From: Luiz Augusto von Dentz Date: Tue, 10 Mar 2020 09:59:07 -0700 Subject: input: hog: Attempt to set security level if not bonded Origin: https://git.kernel.org/pub/scm/bluetooth/bluez.git/commit?id=35d8d895cd0b724e58129374beb0bb4a2edf9519 This attempts to set the security if the device is not bonded, the kernel will block any communication on the ATT socket while bumping the security and if that fails the device will be disconnected which is better than having the device dangling around without being able to communicate with it until it is properly bonded. --- profiles/input/hog.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) diff --git a/profiles/input/hog.c b/profiles/input/hog.c index dfac689219a0..f0226ebbd1ba 100644 --- a/profiles/input/hog.c +++ b/profiles/input/hog.c @@ -49,6 +49,8 @@ #include "src/shared/util.h" #include "src/shared/uhid.h" #include "src/shared/queue.h" +#include "src/shared/att.h" +#include "src/shared/gatt-client.h" #include "src/plugin.h" #include "suspend.h" @@ -187,8 +189,15 @@ static int hog_accept(struct btd_service *service) } /* HOGP 1.0 Section 6.1 requires bonding */ - if (!device_is_bonded(device, btd_device_get_bdaddr_type(device))) - return -ECONNREFUSED; + if (!device_is_bonded(device, btd_device_get_bdaddr_type(device))) { + struct bt_gatt_client *client; + + client = btd_device_get_gatt_client(device); + if (!bt_gatt_client_set_security(client, + BT_ATT_SECURITY_MEDIUM)) { + return -ECONNREFUSED; + } + } /* TODO: Replace GAttrib with bt_gatt_client */ bt_hog_attach(dev->hog, attrib); -- 2.20.1
