From: phweiss Date: Wed, 19 Apr 2017 18:15:06 +0000 (+0200) Subject: Implement CACert queries in SecurityController X-Git-Tag: android-x86-9.0-r1~1044^2~892^2 X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=7eeab2cdd99f84ecef12ebbb92e0731b26508da1;p=android-x86%2Fframeworks-base.git Implement CACert queries in SecurityController Cherry-pick note: testCACertLoader() was flaky, so this cherry-pick contains two attempted fixes and a CL that disables the test. The original commit messages of the squashed CLs are below. Merged-In: I3b9cc3d85c9f49d0a892613b63d1fba184ab647e Implement CACert queries in SecurityController Queries are run (on a AsyncTask) when user is switched and when ACTION_TRUST_STORE_CHANGED is broadcasted. Otherwise, the result is cached in the SecurityController.
