[pulseaudio-discuss] Possible bug in pa_sink_input_request_rewind

[Alexander E. Patrakov]

Hello.

In pa_sink_input_request_rewind, nbytes == 0 means "rewind as far as
possible". However, I think I have found (by code inspection) a case
where it is not honored. The case is where
i->thread_info.rewrite_nbytes is already non-zero due to a prior
rewind request.

In this case, nbytes will be set to i->thread_info.rewrite_nbytes (a
non-zero value) and thus the later test for nbytes <= 0 will fail.
BTW, the "<=" is misleading, as nbytes is unsigned.

No patch yet, as I should not create patches at night.
