perry 275d1554aa Abolition of bcopy, ovbcopy, bcmp, and bzero, phase one.
bcopy(x, y, z) ->  memcpy(y, x, z)
ovbcopy(x, y, z) -> memmove(y, x, z)
   bcmp(x, y, z) ->  memcmp(x, y, z)
  bzero(x, y)    ->  memset(x, 0, y)

to match the new uio_resid type.

mrg d90485202c - add defopt's for UVM, UVMHIST and PMAP_NEW.
- remove unnecessary UVMHIST_DECL's.
1998-02-10 14:08:44 +00:00
mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

enami 74a36a05ae No longer needs to include sys/shm.h. 1998-01-01 02:43:18 +00:00
thorpej a322314f51 Split out the code that prepares a VM space for exec into a new
vmspace_exec() function.

mycroft 16a8787248 Fix execve(2) and *setregs() interfaces so emulations can set registers in a
more correct way.  (See tech-kern.)
1997-09-11 23:01:44 +00:00
mycroft e3f99a9397 Pass the vnode type to vaccess(), and use it when checking VEXEC. Make sure
that the mode bits passed to vaccess() and returned by foo_getattr() contain
only permission bits.
1997-05-08 16:19:43 +00:00
mycroft d7f33c5e60 va_mode contains stat bits. Use S_IS[UG]ID rather than VS[UG]ID. 1997-05-08 10:19:10 +00:00
mycroft b34794e10f Do not return success when checking for execute permission by super-user and no
execute bits are set.  Also, this test is no longer needed in execve(2).
1997-04-23 20:18:16 +00:00
kleink cb9c71d716 Back out last change: just return EACCESS for any non-VREG file.
Fixes PR/3472 from Matthias Pfaller.
1997-04-10 19:45:40 +00:00
mycroft e01c3bbe05 Return EISDIR for directories, not EACCES. 1997-03-14 06:12:11 +00:00

cgd e7af2a8237 * catch up with system call argument type fixups/const poisoning.
* Fix arguments to various copyin()/copyout() invocations, to avoid
  gratuitous casts.
* Some KNF formatting fixes
1996-12-22 10:21:06 +00:00
cgd 3b34cba879 exec vnode locking protocol changes: in a nutshell, don't keep vnodes
locked for any longer than we have to.
1996-09-30 23:18:43 +00:00
cgd 2f42e5b8ed fix some typos and clean up some comments. 1996-09-26 23:34:46 +00:00

thorpej 60024eb978 Make system calls conform to a standard prototype and bring those
prototypes into scope.
1995-09-19 21:40:36 +00:00
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.
1995-07-19 15:19:08 +00:00
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.
1995-05-01 22:36:45 +00:00
christos 3d1b06ab09 - new copyargs routine.
- use emul_xxx
- deprecate nsysent; use constant SYS_MAXSYSCALL instead.
- deprecate ep_setup
- call sendsig and setregs indirectly.
1995-04-22 19:42:47 +00:00
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.
1995-04-07 22:33:23 +00:00

mycroft 974e9ba226 Fix typo in last change. 1994-02-12 07:19:11 +00:00
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.

keep arg buffer around for later use
canonicalize all #includes.

cgd dde22728d4 drag changes down from magnum 1993-11-15 10:21:08 +00:00
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.
1993-09-05 01:33:35 +00:00
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>.

#!/bin/sh

EOF

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...
1993-08-31 01:46:36 +00:00
cgd 2680a043c7 general cleanup (get close to KNF), and remove a few fuzzies
in preparation for The Grand Re-rewriting.
1993-07-28 04:08:27 +00:00
cgd c0334ef92c break args structs out, into syscallname_args structs, so gcc2 doesn't
whine so much.
1993-07-13 22:13:15 +00:00
brezak b5236e7d0f Roundup stack len to naturally aligned address. This fixes emacs aborting due to an odd address in alloca'ed memory. 1993-07-10 02:07:48 +00:00
brezak 31d24dc82e Ignore the flags field in midmag. 1993-07-08 16:48:18 +00:00

cgd b21025e4f3 call setregs with a retval, too, so the hp300 & mac, and more works. 1993-07-04 09:48:29 +00:00
andrew 0e6cb953ea ANSIfications - removed all implicit function return types and argument
definitions.  Ensured that all files include "systm.h" to gain access to
general prototypes.  Casts where necessary.

cgd c8bdad0560 convert magic numbers to network byte order, and attendent changes 1993-06-18 06:49:30 +00:00
cgd 24fe3e4563 fixed bug where extra spaces at the end of a shell name would
cause shell scripts to be executed incorrectly.  shells would
receive an *empty* arg for name of script, open it, the kernel
would say "oh, that's ." or something similar, and the results
would be interesting...  found, diagnosed, and killed by me.

cgd eb4c4de385 replace exec.
new one based on one by Wolfgang Solfrank, but majorly hacked
(as it: it didn't have a chance in hell of working, before; didn't
even bother copying out argc, for one...)
1993-05-31 01:44:55 +00:00
