Read identities up to three times before allowing replacement, publish only complete reads, and require new startup keys to be saved with bounded retries.
Use authoritative replay-file metadata throughout persistence and clock recovery. Validate setperm input before narrowing or mutating roles, and add production-path regression coverage.
Recover usable ESP32 preferences and channels before permitting replacement; keep identity and ACL persistence transactional and complete.
Preserve MQTT commit boundaries, restore OTA identity and policy after deferred allocation, retain radio gain retries, and reject invalid flood limits. Add production-path fault regressions and CI coverage.
Integrate ExpressLRS TX module support and its stacked ESP32 heap changes.
Use the approved Linkflow calibration (17-30 dBm), preserve the PA drive
and output path after radio recovery, and keep LoRa OTA enabled.
Preserve stored ACLs and filters on allocation failure, release owned
client/filter buffers, service heap OTA contexts on Companions, release
self-serving workspaces after TempRadio, and reset staged-resume state
when a context is released. Keep manual staging and active operations
alive. Account for all moved allocations in the runtime RAM gate.
Validation: 1,393 native cases; radio-power, heap-context, ACL persistence,
shared-queue transfer, display/inbox, radio receive, and memory regressions.
Firmware builds passed for Linkflow, Heltec V2 Companion, T-Beam MQTT
repeater, Heltec V4 R8 MQTT repeater, RAK4631 repeater, and Indicator Full.
Physical verification awaits access to the currently offline lab Pi.
Classic ESP32 links into a dram0_0_seg of only 124,580 bytes: memory.ld
carves the BT controller's 0xdb5c (56,156) reservation off the 0x2c200
window before the application gets any. Three large objects dominated what
was left, and Tbeam_SX1262_repeater_observer_mqtt overran the build's 8 KiB
static reserve by 4,744 bytes.
Heap-allocate them instead, each with a defined behaviour when the
allocation fails:
- OtaContext: generalize the Companion's borrowed-storage path behind
OTA_DYNAMIC_CONTEXT and add OTA_HEAP_CONTEXT, which allocates the context
on first use and frees it once no transfer, apply or folder link needs it.
A repeater is idle nearly all the time, so the workspace is usually absent.
Exhaustion is reported to the caller and the operation declines.
- ClientACL: the client table becomes a pointer with a live capacity;
capacity 0 refuses new clients rather than writing through a null table.
- MyMesh flood packet filters: likewise, with flood_packet_filter_slots as
the live bound for every rule loop. At capacity 0 the node forwards
unfiltered, and both save paths refuse to write so a stored ruleset is
never replaced by an empty file.
Also override the Arduino SDK's weak btInUse() in simple_repeater so
initArduino() releases the BT controller memory to the heap. That grows the
runtime heap these tables now come from; it cannot recover the same
reservation from the linker's static window.
Static DRAM, classic ESP32:
Heltec_v2_repeater 108,332 -> 70,732
Tbeam_SX1262_repeater_observer_mqtt 121,132 -> 83,532 (was failing)
Add durable TempRadio, ACL, clock, bridge, GPS/I2C, USB logging, and Indicator recovery safeguards together with expanded automation, build/profile contracts, release metadata, and the hardware validation ledger.
Introduces a fourth ACL role (value 4) that can manage the region map
without full admin privileges. The role is intended for trusted users
who curate regions on a repeater but should not have access to general
admin commands.
ClientACL:
- Widen PERM_ACL_ROLE_MASK from 2 to 3 bits so the new value fits.
- Add PERM_ACL_REGION_MGR and ClientInfo::isRegionMgr().
- Exempt region_mgr entries from least-recently-active eviction in
putClient(), same as admins.
simple_repeater:
- Phones may still gate UI on the legacy is_admin byte (reply_data[6]),
so report region_mgr as admin there. Without this, the phone CLI
falls back to guest view.
- Allow region_mgr to send TXT_MSG CLI commands. handleCommand()
gates non-whitelisted commands with "Err - not permitted". The
whitelist covers region.* (read+write) plus a small set of
read-only queries (get, ver, board, neighbors, clock, sensor
get/list).
- Pass the ClientInfo* through to handleCommand and drop the
redundant sender_timestamp parameter (derived from
sender->last_timestamp; NULL means Serial CLI).
- Use ~PERM_ACL_ROLE_MASK instead of ~0x03 when clearing role bits
on login, so the wider mask is honored.
