Comment:
Design Comments:
I would feel more comfortable if we rounded down each TTL received from a
DNS server, to avoid tagging attacks.
But I think that's probably a separate ticket, split off into #19769.
I'd like to merge both tickets in the same release, so that we only ever
send rounded values for IPv4 and IPv6 TTLs.
Code Review:
This is a 2-line patch, that we really should put in 0.2.9 with #19769 if
we can.
(It seems that #19769 would also be a very small change.)
It needs a changes file tor/changes/bug19025, matching the format of the
other bug* files in that directory. It could easily be created using
ticket and the commit comment.
phw, do you want to do the changes file? Do you want to do #19769?
I'm happy to do either.
