      After the last error i decided to uninstall everything and reconfigure from scratch
      maybe some configuration didn't migrate correctly
      now i'm unable to reproduce the error at start

        This has been the experience of a few other users as well all the way back to the original release of 7.x Suricata in pfSense. That's what makes this such a maddeningly difficult thing to debug 🤔.

          I am continuing to look into this issue. Just sent a new batch of emails to the Suricata development team with questions about some recent changes in this area of the Suricata binary's code.

          Still would be nice if I could reliably reproduce this in my test machines with a debug image running.

            Attention Users hitting the Suricata Hyperscan problem (or other mysterious Suricata stoppages):

            To help in pinning down what this problem is, please collect the following information for me when you experience the crash and include it in your post or feedback.

            1. Are you seeing a Signal 11 or Signal 10 error fault logged in the pfSense system log (under STATUS > SYSTEM LOGS) around the time Suricata crashed? If so, include those log entries in your report.

            2. Before attempting to restart Suricata after finding it stopped or crashed, examine the suricata.log for the interface under the LOGS VIEW tab in the Suricata GUI. Examine that log for any errors mentioning "hyperscan". Include those in your report.

            I am trying to determine if a Signal 11 or Signal 10 happens each time Suricata crashes, or if Suricata is sometimes just stopping on its own when it encounters an internal hyperscan error.

            Please provide the information requested above when posting about this issue. It is not helpful at all to simply create a reply saying "I'm having this problem, too" with no additional helpful information.

            And at this time there is no indication at all the hyperscan crash issue is related to the Legacy Blocking Mode bug shared with Snort. That bug has, I'm fairly confident, been fixed. I think the issue in this thread is something different.

              @kiokoman Do have a backup config 1) from before upgrading, 2) that wasn’t working and 3) after rebuilding? Might be interesting to compare the Suricata section to see if anything is different across those.

              (I usually save one just before upgrading and immediately after)

              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.

                i have the backup history,
                the only difference after reconfiguration was

                old not working config:

                <stream_bypass>off</stream_bypass>
                <stream_drop_invalid>off</stream_drop_invalid>

                vs
                new config
                <stream_bypass>no</stream_bypass>
                <stream_drop_invalid>no</stream_drop_invalid>

                everything else is the same but i don't have the old generated suricata.yaml

                anyway i have a new problem now, before it was not even starting, now i have this after some hours, and only on one interface (i have suricata running on wan and lan, wan(vmx1) is still running ok)

                  Those small differences in Boolean values from the config.xml file would not be a factor here. Something is most likely wrong within the Suricata binary itself, but I don't know where nor do I know that is absolutely true.

                  I've had a virtual machine running for 36 hours- with every single ET Open rule enabled and the Snort IPS Connectivity Policy enabled- and have not seen a crash yet. So, this is a strange problem. To positively identify it is going to require being able to reproduce it easily. Then a debugging version of Suricata can be executed and the precise failure point identified. But so far I cannot reproduce the problem. And even in @kiokoman's case, the problem disappeared for a time and then recurred later under different circumstances (running versus starting up).

                  There were some upstream changes in the HyperScan portions of Suricata code starting with version 7.0.1. Those were to work around some problems introduced by a behavior change upstream made by Intel in the HyperScan library itself. I've been communicating with the Suricata developer team, and they are pretty confident the fixes they made are sufficient. Nobody on Linux seems to be having a problem. The vast majority of Suricata users are on Linux derivatives. Very few users are on FreeBSD- mostly just the pfSense and OPNsense users. I'm not seeing this problem reported on the OPNsense forum, but they are still running the 6.0.x branch of Suricata and not the new 7.x branch.

                    If you are willing, please try the following workarounds for me.

                    Perhaps try just the first one initially, and if you still have the crash, then add on the second one. This command will disable ASLR (address space layout randomization) for the Suricata binary.

                    Execute this from a shell prompt after first stopping all Suricata instances.

                    1. This will disable ASLR for the Suricata library:
                    # elfctl -e +noaslr /usr/local/bin/suricata

                    Each time you make a change above, stop the Suricata processes, make the change, then restart the processes. The change above is not dynamic. It only sets the "turned on/turned off" flag when loading the target binary.

                    This is a shot-in-the-dark based on my theory that perhaps ASLR is tripping up either the HyperScan library or Suricata. I remember unbound had an issue with ASLR a few versions back, and the temp workaround until upstream fixed the underlying problem in the code was to disable ASLR for the unbound binary.

                    To reset this back to the default, execute the same command but with a minus ("-") instead of plus ("+"). An example is below:

                    # elfctl -e -noaslr /usr/local/bin/suricata

                    Please report back if you try this and let me know if it helps.

                      @bmeeks,

                      Symptom: WAN Suricata instance works just fine, but the PC (one of several LAN side interfaces) interface instance dumps core immediately after starting with Signal 11.

                      Nov 25 14:43:06 	kernel 		pid 36387 (suricata), jid 0, uid 0: exited on signal 11 (core dumped)

                      The Suricata log for the PC interface does not contain any reference to hyperscan.

