sys/compat: Memset zero before copyout.

Just in case of uninitialized padding which would lead to kernel
stack disclosure.  If the compiler can prove the memset redundant
then it can optimize it away; otherwise better safe than sorry.

Resolve a couple of conflicts (result of the uimin/uimax changes)

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

Per discussion with ad, remove most of the #include <sys/sa.h> lines
as they were including sa.h just for the type(s) needed for syscallargs.h.

Instead, create a new file, sys/satypes.h, which contains just the
types needed for syscallargs.h. Yes, there's only one now, but that
may change and it's probably more likely to change if it'd be difficult
to handle. :-)

Per discussion with matt at n dot o, add an include of satypes.h to
sigtypes.h. Upcall handlers are kinda signal handlers, and signalling
is the header file that's already included for syscallargs.h that
closest matches SA.

This shaves about 3000 lines off of the diff of the branch relative
to the base. That also represents about 18% of the total before this
checkin.

I think this reduction is very good thing.

Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

and unbork some more changes.

Change the way that emulations locate files within the emulation root to
  avoid having to allocate space in the 'stackgap'
  - which is very LWP unfriendly.
The additional code for non-emulation namei() is trivial, the reduction for
  the emulations is massive.
The vnode for a processes emulation root is saved in the cwdi structure
  during process exec.
If the emulation root the TRYEMULROOT flag are set, namei() will do an initial
  search for absolute pathnames in the emulation root, if that fails it will
  retry from the normal root.
".." at the emulation root will always go to the real root, even in the middle
  of paths and when expanding symlinks.
Absolute symlinks found using absolute paths in the emulation root will be
  relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links
  inside the emulation root don't need changing).
If the root of the emulation would be returned (for an emulation lookup), then
  the real root is returned instead (matching the behaviour of emul_lookup,
  but being a cheap comparison here) so that programs that scan "../.."
  looking for the root dircetory don't loop forever.
The target for symbolic links is no longer mangled (it used to get the
  CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended).
CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding
  TRYEMULROOT to the flags to NDINIT().
A lot of the emulation system call stubs could now be deleted.

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it.  This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

More changes for providing lwpid for ktrace (sparc GENERIC built)

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

No longer need to pull in lwp.h; proc.h pulls it in for us.

Add kernel support for having userland provide the signal trampoline:

* struct sigacts gets a new sigact_sigdesc structure, which has the
  sigaction and the trampoline/version.  Version 0 means "legacy kernel
  provided trampoline".  Other versions are coordinated with machine-
  dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
  the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
  trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions.  Instead,
  sendsig() looks up the handler by peeking in the sigacts for the
  process getting the signal (since it has to look in there for the
  trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
  its arguments based on the trampoline version in the sigacts.

Changes to libc to use the new facility will be checked in later.  Kernel
version not bumped; we will ride the 1.6C bump made recently.

Fix a partial construction problem that can cause race conditions
between creation of a file descriptor and close(2) when using kernel
assisted threads.  What we do is stick descriptors in the table, but
mark them as "larval".  This causes essentially everything to treat
it as a non-existent descriptor, except for fdalloc(), which sees a
filled slot so that it won't (incorrectly) allocate it again.  When
a descriptor is fully constructed, the code that has constructed it
marks it as "mature" (which actually clears the "larval" flag), and
things continue to work as normal.

While here, gather all the code that gets a descriptor from the table
into a fd_getfile() function, and call it, rather than having the
same (sometimes incorrect) code copied all over the place.

Significantly restructure the way signal state for a process is stored.
Rather than using bitmasks to redundantly store the information kept

hang sigacts directly off the process, and access it directly.

Simplify signal setup code tremendously by storing information in
the sigacts as an array of struct sigactions, rather than in a different
format, since userspace uses sigactions.

NFSCLIENT -> NFS

Snapshot of work-in-progress, committed to private branch.

