3193579b66 o Remove @- from the ln and change it to a -sf. This was bogus, and
regocnized as such at the time.  Now that the other bogons in the
  tree have been fixed, we can remove this ugly kludge.
o Remove stale/bogus opt_foo.h files.  These are left over from
  by-gone resources.  And they point to the need, yet again, to
  improve the build system so meta information is only in one place.

c503d8706c opt_kstack_pages.h is not needed anymore. It would have been a Bad Thing

27d29f428c Unbreak the modules build:
- add dependencies on opt_cpu.h and opt_kstack_pages.h to the linux module
  Makefile in the i386 case. The latter is needed by an i386-only file, the
  former by the i386 implementation of linux_sysvec.c (opt_cpu.h is used for
  architecture-dependent options, so I added it only for i386, although this
  file is also generated for the alpha).
- add a dependency on opt_kstack_pages.h to the pecoff module Makefile.

eddc160e00 Introduce support for Mandatory Access Control and extensible
kernel access control.

Invoke appropriate MAC entry points for a number of VFS-related
operations in the Linux ABI module.  In particular, handle uselib
in a manner similar to open() (more work is probably needed here),
as well as handle statfs(), and linux readdir()-like calls.

but at least linprocfs works (I haven't had the opportunity to test other

5c465126bf Pass maintainership over to emulation@FreeBSD.org. It has been fun,
but time and other interests is making it hard. Open the door for

5002a60f9b Round of cleanups and enhancements. These include (in random order):
o  Introduce private types for use in linux syscalls for two reasons:
   1. establish type independence for ease in porting and,
   2. provide a visual queue as to which syscalls have proper
      prototypes to further cleanup the i386/alpha split.
   Linuxulator types are prefixed by 'l_'. void and char have not
   been "virtualized".

o  Provide dummy functions for all syscalls and remove dummy functions
   or implementations of truely obsolete syscalls.

o  Sanitize the shm*, sem* and msg* syscalls.

o  Make a first attempt to implement the linux_sysctl syscall. At this
   time it only returns one MIB (KERN_VERSION), but most importantly,
   it tells us when we need to add additional sysctls :-)

o  Bump the kenel version up to 2.4.2 (this is not the same as the
   KERN_VERSION MIB, BTW).

o  Implement new syscalls, of which most are specific to i386. Our
   syscall table is now up to date with Linux 2.4.2. Some highlights:
   -  Implement the 32-bit uid_t and gid_t bases syscalls.
   -  Implement a couple of 64-bit file size/offset bases syscalls.

o  Fix or improve numerous syscalls and prototypes.

o  Reduce style(9) violations while I'm here. Especially indentation
   inconsistencies within the same file are addressed. Re-indenting
   did not obfuscate actual changes to the extend that it could not
   be combined.

NOTE: I spend some time testing these changes and found that if there
      were regressions, they were not caused by these changes AFAICT.
      It was observed that installing a RH 7.1 runtime environment
      did make matters worse. Hangs and/or reboots have been observed
      with and without these changes, so when it failed to make life
      better in cases it doesn't look like it made it worse.

055d495677 Fix linux_getcwd() so that if the cwd isn't cached (__getcwd() fails),
the cwd is looked up inside the kernel. The native getcwd() in libc
handles this in userland if __getcwd() fails.

59807abe47 Retire linux(8). Using shell scripts to load kernel loadable modules is
out of fashion.  This particular case, unlike joy(8) and friends which
are just plain silly, did more than just load a kernel loadable module.
However, /etc/rc and the linux_base port were adjusted a while back to
cope with the absence of this script.

The only outstanding reason to hang on to it would have been for the
linux(8) manual page, which clued folks into the existence of the
Linuxulator.  A new linux(4) was introduced a while back.  It does
a much better job.

This script just isn't useful any more.

56ca39961b Pull in sys/conf/kmod.mk, rather than /usr/share/mk/bsd.kmod.mk.
This means that the kernel can be totally self contained now and is not
dependent on the last buildworld to update /usr/share/mk.  This might
also make it easier to build 5.x kernels on 4.0 boxes etc, assuming
gensetdefs and config(8) are updated.

27e2d53c58 Compile linux_genassym.c with ordinary ${CFLAGS}. The (small) need for
-U_KERNEL became negative when all all the genassym.c's were converted
to be cross-built.

Use "genassym ... > ${.TARGET}", not "genassym -o $@ ...", so that
genassym(1) doesn't need to support -o.

c6dfea0ebd 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.
