Paul Pearce created BIT-1333: -------------------------------- Summary: Bro's ASCII logging facilities do not escape escape characters Key: BIT-1333 URL: https://bro-tracker.atlassian.net/browse/BIT-1333 Project: Bro Issue Tracker Issue Type: Problem Components: Bro Affects Versions: 2.3 Reporter: Paul Pearce
* Bro escapes non-printable ASCII characters with either \x?? or ^ depending on the character (https://www.bro.org/sphinx/scripts/base/bif/strings.bif.bro.html). * Bro does not however escape \ or ^. * This behavior makes recovering the original string impossible as you can not differentiate between an escaped sequence and a string containing those characters. Examples: $ bro -e 'event bro_init() { print "foo \xc2\xae bar \\xc2\\xae baz"; }' foo \xc2\xae bar \xc2\xae baz $ bro -e 'event bro_init() { print "foo\x00bar\\0baz"; }' foo\0bar\0baz $ bro -e 'event bro_init() { print "foo \16 bar ^N baz"; }' foo ^N bar ^N baz Additionally, it would be ideal if there was a way to standardize escaping to a single syntax (\x?? for all, for example). This would allow post-processing of the bro logs in languages like Python or Ruby trivially using existing decode/encode functionality. I'm happy to file a separate feature request for this behavior, if that is preferred. I brought this up on the mailing list (http://mailman.icsi.berkeley.edu/pipermail/bro/2015-February/008174.html). It was suggested (off list) that I file a ticket as well. -- This message was sent by Atlassian JIRA (v6.4-OD-15-055#64014) _______________________________________________ bro-dev mailing list bro-dev@bro.org http://mailman.icsi.berkeley.edu/mailman/listinfo/bro-dev
