      @bmeeks I noticed this in another thread:

      @jimp said in Major DNS Bug 23.01 with Quad9 on SSL:

      While we are likely to include the patch from that EN in future builds it isn't relevant to Unbound.

      They only use those sanitizers for debug/test builds and not for normal/production builds.

      Pre-2.7.2/23.09: Only install packages for your version, or risk breaking it. Select your branch in System/Update/Update Settings.
      When upgrading, allow 10-15 minutes to restart, or more depending on packages and device speed.

        Hello fellow Netgate community members,

        I recently learned that Snort and Suricata's maintainer does all this work you what you see here unpaid. I opened a ticket to have a Wikipedia type donate to maintainer button on all 3rd party packages. I personally want to send some money to maintainers. If you also feel the same way please respond to this Redmine.

        Happy Holidays.

          Hello, I also have the same problem, I tried all the recommendations proposed on this topic, but without success.
          However, I noticed that the problem only occurs on the network interfaces with higher traffic and not on the interfaces with low traffic.

          I have a Pfsense 23.09 installed on a Hyper-V machine, so no VLANS.
          There are 6 network cards (without VLANS).

          Initially Suricata was active only on the WAN and it deactivates after an interval between 1 hour and 7-8 hours.
          For testing I enabled Suricata on all interfaces. And I noticed that now it stops only on the WAN interface and the LAN interface on which the network traffic is higher. Suricata never stops on the interfaces where the traffic is very low.

            Hi all.
            It seems I get the same bugger of an error and Suricata stopes running on (yes you guessed it) one interface.
            I've read through most of the post here without finding a solution.
            Is there a solution? Or?

            So what is next? A patch? Or an Update?

            I'm on pFSense 2.7.1 and Suricata 7.0.2_1.

            And yes, is there a way to turn off e Hyperscan system so that Suricata runs without it?

            Paal B.

              use AC-BS instead of Auto

                Currently no patch is available because the cause of the failure has yet to be determined. I cannot reproduce it in my limited test environment. At least I have not yet encountered it. It is a seemingly random sort of bug impacting some users and not others. Very difficult to troubleshoot a failure that you cannot reliably reproduce, but I'm still trying.

                You can disable the use of the Hyperscan library by going to the INTERFACE SETTINGS page for an interface and scrolling down to the Pattern Matcher Algorithm parameter and choosing something other than Auto or Hyperscan. Save the change and restart Suricata on the interface so that the underlying binary sees the new parameter choice.

                  For me, the problem always manifests itself only on the network interfaces on which there is some traffic. The problem does not appear on network interfaces with low traffic.
                  The problem appears after an interval between 1-8 hours, probably the higher the traffic, the faster the problem appears.

                    Hmm...that does make some sense. I am testing with very low traffic in a limited VMware Workstation virtual machine setup. Perhaps hammering a test machine with iperf3 traffic might trigger the bug ???

                        idk if iperf3 can generate enough alert to trigger the bug maybe it's more like how many alert there are more than how mutch data is in the wire

                          @bmeeks I was trying to use the AC-KS pattern matcher as an alternative to hyperscan, but they must be related in some manner. This is the log I receive after just a few minutes running AC-KS. Also, I'm getting the hyperscan errors on my WAN interface, which remains busy, but also on this interface that has little traffic and does not alert all that often, so it isn't just interfaces that are more active on my network.

                          Here is the last few lines in suricata.log for the failed interface running with AC-KS:

                          I'll try and run this interface on auto (hyperscan) and catpure the core dump to post the debug details here. Again, this is on my smaller interface that has been failing with suricata. If that doesn't prove as beneficial, I'll work on getting my wan interface to produce the core dump with hyperscan to get you that debug info.

                            I'll try and run this interface on auto (hyperscan) and catpure the core dump to post the debug details here. Again, this is on my smaller interface that has been failing with suricata. If that doesn't prove as beneficial, I'll work on getting my wan interface to produce the core dump with hyperscan to get you that debug info.

                            Thank you for this info. Weird that it seems to be crashing in a section of code where Suricata is releasing memory and cleaning up after reading the configuration from the suricata.yaml file. Those calls to ConfNodeFree() and ConfNodeInit() are made when finishing and cleaning up from reading the YAML conf file parameters.

                            Let's see if another crash happens in the same area of code. One thing I noticed before (but that might have been with the Kill States bug and not Hyperscan) was the crash happened in seemingly random and unrelated places.

                            Please continue posting the relevant sections of any future core dumps' backtrace as you did here.

                                So, it seems to be crashing in the same place. Struggling to tie this behavior back to Hyperscan and the custom Legacy Blocking Module, but perhaps there is some link there I'm missing. I'll dig around for a bit.

                                  @bmeeks I can't help you with that side, but I know it keeps referencing hyperscan in the logs with the fatal error and it only occurs when I am using auto, which defaults to hyperscan, but also when I use AC-KS for the pattern matcher. It doesn't happen with AC only (I haven't tried AC-BS or specifically selecting hyperscan).

                                  [102876 - W#02] 2023-12-07 11:27:44 Error: spm-hs: Hyperscan returned fatal error -1.

                                    The strange thing.
                                    Now after I set it to AC-BS it's been running for over 2 hours without failing.

                                    So seems to be up now.
                                    But does it work as it should?
                                    I checked Alert and last entry there was for like 4 minute's ago.

                                    Paal B.

                                      The Pattern Matcher Algorithm is not critical to whether detection works or not. It only matters in terms of speed versus memory consumption.

                                      All fhe pattern matcher does is execute a regular expression (regex) search against packet data looking for whatever pattern the rule specified. The different algorithms all accomplish the exact same thing. It's just that some use less memory, but may run slower. Others may be lightning fast, but that speed comes from very high RAM consumption.

                                      Hyperscan is a specialized regex library created by Intel to take advantage of certain complex math instruction op-codes present in their CPUs. Those specialized instructions that most Intel CPUs have allow for highly optimized regex searches. But because Hyperscan depends on instruction op-codes only present in Intel CPUs, the library does not work with ARM or any other non-Intel hardware.

                                      The Auto setting for the Pattern Matcher algorithm in Suricata will default to the Hyperscan library if it is present. Otherwise it will choose AC (Aho-Corasick). When the Suricata binary is compiled on the Netgate package builder, it automatically senses which type of CPU is targeted (Intel or something else), and then includes the Hyperscan library only for Intel CPU targets. This means if you have a Netgate firewall appliance with an ARM chip, the Hyperscan library is not even present on your system.

                                          @gfeiner Unfortunately, in my case at least, Suricata still dies after this upgrade.
