lukem dab6ef8b56 add RCSIDs (including regeneration of files as appropriate) 2001-11-13 02:07:52 +00:00
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 0f380fac15 Add an e_trapsignal member to struct emul, so that emulated processes can
send the appropriate signal depending on the trap type.

manu ff5ce5bd93 Removed obsoletes EMUL_NO_BSD_ASYNCIO_PIPE and EMUL_NO_SIGIO_ON_READ flags.
Async I/O OS specifities should now handled in OS specific code. Linux
has been done, but other emulation should be handled. See case LINUX_F_SETFL
in sys/compat/linux/common/linux_file.c:linux_sys_fcntl() for more details.

The data that has been collected yet:

manu 7e6929fe90 Changed EMUL_BSD_ASYNCIO_PIPE to EMUL_NO_BSD_ASYNCIO_PIPE, so that
the native emulation (NetBSD) does not have a flag.

eeh a72ee87980 Add support for 64-bit SVR4 (Solaris 8) binaries. 2001-02-21 23:53:00 +00:00
mycroft f495cd9dc6 Introduce 2 new flags in types.h:
* __HAVE_SYSCALL_INTERN.  If this is defined, e_syscall is replaced by
  e_syscall_intern, which is called at key places in the kernel.  This can be
  used to set a MD syscall handler pointer.  This obsoletes and replaces the
  *_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL.  If this is defined, certain (deprecated) elements in
  struct emul are omitted.

jdolecek 8f9b01eba1 prototype svr4_syscall() (only) in compat/svr4/svr4_exec.c 2000-12-09 12:44:26 +00:00
jdolecek a6ca890142 always fill in e_syscall in respective emul_*; if the emulation doesn't
have it's own separated *_syscall() function, use syscall()
2000-12-09 12:38:23 +00:00
mycroft 77b46f5749 Oops; missed a critical #include. 2000-12-09 06:25:03 +00:00
mycroft 95bdfed457 Add hook for a separate svr4_syscall(). 2000-12-09 06:20:17 +00:00
jdolecek 2ff42428df put elf32 specific code from svr4_exec.c to separate file svr4_exec_elf32.c 2000-12-01 19:26:26 +00:00
jdolecek 01040d97a2 add e_path (emulation path) to struct emul, which replaces emulation-specific
*_emul_path variables

change macros CHECK_ALT_{CREAT|EXIST} to use that, 'root' doesn't need
to be passed explicitly any more and *_CHECK_ALT_{CREAT|EXIST} are removed
change explicit emul_find() calls in probe functions to get the emulation
path from the checked exec switch entry's emulation

remove no longer needed header files

add e_flags and e_syscall to struct emul; these are unsed and empty for now
2000-12-01 12:28:30 +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

christos e1f16dd0c9 Assign copyrights to TNF; tv has copyrights on the remaining files...
It would be nice if he changed them (hint, hint)

cgd 912e6fef44 include <sys/exec.h> rather than <machine/exec.h> 1996-10-07 21:47:33 +00:00
cgd 65148dea43 kill (re)definitions of EXEC_ELF32. They're no longer necessary
(because of the EXEC_* option changes), and now cause warnings.
1996-10-03 05:02:05 +00:00
cgd 7c3255776d slightly clean up some of the changes made when ELF64 support went in 1996-09-27 18:14:23 +00:00
cgd 9c3e274c7b adapt ELF-using compat code to use new ELF definitions/code. At this point,
these are restricted to 32-bit ELF, and should be severely cleaned.

christos 5d27db0882 Pass the elf exec header in the probe function. 1996-06-13 18:33:54 +00:00
christos a4e2f7532a - Added msgsys, shmsys and semsys... MITSHM needs shmsys, so X applications
that used that would fail.
- Propagated all the fixes from the fully prototyped kernel.

christos d0169ce44a Use compat_util.[ch] 1995-06-24 20:29:17 +00:00
fvdl 4a10f838e7 Changed to use generic ELF code from kern/exec_elf.c (which was taken
from the svr4 exec code plus the linux compat mods)
1995-06-22 21:32:57 +00:00
fvdl a22d72bf4d * Always kill all vm_cmds before giving up on loading an executable
* Don't try to use auxiliary arguments with statically linked executables.
* Remove 'cannot find interpreter' uprintf, as other exec modules may
  succeed in running the binary after all, and then we don't want this message.
* Some linkers produce rw- for the data segment, not rwx.
* Remove a few debugging printfs

jtc 95ded74f58 Moved egid credential from cr_groups[0] to new field cr_gid. POSIX.1
requires that sgid executables and the setuid() syscall *not* change
the supplemental group list.

christos 44eef7c28b - added struct emul to all emulations.
- removed all setup functions.
- added copyargs() functions where needed.

christos ee05f066e8 1. siginfo stuff torn out from wait.h to be used by the MI portion of the code.
2. many termio, ioctl, sigaction fixes
3. better socket type emulation; still ticotsord [the loopback interface I
   guess] does not work properly on svr4 4.1.
4. new gettimeofday, fixed utssys..
5. rmdir and mkdir were swapped in syscalls.master