These changes implement machine-independent root device and file system
selection.  Notable features:

	- All ports behave in a consistent manner regarding root
	  device selection.
	- No more "options GENERIC"; all kernels have the ability
	  to boot with RB_ASKNAME to select root device and file system
	  type.
	- Root file system type can be wildcarded; a machine-independent
	  function will try all possible file systems for the selected
	  root device until one succeeds.
	- If the root file system fails to mount, the operator will
	  be given the chance to select a new root device and file
	  system type, rather than having the machine simply panic.
	- nfs_mountroot() no longer panics if any part of the NFS
	  mount process fails; it now returns an error, giving the
	  operator a chance to recover.
	- New, more consistent, config(8) grammar.  The constructs:

		config netbsd swap generic
		config netbsd root on nfs

	  have been replaced with:

		config netbsd root on ? type ?
		config netbsd root on ? type nfs

	  Additionally, the operator may select or wildcard root file
	  system type in the kernel configuration file:

		config netbsd root on cd0a type cd9660

	  config(8) now requires that a "root" specification be
	  made.  "root" may be wired down or wildcarded.  "swap" and
	  "dump" specifications are optional, and follow previous
	  semantics.

	- config(8) has a new "file-system" keyword, used to configure
	  file systems into the kernel.  Eventually, this will be used
	  to generate the default vfssw[].

	- "options NFSCLIENT" is obsolete, and is replaced by
	  "file-system NFS".  "options NFSSERVER" still exists, since
	  NFS server support is independent of the NFS file system
	  client.

	- sys/arch/<foo>/<foo>/swapgeneric.c is no longer used, and
	  will be removed; all information is now generated by config(8).

As of this commit, all ports except arm32 have been updated to use
the new setroot().  Only SPARC, i386, and Alpha ports have been
tested at this time.  Port masters should test these changes on their
ports, and report any problems back to me.

More changes are on their way, including RB_ASKNAME support in
nfs_mountroot() (to prompt for server address and path) and, potentially,
the ability to select rarp/bootparam or bootp in nfs_mountroot().

This recently stopped compiling due to a warning about const being
dropped. This fix suggested by cgd.

pay a small amount of lip service to the new syscall args mechanism.
In reality, none of these will compile.

use STACKGAPBASE

New RCS ID's, take two.  they're more aesthecially pleasant, and use 'NetBSD'

sun_mount: fill in one more field.

async_daemon only if NFSCLIENT

Adapt to 4.4-lite.

Minor change.

tricky

maxfdescs -> maxfiles

iszerodev

fix uname after sysctl

p->p_sig -> p->p_siglist

fix my forgetfulness; from gwr

expand the rlimit struct, kill last vestiges of off_t bogosity.

kill syscall name aliases. no user-visible changes

SunOS's RLIMIT_NOFILE is different: add sun_[gs]rlimit().

make sunos mount(2) work again

sickness to get SunOS mmap right

expand uid_t/gid_t/off_t

DoH!

first cut at a SUNOS_COMPAT sysconf() system call.

place conditional around sun_nfssvc.

make sun_misc compile without NFSSERVER. thanks to
Niklas Hallqvist <niklas@appli.se>

m68k/sparc sunos binary compatibility code, pulled down from magnum branch
for consumption by the m68k masses

Introduced sun_mknod() which also deals with FIFOs (ie. `mknod xxx p' on SunOS).

impliment fstatfs() and statfs() better

very rudimentary exportfs(2) support, ie. "return 0"

statfs(2) and fstatfs(2) support. `df' now works.

add vhangup(2)
generalize m68k support for /dev/zero..

add real wimpy quotactl(2) emulation

add basically bogus ustat(2) support.

nfssvc(2) system call emulation. might work, might not -- have to
wait for exportfs(2) support for mountd..

added mount(2) nfs support

moved from arch/sparc/sunos to compat/sunos

new compat functions: sun_open, sun_auditsys, sun_setpgid, sun_uname
some from Markus.

specdev.h moves

silly typo

support both sun3 & sparc concepts of minor/major #'s for /dev/zero

fix sun_getdents()
fix sun_mmap()
Note: delete the "struct dirent" in here when sys/dirent.h is created.

Add a stub auditsys() system call that does nothing.
SunOS /sbin/fsck calls it..

various changes, suffice to say that 4.4 syscalls do not look like ours

Chris Torek's sparc port. Missing lots of things.
