Description

I started seeing this error while making .conf file modifications to drop a flowbit rule. Even after renaming disable.conf, drop.conf, and modify.conf so they will no longer be applied it still occurs. Unclear what's causing it /wo any of my modified config applied anymore.

At least one thing that's weird in the debug logs, are the multiple misaligned counts of flowbit rewquirements...

I've been able to get this to re-occur, but I'm still unclear of the specifics. Seems to have something to do with adding / removing the following in order to disable a flowbit rule:

modify.conf:
1:2018959 "flowbits:.*;" ""

disable.conf
1:2018959

Guessing this is due to the modify rule using a greedy match, which replaced many parts of the rule and not just the flowbits portion of the rule. Which likely resulted in a rule without a SID.

  • Warnings should be output for such rather than crashing.
  • Something else weird is occurring, as removing that modify.conf line would not resolve the issue after it occured; perhaps related to parsing of backup files

Correct. suricata-update uses python re library, see here: https://docs.python.org/3/library/re.html

It mentions about the '*' character that it does a greedy match and for your regex, it tends to remove everything after the flowbits, to avoid that, use 

1:2018959 "flowbits:.*?;" ""
. This seems to be working fine on my end, let me know if this seems to be failing for your usecase.

  • Warnings should be output for such rather than crashing.

In the latest master if you'll check, we raise an exception with a clearer message for such cases however, it is not a regular output, it is a traceback since sid is crucial for any rule.

raise BadSidError("Sid cannot be of type null")
suricata.update.rule.BadSidError: Sid cannot be of type null
  • Something else weird is occurring, as removing that modify.conf line would not resolve the issue after it occured; perhaps related to parsing of backup files

Yes, the code to overwrite the old rule file was never executed because of the error. This has also been fixed in the latest master with the exception as mentioned above.

So, in case regex is incorrect, its fairly hard to figure out with code unless it is something that causes major damage. If you have any suggestions for dealing with such situations, they're very welcome.