                      I tried the ASLR changes that you suggested. The first one didn't appear to work.

                      elfctl  -e +noaslr /usr/local/lib/libhs.so.5.4.0
elfctl: NT_FREEBSD_FEATURE_CTL note not found
elfctl: NT_FREEBSD_FEATURE_CTL note not found

                      The second one, for the Suricata binary did work. Now when I start Suricata both instances start and so far they appear to stay running. However, if I shutdown Suricata I see the Signal 10 and core dump.

                      Nov 25 15:26:11 	kernel 		pid 22945 (suricata), jid 0, uid 0: exited on signal 10 (core dumped)

                        @bmeeks,

                        It appears I spoke too soon. Now my WAN interface instance of Suricata is dumping core and the PC one is staying up. The WAN interface suricata.log file does include the Hyperscan log entry that you're chasing. As you can see from the logs, the instance ran for about 18 minutes before dumping core and reporting the Hyperscan error.

                          Oops, looks like the library does not offer that option. I'll update my previous post to remove attempting to disable ASLR in the library. But it does work for Suricata (at least disabling ASLR, that is).

                            Hello,

                            I'm having the same problem.

                            I have 6 interfaces set up with Suricata. and only 2 of them are stopped randomly.
                            One using IX0 on WAN
                            And the other one using VLAN on IX1
                            device = '82599ES 10-Gigabit SFI/SFP+ Network Connection'
                            Using IPS Mode - Legacy Mode

                            I deleted one of the monitored interfaces in Suricata that was having the issue, duplicated a working one. And got the same error on the new (same as before) interface. Also tried to disable some of the working ones but nothing changed.

                            Suricata log

                              @jowe78 Have Suricata in IPS mode on the WAN interface. Had a crash once a day with hyperscan mode. Yesterday I switched to AK-CS mode and it crashed in half a day running. There is no error in logs.
                              Now I'm switching to AC-BS mode and keep you updated.

                                  Hello,

                                  I'm having the same problem.

                                  I have 6 interfaces set up with Suricata. and only 2 of them are stopped randomly.
                                  One using IX0 on WAN
                                  And the other one using VLAN on IX1
                                  device = '82599ES 10-Gigabit SFI/SFP+ Network Connection'
                                  Using IPS Mode - Legacy Mode

                                  I deleted one of the monitored interfaces in Suricata that was having the issue, duplicated a working one. And got the same error on the new (same as before) interface. Also tried to disable some of the working ones but nothing changed.

                                  Suricata log
                                  [607907 - W#02] 2023-11-27 08:35:42 Error: spm-hs: Hyperscan returned fatal error -1.

                                  System log.
                                  Nov 27 08:35:42 kernel ix0: promiscuous mode disabled

                                  That is really puzzling. It is very hard to pin down what the root cause of this might be 🤔. Are the rules different on the interfaces with no issue compared to the interfaces that are crashing?

                                    elfctl did not help for me

                                    Hmm...I was sort of afraid that might be the result. Another user tried it and it seemed to work very briefly, but then a crash. The random nature of this bug is frustrating. It's happening with different physical interfaces, it happens immediately for some users (they can't even start an interface), but for other users it happens at random points during a long runtime.

                                    how about vectorscan? there is plan for it?

                                    Vectorscan is somethig Suricata upstream would have to incorporate into the binary. All we do on the pfSense side is take the upstream source code for the binary and add the custom blocking plugin for Legacy Blocking Mode.

                                    I'm also unsure at this point what the support level is in Vectorscan for Intel devices. It was first developed to bring hyperscan-like technology to ARM and other non-Intel CPUs.

                                      @jowe78 Have Suricata in IPS mode on the WAN interface. Had a crash once a day with hyperscan mode. Yesterday I switched to AK-CS mode and it crashed in half a day running. There is no error in logs.
                                      Now I'm switching to AC-BS mode and keep you updated.

                                      There is no error in any log? Always check BOTH the pfSense system log under STATUS > SYSTEM LOGS and the suricata.log under the LOGS VIEW tab in the Suricata GUI.

                                      Different things are going to be logged in each. For example, if Suricata hard crashes, it can't log anything into suricata.log about the crash because the binary died suddenly. But the pfSense operating system will see the binary crash and log information about it in the pfSense system log.

                                        @bmeeks I wrote it explicitly because it was unusual: in system.log the last entry about suricata was a detection log. Nothing about crash.
                                        Mine still running with AC-BS Matcher Algorithm. I even did a manual update, successful.

                                          That is really puzzling. It is very hard to pin down what the root cause of this might be 🤔. Are the rules different on the interfaces with no issue compared to the interfaces that are crashing?

                                          I have all rulesets applied to all interfaces, but not all rules enabled. So there are exceptions, then some rules are disabled to ensure functionality. So there are differences
                                          between the interfaces.

                                          I will start fresh on one of the interfaces to see how it works.

                                            @bmeeks in my case, no (configured) variance between interfaces.

                                            I recently removed Suricata, including all configuration, caches, logs, etc., and installed fresh. Created the first interface, then copied it to create the second. First interface seems to be stable, but the second will die fairly shortly after start, due to the aforementioned hyper scan problem.
