22d4b0fb41 Add provisions for variant core dump file formats, depending on the
object format of the executable being dumped.  This is the first
step toward producing ELF core dumps in the proper format.  I will
commit the code to generate the ELF core dumps Real Soon Now.  In
the meantime, ELF executables won't dump core at all.  That is
probably no less useful than dumping a.out-style core dumps as they
have done until now.

2394cd9adb Initial support for using linux X servers under emulation - to use an
XFree86 server, users need to create the following links in their
/compat/linux/dev directory (assuming kernel configured with 4 VTs).

lrwxrwxrwx  1 root  wheel  7 Aug 30 22:59 tty0 -> console
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty1 -> ttyv0
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty2 -> ttyv1
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty3 -> ttyv2
lrwxrwxrwx  1 root  wheel  5 Aug 30 22:45 tty4 -> ttyv3

VT switching is still not yet supported. Attempting to switch VT
currently will cause Xserver bus error.

24382fa41f Oops, the previous fix confused Linux's sigset_t with a pointer type.
It can be integral or a struct in POSIX, so it is difficult to print,
but it is actually declared as unsigned long.  Assume that it is
unsigned integral.

882fdeae66 Converted the second last instance of hzto() to tvtohz().
Fixed nearby bugs (in linux_alarm()):
- the itimer for the alarm was relative to the epoch instead of relative
  to the boot time.  This was harmless because the itimer's interval is 0.
- the seconds arg was not checked for validity before converting it to a
  possibly different value.
- printf format errors.

Improvements:
Don't use splclock().  splsoftclock() suffices.  Don't complicate things
by micro-optimizing interrupt latency.

Minor improvements:
Various micro-optimizations to exploit the specialness of the alarm itimer
and the value 0.

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

Poul-Henning Kamp
227ee8a188 Eradicate the variable "time" from the kernel, using various measures.
"time" wasn't a atomic variable, so splfoo() protection were needed
around any access to it, unless you just wanted the seconds part.

Most uses of time.tv_sec now uses the new variable time_second instead.

gettime() changed to getmicrotime(0.

Remove a couple of unneeded splfoo() protections, the new getmicrotime()
is atomic, (until Bruce sets a breakpoint in it).

A couple of places needed random data, so use read_random() instead
of mucking about with time which isn't random.

Add a new nfs_curusec() function.

Mark a couple of bogosities involving the now disappeard time variable.

Update ffs_update() to avoid the weird "== &time" checks, by fixing the
one remaining call that passwd &time as args.

Change profiling in ncr.c to use ticks instead of time.  Resolution is
the same.

Add new function "tvtohz()" to avoid the bogus "splfoo(), add time, call
hzto() which subtracts time" sequences.

----
I've worked to enhance the connect() patches.

I've just tested this with the Linux JDK appletviewer on an applet
that does a lot of connects, and it works as well as during my
previous tests.

The connect() patch is now a merge between my older patch and the
OpenBSD stuff. It ensures that any async error is returned by
connect() instead of getsockopt(SOL_SOCKET, SO_ERROR) as reasonnable
systems do.

There are also minor patches to implement IPPROTO_TCP for
get/setsocktopt(). These are also tested (with Linux Apache).
----

I would appreciate any feedback regarding these changes, as they'd
be very useful in 2.2.6.

The fix involves negative logic.  Named pipes are now distinguished from
other types of files with vnodes, and there is additional code to handle
vnodes and named pipes in the same way only where that makes sense (not
for lseek, locking or TIOCSCTTY).

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.

5297fc55c8 This is an extract of changes from what I am currently running...
- Optimise the linux a.out loading and uselib system calls so they
  take advantage of some of John's recent interface improvements.
  Basically, this means they make far less map changes than before.
- Attempt to plug some potentially nasty kernel_map memory leaks..
- Improve support for QMAGIC libs (I only use QMAGIC (ie: a.out libraries from
  the slackware 3.0 dist) but this depends on other changes to enhance
  the /compat/linux support)
- uselib goes out through a single exit as part of the resource tracking
  that I did when closing the resource leaks on errors.  This could be
  cleaner than what I did, but making a 30-deep nested if/else was not my
  idea of fun, neither did I want to repeat the same code 30 times over for
  each failure possibility.  I guess this function needs to be split into
  smaller functions to solve this.

I've been running the Linux Netscape-2.0 (with Java) to test this, and apart
from the long-standing problem with the missing scrollbars, it appears to
still work as before with ZMAGIC libs (and the leaks)..  However, I've
been using it with mods for the signal trampoline code for native linux stack
frames on signals and exterminated the blasted sigreturn printf() problem,
so I can't be certain that there is not a dependency on something else.

There are still problems..  ld.so claims the libraries are the wrong

about needing ld.so.cache, and running a linux ldconfig is quite
educational.  You soon learn to run "chroot /compat/linux /bin/ldconfig"
where ldconfig is living in /compat/linux/bin. :-]

The low level init stuff includes a total rewrite of init_main.c
to make it possible for new modules to have an init phase by simply
adding an entry to a TEXT_SET (or is it DATA_SET) list. thus a new module can
be added to the kernel without editing any other files other than the

c0e5de7d88 Moved setting of VTEXT flag into the appropriate image activators. This
fixes a bug where linux binaries would get the flag set inappropriately.

c21dee177f First incarnation of our Linux emulator or rather compatibility code.
This first shot only incorporaties so much functionality that DOOM
can run (the X version), signal handling is VERY weak, so is many
other things. But it meets my milestone number one (you guessed it
- running DOOM).

Uses /compat/linux as prefix for loading shared libs, so it won't
conflict with our own libs.

Kernel must be compiled with "options COMPAT_LINUX" for this to work.
