Problems with SSL filters

[GoogleCodeExporter]

Can you please help me out to resolve this problem on using SSL(OpenSSL) 
transport filter?
I'm tring to send 512KB of data to server, and receive back the same amount of 
data.

Thanks.

Setup of SSL filter on client:
filterPtr.reset( new RCF::OpenSslEncryptionFilter(
        clientCert,
        clientCertPass,
        caCert);

getClientStub().requestTransportFilters(filterPtr);

Setup of SSL service and filter on server:
    filterServicePtr = RCF::FilterServicePtr(new RCF::FilterService());

    server.addService(filterServicePtr);

    filterServicePtr->addFilterFactory(
        RCF::FilterFactoryPtr( new RCF::OpenSslEncryptionFilterFactory(
        serverCert,
        serverCertPass,
        caCert)));

and remote call looks like this:

    BOOL processCmd(std::string &s)
    {
        if(IsTransportSecured(RCF::getCurrentRcfSession()))
        {       
            cout << "ByteBuffer has been received" << endl;
            char *bufToSend = new char[512*1024];
            memset(bufToSend, 0, 512*1024);

            for(int i = 0; i < 512*1024; i++)
            {
                srand(i);
                bufToSend[i] = rand(); 
            }

            s = std::string(bufToSend, 512*1024);
            return TRUE;
        }
        else
        {
            RCF::getCurrentRcfSession().disconnect();
        }

        return FALSE;
    }

First of all I get the assert window with the following info:
---------------------------

I've done some testing, and was able to send 1 MB messages back and forth 
between client and server, with the OpenSSL filter, 100 times, without any 
problems.

I'm using RCF 1.3, which may make a difference. Can you try with 1.3 
(http://deltavsoft.com/w/download.html) , and see if you still get the error?

[GoogleCodeExporter]

Then I don't really understand why by disabling OpenSSL transport filters I see 
no problems in the same test application.
Can you please send me your sample client/server implementation which sends 1mb 
of data back and forth over openssl transport filter.
I'm using RCF-1.3 and openssl-0.9.8o.

Thanks.

I get the stack overflow when running your sample.
The exception occurs right when client.echo(s0) is called in "sending large 
messages" block.

Here is the sample output:

The test code works on my machines, but there are some environmental 
differences, in particular I don't think we're using the same version of 
OpenSSL.

The stack trace shows pretty clearly what is going on though. I've fixed the 
stack recursion that is causing the overflow - if you apply the attached patch 
to RCF 1.3, it should take care of the issue.

I'm using OpenSSL 0.9.7c in my testing environment...

[GoogleCodeExporter]

Hello,

The patch did really fix the problem with recursion, thanks.
But I'm having another issue sending big chunks of data over SSL.
Can you please try to split client and server into different projects and run 
separately?
Your OpenSSL filter sample works OK when client/server are started within one 
application. 
But if you try to start them separately the client chokes up with the following 
exception after iterating over several times, sending 1MB data.
Please note I'm using Win32 Named Pipes as a transport.

If I skip the exception below, I get the following error message from the 
client.echo() call:
Failed to echo: [75] Pipe error. OS: 109 - The pipe has been ended.

And here is the stack trace when I get the exception:

I've split the test code into separate client and server processes, but am 
unable to reproduce the error... The code is attached - you can try to run it 
in your environment.

Thanks for the sample.
The only difference I found in my code is that I setup thread pool right before 
starting the server:

std::size_t targetThreadCount = 1;
std::size_t maxThreadCount = 100;
std::string threadName = "RCF Server";
boost::uint32_t threadIdleTimeoutMs = 60*1000;

RCF::ThreadPoolPtr threadPoolPtr( 
    new RCF::ThreadPool(
    targetThreadCount, 
    maxThreadCount,
    threadName,
    threadIdleTimeoutMs) );
server.setThreadPool(threadPoolPtr);
server.start();

Can you please try to add this piece of code in your SslServer process and let 
me know if you can reproduce the error.
I get RCF::Exception with error code 232(The pipe is being closed.) after 
several iterations on the client side. If no thread pool is used, then I don't 
get any exceptions.

thanks.

Thanks, that did the trick... There was a thread safety problem in the OpenSSL 
filter, easy enough to fix. I'm attaching an updated version of 
OpenSslEncryptionFilter.cpp, that should fix the problem.

[GoogleCodeExporter]

Have you rebuilt your server with the updated OpenSslEncryptionFilter.cpp, or 
just the client ? The problem I found was on the server-side; the client 
exception is just a downstream consequence of the server terminating the 
connection.

Can you attach to the server with a debugger, and see if any exceptions are 
being thrown?

Yes, I have rebuilt both client and server after updating 
OpenSslEncryptionFilter.cpp.
Server doesn't throw any exceptions while debugging, double checked this.
I only get the exception from the client while enabling thread pool on the 
server side.

thanks.

Yeah I've got the problem to reproduce in my environment as well... I'll post 
an update as soon as it's resolved.

OK - looks like there was a problem with the earlier fix to prevent excessive 
client-side recursion. It erroneously affected the server-side code path as 
well.

It should be fixed now. See how you go with the attached code... On my machine 
the sample SSL client and server (multithreaded) now run through without 
problems.
