[torspec/master] Clarifications for extrainfo desc transport lines
by nickm＠torproject.org 09 Aug '12

09 Aug '12

commit 904d3d45583e9f916c74fab77784184defe53598 Author: Damian Johnson <atagar(a)torproject.org> Date: Sat Aug 4 19:57:22 2012 -0700 Clarifications for extrainfo desc transport lines Couple clarifications from discussions with asn... 1. The 'transportname' in descriptor lines are unique As discussed on ticket #6257, George is fine with the 'transportname' being unique per a descriptor. This is useful to me because I can now model this as a 'transportname => attributes' hash which will be more user friendly. 2. The transport name can appear on non-bridges Though this attribute only makes sense for bridges, it can appear on the extrainfo descriptors for non-bridges as well. Actually, we already have one in the wild... extra-info toorvoid 0B37323298FF98CD86ED404895BB27B7426E8AE1 published 2012-08-04 12:19:13 transport obfs2 83.212.96.201:33570 --- dir-spec.txt | 7 ++++++- 1 files changed, 6 insertions(+), 1 deletions(-) diff --git a/dir-spec.txt b/dir-spec.txt index f88ceb3..c18efcf 100644 --- a/dir-spec.txt +++ b/dir-spec.txt @@ -891,7 +891,12 @@ [Any number.] Signals that the router supports the 'transportname' pluggable - transport in IP address 'address' and TCP port 'port'. + transport in IP address 'address' and TCP port 'port'.

[tor/master] Detect bug 6252 (unexpected sendme cell)
