Subject: [PATCH v2 2/4] Bluetooth: Fix updating connection state to BT_CONNECT too early
Date: Fri, 28 Feb 2014 12:54:15 +0200	[thread overview]
Message-ID: <1393584857-30375-3-git-send-email-johan.hedberg@gmail.com> (raw)
In-Reply-To: <1393584857-30375-1-git-send-email-johan.hedberg@gmail.com>

From: Johan Hedberg <johan.hedberg@intel.com>

We shouldn't update the hci_conn state to BT_CONNECT until the moment
that we're ready to send the initiating HCI command for it. If the
connection has the BT_CONNECT state too early the code responsible for
updating the local random address may incorrectly think there's a
pending connection in progress and refuse to update the address.
