Freeradius 3.0.8 - expansion and unlang - concatenation of AVPs

[Aleš Rygl]

Hello all, 

With freeradius 3.0.8 and MariaDB 10.0.19 I am
struggling with concatenation of AVP in case of their multiple
occurrence: According to http://freeradius.org/radiusd/man/unlang.html
the expansion below should produce a string separated by n


_%{Attribute-Name[*]}_ 

_ All values of Attribute-Name, concatenated
together with n as the separator. _ 

Basicaly it works. But what I can
see is than instead of a newline there is "=2C" sequence inserted to the
acct table. It regards Dynamic-QoS-Param AVP below: 

query = "
 INSERT
INTO ${....acct_table1} 
 (${...column_list}) 
 VALUES 

('%{Acct-Session-Id}', '%{Acct-Unique-Session-Id}', '%{SQL-User-Name}',

 '%{NAS-IP-Address}', '%{NAS-Port-Id}',
FROM_UNIXTIME(%{integer:Event-Timestamp}), 

FROM_UNIXTIME(%{integer:Event-Timestamp}), NULL, NULL, 

'%{Connect-Info}', '%{Acct-Input-Octets}', '%{Acct-Output-Octets}', 

'%{Acct-Input-Packets}', '%{Acct-Output-Packets}',
'%{Acct-Input-Gigawords}', 
 '%{Acct-Output-Gigawords}',
'%{Called-Station-Id}', '%{Calling-Station-Id}', 
 '%{Callback-Number}',
'%{Framed-IP-Address}', '%{Acct-Delay-Time}', 
 '0',
'%{Acct-Status-Type}', '%{Acct-Terminate-Cause}', 
 '%{Mac-Addr}',
'%{NAS-Identifier}', '%{Dynamic-QoS-Param[*]}')" 

And when sql trace
tunrned on, I can see that it is being inserted in this way by
freeradius: 

INSERT INTO radacct_adsl (......., 'pwfq-circuit-rate-max
23716 parent=2Cpolice-circuit-rate rate-absolute 2240 parent'); 

Client
charset and DB charset is utf8. "2c" represents comma in utf8. 

What am
I doing wrong?
