Segmentation fault after [peap] Using saved attributes from theoriginal Access-Accept

[chenjiang]

   Hi! Experts

   I want to achieve user traffic volume limit per month, but found there
   is a limit for user traffic to exceed 4Gbytes.

   Below is my DB structure, you could see the
   "Max-Monthly-Trafficâ groupcheck attribute is 10Gbytes and it type
   is âvarchar", but it seems system deal it like a âinteger" type, so it
   cannot exceed 4Gbytes.

   mysql> desc radgroupcheck;

   +-----------+------------------+------+-----+---------+----------------
   +

   | Field     | Type             | Null | Key | Default | Extra
   |

   +-----------+------------------+------+-----+---------+----------------
   +

   | id        | int(11) unsigned | NO   | PRI | NULL    | auto_increment
   |

   | groupname | varchar(64)      | NO   | MUL |         |
   |

   | attribute | varchar(64)      | NO   |     |         |
   |

   | op        | char(2)          | NO   |     | ==      |
   |

   | value     | varchar(253)     | NO   |     |         |
   |

   +-----------+------------------+------+-----+---------+----------------
   +

   5 rows in set (0.00 sec)

   mysql> select * from radgroupcheck;

   +----+--------------------+-----------------------+----+------------+

   | id | groupname          | attribute             | op | value      |

   +----+--------------------+-----------------------+----+------------+

   |  1 | disabled           | Auth-Type             | := | Reject     |

   | 25 | group2        | Max-Monthly-Traffic   | := | 10737418240|

   | 33 | microshield        | Acct-Interim-Interval | := | 300        |

   +----+--------------------+-----------------------+----+------------+

   3 rows in set (0.00 sec)

   In FreeRADIUS debug mode, we could see that the rlm_sqlcounter
   âcheck_itemâ is always warpped in 4294967296 just like below:

   [monthlytrafficcounter]

   expand: %{sql:SELECT SUM(acctinputoctets+acctoutputoctets) FROM radacct

   WHERE username='lichan' AND UNIX_TIMESTAMP(acctstarttime) >
   '1425139200'} -> 7250810110

   rlm_sqlcounter: (Check item - counter) is less than zero

   rlm_sqlcounter: Rejected user lichan, check_item=2147483648,
   counter=3955842814

   ++[monthlytrafficcounter] returns reject

   And this always leads users been rejected in authentication procedure.

   Do you have any experience in this and could shed some light? Thanks
   for your great help!
