pfSense Plus and SG-3100

stephenw10

The PHP issue, which is what you will be hitting with pfBlocker and Suricata, seems to be very load dependent.
I have both those running here on SG-3100s in 21.02p1 without any problems. The throughput on the those is not huge and I don't have a large number of lists loaded though.

Hello Steve, if you install pfblockerng, run the wizard, and reboot, you get:

done.
Configuring firewall.
pflog0: promiscuous mode enabled
pid 401 (php-cgi), jid 0, uid 0: exited on signal 11 (core dumped)
Segmentation fault (core dumped)
Starting CRON... done.
 Starting package IPsec Profile Wizard...done.
 Starting package AWS VPC Wizard...done.
 Starting package acme...done.

Nothing works, to recover access, you need, through the console, select the option 11, disable pfblockerng and reboot again.

Hmm, interesting. I aleady had it installed before the upgrade. And the wizard is only in the development version which I'm not running on that firewall.
Are you able to install the non-dev version?

Steve

Yes, I can do it right now to confirm, but, as I have been reading everything about this lately, I already found reports from users with the same problem using the non-dev version.

Installed pfblockerng non-dev, enabled it, I'll wait for the update, then reboot, updates soon.

stephenw10

It certainly can hit that same issue in the non-dev version if you have a lot of lists loaded triggering the issue when php tries to parse them.

Same lists that I used to have in 2.4.5p1, are failing with 21.02, and 21.02p1.
I usually just run pfblockerng defaults settings to test, and it fails to boot..

mcury

non-dev version, default settings.

stephenw10

Hmm, what are you actually enabling there? The non-dev version doesn't have a wizard to set defaults. I may have disabled some things on my install. I don't use the auto-added firewall rules.

Default settings, just install it, wait for the update, or force it, then reboot..

stephenw10

By default it is not enabled at all so I assume you enable it?

There are no lists enabled by default either so I assume you added some? Or it pulled in values you already had?

Enabled pfblockerng, wait for the update.
There are lists enabled by default, didn't add anything.

Just install, enabled it, update it, and reboot, and the bug happens.
Same bug that was happening with 21.02, and this never happened with 2.4.5p1.

stephenw10

There are no lists enabled by default so it must be using lists you have in your config already. What lists do you enabled there?

ON the box I have running it without issues I have it installed mostly for ad-blocking. This is what updating looks like:

@stephenw10 Tick the option to enable pfblockerng, and update, there are lists by default, you don't need a wizard.
This will create an alias for a firewall rule in LAN with malicious IPs and etc, and that causes the problem during the boot.

stephenw10

Yes, I did that on another test box that has never had pfBlocker installed and there are no default lists.

So if you are seeing lists it's because they already exist on your config and pfBlocker is using them.

What lists do you see?

If that is the case, the same lists that pfblockerng 3.0.0_15 has, because it was the last pfblockerng version installed.

mcury

@teamits found another way to trigger it.. not sure if it's the same problem, but try:

ssh to pfsense and type:
gpioctl 2 0

stephenw10

@mcury said in pfSense Plus and SG-3100:

gpioctl 2 0

Hmm, interesting. Not the same issue though, php is not involved there:

Mar 14 13:52:52 	kernel 		pid 32606 (gpioctl), jid 0, uid 0: exited on signal 11 (core dumped)

Likely that's because the first GPIO device cannot be set like that. You can set a PWM duty there. It should not segfault though.

Steve

mcury

Any news about this issue?

#11466 latest update on 03/11/21, nobody is assigned to that task..

Searched for this PHP bug in https://bugs.php.net/ and couldn't find anything about this PHP interpreter error for ARM 32 bits and/or Freebsd..

stephenw10

Nothing specific yet I'm afraid. We are looking at it though just no-one has been assigned in Redmine. Details will be on the bug report there as we confirm them.
We have a separate internal report we use until we have something useful to add publicly.
