4730796ca1 Force the length of the sockaddr to be correct for AF_INET and AF_INET6
in bind() and connect().  Linux doesn't care if the length of the
sockaddr matches its address family; FreeBSD does.  This fixes the
known issues with the resolver in linux_base-7.

b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

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.

358325bf4a Only pick up so_error the first time through with EISCONN, as advertised.
The sense of the test was reversed, so we were returning EISCONN, then 0.

0bf301c0ee Correctly emulate linux_connect. For nonblocking sockets, the behavior
is to return EINPROGRESS, EALREADY, (so_error ONCE), EISCONN.  Certain
linux applications rely on the so_error (normally 0) being returned in
order to operate properly.

930a65fe47 Use the linux_connect() on alpha rather than passing directly through
to our native connect().  This is required to deal with the differences
in the way linux handles connects on non-blocking sockets.

This gets the private beta of the Compaq Linux/alpha JDK working

dad3b88ae3 In the words of the submitter:
----
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.

f2477ae13d As described by the submitter:
- emulate Linux IP_HDRINCL behaviour in sendto(): byte order fixed
	  Note that we do an extra getsockopt() on every sendto()
	  to check if the option is set because we don't keep state
	  in the emulator code. Is there a better way to implement
	  this?
	- correct a bug (value of "name" not passed) with
	  getsockopt()

cb226aaa62 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
from the sources.

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

libkvm, ps and other userland struct proc frobbing programs will need
recompiled.

66ff6a3c1b Add IP_OPTIONS and the multicast-related setsockopts to the
list of IP setsockopts the Linux emulator recognizes.

Explicitly disallow IP_HDRINCL since Linux's handling of
raw output is different than BSD's.

Closes PR#kern/2111.

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.

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.
