#26846: prop289: Leave unused random bytes in relay cell payload ------------------------------------------+-------------------------------- Reporter: dgoulet | Owner: dgoulet Type: enhancement | Status: assigned Priority: Medium | Milestone: Tor: | 0.3.5.x-final Component: Core Tor/Tor | Version: Severity: Normal | Resolution: Keywords: prop289, 035-roadmap-subtask | Actual Points: Parent ID: #26288 | Points: Reviewer: | Sponsor: SponsorV ------------------------------------------+--------------------------------
Comment (by arma): The first step here is confirming that indeed the rolling circuit cell digest covers all of the bytes in the cell, not just the "in use" (rh->length) ones. I think we're good there: see the two calls to crypto_digest_add_bytes() in relay_crypto.c that have CELL_PAYLOAD_SIZE as their size argument. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/26846#comment:2> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
