+Drew, Joe, and Brandon.
+
+This file contains my code for the signal functions. I realized that the
+existing signal functions will not suffice. This module should do the
+proper processing for iBCS signals.
+
+There are patches to the emulate module offered by Drew in his pl14n code
+release. The Makefile was changed to include the module.
+
+In addition, I have include a signal.doc file which contains the text from
+my UNIX S5 manual describing the functions used by iBCS. I based the
+emulator code on this document. Please look it over and see if I have
+messed up. I believe it to be correct. However, it never hurts to have
+someone check the work before we can trust it.
+
+It follows what I believe to be the proper calling sequence for signals. I
+sent a message to the IBSC2 group with the text from the McGraw Hill book
+concerning signals. If you would like a copy of the message, then let me
+know.
+
+Of couse, this could be totally wrong. That is the whole point about
+sending this out to a limited distribution.
+
+In addition to the processing for the various function requests, you may
+have noticed that the signal _numbers_ must be changed between the values
+used by iBCS and Linux.
+
+I have had to modify the emulate.c module to export an additional
+procedure (and for emulate.c to use the procedure itself.) In addition, I
+change the branch table to re-direct the signal processing to the signal.c
+module.
+
+I hope that this will help the project when it has been proven workable.
+Please let me know how this turns out -- one way or the other.
+
+If it does work, then I'll give the final code to Drew to merge into the
+master code. That is unless, Drew, you already have it. :-)
+
+Thanks much.

+NAME
+   sigset, sighold, sigrelse, sigignore, sigpause - signal management
+
+SYNOPSIS
+   #include <signal.h>
+
+   void (*sigset (sig, func)) ()
+   int sig;
+   void (*func) ();
+
+   int sighold (sig)
+   int sig;
+
+   int sigrelse (sig)
+   int sig;
+
+   int sigignore (sig)
+   int sig;
+
+   int sigpause (sig)
+   int sig;
+
+DESCRIPTION
+
+These functions provide signal management for application processes. sigset
+specifies the system signal action to be taken upon receipt of signal
+sig. This action is either calling a process signal-catching handler func
+or performing a system-defined action.
+
+Sig can be assigned any one of the following values except SIGKILL. Machine
+or implementation dependent signals are not included (see NOTES below.)
+Each value of sig is a macro, defined in <signal.h>, that expands to an
+integer constant expression.
+
+The following values for the system-defined actions of func are also
+defined in <signal.h>. Each is a macro that expands to a constant
+expression of type pointer to function returning void and has a unique
+value that matches no declarable function.
+
+SIG_DFL - default system action
+Upon receipt of the signal sig, the receiving process is to be terminated
+with all of the consequences outlined in exit(2). In addition a "core
+image" will be made in the current working directory of the receiving
+process if sig is one for which an asterisk appears in the above list and
+the following conditions are met:
+
+      The effective user ID and the real user ID of the receiving process
+      are equal.
+
+      An ordinary file named core exists and is writable or can be created.
+      If the file must be created, it will have the following properties:
+
+            a mode of 0666 modified by the file creating mask
+            [see umask(2)].
+
+            A file owner ID that is the same as the effective
+            user ID of the receiving process.
+
+            A file group ID that is the same as the effective
+            group ID of the receiving process.
+
+SIG_IGN - ignore signal
+Any pending signal sig is discarded and the system signal action is set to
+ignore future occurrences of this signal type.
+
+SIG_HOLD - hold signal
+The signal sig is to be held upon receipt. Any pending signal of this type
+remains held. Only one signal of each type is held.
+
+Otherwise, func must be a pointer to a function, the signal-catching
+handler, that is to be called when signal sig occurs. In this case, sigset
+specifies that the process will call this function upon receipt of signal
+sig. Any pending signal of this type is released. This handler address is
+retained across calls to the other management functions listed here.
+
+When a signal occurs, the signal number sig will be passed as the only
+argument to the signal-catching handler. Before calling the signal-catching
+handler, the system signal action will be set to SIG_HOLD. During normal
+return from the signal-catching handler, the system signal action is
+restored to func and any held signal of this type released. If a non-local
+goto (longjump) is taken, the sigrelese must be called to restore the
+system signal action and release any held signal of this type.
+
+In general, upon return from the signal-catching handler, the receiving
+process will resume execution at the point when it was interrupted.
+However, when a signal is caught during a read(2), a write(2), an open(2),
+or an ioctl(2) system call during a sigpause system call, or during a
+wait(2) system call that does not return immediately due to the existence
+of a previously stopped or zombie process, the signal-catching handler will
+be executed and then the interrupted system call may return a -1 to the
+calling process with errno set to EINTR.
+
+Sighold and sigrelse are used to establish critical regions of
+code. Sighold is analogous to raising the priority level and deferring or
+holding a signal until the priority is lowered by sigrelse. Sigrelse
+restores the system call action to that specified previously by sigset.
+
+Sigignore sets the action for signal sig to SIG_IGN (see above).
+
+Sigpause suspends the calling process until it receives a signal, the same
+as pause(2). However, if the signal sig had been received and held, it is
+released and the system signal action taken. This system call is useful for
+testing variables that are changed on the occurrence of a signal. The
+correct usage is to use sighold to block the signal first, then test the
+variables. If they have not changed, then call sigpause to wait for the
+signal. Sigset will fail if one or more of the following are true:
+
+[EINVAL]  Sig is an illegal signal number (including SIGKILL) or the default
+          handling of sig cannot be changed.
+
+[EINTR]   A signal was caught during the system call sigpause.
+
+DIAGNOSTICS
+Upon successful completion, sigset returns the previous value of the system
+signal action for the specified signal sig. Otherwise, a file of SIG_ERR is
+returned and errno is set to indicate the error. SIGE_ERR is defined in
+<signal.h>.
+
+For the other functions, upon successful completion, a value of 0 is
+returned. Otherwise, a value of -1 is returned and errno is set to indicate
+the error.
+
+SEE ALSO
+kill(2), pause(2), signal(2), wait(2), setjmp(3C)
+
+WARNING
+Two signals that behave differently than the signals described above exist
+in this release of the system:
+
+SIGCLD   death of a child (reset when caught)
+
+SIGPWR   power fail (not reset when caught)
+
+For these signals, func is assigned one of the three values: SIG_DFL,
+SIG_IGN, or a function address. The actions prescribed by these values are
+as follows:
+
+SIG_DFL - ignore signal
+The signal is to be ignored
+
+SIG_IGN - ignore signal
+The signal is to be ignore. Also, if SIGCLD, the calling process's child
+processes will not create zombie processes when the terminate [see exit(2)].
+
+function address - catch signal
+If the signal is SIGPWR, the action to be taken is the same as that
+described above for func equal to function address. The same is true if the
+signal SIGCLD with one exception; while the process is executing the
+signal-catching function, any received SIGCLD signals will be ignore. (This
+is the default action.)
+
+The SIGCLD affects tow other system calls [wait(2), and exit(2)] in the
+following ways:
+
+wait   If the func value of SIGCLD is set to SIG_IGN and a wait is executed,
+       the wait will block until all of the calling process' child process
+       terminate; it will then return a value of -1 with errno set to ECHLD.
+
+exit   If in the existing process's parent process the func value of SIGCLD
+       is set to SIG_IGN, the exiting process will not create a zombie process.
+
+When processing a pipeline, the shell makes the last process in the
+pipeline the parent of the proceeding processes. A process that may be
+piped into in this manner (and thus become the parent of other processes)
+should take care not to set SIGCLD to be caught.
+
+NOTES
+SIGPOLL is issued when a file descriptor corresponding to a STREAMS [see
+intro(2)] file has a "selectable" event pending. A process must
+specifically request that this signal be set using the I_SETSIG ioctl(2)
+call [see streamio(7)]. Otherwise, the process will never receive SIGPOLL.
+
+For portability, applications should use only the symbolic names of signals
+rather than their values and use only the set of signals defined here. The
+action for the signal SIGKILL can not be changed from the default system
+action.
+
+Specific implementations may have other implementation-defined signals.
+Also, additional implementation-defined arguments may be passed to the
+signal-catching handler for hardware-generated signals. For certain
+hardware-generated signals, it may not be possible to resume execution at
+the point of interruption.
+
+The signal type SIGSEGV is reserved for the condition that occurs on an
+invalid access to a data object. If an implementation can detect this
+condition, this signal type should be used.
+
+The other signal management functions, signal(2) and pause(2), should not
+be used in conjunction with these routines for a particular signal type.

