configure: Implement --enable-host-pie
[ This is my third attempt to add this configure option. The first
version was approved but it came too late in the development cycle.
The second version was also approved, but I had to revert it:
<https://gcc.gnu.org/pipermail/gcc-patches/2022-November/607082.html>.
I've fixed the problem (by moving $(PICFLAG) from INTERNAL_CFLAGS to
ALL_COMPILERFLAGS). Another change is that since r13-4536 I no longer
need to touch Makefile.def, so this patch is simplified. ]
This patch implements the --enable-host-pie configure option which
makes the compiler executables PIE. This can be used to enhance
protection against ROP attacks, and can be viewed as part of a wider
trend to harden binaries.
It is similar to the option --enable-host-shared, except that --e-h-s
won't add -shared to the linker flags whereas --e-h-p will add -pie.
It is different from --enable-default-pie because that option just
adds an implicit -fPIE/-pie when the compiler is invoked, but the
compiler itself isn't PIE.
Since r12-5768-gfe7c3ecf, PCH works well with PIE, so there are no PCH
regressions.
When building the compiler, the build process may use various in-tree
libraries; these need to be built with -fPIE so that it's possible to
use them when building a PIE. For instance, when --with-included-gettext
is in effect, intl object files must be compiled with -fPIE. Similarly,
when building in-tree gmp, isl, mpfr and mpc, they must be compiled with
-fPIE.
With this patch and --enable-host-pie used to configure gcc:

on a Debian system where the system gcc was configured with

configure: Implement --enable-host-bind-now
As promised in the --enable-host-pie patch, this patch adds another
configure option, --enable-host-bind-now, which adds -z now when linking
the compiler executables in order to extend hardening. BIND_NOW with RELRO
allows the GOT to be marked RO; this prevents GOT modification attacks.
This option does not affect linking of target libraries; you can use
LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now to enable RELRO/BIND_NOW.
With this patch:

trend to harden binaries.
It is similar to the option --enable-host-shared, except that --e-h-s
won't add -shared to the linker flags whereas --e-h-p will add -pie.
It is different from --enable-default-pie because that option just
adds an implicit -fPIE/-pie when the compiler is invoked, but the
compiler itself isn't PIE.
Since r12-5768-gfe7c3ecf, PCH works well with PIE, so there are no PCH
regressions.
When building the compiler, the build process may use various in-tree
libraries; these need to be built with -fPIE so that it's possible to
use them when building a PIE. For instance, when --with-included-gettext
is in effect, intl object files must be compiled with -fPIE. Similarly,
when building in-tree gmp, isl, mpfr and mpc, they must be compiled with
-fPIE.
With this patch and --enable-host-pie used to configure gcc:

I plan to add an option to link with -Wl,-z,now.
Bootstrapped on x86_64-pc-linux-gnu with --with-included-gettext
--enable-host-pie as well as without --enable-host-pie. Also tested
on a Debian system where the system gcc was configured with
--enable-default-pie.

configure: Implement --enable-host-bind-now
As promised in the --enable-host-pie patch, this patch adds another
configure option, --enable-host-bind-now, which adds -z now when linking
the compiler executables in order to extend hardening. BIND_NOW with RELRO
allows the GOT to be marked RO; this prevents GOT modification attacks.
This option does not affect linking of target libraries; you can use
LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now to enable RELRO/BIND_NOW.
With this patch:

configure: Implement --enable-host-pie
[ This is my third attempt to add this configure option. The first
version was approved but it came too late in the development cycle.
The second version was also approved, but I had to revert it:
<https://gcc.gnu.org/pipermail/gcc-patches/2022-November/607082.html>.
I've fixed the problem (by moving $(PICFLAG) from INTERNAL_CFLAGS to
ALL_COMPILERFLAGS). Another change is that since r13-4536 I no longer
need to touch Makefile.def, so this patch is simplified. ]
This patch implements the --enable-host-pie configure option which
makes the compiler executables PIE. This can be used to enhance
protection against ROP attacks, and can be viewed as part of a wider
trend to harden binaries.
It is similar to the option --enable-host-shared, except that --e-h-s
won't add -shared to the linker flags whereas --e-h-p will add -pie.
It is different from --enable-default-pie because that option just
adds an implicit -fPIE/-pie when the compiler is invoked, but the
compiler itself isn't PIE.
Since r12-5768-gfe7c3ecf, PCH works well with PIE, so there are no PCH
regressions.
When building the compiler, the build process may use various in-tree
libraries; these need to be built with -fPIE so that it's possible to
use them when building a PIE. For instance, when --with-included-gettext
is in effect, intl object files must be compiled with -fPIE. Similarly,
when building in-tree gmp, isl, mpfr and mpc, they must be compiled with
-fPIE.
With this patch and --enable-host-pie used to configure gcc:

--enable-host-pie build host code as PIE

configure: Implement --enable-host-bind-now
As promised in the --enable-host-pie patch, this patch adds another
configure option, --enable-host-bind-now, which adds -z now when linking
the compiler executables in order to extend hardening. BIND_NOW with RELRO
allows the GOT to be marked RO; this prevents GOT modification attacks.
This option does not affect linking of target libraries; you can use
LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now to enable RELRO/BIND_NOW.

