Make rx_bytes & tx_bytes 64-bit rather than 32-bit and
populate using NL80211_STA_INFO_RX_BYTES64 and NL80211_STA_INFO_TX_BYTES64
where support for these are available. This resolves the race vulnerable
32-bit value wrap/overflow. Rework RADIUS accounting to use these for
Acct-Input-Octets, Acct-Input-Gigawords, Acct-Output-Octets and
Acct-Output-Gigawords, these values are often used for billing purposes.

From 3d2766ddc4ead1a2dbcb22a81e47b5c5101f3275 Mon Sep 17 00:00:00 2001
From: Nick Lowe <nick.lowe@xxxxxxxxxxxx>
Date: Fri, 19 Feb 2016 10:22:32 +0000
Subject: [PATCH] Make rx_bytes & tx_bytes 64-bit rather than 32-bit and
populate using NL80211_STA_INFO_RX_BYTES64 and NL80211_STA_INFO_TX_BYTES64
where support for these are available. This resolves the race vulnerable
32-bit value wrap/overflow. Rework RADIUS accounting to use these for
Acct-Input-Octets, Acct-Input-Gigawords, Acct-Output-Octets and
Acct-Output-Gigawords, these values are often used for billing purposes.
