When is_allowed is set to false, calling btd_service_connect and service_accept will fail and the existing service connection gets disconnected. Reviewed-by: Miao-chen Chou --- 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 | 39 +++++++++++++++++++++++++++++++++++++++ src/service.h | 2 ++ 2 files changed, 41 insertions(+) diff --git a/src/service.c b/src/service.c index 21a52762e637..929d6c136b6d 100644 --- a/src/service.c +++ b/src/service.c @@ -41,6 +41,7 @@ struct btd_service { void *user_data; btd_service_state_t state; int err; + bool is_allowed; }; struct service_state_callback { @@ -133,6 +134,7 @@ struct btd_service *service_create(struct btd_device *device, service->device = device; /* Weak ref */ service->profile = profile; service->state = BTD_SERVICE_STATE_UNAVAILABLE; + service->is_allowed = true; return service; } @@ -186,6 +188,18 @@ int service_accept(struct btd_service *service) if (!service->profile->accept) return -ENOSYS; + if (!service->is_allowed) { + info("service %s is not allowed", + service->profile->remote_uuid); + return -ECONNABORTED; + } + + if (!service->is_allowed) { + info("service %s is not allowed", + service->profile->remote_uuid); + return -ECONNABORTED; + } + err = service->profile->accept(service); if (!err) goto done; @@ -245,6 +259,12 @@ int btd_service_connect(struct btd_service *service) return -EBUSY; } + if (!service->is_allowed) { + info("service %s is not allowed", + service->profile->remote_uuid); + return -ECONNABORTED; + } + err = profile->connect(service); if (err == 0) { change_state(service, BTD_SERVICE_STATE_CONNECTING, 0); @@ -361,6 +381,25 @@ bool btd_service_remove_state_cb(unsigned int id) return false; } +void btd_service_set_allowed(struct btd_service *service, bool allowed) +{ + if (allowed == service->is_allowed) + return; + + service->is_allowed = allowed; + + if (!allowed && (service->state == BTD_SERVICE_STATE_CONNECTING || + service->state == BTD_SERVICE_STATE_CONNECTED)) { + btd_service_disconnect(service); + return; + } +} + +bool btd_service_is_allowed(struct btd_service *service) +{ + return service->is_allowed; +} + void btd_service_connecting_complete(struct btd_service *service, int err) { if (service->state != BTD_SERVICE_STATE_DISCONNECTED && diff --git a/src/service.h b/src/service.h index 88530cc17d53..5a2a02447b24 100644 --- a/src/service.h +++ b/src/service.h @@ -51,6 +51,8 @@ int btd_service_get_error(const struct btd_service *service); unsigned int btd_service_add_state_cb(btd_service_state_cb cb, void *user_data); bool btd_service_remove_state_cb(unsigned int id); +void btd_service_set_allowed(struct btd_service *service, bool allowed); +bool btd_service_is_allowed(struct btd_service *service); /* Functions used by profile implementation */ void btd_service_connecting_complete(struct btd_service *service, int err);
