Subject: [Bluez PATCH v1 10/14] plugins/admin_policy: add ServiceAllowList property
Date: Thu,  8 Jul 2021 14:23:10 +0800	[thread overview]
Message-ID: <20210708142059.Bluez.v1.10.I00fd6c348e4c93501de6de0eae0d23436fd3895b@changeid> (raw)
In-Reply-To: <20210708062314.245754-1-howardchung@google.com>

From: Yun-Hao Chung <howardchung@chromium.org>

This adds code to register interface org.bluez.AdminPolicyStatus.
The interface will provide read-only properties to indicate the current
settings of admin policies. We separate this from AdminPolicySet so that
normal clients can check current policy settings while only a few
clients can change policies.

This patch also adds readonly property ServiceAllowlist to
AdminPolicyStatus1, which indicates the current setting of service
allowlist.

Reviewed-by: Miao-chen Chou <mcchou@chromium.org>

The following test steps were performed:
1. Set ServiceAllowList to ["1124","180A","180F","1812"]
2. Verify ServiceAllowList is ["1124","180A","180F","1812"] in UUID-128
   form
3. Set ServiceAllowList to []
4. Verify ServiceAllowList is []
