build(tri-pi): add aarch64 + armhf cross toolchains, QEMU test harness, ARM64 libtor build
Five files for tri-pi cross-compilation and ARM64 Tor support: - cmake/aarch64-toolchain.cmake: CMake toolchain file for aarch64-linux-gnu - cmake/armhf-toolchain.cmake: same, for arm-linux-gnueabihf - scripts/tri-pi-test.sh: QEMU-based test harness (user-mode + full-system) for Pi 3B/3A+/4B/5. Runs the cross-compiled trianglesd under qemu-aarch64-static so ARM binary correctness can be validated without physical Pi hardware. - src/tor/build-libtor-aarch64.sh: cross-compile libtor.a for aarch64 using the vendored configure flow from src/tor/configure.vendored. These accompany the in-progress tri-pi bootstrap work (Hetzner Pi, raspbian packaging). Also staged (separately from the build scripts above): - src/test/fuzz/transaction_deserialize_fuzz.cpp: libFuzzer harness for CTransaction deserialization. Reads raw attacker-controlled bytes into a CDataStream and calls Unserialize on a CTransaction, then exercises hash determinism, round-trip serialize/parse, and CheckTransaction bounds. Mirrors the Bitcoin Core deserialize-fuzz pattern. Not yet wired into src/CMakeLists.txt — the BUILD_FUZZ=ON gate currently only builds fuzz_script; a follow-up patch should add the analogous stanza for this target.

# tri-pi-test.sh — Run Triangles on emulated Raspberry Pi variants via QEMU
|
||||
#
|
||||
# Usage:
|
||||
# ./tri-pi-test.sh [pi-model] [tri-args...]
|
||||
#
|
||||
# Pi models supported (aarch64):
|
||||
# pi3 Pi 3B/3A+ (Cortex-A53, 64-bit) — user-mode QEMU
|
||||
# pi4 Pi 4B (Cortex-A72, 64-bit) — user-mode QEMU
|
||||
# pi5 Pi 5 (Cortex-A76, 64-bit) — user-mode QEMU
|
||||
# pi3-full Pi 3B — full system emulation (qemu-system-aarch64 -M raspi3b)
|
||||
#
|
||||
# Examples:
|
||||
# ./tri-pi-test.sh pi3 --version
|
||||
# ./tri-pi-test.sh pi4 -regtest -notor -recovery-mode=1 -printtoconsole
|
||||
# ./tri-pi-test.sh pi3-full # boots a full Pi OS (needs rootfs image)
|
||||
#
|
||||
# The aarch64 tri binaries are cross-compiled on DNS2 and run under
|
||||
# qemu-aarch64-static. This tests the ARM binary's correctness — ABI
|
||||
# compatibility, library resolution, crypto operations, database access,
|
||||
# and Tor integration — without needing physical Pi hardware.
|
||||
#
|
||||
# For full-system emulation (testing kernel/hardware/driver interaction),
|
||||
# use pi3-full mode with a Raspberry Pi OS rootfs.

||||
