Subject:  bug in allow_source_address?

I¹m using allow_source_address in my Kamailio config and have been for
months/years.  I¹ve had no issues with it until today.

The issue is that allow_source_address("1²) returns ³1" (for
$si=123.17.29.201 and $sp=5060) even though we don¹t have this IP address in
the Œaddress¹ table for group 1.  We have defined this IP address for group
2 but not group 1.

select * from address order by mask;

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

| id | grp | ip_addr       | mask | port | tag      |

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

| 20 |   1 | 123.17.0.0    |   23 | 5061 | Testing  |

| 22 |   1 | 123.17.0.0    |   23 | 5062 | Testing  |

| 23 |   1 | 123.17.0.0    |   23 | 5063 | Testing  |

| 24 |   1 | 123.17.0.0    |   23 | 5064 | Testing  |

|  1 |   1 | 123.17.0.0    |   23 | 5060 |          |

|  4 |   1 | 20.5.176.0    |   24 | 5060 |          |

| 21 |   1 | 123.17.1.235  |   32 | 5060 | Override |

| 46 |   2 | 123.17.29.201 |   32 | 5060 | customer |

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


Can anyone explain this?  I¹m wondering if there¹s a bug in how
allow_source_address does its net mask calculations.
