Subject: Increase timeout waiting for signal delivery to 2 seconds
X-Git-Tag: submit/tizen/20201019.101508~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F90%2F245890%2F1;p=platform%2Fcore%2Fsecurity%2Fsecurity-manager.git

Increase timeout waiting for signal delivery to 2 seconds

The prepare_app is synchronizing threads security attributes in app
candidate process, which can be multithreaded. Security-Manager's
implementation mimics implementation in libc for smack label synchronization,
using signal handlers to do that.

In some systems under heavy load current timeout we're waiting for signal
delivery can be not enough, hence increasing the timeout.
