      1. Intel(R) Xeon(R) CPU E5-2667 and Intel(R) Core(TM) i5-4460 working, Intel(R) Celeron(R) N5105 is not.

      I’m running a N5105, and it’s running on mine with no problem. It was yesterday on 2.7.0 and overnight on 2.7.1

        The only difference is the machine with the Intel N5105 CPU also has Intel NICs (igc), the othere 2 have broadcoms (bge). I guess thats why they behave different.

        Do we see a pattern here?

          I can't see any scenario where the type of NIC hardware would have anything to do with Hyperscan. That technology is purely a thing within the CPU. It pre-compiles regex patterns for faster matching using special CPU opcodes that only Intel CPUs have. That's why Hyperscan does not work on non-Intel processors.

            Updating this thread with the latest as of the late afternoon of November 20, 2023.

            I've been mainly focusing efforts on getting the Signal 11 segfault error fixed in the custom blocking modules of both Suricata and Snort. That bug has been located, a fix identified, and Netgate is currently working through the logistics of getting that fix ready to deploy. Still working through a few kinks due to slight differences in some file versions in CE 2.7.1 and Plus 23.09. The fix builds in 2.7.1, but needs some tweaks still to build successfully for 23.09.

            Now on to the Hyperscan problem in Suricata. First off, I have unfortunately been unable to duplicate this in my test environment. All I have for testing are VMware Workstation virtual machines, so I can't duplicate everyone's unique hardware. Since I have thus far been unable to reproduce the failure some users are seeing, I can't know what the root cause might be much less verify any potential fix. There will be an updated Suricata package in the very near future to address the Signal 11 segfault discussed in the above paragraph. But that update will NOT contain any known fix for the Hyperscan problem. That's because I don't really know yet what that probem is 🙂. So, you will have to be patient for a while as I try to replicate the failure. It appears a viable workaround for now is to choose a Pattern Matcher algorithm other than AUTO or HS (HyperScan). AUTO will always choose HyperScan if that library is on the system, and HS forces the HyperScan choice. So, choose one of the other AC selections if you are hitting the HyperScan error until I can get the problem identified and resolved.

              This only works temporarily for me. Eventually Suricata will still crash. I've tried, AC, AC-KS, and I'm currently trying AC-BS. I'm also trying to see if "Signature Group Header MPM Context" being changed to full affects things. Changing "Detect-Engine Profile" from High to Medium definitely helps keep things running longer across the board. I'll change it down to Low if I keep seeing problems.

                  How much RAM is configured for the virtual machine? That error says Suricata ran out of memory.

                  One change made in the Suricata 7.x series was to substantially increase the memory sizes for the TCP stream_memcap and a few related parameters. That was done to match up with the new defaults from upstream and to prevent startup failures on multi-core machines. The more CPU cores you have, the more TCP stream_memcap memory you need to allocate.

                    I just found this topic after creating my own topic on the same issue (searches for some reason didn't find this result before I submitted).

                    I'm having the exact same issue with 2 interfaces with Suricata blocking on legacy mode. Both interfaces have the same message, one with blocks and one without blocks before they both halt with that error.

                    I'm running a 7100 with 23.09 and Suricata updated to 7.0.2, but it was occurring on the previous version of Suricata. I just checked and when I updated to Suricata 7.0.2, it still shows hyperscan 5.4.0. Looks like I'll just have to wait for an update to get pushed out for 5.4.2 to resolve this problem.

                    Are there any temporary config solutions to get these interfaces back online for monitoring? I'm guessing it is just specific rules that are triggering these to fail. I can go back through the suricata.log files for those 2 interfaces. There were some errors on specific rules, so if I disable each of those, might that do the trick for now? One of these 2 interfaces is my WAN, so a little more important than the others.

                    I'm going to give the AC pattern matcher on these 2 interfaces and see if it still crashes. Hopefully that will be a solution for me for the meantime.

                      @sgnoc said in Suricata process dying due to hyperscan problem:

                      There were some errors on specific rules, so if I disable each of those, might that do the trick for now?

                      Unlikely. If you are running any Snort VRT rules with Suricata, then several hundred of those rules (like around 700 or so last time I checked) are incompatible with Suricata and will fail to load. That's because Snort and Suricata are not 100% compatible with their rule syntax. When it encounters such rules, Suricata will log an error and ignore that rule.

