[SOLVED] pfBlockerNG alerts don't display

[fsoyer]

Hi there,
first, as newbee in this forum, let me say thank you and bravo for PFSense.
New here but not with Pfsense, I use it since about 2 years. I post here for a strange behavior with pfBlockerNG. In fact, I'm not sure that it's really this package the problem, but it occurs with it.
On a 2.2.1 amd64 PFSense, installed as cluster, I've yesterday installed pfBlockerNG. No problem to make it work, but when I wanted to see the alerts, the GUI display a blank page, then on home page warned for a crash : PHP fatal error caused by memory_limit in /etc/inc/util.inc.
I increased the memory with the ini_set command, but it always complained about memory, even with 512M RAM ! So I started to debug.
I found that the problem came from this function in util.inc : function subnetv4_expand($subnet)
and especially this loop :
        for ($i = 0; $i < $size; $i += 1) {
              $result[] = long2ip($net | $i);
        }

Strangelly, it fills memory, but (I'm not developper stop me if I'm wrong) the $result variable should be overwritted at each loop and return only the last result, isn't it ?
So I simply commented the loop and replace it just by :
  $result[] = long2ip($net);

and all begun to work !

The IPs are CARP VIP, one on LAN at 10.0.0.254/8, and others WAN on /32 public adresses. 1G RAM actually used at 40%.
I've also installed the package on another PFsense, same version, a cluster master too, with CARP VIPs, 1G RAM, but can't reproduced the problem. I don't see what is different on this PFSense.

So finally my question :)
I'm pretty sure that this util.inc isn't part of the package pfBockerNG. During my tests, I found that it is used by others parts of PFSense. And I don't understand what the hell this loop is doing ??? And, if the modification can break something else ?

Thanks !

Hi fsoyer,

I have an update the Alerts tab that doesn't call this function and instead uses the following function below as its more practical then trying to expand such a large cidr. I have just been busy working on v2.0 of pfBlockerNG with DNSBL that I haven't pushed some of these changes into the release. Hope to get a pull request submitted soon.

ip_in_subnet($subnet, $line)

Fine ! Hope that this update will be release soon, but for the moment it seems to works like that. Happy to hear about DNSBL too ! Thanks.
Just fo my understanding, if you have time to describe what this loop should do ?

[fsoyer]

Well. The patch you sent to me works fine.
Thank a lot.
