Subject: fix: crash loading non-standard schemes in iframes
This fixes a crash that occurs when loading non-standard schemes from
iframes or webviews. This was happening because
ChildProcessSecurityPolicyImpl::CanAccessDataForOrigin contains explicit
exceptions to allow built-in non-standard schemes, but does not check
for non-standard schemes registered by the embedder.
This patch adjusts the origin calculation for subframe non-standard schemes in
- browser process at `NavigationRequest::GetOriginForURLLoaderFactoryUncheckedWithDebugInfo`
- render process at `DocumentLoader::CalculateOrigin`
When top level frame navigates to non-standard scheme url, the origin is calculated
as `null` without any derivation. It is only in cases where there is a `initiator_origin`
then the origin is derived from it, which is usually the case for renderer initiated
navigations and iframes are no exceptions from this rule.
The patch should be removed in favor of either:
- Remove support for non-standard custom schemes
- Register non-standard custom schemes as websafe schemes and update
CPSPI::CanAccessDataForOrigin to allow them for any navigation.
- Update the callsite to use RFHI::CanCommitOriginAndUrl in upstream, previous
effort to do this can be found at https://chromium-review.googlesource.com/c/chromium/src/+/3856266.
Upstream bug https://bugs.chromium.org/p/chromium/issues/detail?id=1081397.
