commit d10ceb7165effc30d38edbbe370f311c4719d2b6 Author: Nick Mathewson <nickm@torproject.org> Date: Thu Oct 14 12:21:30 2021 -0400 Downgrade "Rejecting RENDEZVOUS1 cell with unrecognized cookie" This is the loudest of our LOG_PROTOCOL_WARN messages, it can occur naturally, and there doesn't seem to be a great response to it. Partial fix for 40400; bugfix on 0.1.1.13-alpha. --- changes/bug40400_part2 | 5 +++++ src/feature/rend/rendmid.c | 6 +++++- 2 files changed, 10 insertions(+), 1 deletion(-) diff --git a/changes/bug40400_part2 b/changes/bug40400_part2 new file mode 100644 index 0000000000..9b834d5ea1 --- /dev/null +++ b/changes/bug40400_part2 @@ -0,0 +1,5 @@ + o Minor bugfixes (usability): + - Do not log "RENDEZVOUS1 cell with unrecognized rendezvous cookie" + at LOG_PROTOCOL_WARN; instead log it at DEBUG.
