include path: the normal header files now include the "SSP" ones (which one
should note are not really named right: SSP and FORTIFY_SOURCE are independent
features).
Disable USE_SSP on targets where the compiler doesn't support it at all
(mips, alpha) or it's known broken (sh3). But enable FORTIFY_SOURCE,
without SSP, on those platforms -- tested on mipsel.
(what other systems keep in libssp, we already have in libc) into libc
to match what other systems with FORTIFY_SOURCE do. Goodbye, libssp
dependency in libraries and executables. Discussed with christos and
mrg; Christos will merge the headers to get us the rest of the way to a
FORTIFY_SOURCE implementation that works as others' code expects.
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry. RedHat has
evidently built all "core system packages" with this option for some time.
This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.
This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros. Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.
Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.
where ${MAKEWRAPPERMACHINE} is the suffix XXX on the target's make
wrapper, nbmake-XXX.
Fixes toolchain/30673, "single arch host disklabel isn't enough".
set .OBJDIR so 'make -V .OBJDIR' doesn't need to read any makefiles.
Given how much cud-chewing make does in order to read a line, this
speeds things up significantly (the operation in hand).
make rules, nor reading Makefile.
It is rather a shame we can't stop .depend being parsed as well.
Quite possibly one could argue that nothing in .depend should affect the
output of 'make -V xxxx'.
Add .WAITs after beforeinstall and before afterinstall.
Remove the bogus dependency lines that someone must have added with the
vague hope they would cause the build to happen in the right order!
Since we have 'realinstall: proginstall scriptsinstall' stopping
'realinstall' running never has stopped 'proginstall' running.
Fixing this probably fixes a variety of problems, including, but not
restricted to 'install' in src/sys/arch/atari/stand/bootxx
(NB this particular file is untested due to other local changes)
- retire LIBDCK, LIBG2C and (long broken) USE_LIBSTDCXX
- in bsd.hostprog.mk's LIBSTDCPP -> LIBSTDCC
- add LIBSUPCXX
- don't default USE_LIBSTDCXX or USE_GCC4 since they are
not used in the tree any where
- same with USE_XF86_4; retire it
- remove _SUPCXX handling in bsd.prog.mk
