From e6db002716c0c46fd73ebc258ada23edbf5c7d12 Mon Sep 17 00:00:00 2001 From: Zach van Rijn Date: Sat, 10 Dec 2022 11:32:48 -0600 Subject: Initial proof of concept. Currently, if you run this on a Linux box as an unprivileged user: $ ./bootstrap armv7 /some/scratch/directory you will end up with, completely from source: rootfs-armv7l-adelie-linux-musleabihf-preimage.tgz which is an armv7-native rootfs with all the tools that you need to build our distribution. (Substitute your favorite target). Work that remains to be done involves fixing "bootstrap.sh" in the packages.git repository, then plumbing that back into this project so that the complete process can be automated. --- binsub.c | 277 +++++++++++++++++++++ bootstrap | 763 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ setup-abuild | 362 +++++++++++++++++++++++++++ setup-packages | 13 + setup-preimage | 35 +++ 5 files changed, 1450 insertions(+) create mode 100644 binsub.c create mode 100755 bootstrap create mode 100755 setup-abuild create mode 100755 setup-packages create mode 100755 setup-preimage diff --git a/binsub.c b/binsub.c new file mode 100644 index 0000000..c66148c --- /dev/null +++ b/binsub.c @@ -0,0 +1,277 @@ +/** + * binsub.c / 2022-12-09 + * + * (C) 2022 Zach van Rijn + * + * MIT License + * + * This utility truncates or replaces needles in an input file; + * truncation meaning the replacement string is empty. + * + * Replacement string length must be less than or equal to that + * of the needle because the file length must remain unchanged. + * + * For efficient operation, consider deploying this on a '.tar' + * file instead of individual files within a directory. + */ + +#include +#include +#include + +/** + * Basic memory structure. + */ +struct buffer +{ + char *data; + size_t len; +}; + + +/** + * Given a needle ('find') and optional replacement ('repl'), if + * the needle is found, truncate it, inject the replacement, and + * pad the tail end of the matching string with null bytes. + * + * The file length remains the same, and we hope that nobody is + * relying on precomputed offsets into the strings.

We use it to seed our +# official build servers. This removes the dependency on using +# previous binary releases of our distribution, which had been +# manually bootstrapped way back from Gentoo and/or on a G5. +# +# +# requirements +# ------------ +# +# TL;DR: You must be able to run the mcmtools bootstrap script. +# +# Cross builds take up a lot of TIME and SPACE, and this cannot +# be improved by throwing hardware at it. This is primarily due +# to the tradeoff of not requiring root privileges at any point, +# and the decision to emulate a native environment instead of to +# force explicit cross-compilation at each step in the process. +# +# Targeting an architecture of opposite endianness will be even +# slower; this is a QEMU limitation. +# +# If you wish to bootstrap to the same target CPU architecture, +# or a compatible mode (e.g. i686 on x86_64), it will be faster. +# +# mcmtools is a hard dependency for our bootstrap process now: +# +# https://git.zv.io/toolchains/bootstrap +# +# It is a simple analog to Buildroot or Yocto. Those tools could +# be used, too, and would provide the "host rootfs" environment. +# +# Internet access is required, but (as an exercise left to the +# reader) it is possible to pre-download all required sources if +# you provide your own rootfs for the static QEMU build process. +# +# If you are in a position to use native hardware, then you are +# able to get away with only the final stages of bootstrapping. +# To do this, you'd essentially comment out the first stages or +# copy the results of the first stages elsewhere and continue. +# +# Other requirements that you should be aware of, estimated: +# +# * As many CPU cores as you can throw at it; +# +# * ~15 GB for each mcmtools rootfs ("seed" and "host"); +# +# * ~ 3 GB for toolchains; +# +# * ~ 2 GB for each intermediate rootfs; +# +# * ~ 2 GB for the "system/" package repository, when built; +# +# * Please refer to the README in 'bootstrap', linked above, +# for more information about performance. Most of this can +# be gained back if you adapt this script to use 'chroot(8)' +# instead of 'PRoot', at the expense of requiring privilege, +# with the correct registration of QEMU with 'binfmt_misc'. +# +# In brief, there is an approximate factor of 13 slowdown on +# practical workloads when using QEMU user and 'PRoot' to do +# dynamic binary translation and emulate a foreign machine. +# +# +# process +# ------- +# +# The illustration below outlines the complete bootstrap process +# and roughly corresponds to the script layout/organization.
