314195c8be3bd7db0d5817c4fb3aa85c84363ce9 Remove unnecessary cast in CKey::SignSchnorr (Pieter Wuille)
a1f76cdb22e3278a48d63dd23c1fe3308daedd8c Remove --disable-openssl-tests for libsecp256k1 configure (Pieter Wuille)
86dbc4d075decb82fbba837aaa283cf0561897ad Squashed 'src/secp256k1/' changes from be8d9c262f..0559fc6e41 (Pieter Wuille)
Pull request description:
The motivation for this bump is getting rid of a cast in `CKey::SignSchnorr`; the `aux_rand` argument isn't modified by the `secp256k1_schnorrsig_sign` function, but was marked as non-`const` anyway. This is fixed now (bitcoin-core/secp256k1#966), and the cast is removed in this PR.
There are a few other relevant changes:
* (bitcoin-core/secp256k1#956): replaces a runtime-computed table with a precomputed one; this adds arouns 1 MiB to the binary size, but is a step towards significantly simplifying the API. If 1 MiB is too much, it can be reduced by 2 or 4 (or more) for a slight verification performance reduction.
* (bitcoin-core/secp256k1#983): removes (test/bench only) OpenSSL support entirely, removing the need to pass `--disable-openssl-tests` (see #23314).
* (bitcoin-core/secp256k1#810): mild performance increase for 64-bit non-x86 platforms.
* (bitcoin-core/secp256k1#1002): Make aux_rnd32==NULL behave identical to 0x0000..00 (which impacts BIP341/BIP342 signing in Bitcoin Core, making it more strictly BIP340 compliant, though not in a manner that affects security).

ACK 314195c8be3bd7db0d5817c4fb3aa85c84363ce9 - this includes a nice simplification to the lilbsecp build system (and thus our build system), and fixes issues like #22854. Did a Guix build on x86 (above), as well as a build on arm64 (except for the arm64 host):

66a20a54a2a8446e6257b872a161089e0eed1688 build, qt: Drop support for `i686-linux-android` host (Hennadii Stepanov)
Pull request description:
There are no reasons to keep support for `i686-linux-android` host, which is actually broken in master (50c502f54abd9eb15c8ddca013f0fdfae3d132a9), and this fact has been unnoticed for months :)

We already use this in the blockfilter code, so not sure we need to maintain two
different ways of testing for the same functionality. Consolidate on testing
for __SIZEOF_INT128__, which we already use, is supported by the compilers we
care about, and is also used by libsecp256k1.

Very old shells suffered from bugs which meant that prefixing variables
with an "x" to ensure that the lefthand side of a comparison always
started with an alphanumeric character was needed. Modern shells don't
suffer from this issue (i.e Bash was fixed in 1996).
In any case, we've already got unprefixed checks used in our codebase,
i.e https://github.com/bitcoin/bitcoin/blob/master/configure.ac#L292,
and have dependencies (in depends) that also use unprefixed comparisons.
I think it's time that we can consolidate on not using the x-prefix
workaround. At best it's mostly just confusing.

68e5aafde3e87c16da95410a0474f38f589afb36 build: add `--enable-lto` configuration option (fanquake)
Pull request description:
It's been 5 years since using LTO was first suggested for use when building Bitcoin Core, and it's time to revisit it again. Compilers, and their LTO implementations, have matured, and Bitcoin Core has come a long way in terms of pruning dependencies which may have proved troublesome (i.e Boost previously had issues when using LTO). We'll have even less Boost code after moving to `std::filesystem` (#20744).
Experimenting with LTO came up on IRC last night:
> sipa: jamesob: i'm interested in knowing whether "-flto" and/or "-fdata-sections -ffunction-sections -Wl,--gc-sections" are possible/beneficial with our current compiler suite; what would be a good way to have your test infrastructure benchmark things?
So this PR just adds the bare minimum to make it easier to configure, compile and perform some bench-marking using `-flto`. This PR doesn't do anything depends wise, however if we decide this is what we want to do, I'll expand the changes here.
I had previously had a PR open (#18605) to perform link time garbage collection (`-ffunction-sections -fdata-sections` & `-Wl,--gc-sections`), however moving straight to using LTO would be preferable.
Note that our minimum required set of compilers, GCC 8.1 and Clang 7, all support the `-flto` option.
Related #18579.
Previous discussion: #10616, #14277.
Previous related PRs: #10800 (`-flto`), #16791 (ThinLTO).

cf7292597e18ffca06b0fbf8bcd545aec387e380 configure.ac: remove Bashism (Matt Whitlock)
Pull request description:
Configure scripts are supposed to adhere to the POSIX shell language. The POSIX `test` builtin does not implement an `==` operator. Bash does, but not all systems have Bash installed as `/bin/sh`. In particular, many systems use the lighter-weight Dash as the default POSIX shell. Dash emits the following error when running `configure`:
```
./configure: 39065: test: xno: unexpected operator
```
This PR removes the Bashism and restores correct operation with POSIX-compliant shells like Dash.

