hannken | Operation union_readdirhook() stores the lower directory as un_uppervp.
This breaks the assumption that un_uppervp->v_mount is the upper mount.
Fix by storing the directory as un_lowervp and adapt union_readdir().
Should fix PR kern/55552: panic with union mount

hannken | branches: 1.29.2; 1.29.10;
Make union_newlower() ans union_newupper() local to union_subr.c,
expand and remove union_updatevp() and take care to transfer the
vnode lock from the union vnode to its new upper vnode without
breaking the fstrans state.
Add assertions that un_lowervp and un_uppervp never change from
non-NULL to non-NULL.

hannken | branches: 1.28.10;
Change union to vcache. Use address of the union node as key.
It would be better to use (uppervp, lowervp) as key, but either
may be NULL and may change any time.

hannken | Add reference count to union node.

Member un_flags is unused now -- remove.
|
| 1.25 |
| 13-Feb-2014 |
hannken | Get rid of UN_KLOCK to keep a lock on vput(). It is not really needed
and makes the source difficult to read. Always hold references to the
union nodes until the operation is done.

dholland | branches: 1.24.2;
Disentangle the namecache from the internals of namei.
- Move the namecache's hash computation to inside the namecache code,
instead of being spread out all over the place. Remove cn_hash from
struct componentname and delete all uses of it.
- It is no longer necessary (if it ever was) for cache_lookup and
cache_lookup_raw to clear MAKEENTRY from cnp->cn_flags for the cases
that cache_enter already checks for.
- Rearrange the interface of cache_lookup (and cache_lookup_raw) to
make it somewhat simpler, to exclude certain nonexistent error
conditions, and (most importantly) to make it not require write access
to cnp->cn_flags.
This change requires a kernel bump.

hannken | branches: 1.23.8;
Use hashinit() / hashdone() to create the union node hash list.
Cleanup the hash lookup in union_allocvp().
Needs more work as there is still a possible deadlock between
union_allocvp() and vclean().
|
| 1.22 |
| 21-Nov-2011 |
hannken | Replace flag based union node locking with generic vnode lock, support
shared and nowait locks and protect un_uppervp and un_*sz with mutex.
Mark file system MPSAFE.
|
| 1.21 |
| 23-Aug-2011 |
hannken | branches: 1.21.2;
Stop abusing relookup() to prepare the creation of new nodes
in the upper layer.
Replace union_relookup() with union_do_lookup() that prepares
a component, calls VOP_LOOKUP() and does the EEXIST test.
|
| 1.20 |
| 12-Aug-2011 |
hannken | Change some `#ifdef DIAGNOSTIC' to `KASSERT'.
Instead of a `pid_t' use a `lwp_t *' for locking diagnostics.
No functional changes intended.
|
| 1.19 |

hannken | Change union rmdir semantics to fail directory removal for
non-empty directories like all other file systems do.
Change test accordingly.

changes for making DIAGNOSTIC not change the kernel ABI:
- for structure fields that are conditionally present,
make those fields always present.
- for functions which are conditionally inline, make them never inline.
- remove some other functions which are conditionally defined but
don't actually do anything anymore.
- make a lock-debugging function conditional on only LOCKDEBUG.

Tweak sysctl setup functions (the macros, actually) for use in lkms,
and tweak lkminit_*.c (where applicable) to call them, and to call
sysctl_teardown() when being unloaded.
This consists of (1) making setup functions not be static when being
compiled as lkms (change to sys/sysctl.h), (2) making prototypes
visible for the various setup functions in header files (changes to
various header files), and (3) making simple "load" and "unload"
functions in the actual lkminit stuff.
linux_sysctl.c also needs its root exposed (ie, made not static) for
this (when built as an lkm).

thorpej | Undo part of the ktrace/lwp changes. In particular:
* Remove the "lwp *" argument that was added to vget(). Turns out
that nothing actually used it!
* Remove the "lwp *" arguments that were added to VFS_ROOT(), VFS_VGET(),
and VFS_FHTOVP(); all they did was pass it to vget() (which, as noted
above, didn't use it).
* Remove all of the "lwp *" arguments to internal functions that were added
just to appease the above.

vn_readdir() hook by union filesystem when it's loaded & mounted

wrstuden | LWP-ify union fs.
Note: These changes suffer from the same cnp->cn_lwp issue noted for
ufs. They will need to get fixed at the same time as ufs. The fix is to
add struct lwp * as a parameter to some VOPs.
Note also that most of the cn_lwp references used to be cn_proc references,
so if cnp->cn_lwp is bad to use, unionfs's been naughty for quite some
time.
