jdolecek 382f8f9883 if emulation uses elf32_copyargs(), it shouldn't use it's own idea
of how many AUX arguments are actually passed

this fixes PR kern/20423 by Shingo WATANABE

jdolecek 555659c55c there is single emul_irix now
use irix_n32_setregs for the IRIX n32 execsw entry

jdolecek cee43b67cc add generic linux compat ELF copyargs function
this gives:
* linux sysconf(_SC_CLK_TCK) gives correct value for linux binaries (hz)
  even if hz != 100
* glibc gets proper information on real/effective uid and enables
  secure mode for suid binaries

g/c LINUX_COPYARGS_FUNCTION, replaced by linux ELF copyargs function

eeh 45a9507815 Native 32-bit and 32-bit emulation are mutually exclusive. We should not
even try to execute 32-bit binaries as native on a 64-bit kernel.

rafal 8fcad97302 Fix up linux a.out compat entry after move of emul-related sysctl handler
to struct emul.

jdolecek ebd670f0bc move emulation-specific sysctl hook from struct execsw to struct emul,
where it belongs
2002-04-02 20:19:59 +00:00
jdolecek 943f2b4f8a make COMPAT_11 or COMPAT_12 imply EXEC_ELF_NOTELESSS
use #if for the execsw entries, to allow 'options EXEC_ELF_NOTELESS=0'
  to override this

This addresses kern/13520 and kern/14409 by Matthew Green.

manu 89e46d8a99 Reworked the o32/n32 matching scheme. IRIX uses some e_flags in the ELF
header to distinguish between o32, n32 and n64 ABIs. We now use this.
This suppress the need of the mips_option test, which had some fake positive.
This also removes the mandatory ordering of n32 vs o32 in the exec switch
(exec_conf.c)
2002-02-21 21:53:00 +00:00
manu 4398be0cfc Added code to correctly match and launch o32 and n32 IRIX binaires (note that
there is n support yet in the kernel for running n32 binaries)

thorpej 21df9c4a6e Switch ELF emulations to ELF core files (except for netbsd32 and svr4-32). 2002-01-04 06:47:46 +00:00
thorpej 205c159f0e Make the coredump routine exec-format/emulation specific. Split
out traditional NetBSD coredump routines into core_netbsd.c and
netbsd32_core.c (for COMPAT_NETBSD32).

jdolecek ef8abe0767 Make the setregs hook emulation-specific, rather than executable
format specific.
Struct emul has a e_setregs hook back, which points to emulation-specific
setregs function. es_setregs of struct execsw now only points to
optional executable-specific setup function (this is only used for
ECOFF).

christos 32a9a52549 add mach/macho exec struct 2001-07-14 02:06:34 +00:00
jdolecek 3fd1ca0fc9 Do not include the ELF 'catch all' entry in execsw[] by default, which
used to make ELF binaries unmatched by any signature check to be run under
NetBSD 'emulation'. This causes problems like kern/12253.
The old behaviour is available with option EXEC_ELF_CATCHALL.

lukem 6cb5e77db5 remove use of gcc syntax for designated initialisers when initialising
unions `union_elem: ...', and use c99 syntax `.union_elem = ...' only
where necessary.
in this case, there's no need to tag elf_probe_func because that's the
first union element, and therefore, the implicit case. only specifically
mention ecoff_probe_func where necessary.

if we decide to not use this c99 feature for now, at least there's now
less stuff to rip out.

itojun 6c7e531e99 make COMPAT_OSF1 to compile. not tested (could someone review?). 2000-11-22 03:48:33 +00:00
jdolecek baae0324b9 restructure struct emul and execsw, in preparation to make emulations LKMable:
* move all exec-type specific information from struct emul to execsw[] and
  provide single struct emul per emulation
* elf:
  - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
    per emulation and contains pointer to respective probe function
  - interp is allocated via MALLOC() rather than on stack
  - elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
  to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
  emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
  part of appropriate execsw[] entry
* constify couple of structures

kleink 522cbf0248 Update to match new SVR4-style definition names in <sys/exec_elf.h>. 1999-10-25 13:55:06 +00:00
itojun 65363da25e Merge in NetBSD/sh3 from cvs.kame.net repository.
Tree structure:
- sys/arch/sh3: sh3 generic code
	As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)

Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
