I'm glad it works.

I definitely think this must be pushed as bug fix (as it poses serious limitations) , but we need to be very careful to backward compatibility (which may be affected)...do you see any way nicely deal with this ?

Hi John,

There was a small bug - please test this new attached patch (remove the prev
one).

Hi Bogdan,

  From my initial testing, I think the inner while loop never terminates.
Luckily I added a trap using an integer counter with a limit of 40
iterations.
What is it in the call to rc_avpair_get() that allows it to cycle
through each instance with a matching name rather than just keep
getting the first instance?

Hi Bogdan,

If the variable is a var, at the moment you would only get the first
value.
After modification, you would only get the last value. I agree this
is changed behaviour, but one case does not seem to me to be any
worse than the other. The advantage that multiple values *can* be
returned in an AVP seems to me to outweigh the risk of changed
behaviour on the next release of OpenSIPS. For me, it would be a
great advantage to be able to retrieve multiple values where this is not
possible at the moment.
If you are able to send me the diff file (or simply a description)
for the changes, I would be happy to test it here.

Thanks for responding.

John

John,

We could do that (pushing back to OpenSIPS all values for that RADIUS
AVP), but it may be dangerous if you use on the OpenSIPS side a
variable that does not support multiple values - actually the AVPs
are the
only one doing that.
Imagine the RADIUS reply returns multiple instances on an RADIUS AVP.
And you use a $var() variable to get the value - each value will be
pushed to that $var(), but as it can hold only one value, it will
keep being overwritten -> only last value will be actually available.
If this behavior is not a problem, we can fix the code and iterate
through the entire list of RADIUS AVP and get all instances.

Bogdan,

I was hoping to get all the values returned in 1 avp, the avp
defined for Cisco-AVPairs in set2. This takes advantage of the
ability of OpenSIPS avps to hold multiple indexed values and also
means minimal changes to the documentation of the aaa_radius module.
If you add a numeric index in the set definition, you must know
which position the required attribute is in and it is even possible
the server may return
them in a different order.
Also, if you want to retrieve 10 values this makes the set2
definition very big and clumsy. Adding an index in the set
definition would only be a good solution if the index was a string
identifying the Attribute name within Cisco-AVPairs.

I would be very happy to test if you can show me what changes need
to be made in the sources. I would have tried it already, but wasn't
sure how to add multiple values to the avp.

John,

I understand the issue and agree over the need of a solution. Two
possible
approaches:
         - return all the values for that radius AVP
         - include an index in the set definition - to say which
instance of the radius AVP you are looking for

Hi Bogdan,

Yes absolutely certain. I used Wireshark to check.

I did make a little progress with this problem after finding some
info on the Internet.
The name that has to be used in set2 is "Cisco-AVPair". This allows
me to retrieve just one VSA value.
The *real* problem is that you cannot retrieve values 2, 3, 4, etc.
This is because multiple instances are returned using the same VSA.
They are all returned by the server in the attribute called
h323-ivr-in. I even found the code in the sources that retrieves them.
It loops through every instance in
set2 and looks for 1 matching value. So even if you add "Cisco-AVPair"
several times into set2 all you get is the first matching value
many
times.

Hi John,

It may be a stupid question, but are you sure the AVP does exist in
the RADIUS reply ?

Hi,

With help from this forum, I have just got radius_send_auth working.
I needed some extra dictionaries including dictionary.cisco In
that dictionary, there are vendor specific attributes like this:
ATTRIBUTE       h323-ivr-in                     100     string
Cisco
ATTRIBUTE       h323-credit-amount              101     string
Cisco

My Radius server returns some data using these VSA's. In
particular, it returns many values using the same VSA -
h323-ivr-in

I am having trouble recovering the returned values using set2 of
radius_send_auth Can anyone advise me how I should define set2 to
get at these returned values? I have tried the following with no
success:
modparam("aaa_radius", "sets", "set2 =
(h323-return-code=$avp(retcode),
h323-ivr-in=$avp(authretvals))")

After the function is called, there are no values in
$avp(authretvals)

Thanks.
