[JBoss JIRA] Created: (SECURITY-352) Cache Server Subject
by Darran Lofthouse (JIRA)
Cache Server Subject
--------------------
Key: SECURITY-352
URL: https://jira.jboss.org/jira/browse/SECURITY-352
Project: JBoss Security and Identity Management
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: Negotiation
Reporter: Darran Lofthouse
Assignee: Darran Lofthouse
Fix For: Negotiation_2.0.4.GA
Each authentication process currently has 3 AS-REQ requests (6 if pre-auth is an issue)
One request for each of the SPNEGO round trips and then one request for the LDAP search.
Attempts to make use of a local ticket cache failed: -
<!--
<module-option name="useTicketCache">true</module-option>
<module-option name="renewTGT">true</module-option>
<module-option name="ticketCache">/home/darranl/src/negotiation-as/jboss-4.2.2.GA-AD/testserver.cache</module-option>
-->
As the keytab had not been read it meant that the requirements for storeKey were not met, this is needed for SPNEGO.
<module-option name="storeKey">true</module-option>
A mechanism to cache the server subject is needed.
The expiration time of the ticket can be obtained to decide how long to cache the ticket for: -
Set<Object> privateCredentials = serverSubject.getPrivateCredentials();
for (Object current : privateCredentials)
{
if (current instanceof KerberosTicket)
{
KerberosTicket ticket = (KerberosTicket) current;
System.out.println(ticket.getEndTime());
}
}

[JBoss JIRA] Created: (JBRULES-1471) Accumulate should not call getResult() more then necessary
by Geoffrey De Smet (JIRA)
Accumulate should not call getResult() more then necessary
----------------------------------------------------------
Key: JBRULES-1471
URL: http://jira.jboss.com/jira/browse/JBRULES-1471
Project: JBoss Drools
Issue Type: Task
Security Level: Public (Everyone can see)
Components: Reteoo
Reporter: Geoffrey De Smet
Assigned To: Edson Tirelli
Fix For: 5.0.0-M1
For this rule:
rule "roomCapacityTooSmall" // TODO it takes 50-90% of the performance of drools-solver
when
$period : Period();
$room : Room($capacity : capacity);
$totalStudentSize : Number(intValue > $capacity) from accumulate(
Exam(period == $period, room == $room, $studentSize : topicStudentSize),
sum($studentSize)
);
...
end
Outside drl, I update 2 out of 700 Exam objects and call fireAllRulesAndCalculateDecisionScore.
The drl never changes an Exam. Period and Room never change.
That results into this log:
Breakpoint reached at org.drools.solver.core.evaluation.EvaluationHandler.fireAllRulesAndCalculateDecisionScore(EvaluationHandler.java:90)
Breakpoint reached at org.drools.base.accumulators.SumAccumulateFunction.reverse(SumAccumulateFunction.java:62)

Breakpoint reached at org.drools.base.accumulators.SumAccumulateFunction.getResult(SumAccumulateFunction.java:70)
Breakpoint reached at org.drools.base.accumulators.SumAccumulateFunction.reverse(SumAccumulateFunction.java:62)

Breakpoint reached at org.drools.base.accumulators.SumAccumulateFunction.accumulate(SumAccumulateFunction.java:53)
Breakpoint reached at org.drools.base.accumulators.SumAccumulateFunction.getResult(SumAccumulateFunction.java:70)
There are 4 accumulate calls and 4 reverse calls. That might be accurate.
There are 8 getResult calls, that should only be 1.
Also, the getResult method creates a new Double instance each time:
return new Double( data.total );
It might be better to do
return Double.valueOf(data.total);
to allow the JVM to hot spot optimize it.

[JBoss JIRA] Created: (JBRULES-946) RuleBase serialization fails with StackOverflowError
by Alexandre Gattiker (JIRA)
RuleBase serialization fails with StackOverflowError
----------------------------------------------------
Key: JBRULES-946
URL: http://jira.jboss.com/jira/browse/JBRULES-946
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 4.0.0.MR2
Reporter: Alexandre Gattiker
Assigned To: Mark Proctor
I created 920 rules, all in this format, with different values in the string literals.
rule "Rule_1"
when
$g:Parent()
$c:Child(parent==$g,code=="yyy1")
Item(parentObject==$c,name=="xxx1", value == "1")
Item(parentObject==$c,name=="xxx2",value == "1")
Item(parentObject==$g,name=="xxx3",value == "200")
then
System.out.println("2");
end
With the following code, I create a RuleBase that I serialize.
RuleBase ruleBase = RuleBaseFactory.newRuleBase();
PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
conf.setCompiler(PackageBuilderConfiguration.JANINO);
Reader source = new InputStreamReader(PolicyServiceImpl.class.getResourceAsStream(fileName));
PackageBuilder builder = new PackageBuilder(conf);
builder.addPackageFromDrl(source);
Package pkg = builder.getPackage();
ruleBase.addPackage(pkg);
//serialize RuleBase
File outFile = new File(f.getPath() + ".tmp");
FileOutputStream fout = new FileOutputStream(outFile);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(ruleBase);
oos.close();
The serialization fails with the following exception. Otherwise the RuleBase is perfectly fine and working.
