From b923c4dc9f011ab8f62e03211407d042dbe9f92a Mon Sep 17 00:00:00 2001 From: Nick Mathewson Date: Mon, 13 Feb 2017 09:10:11 -0500 Subject: Code to disable memory sentinels for fuzzing This feature makes it possible to turn off memory sentinels (like those used for safety in buffers.c and memarea.c) when fuzzing, so that we can catch bugs that they would otherwise prevent. --- changes/bug21439 | 7 +++++++ 1 file changed, 7 insertions(+) create mode 100644 changes/bug21439 (limited to 'changes/bug21439') diff --git a/changes/bug21439 b/changes/bug21439 new file mode 100644 index 0000000000..3acc53bfb7 --- /dev/null +++ b/changes/bug21439 @@ -0,0 +1,7 @@ + o Minor features (testing): + - Add a "--disable-memory-sentinels" feature to help with fuzzing. + When Tor is compiled with this option, we disable a number of + redundant memory-safety failsafes that are intended to stop + bugs from becoming security issues.
