2022-10-11	audio: prevent an integer overflow in resampling code	Volker Rümelin	1	-5/+6
	There are corner cases where rate->opos can overflow. For example, if QEMU is started with -audiodev pa,id=audio0, out.frequency=11025 -device ich9-intel-hda -device hda-duplex, audiodev=audio0 and the guest plays audio with a sampling frequency of 44100Hz, rate->opos will overflow after 27.05h and the audio stream will be silent for a long time. To prevent a rate->opos and also a rate->ipos overflow, both are wrapped around after a short time. The wrap around point rate->ipos >= 0x10001 is an arbitrarily selected value and can be any small value, 0 and 1 included. The comment that an ipos overflow will result in an infinite loop has been removed, because in this case the resampling code only generates no more output samples and the audio stream stalls. However, there is no infinite loop. Signed-off-by: Volker Rümelin <vr_qemu@t-online.de> Message-Id: <20220923183640.8314-12-vr_qemu@t-online.de> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2017-07-17	audio: st_rate_flow exist a infinite loop	Peng Hao	1	-0/+6
	If a voice recording equipment is opened for a long time(several days) in windows guest, rate->ipos will overflow and rate->opos will never have a chance to change. It will result to a infinite loop.
