Add linked-on-or-after checks for network process blob file URL checking
https://bugs.webkit.org/show_bug.cgi?id=281798
rdar://137326900
Reviewed by Brent Fulgham.
281966@main introduced checks in the network process that verify blob URLs are
allowed to be
read by a certain web process before reading them. This required introducing
IPC roundtrips
between the UI process and network process. However, the introduction of these
IPC roundtrips
subtly changed the callback sequence, and apps that rapidly call
WKWebView.loadData, loadFileURL,
and loadRequest without waiting for them to finish and responding to
WKNavigationDelegate's
decidePolicyForNavigationAction and decidePolicyForNavigationResponse with
...PolicyCancel
based on the callback sequence now sometimes cancel the wrong load. To keep
these apps working
until they update, I introduce a linked-on-or-after check for the IPC
roundtrips and the
check in the network process they facilitate.
