As a receiver, I fail to update srtp keys with MKI using the srtp_stream_update
This is new to master, this works fine with version 2.6.0

scenario:

  1. init srtp with ssrc_any_inbound, use_mki is true
  2. try to unprotect a packet with ssrc0 and associated mki0 => failure
  3. add srtp key with matching mki0 => success
  4. try to unprotect a packet with ssrc0 and associated mki0 => success
  5. try to unprotect a packet with ssrc1 and associated mki1 => failure
  6. add srtp key with matching mki1 => failure
  7. update srtp with srtp key with matching mki1 => failure

I suspect the bug to be around update_template_stream_cb or srtp_stream_remove.

srtp_unprotect creates a new stream with srtp_stream_clone, ssrc is stored in network order


static bool update_template_stream_cb(srtp_stream_t stream, void *raw_data)
{
    struct update_template_stream_data *data =
        (struct update_template_stream_data *)raw_data;
    srtp_t session = data->session;
    uint32_t ssrc = stream->ssrc; // ssrc is in network order
...


    /* remove stream */
    data->status = srtp_stream_remove(session, ssrc);
    if (data->status) {
        return false;
    }

but then, srtp_strp_remove expect ssrc to be given in host order

so possible fix can be to replace the call in update_template_stream_cb to be consistent with the changes made in the API:
data->status = srtp_stream_remove(session, ntohl(ssrc));

Thanks for reporting this, there was always a chance changing the API would break something but I think have a consistent public API is worth it. I have approved the PR but I also found another occurrence of this issue. I plan to add a test for this, so will get this issue open until the test is added.
