christos 7de0fcfd12 Add KTR_EMUL to indicate a switch between syscall emulations.
Currently this record is emitted only on exec. Maybe it should
be emitted on ktrace() attach too.

mycroft bfd22ffde8 Generate the new ps_strings format. 1995-05-16 14:19:03 +00:00
cgd 2581c66077 remember first error code (if any) that's different than ENOEXEC.
Not perfect, but there's no perfect solution to the "multiple interesting
error codes" problem.

christos 3d1b06ab09 - new copyargs routine.
- use emul_xxx
- deprecate nsysent; use constant SYS_MAXSYSCALL instead.
- deprecate ep_setup
- call sendsig and setregs indirectly.

mycroft c75f9f2e07 Change `fdclose' to `fdrelease', to avoid confusion with device interfaces. 1995-04-10 18:27:59 +00:00
fvdl 366ba9b889 Use sigcode fields in package structure. This seems to be the cleanest
way to deal with seperate trampoline code for emulation of other OSs,
it avoids having to clutter up kern_exec.c any further.

cgd 3a46cb73c6 ditto on the last; weird failure modes are the cause of the day. 1994-02-12 07:02:34 +00:00
cgd 64517d6f7f don't forget to deallocate vmcmds if exec fails bounds checks.
thanks to charles for pointing it out.

cgd 13ca4d98c7 it's correct to return EACCES if FS is mounted MNT_NOEXEC. 1993-10-26 01:42:56 +00:00
cgd c7582cbd4f use copyinstr rather than strcpy to copy in the saved shell-script
name from userland.  From Markus Wild, mw@lamp
1993-10-26 00:32:29 +00:00
cgd a84055b552 use the ALIGN macro to align the stack, rather than rounding up
by a (char *).  the former is safe, even on strange machines
(read: sparc).
1993-10-06 07:27:58 +00:00
cgd 83aeee1bc0 there now exists an "exec switch". break the a.out code into another
module, and tidy up the interface so that other object formats are
more easily supportable.

cgd 491d6b4b9d fix problem where exec would lose on shell scripts with symlinks in
their names.  fix from "James W. Dolter" <jdolter@sawtooth.eecs.umich.edu>.
test script:

#!/bin/csh
mkdir /tmp/foodir
cat > /tmp/foodir/testscript <<EOF
#!/bin/sh
echo "Executing script \$1"
EOF
chmod 755 /tmp/foodir/testscript
(cd /tmp ; ln -s foodir foosym)
echo "Trying full path (w/o symlink) to /tmp/foodir/testscript"
/tmp/foodir/testscript "with out symlink"
echo "Trying full path (w/ symlink) to /tmp/foosym/testscript"
/tmp/foosym/testscript "with symlink"
echo "End of Test"

cgd d365662684 ok, initialize that errno, to make theo and gcc2 happy... 1993-08-31 01:52:34 +00:00
cgd 518f7c78d6 a program being exec'd *must* cause *some* exec commands to be invoked;
if it doesn't there's a problem in the kernel, because a program
with no exec commands run will have no address space except the stack,
and i don't think it's valid to have a "run from stack only" exec type,
so panic.  if need for that case comes up later, it can be changed...

cgd 2680a043c7 general cleanup (get close to KNF), and remove a few fuzzies
in preparation for The Grand Re-rewriting.
