From 52334b7fbbc58daeb79296841d74c04773ff174b Mon Sep 17 00:00:00 2001
From: Nick Lowe <nick.lowe@xxxxxxxxxxxx>
Date: Fri, 19 Feb 2016 14:50:34 +0000
Subject: [PATCH] Add rx_bytes64 and tx_bytes64 and populate these 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.