+
+This is development level code. It is assumed that you received this code
+in good faith and that you will honor the trust placed in you by the
+developers. Specifically, please do no reveal the location to the development
+code to usenet (newsgroups).
+
+Do not post problems anywhere except the mailing list. Problems about this code
+will not be answered if they are received by any other means.
+
+By using this code, you understand and agree that the code has flaws. Programs
+which you run under this code should not be __trusted__ to operate properly.
+This code has been known to crash the kernel, lock it up, and otherwise 
+require a general reset of the computer; resulting in the loss of all work
+in progress in other screen groups. (We won't assume responsibility if you
+trash your disk because the emulator crashes. Backups are a good thing.)
+
+When the code is ready for release, it will be folded into the released
+kernel. At that time, everyone who gets Linux's kernel will get this code.
+It will not be a separate piece of software.
+
+If you find this to be un-acceptable then you should wait for the general
+release.
+
+
+
+MAILING LIST
+
+Since you had previously joined the mailing list to find the location of the
+development code, this is only documetated for the sake of being complete.
+
+The mail list for this project is located at:  linux-activists@joker.cs.hut.fi.
+Please send all messages to this location. Either include in the header
+or as the first line of the message the following:
+
+X-Mn-Key: IBSC2
+
+[Note, the mail list name is being changed to IBCS2. If the IBSC2 location does
+not work, then use the new name of IBCS2.]
+
+
+
+GENERAL
+
+This directory contains the iBCS emulator. The iBCS emulator, or Intel
+Binary Compatibility Specification, will allow programs written for other
+iBCS systems such as SCO and [sic.] Coherent to work under Linux.
+
+This code is under development. (The last three changes were one day
+apart. Not even Linus updated code so quickly. :-) If you use the code then
+you must accept the fact that it is subject to major revision.
+
+You are welcome to run the code. We do need testers. However, to be a good
+tester, you should be like the pilot of a test aircraft. That is you need
+to keep good notes as to what you did; your configuration; and what the
+results you received. Please try to reduce this as much as possible. (A
+memory dump of your SCO Oracle database run is of not much use without the
+ability to re-create situation. Try to isolate the problem to as small of
+a test case as possible.)
+
+Please see the ToDo list included with the package. It will change over
+time as functionality is added and new requirements are determined. We can
+use any help that your talents may be employed.
+
+Any change to the iBCS emulator must be sent to Drew Sullivan
+<drew@lethe.north.net>. He will coordinate the changes and update the master
+copy of the code. You may post the diff patches to the mail list or send it
+directly to Drew via Email. Either way, Drew will receive a copy. Please do
+not post the article to the list _and_ cc Drew as he will receive two
+copies.

