Hi all,
This patch series is basically a rebased version of the previous RFC v3 series.
Claudio is going to send user-space patches in a few minutes.
This series depends on "[PATCH] Bluetooth: Remove useless code in hci_connect"
already sent to this ML.
Regards,
Andre
Andre Guedes (8):
Bluetooth: Move address type macros to bluetooth.h
Bluetooth: Rename link_to_mgmt to link_to_bdaddr
Bluetooth: Rename mgmt_to_le to bdaddr_to_le
Bluetooth: Add address type to struct sockaddr_l2
Bluetooth: Move bdaddr_to_le to hci_core
Bluetooth: Add dst_type parameter to hci_connect
Bluetooth: Use address type info from user-space
Bluetooth: Remove advertising cache

so I have applied all 8 patches to bluetooth-next tree now.

I did a brief read-through the patches and I fine with it. However
before I am going to commit any of these patches, I like to have
reviewed by Johan in detail at least.

I am warming up to this naming. Does anybody have any objections?

User-space pass the remote device address type to kernel through
struct sockaddr_l2 what makes the advertising useless. This patch
removes all advertising cache code.

In order to establish a LE connection we need the address type
information. User-space already pass this information to kernel
through struct sockaddr_l2.
This patch adds the dst_type parameter to l2cap_chan_connect so we
are able to pass the address type info from user-space down to
hci_conn layer.

This patch adds the dst_type parameter to hci_connect function.
Instead of searching the address type in advertising cache, we
use the dst_type parameter to establish LE connections.
The dst_type is ignored for BR/EDR connection establishment.

This patch adds the address type info to struct sockaddr_l2 so
user-space can inform the remote device address type required
to establish LE connections.
Soon, instead of looking the advertising cache up to discover the
address type, we'll use this address type info to establish LE
connections.

Since address type macros are not only related to Management
Interface anymore, it makes sense to rename the helper function

used by management interface and Bluetooth socket interface. It also
replaces the macro prefix MGMT_ADDR_ by BDADDR_.
