'NL80211_STA_INFO_RX_DURATION' accounts for aggregate PPDU duration in microseconds for all the frames from a peer. Drivers can fill 'rx_duration' field and set the flag 'NL80211_STA_INFO_RX_DURATION'. 'rx_duration' will give an idea about the total time spent by our peer with each of its connected peers. Also extend 'PUT_SINFO' for supporting rx_duration field Signed-off-by: Mohammed Shafi Shajakhan --- include/net/cfg80211.h | 4 +++- include/uapi/linux/nl80211.h | 3 +++ net/wireless/nl80211.c | 3 ++- 3 files changed, 8 insertions(+), 2 deletions(-) diff --git a/include/net/cfg80211.h b/include/net/cfg80211.h index 0bbfbf3..e0fe16e 100644 --- a/include/net/cfg80211.h +++ b/include/net/cfg80211.h @@ -1063,11 +1063,12 @@ struct cfg80211_tid_stats { * @rx_beacon: number of beacons received from this peer * @rx_beacon_signal_avg: signal strength average (in dBm) for beacons received * from this peer + * @rx_duration: aggregate PPDU duration(usecs) for all the frames from a peer * @pertid: per-TID statistics, see &struct cfg80211_tid_stats, using the last * (IEEE80211_NUM_TIDS) index for MSDUs not encapsulated in QoS-MPDUs. */ struct station_info { - u32 filled; + u64 filled; u32 connected_time; u32 inactive_time; u64 rx_bytes; @@ -1106,6 +1107,7 @@ struct station_info { u32 expected_throughput; u64 rx_beacon; + u64 rx_duration; u8 rx_beacon_signal_avg; struct cfg80211_tid_stats pertid[IEEE80211_NUM_TIDS + 1]; }; diff --git a/include/uapi/linux/nl80211.h b/include/uapi/linux/nl80211.h index b2a8d8c..e11559f 100644 --- a/include/uapi/linux/nl80211.h +++ b/include/uapi/linux/nl80211.h @@ -2482,6 +2482,8 @@ enum nl80211_sta_bss_param { * TID+1 and the special TID 16 (i.e. value 17) is used for non-QoS frames; * each one of those is again nested with &enum nl80211_tid_stats * attributes carrying the actual values. + * @NL80211_STA_INFO_RX_DURATION: aggregate PPDU duration(usecs) for all the + * frames from a peer * @__NL80211_STA_INFO_AFTER_LAST: internal * @NL80211_STA_INFO_MAX: highest possible station info attribute */ @@ -2518,6 +2520,7 @@ enum nl80211_sta_info { NL80211_STA_INFO_BEACON_RX, NL80211_STA_INFO_BEACON_SIGNAL_AVG, NL80211_STA_INFO_TID_STATS, + NL80211_STA_INFO_RX_DURATION, /* keep last */ __NL80211_STA_INFO_AFTER_LAST, diff --git a/net/wireless/nl80211.c b/net/wireless/nl80211.c index d6c6449..3969d10 100644 --- a/net/wireless/nl80211.c +++ b/net/wireless/nl80211.c @@ -3753,7 +3753,7 @@ static int nl80211_send_station(struct sk_buff *msg, u32 cmd, u32 portid, goto nla_put_failure; #define PUT_SINFO(attr, memb, type) do { \ - if (sinfo->filled & BIT(NL80211_STA_INFO_ ## attr) && \ + if (sinfo->filled & (1ULL << NL80211_STA_INFO_ ## attr) && \ nla_put_ ## type(msg, NL80211_STA_INFO_ ## attr, \ sinfo->memb)) \ goto nla_put_failure; \ @@ -3779,6 +3779,7 @@ static int nl80211_send_station(struct sk_buff *msg, u32 cmd, u32 portid, PUT_SINFO(LLID, llid, u16); PUT_SINFO(PLID, plid, u16); PUT_SINFO(PLINK_STATE, plink_state, u8); + PUT_SINFO(RX_DURATION, rx_duration, u64); switch (rdev->wiphy.signal_type) { case CFG80211_SIGNAL_TYPE_MBM: -- 1.7.9.5
