Bertrand Delacretaz commented on SLING-5135:
--------------------------------------------
bq. ...I suppose calls to
ResourceResolverFactory.getAdministrativeResourceResolver ultimately end up in
a call to loginAdministrative which is subject to the whitelist?
That's not the case - calls to {{getAdministrativeResourceResolver()}} end up
calling {{repository.loginAdministrative(null)}} in {{JcrProviderStateFactory}}
which uses a {{SlingRepository}} service acquired by the
{{JcrResourceProvider}} service. The reference client bundle for the whitelist
is then the {{o.a.s.jcr.resource}} bundle even if it's another bundle which
called {{getAdministrativeResourceResolver()}}, hiding the actual client bundle
from the whitelist.
To fix this and take the whitelist into account for
{{getAdministrativeResourceResolver()}} calls which end up hitting the
{{JcrResourceProvider}} we need to modify that service so that it's registered
with a custom {{ServiceFactory}} which stores a reference to the client bundle
that's using the {{JcrResourceProvider}} service, as is done in
{{AbstractSlingRepositoryManager.registerService()}}. That client bundle
reference can then be passed to {{JcrProviderStateFactory}} so that the
{{LoginAdminWhitelist}} can be used there, evaluated against the correct client
bundle.
That's a somewhat complicated explanation - as I said I probably won't have
time to work on this right now, so saving this knowledge for later ;-)
