durch 1386a49a99 Add forward_timeout to LP client config 
Add forward_timeout (30s default) to LpConfig and wrap send_forward_packet's
connect_send_receive call with tokio::time::timeout, matching the pattern
used by register() with registration_timeout.

This prevents indefinite hangs when forwarding packets through entry gateway.
 2026-01-08 15:45:13 +00:00
durch bb76ff82bd Add LpConfig struct and AIDEV-NOTE documentation for KKT+PSQ 
- Create config.rs with LpConfig struct (kem_algorithm, psk_ttl, enable_kkt)
- Export LpConfig from lib.rs
- Add AIDEV-NOTE to psk.rs explaining:
  - Why PSQ is embedded in Noise (single round-trip, PSK binding)
  - KEM migration path (X25519 → MlKem768 → XWing)
- Add AIDEV-NOTE to state_machine.rs explaining protocol flow:
  - KKTExchange → Handshaking → Transport state transitions
  - PSK derivation formula (ECDH || PSQ || salt)
 2026-01-08 15:45:13 +00:00
durch b5f1bab87b Deduplicate outer_key lookup pattern in nested_session.rs 
Extract common state_machine.session().ok().and_then(...) pattern into
two helper methods:
- get_send_key() for encryption (outer_aead_key_for_sending)
- get_recv_key() for decryption (outer_aead_key)

Updated 6 call sites to use the helpers, reducing verbosity.
 2026-01-08 15:45:13 +00:00
durch e096ec9c9e Use explicit bincode Options helper in nested_session 
Add bincode_options() helper that returns DefaultOptions with explicit
big_endian and varint_encoding configuration. This future-proofs against
bincode 1.x/2.x default changes and makes serialization format explicit.

Updated all 4 bincode usages in nested_session.rs to use the helper.
 2026-01-08 15:45:13 +00:00
durch d09e7a296d Return error on session unavailable in handle_subsession_packet 
Replace .session().ok() with proper error handling to fail fast when
session is Closed or Processing after state machine processing.

Previously, the code silently continued with outer_key = None, which
could cause protocol errors downstream.

Closes: nym-8de0
 2026-01-08 15:45:13 +00:00
durch 4e8411a728 Add semaphore-based connection limiting for LP packet forwarding 
Limits concurrent outbound connections when forwarding LP packets to
prevent file descriptor exhaustion under high load.

Key changes:
- Add max_concurrent_forwards config (default 1000)
- Add forward_semaphore to LpHandlerState
- Acquire semaphore permit before connecting in handle_forward_packet
- Return "Gateway at forward capacity" error when at limit

This provides load signaling so clients can choose another gateway
when the current one is overloaded.

Design note: Connection pooling was considered but provides minimal
benefit since telescope setup is one-time and targets are distributed
across many different gateways. See AIDEV-NOTE in LpHandlerState for
full analysis.

Closes: nym-xi3m
 2026-01-08 15:45:13 +00:00
durch 70311da0a6 Fix Zeroizing deref in ed25519 to_x25519 conversion 
The from_bytes() function expects &[u8], need to deref the Zeroizing
wrapper to get the inner array.
 2026-01-08 15:45:13 +00:00
durch bfd8eb3f2d Return Result from KCP session input() for error detection 
Change KcpSession::input() to return Result<(), KcpError> so callers
can detect invalid packets instead of silently ignoring them.

- Add ConvMismatch error variant for conversation ID mismatches
- Update driver to propagate errors from session.input()
- Update all test and example callers

Closes: nym-n0kk
 2026-01-08 15:45:13 +00:00
durch dcf5840b11 Zeroize Ed25519 key material in to_x25519 conversion 
Wrap hash and x25519_bytes in zeroize::Zeroizing to ensure private
key material is cleared from memory after use.

Closes: nym-k55g
 2026-01-08 15:45:12 +00:00
durch 9bcae469fc Increase KCP fragment limit from u8 to u16 
- Change frg field from u8 to u16 in packet header (25 bytes total)
- Update encode/decode to use get_u16_le/put_u16_le
- Update Segment struct frg field to u16
- Remove truncating cast in session.rs
- Max message size now ~91MB (65,535 fragments × MTU)
- Internal protocol only, no interop concerns

Nym uses KCP for reliability and multiplexing, not standard real-time
use cases. The u8 limit (255 fragments, ~355KB) was insufficient.

 2026-01-08 15:45:12 +00:00
durch 65bd47f342 Add gateway-probe localnet mode with WireGuard tunnel support 
Adds localnet testing mode to gateway-probe for LP development:
- Add TestMode enum for different probe configurations
- Add --gateway-ip flag for direct gateway testing
- Implement two-hop WireGuard tunnel for localnet
- Add mock ecash support for testing without real credentials
- Add netstack Go bindings for userspace networking
- Restructure probe with mode and common modules
- Update README with localnet mode documentation
 2026-01-08 15:45:12 +00:00
durch 637459b153 Add LP telescoping with nested sessions and subsession support 
Extends LP protocol with telescoping architecture for nested sessions:
- Add nested session support with KKpsk0 rekeying
- Add subsession support with collision detection
- Implement unified packet format with outer header
- Refactor gateway handlers for single-packet forwarding
- Add TTL-based state cleanup for stale sessions
- Add outer AEAD encryption layer
- Refactor registration client for packet-per-connection model
 2026-01-08 15:45:11 +00:00
durch 0a6f78a921 Implement LP registration protocol with KKT/PSQ integration 
Initial implementation of the Lewes Protocol (LP) for gateway registration:
- Add nym-lp crate with Noise protocol handshake
- Add LP listener to gateway for handling registrations
- Add LP client for registration flow
- Integrate KKT for post-quantum KEM key exchange
- Integrate PSQ for post-quantum PSK derivation
- Add Ed25519 authentication throughout
- Add docker/localnet support for testing
