Suricata blocking networks in Pass List

[rearden27]

@bmeeks Thank you for your quick reply. Tell me if there are logs which may be helpful or suggested work arounds.

No, unfortunately there are no logs that will help as nothing to do with the Radix Tree is logged anywhere. And I don't know of a workaround because I honestly have never been able to find the problem. Not doubting folks have the issue, because it has been reported by several users. But it is fairly rare, and seems somewhat random.

If I could reliably duplicate the issue, it would be a piece of cake to debug and fix. But every single time I've tested in my virtual machine test environment, I can't make the problem occur. Not once have I made it happen for me. One user even sent me his entire Pass List, and I copied it verbatim into two different virtual machines and tested. Could not get his problem to replicate for me. Still not doubting he has the issue, because I could see his blocks in his screen caps like I see yours, but I just could not duplicate it so I could debug and troubleshoot it.

@rearden27 If you restart Suricata on LAN does it still recur? Do the Home and External lists look OK?

[bmeeks]

I suppose it's within the realm of possibility that the problem is a threading concurrent access one. Although the blocking plugin code, during normal runtime, will only ever read from the Radix Table. It adds addresses to the table during the initial startup of Suricata, but not afterwards.

That could explain why the bug appears somewhat random. This is just an hypothesis, though.

I had the same issue some time ago. I rebooted the FW and havent seen the problem since.

@bmeeks, something like https://redmine.pfsense.org/issues/12322 ?..

No, this problem is not an error in the YAML config. The Pass List is a separate text file written to the interface subdirectory under /usr/local/etc/suricata/. The text file can be opened and read in any text editor. The custom blocking module within the binary opens and reads in the contents of the text file during startup initialization of Suricata.

In the past, when other users have checked the text file, it contained the proper information. So I suspect the OP will find that his file, too, contains the proper networks. Something happens randomly, I suspect, in the code that is testing IP addresses pulled from the alerts against the addresses and/or subnets stored in the Radix Tree table, such that it fails to find a match when it should. That would lead to erroneous blocking of Pass List IP addresses.

@rearden27 What hardware are you using?

[rearden27]

I have rebooted several times. This has been happening for a while. I have just gotten around to spending some time on it.

I am running on a Dell Optiplex 3020 minipc with a Intel(R) Core(TM) i5-4590T CPU @ 2.00GHz and 16GB. It has one built in nic (WAN interface) and I have two usb nics. One is a Pluggable 2.5G (LAN interface) and the other is an old 100mbit (for the OPT interface). All are Realtek. I am using the updated FreeBSD Realtek driver. The only option for expansion is a m.2 slot, so I have been unable to find an option to use it as a nic which will work in the system.

The system is pretty simple, no VLANs, no virtualization. Suricata is on the LAN. The only installed extra packages are PFblockerNG-devel and Status Traffic Totals. The install is only about a month old.

The HOME LIST contains 192.168.5.0/24 and the External Net has !192.168.5.0/24 they are all Default.

[SteveITS]

@rearden27 Brainstorming, can you see in the system logs if the USB LAN is coming up after Suricata starts?

What if you create your own pass list for Pass List or maybe Home Net, check all the boxes, and ensure 192.168.5.0/24 is in the alias? I wonder if that might fool it into adding that network even if it's not seen properly at startup.

Also note I suggested restarting Suricata, not pfSense, since all interfaces are (now) up.

[bmeeks]

If you want to verify the subnet is actually present in the loaded Pass List, just do this:

1. Go to the DIAGNOSTICS > EDIT FILE menu choice in pfSense.

2. Browse to the following location: /usr/local/etc/suricata/suricata_xxxxx/ where xxxxx is going to be a string composed of the physical interface name and a random UUID number.

3. In that subdirectory, click on the passlist file to view its contents.

Verify the IP addresses and subnets shown. Everything is plaintext. I'm betting the 192.168.5.0/24 subnet will be properly showing. If it's not (which I doubt), then you've found the problem. But I suspect it will be showing. In that case the problem is back to a random issue within the binary code of Suricata and has nothing at all to do with the PHP GUI code.

random issue within the binary code of Suricata

Has anyone reported this with Snort? If not that could be an option for OP.

(we've not seen this for any of our clients' instances, with either)

[rearden27]

I have created a custom Passlist and verified that it contains 192.168.5.0/24

I have restarted Suricata.

I will wait and see if blocks any LAN addreses.

Here is the OS boot log. I did have to modify the script to get the usb to automatically find the usb.
<earlyshellcmd>usbconfig -d 0.5 set_config 1</earlyshellcmd>
and you can see the:
ugen0.5: <Realtek USB 10/100/1G/2.5G LAN> at usbus0
in the log.

On the dashboard Interfaces there is an oddity, in that it does not report 1000baseT <full-duplex>. It is just blank for the LAN interface.

random issue within the binary code of Suricata

Has anyone reported this with Snort? If not that could be an option for OP.

(we've not seen this for any of our clients' instances, with either)

I don't really recall it being reported much at all with Snort. I think the few times something like that has been reported with Snort it turned out to be a user error (most often either failing to assign a custom list on the INTERFACE SETTINGS tab, or failing to restart Snort after changing the assignment).

The internals of the custom blocking plugin work the same way in both packages. The difference is in the native binary calls the plugin makes to check an IP pulled from an alert against those stored in a pass list.

In Snort, the custom plugin keeps its own linked list, and it calls a Snort utility function called sfip_contains() to see if a pass list entry covers the IP pulled from the alert.

In Suricata, the custom plugin uses the built-in Radix Tree functionality packaged with the Suricata binary. My suspicion is an obscure bug in that Radix Tree code. But it could also be something my custom blocking plugin is doing subtly wrong when using that built-in API. It gets back to the fact if I could reliably reproduce the bug, I could fix it.

Realtek NICs are problematic at times in FreeBSD, and a USB Realtek would likely be doubly so. In a sense, you are lucky it works at all.

However, the type of NIC is not the issue here at all. It is something peculiar within the Suricata binary code that seems to get triggered in rare circumstances. So far, I've been unsuccessful in identifying how to reliably trigger the bug. And therefore, fixing it has been an impossible task.

[rearden27]

@bmeeks Thank you for looking at this. I appreciate it.
The Realtek's have been squirrelly. But I have not been able to find a solution to my lack of expansion ports and no intel usb3 nics.
