I have discovered a bug in the 1.11 RTPProxy Module when using IPv6 addressing.
When the command to RTPProxy is discovered to contain an IPv6 address in
"rtpproxy.c" function:
"int force_rtp_proxy_body(struct sip_msg* msg, struct force_rtpp_args *args,
pv_spec_p var)"
The option "6" is appended to the options being passed to RTP Proxy, however
the length component within the I/O vector is not increased.
Therefore the option is not detected by the RTPProxy process and the IPv6 is
not preloaded which can result in an RTP Proxy deadlock.
@Line 3725 (rtpproxy.c)
/* XXX must compare address families in all addresses */
if (pf == AF_INET6) {
if (append_opts(&opts, '6') == -1) {
LM_ERR("out of pkg memory\n");
goto error;
}
==> //DAVES - Accommodate new opts length
==> v[1].iov_len++;
}
I have currently added the above change to my opensips source code in order to
work past this problem.
Regards.
Dave
