Subject: [Bluez PATCH v1 03/14] core: add is_allowed property in btd_service
Date: Thu, 8 Jul 2021 14:23:03 +0800 [thread overview]
Message-ID: <20210708142059.Bluez.v1.3.Ic71b1ed97538a06d02425ba502690bdab1c5d836@changeid> (raw)
In-Reply-To: <20210708062314.245754-1-howardchung@google.com>
From: Yun-Hao Chung <howardchung@chromium.org>
This adds is_allowed property in btd_service. When is_allowed is set to
false, calling btd_service_connect and service_accept will fail and the
existing service connection gets disconnected.
