refactor(core/rust): use FatPtr in rust syslog binding

This commit is a small internal cleanup in the Rust code that handles device logging. It replaces manual pointer-and-length handling with a helper called FatPtr, which is designed to safely represent string slices. There is no indication t…

feat(core/rust): coerce empty slices to null FatPtrs

This commit changes how Trezor firmware passes empty data buffers from Rust code to C code. Previously, an empty Rust slice could produce a pointer that looks like a memory address but points to nothing valid. The patch forces such empty s…

feat(core/rust): separate trezor-crypto to its own Rust crate

This commit is a large but straightforward internal refactoring: the cryptographic code is moved from one Rust crate (`rtl`) into a new dedicated crate (`crypto`), and all project dependencies are updated to point to the new crate. The act…

refactor(core/embed): reorganize error handling

This commit is a code cleanup that moves how Trezor firmware handles fatal errors and shutdowns between its internal software layers. It does not add new user-facing features or change security protections. The main risk is that reorganizi…

build(xbuild): output Rust binding file even if no bindings were specified

This is a build-system maintenance change. It ensures an empty Rust bindings file is created even when no bindings are requested, and refactors how generated files are compared and written. There is no user-facing or security-relevant beha…

feat(core/sys): expose syslog as a Rust module

chore(core/rust): drop dbg_println macros from trezor_lib crate

This commit removes internal debug-only printing helpers from the Trezor firmware's Rust code. It is a cleanup change with no security relevance: the removed macros were only active when a special 'debug' build feature was enabled, and the…

feat(python): client.ensure_unlocked() works without deriving a session

This is a small optimization in the Trezor Python library. The `ensure_unlocked()` helper used to pick or create a wallet session, which forced the hardware wallet to derive the master seed just to check if the device was unlocked. The new…

This commit fixes the `trezorctl get-session` command in Trezor's Python library. It prevents crashes when an invalid session ID is supplied, ensures a required pairing step is completed when resuming secure (THP) sessions, and changes the…

Invalid input (malformed base64 session ID) previously caused an unhandled exception/crash in the CLI.THP session resumption could leave pairing in an invalid state because `pairing.finish()` was skipped when no pairing flow ran.The `passphrase=False` semantic change could affect which wallet/session is derived in CLI workflows, but the commit message frames this as matching actual intended usage.
