the fast filesystem. Most of the changes support 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).

Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new field in struct buf: b_iocmd. The b_iocmd is enforced to have exactly one bit set. B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes. Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL. Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading. This change is a step in the direction towards a stackable BIO capability. A lot of this patch were machine generated (Thanks to style(9) compliance!) Vinum users: Greg has not had time to test this yet, be careful.

the #defines for the vm_inherit_t and vm_prot_t types next to their

useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE}

Make sure file after VOP_OPEN is VMIO'd when transfering control from

for reading.
Fix bug in union_lookup() (note: there are probably still several bugs
in union_lookup()). This one set lerror as a side effect without
setting lowervp, causing copyup code further on down to crash on a null
lowervp pointer. Changed the side effect to use a temporary variable
instead.

This is a major fixup of unionfs. At least 30 serious bugs have been
fixed (many due to changing semantics in other parts of the kernel and not
the original author's fault), including one critical one: unionfs could
cause UFS corruption in the fronting store due to calling VOP_OPEN for
writing without turning on vmio for the UFS vnode.
Most of the bugs were related to semantics changes in VOP calls, lock
ordering problems (causing deadlocks), improper handling of a read-only
backing store (such as an NFS mount), improper referencing and locking
of vnodes, not using real struct locks for vnode locking, not using
recursive locks when accessing the fronting store, and things like that.
New functionality has been added: unionfs now has mmap() support, but
only partially tested, and rename has been enhanced considerably.
There are still some things that unionfs cannot do. You cannot
rename a directory without confusing unionfs, and there are issues
with softlinks, hardlinks, and special files. unionfs mostly doesn't
understand them (and never did).
There are probably still panic situations, but hopefully no where near
as many as before this commit.
The unionfs in this commit has been tested overlayed on /usr/src
(backing /usr/src being a read-only NFS mount, fronting /usr/src being
a local filesystem). kernel builds have been tested, buildworld is
undergoing testing. More testing is necessary.

In the words of the submitter: --------- Make callers of namei() responsible for releasing references or locks instead of having the underlying filesystems do it. This eliminates redundancy in all terminal filesystems and makes it possible for stacked transport layers such as umapfs or nullfs to operate correctly. Quality testing was done with testvn, and lat_fs from the lmbench suite. Some NFS client testing courtesy of Patrik Kudo. vop_mknod and vop_symlink still release the returned vpp. vop_rename still releases 4 vnode arguments before it returns. These remaining cases will be corrected in the next set of patches. --------- Submitted by: Michael Hancock <michaelh@cet.co.jp>

1. Remove VOP_UPDATE, it is (also) an UFS/{FFS,LFS,EXT2FS,MFS}
intereface function, and now lives in the ufsmount structure.
2. Remove VOP_SEEK, it was unused.
3. Add mode default vops:
VOP_ADVLOCK vop_einval
VOP_CLOSE vop_null
VOP_FSYNC vop_null
VOP_IOCTL vop_enotty
VOP_MMAP vop_einval
VOP_OPEN vop_null
VOP_PATHCONF vop_einval
VOP_READLINK vop_einval
VOP_REALLOCBLKS vop_eopnotsupp
And remove identical functionality from filesystems
4. Add vop_stdpathconf, which returns the canonical stuff. Use
it in the filesystems. (XXX: It's probably wrong that specfs
and fifofs sets this vop, shouldn't it come from the "host"
filesystem, for instance ufs or cd9660 ?)
5. Try to make system wide VOP functions have vop_* names.
6. Initialize the um_* vectors in LFS.
(Recompile your LKMS!!!)

Revised fix for locking violation when unionfs calls vput with UN_KLOCK flag. When UN_KLOCK is set, VOP_UNLOCK should keep uppervp locked and clear UN_ULOCK flag. To do this, when UN_KLOCK is set, (1) union_unlock clears UN_ULOCK and does not clear UN_KLOCK, (2) union_lock() does not access uppervp and does not clear UN_KLOCK, and (3) callers of vput/VOP_UNLOCK should clear UN_KLOCK. For example, vput becomes: SETKLOCK(union_node); vput(vnode); CLEARKLOCK(union_node); where SETKLOCK macro sets UN_KLOCK and CLEARKLOCK macro clears UN_KLOCK.

Do not clear UN_ULOCK in certain case. Our vput calls vm_object_deallocate() --> vm_object_terminate(). The vm_object_terminate() calls vn_lock(), since UN_LOCKED has been already cleared in union_unlock(). Then, union_lock locks upper vnode when UN_ULOCK is not set. The upper vnode is not unlocked when UN_KLOCK is set in union_unlock(), thus, union_lock tries to lock locked vnode and we get panic.

Dirty change in union_lock(). Sometimes upper vnode is locked without UN_ULOCK flag. This shows a locking violation but I couldn't find the reason UN_ULOCK is not set or upper vnode is not unlocked. I added the code that detect this case and adjust un_flags. DIAGNOSTIC kernel doesn't adjust un_flags, but just panic here to help debug by kernel hackers.

Quick-hack to avoid `lock against myself' panic. It is not the real fix! The ufs_link() assumes that vnode is not unlocked and tries to lock it in certain case. Because union_link calls VOP_LINK after locking vnode, vn_lock in ufs_link causes above panic. Currently, I don't know the real fix for a locking violation in union_link, but I think it is important to avoid panic. A vnode is unlocked before calling VOP_LINK and is locked after it if the vnode is not union fs. Even though panic went away, the process that access the union fs in which link was made will hang-up. Hang-up can be easily reproduced by following operation: mount -t union a b cd b ln foo bar ls

The function union_fsync tries to lock overlaying vnode object when dolock is not set (that is, targetvp == overlaying vnode object). Current code use FIXUP macro to do this, and never unlocks overlaying vnode object in union_fsync. So, the vnode object will be locked twice and never unlocked. PR: 3271 Submitted by: kato

Introduced a type `vop_t' for vnode operation functions and used it 1138 times (:-() in casts and a few more times in declarations. This change is null for the i386. The type has to be `typedef int vop_t(void *)' and not `typedef int vop_t()' because `gcc -Wstrict-prototypes' warns about the latter. Since vnode op functions are called with args of different (struct pointer) types, neither of these function types is any use for type checking of the arg, so it would be preferable not to use the complete function type, especially since using the complete type requires adding 1138 casts to avoid compiler warnings and another 40+ casts to reverse the function pointer conversions before calling the functions.

From tim@cs.city.ac.uk (Tim Wilkinson): Find enclosed a short bugfix to get the union filesystem up and running in FreeBSD-current. We don't think we've got all the problems yet but these fixes sort out the major ones (which mostly concert bad locking of vnodes), no doubt we'll post others as necessary. Known problems include the inability of the umount command (not the system call) to unmount unions in certain circumstances (this is due the way "realpath" works), and the failure of direntries to always get all available files in unioned subdirectories. We are, as they say, working on it. Submitted by: tim@cs.city.ac.uk (Tim Wilkinson)
