AyeZeeBB ecb083f417 Don't drop every player after the server is held up 2026-10-04 17:56:24 -05:00
AyeZeeBB 3fddd1433a Trainer: quiet by default, host's setup for guests; drop the out-of-view cut
Follow-ups to the trainer (PR 37), and one multiplayer change.

Off until asked for (Extension/Trainer)
- The jump read-out and the LB+RB controller shortcuts start off. Jumps
  are logged only while the read-out or telemetry recording is on, and
  trick launches only when the trainer scaled them. A saved trainer.json
  keeps what the player chose.

Memory search on demand (trainer.cpp, trainer_classes.cpp)
- The search for the game's tuning classes reads all writable memory.
  It ran for every player after a level loaded, and up to seven times
  when it found nothing. It now runs only when a class value or the flip
  speed is not the game's own (the player's, or a host's they skate
  with) or the EVERYTHING list is open, and at most three times a level.
- For those players it runs again on each level, which brings fresh
  copies; a search from an earlier level used to count as done.

Guests under enforced physics
- A guest is locked by the session's enforce setting, from the moment
  of joining (Engine/Game/Multiplayer/session_physics.h), not by whether
  the enforcement status text was set yet.
- A guest's class values no longer come back after a map change.

The host's whole setup reaches its guests (protocol 39)
- Only Gameplay/SkatePhysicsTuning travelled, so a host could push,
  sprint or jump further than the guests it held to the game's own.
- New packet physics_extras (30): the host's class values, trick
  multipliers and auto push (trainer_session.h), sent when they change
  and to players who join later, taken from the host only. A dedicated
  server's are the game's own and it ignores the packet.
- Under enforcement a guest's own trick multipliers stand down for the
  host's, whatever the boosts switch says. With enforcement off nothing
  changes.
- A guest refuses bytes that are not an encoding, holds values to the
  trainer's own ranges, and leaves out class values written for another
  game build's table.
- protocol_version 38 -> 39: released versions disconnect from a peer
  that sends a packet they cannot decode.

Out-of-view players are posed every frame again (Session/session.cpp)
- Players outside the camera's view and past 8 m were sampled at 20 Hz
  (b763631). The game's replays record each skater as it stood every
  frame and their camera looks anywhere, so those players moved at
  20 Hz in replays. Removed; the distance rule (20 Hz past 200 m, 10 Hz
  past 350 m) stays. This gives back the client-tick time it saved on
  busy servers.

AyeZeeBB a7d95057ac Harden multiplayer against disruptive and spoofed traffic
Cap outfit packets and stop dropping recipients when a relay cannot be
built. Add per-player relay limits for outfits, skater sound and voice,
and a back-off for Steam IDs that keep failing to join.

Throwdowns: only participants can write rows, turns and scores; a copy
that fails to spawn no longer blocks the others.

Throttle remote skater and skateboard re-creation, cap remote objects
per session, and show developer and friend marks only for identities
Steam vouches for. Route all connections through Steam's relays.

Dedicated server: validate map changes, clean player names, keep vote
cooldowns across reconnects, and cut ban labels on a character boundary.

AyeZeeBB 984656150d Give the Linux server 64 bits of session entropy and a pinned Steam lib
Two follow-ups to the Linux server support in #6. Both are Linux-only, so
neither reached a Windows player.

Session codes
- nonce()'s fallback for a container with no /dev/urandom read
  "i < 4 && !value", which ended the loop as soon as the first round
  produced anything: one round of sixteen bits instead of four. Over
  200k draws that is 62k distinct codes with a ceiling of 0xffff, rather
  than 200k across the full range.

libsteam_api.so
- It was fetched from a mirror's main branch with no hash, by CI and by
  the script every server operator runs, and it is loaded into the
  server process. A branch name is whatever that branch holds on the day
  it runs.
- Pinned to mirror commit df2baabf574a and checked against its SHA-256
  (385840 bytes, eb2dd015...). The size and export checks already there
  catch a wrong file; a hash is what catches a swapped one.
- --sdk-url still overrides the URL and drops the check, since a
  different URL has a different hash; --sdk-sha256 keeps it.
