- LINUX_GO_RT0_SIGNATURE for compat_linux is no longer enabled by default.
it is now defined in each arch same as the other *_SIGNATURE definitions.
- add new LINUX32_GO_RT0_SIGNATURE for compat_linux32, and is defined in amd64 and aarch64.

es_arglen is now in units of bytes, update the emulations accordingly.

branches: 1.12.6; 1.12.10; 1.12.14;
account for the 16 bytes of AT_RANDOM data in the stack setup. fixes PR 48518.
use cprng_strong32() instead of random(). add AT_RANDOM support for linux32.

branches: 1.11.2; 1.11.4;
define LINUX_DEBUGLINK_SIGNATURE for i386 too.
this allows linux ldd to work.

branches: 1.10.16; 1.10.20; 1.10.22;
LINUX_GCC_SIGNATURE also matches NetBSD/i386 ELF binaries, so disable it.

branches: 1.9.6; 1.9.8;
Remove clause 3 and 4 from TNF licenses

branches: 1.8.70; 1.8.72; 1.8.74;
merge ktrace-lwp.

branches: 1.7.16;
Hide prototype of linux_exec_setup_stack() inside #ifdef _KERNEL so
that sbin/sysctl will compile.

- GC all the setup_stack functions
- add one for linux/i386

branches: 1.5.6;
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
g/c alpha-specific linux ELF copyargs function and linux ELF defines

branches: 1.4.2;
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

Make the linux compatibilty code work on the alpha. (horay!) (at last!)
Two main changes:
Create a linux_elf64_copyargs that uses the linux specific LinuxAuxInfo
structure. This is only used on the alpha. i386 and m68k use the
standard elf copyargs function.

Since linux's approach to binary compatibilty is to look as much
like osf1 as possible, add all the osf1 syscalls that we have
implemented to the linux syscall table. This includes get/setsysinfo,
ported from FreeBSD.

In order for linux compat to work you must have COMPAT_OSF1, COMPAT_43,
COMPAT_09, COMPAT_12 and COMPAT_13 on also.

branches: 1.2.12;
Define LINUX_GCC_SIGNATURE.

Add linux i386 machine type.
