Hi everyone,
I'd like to announce a new subproject of Hardened Gentoo, Hardened musl
[1]. musl is a new C standard library, optimized for embedded systems.
It is "lightweight, fast, simple, free, and strives to be correct in the
sense of standards-conformance and safety." [2] Like its sister
subproject, Hardened uClibc [3], this project focuses on porting both
userland and kernel hardening to musl based systems for a variety of
architectures, treating musl as a drop in alternative to glibc. The
releases are not "embedded" in the sense that most userland utilities
are provided by busybox; rather, we make use of coreutils, util-linux,
and other typical GNU utilities that you'd find on any regular Gentoo
system.
The release images are stage3 tarballs built using catalyst and our
automation scripts [4]. Unlike the uClibc project where most packages
"just build", musl's adherence to standards means that many packages
need some minor patching. These are kept on our hardened-dev overlay in
the musl branch [5].
This is work in progress. The following table gives a brief summary of
the current state of affairs:
Arch Subarch ABI(s) Flavors Status
amd64 Generic default 64-bit hardened/vanilla stage3
arm armv7a eabi hardened/vanilla stage3
mips mips32r2 o32 vanilla <in progress>
mips mipsel3 o32 vanilla stage3
x86 i686 default 32-bit vanilla
stage3
These are available on the mirrors at ${MIRROR}/expiermental/${ARCH}/musl.
