christos f2a8a907b4 simplify an expression. 2001-07-29 21:24:23 +00:00
christos 3e1e7a68e5 adjust to the new copyargs footprint 2001-07-29 21:22:58 +00:00
christos 2c913b0983 Fix problem reported by Greg Woods, with ld -n generated binaries.
Now if the requested alignment of the psection is less than PAGE_SIZE
we use readvn, not pagedvn and we don't adjust sizes.

christos 69f5770270 - add exec_read_from and make exec_elf32 use it.
- add a macho probe function

jdolecek 27a5a43c04 In the check_header() function, bump the number of allowed section headers
to 512. Apparently, there are ELF binaries with more than 128 section
headers - an example is one of Linux Word Perfect 8 utilities.

This fixes kern/12455 by Mark Davies.

eeh e938c4e842 *NEVER* cast a reference parameter (unless you're using C++). 2001-02-04 19:12:09 +00:00
mycroft b29180b2ff Tighten up the ELF signature checks, and actually look for the ABI tag added
in newer glibc versions.

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.

mrg 51858ad725 backout part of execsw/LKM changes: netbsd_elf32_signature() is used by
the compat/netbsd32 code so de-static it again.
2000-11-28 13:10:41 +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

fvdl ee489171ee Make previous change in interpreter entry point calculation dependant on
a 'mips' define. XXX

Just a temporary patch to get things going again for Linux ELF binaries,
needs to be solved properly.

jonathan bbcd2bb1ef Elf32 fixes for mips shared libraries:
* handle interpreters with nonzero virtual address of entry-point:
   subtract p_vaddr from computed entrypoint, as the mips elf exec did.

 * Add #ifdef ELF_INTERP_NON_RELOCATABLE/#endif around the code
   that tries to choose a `good' address at which to load an interpreter,
   if none was set by the emul probe  function.
   (the address chosen could be improved to avoid  fragmenting the
    process virtual address space).

 * define ELF_INTERP_NON_RELOCATABLE in machine/elf_machdep.h for mips CPUs,
   which currently use a GNU-derived ld.so.

ELF_INTERP_NON_RELOCATABLE is not necessary for native NetBSD/alpha ELF
binaries. It may be required for GNU-derived ELF dynamic loaders (Linux/i386?)

cgd 0e4ddf059b deal more sanely with ELF binaries with only a single program header
section.  Patch come up with by Bob Baron <rvb+@cs.cmu.edu> and myself.
This entire bit of code (the code which sets daddr/dsize and taddr/tsize)
is very bogus, but it's not clear what the 'right' way to fix it is
and this patch fixes a problem preventing some ELF executables from
being run.
1996-10-13 22:54:52 +00:00
cgd 4431ea58a9 replace ELF_ALIGN with ELF_TRUNC (round to lower alignment boundary) and
ELF_ROUND (round to higher alignment boundary), and use them properly.
Also, change a bit of code in elf_load_psection to use the next ELF_ROUND
macro.  This fixes a bug found by Robert Baron <rvb+@cs.cmu.edu> where
elf_load_psection, if given a properly aligned address at which to load
the section, would round actually load it at the next highest alignment
boundary.
