Return-Path: From: Andrzej Kaczmarek To: linux-bluetooth@vger.kernel.org Cc: Andrzej Kaczmarek Subject: [PATCH v2] Bluetooth: Fix powering on with privacy and advertising Date: Sun, 22 Nov 2015 21:42:21 +0100 Message-Id: <1448224941-834-1-git-send-email-andrzej.kaczmarek@codecoup.pl> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: In order to enable advertising with privacy enabled, SMP has to be registered in order to generate new RPA. During power on, it will be registered at the very end which is the reason why advertising is not enabled and it's not possible to enable it anymore due to mismatch between hci_dev settings and actual controller state. This fixes this problem by moving SMP registration earlier, just after controller is powered (which is ok, because LE SMP will be already able to decide on identity address to be used), but before advertising is enabled. --- net/bluetooth/mgmt.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/net/bluetooth/mgmt.c b/net/bluetooth/mgmt.c index dc8e428..e8a2f8b 100644 --- a/net/bluetooth/mgmt.c +++ b/net/bluetooth/mgmt.c @@ -7305,13 +7305,6 @@ static void powered_complete(struct hci_dev *hdev, u8 status, u16 opcode) BT_DBG("status 0x%02x", status); if (!status) { - /* Register the available SMP channels (BR/EDR and LE) only - * when successfully powering on the controller.
