Subject: [PATCH] firedtv: correct version number and current/next in CA_PMT
Date: Mon, 1 Mar 2010 11:59:20 +0100 (CET) [thread overview]
Message-ID: <tkrat.dc97d52c76a2dc07@s5r6.in-berlin.de> (raw)
Date: Tue, 21 Jul 2009 18:45:50 +0200
From: Henrik Kurelid <henrik@kurelid.se>
The version number in the CA_PMT message sent to the hardware was
alwaysed set to zero. This could cause problems if the PMT would
change during decryption of a channel since the new CA_PMT would have
the same version number as the old. The version number is now copied
from the original PMT.

This patch got stuck somehow on the long way upstream. :-)
Would be good to get into one of the next .34-rc releases.
