[PATCH BlueZ v2 0/4] Enhance GATT to pass PTS tests

[PATCH BlueZ v2 0/4] Enhance GATT to pass PTS tests

[Frédéric Danis]

The first patch allow to prevent automatic security level change to
allow to display the security error when running GATT/CL/GAR/BI-04-C
using btgatt-client.

The other patches add commands to be able to call GATT discovery
functions from btgatt-client and get their results.

v1 -> v2: Re-use att_send_op->retry and make it possible to prevent
            security upgrade on a per operation basis
          Remove "btgatt-client: Add function to search descriptors"
            as GATT/CL/GAD/BV-06-C test is optional
          Fix command arguments check in btgatt-client

Frédéric Danis (4):
  gatt: Prevent security level change for PTS GATT tests
  btgatt-client: Add function to search service based on UUID
  btgatt-client: Add function to search characteristics
  btgatt-client: Add function to search all primary services

[PATCH BlueZ v2 1/4] gatt: Prevent security level change for PTS GATT tests

[Frédéric Danis]

Some PTS GATT tests like GATT/CL/GAR/BI-04-C request to be able to get the
security error and do not try to change the security level.

This commit adds the ability to prevent to change the security level for
an operation.

[PATCH BlueZ v3 1/5] shared/gatt: Prevent security level change for PTS GATT tests

[Frédéric Danis]

Some PTS GATT tests like GATT/CL/GAR/BI-04-C request to be able to get the
security error and do not try to change the security level.

This commit adds the ability to prevent to change the security level for
an operation.

[PATCH BlueZ 1/5] gatt: Prevent security level change for PTS GATT tests

[Frédéric Danis]

Some PTS GATT tests like GATT/CL/GAR/BI-04-C request to be able to get the
security error and do not try to change the security level.

this commit adds a variable allowing to prevent to change the security
level.
