This adds a sanity check that the version is being set as expected. Clangs Darwin driver should infer the SDK version used during compilation, and forward that through to the linker. Add a check that this has been done, and the expected SDK version is set. Should help prevent issues like #21771 in future. Windows: We use linker flags ([-Wl,--major/minor-subsystem-version](https://github.com/bitcoin/bitcoin/blob/master/configure.ac#L683)) to set the minimum required version of Windows needed to run our binaries. This adds a sanity check that the version is being set as expected.

and hierarchy e2c40a4ed5272d72fea997bd936fba28bb753226 guix-attest: Error out if SHA256SUMS is unexpected (Carl Dong) 4cc35daed557f38b080360a89036b2e97a6f78c2 Rewrite guix-{attest,verify} for new hier (Carl Dong) 28a9c9b83924f585b397f0f3b8e9e73780ac0ad6 Make SHA256SUMS fragment right after build (Carl Dong) Pull request description: Based on: #22075 Code reviewers: I recommend reading the new `guix-{attest,verify}` files instead of trying to read the diff The following changes resolve many usability improvements which were pointed out to me: 1. Some maintainers like to extract their "uncodesigned tarball" inside the `output/` directory, resulting in the older `guix-attest` mistakenly attesting to the extracted contents 2. Maintainers whose GPG keys reside on an external smartcard often need to physically interact with the smartcard as a way to approve the signing operation, having one signature per platform means a lot of fidgeting 3. Maintainers wishing to sign on a separate machine now has the option of transferring only a subtree of `output/`, namely `output/*/SHA256SUMS.part`, in order to perform a signature (you may need to specify an `$OUTDIR_BASE` env var) 4. An `all.SHA256SUMS` file should be usable as the base `SHA256SUMS` in bitcoin core torrents and on the release server. For those who sign on an separate machine than the one you do builds on, the following steps will work: 1. `env GUIX_SIGS_REPO=/home/achow101/guix.sigs SIGNER=achow101 NO_SIGN=1 ./contrib/guix/guix-attest` 2. Copy `/home/achow101/guix.sigs/<tag>/achow101` (which does not yet have signatures) to signing machine 3. Sign the `SHA256SUMS` files: ```bash for i in "<path-to-achow101>/*.SHA256SUMS"; do gpg --detach-sign --local-user "<your-key-here>" --armor --output "$i"{.asc,} done ``` 5. Upload `<path-to-achow101>` (now with signatures) to `guix.sigs` ----- After this change, output directories will now include a `SHA256SUMS.part` fragment, created immediately after a successful build: ``` output └── x86_64-w64-mingw32 ├── bitcoin-4e069f7589da-win64-debug.zip ├── bitcoin-4e069f7589da-win64-setup-unsigned.exe ├── bitcoin-4e069f7589da-win64.zip ├── bitcoin-4e069f7589da-win-unsigned.tar.gz └── SHA256SUMS.part ``` These `SHA256SUMS.part` fragments look something like: ``` 3ebd7262b1a0a5bb757fef1f70e7e14033c70f98c059bc4dbfee5d1992b25825 dist-archive/bitcoin-4e069f7589da.tar.gz def2e7d3de5ab3e3f955344e75151df4f33713f9101f5295bd13c9375bdf633b x86_64-w64-mingw32/bitcoin-4e069f7589da-win64-debug.zip 643049fe3ee4a4e83a1739607e67b11b7c9b1a66208a6f35a9ff634ba795500e x86_64-w64-mingw32/bitcoin-4e069f7589da-win64-setup-unsigned.exe a247a1ccec0ccc2e138c648284bd01f6a761f2d8d6d07d91b5b4a6670ec3f288 x86_64-w64-mingw32/bitcoin-4e069f7589da-win-unsigned.tar.gz fab76a836dcc592e39c04fd2396696633fb6eb56e39ecbf6c909bd173ed4280c x86_64-w64-mingw32/bitcoin-4e069f7589da-win64.zip ``` Meaning that they are valid `SHA256SUMS` files when `sha256sum --check`'d at the `guix-build-*/output` directory level When `guix-attest` is invoked, these `SHA256SUMS.part` files are combined and sorted (by `-k2`, `LC_ALL=C`) to create: 1. `noncodesigned.SHA256SUMS` for a manifest of all non-codesigned outputs, and 3. `all.SHA256SUMS` for a manifest of all outputs including non-codesigned outputs Then both files are signed, resulting in the following `guix.sigs` hierarchy: ``` 4e069f7589da/ └── dongcarl ├── all.SHA256SUMS ├── all.SHA256SUMS.asc ├── noncodesigned.SHA256SUMS └── noncodesigned.SHA256SUMS.asc ``` ACKs for top commit: achow101: ACK e2c40a4ed5272d72fea997bd936fba28bb753226 hebasto: ACK e2c40a4ed5272d72fea997bd936fba28bb753226, tested on Linux Mint 20.1 (x86_64) with and w/o `NO_SIGN=1`.