This was used to expose additional formatting macros in glibs / std
libs. However this is no-longer required now that we require glibc
2.18+.
See https://sourceware.org/bugzilla/show_bug.cgi?id=15366.

From what I can see the only platform this drops support for is CentOS
7. CentOS 7 reached the end of it's "full update" support at the end of
2020. It does receive maintenance updates until 2024, however I don't
think supporting glibc 2.17 until 2024 is realistic. Note that anyone
wanting to self-compile and target a glibc 2.17 runtime could build with
--disable-threadlocal.
glibc 2.18 was released in August 2013.

This takes over #21859, which has [recently switched](https://github.com/bitcoin/bitcoin/pull/21859#issuecomment-921899200) to my integration branch. A few more build issues came up (and have been fixed) since, and after discussing with sipa it was decided I would open a PR to shepherd any final changes through.
> This adds a `src/minisketch` subtree, taken from the master branch of https://github.com/sipa/minisketch, to prepare for Erlay implementation (see #21515). It gets configured for just supporting 32-bit fields (the only ones we're interested in in the context of Erlay), and some code on top is added:
> * A very basic unit test (just to make sure compilation & running works; actual correctness checking is done through minisketch's own tests).
> * A wrapper in `minisketchwrapper.{cpp,h}` that runs a benchmark to determine which field implementation to use.
Only changes since my last update to the branch in the previous PR have been rebasing on master and fixing an issue with a header in an introduced file.

AC_DEFINE'd values won't be passed down to minisketch because it does not
use bitcoin-config.h. Thus we need a way to know if we should manually add

These tests are failing when run against OpenSSL 3, and have been
removed upstream, https://github.com/bitcoin-core/secp256k1/pull/983, so
disabled them for now to avoid `make check` failures.
Note that this will also remove warning output from our build, due to
the use of deprecated OpenSSL API functions. See #23048.

`--with-system-univalue`
0f95247246344510c9a51810c14c633abb382e95 Integrate univalue into our buildsystem (Cory Fields)

Pull request description:
This PR more tightly integrates building Univalue into our build system. This follows the same approach we use for [LevelDB](https://github.com/bitcoin-core/leveldb/), ([`Makefile.leveldb.include`](https://github.com/bitcoin/bitcoin/blob/master/src/Makefile.leveldb.include)), and [CRC32C](https://github.com/bitcoin-core/crc32c) ([`Makefile.crc32c.include`](https://github.com/bitcoin/bitcoin/blob/master/src/Makefile.crc32c.include)), and will be the same approach we use for [minisketch](https://github.com/sipa/minisketch); see #23114.
This approach yields a number of benefits, including:
* Faster configuration due to one less subconfigure being run during `./configure` i.e 22s with this PR vs 26s
* Faster autoconf i.e 13s with this PR vs 17s
* Improved caching
* No more issues with compiler flags i.e https://github.com/bitcoin/bitcoin/pull/12467
* More direct control means we can build exactly the objects we want
There might be one argument against making this change, which is that builders should have the option to use "proper shared/system libraries". However, I think that falls down for a few reasons. The first being that we already don't support building with a number of system libraries (secp256k1, leveldb, crc32c); some for good reason. Univalue is really the odd one out at the moment.
Note that the only fork of Core I'm aware of, that actively patches in support for using system libs, also explicitly marks them as ["DANGEROUS"](https://github.com/bitcoinknots/bitcoin/blob/a886811721ce66eb586871706b3f5dd27518ac3e/configure.ac#L1430) and ["NOT SUPPORTED"](https://github.com/bitcoinknots/bitcoin/blob/a886811721ce66eb586871706b3f5dd27518ac3e/configure.ac#L1312). So it would seem they exist more to satisfy a distro requirement, as opposed to something that anyone should, or would actually use in practice.
PRs like #22412 highlight the "issue" with us operating with our own Univalue fork, where we actively fix bugs, and make improvements, when upstream (https://github.com/jgarzik/univalue) may not be taking those improvements, and by all accounts, is not currently actively maintained. Bitcoin Core should not be hamstrung into not being able to fix bugs in a library, and/or have to litter our source with "workarounds", i.e #22412, for bugs we've already fixed, based on the fact that an upstream project is not actively being maintained. Allowing builders to use system libs is really only exacerbating this problem, with little benefit to our project. Bitcoin Core is not quite like your average piece of distro packaged software.
There is the potential for us to give the same treatment to libsecp256k1, however it seems doing that is currently less straightforward.

Presumably these stubs indicate to packagers that external leveldb is meant to
be supported in some way. It is not. Remove the stubs to avoid sending any
mixed messages.

