#29699: INTRO2 replay warn logs with v3 onions ------------------------------+-------------------- Reporter: mikeperry | Owner: (none) Type: defect | Status: new Priority: Medium | Milestone: Component: Core Tor/Tor | Version: Severity: Normal | Keywords: Actual Points: | Parent ID: Points: | Reviewer: Sponsor: | ------------------------------+-------------------- While testing vanguards 0.3.0 with tor 0.4.0.2-alpha and a v3 onion service that was only for my testing, I got several loglines to the effect of
{{{ Mar 07 11:10:17.000 [info] hs_circ_handle_introduce2(): We received an INTRODUCE2 cell with same REND_COOKIE field 1 seconds ago. Dropping cell. Mar 08 12:05:58.000 [warn] Possible replay detected! An INTRODUCE2 cell with thesame ENCRYPTED section was seen 0 seconds ago. Dropping cell. Mar 08 14:17:21.000 [warn] Possible replay detected! An INTRODUCE2 cell with thesame ENCRYPTED section was seen 59 seconds ago. Dropping cell. }}} The client was Tor version 0.3.5.7 (git-9beb085c10562a25), from Tor Browser 8.0.6. The client was accessing the service as follows: {{{ while [ true ]; do torsocks wget http://$MYV3_ONION_NAME.onion/404 -O /dev/null killall -HUP tor; done }}} That v3 404 url is in fact non-existant -- it does just send back a HTTP 404. I'll match up some log instances and attach. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/29699> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
