- Split 4.3BSD ifioctl stuff into its own file.
- Remove some ifdefs that include small fragments of vfs compat code
which are difficult to relocate elsewhere.
compatibility with the older ioctls. This avoids stack smashing and
abuse of "struct sockaddr" when ioctls placed "struct sockaddr_foo's" that
were longer than "struct sockaddr".
XXX: Some of the emulations might be broken; I tried to add code for
them but I did not test them.
sys_stat() and friends, instead use do_sys_stat() and do_sys_fstat()
that write the answer into a kernel buffer (on stack) that can be
converted to the correct form and written the userspace.
I've test compiled a few kernels, and tested i386 netbsd1.6 ls.
Given I think I've fixed some bugs, it might be 50-50 with new ones.
EPROTONOSUPPORT instead of EAFNOSUPPORT.
from pavel@ with a little bit of clean up from myself.
XXX: netbsd32 (and perhaps other emulations) should be able
XXX: to call the standard socket calls for this i think, but
XXX: revisit this at another time.
compat/common, so that they can be shared by several emulations, and use
them for Darwin.
This removes the ugly dependance on FreeBSD freebsd_file.c for COMPAT_DARWIN
directories and use .PATH to lookup the source files.
(Formerly, the libs were built from the source dirs, with MAKEOBJDIR
set to the compilation directory.)
This solves 2 problems:
-"mkdep" and "make" are now consistent about the file lookup, this fixes
bad interactions with amd reported in PR bin/7374 (Arne Juul) and
lossage reported by Andrew Gillham ("obj" dirs and relative paths still
don't work well together)
-kernel compile trees can be moved around without forcing a new
"make depend" - fixing PR kern/4021 by Martin Husemann
to be of type size_t; since this imposes an interface change on the Alpha
(sizeof(int) != sizeof(size_t)), allocate a new system call number and make
the previous version a compatibility system call.
a boot string for firmware that can do this, such as the SPARC and
the sun3 models. It is currently silently ignored on all other
hardware now, however. The MD function "boot()" has been changed to
also take a char *.
This is used by the i386, hp300 and mac68k ports.
- Added exec_aout_prep_oldomagic, and exec_aout_prep_oldnmagic
These are just copies of the respective prep functions from
kern_exec.c with text address starting at 0. Maybe a better fix
is to pass the starting address as a third argument so we don't
duplicate code, but this could be the next pass since the functions
are used in many places. These functions are used for BSDI binaries.
- Created compat_util.c and compat_util.h to be used by the compatibility
modules, so they don't duplicate the same code.
- Added prototypes to the stackgap allocation routines.
