Log Message

Restrict information passed with navigation action which is triggered by untrusted event
https://bugs.webkit.org/show_bug.cgi?id=154571
<rdar://problem/15967937>

Reviewed by Andy Estes.

Source/WebKit/mac:

* WebCoreSupport/WebFrameLoaderClient.mm:
(WebFrameLoaderClient::actionDictionary):

Source/WebKit2:

When navigation action is triggered by an untrusted event, we should be more restricted of
what information should be passed to the clients to lower the risk that clients could
be fooled by the untrusted event.

In this patch, we drop the modifiers for key state events and set the mouse button to NoButton
for mouse events.

* WebProcess/InjectedBundle/InjectedBundleNavigationAction.cpp:
(WebKit::InjectedBundleNavigationAction::modifiersForNavigationAction):

Tools:

* TestWebKitAPI/TestWebKitAPI.xcodeproj/project.pbxproj:
* TestWebKitAPI/Tests/mac/IsNavigationActionTrusted.mm: Added.
(-[WKNavigationActionDelegate webView:decidePolicyForNavigationAction:decisionHandler:]):
(TestWebKitAPI::TEST):
(-[NavigationActionDelegate webView:decidePolicyForNavigationAction:request:frame:decisionListener:]):
* TestWebKitAPI/Tests/mac/IsNavigationActionTrusted.html: Added.
