AI analysis · Informational 15/100

This commit is a routine cleanup of the GitHub Actions workflow that builds Trezor emulator releases. It removes unused matrix dimensions (like ASan variants), drops environment variables that were no longer needed, changes a default so the bootloader build step is skipped unless explicitly requested, and passes the device model into the build command. There is no change to the firmware code that runs on user devices, no fix for a vulnerability, and no security-relevant behavior change.

57/100 · ThinMessage clarity
✓ Descriptive subject✓ Names a concrete action or component✓ Uses a recognizable type or scope! No meaningful explanatory body

This commit removes the full build directory path from the firmware binary by switching from __FILE__ to __FILE_NAME__ in two error-handling locations. The change reduces information leakage but does not fix a memory corruption or logic bug. It is a hardening/information-disclosure reduction patch, not a fix for an actively exploitable vulnerability.

This commit only adds comments explaining why the code does not overwrite SD card salt files with random data before deleting them. It changes no behavior, logic, or security controls. The documentation argues that overwriting is unnecessary because the encrypted data key stored inside the device is already wiped when the salt is changed, so an old recovered salt cannot decrypt anything.

This is a routine automated dependency update by Dependabot that bumps the urllib3 library from version 2.6.3 to 2.7.0 inside a small internal testing tool (automatic_battery_tester). The change is a single line in a requirements file. There is no indication in the commit that this fixes a security issue, and the tool is not part of the Trezor firmware that runs on user devices.

This is a routine build-environment cleanup. The developers removed an old copy of Nix packages (oldNixpkgs) used only for older SDL2 graphics libraries, because the project now uses SDL3. They added a compatibility package so old test emulators still work, and updated documentation and a download script to use a fuller Nix shell environment. There is no indication this changes any wallet, firmware, or cryptographic code, and no security relevance is claimed.

This commit adds a new optional sanity-check layer to the Python code that parses Trezor firmware files. It verifies that re-encoding a parsed firmware image produces the exact same bytes, and that any 'reserved' fields are all zeroes. The change is defensive: it can help detect malformed or tampered firmware images during analysis, but the strict mode is off by default, so existing behavior is preserved unless a caller explicitly opts in.

This commit only adjusts how long automated test jobs are allowed to run in GitHub Actions for one Trezor hardware model (T3W1). It extends a pytest session timeout from 40 minutes to 50 minutes and the overall CI job timeout from 50 minutes to 60 minutes, but only for the T3W1 model. There is no change to firmware code, cryptography, user data handling, or device behavior. It is purely a CI configuration tweak to prevent false timeout failures when running tests with two workers.

fix(solana): break import cycle in types.py

types.py: from .transaction.parse import parse_pubkey
transaction/__init__.py: from ..types import AddressType

The cycle is broken by making the first import lazy.

This is a routine code cleanup that fixes a Python import cycle (two files importing each other) by moving one import to happen only when a specific function runs. There is no security-relevant change visible in the diff.

refactor(core): move is_printable_ascii to common

This is a preparatory commit. The utility will be used in solana
off-chain message parsing, so we move it from cardano/helpers/utils
to common/signverify.

This commit simply moves a small helper function that checks whether a string contains only normal printable characters from one file to another shared location. No behavior changes, no bug fixes, and no security implications are visible in the code change itself.

This commit only adds new automated tests for a Solana feature that signs and verifies off-chain messages. It does not change the actual wallet firmware code that users rely on, so it cannot by itself introduce a security vulnerability or fix one. The tests exercise parsing, signing, and verification logic and include checks for invalid inputs.

feat(solana): add off-chain message signing

Implements the Solana off-chain message signing standard v0
as specified here:

https://docs.anza.xyz/proposals/off-chain-message-signing

The implementation deviates from the spec in the supported
message formats --- the spec says that HW wallets should clear-
sign format 0 (ascii), blind-sign format 1 (short utf-8), and
not support format 2 (long utf-8) messages. We try to clear-sign
messages irrespective of the format. The rationale is that we
__can__ display even longer messages incl. some non-ascii chars
and thus the limitation is arbitrary. Moreover, this restriction
is removed in the newer v1 spec, see:

https://github.com/solana-foundation/SRFCs/discussions/3

Closes: https://github.com/trezor/trezor-firmware/issues/6759

This commit adds a new Trezor feature: signing and verifying Solana off-chain messages. It is a feature implementation, not a fix for a known vulnerability. The code introduces new message types, parsing logic, user confirmation screens, and client helpers. There is no direct evidence in the commit of a security bug, but any new signing path increases the attack surface and must be reviewed carefully for parsing mistakes or user-interface spoofing.
