christos | Add ACL support for FFS. From FreeBSD.

hannken | Locking a layer vnode using the regular bypass routine is no longer
racy. Undo the change from 2017-03-30 11:16:52, commitid eurqbzuGxGRlryLz
and make vi_lock a krwlock_t again.

Locking a layer vnode is racy as it may become reclaimed before
calling the operation on the lower vnode.
Replace vi_lock with a rw_obj and change layered file systems
to share the lock with the lower vnode.
Layered file systems now use genfs_lock()/_unlock/_islocked().
Welcome to 7.99.67

| 27-Jan-2017 |
hannken | Handle v_writecount from layer_open(), layer_close() and layer_revoke()
so lower file system vnodes get marked as open for writing.

hannken | branches: 1.20.4;
The current implementation of vn_lock() is racy. Modification of
the vnode operations vector for active vnodes is unsafe because it
is not known whether deadfs or the original file system will be
called.
- Pass down LK_RETRY to the lock operation (hint for deadfs only).
- Change deadfs lock operation to return ENOENT if LK_RETRY is unset.
- Change all other lock operations to check for dead vnode once
the vnode is locked and unlock and return ENOENT in this case.
With these changes in place vnode lock operations will never succeed
after vclean() has marked the vnode as VI_XLOCK and before vclean()
has changed the operations vector.

hannken | branches: 1.19.2; 1.19.12; 1.19.16;
Change VOP_BWRITE() to take a vnode as its first argument like all other
VOPs do. Layered file systems no longer have to modify bp->b_vp and run
into trouble when an async VOP_BWRITE() uses the wrong vnode.
- change all occurences of VOP_BWRITE(bp) to VOP_BWRITE(bp->b_vp, bp).
- remove layer_bwrite().
- welcome to 5.99.55
Adresses PR kern/38762 panic: vwakeup: neg numoutput
No objections from tech-kern@.
|
| 1.18 |
| 10-Jan-2011 |
hannken | Add layer_revoke() that adjusts the lower vnode use count to be at least as
high as the upper vnode count before passing down the VOP_REVOKE().
This way vclean() check for active (vp->v_usecount > 1) vnodes gets it right.
Should fix PR kern/43456.
|
| 1.17 |
| 02-Jul-2010 |
hannken | LK_INTERLOCK is no longer a valid flag for VOP_LOCK(). This makes
layer_*lock*() obsolete. Remove them and handle lock operations
with the generic bypass function.
Ride 5.99.34.

|

| 28-May-2004 |
wrstuden | Since VOP_UPCALL() has been a long time in coming, add this partial
fix for layered-file-removal. It will work for the case of accessing
and deleting a file through the layered file system. Accessing via
the layer and deleting on the underlying still won't work, nor will
accessing via complicated structures (like two umap layers over a
given file systems).
We still need VOP_UPCALL(), but this is better than things were before.
This patch has been discussed off & on for a while. This incarnation
was tested by hannken at netbsd dot org.

| 25-Jan-2004 |
hannken | branches: 1.11.2;
Make VOP_STRATEGY(bp) a real VOP as discussed on tech-kern.
VOP_STRATEGY(bp) is replaced by one of two new functions:
- VOP_STRATEGY(vp, bp) Call the strategy routine of vp for bp.
- DEV_STRATEGY(bp) Call the d_strategy routine of bp->b_dev for bp.
DEV_STRATEGY(bp) is used only for block-to-block device situations.

state "VS_ACTIVE" to assert a loaded vnode with usecount > 0.
- Redo FSTRANS in vnode_if.c and use it for VOP_LOCK and VOP_UNLOCK.
- Cleanup the genfs lock operations.
- Make "struct vnode_impl" member "vi_lock" a krwlock_t again.
- Remove the lock type argument from fstrans_start and
fstrans_start_nowait,
remove now unused FSTRANS state "FSTRANS_SUSPENDING".
