commit 1dc21b87904b527140446674876076f29c78b89f Author: George Kadianakis <desnacked(a)riseup.net> Date: Wed Aug 30 15:29:41 2017 +0300 prop224: Simplify HSDir set change algo. Our logic for detecting hsdir set changes was needlessly compicated: we had to sort smartlists and compare them.

[tor/master] prop224: Clear list of prev hsdirs before we upload all descs.
by nickm＠torproject.org 04 Sep '17

commit b9f849bdee20f36264fe061498536e0d3a8616a6 Author: George Kadianakis <desnacked(a)riseup.net> Date: Tue Aug 29 16:02:01 2017 +0300 prop224: Clear list of prev hsdirs before we upload all descs. This fixes a serious bug in our hsdir set change logic: We used to add nodes in the list of previous hsdirs everytime we uploaded to a new hsdir and we only cleared the list when we built a new descriptor. This means that our prev_hsdirs list could end up with 7 hsdirs, if for some reason we ended up uploading our desc to 7 hsdirs before rebuilding our descriptor (e.g. this can happen if the set of hsdirs changed). After our previous hdsir set had 7 nodes, then our old algorithm would always think that the set has changed since it was comparing a smartlist with 7 elements against a smartlist with 6 elements. This commit fixes this bug, by clearning the prev_hsdirs list before we upload to all hsdirs. This makes sure that our prev_hsdirs list always contains the latest hsdirs! --- src/or/hs_service.c | 4 ++++ src/test/test_hs_common.c | 4 ++-- 2 files changed, 6 insertions(+), 2 deletions(-) diff --git a/src/or/hs_service.c b/src/or/hs_service.c index 0fba0d7f9..218d49ace 100644 --- a/src/or/hs_service.c +++ b/src/or/hs_service.c @@ -2316,6 +2316,10 @@ upload_descriptor_to_all(const hs_service_t *service, hs_get_responsible_hsdirs(&desc->blinded_kp.pubkey, desc->time_period_num, for_next_period, 0, responsible_dirs); + /** Clear list of previous hsdirs since we are about to upload to a new + * list.
