Dynapatchv15zip -

Prepared as a stand‑alone technical overview for anyone looking to understand, evaluate, or integrate Dynapatch v15 delivered as a ZIP distribution.

The developers have stated that v1.5 will likely be the final major update for the current framework before the transition to the "DynaNext" engine. This patch is considered the "Stable Golden Master" for legacy users. dynapatchv15zip

| Step | Bare‑Metal (Cortex‑M4) | Linux (x86‑64) | RISC‑V Linux | |---|---|---|---| | 1. Flash Loader | Write dynapatch_loader.bin into a reserved boot‑sector region (e.g., 0x0800 8000). | Place dynapatch_loader in /usr/local/bin. | Same as Linux x86‑64. | | 2. Runtime Library | Link libdynapatch.a statically into your main firmware image. | Ensure libdynapatch.so is in /usr/lib and ldconfig refreshed. | Same as Linux x86‑64. | | 3. Register Extensions | Compile any C plug‑ins with the provided dynapatch_sdk.h and embed them in the firmware image. | Drop compiled .so files into /opt/dynapatch/extensions/. | Same as Linux x86‑64. | | 4. Apply First Patch | Call dynapatch_apply("patch_001.cpbf") from your main loop. | Run sudo dynapatch_loader --apply patches/patch_001.cpbf. | Same as Linux x86‑64. | | 5. Verify | Inspect the PATCH_STATUS register (custom). | dynapatch_loader --status prints JSON with commit state. | Same as Linux x86‑64. | The developers have stated that v1

| Threat | Mitigation Built‑In | |---|---| | Replay Attack | Each patch carries a monotonic sequence_number and a timestamp. The runtime refuses patches with older numbers. | | Man‑in‑the‑Middle (MITM) | The detached CMS signature is verified against a root CA that is not stored on the host device; it must be provisioned securely during manufacturing. | | Code‑Injection via Malformed CPBF | CPBF parser validates instruction boundaries and enforces a whitelist of allowed opcodes per platform. | | Denial‑of‑Service (excessive patch size) | Transaction manager imposes a configurable max_patch_size (default 256 KB). | | Side‑Channel Leakage | JIT translation runs in a constant‑time path when the DP_SECURE_MODE flag is set, eliminating timing variance based on patch contents. |

The original distribution sites are long gone, but dynapatchv15zip is preserved on archival platforms like Internet Archive and certain GitHub repositories dedicated to legacy tooling. Expect to find it under hashes like sha256:9a4b6c... (always verify checksums when downloading retro binaries).
