Now that our release binaries are build in a glibc 2.24 and 2.27
environment, we can't use a symbol from glibc 2.28 to test our checks.
Replace renameat2() with nextup(), which was introduced in 2.24.
Note that this also means re-disabling the test for RISC-V, however
RISC-V is built in a glibc 2.27 environment, and our minimum required
glibc for that binary is 2.27.
We use these flags in our test-security-check make target, but they are
only available because debian patches them in.
We can patch them in for our Guix builds so that we can check the sanity
of our security/symbol checking suite before running them.
This is important to make sure that we're not testing tools different
from the one we're building with.
Introduce determine_wellknown_cmd, which encapsulates how we
should handle well-known tools specification (IFS splitting, env
override, etc.).
Now that our Guix builds are performed on glibc 2.24 and 2.27 (RISCV),
we no-longer need to pass the --enable-glibc-back-compat option.
Replace it with --disable-threadlocal, to prevent the usage of symbols
from glibc 2.18.
None of the binaries produced required symbols later than 2.17, and 2.27
(RISCV).
Our 'bitcoin-linux-g++' definition better integrates with our depends
system than the stock linux-g++-64 definition.
This fixes a bug whereby Guix builds on x86_64 for x86_64 did not
produce a QMinimalIntegrationPlugin and led to bitcoin-qt not being
built.
Support for riscv64 in glibc landed in 2.27 so it's unavoidable that we
use 2.27.
Running a Bitcoin build with toolchains based on 2.24 for platforms
other than riscv64 seem to produce binaries which do not have 2.17
symbols. So use 2.24 since it's more recent and maintained by Debian
Stretch.

2ce7b47958 test: introduce `tx_from_hex` helper for tx deserialization (Sebastian Falbesoner)
Pull request description:
There are still many functional tests that perform conversions from a hex-string to a message object (deserialization) manually. This PR identifies all those instances and replaces them with a newly introduced helper `tx_from_hex`.
Instances were found via
* `git grep "deserialize.*BytesIO"`
and some of them manually, when it were not one-liners.
Further, the helper `ToHex` was removed and simply replaced by `.serialize().hex()`, since now both variants are in use (sometimes even within the same test) and using the helper doesn't really have an advantage in readability.

Pull request description:
I misunderstood the ELF specification for version symbols (verneed): The `vn_aux` pointer is relative to the main verneed record, not the start of the section.
This caused many symbols to not be versioned properly in the return value of `elf.dyn_symbols`. This was discovered in #21454.
Fix it by correcting the offset computation.
- xkb versions symbols (using the prefix `V`), as this library is used by bitcoin-qt, add it to the valid versions in `symbol-check.py`

e2c40a4ed5 guix-attest: Error out if SHA256SUMS is unexpected (Carl Dong)
4cc35daed5 Rewrite guix-{attest,verify} for new hier (Carl Dong)
28a9c9b839 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:
```

