f4e2c07e73 Add a simple printf() based debug facility to the new nfs client.
Use it for a printf() that can be harmlessly generated for mmap()'d
files. It will be used extensively for the NFSv4.1 client.
Debugging printf()s are enabled by setting vfs.nfs.debuglevel to
a non-zero value. The higher the value, the more debugging printf()s.

d9e9650a36 Allow shared lookups for nullfs mounts, if lower filesystem supports
it.  There are two problems which shall be addressed for shared
lookups use to have measurable effect on nullfs scalability:

1. When vfs_lookup() calls VOP_LOOKUP() for nullfs, which passes lookup
operation to lower fs, resulting vnode is often only shared-locked. Then
null_nodeget() cannot instantiate covering vnode for lower vnode, since
insmntque1() and null_hashins() require exclusive lock on the lower.

Change the assert that lower vnode is exclusively locked to only
require any lock.  If null hash failed to find pre-existing nullfs
vnode for lower vnode and the vnode is shared-locked, the lower vnode
lock is upgraded.

2. Nullfs reclaims its vnodes on deactivation. This is due to nullfs
inability to detect reclamation of the lower vnode.  Reclamation of a
nullfs vnode at deactivation time prevents a reference to the lower
vnode to become stale.

Change nullfs VOP_INACTIVE to not reclaim the vnode, instead use the
VFS_RECLAIM_LOWERVP to get notification and reclaim upper vnode
together with the reclamation of the lower vnode.

Note that nullfs reclamation procedure calls vput() on the lowervp
vnode, temporary unlocking the vnode being reclaimed. This seems to be
fine for MPSAFE filesystems, but not-MPSAFE code often put partially
initialized vnode on some globally visible list, and later can decide
that half-constructed vnode is not needed.  If nullfs mount is created
above such filesystem, then other threads might catch such not
properly initialized vnode. Instead of trying to overcome this case,
e.g. by recursing the lower vnode lock in null_reclaim_lowervp(), I
decided to rely on nearby removal of the support for non-MPSAFE
filesystems.

bcd5bb8e57 Add a facility for vgone() to inform the set of subscribed mounts
about vnode reclamation. Typical use is for the bypass mounts like
nullfs to get a notification about lower vnode going away.

Now, vgone() calls new VFS op vfs_reclaim_lowervp() with an argument
lowervp which is reclaimed. It is possible to register several
reclamation event listeners, to correctly handle the case of several
nullfs mounts over the same directory.

For the filesystem not having nullfs mounts over it, the overhead
added is a single mount interlock lock/unlock in the vnode reclamation
path.

84c3cd4f19 Add MNTK_LOOKUP_EXCL_DOTDOT struct mount flag, which specifies to the
lookup code that dotdot lookups shall override any shared lock
requests with the exclusive one. The flag is useful for filesystems
which sometimes need to upgrade shared lock to exclusive inside the
VOP_LOOKUP or later, which cannot be done safely for dotdot, due to
dvp also locked and causing LOR.

The non-11n setds function is called when TXing aggregate frames (and

the delimiter field.  I figure it's nicer to do that.

Avoid re-walking the page table from the root for every PTE examined.

  Tidy up some of pmap_remove()'s helper functions.

pmap_enter:

  Set PV_TABLE_REF whenever the physical page being mapped is managed, not
  just when it is writeable.

  Only call pmap_update_page() when the old mapping was valid.  If there was
  no prior valid mapping, then pmap_update_page() serves no useful purpose.
  However, it will interrupt every processor that has the pmap active.

0cf0d912b7 The first part of check_priv() function, that attempts to obtain creds
from the control message, actually never worked. This means check_priv()
didn't work for local dgram sockets.

The SCM_CREDS control messages is received only in two cases:

1) If we did setsockopt(LOCAL_CREDS) on our socket, and in this case
   the message is struct sockcred.
2) If sender did supplied SCM_CREDS control message in his sendmsg()
   syscall. In this case the message is struct cmsgcred.

We can't rely on 2), so we will use 1) for dgram sockets. For stream
sockets it is more reliable to obtain accept-time credentials, since
SCM_CREDS control message is attached only on first read. Thus:

o Do setsockopt(LOCAL_CREDS) on local dgram sockets.
o Split check_priv() into check_priv_stream() and check_priv_dgram(),
  and call them from recv_stream() and recv_dgram() respectively.
o Don't provide space for SCM_CREDS control message in recv_stream().
o Provide space for SCM_CREDS control message in recv_dgram(), but there
  is no need to initialize anything in it.
o In recv_dgram() do not blindly expect that first message is SCM_CREDS,
  instead use correct search cycle through control messages.

d6d3f01e0a Merge the projects/pf/head branch, that was worked on for last six months,
into head. The most significant achievements in the new code:

 o Fine grained locking, thus much better performance.
 o Fixes to many problems in pf, that were specific to FreeBSD port.

New code doesn't have that many ifdefs and much less OpenBSDisms, thus
is more attractive to our developers.

projects/pf/head branch. And for reference, here is exact list of

76af1a93c9 Correctly mask out the RTS/CTS flags when forming aggregates.
This had the side effect of clearing HAL_TXDESC_CLRDMASK for a bunch of
frames, meaning they'd end up being potentially filtered if there were
an error.  This is fine in the previous world as they'd just be
software retried but now that I'm working on filtered frames, these
descriptors would be endlessly retried until another valid frame would
come along that had CLRDMASK set.
