      i was thinking the same, i see no relationship to the Legacy Blocking Module, the only reference on gdb about alert-pf is on thread 2

      Thread 2 (LWP 179039 of process 2511 "IM#01"):
      #0 0x00000008029807ea in _read () from /lib/libc.so.7
      #1 0x00000008021f4a13 in ?? () from /lib/libthr.so.3

      but the one throwing the error is Thread 8

      Thread 8 (LWP 187487 of process 2511 "W#05"):

          @bmeeks

          suricata.yaml.txt

          Thanks! If you can post the suricata.rules file from the interface, that would be useful, too.

          I would really love to be able to reproduce the crash, but if not I can compile a 4.2.0 Hyperscan library that you can try just for giggles.

          The error returned by Hyperscan is actually quite specific. Here are the associated comments:

          hs_error_t err = hs_scan(sctx->db, (const char *)haystack, haystack_len, 0,
                                      scratch, MatchEvent, &match_offset);
             if (err != HS_SUCCESS && err != HS_SCAN_TERMINATED) {
                 /* An error value (other than HS_SCAN_TERMINATED) from hs_scan()
                  * indicates that it was passed an invalid database or scratch region,
                  * which is not something we can recover from at scan time. */
                 SCLogError("Hyperscan returned fatal error %d.", err);
                 exit(EXIT_FAILURE);
             }
          

          This indicates to me that Suricata is passing Hyperscan either an invalid database or an invalid scratch memory area. What is strange, though, is that no other users on Linux are reporting this kind of issue. At least I have not found such a report.

                @kiokoman:
                Imported your suricata.yaml configuration and suricata.rules file into my virtual machine. Only edited the interface names to reflect em0 which is what I use in my virtual machine at the moment.

                Suricata starts up and runs. No error yet. Will let it run for a while to see if a crash occurs. I suspect my little VM is not seeing the same amount of packets (traffic) as your machine, though.

                  i tried to compile hyperscan 5.4.2 but it does not work with suricata, coredump with "ipprotos" not found or something

                  with 5.2.1 i have assertion failed ...

                  i must have done something wrong

                  if you can compile a different hs library version i can try it

                  changing from AutoFP to Worker make no difference

                    @bmeeks,

                    I loaded the Suricata package that you provided. I did not disable ASLR, so when I started Suricata with pattern matcher set to to "Auto", the PC interface Suricata instance immediately crashed. Below is the gdb output you asked for.

                      @bmeeks,

                      I loaded the Suricata package that you provided. I did not disable ASLR, so when I started Suricata with pattern matcher set to to "Auto", the PC interface Suricata instance immediately crashed. Below is the gdb output you asked for.

                      Core was generated by `/usr/local/bin/suricata -i vtnet0.700 -D -c /usr/local/etc/suricata/suricata_238'.
                      Program terminated with signal SIGSEGV, Segmentation fault.

                      Thank you. This crash is similar to @kiokoman's core dump. Suricata seems to be doing something improper within the App Layer protocols logic. In your case it is causing a Signal 11 segfault, but in his case it simply results in the Hyperscan library stopping on a passed-in parameter validation check which leads to Suricata shutting down with a Fatal Error. I may need to raise this again with upstream.

                      Still puzzled why I can't seem to reproduce it -- at least not yet.

                          While not exactly the same, the failure locations I see in both of the suricata.core file back trace results look eerily like this old bug in that the failure is in the app-layer protocols section: https://redmine.openinfosecfoundation.org/issues/4273.

                          I wonder if there still might be an issue lurking in the logic even though the originally reported bug was fixed ??

                          I've sent both back trace results and @kiokoman's gdb.txt dump to the upstream developers asking for any insights they may have.

                                  Your file dates are weird. June 30 for 2.7.2 files is too early. Mine show December 16 dates, which coincides with the day I updated this particular VM to 2.7.2 CE.

                                  My file sizes agree 100% with those posted by @kiokoman. Your file dates of June 30 agree with the rollout of pfSense 2.7.0 CE. The 2.7.1 CE was released in November of this year.

                                  You might want to remove the Suricata package from your VM, then run this command to be sure the Hyperscan library is also removed:

                                  pkg info hyperscan
                                  

                                  If anything other than something like "not installed" comes back, then manually remove Hyperscan with this command:

                                  pkg delete hyperscan
                                  

                                  You having an older library might be why you are getting the segfault instead of the same fatal error -1 termination that @kiokoman and most others are seeing.

                                  Now reinstall Suricata and you should get the correct latest Hyperscan library.

                                    @bmeeks, I now have the same file sizes and dates. Would you like me to again load the debug package or do you have all that you need now?

                                      It would be interesting to see if now instead of a segfault you get the fatal error termination that @kiokoman is seeing.

                                      You do not have to install the debug package version for that test unless you just want to. I'm hoping maybe your segfault was an issue with the library compilation (being possibly from an older pfSense kernel build) and not a different manifestation of the same Hyperscan error.

                                      So, just set the Pattern Matcher to Auto and attempt to start Suricata. If it dies immediately (or later), check the suricata.log file to see if you have the "Hyperscan returned fatal error -1" message. If you still get a Signal 11 segfault in the system log, then color me thoroughly flummoxed 😁.

                                          @Negan I've had similar in other php files and these seem to be related to trying to do too much compared to the memory allocated for PHP. Were you trying to load a very large log file in Suricata Logs View? May be related to the specific interface and log type.

                                          I'm no expert on this, so someone else may correct me, but maybe look at the log size and rotation settings for that interface and lower them so they cycle out more frequently, especially if it is a really busy interface?

                                            Your probably right, just never seen this after Suricata crashed before.....
