- remove unnecessary UVMHIST_DECL's.

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.  :-)

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
mrg 7de1b7c8eb only set P_SUGID once. 1997-01-07 10:41:02 +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

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

mycroft feb42498e3 If we abort, make sure to free ep_emul_arg. 1995-12-09 04:11:00 +00:00
mycroft 245f292fed Prefix names of system call implementation functions with `sys_'. 1995-10-07 06:25:19 +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.

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.

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.
