Subject: [PATCH 4.15 50/53] Bluetooth: Fix connection if directed advertising and privacy is used
Date: Tue, 17 Apr 2018 17:59:15 +0200 [thread overview]
Message-ID: <20180417155725.492491832@linuxfoundation.org> (raw)
In-Reply-To: <20180417155723.091120060@linuxfoundation.org>
4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Szymon Janc <szymon.janc@codecoup.pl>
commit 082f2300cfa1a3d9d5221c38c5eba85d4ab98bd8 upstream.
Local random address needs to be updated before creating connection if
RPA from LE Direct Advertising Report was resolved in host. Otherwise
remote device might ignore connection request due to address mismatch.
This was affecting following qualification test cases:
GAP/CONN/SCEP/BV-03-C, GAP/CONN/GCEP/BV-05-C, GAP/CONN/DCEP/BV-05-C
