Hi,
These are the first steps in the direction of making GATT a first
class citizen in Bluez.
For this, the first step is to move the primary service discovery
procedure to the core bluetoothd. For that we needed to move a lot of
code around, and add a few features, for example, we now are able to
store the remote device type and restore it from storage, it is useful
when deciding which medium should be used for service discovery.
While doing this, I noticed something that could cause some confusion:
in the Attribute API, both the Device Service hierarchy
([prefix]/{hci0}/{device0}/{service0}) and the Device Characteristic
([prefix]/{hci0}/{device0}/{service0}/{characteristic0}) have the same
Interface name (org.bluez.Characteristic). Is that on purpose?
Cheers,

I've finished pushing all the patches in this set to the upstream tree.
Please double check that I didn't miss anything.

Pushed upstream. Thanks.

As the primary services were discovered by the core bluetoothd, we need
a way to export that information.
The service discovery uses the same primary list as the device, there's no
need to free that list when the discovery finishes. That list will be removed
when the device is free'd.

I tried to continue applying the patches starting with this one, but it
doesn't apply cleanly anymore probably due to me skipping patch 7 with
its compilation errors. So I'll once again stop processing the patch set
here.

If you're gonna do typecasting to GFunc (something which btw should be
avoided whenever possible) you might as well pass g_free directly and
not create any dedicated function for it.

Most of your patches listed here are at a higher level than what I am
currently looking at, so I am just very happy that they are getting
done.
So all of my comments of your patch list are here.

As I have mentioned previously, I am interested in assuring support of
LE Privacy. This is something we saw for the first time at the
Barcelona UPF, which caused a few teams problems.
While I understand that for now you just want to get Public Addressing
working, I think we may want to include a framework which allows for
Ransom and private addressing in the future, even if for now they are
just place-holders.
Towards that end, any interface like bt_io_connect which is specifying
the Source and Destination address in this manner, should also include
the address type, which at a minimum will need to be stored with the
Destination BDADDR. Source address type is less of a concern, as the
lower kernel layers can probably derive it. But I would suggest a
connect parameter of:
BT_IO_OPT_DEST_BDADDR_TYPE
with possible values of
0x00 - Public
0x01 - Random
And a gatt structure member of something like "uint8_t dbat".

Yes, doc/attribute-api.txt should contain the documentation of the DBus API.

Is there a simple text file anywhere yet, that details the up-to-date
Object-Path/Interface/Method/Properties/etc DBus API layout of the LE
additions?

As the primary services were discovered by the core bluetoothd, we need
a way to export that information.
The service discovery uses the same primary list as the device, there's no
need to free that list when the discovery finishes. That list will be removed
when the device is free'd.

Most of this functionality was moved to src/device.c. Since that move
this code doesn't work. Some ugly hack were added to avoid breaking

Because we need to know the device type (LE, Basic Rate or Dual Mode)
to be able to fully restore the device from storage, we have to store
and load this information to permanent storage.
Note: due to "device_type_t" usage in storage.h, some header includes
needed to be reordered in files which include storage.h.
