From 39adbffe4b16285c54016d3e64471396354ae49f Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Thu, 20 Mar 2014 08:18:14 +0200 Subject: Bluetooth: Fix passkey endianess in user_confirm and notify_passkey The passkey_notify and user_confirm functions in mgmt.c were expecting different endianess for the passkey, leading to a big endian bug and sparse warning in recently added SMP code. This patch converts both functions to expect host endianess and do the conversion to little endian only when assigning to the mgmt event struct.

The code was previously trying to handle this for the mgmt_pair_device response (which worked well enough) but this is not the only connection related event that might be sent to user space before pairing is successful: another important event is Device Disconnected. The issue can actually be solved more simply than the solution previously used for mgmt_pair_device. Since we do have the identity address tracked as part of the remote IRK struct we can just copy it over from there to the hci_conn struct once we've for real sent the mgmt event for the new IRK.

The driver uses just one TX queue, and declare to mac80211 to support just one queue, but it allocates coherent memory for all queues. Furthermore the TX is code is written assumimg four queues exists, and even if we decide to enable more queues in future, its mapping rule to mac80211 is fixed. This means we have memory waste on rtl8180/rtl8185, and we have also not enough flexibility to add support for boards (rtl8187se) that will use more queues. This patch changes things in order to allocate coherent memory only for the queues effectively used and it make it possible to specify how to map hardware queues on mac80211 queues, that will be used by rtl8187se code as soon it will be merged. Note: even if the beacon queue is currently unused, this should change, so I kept it. Signed-off-by: Andrea Merello Signed-off-by: John W.