                      @sgnoc said in Suricata process dying due to hyperscan problem:

                      Are there any temporary config solutions to get these interfaces back online for monitoring?

                      Changing the MPM pattern matcher alogorithm to something other than Auto or HS should work. If the HyperScan library is present for your system, then the Auto setting will always choose HyperScan. The HS setting forces the selection of HyperScan (if it is available, but remember HyperScan is an Intel creation and only runs on AMD64 CPUs, so not on ARM hardware).

                        @bmeeks I switched the 2 interfaces with the hyperscan fault to the AC pattern matcher last night, and it has run all night without failing. Everything is still running fine. I'll continue with the AC pattern matcher for now.

                        Are there any repercussions for using AC vs hyperscan? I'm guessing hyperscan is better for resources and performance, if it is the default chosen if available?

                        One other note, I know you mentioned the hyperscan 5.4.0 was listed by the upstream suricata developer team to be fine, but that is the version on my system, and I'm definitely getting the hyperscan error on 2 interfaces. I'm hopeful that their 5.4.2 version will be a fix, if they believe that 5.4.0 is not affected, but it is on my system with that version.

                        Thanks for all your hard work! If I can do anything to help from my end, I would be happy to try. I'm running the XG-7100 netgate hardware.

                          @bmeeks My WAN interface has halted again, but I don't see a log where it failed. These are the last few lines of suricata.log:

                          [101805 - Suricata-Main] 2023-11-23 18:32:40 Warning: detect-flowbits: flowbit 'file.pdf&file.ttf' is checked but not set. Checked in 28585 and 1 other sigs

[101805 - Suricata-Main] 2023-11-23 18:33:37 Notice: detect: rule reload complete

                          This triggered right after the Emerging Threats rules updated and the interface rules reloaded. The pid file is still listed in /var/run, which I guess makes sense since the process halted. There are no processes running for suricata on that interface when I check with "ps aux".

                          I was able to find this in the system logs:

                          What troubleshooting options do I have? Is this still related to the same problem, or is this a separate problem from the hyperscan issue that I need to switch to my own topic?

                              Signal 10 is a bus error normally associated with ARM-based hardware. What kind of machine are you running Suricata on? The Signal 10 error is more commonly associated with a non-aligned memory access, and that really can't happen on anything but ARM hardware these days.

                                @bmeeks I'm using a netgate xg-7100-u, which has an Intel x64 processor, and I have 24 GB of ram installed. It's only the one interface on suricata that has had that error, so I wouldn't think failing memory or other services should be having issues, I would think?

                                  By my calculations using the log timestamps, Suricata finished the rules update and ran for 41 minutes before crashing, so "right after the rules update" is not entirely correct.

                                  2023-11-23 19:14:37.481228-05:00 	kernel 	- 	pid 4814 (suricata), jid 0, uid 0: exited on signal 10 (core dumped)
2023-11-23 18:33:08.993276-05:00 	php-cgi 	81475 	[Suricata] The Rules update has finished.

                                  Rules update completed at 18:33:08. That crash happened at 19:14:37, or 41 minutes later.

                                  Other helpful information the next time this happens would be the content of the suricata.log file around the same time interval. You would need to capture that log BEFORE you restarted Suricata because that log is wiped clean each time Suricata is started or restarted in the GUI.

                                    @bmeeks These are the only logs available in the suricata.log file, and the immediately was reference to it being the next log in line. There was nothing else before the core dump other than the rukes reloading. It has not yet occurred again, so hopefully it is an isolated incident and won't occur again.

                                      For those of you having the Signal 11 or Signal 10 crashes, it would perhaps be useful if you can submit the core dump backtrace.

                                      The command to execute at a shell prompt is:

                                      gdb /usr/local/bin/suricata /root/suricata.core

                                      Then execute these commands within the gdb prompt:

                                      (gdb) bt
(gdb) bt full
(gdb) info threads
(gdb) thread apply all bt
(gdb) thread apply all bt full

                                      Capture the output of those commands and post it back here.

                                        No, I don't think that is a true statement. It should never have occurred in the first place. The fact it did indicates there is a problem, and so it will happen again. It's only the "when" that is unknown.

                                          @bmeeks I know it isnt likely, but can still be hopeful. I'll run the core dump commands on the next crash so I can provide them the next time it happens. Thanks for your help!

                                            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
