029b0fc88f Fix tracing of syscalls. The previous fix required the undocumented
option DDB_NO_LCALLS to stop ddb getting control and broke all ddb
tracing.  Now there is no option and no way for ddb to trace at
address _Xsyscall or to _Xsyscall, but tracing everywhere else
works.  The previous fix did unnecessary things for Linux syscalls.

Don't bother checking that syscall frames are for user mode.

Make debugger traps inside the kernel (except at addresses _Xsyscall
and _Xsyscall+1) fatal if ddb is not configured.  They "can't happen".

Add prototypes.

Remove stupid comments, e.g., /*ARGSUSED*/ for args that are used.

write-side needs rewriting, but this makes a ktrace panic go away for
now.

"zero' and 'junk' options to help find and diagnose malloc abuse.
EXTRA_SANITY defaults "junk" to on.
Don't dump the internal state, unless EXTRA_SANITY.
General code cleanup.
Error messages cleaned up a bit, more checking earlier.
EXTRA_SANITY is default at this time (just in case).
Performance (without EXTRA_SANITY) is better, beats gnumalloc in
both time & space most of the time:

eec7e07a40 Identify the 2940 *Ultra* SCSI adapter. We treat it as a normal 2940
for now since I don't have any documentation on this card yet and it
is software compatible with the earlier cards.

The 2940 *Ultra* is Adaptec's push to take SCSI to 20MHz bus rates.  Its
based on the aic7880 chip which is the successor to the aic7870.

a9c6b5df9c 1. Add a settable redial timer and logging of the process id in a file.
A settable redial timer helps to avoid the problem where both ends
   of a link want to dial at the same time and the line winds up busy
   for both ends. The process id is logged in /var/run/PPP.system where
   system is the name of the called system.  When both ends of a link
   are running in demand dial mode, you need an easy way to get the pid
   of the ppp on the called end so it can be killed and re-started with
   -direct or pppd started to handle the incoming ppp session.

2. Add secret description for "set timeout" to man.

ad7507e248 Remove prototype definitions from <sys/systm.h>.
Prototypes are located in <sys/sysproto.h>.

Add appropriate #include <sys/sysproto.h> to files that needed
protos from systm.h.

Add structure definitions to appropriate files that relied on sys/systm.h,
right before system call definition, as in the rest of the kernel source.

In kern_prot.c, instead of using the dummy structure "args", create
individual dummy structures named <syscall>_args.  This makes
life easier for prototype generation.

93c9414e49 Remove compat_43 psuedo-argument hack, and replace with a better hack.
Instead of using a fake "compat" argument, pass a real compat int to function
if COMPAT_43 is defined.  Functions involved: wait4, accept, recvfrom,
getsockname.

With the compat psuedo-argument, this introduces an argument structure
that can have two possible sizes depending on compat options.
This makes life difficult for lkm modules like ibcs2, which would
have to guess what size used in kernel when compiled.  Also,
the prototype generator for these structures cannot generate proper sizes.

Now there is only one fixed structure and makes everybody happy.

I recommend these changes be introduced to 2.1 so that ibcs2, linux
lkm's generated for 2.2 can still run on a 2.1 kernel.

27e79e1d84 Handle trailing slashes in source filenames correctly. E.g., rewrite
`mv foo/ ../..' to `mv foo/ ../../foo/', not to `mv foo/ ../../'.  The
latter caused a panic.  Before the trailing slash changes in the kernel,
the trailing slashes caused the rename() for this mv to fail earlier, so
there was no panic in 2.0.

Fixes part of PR 760.

4887ee51b2 Remake generated files to reflect makesyscalls.sh changes 1995-10-07 06:29:30 +00:00

f171307e84 Add new functionality to makesyscalls.sh:
o  optional config-file to set vars: sysnames, sysproto, sysproto_h,
	syshdr, syssw, syshide, syscallprefix, switchname, namesname, sysvec.
  o  change syntax of syscalls.master entry:
	remove argument count.
	add pseudo-prototype field defining function name and arguments.
  o  generates correct structure definitions for all system calls
	in sys/sysproto.h
  o  add type NOARGS:  same as STD except do not create structure in
	sys/sysproto.h
  o  add type NOPROTO:  same as STD except do not create structure or function
	prototype in sys/sysproto.h

New functionality provides complete prototype definitions.
Usefull for generating files for emulated systems like my new ibcs2 code.

Update syscalls.master to reflect new changes.  For example, read()
entry now looks like:

3	STD	POSIX	{ int ibcs2_read(int fd, char *buf, u_int nbytes); }

This is similar to how NetBSD generates these files.

eb6c139019 Some NIS bug stomping:
- In some cases, we don't properly resolve _all_ possible group memberships.
  If a user is a member of both local and NIS groups, we sometimes lose some
  of the membership info from NIS. (Reported by: Thorsten Kukuk
  <kukuk@uni-paderborn.de>)

- Make NIS +groupname overrides actually work the way the SunOS group(5)
  man page says they should (make them work for all cases: getgrent(),
  getgrnam() and getgrgid()).

- When not compiled with -DYP, grscan() should ignore entries that
  begin with a '+'. When compiled _with_ -DYP, grscan() should ignore
  +groupname entries that don't refer to real NIS groups.

- Remove redundant redeclaration of fgets(), strsep() and index() inside
  grscan(). We already #include all the right header files for these.

Note: -groupname exclusion as specified in the Sun documentation still
isn't supported. This'll be a 2.2 addition. Right now I just want this
stuff to work.
