SSL enable give/takedescriptor API's

The give/takedescriptor API's allow one to exchange the socket between a listener (main) program and a submitted client job.

This however only works for non-SSL connections which makes it impossible to use the concept for accepting multiple simultaneous clients.

Please provide a method for transferring the SSL state of the socket to a client job.

    We are happy to see you were able to split the secure handshake processing into the 2nd process, by passing the connection first, and then securing it in the 2nd process. Since there is an alternate working design and IBM does not intend to provide a give/takedescriptor solution, the request is being closed.

    The CEAC has reviewed this requirement and recommends that IBM view this as a MEDIUM priority requirement that should be addressed.

    Background: The COMMON Europe Advisory Council (CEAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CEAC has a crucial role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community and has therefore reviewed your RFE.

    I can confirm that the "split the accept/upgrade process" works. The SSL logic is now transferred from the "listener" job to the submitted "client" job.

    A side note is however that the "listener" job is not aware that the "client" job might fail due to an incorrect SSL negotiation (so far I don't know if there are other implications of this split logic).

    I'm currently evaluating the "split the accept/upgrade process" but still have a few issues.

    I'll report back in this RFE once I have more information if this is a viable solution.

    Thank you for providing the additional information. IBM understands the requirement and will evaluate it as part of the plan process. A response will be provided after evaluation is complete.

    The CAAC has reviewed this requirement and recommends that IBM view this as a medium priority requirement that should be addressed. Although there are viable work-arounds, this request is one of the more worthwhile to implement.

    Hi,

    The application originates from a "single" connection where the accepted socket was upgraded to an SSL socket and being used to communicate with the client in SSL mode. By upgrading the program to a "multiple client" version the socket logic was kept together, after which the socket was passed to the client. I could try to split the accept/upgrade process between the listener program and the actual server program as you seem to suggest.

    The new process runs under the same userprofile by default however this isn't a strict requirement (however authority shouldn't be a problem). If the same userprofile is however a requirement, it should be no problem to respect this requirement.

    Yes, the GSKit API's are used, ie. gsk_secure_soc_open, gsk_attribute_set_numeric_value, gsk_secure_soc_init.

    Hello Paul,
    Thank you for taking the time to submit this request. We would like to get some more information to further understand and assess your Request for Enhancement.

    Why does the application server pass the secure connection between processes? Can the server process accept the new TCP connection and pass the connection to have the client process establish the secure connection rather than pass the connection after the secure session is established? Does the new process run under the same user profile as the server process listening for connections or what authority does the profile have for the giving and taking processes? Does your application use the GSKit APIs to establish the secure connection?