Pull request description:
This remove the addition of flags that are already part of other options, such as `-Wall` or `-Wextra`; see each commit message for details. All of the flags being removed here already exist as part of `-Wall` as of GCC 8, or, for Clang, all exist in `-Wmost` (included in `-Wall)`, or as part of `-Wextra` as of Clang 7. Both of which are our minimum required compilers.
Also cherry-picks one change from #21458.
To give an example of how GCCs `-Wall` has changed over the last few releases:
### 11.x to trunk (12.x)
Added:
```bash
-Wzero-length-bounds
-Wmismatched-dealloc
-Wmismatched-new-delete (only for C/C++)
```
### 10.x to 11.x
Added:
```bash
-Warray-parameter=2 (C and Objective-C only)
-Wrange-loop-construct (only for C++)
-Wsizeof-array-div
-Wvla-parameter (C and Objective-C only)
```
Removed:
```bash
-Wenum-conversion in C/ObjC;
```
### 9.x to 10.x
Added:
```bash
-Wenum-conversion in C/ObjC;
-Wformat-overflow
-Wformat-truncation
-Wzero-length-bounds
```
### 8.x to 9.x
Added:
```bash

Removed:
```bash
-Wstringop-truncation

This finishes the transition to using LIEF for the ELF symbol and security checks.
Note that there's currently a work around used for identifying RISCV binaries (just checking the interpreter). I've sent a PR upstream, https://github.com/lief-project/LIEF/pull/562, and we should be able to drop that when using LIEF 0.12.0 and onwards.

Pull request description:
No longer special case a set of warnings, to make up our own -Werror,

We keep `-Wno-error=return-type` because we know that is broken when using
mingw-w64. It should only be applied when cross-compiling for Windows.
Similar to the change in #20544, but with (hopefully) less work-arounds,
and other bundled changes. A step towards some configure "cleanups".

This addresses issues like the one in #12467, where some of our compiler flags
end up being dropped during the subconfigure of Univalue. Specifically, we're
still using the compiler-default c++ version rather than forcing c++17.
We can drop the need subconfigure completely in favor of a tighter build
integration, where the sources are listed separately from the build recipes,
so that they may be included directly by upstream projects. This is
similar to the way leveldb build integration works in Core.
Core benefits of this approach include:
- Better caching (for ex. ccache and autoconf)
- No need for a slow subconfigure
- Faster autoconf
- No more missing compile flags
- Compile only the objects needed
There are no benefits to Univalue itself that I can think of. These changes
should be a no-op there, and to downstreams as well until they take advantage
of the new sources.mk.
This also removes the option to use an external univalue to avoid similar ABI
issues with mystery binaries.

4747da3a5b639b5a336b737e7e3cbf060cf2efcf Add syscall sandboxing (seccomp-bpf) (practicalswift)
Pull request description:
Add experimental syscall sandboxing using seccomp-bpf (Linux secure computing mode).
Enable filtering of system calls using seccomp-bpf: allow only explicitly allowlisted (expected) syscalls to be called.
The syscall sandboxing implemented in this PR is an experimental feature currently available only under Linux x86-64.
To enable the experimental syscall sandbox the `-sandbox=<mode>` option must be passed to `bitcoind`:
```
-sandbox=<mode>
Use the experimental syscall sandbox in the specified mode
(-sandbox=log-and-abort or -sandbox=abort). Allow only expected
syscalls to be used by bitcoind. Note that this is an
experimental new feature that may cause bitcoind to exit or crash
unexpectedly: use with caution. In the "log-and-abort" mode the
invocation of an unexpected syscall results in a debug handler
being invoked which will log the incident and terminate the
program (without executing the unexpected syscall). In the
"abort" mode the invocation of an unexpected syscall results in
the entire process being killed immediately by the kernel without
executing the unexpected syscall.
```
The allowed syscalls are defined on a per thread basis.
I've used this feature since summer 2020 and I find it to be a helpful testing/debugging addition which makes it much easier to reason about the actual capabilities required of each type of thread in Bitcoin Core.

[About seccomp and seccomp-bpf](https://en.wikipedia.org/wiki/Seccomp):
> In computer security, seccomp (short for secure computing mode) is a facility in the Linux kernel. seccomp allows a process to make a one-way transition into a "secure" state where it cannot make any system calls except exit(), sigreturn(), and read() and write() to already-open file descriptors. Should it attempt any other system calls, the kernel will terminate the process with SIGKILL or SIGSYS. In this sense, it does not virtualize the system's resources but isolates the process from them entirely.
>
> […]
>
> seccomp-bpf is an extension to seccomp that allows filtering of system calls using a configurable policy implemented using Berkeley Packet Filter rules. It is used by OpenSSH and vsftpd as well as the Google Chrome/Chromium web browsers on Chrome OS and Linux. (In this regard seccomp-bpf achieves similar functionality, but with more flexibility and higher performance, to the older systrace—which seems to be no longer supported for Linux.)
