sc_derive_node_id() hashed the private key, while invite links
(joindialog.cpp) hashed the public key — giving two different
node_ids for the same keypair.
Removed sc_derive_node_id(), kept only sc_derive_node_id_from_pubkey().
All callers updated to use pubkey-based derivation.
Added #ifdef __cplusplus / extern "C" { ... } / #endif to ~65 headers
in src/ and lib/, enabling the C library to be linked into C++ code (chatgui).
Fixed packet_dump.h (added missing header guard) and etcp_bbr.h
(#pragma once guard).
- Add ed25519_public_key[32] to NODEINFO struct for pubkey distribution
- Add ed25519_public_key[32] to ROUTE_BGP (derived from X25519 privkey at init)
- Add ROUTER_FLAG_SIGNED (0x08) to SVC_ROUTE_HDR flags byte
- router_send_one_flags: when is_signed, sign [hdr][payload] and append 64-byte sig
- etcp_router_recv_cb: verify Ed25519 signature when ROUTER_FLAG_SIGNED set
- New API: etcp_router_conn_send_signed()
- Drop signed packets if sender node not in routing table or no Ed25519 key
- 5 unit tests in test_etcp_router_unit.c covering OK/tampered/unknown/no-key/short
Fixed critical bug where my_public_key was not being generated when auto-adding
to config file. The issue had multiple root causes:
1. Buffer size bug: HEXKEY_LEN constant was too small (64) for public key (needs 129)
2. Silent failure in bytes_to_hex() when buffer too small
3. Wrong validation length checks causing incorrect need_* detection
4. Keypair regeneration instead of deriving public key from private key
5. Node ID conditional logic bug inserting it only when private key was invalid
Changes:
- Added PRIV_HEXKEY_LEN (65) and PUB_HEXKEY_LEN (129) constants
- Added is_valid_priv_key() and is_valid_pub_key() with correct length checks
- Added sc_compute_public_key_from_private() to derive public key when possible
- Fixed node_id insertion logic to check need_node_id instead of need_priv_key
- Updated bytes_to_hex() to null-terminate on error
Tested with real config file - public key now correctly generates as 128 hex chars.
- Deleted 11 obsolete debug/isolation test files
- Restored test_pkt_normalizer.c from git repository
- Added test_ecc_encrypt and test_routing to Makefile (2 new functional tests)
- Removed settings.o from PN_OBJS (settings.c deleted)
- Added crc32.o to SC_LIB_OBJS and ETCP_OBJS to fix linker errors
- Removed unused routing_get_stats() function (undefined routing_stats_t type)
- Updated changelog with detailed cleanup summary