```
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:
```

Pull request description:
This patch removes support in Bitcoin Core for Tor v2 onions, which are already removed from the release of Tor 0.4.6.
- no longer serialize/deserialize and relay Tor v2 addresses
- ignore incoming Tor v2 addresses
- remove Tor v2 addresses from the addrman and peers.dat on node launch
- update generate-seeds.py to ignore Tor v2 addresses
- remove Tor v2 hard-coded seeds
Tested with tor-0.4.6.1-alpha (no v2 support) and 0.4.5.7 (v2 support). With the latest Tor (no v2 support), this removes all the warnings like those reported with current master in https://github.com/bitcoin/bitcoin/issues/21351
```
<bitcoind debug log>
Socks5() connect to […].onion:8333 failed: general failure
<tor log>
Invalid hostname [scrubbed]; rejecting
```
and the addrman no longer has Tor v2 addresses on launching bitcoind.
```rake
$ ./src/bitcoin-cli -addrinfo
{
"addresses_known": {
"ipv4": 44483,
"ipv6": 8467,
"torv2": 0,
"torv3": 2296,
"i2p": 6,
"total": 55252
}
}
```
After recompiling back to current master and restarting with either of the two Tor versions (0.4.5.7 or 0.4.6.1), -addrinfo initially returns 0 Tor v2 addresses and then begins finding them again.
Ran nodes on this patch over the past week on mainnet/testnet/signet/regtest after building with DEBUG_ADDRMAN.
Verified that this patch bootstraps an onlynet=onion node from the Tor v3 hardcoded fixed seeds on mainnet and testnet and connects to blocks and v3 onion peers: `rm ~/.bitcoin/testnet3/peers.dat ; ./src/bitcoind -testnet -dnsseed=0 -onlynet=onion`
Tested using `addnode`, `getaddednodeinfo`,`addpeeraddress`, `disconnectnode` and `-addrinfo` that a currently valid, connectable Tor v2 peer can no longer be added:
Thanks to Vasil Dimov, Carl Dong, and Wladimir J. van der Laan for their work on BIP155 and Tor v3 that got us here.

a58868d201 build: Makes rcc output always deterministic (Hennadii Stepanov)
Pull request description:
The Qt Resource Compiler ([rcc](https://doc.qt.io/qt-5/rcc.html)) has a command-line option `--format-version` which has the [default value](https://code.qt.io/cgit/qt/qtbase.git/tree/src/tools/rcc/main.cpp?h=5.12.10#n172) 2.
The only difference from `--format-version 1` is adding a [last modified timestamp](https://code.qt.io/cgit/qt/qtbase.git/tree/src/tools/rcc/rcc.cpp?h=5.12.10#n207) to the output file ([credits](https://github.com/bitcoin/bitcoin/pull/21654#issuecomment-819198228) to **fanquake**). That, in turn, forces us to use `QT_RCC_SOURCE_DATE_OVERRIDE=1` to get deterministic builds (#13732).
This change makes rcc output always deterministic by using `--format-version 1` option that makes usage of the
`QT_RCC_SOURCE_DATE_OVERRIDE` needless.

6fe0516858 contrib: add torv3 seed nodes for testnet, drop v2 ones (Jon Atack)
Pull request description:
Replace the ancient (2015) Tor V2 hardcoded seeds with new Tor V3 ones. This needs to be done before 0.22 to make sure onion-only testnet nodes can still connect to the network. Continues #21560.
Ways to test:
- Re-generate ` src/chainparamsseeds.h` with `cd contrib/seeds && python3 generate-seeds.py . > ../../src/chainparamsseeds.h`, check if git tree stays the same.
- Create a new testnet node with `bitcoind -testnet -onlynet=onion -proxy=127.0.0.1:9050` (or delete `~/.bitcoin/testnet3/peers.dat`), check if it is able to connect to the network and get blocks.
- Check if the addresses are connectable for ex.:
```python3
#!/usr/bin/env python3
import subprocess
with open('contrib/seeds/nodes_test.txt') as f:
for line in (line for line in (line.rstrip().split('#', 1)[0] for line in f) if line):
subprocess.call(["nc", "-v", "-x", "127.0.0.1:9050", "-z"] + line.split(':'))
```

c090a3e923 Makefile.am: use APP_DIST_DIR instead of hard-coding dist (Carl Dong)
Pull request description:
This is the last PR before we reach feature-parity with the Gitian process!
Note: I tried using the `Makefile` inside the distsrc to make the dmg instead of manually listing out the commands, but `make` seems to want to re-make a lot of other files which broke the dmg.
The workflow looks something like this:
1. `env [ FOO=bar... ] ./contrib/guix/guix-build` (add additional env vars as necessary)
2. Codesigners only:
1. Copy `guix-build-<short-id>/output/x86_64-apple-darwin18/bitcoin-<short-id>-osx-unsigned.tar.gz` and `guix-build-<short-id>/output/x86_64-w64-mingw32/bitcoin-<short-id>-win-unsigned.tar.gz` to signing computer
2. Codesign with `./detached-sig-create.sh` inside the tarball
3. Upload contents of `signature-{osx,win}.tar.gz` to https://github.com/bitcoin-core/bitcoin-detached-sigs (as a new tag)
3. Checkout new tag for `bitcoin-core/bitcoin-detached-sigs` with the detached signatures
4. `env [ FOO=bar... ] DETACHED_SIGS_REPO=<path/to/bitcoin-detached-sigs> ./contrib/guix/guix-codesign` (modify env vars as necessary)
5. Make sure `guix.sigs` is cloned and updated
6. `env GUIX_SIGS_REPO=<path/to/guix.sigs> SIGNER=0x96AB007F1A7ED999=dongcarl ./contrib/guix/guix-attest` (modify env vars as necessary)
7. Commit your new signatures and SHA256SUMS in `guix.sigs`
8. Optionally, after there are multiple signatures in `guix.sigs`: `env GUIX_SIGS_REPO=<path/to/guix.sigs> ./contrib/guix/guix-verify`

42b589d18f scripts: test for MACHO control flow instrumentation (fanquake)
469a5bc4fa build: build Boost with -fcf-protection when targeting Darwin (fanquake)
Pull request description:
Addresses the macOS portion of #21888.
Build Boost with `-fcf-protection` when targeting Darwin. This should be ok, because our cross-compiler (Clang 10) supports the option, and I'd expect all versions of Apple Clang being used to compile Core would also support it. Building Boost with this option is required so that the `main` provided to `test_bitcoin` has instrumentation.
Note that the presence of instrumentation does not mean it will be used, as that is determined at runtime by the CPU.
From the Intel control flow enforcement documentation:
> The ENDBR32 and ENDBR64 instructions will have the same effect as the NOP instruction on Intel 64 processors that do not support CET. On processors supporting CET, these instructions do not change register or flag state. This allows CET instrumented programs to execute on processors that do not support CET. Even when CET is supported and enabled, these NOP–like instructions do not affect the execution state of the program, do not cause any additional register pressure, and are minimally intrusive from power and performance perspectives.
Follow up from #21135.
