Now that circid_t is 4 bytes long, the default integer promotions will leave it alone when sizeof(int) == 4, which will leave us formatting an unsigned as an int. That's technically undefined behavior. Fixes bug 8447 on bfffc1f0fc7616a25c32da2eb759dade4651659e.

commit 339df5df085e2115c01881cf628abe5ed3fbd456
I'm unable find change to this line in 339df5df085e2115c01881cf628abe5ed3fbd456. AFAICT, this line was introduced long ago in 2004 by a981c4099af25e8e38ca1fbe4870d09c54d0d20b (SVN commit) and never touched since then. I think we should dig deeper why does this happen (started to happen?). Is it a bug in tor that produces such duplicate cookies or it's in some independent/modified implementation. -- Ivan Markin

One of my guard relays has a few entries on Oct 06 also: Oct 06 09:04:00.000 [warn] Duplicate rendezvous cookie in ESTABLISH_RENDEZVOUS. Oct 06 09:04:00.000 [warn] Duplicate rendezvous cookie in ESTABLISH_RENDEZVOUS. Oct 06 10:17:30.000 [warn] Duplicate rendezvous cookie in ESTABLISH_RENDEZVOUS. Times are in UTC. Logs on this machine go back to Oct 03 but those are the only occurrences. My other guard relay with nearly identical specs and CW doesn't have these entries.

Several of those warnings here as well on Oct 06 - on exit as on non exit - at different times
I just checked the logs on my exit, the only warnings I have are the usual " 127.0.0.1:53 is down, All DNS servers are back up" messages. On Fri, Oct 7, 2016 at 2:00 PM, pa011 <pa011@web.de> wrote:

Sure, type of relay doesn't matter here since a rendezvous client picks random relay to act as Rendezvous Point. Somehow there are clients who send more than one ESTABLISH_RENDEZVOUS cell to the same relay with the same cookie. Most likely it's behavior of some alternative/modified tor implementation (since it started recently and at almost the same time?). At least I can't find a way little-t-tor is able to do this. -- Ivan Markin

Hello and thanks for reporting this issue! I opened a trac ticket about this, as that's a better way to handle little-t-tor bugs. Please feel free to contribute there: https://trac.torproject.org/projects/tor/ticket/20332 I took a brief look at the relevant code, and I'm also not sure what's causing the issue. More digging required.

I think one should emphasize that relay operators shouldn't worry about it since it's client(s) [hopefully not little-t-tor one(s)] who send such cells. Thanks everybody reporting about this issue! -- Ivan Markin
