[PATCH] dvb-core/dvb_demux.c: Fix receiving invalid EIT-sections

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Signed-off-by: Johann Friedrichs <johann.friedrichs@xxxxxx>

Resetting buf without resetting pusi_seen at a channel-switch can lead
to copying the rest of a section to the start of buf, but treating it as
a complete section, when the next pusi arrives.
EIT-sections starting without valid header were randomly received during
an EIT-scan
on a transponder.
