[tor/release-0.3.1] Move destroy cells into a separate queue type of their own, to save RAM

commit 520cf21793e9c6b662c76c02235315f898d10fb9 Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue Dec 19 13:53:52 2017 -0500 Move destroy cells into a separate queue type of their own, to save RAM We've been seeing problems with destroy cells queues taking up a huge amount of RAM. We can mitigate this, since while a full packed destroy cell takes 514 bytes, we only need 5 bytes to remember a circuit ID and a reason. Fixes bug 24666. Bugfix on 0.2.5.1-alpha, when destroy cell queues were introduced. --- changes/bug24666 | 7 ++++ src/or/circuitmux.c | 34 +++++-------------- src/or/circuitmux.h | 2 +- src/or/or.h | 15 +++++++++ src/or/relay.c | 82 ++++++++++++++++++++++++++++++++++++++++++++-- src/or/relay.h | 8 +++++ src/test/test_circuitmux.c | 12 +++---- 7 files changed, 126 insertions(+), 34 deletions(-) diff --git a/changes/bug24666 b/changes/bug24666 new file mode 100644 index 000000000..830775f5f --- /dev/null +++ b/changes/bug24666 @@ -0,0 +1,7 @@ + o Minor bugfixes (memory usage): + + - When queuing DESTROY cells on a channel, only queue the + circuit-id and reason fields: not the entire 514-byte + cell.
