Comment:
Closing after a clarifying chat with dgoulet. Thanks! In case someone runs
into this, this is what i understood (paraphrasing here):
That "400 Rejected" error is ambiguous (hence the fix is not to improve
the log message) and can be caused by two things today
- 1) Unable to decode the descriptor (which can be caused by many things)
or
- 2) Revision counter is lower than previous one
The reason for 2) could be a replay attack (in theory - "yes (if we rule
out a tor bug)") or an operator emptied the state file, or downgraded a
client from 0.3.5 to 0.3.4 as i did.
> in this case, going from 035 to 034 breaks it for ~3hr but then works
... so logging that one should maybe wait is not ideal because we don't
know the context
> in 034 HidServRevCounter is based on a value in the state file, 035+ is
based on time
The other option is being debugged in #27436.
