From 76a56eb3b0fe82f77b1fb604dbf4a408e6ad7ba2 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Sat, 2 Nov 2013 15:57:36 +0200 Subject: mac80211_hwsim: Fix radiotap header for ACK frames The earlier addition of rt_tsft to struct hwsim_radiotap_hdr updated only mac80211_hwsim_monitor_tx() to fill in the new field. mac80211_hwsim_monitor_ack() did not set the rt_tsft field and as such, leaked eight bytes of kernel memory to user space. In addition, the resulting radiotap header is invalid since the field offsets do not match. Fix these issues by defining a separate radiotap header structure for the ACK frame case which does not use all the fields.

Since calibrations are notification from firmware and not Rx packets, this doesn't change anyway - the firmware will fire an interrupt straight away regardless of the interrupt coalescing value. Also, a HW issue has been discovered in 7000 devices series. The work around is to disable the new interrupt coalescing timeout feature - do this by setting bit 31 in CSR_INT_COALESCING. This has been fixed in 7265 which means that we can't rely on the device family and must have a hint in the iwl_cfg structure.

Since the firwmware wants it the opposite (first set the MAC context as unassoc, and only then, remove the STA of the API), we have a small period of time in which the STA in firmware doesn't have a valid ieee80211_sta pointer. During that time, iwl_mvm_vif->ap_sta_id, is still set to the STA in firmware that represent the AP.
