Add -fPIC to CFLAGS and -specs=hardened-build-ld to LDFLAGS.
This enables package build as Position Independent Executables (PIE)
to protect against "return-to-text" attacks. This belongs to the
feature of Address Space Layout Randomisation (ASLR), which is
implemented by the kernel and the ELF loader by randomising the
location of memory allocations. This makes memory addresses harder
to predict when an attacker is attempting a memory-corruption exploit.
You can disable this per package by adding PKG_ASLR_PIE:=0 in the package
Makefile.

Subject: ELF/BFD: Limit `_bfd_elf_link_renumber_dynsyms' call in section GC
Consistently call `_bfd_elf_link_renumber_dynsyms' only if linking a
dynamic binary, complementing code in `bfd_elf_size_dynsym_hash_dynstr'
and commit ccabcbe51e85 ("New attempt at fixing MIPS --gc-sections et
al."), <https://sourceware.org/ml/binutils/2005-08/msg00258.html>.
bfd/
* elflink.c (elf_gc_sweep): Only call
`_bfd_elf_link_renumber_dynsyms' if dynamic sections have been
created.

Subject: PR ld/21334: Always call `_bfd_elf_link_renumber_dynsyms' if required
Complement commit e17b0c351f0b ("MIPS/BFD: Respect the ELF gABI dynamic
symbol table sort requirement") and correct an inconsistency in dynamic
symbol accounting data causing an assertion failure in the MIPS backend:
ld: BFD (GNU Binutils) 2.28.51.20170330 assertion fail
../../binutils-gdb/bfd/elfxx-mips.c:3860
in the course of making a GOT entry in a static binary to satisfy a GOT
relocation present in input, due to the local dynamic symbol count not
having been established.
To do so let backends request `_bfd_elf_link_renumber_dynsyms' to be
always called, rather than where a dynamic binary is linked only, and
then make this request in the MIPS backend.
bfd/
PR ld/21334

member.

gcc/musl: rework SSP-support
Make musl provide libssp_nonshared.a and make GCC link it unconditionally
if musl is used. This should be a no-op if SSP is disabled and seems to be
the only reliable way of dealing with SSP over all packages due to the mess
that is linkerflags handling in packages.

commit b050f87d13b5dc7ed82feb9a90f4529de58bdf25
Author: Felix Fietkau <nbd@openwrt.org>
Date: Wed Feb 19 19:20:10 2014 +0000
gcc: prevent the use of LDRD/STRD on ARMv5TE
These instructions are for 64-bit load/store. On ARMv5TE, the CPU
requires addresses to be aligned to 64-bit. When misaligned, behavior is
undefined (effectively either loads the same word twice on LDRD, or
corrupts surrounding memory on STRD).
On ARMv6 and newer, unaligned access is safe.
Removing these instructions for ARMv5TE is necessary, because GCC
ignores alignment information in pointers and does unsafe optimizations
that have shown up as bugs in various places.

Date: Fri Apr 5 12:36:06 2013 +0000
toolchain/gcc: .init and .fini need to pick one ISA
The .init and .fini sections are built by concatenating code
fragments. Putting mips16 code in the middle of a mips32 code block
doesn't work. Make gcc built the magic crt stuff in no-mips16 mode.
This is specific to 4.6-linaro but is probably portable to other gcc
flavors. Adding this to the t-libgcc-mips16 makefile fragment is a
hack not suitable for pushing upstream, but there is no mips/t-linux
or mips/t-uclibc and I am not going to touch gcc/configure for two
lines.

commit 99368862e44740ff4fd33760893f04e14f9dbdf1
Author: Felix Fietkau <nbd@openwrt.org>
Date: Tue Jul 31 00:52:27 2007 +0000
This patch brings over a few features from MirBSD:
Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
SVN-Revision: 8256
This patch brings over a feature from MirBSD:
* -fhonour-copts
If this option is not given, it's warned (depending
on environment variables). This is to catch errors
of misbuilt packages which override CFLAGS themselves.
* -Werror-maybe-reset
Has the effect of -Wno-error if GCC_NO_WERROR is
set and not '0', a no-operation otherwise. This is
to be able to use -Werror in "make" but prevent
GNU autoconf generated configure scripts from
freaking out.
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
with copyright assignment to the FSF in effect.

gcc: don't clobber stamp-bits with a symlink to itself
Several versions of gcc have an issue in libstdc++v3 where the build may
clobber stamp-bits with a link to itself. This doesn't manifest itself
on all systems. On several Ubuntu systems, this doesn't appear to be a
problem, but it is an issue on Fedora 16 systems.
To fix the issue, we'll simply filter out stamp-bits from the symlinks
to be generated.
Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
there.

Date: Thu, 22 Jun 2017 22:04:28 +0200
Subject: [PATCH] Add additional uapi guards for Linux kernel header files
With Linux kernel 4.15 it will be possible to guard more parts of the
Linux header files from a libc. Make use of this in musl to guard all
the structures and other definitions from the Linux header files which
are also defined by the header files provided by musl. This will make
musl compile with the unmodified Linux kernel user space headers.
This extends the definitions done in commit 04983f227238 ("make
netinet/in.h suppress clashing definitions from kernel headers")
The needed patches were recently accepted for Linux 4.15:
