Reviewed-by: Miao-chen Chou --- Changes in v9: - Fix gitlint error in patch 'core: add device callbacks to adapter driver' Changes in v8: - Remove changes in profiles/health/ Changes in v7: - Fix compiler errors in profiles/hdp.c Changes in v6: - include instead of in plugins/admin.c Changes in v5: - Fix compiler errors in plugins/admin.c Changes in v4: - Update commit message (admin_policy -> admin) - remove old plugins/admin_policy.c Changes in v3: - Rename plugins/admin_policy.c -> plugins/admin.c - Use device_added callback in btd_adapter_driver instead of listen for dbus - Add authorization method in profiles/health/mcap.c and block incoming connections in adapter authorization function. Changes in v2: - Move bt_uuid_hash and bt_uuid_equal functions to adapter.c. - Modify the criteria to say a device is `Affected` from any-of-uuid to any-of-auto-connect-profile. - Remove the code to remove/reprobe disallowed/allowed profiles, instead, check if the service is allowed in bt_io_accept connect_cb. - Fix a typo in emit_property_change in plugin/admin_policy.c:set_service_allowlist - Instead of using device_state_cb, utilize D-BUS client to watch device added/removed. - Add a document in doc/ src/service.c | 33 +++++++++++++++++++++++++++++++++ src/service.h | 2 ++ 2 files changed, 35 insertions(+) diff --git a/src/service.c b/src/service.c index 21a52762e637..84fbb208a7e9 100644 --- a/src/service.c +++ b/src/service.c @@ -41,6 +41,7 @@ struct btd_service { void *user_data;

Each system profile asks adapter authorization when seeing a incoming connection. 2. Each external profile checks if its UUID is allowed by adapter when seeing a incoming connection. --- The following test steps were performed after enabling admin plugin: 1. Set ServiceAllowList to ["1234"]. 2. Turn on a paired classic keyboard. Verify it can not be connected. 3. Set ServiceAllowList to ["1800","1801","180A","180F","1812"] 4. Turn off and turn on the keyboard. Verift it can be connected.

It is necessary for implementation of "AffectedByPolicy" property since it needs to register an interface for each device object and unregister it once the device gets removed. --- The following test steps were performed: 1. start discovery using UI 2. verify device_data were added by checking system log 3. stop discovery 4. verify device_data were removed after a few seconds by checking system log (no changes since v8) Changes in v8: - add device_data when we get called device_resolved instead of device_added. Otherwise it is possible that a device service has not yet been resolved so device_data->|affected| might not be correct.
