#3695 closed defect (fixed)

Handling of ISO_STREAM is bogus

Severity: Keywords: tor-client
Cc: nickm, katmagic Actual Points:

Reviewer: Sponsor:


connection_edge_compatible_with_circuit prevents a stream with ISO_STREAM set from being associated to any circuit to which a stream (not necessarily a different stream) has already been associated. Nothing else looks at ISO_STREAM. (In other news, connection_edge_streams_are_compatible is dead code.)

This treatment of ISO_STREAM should cause excess circuit creation (#3632) during anonymous directory operations, and it does not (explicitly) prevent a circuit which has had an ISO_STREAM stream attached to it from having a non-ISO_STREAM stream attached to it later.

See fix-ISO_STREAM ( fix-ISO_STREAM ) for a (not-yet-tested) fix.

Nice catch!

Can we make the logic more uniform? (See branch "fix-ISO_STREAM" in my public repo)

Resolution: fixed

rransom liked it except for a comment, so I'll fix that, squash, and merge.
