[tor/maint-0.2.5] Fix a traceback when closing a blocked connection "immediately".

commit 95238eb9174f0cfee9d313ce15b4f9b471f3d0e5 Author: Nick Mathewson <nickm(a)torproject.org> Date: Thu Nov 16 11:45:15 2017 -0500 Fix a traceback when closing a blocked connection "immediately". When we close a connection via connection_close_immediately, we kill its events immediately. But if it had been blocked on bandwidth read/write, we could try to re-add its (nonexistent) events later from connection_bucket_refill -- if we got to that callback before we swept the marked connections. Fixes bug 24167. Fortunately, this hasn't been a crash bug since we introduced connection_check_event in 0.2.9.10, and backported it. This is a bugfix on commit 89d422914a0c3cb, I believe, which appeared in Tor 0.1.0.1-rc. --- changes/bug24167 | 7 +++++++ src/or/connection.c | 4 ++++ 2 files changed, 11 insertions(+) diff --git a/changes/bug24167 b/changes/bug24167 new file mode 100644 index 000000000..fd0d87eff --- /dev/null +++ b/changes/bug24167 @@ -0,0 +1,7 @@ + o Minor bugfixes (network layer): + - When closing a connection via close_connection_immediately(), we + mark it as "not blocked on bandwidth", to prevent later calls + from trying to unblock it, and give it permission to read.