Some influential environment variables:
|
|
|
|
|
CXX C++ compiler command
|
|
|
|
|
CXXFLAGS C++ compiler flags
|
|
|
|
|
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
|
|
|
|
|
nonstandard directory <lib dir>
|
|
|
|
|
LIBS libraries to pass to the linker, e.g. -l<library>
|
|
|
|
|
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
|
|
|
|
|
you have headers in a nonstandard directory <include dir>

configure: Implement --enable-host-pie
[ This is my third attempt to add this configure option. The first
version was approved but it came too late in the development cycle.
The second version was also approved, but I had to revert it:
<https://gcc.gnu.org/pipermail/gcc-patches/2022-November/607082.html>.
I've fixed the problem (by moving $(PICFLAG) from INTERNAL_CFLAGS to
ALL_COMPILERFLAGS). Another change is that since r13-4536 I no longer
need to touch Makefile.def, so this patch is simplified. ]
This patch implements the --enable-host-pie configure option which
makes the compiler executables PIE. This can be used to enhance
protection against ROP attacks, and can be viewed as part of a wider
trend to harden binaries.
It is similar to the option --enable-host-shared, except that --e-h-s
won't add -shared to the linker flags whereas --e-h-p will add -pie.
It is different from --enable-default-pie because that option just
adds an implicit -fPIE/-pie when the compiler is invoked, but the
compiler itself isn't PIE.
Since r12-5768-gfe7c3ecf, PCH works well with PIE, so there are no PCH
regressions.
When building the compiler, the build process may use various in-tree
libraries; these need to be built with -fPIE so that it's possible to
use them when building a PIE. For instance, when --with-included-gettext
is in effect, intl object files must be compiled with -fPIE. Similarly,
when building in-tree gmp, isl, mpfr and mpc, they must be compiled with
-fPIE.
With this patch and --enable-host-pie used to configure gcc:

Bootstrapped on x86_64-pc-linux-gnu with --with-included-gettext

on a Debian system where the system gcc was configured with
--enable-default-pie.

configure: Implement --enable-host-pie
[ This is my third attempt to add this configure option. The first
version was approved but it came too late in the development cycle.
The second version was also approved, but I had to revert it:
<https://gcc.gnu.org/pipermail/gcc-patches/2022-November/607082.html>.
I've fixed the problem (by moving $(PICFLAG) from INTERNAL_CFLAGS to
ALL_COMPILERFLAGS). Another change is that since r13-4536 I no longer
need to touch Makefile.def, so this patch is simplified. ]
This patch implements the --enable-host-pie configure option which
makes the compiler executables PIE. This can be used to enhance
protection against ROP attacks, and can be viewed as part of a wider
trend to harden binaries.
It is similar to the option --enable-host-shared, except that --e-h-s
won't add -shared to the linker flags whereas --e-h-p will add -pie.
It is different from --enable-default-pie because that option just
adds an implicit -fPIE/-pie when the compiler is invoked, but the
compiler itself isn't PIE.
Since r12-5768-gfe7c3ecf, PCH works well with PIE, so there are no PCH
regressions.
When building the compiler, the build process may use various in-tree
libraries; these need to be built with -fPIE so that it's possible to
use them when building a PIE. For instance, when --with-included-gettext
is in effect, intl object files must be compiled with -fPIE. Similarly,
when building in-tree gmp, isl, mpfr and mpc, they must be compiled with
-fPIE.
With this patch and --enable-host-pie used to configure gcc:

configure: Implement --enable-host-bind-now
As promised in the --enable-host-pie patch, this patch adds another
configure option, --enable-host-bind-now, which adds -z now when linking
the compiler executables in order to extend hardening. BIND_NOW with RELRO
allows the GOT to be marked RO; this prevents GOT modification attacks.
This option does not affect linking of target libraries; you can use
LDFLAGS_FOR_TARGET=-Wl,-z,relro,-z,now to enable RELRO/BIND_NOW.
