From c8ef465e10f46fd017cc9c3e455cc368a2b9da2b Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Fri, 6 Dec 2019 18:17:06 +0100 Subject: [PATCH] hostapd: expose beacon reports through ubus Subscribe to beacon reports through ubus. Can be used for hearing map and client steering purposes. First enable rrm: ubus call hostapd.wlan0 bss_mgmt_enable '{"beacon_report":True}' Subscribe to the hostapd notifications via ubus. Request beacon report: ubus call hostapd.wlan0 rrm_beacon_req '{"addr":"00:xx:xx:xx:xx:xx", "op_class":0, "channel":1, "duration":1,"mode":2,"bssid":"ff:ff:ff:ff:ff:ff", "ssid":""}' Signed-off-by: Nick Hainke [rework identation] Signed-off-by: David Bauer --- .../hostapd/patches/600-ubus_support.patch | 12 +++++++++ .../services/hostapd/src/src/ap/ubus.c | 26 +++++++++++++++++++ .../services/hostapd/src/src/ap/ubus.h | 13 ++++++++++ 3 files changed, 51 insertions(+) diff --git a/package/network/services/hostapd/patches/600-ubus_support.patch b/package/network/services/hostapd/patches/600-ubus_support.patch index 6842c0e63e6a..b2860780eb25 100644 --- a/package/network/services/hostapd/patches/600-ubus_support.patch +++ b/package/network/services/hostapd/patches/600-ubus_support.patch @@ -458,3 +458,15 @@ case 'o': params.override_driver = optarg; break; +--- a/src/ap/rrm.c ++++ b/src/ap/rrm.c +@@ -89,6 +89,9 @@ static void hostapd_handle_beacon_report + return; + wpa_msg(hapd->msg_ctx, MSG_INFO, BEACON_RESP_RX MACSTR " %u %02x %s", + MAC2STR(addr), token, rep_mode, report); ++ if (len < sizeof(struct rrm_measurement_beacon_report)) ++ return; ++ hostapd_ubus_notify_beacon_report(hapd, addr, token, rep_mode, (struct rrm_measurement_beacon_report*) pos, len); + } + + diff --git a/package/network/services/hostapd/src/src/ap/ubus.c b/package/network/services/hostapd/src/src/ap/ubus.c index 988cc7011313..5b1681254829 100644 --- a/package/network/services/hostapd/src/src/ap/ubus.c +++ b/package/network/services/hostapd/src/src/ap/ubus.c @@ -1271,3 +1271,29 @@ void hostapd_ubus_notify(struct hostapd_data *hapd, const char *type, const u8 * ubus_notify(ctx, &hapd->ubus.obj, type, b.head, -1); } + +void hostapd_ubus_notify_beacon_report( + struct hostapd_data *hapd, const u8 *addr, u8 token, u8 rep_mode, + struct rrm_measurement_beacon_report *rep, size_t len) +{ + if (!hapd->ubus.obj.has_subscribers) + return; + + if (!addr || !rep) + return; + + blob_buf_init(&b, 0); + blobmsg_add_macaddr(&b, "address", addr); + blobmsg_add_u16(&b, "op-class", rep->op_class); + blobmsg_add_u16(&b, "channel", rep->channel); + blobmsg_add_u64(&b, "start-time", rep->start_time); + blobmsg_add_u16(&b, "duration", rep->duration); + blobmsg_add_u16(&b, "report-info", rep->report_info); + blobmsg_add_u16(&b, "rcpi", rep->rcpi); + blobmsg_add_u16(&b, "rsni", rep->rsni); + blobmsg_add_macaddr(&b, "bssid", rep->bssid); + blobmsg_add_u16(&b, "antenna-id", rep->antenna_id); + blobmsg_add_u16(&b, "parent-tsf", rep->parent_tsf); + + ubus_notify(ctx, &hapd->ubus.obj, "beacon-report", b.head, -1); +} diff --git a/package/network/services/hostapd/src/src/ap/ubus.h b/package/network/services/hostapd/src/src/ap/ubus.h index 27acd32659d5..e16017394fd8 100644 --- a/package/network/services/hostapd/src/src/ap/ubus.h +++ b/package/network/services/hostapd/src/src/ap/ubus.h @@ -26,6 +26,7 @@ struct hostapd_ubus_request { struct hostapd_iface; struct hostapd_data; struct hapd_interfaces; +struct rrm_measurement_beacon_report; #ifdef UBUS_SUPPORT @@ -45,6 +46,10 @@ void hostapd_ubus_free_bss(struct hostapd_data *hapd); int hostapd_ubus_handle_event(struct hostapd_data *hapd, struct hostapd_ubus_request *req); void hostapd_ubus_notify(struct hostapd_data *hapd, const char *type, const u8 *mac); +void hostapd_ubus_notify_beacon_report(struct hostapd_data *hapd, + const u8 *addr, u8 token, u8 rep_mode, + struct rrm_measurement_beacon_report *rep, + size_t len); void hostapd_ubus_add(struct hapd_interfaces *interfaces); void hostapd_ubus_free(struct hapd_interfaces *interfaces); @@ -78,6 +83,14 @@ static inline void hostapd_ubus_notify(struct hostapd_data *hapd, const char *ty { } +static inline void hostapd_ubus_notify_beacon_report(struct hostapd_data *hapd, + const u8 *addr, u8 token, + u8 rep_mode, + struct rrm_measurement_beacon_report *rep, + size_t len) +{ +} + static inline void hostapd_ubus_add(struct hapd_interfaces *interfaces) { } -- 2.30.2
