ff51285d10 Implementation of the modify_ldt syscall. Use the sysarch() interface to do
the actual work. When USER_LDT is not defined for a kernel, sysarch returns
EOPNOTSUPP. Display a message in that case and return ENOSYS to userland.

421ba20de2 Add sysctl variables for the Linuxulator. These reside under `compat.linux' as
discussed on current.

The following variables are defined (for now):

    osname (defaults to "Linux")
        Allow users to change the name of the OS as returned by uname(2),
        specially added for all those Linux Netscape users and statistics
        maniacs :-) We now have what we all wanted!

    osrelease (defaults to "2.2.5")
        Allow users to change the version of the OS as returned by uname(2).
        Since -current supports glibc2.1 now, change the default to 2.2.5
        (was 2.0.36).

    oss_version (defaults to 198144 [0x030600])
        This one will be used by the OSS_GETVERSION ioctl (PR 12917) which I
        can commit now that we have the MIB. The default version number is the
        lowest version possible with the current 'encoding'.

A note about imprisoned processes (see jail(2)):
  These variables are copy-on-write (as suggested by phk). This means that
  imprisoned processes will use the system wide value unless it is written/set
  by the process. From that moment on, a copy local to the prison will be
  used.

A note about the implementation:
  I choose to add a single pointer to struct prison, because I didn't like the
  idea of changing struct prison every time I come up with a new variable. As
  a side effect, the extra storage is only needed when a variable is set from
  within the prison. This also minimizes kernel bloat when the Linuxulator is
  not used; both compiled in or as a module.

c1329f8c5d Major rewrite.
The first reason for this rewrite is KNF conformance.

The second reason is to avoid redundancy. Each function printed the same
string, with only the syscall name being different. The actual printing is now
performed by a single function, which gets the syscall name as an argument.

The third reason is that of convenience. It's now very easy to add a new
dummy implementation. Just add ``DUMMY(foo);'' to the file. It's also a lot
easier now to see if a syscall has a dummy implementation or not.

The dummies are ordered on syscall number. Please maintain this when adding
new dummies (there're 32 candidates at the time of writing :-)

7e26ca1d1a Divorce "dev_t" from the "major|minor" bitmap, which is now called
udev_t in the kernel but still called dev_t in userland.

Provide functions to manipulate both types:
        major()         umajor()
        minor()         uminor()
        makedev()       umakedev()
        dev2udev()      udev2dev()

For now they're functions, they will become in-line functions
after one of the next two steps in this process.

Return major/minor/makedev to macro-hood for userland.

Register a name in cdevsw[] for the "filedescriptor" driver.

In the kernel the udev_t appears in places where we have the
major/minor number combination, (ie: a potential device: we
may not have the driver nor the device), like in inodes, vattr,
cdevsw registration and so on, whereas the dev_t appears where
we carry around a reference to a actual device.

In the future the cdevsw and the aliased-from vnode will be hung
directly from the dev_t, along with up to two softc pointers for
the device driver and a few houskeeping bits.  This will essentially
replace the current "alias" check code (same buck, bigger bang).

A little stunt has been provided to try to catch places where the
wrong type is being used (dev_t vs udev_t), if you see something
not working, #undef DEVT_FASCIST in kern/kern_conf.c and see if
it makes a difference.  If it does, please try to track it down
(many hands make light work) or at least try to reproduce it
as simply as possible, and describe how to do that.

Without DEVT_FASCIST I belive this patch is a no-op.

Stylistic/posixoid comments about the userland view of the <sys/*.h>
files welcome now, from userland they now contain the end result.

Next planned step: make all dev_t's refer to the same devsw[] which
means convert BLK's to CHR's at the perimeter of the vnodes and
other places where they enter the game (bootdev, mknod, sysctl).

performed all sorts of sanity checks. The FreeBSD linux emulator returns
EINVAL in such a case.
Allowing signal 0 to be passed to kill will result in compatible behaviour.

The pointer was only wanted in one place in kern_exec.c.  Applications
should use the kern.ps_strings sysctl instead of PS_STRINGS, so they
shouldn't notice this change.

982e80577d Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

67ea95908f 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.

9b703b1455 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.

4c8218a5c7 Move the "retval" (3rd) parameter from all syscall functions and put
it in struct proc instead.

This fixes a boatload of compiler warning, and removes a lot of cruft

I have not removed the /*ARGSUSED*/, they will require some looking at.

Implement rfork(!RFPROC RFFDG), which divorces the file descriptors for a

Fix the case where a thread does an exec.  It is almost nonsense for a thread

8465726bda 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.

3cb20067de 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.

9995c82494 Initial attempt at getting Linux QMAGIC shared lib support. I have
successfully run linux netscape 2.0b3 with a QMAGIC ld.so and libc/libm

There are still problems..  ld.so claims the libraries are the wrong
format, but it still runs anyway.. :-/  The QMAGIC ld.so also screams
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. :-]

(Lets just say that it puts loads of symlinks in /usr/lib otherwise :-)

efe4e33b17 Clean up some warnings by using the generated structures in <sys/sysproto.h>
for passing to the bsd system calls, rather than inveninting our own
equivalent structures.

b0e92e3fe4 All:
Changed vnodep -> vp for consistency with the rest of the kernel, and
changed iparams -> imgp for brevity.

kern_exec.c:
   Explicitly initialized some additional parts of the image_params struct
to avoid bzeroing it. Rewrote the set-id code to reduce the number of
logical tests. The rewrite exposed a mostly benign bug in the algorithm:
traced set-id images would get ktracing disabled even if the set-id didn't
happen for other reasons.

02d471bd8d Fix the getdirentries of ibcs2 to handle uneven DIRBLKSIZ offsets.
Slight modification from previous fix.

Also, fix problem where an entry would be skipped next call if not enough room
in buffer current call.

1. stepping over syscalls (gdb ni) sends you to DDB, and returned
to the wrong address afterwards, with or without DDB.  patch in
i386/i386/trap.c below.

2. the linux emulator (modload'ed) still causes panics with DIAGNOSTIC,
re-applied a patch posted to one of the lists...

Submitted by:	terry (terry lambert)
This is  a composite of 3 patch sets submitted by terry.
they are:
New low-level init code that supports loadbal modules better
some cleanups in the namei code to help terry in 16-bit character support
some changes to the mount-root code to make it a little more
modular..

NOTE: mounting root off cdrom or NFS MIGHT be broken as I haven't been able
to test those cases..

certainly mounting root of disk still works just fine..
mfs should work but is untested. (tomorrows task)

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
'files' file.

6f51a76158 Modified linux_readdir() function to properly handle Linux readdir()
calls with a byte size of 1.  This special case was not
correctly emulated.  Now programs such as a simple 'ls' to a commercial
Macintosh emulator called 'executor' will work correctly.

f14ea10694 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.
