From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Anderson Lizardo To: linux-bluetooth@vger.kernel.org Cc: Anderson Lizardo Subject: [PATCH BlueZ 1/5] scanparam: Fix handle range check on descriptor discovery Date: Mon, 29 Jul 2013 09:59:28 -0400 Message-Id: <1375106372-2255-1-git-send-email-anderson.lizardo@openbossa.org> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: When discovering descriptors, if there is only a single descriptor, the start handle will be equal to the end handle. It is valid to issue the Find Information Request on this case. Before this fix, notification for Scan Refresh characteristic was never enabled. --- profiles/scanparam/scan.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/profiles/scanparam/scan.c b/profiles/scanparam/scan.c index f5db5ed..0ad2e17 100644 --- a/profiles/scanparam/scan.c +++ b/profiles/scanparam/scan.c @@ -158,7 +158,7 @@ static void refresh_discovered_cb(GSList *chars, guint8 status, start = chr->value_handle + 1; end = scan->range.end; - if (start >= end) + if (start > end) return; scan->refresh_handle = chr->value_handle; -- 1.7.9.5
