* PhoneAPI: gate local admin on the connection, not the wire from The lockdown admin check in handleToRadioPacket only ran when p.from == 0. from is a client-supplied wire field, and MeshService::handleToRadio rewrites it to 0 before AdminModule sees the packet. A client could therefore set from != 0 to skip the !getAdminAuthorized() drop, then have the packet normalized back to a local-admin identity and executed - unauthorized admin from an unauthorized connection. Every packet in handleToRadioPacket already comes from the local connection, so locality is a property of the connection, not of from. Move the decision into classifyLocalAdminPacket(), which ignores from and keys only on the admin variant and the connection's authorization: lockdown_auth is delivered inline, any other admin from an unauthorized connection is dropped, authorized admin passes through. The classifier is compiled unconditionally and unit-tested; the guarded caller (built only in the nRF52 lockdown config) calls it. Test: an unauthorized connection's ADMIN_APP packet with from != 0 is classified DropUnauthorized. * PhoneAPI: wipe the encoded lockdown passphrase, shorten comments --------- Co-authored-by: Ben Meadors <benmmeadors@gmail.com>
Meshtastic Firmware
Overview
This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.
Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
