Seth Hall commented on BIT-1333: -------------------------------- The new behavior is correct. We changed how the file framework handles files a bit in the core and part of this was breaking out the file type identification. > 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 > Assignee: Seth Hall > > * 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