+Tools/apply-patches
+
+
+4. Change ibcs.h to decide if you want to be SCO or SysVr4 compatible.
+This will change when we figure out how to do it dynamically.
+
+#define SCO_COMPAT 1	/* 0 if SysVr4 compatible */
+  
+
+5. Make the kernel. The emulator is used if you select either the COFF
+or ELF object file formats. (If you select both, the you will get the
+emulator as well.)
+
+Instructions on how to make the kernel are include in the /linux/README
+file.
+
+6. Install the kernel. Use either LILO or a separate diskette.
+
+7. Boot that version of the kernel.
+
+8. Run the SCO or iBCS2 programs.
+
+
+
+UTILITIES
+
+The emulator has the ability to trace the events which it processes. The
+program to enable the tracing funcition is contained in the Tools directory.
+
+To make the trace utility, go to the Tools directory and enter the command:
+
+cc -N -o trace -fomit-frame-pointer trace.c
+
+To use the program, enter the command:
+
+trace 1     to enable the trace function or
+trace 0     to disable the trace function.
+
+The result code from the program is the previous setting of the trace event.
+This is probably of no use to anyone who is not writing a script, but that
+is the meaning of the result code if you are curious.
+
+
+
+LIBRARIES
+
+The shared libraries are on the list of ToDo. The libc file is being
+developed by Eric Youndale and me. At the present time, the only way that
+you can use applications which use a shared library is to include the
+shared library from your iBCS system on Linux.
+
+The shared libraries are stored in the directory
+
+/shlib
+
+The libraries are:
+
+libc_s   - standard C runtime library.
+libns_s  - network services library.
+libx11_s - X windows library
+
+Additional libraries may be available on your system. They may be called
+SCOlibc_s or some similar name. Those libraries will not be available for
+Linux. They are specific to the SCO system. It is probably not much of
+concern as the three libraries listed above are the only ones which are
+specified in iBCS specification.
+
+
+
+LIMITATIONS
+
+Until the network services shared library is implemented, the network
+programs probably will not work.
+
+Until the X library is implemented, any X windows application _will_not_work_
+on this system. Even if you use the SCO system's version, there is no hope
+of getting it to work under Linux.

+
+Hugh change for support of the Wyse version of unix and
+mulitple elf/coff personalities.
+**** IF this version works, I want to send the kernel patches to Linus ***
+Code to do single function tracing has been added to emulate.c
+But no support for it in trace.c is there yet.
+Mmap support
+Bug fixes as usual.
+===========================================================================
+# Tue Feb 5, 1994 -- Drew Sullivan <Drew@lethe.north.net> (R1.5)
+
+New document HOWTO -- you should read this
+Replacement for fs/binfmt_coff.c
+Patches for fs/binfmt_elf.c
+(Both can be applied via a new script Tools/apply-patches to
+a new kernel)
+Added sysi86, sysfs, xstat, the start of splitting SCO vs
+ SysVr4 code (See ibcs.h)
+Bug fixes for signal handling
+When built against .99pl15, the perl test set fail with seg faults.
+Some tests work ok, but others are seg faulting.
+===========================================================================
+# Tue Feb 1, 1994 -- Drew Sullivan <Drew@lethe.north.net> (R1.4)
+
+Fixed merging where I lost iABI_errors (needed by new signal.c)
+Fixed merging where I lost ibcs_kill (Now uses new signal mapping)
+Added Al's 2nd little patch to the loader
+Minor fixes to the attribution list in ToDo
+
+*** Ted (tytso@tsx-11.mit.edu) Has given me access to the development
+directory so that files I upload will be available immediately
+===========================================================================
+# Mon Jan 31, 1994 -- Drew Sullivan <Drew@lethe.north.net> (R1.3)
+
+Merged Eric Yongdales sysVr4 systems calls.

+ *  procedure address for the previous setting. This procedure address
+ *  may be negative which is not an error. Therefore, the return processing
+ *  for standard functions is skipped by declaring this routine as a "special"

+ *  Please consider this closely if you plan on changing this mode.
