# The above line must be directly after the shebang line.
# Disables these warnings:
# 2030 - Modification of var is local (to subshell caused by pipeline).
# shell check 0.4.6 gets confused by the read -t 1 command and interprets
# the '1' as $1 getting modified.
# 2031 - var was modified in a subshell. That change might be lost.
# caused by shell check bug with SC2030? This causes any $1 from that
# point on to be flagged.
# 2059 - Don't use variables in the printf format string. Use printf "..%s.." "$foo".
# This is used for all of our color printing.

buildgcc: Add option to bootstrap a host gcc Bootstrapping gcc is the recommended way if your host gcc's version doesn't match the gcc version you're going to build. While a build with an outdated host gcc usually succeeds, an outdated gnat seems to be a bigger issue. v3: Some library controversy: gcc likes the libraries it ships with most but we don't want to install shared libraries. So we build them static --disable-shared) and install only the minimum (libgcc, libada, libstdc++). However, as the code of these libraries might be used to build a shared library we have to compile them with `-fPIC`. v4: o Updated getopt strings. o The workaround for clang (-fbracket-depth=1024) isn't needed for bootstrapping and also breaks the build, as clang is only used for the first stage in that case and gcc doesn't know that option. So far build tested with `make BUILDGCC_OPTIONS="-b -l c,ada"` on o Ubuntu 14.04 "Trusty Tahr" (i386) o Debian 8 "Jessie" (x86_64) (building python (-S) works too) o current Arch Linux (x86_64) o FreeBSD 10.3 (x86_64) (with gcc-aux package) and with clang host compiler, thus C only: `make BUILDGCC_OPTIONS="-b"` on o Debian 8 "Jessie" (x86_64) o FreeBSD 10.3 (x86_64) v5: Rebased after toolchain updates to GCC 5.3.0 etc. Build tested with `make BUILDGCC_OPTIONS="-b -l c,ada"` on o Debian 8 "Jessie" (x86_64) Change-Id: Icb47d3e9dbafc55737fbc3ce62a084fb9d5f359a Signed-off-by: Nico Huber <nico.huber@secunet.com> Reviewed-on: https://review.coreboot.org/13473 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi <pgeorgi@google.com>

buildgcc: Implement simple tarball hash verification This patch implements a relatively simple hash-based verification scheme for downloaded files (tarballs): After buildgcc downloads a file or notices that it has already been downloaded, it hashes the file, and compares the hash against the known hash stored in util/crossgcc/sum/$filename.cksum. Two errors can occur: 1. The hash file is missing. In this case, crossgcc asks the user to verify the authenticity of the downloaded file. It also calculates its hash and stores it in util/crossgcc/sum/$filename.cksum.calc. If the file is authentic, the user may rename the calculated hash file to $filename.cksum, so that it can be found the next time buildgcc is started. 2. The known hash and the calculated hash differ. This is the case that this patch seeks to protect against, because it may imply that the downloaded file was unexpectedly changed, either in transit (Man-in-the-Middle attack) or on the file server that it was downloaded from. If buildgcc detects such a hash mismatch, it asks the user to delete the downloaded file and retry, because it can also be caused by a benign network error. If, however, the error persists, buildgcc can't continue without risking that the user runs malicious code, and it stops. Note: The hash algorithm may be changed in the future, but for now I left it at SHA-1, to avoid bloating this patch.

buildgcc: Implement simple tarball hash verification This patch implements a relatively simple hash-based verification scheme for downloaded files (tarballs): After buildgcc downloads a file or notices that it has already been downloaded, it hashes the file, and compares the hash against the known hash stored in util/crossgcc/sum/$filename.cksum. Two errors can occur: 1. The hash file is missing. In this case, crossgcc asks the user to verify the authenticity of the downloaded file. It also calculates its hash and stores it in util/crossgcc/sum/$filename.cksum.calc. If the file is authentic, the user may rename the calculated hash file to $filename.cksum, so that it can be found the next time buildgcc is started. 2. The known hash and the calculated hash differ. This is the case that this patch seeks to protect against, because it may imply that the downloaded file was unexpectedly changed, either in transit (Man-in-the-Middle attack) or on the file server that it was downloaded from. If buildgcc detects such a hash mismatch, it asks the user to delete the downloaded file and retry, because it can also be caused by a benign network error. If, however, the error persists, buildgcc can't continue without risking that the user runs malicious code, and it stops. Note: The hash algorithm may be changed in the future, but for now I left it at SHA-1, to avoid bloating this patch.
