[tor/maint-0.3.3] Make CacheDirectoryGroupReadable an autobool.

commit 4fd761a418558c05716b4a04a5306dc67ce53dfe Author: Nick Mathewson <nickm(a)torproject.org> Date: Mon Sep 17 11:36:59 2018 -0400 Make CacheDirectoryGroupReadable an autobool. Since the default cache directory is the same as the default data directory, we don't want the default CacheDirectoryGroupReadable value (0) to override an explicitly set "DataDirectoryGroupReadable 1". To fix this, I'm making CacheDirectoryGroupReadable into an autobool, and having the default (auto) value mean "Use the value of DataDirectoryGroupReadable if the directories are the same, and 0 otherwise." Fixes bug 26913; bugfix on 0.3.3.1-alpha when the CacheDirectory option was introduced. --- changes/ticket26913 | 7 +++++++ doc/tor.1.txt | 6 ++++-- src/or/config.c | 21 +++++++++++++++++++-- 3 files changed, 30 insertions(+), 4 deletions(-) diff --git a/changes/ticket26913 b/changes/ticket26913 new file mode 100644 index 000000000..d6555764e --- /dev/null +++ b/changes/ticket26913 @@ -0,0 +1,7 @@ + o Minor bugfixes (directory permissions): + - When a user requests a group-readable DataDirectory, give it to + them.
