4a5470eebd Remove all OpenBSD/NetBSD code. It was the right place to start from, but
it now really gets in the way.

This allows us to fix several problems- not least of which was problems
of ordering about when you'd have a device softc for an miibus child
available or not. Move some steps of things around.

Put the ifnet/arpcom structure at the head of the softc (PR 29249).

Don't do tx gc in the interrupt service routine- that seems to make
things a bit more efficient.

Enable jumbo support by default- but this version of 'jumbo' is broken
because it really is just using multiple tfd/rfd's to match a packet,
which will never be > CLSIZE anyway.

This should begin the first steps toward cleaning this driver up.

cf7ed68316 Add d_thread_t. This is a typedef for struct thread in -current and
will be one for struct proc in stable.  those drivers needing to have
cross version portability should use d_thread_t instead of inventing
their own means.  Non-drivers, and drivers that either only run on
-current or must look under the covers of the struct proc/thread
should must not use this.

As noted in arch@, this minorly violates style(9), but the sys/conf.h
devsw already violates this and all I'm doing is extending the
violation to ease the burdon on device driver writers.  It was judged
that this minor violation, which doesn't impact userland or those
people not using it, was preferable to the alternatives (eg #define
proc thread).  C does not allow a way to rename or alias structs
easily, so we fall back to using a typedef.

Bump FreeBSD_version to reflect this change (porters guide to be done
in a separate commit).

c6ab2f6b4e o Complete the migration from suser error checking in the following form
in vfs_syscalls.c:

    if (mp->mnt_stat.f_owner != p->p_ucred->cr_uid &&
        (error = suser_td(td)) != 0) {
            unwrap_lots_of_stuff();
            return (error);
    }

  to:

    if (mp->mnt_stat.f_owner != p->p_ucred->cr_uid) {
            error = suser_td(td);
            if (error) {
                unwrap_lots_of_stuff();
                return (error);
            }
    }

  This makes the code more readable when complex clauses are in use,
  and minimizes conflicts for large outstanding patchsets modifying the
  kernel authorization code (of which I have several), especially where
  existing authorization and context code are combined in the same if()
  conditional.

b5810bab2d After extensive testing it has been determined that adding complexity
to avoid removing higher level directory vnodes from the namecache has
no perceivable effect and will be removed.  This is especially true
when vmiodirenable is turned on, which it is by default now.  ( vmiodirenable
makes a huge difference in directory caching ).  The vfs.vmiodirenable and
vfs.nameileafonly sysctls have been left in to allow further testing, but
I expect to rip out vfs.nameileafonly soon too.

I have also determined through testing that the real problem with numvnodes
getting too large is due to the VM Page cache preventing the vnode from
being reclaimed.  The directory stuff made only a tiny dent relative
to Poul's original code, enough so that some tests succeeded.  But tests
with several million small files show that the bigger problem is the VM Page
cache.  This will have to be addressed by a future commit.

24efa9d3fa [the previous commit to pseudofs_vncache.c got the wrong log message]
YA pseudofs megacommit, part 2:

 - Merge the pfs_vnode and pfs_vdata structures, and make the vnode cache
   a doubly-linked list.  This eliminates the need to walk the list in
   pfs_vncache_free().

 - Add an exit callout which revokes vnodes associated with the process
   that just exited.  Since it needs to lock the cache when it does this,
   pfs_vncache_mutex needs MTX_RECURSE.

198bc14b1d YA pseudofs megacommit, part 1:
- Add a third callback to the pfs_node structure.  This one simply returns
   non-zero if the specified requesting process is allowed to access the
   specified node for the specified target process.  This is used in
   addition to the usual permission checks, e.g. when certain files don't
   make sense for certain (system) processes.

 - Make sure that pfs_lookup() and pfs_readdir() don't yap about files
   which aren't pfs_visible().  Also check pfs_visible() before performing
   reads and writes, to prevent the kind of races reported in SA-00:77 and
   SA-01:55 (fork a child, open /proc/child/ctl, have that child fork a
   setuid binary, and assume control of it).

 - Add some more trace points.

53036e9289 Begin to implement target mode that for Fibre Channel has a private
per-command component that we *don't* try and pass thru CAM. CAM just
is too risky and too much of a pain- structures get copied, but not
all info of interest can be considered safely transported thru all
consumers (including user space) from the incoming ATIO to the outgoing
CTIO- it's just much safer to have a buddy structure, identified by the
command's tag which *does* make it thru safely.

Pay attention to link speed and report 200MB/s xfer speed for a
23XX card in 2GPs mode.

e5e8823f37 Split the low level trap code into trap, interrupt and syscall, its
easier and hopefully this code is done changing radically.

Don't use the mmu tlb register to address the kernel page table, nor
the 8k pointer register.  The hardware will do some of the page table
lookup by storing the the base address in an internal register and
calculating the address of the tte in the table.  However it is limited
to a 1 meg tsb, which only maps 512 megs.  The kernel page table only
has one level, so its easy to just do it by hand, which has the advantage
of supporting abitrary amounts of kvm and only costs a few more instructions.

Increase kvm to 1 gig now that its easy to do so and so we don't waste
most of a 4 meg page.

Fix some traces.  Fix more proc locking.

Call tsb_stte_promote if we get a soft fault on a mapping in the upper
levels of the tsb.  If there is an invalid or unreferenced mapping
in the primary tsb, it will be replaced.

Immediately fail for faults occuring in {f,s}uswintr.

70a61707f6 Re-enable mbtypes statistics in the mbuf allocator. I disabled these
when I changed the allocator bits. This implements per-CPU mbtypes
stats by keeping net number of decrements/increments of a given mbtype
per-CPU and then summing all of the per-CPU mbtypes to produce the total
net number of allocated mbufs of the given mbtype.
Counters are carefully balanced to avoid/prevent underflows/overflows.

mbtypes stats are re-enabled with the idea that we may occasionally
(although very rarely) observe slight inconsistencies in the stat
reporting. Most of the time, we should be fine, though.

Also make appropriate modifications to netstat(1) and systat(1) to do
the necessary reporting.

a931d7ed29 Make the INADDR_TO_IFP macro use the IP address hash lookup instead of
walking the entire list of IP addresses.

f13ad20660 Introduce network device nodes. Network devices will now automatically
appear in /dev.  Interface hardware ioctls (not protocol or routing) can
be performed on the descriptor.  The SIOCGIFCONF ioctl may be performed
on the special /dev/network node.

ca925d9c17 Add a hash table that contains the list of internet addresses, and use
this in place of the in_ifaddr list when appropriate.  This improves
performance on hosts which have a large number of IP aliases.

80a3cef87d Pseudofs take 2:
- Remove hardcoded uid, gid, mode from struct pfs_node; make pfs_getattr()
   smart enough to get it right most of the time, and allow for callbacks
   to handle the remaining cases.  Rework the definition macros to match.

 - Add lots of (conditional) debugging output.

 - Fix a long-standing bug inherited from procfs: don't pretend to be a
   read-only file system.  Instead, return EOPNOTSUPP for operations we
   truly can't support and allow others to fail silently.  In particular,
   pfs_lookup() now treats CREATE as LOOKUP.  This may need more work.

 - In pfs_lookup(), if the parent node is process-dependent, check that
   the process in question still exists.

 - Implement pfs_open() - its only current function is to check that the
   process opening the file can see the process it belongs to.

 - Finish adding support for writeable nodes.

 - Bump module version number.

 - Introduce lots of new bugs.
