From fc10d8a0818bb87001a64a72552ed28fe60931ee Mon Sep 17 00:00:00 2001 From: auric Date: Sat, 21 Feb 2026 14:59:07 -0600 Subject: Add A2S probing, sd-bus state, tail/broadcast, and bot audit log MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit State detection: - Add STATE_STOPPING to ProcessState enum - Replace system("systemctl is-active") with libsystemd sd-bus API for accurate starting/stopping/crashed state reporting; works for any unit type (RCON or STDIN) that declares a service: field - Implement real A2S_INFO UDP queries (src/console/a2s.c) for units with health.type = a2s (Valve games: TF2, GMod); differentiates running / hibernating (0 players) / changing_map (A2S down, RCON up) / unreachable; includes player count and map name in responses - Refactor probe_rcon_state() into probe_unit_state() returning a ProbeResult struct with state, players, max_players, map fields - status and list responses now include players/max_players/map fields New daemon commands: - tail : return ring buffer snapshot as a single response - broadcast : send broadcast_cmd-formatted message to all running units; works for both RCON and STDIN console types New YAML field: - broadcast_cmd: command template (e.g. "say {msg}") — opt-in per unit; units without it are skipped by broadcast CLI (umbrella-cli): - Add tail subcommand (non-interactive output snapshot) - Add broadcast subcommand - status shows Players and Map when available - list adds PLAYERS and MAP columns Bot (umbrella-bot): - Replace !attach / !detach with !tail (shows last 30 lines, no streaming) - Add !broadcast command - Write per-!cmd audit entries to /var/log/umbrella/bot-audit.log - !units and !status responses include player counts when available Co-Authored-By: Claude Sonnet 4.6 --- src/console/a2s.h | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 src/console/a2s.h (limited to 'src/console/a2s.h') diff --git a/src/console/a2s.h b/src/console/a2s.h new file mode 100644 index 0000000..c96e445 --- /dev/null +++ b/src/console/a2s.h @@ -0,0 +1,27 @@ +#ifndef A2S_H +#define A2S_H + +#include + +/* + * A2S_INFO query (Valve Source engine query protocol). + * Retrieves server information over UDP. + * + * Only used for units with health.type == HEALTH_A2S. + */ + +typedef struct { + int players; /* current player count */ + int max_players; /* server player limit */ + char map[64]; /* current map name */ +} A2SInfo; + +/* + * a2s_query: Send an A2S_INFO request and parse the response. + * + * Returns 0 on success with *out populated. + * Returns -1 on timeout, parse error, or any network failure. + */ +int a2s_query(const char *host, uint16_t port, int timeout_ms, A2SInfo *out); + +#endif /* A2S_H */ -- cgit v1.2.3
