cgd 5d4cf83257 when loading interpreter: check its vnode type, check its mount point
for NOEXEC and NOSUID, and make sure the interpreter file is executable.
The mount point checks are done because, even though the interpreter
is not the program being 'executed', code from the interpreter is being
executed, and so the mount point's flags should be respected.

cgd cc06b3f10f Remove the implicit inclusion of EXEC_ELF32 when COMPAT_LINUX and/or
COMPAT_SVR4 is included.

cgd 3b34cba879 exec vnode locking protocol changes: in a nutshell, don't keep vnodes
locked for any longer than we have to.

cgd 6f5b5cefc7 make the check_header and load_file functions static 1996-09-30 23:02:14 +00:00
cgd 0e097578a2 add and use a machine-dependent header, which currently defines some
macros to use to remove #ifdefs from the machine ID case check.
Eventually, these headers will contain other information, e.g.
machine-dependent relocation information, etc.

cgd 79bd41b179 add support and reorganize for 64-bit ELF, included by EXEC_ELF64
option.  (Also, make EXEC_ELF32 option a way to explicitly include
32-bit ELF support.)

christos e2e0f65050 Merge pagedvn changes from OpenBSD and added mips defines. Also added
ELF_MAP_PAGE_ZERO define. The entry point computation is different than
the one OpenBSD uses.

christos 306987eb37 - Pass the Elf exec header in the emulation dependent probe functions.
- remove static from elf_read_from().

fvdl d6b5a89f90 Use a default, 'safe' address to map the loader to in case the an emulation-
specific probe function did not specify it. It picks the same address
as mmap() does for a non-fixed map at address 0. See also the comment
around a similar line of code in vm/vm_mmap.c.

fvdl 961c294fd5 * Don't rely on the protection bits of segments anymore to decide whether
it's text or data; use the entry point instead (this solves some trouble
  with ELF executables with strange permissions)
* Incorporate some fixes from r_friedl@informatik.uni-kl.de sent to
  netbsd-bugs a while ago
