Hi FIWARE Tech Crew,
We have issue with one of the enablers and we are trying to get support. Its related to the access control generic enabler.
Below is the issue:
We have problem with PAP PolicySet update, when i make request for update PolicySet i got response OK and new PolicySet works fine, but when i try to get PolicySet i got old PolicySet data.
To check what is problem i tried to tail on PolicySet xml file and got file reverted to old version, after regular file update.
This is dump from tail:
tail -f policySet.xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<PolicySet xmlns="urn:oasis:names:tc:xacml:3.0:core:schema:wd-17" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Red coloured part is value before i make update, blue coloured part is after update is executed, and this green coloured part is problem part.
Do you have any idea why policy file is reverted to the original value automatically?
We believe that in SecurityDomain.Java, method setPolicySet has problem with finally block:
public void setPolicySet(PolicySet policySet) throws IOException, JAXBException
{
// before changing policy, backup current policy
FileUtils.copyFile(this.policySetFile, this.policySetBackupFile);
final Marshaller marshaller;
try
{
marshaller = PdpModelHandler.XACML_3_0_JAXB_CONTEXT.createMarshaller();
marshaller.setSchema(authzApiSchema);
marshaller.setProperty(Marshaller.JAXB_ENCODING, UTF8_JAXB_ENCODING);
marshaller.marshal(policySet, policySetFile);
} catch (JAXBException e)
{
// Replace back with backup in case the file is corrupted due to this exception
FileUtils.copyFile(this.policySetBackupFile, this.policySetFile);
throw new JAXBException("Error marshalling new domain policy to file: " + this.policySetFile.getAbsolutePath(), e);
}
// try updating PDP with new policy
try
{
// TODO: optimization: load policy directly from PolicySet arg (requires changing
// Sunxacml StaticPolicyFinderModule code)
updatePDP(true, null);
} finally
{
FileUtils.copyFile(this.policySetBackupFile, this.policySetFile);
}
}
Issue is because they put backup file back although everything was ok - My assumption is that there should be catch instead of finally??
We reported issue 10 days ago and recently we got response from Mr Cyril that we need to write to this email?! Also mr. Cyril asked for XML file dump (not sure why), we put it below.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><PolicySet xmlns="urn:oasis:names:tc:xacml:3.0:core:schema:wd-17" xmlns:ns2="http://thalesgroup.com/authzforce/pdp/model/2014/12" PolicySetId="default" Version="1.0" PolicyCombiningAlgId="urn:oasis:names:tc:xacml:1.1:policy-combining-algorithm:ordered-permit-overrides"><Target/><Policy PolicyId="permit-all" Version="1.0" RuleCombiningAlgId="urn:oasis:names:tc:xacml:1.1:rule-combining-algorithm:ordered-permit-overrides"><Target/><Rule RuleId="deny-all" Effect="Deny"/></Policy></PolicySet>
Hopefully we will get support asap,
Best Regards,
Dino

* Please describe the use case for which you intend to use the FIWARE Authorization PDP.
We use Authorization PDP to manage policies (which we later use in Access COntrol)
* What type of service do you want to control access to? (Protocol, API... e.g. HTTP/REST)
HTTP REST
* You can now formulate your request, at last :)
We have problem with PAP PolicySet update, when i make request for update PolicySet i got response OK and new PolicySet works fine, but when i try to get PolicySet i got old PolicySet back.
To check what is problem i tried to tail on PolicySet xml file directly in the file system and got file reverted to old version, after regular file update.
This is dump from tail:
tail -f policySet.xml
PolicySetId="default" Version="1.0"
PolicyCombiningAlgId="urn:oasis:names:tc:xacml:1.1:policy-combining-algorithm:ordered-permit-overrides">
## after update happnes (we call rest service):
tail: policySet.xml: file truncated
RBAC Policy
Employee Role PolicySet
EmployeePPS:Employee_Role
Manager Role PolicySet
ManagerPPS:Manager_Role
Default Deny policy
##after update is done we see that somehow file is back to the original version:
tail: policySet.xml: file truncated
PolicySetId="default" Version="1.0"
PolicyCombiningAlgId="urn:oasis:names:tc:xacml:1.1:policy-combining-algorithm:ordered-permit-overrides">
.
To complete, please give me some contact information so that we can get back to you.
