I used to filter on bytes strings like

tcp[12:2,14:2]==a012:111c

and get a Invalid filter:"111c" was unexpected in this context in the new release

Is that intended or a bug ? Regards Matthias

Probably best to raise an issue at GitLab for this, there have been a lot of changes in the filtering code that this might be an unintended regression.

Created #18227 as a GitLab issue.

As per the discussion in GitLab item #18227 the filter parser no longer supports the colon separating 2-byte strings

The parser now rejects 1503:03 as an invalid byte string. This must be written 150303 or 15:03:03.

I thinks this has always been supposed to be tcp[12:2,14:2]==a0:12:11:1c, but never enforced. It's being enforced now.
