836e5d1360 In order to fix some concurrency problems with the swap pager early
on in the FreeBSD development, I had made a global lock around the
rlist code.  This was bogus, and now the lock is maintained on a
per resource list basis.  This now allows the rlist code to be used for
almost any non-interrupt level application.

185dc76169 Deal with NetBSD byte-swapped a.out magic when checking the MID to exclude
linux binaries from the *BSD a.out loader. This is a hack, but lets me run
static NetBSD binaries.  Dynamic binaries are a much bigger problem because
the shared libraries would conflict with our native libraries, so a
/compat/netbsd alternate namespace and translation would be needed.

ef5dc8a96d Keep fork from over extending the number of processes. Since u_map is
sized exactly for maxproc, the occasional overrunning the maxproc limit
can cause problems.

4f735d8edb Add support for the old-style Linux termio (not termios) TCGETA etc.
Also, LINUX_POSIX_VDISABLE is \0, FreeBSD's is 0xff. Convert between them.

This enables some more programs to run, including the Livingston Portmaster
utilities (PMtools).

66fa281751 Close PR#17. This may be a contraversal fix in that now mount will
spit out two error lines for a bogus filesystem type, e.g:

root@time-> mount -t foo /dev/sd0a /mnt
mount: exec /sbin/mount_foo for /mnt: No such file or directory
mount: exec /usr/sbin/mount_foo for /mnt: No such file or directory

But I would submit that if you're even going to scan multiple directories
for a mount_foo (which I actually think is somewhat bogus - if it's not
in /sbin, you're probably in big trouble anyway), you should emit an error
for each one.  I got multiple complaints (in addition to the PR) that the
existing behavior was very confusing.

7e6ace8561 If the send() to the AF_UNIX socket to the syslogd fails, attempt to
reconnect once using the saved openlog() parameters.

This helps one of the system startup race conditions. If syslogd takes too
long to get going, some daemons can fail the connection and forever log
to the console even though the syslogd is running.  That is ..unfortunate..

d66a506616 Mega-commit for Linux emulator update.. This has been stress tested under
netscape-2.0 for Linux running all the Java stuff.  The scrollbars are now
working, at least on my machine. (whew! :-)

I'm uncomfortable with the size of this commit, but it's too
inter-dependant to easily seperate out.

The main changes:

COMPAT_LINUX is *GONE*.  Most of the code has been moved out of the i386
machine dependent section into the linux emulator itself.  The int 0x80
syscall code was almost identical to the lcall 7,0 code and a minor tweak
allows them to both be used with the same C code.  All kernels can now
just modload the lkm and it'll DTRT without having to rebuild the kernel
first.  Like IBCS2, you can statically compile it in with "options LINUX".

A pile of new syscalls implemented, including getdents(), llseek(),
readv(), writev(), msync(), personality().  The Linux-ELF libraries want
to use some of these.

linux_select() now obeys Linux semantics, ie: returns the time remaining
of the timeout value rather than leaving it the original value.

Quite a few bugs removed, including incorrect arguments being used in
syscalls..  eg:  mixups between passing the sigset as an int, vs passing
it as a pointer and doing a copyin(), missing return values, unhandled
cases, SIOC* ioctls, etc.

The build for the code has changed.  i386/conf/files now knows how
to build linux_genassym and generate linux_assym.h on the fly.

Supporting changes elsewhere in the kernel:

The user-mode signal trampoline has moved from the U area to immediately
below the top of the stack (below PS_STRINGS).  This allows the different
binary emulations to have their own signal trampoline code (which gets rid
of the hardwired syscall 103 (sigreturn on BSD, syslog on Linux)) and so
that the emulator can provide the exact "struct sigcontext *" argument to
the program's signal handlers.

The sigstack's "ss_flags" now uses SS_DISABLE and SS_ONSTACK flags, which
have the same values as the re-used SA_DISABLE and SA_ONSTACK which are
intended for sigaction only.  This enables the support of a SA_RESETHAND
flag to sigaction to implement the gross SYSV and Linux SA_ONESHOT signal
semantics where the signal handler is reset when it's triggered.

makesyscalls.sh no longer appends the struct sysentvec on the end of the
generated init_sysent.c code.  It's a lot saner to have it in a seperate
file rather than trying to update the structure inside the awk script. :-)

At exec time, the dozen bytes or so of signal trampoline code are copied
to the top of the user's stack, rather than obtaining the trampoline code
the old way by getting a clone of the parent's user area.  This allows
Linux and native binaries to freely exec each other without getting
trampolines mixed up.

9154ee6aec Oops.. I nearly forgot the actual core of the length/rounding/etc fixes
that Bruce asked for.

These still are not quite perfect, and in particular, it can get
upset on extreme boundary cases (addr = 0xfff, len = 0xffffffff,
which would end up mapping a single page rather than failing), but
this is better code that I committed before.

(note, the VM system does not (apparently) support single mmap segment
sizes above 0x80000000 anyway)

6538dda3dc 1) Fix a bug that a buffer is removed from a queue, but the
queue type is not set to QUEUE_NONE.  This appears to have
	caused a hang bug that has been lurking.
2)	Fix bugs that brelse'ing locked buffers do not "free" them, but the
	code assumes so.  This can cause hangs when LFS is used.
3)	Use malloced memory for directories when applicable.  The amount
	of malloced memory is seriously limited, but should decrease the
	amount of memory used by an average directory to 1/4 - 1/2 previous.
	This capability is fully tunable.  (Note that there is no config
	parameter, and might never be.)
4)	Bias slightly the buffer cache usage towards non-VMIO buffers.  Since
	the data in VMIO buffers is not lost when the buffer is reclaimed, this
	will help performance.  This is adjustable also.

9d2baf5cdf Update the Connectix QuickCam driver to match my current work.
- split driver into FreeBSD specific and camera specific portions
  (qcamio.c can run in user mode, with a Linux "driver top" etc,
   and qcam.c should be trivial to port to NetBSD and BSDI.)
- support for 4bppand bidirectional transfers working better
- start of interleaved data-transfers byte-stream decodes (some of this
  stuff has been pulled out for the moment to make it easier to debug)

At this point, anyone who wants to port it to other platforms should feel
free to do so.  Please feed changes directly back to me so that I can produce
a unified distribution.
