6c6df91e73 Avoid using the osig* syscalls. 1999-10-10 09:14:31 +00:00
Marcel Moolenaar
956d3333ca sigset_t change (part 4 of 5)
-----------------------------

The compatibility code and/or emulators have been updated:

iBCS2 now mostly uses the older syscalls. SVR4 now properly
handles all signals. This has been achieved by using the
new sigset_t throughout the emulator. The Linuxulator has
been severely updated. Internally the new Linux sigset_t is
made the default. These are then mapped to and from the
new FreeBSD sigset_t.

Also, rt_sigsuspend has been implemented in the Linuxulator.
Implementing this syscall basicly caused all this sigset_t
changing in the first place and the syscall has been used
throughout the change as a means for testing. It basicly is
too much work to undo the implementation so that it can
later be added again.

A special note on the use of sv_sigtbl and sv_sigsize in
struct sysentvec:
Every signal larger than sv_sigsize is not translated and is
passed on to the signal handler unmodified. Signals in the
range 1 upto and including sv_sigsize are translated.
The rationale is that only the system defined signals need to
be translated.

The emulators also have been updated so that the translation
tables are only indexed for valid (system defined) signals.
This change also fixes the translation bug already in the
SVR4 emulator.

8f437f4439 Rename struct members sa_siginfo. POSIX reserves identifiers starting
with sa_ when <signal.h> is included. They would conflict with the
upcoming SA_SIGINFO implementation.

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.

fce002fdef Don't include <sys/ioctl.h> in the kernel. Stage 1: don't include
it when it is not used.  In most cases, the reasons for including it
went away when the special ioctl headers became self-sufficient.

6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

9ce8b2a2f6 Perform special sigset() check.
Make sure signal is not blocked.  If it is, return SIG_HOLD instead
of handler and unblock the signal.

a8a9bde831 In bsd_to_ibcs2_sigaction(), flag for ibcs2 system should be
IBCS2_SA_NOCLDSTOP and not SA_NOCLDSTOP.

77d5b24bcb sigset() should have sa_flags cleared to sig is maked before calling
handler (remove SA_NODEFER).

On the other hand, signal() case should set sa_flags to SA_NODEFER as
in previous change.

In addition, added #ifdef'd code for signal() to or in SA_RESETHAND
flag for when that compatability is implemented.

3b493fe3e8 Use sa_flag option SA_NODEFER in sigsys() emulation because SVR3
does not automatically mask signal upon delivery.

9e03db613c Remove old files no longer needed.
Add new files created for emulator.
Modify NetBSD import to work with FreeBSD and add new features and
code.  The complete emulator is essentially a combination of work/code
implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself,
Steven Wallace.

Features of this new emulator system include:

 o  "clean" code, including strict prototyping.
 o  Auto-generation of ibcs2 system calls, xenix system calls, isc system
calls.  Generation includes system tables, structure definitions,
and prototyping of function calls.
 o  ibcs2 emulator does not rely on any COMPAT_43 system calls.
 o  embedded socksys support
 o  ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel
 o  alternate /emul/ibcs2 namespace searched first for files in ibcs2
system.  Usefull to keep sysv libraries, binaries in /emul/ibcs2.
 o  many other finer details and functions fixed or implemented.

69b770e238 iBCS2 emulator core files.
This is the main files for the iBCS2 emulator. It can be use
compiled into the kernel by using:

options		IBCS2
options 	COMPAT_IBCS2

or as a lkm module using:

options		COMPAT_IBCS2

and then loading it via the ibcs2 script in /usr/bin

REMEMBER: this code is still experimental ! NO WARRENTY !
