[Devel] QOP workaround in uac_auth() doesn't work around...

[Thomas Gelf]

Hi all,

I finally found some time to prepare the migration of our VoIP platform
to OpenSER 1.2. As I have seen there has been introduced my proposed
"workaround" (to just go on and don't let the call fail :o) for qop in
uac_auth:

Atm in 1.2 it's done like this:

 > switch (state)
 > {
 >   case QOP_STATE:
 >     /* TODO - add qop support */
 >     auth->qop = val;
 >     LOG(L_NOTICE,"NOTICE:uac:parse_authenticate_body: no qop "
 >                  "support for the moment :-( -> ignoring\n");
 >     break;

But unfortunately I discovered that it doesn't work - at least for me.
The following example did the job (at least for OpenSER 1.1):

 >   case QOP_STATE:
 >     break;

I didn't test this one with 1.2 - but I'm pretty sure that it would
work. (As fas as I can remember I gave the first variant a quick try
some time ago in 1.1 - and it failed there too.

No core file, but at least some (cleaned up) syslog output:
