[ASTPPCOM-184] IP_MAP bad matching netmask

Thu, 1 Apr 2021 19:01:45 +0530

hi when we register a ip settings for example, 89.80.70.0/24 this not allow calls from 89.80.70.55 throws ([ASTPP] [Dialplan] Call authentication fail..!!).

this was our fast solution on astpp.functions.lua:

replace
~~~lua
local query = "SELECT "..TBL_IP_MAP..".*, (SELECT number FROM "..TBL_USERS.." where id=accountid AND status=0 AND deleted=0) AS account_code FROM "..TBL_IP_MAP.." WHERE SUBSTRING( ip, 1, CHAR_LENGTH( ip ) -3 ) = \"" .. params:getHeader('Hunt-Network-Addr').. "\" AND prefix IN (NULL,'') OR SUBSTRING( ip, 1, CHAR_LENGTH( ip ) -3 ) = \"" .. params:getHeader('Hunt-Network-Addr').. "\" AND \"" .. destination_number .. "\" RLIKE prefix ORDER BY LENGTH(prefix) DESC LIMIT 1"
~~~

with
~~~lua
local query = "SELECT "..TBL_IP_MAP..".*, (SELECT number FROM "..TBL_USERS.." where id=accountid AND status=0 AND deleted=0) AS account_code FROM "..TBL_IP_MAP.." WHERE (INET_ATON(\"" .. params:getHeader('Hunt-Network-Addr').. "\") & (0xFFFFFFFF & (-1 << 32 - SUBSTRING_INDEX(ip, '/',-1)))) = ((0xFFFFFFFF & (-1 << 32 - SUBSTRING_INDEX(ip, '/',-1))) & INET_ATON(SUBSTRING_INDEX(ip,'/',1))) OR SUBSTRING( ip, 1, CHAR_LENGTH( ip ) -3 ) = \"" .. params:getHeader('Hunt-Network-Addr').. "\" AND prefix IN (NULL,'') OR SUBSTRING( ip, 1, CHAR_LENGTH( ip ) -3 ) = \"" .. params:getHeader('Hunt-Network-Addr').. "\" AND \"" .. destination_number .. "\" RLIKE prefix ORDER BY LENGTH(prefix) DESC LIMIT 1"
~~~