It replaces our current approach of manually parsing the output of `objdump` & `otool`. If the consensus is that using LIEF is ok, then I also plan on replacing [pixie.py](https://github.com/bitcoin/bitcoin/blob/master/contrib/devtools/pixie.py), and using LIEF for all checks. LIEF for Linux is also currently blocked (on the next release, unless we want to build master) on one change for RISC-V that I [sent upstream](https://github.com/lief-project/LIEF/pull/562). LIEF is seemingly well maintained, and is the basis for a number of other tools. It also has some very nice documentation; i.e the [Python API for ELF](https://lief.quarkslab.com/doc/latest/api/python/elf.html). It also has many builtins we can take advantage of. i.e [`is_pie`](https://lief.quarkslab.com/doc/latest/api/python/macho.html#lief.MachO.Binary.is_pie), [`has_nx`](https://lief.quarkslab.com/doc/latest/api/python/macho.html#lief.MachO.Binary.has_nx) etc. This means we can [consolidate some of our checks](https://github.com/bitcoin/bitcoin/commit/9c5eeb54848f428109ec24dff55f189a5358e9bc). If/when end up using LIEF for lightning then we can consolidate further, and cleanup these scripts. i.e to not parse the binary inside the checks, but once at the start of the script.

2021-05-03guix: Consistently use gcc-8 for $HOSTCarl Dong
2021-05-01guix: use Clang 10 for the macOS cross compilefanquake
2021-04-05guix: Build dmg as a static binaryCarl Dong
This relatively easy change eliminates all runtime dependencies (except for the kernel) for dmg, which is the only native build tool that gets put in our output tarballs. This allows much more flexibility when constructing the codesigning environment, and is much more robust.

2021-02-24guix: Bump glibc and linux-headersCarl Dong
Bump glibc and linux-headers to match those of our Gitian counterparts. We also require a glibc >= 2.28 for the test-symbol-check scripts to work properly. The default BASE-GCC-FOR-LIBC also has to be bumped since glibc 2.31 requires a gcc >= 6.2
2021-02-19guix: Add support for powerpc64{,le}Carl Dong
The new time-machine commit contains a few small changes that make the powerpc cross-toolchain work.
2021-02-18guix: Jump forwards in time-machine and adaptCarl Dong
The new time-machine commit is Guix v1.2.0 with a yet-unupstreamed patch for NSIS. A few important changes: 1. Guix switched back from using CPATH to C{,PLUS}_INCLUDE_PATH as the way to indicate #include search paths. 2. GCC's library is now split into a separate output, whereas before it was included in the default output. This means that our gcc toolchain packages need to propagate that output. 3. A few package versions were bumped

2021-01-17guix: Make nsis reproducible by respecting SOURCE-DATE-EPOCHCarl Dong
When building nsis, if VERSION is not specified, it defaults to cvs_version which is non-deterministic as it includes the current date. This patches nsis to default to SOURCE_DATE_EPOCH if it exists so that nsis is reproducible. Upstream change: https://github.com/kichik/nsis/pull/13
2020-04-28guix: Make source tarball using git-archiveCarl Dong
2020-04-07guix: Use gcc-9 for mingw-w64 instead of 8Carl Dong
The libtool unsorted 'find' determinism issue seemed to have been solved in gcc-9's git: d41cd173e23ebea7c758644d6ad6e0fde1c2e3a6 or SVN: r262451 Furthermore, it seems that Ubuntu Focal 20.04 LTS is going to ship with gcc 9 and mingw-w64 7, which will match what we have now. ----- A note on this: Careful observers will see that previously I stated that all released versions of gcc were bootstrapped with a libtool 2.2.7a, meaning that they all had the unsorted 'find' determinism issue first resolved in libtool 2.2.7b. However, I was mistaken, gcc's ltmain.sh CLAIMS it was generated by libtool 2.2.7a, but it was in fact edited manually. It seems that gcc maintains their own versions of ltmain.sh and libtool.m4, and only sometimes backports patches from upstream. Quite confusing.
2020-04-02guix: Check mingw symbols, improve SSP fix docsCarl Dong
2020-04-02guix: Reinstate make-ssp-fixed-gccCarl Dong
Unfortunately, gcc is still not smart enough to detect whether or not mingw-w64 provides ssp, so let's put it back just for mingw-w64.
2020-04-02guix: Use gcc-8 for mingw-w64 instead of 7Carl Dong
We're using mingw-w64 6.0.0, which is paired with gcc-8 in most distros.
2020-04-02guix: Build support for WindowsCarl Dong
2020-03-11guix: Remove now-unnecessary gcc make flagCarl Dong
Previously, Guix would produce a gcc which did not know to use the SSP function from glibc, and required a gcc make flag for it to do so, in my attempt to fix it upstream I realized that this is no longer the case. This can be verified by performing a Guix build and doing readelf -s ... | grep __stack_chk to check that symbols are coming from glibc, and doing readelf -d ... | grep NEEDED | grep ssp to see that libssp.so is not being depended on

2019-07-12contrib: guix: Various improvements.Carl Dong
- Clearer and more accurate prose - Pin `guix pull' to commit rather than branch - Just use `use-module' instead of `define-module' - Use `bash-minimal' instead of `bash' - Remove unneeded `tcsh' from manifest - Explicitly use `python-3.7' - Add comments about how {native,cross}-toolchains are produced and why
