[tor/maint-0.3.5] hs-v3: Silence some logging for client authorization
by nickm＠torproject.org 15 Nov '18

commit 18085abfcc3d13c53752764ea87a21201831bc6b Author: David Goulet <dgoulet(a)torproject.org> Date: Mon Sep 10 15:04:22 2018 -0400 hs-v3: Silence some logging for client authorization If a tor client gets a descriptor that it can't decrypt, chances are that the onion requires client authorization. If a tor client is configured with client authorization for an onion but decryption fails, it means that the configured keys aren't working anymore. In both cases, we'll log notice the former and log warn the latter and the rest of the decryption errors are now at info level. Two logs statement have been removed because it was redundant and printing the fetched descriptor in the logs when 80% of it is encrypted wat not helping.
