PS1, Line 1661: send_ul_rtp_packet(lchan, fn, bfi, 0);
well if len = 0, then it makes no sense to access to
buffer, so it shouldn't expect it to be non-nul […]
I just double-checked to be
absolutely sure: when OsMux is used, the call boils down to osmo_rtp_build() in
libosmo-netif, and in the non-OsMux case it boils down to rtp_session_create_packet() in
the external-dependency ortp library. Both functions are explicitly OK with zero-length
RTP payloads (length argument to the function equals 0), and in both functions the
memcpy() call for payload bytes is explicitly skipped in the zero-length case, thus the
data pointer argument is never used. So we all good.
