    AREA/CLASS/EXAMPLE AFFECTED:

    ACE_SSL_SOCK_Acceptor


    DOES THE PROBLEM AFFECT:
        COMPILATION? No
        LINKING? No
            On Unix systems, did you run make realclean first?
        EXECUTION? Yes, application is affected
        OTHER (please specify)? No

    SYNOPSIS:

    Call to ACE_SSL_SOCK_Acceptor.accept fails for a listen

    Socket that has been passed in from another process.

    DESCRIPTION:
        Our application consists of a number of processes that accept TCP connections.
        At start-up 1 of the processes creates a listen socket.  Once it has accepted a
        certain number of connections it passes the socket to one of the other processes.
        The receiving process does a set_handle() call before waiting for new connections
        by calling accept().  This works fine when using ACE_SOCK_Acceptor class but when
        using ACE_SSL_SOCK_Acceptor the accept call fails.

    REPEAT BY:
         Ran application and connected a number of clients so that the "listen" socket
         would be passed to one of the other server application processes.

    SAMPLE FIX/WORKAROUND:
         Added a new routine to the ACE_SSL_SOCK_Acceptor.

// Allow the underlying ACE_SOCK_Acceptor handle to be set
// for receiving a passed listen socket

void
ACE_SSL_SOCK_Acceptor::set_handle_acceptor_ (ACE_HANDLE handle)
{
  ACE_TRACE ("ACE_SSL_SOCK_Acceptor::set_handle_acceptor_");

  this->acceptor_.set_handle (handle);
}

      Amended application to call the new routine after first calling
      The normal set_handle() method.

    AREA/CLASS/EXAMPLE AFFECTED:

    ACE_SSL_SOCK_Acceptor


    DOES THE PROBLEM AFFECT:
        COMPILATION? No
        LINKING? No
            On Unix systems, did you run make realclean first?
        EXECUTION? Yes, application and ACE is affected
        OTHER (please specify)? No

    SYNOPSIS:

    Call to ACE_SSL_SOCK_Acceptor.accept SEGVs when timeout specified

    and FD_SETSIZE exceeded.

    DESCRIPTION:
        Our application uses ACE_SSL_SOCK_Acceptor() class.  For SSL connections it calls
       ACE_SSL_SOCK_Acceptor.accept() with a timeout parameter.  It was being limited to
       FD_SETSIZE as the reactor is using select().  I added the following to the config.h
       file to have the reactor use epoll() instead of select().

#define ACE_USE_DEV_POLL_REACTOR_FOR_REACTOR_IMPL

       Testing showed we would get a SEGV when calling ACE_SSL_SOCK_Acceptor.accept()
       when specifying a timeout parameter and FD_SETSIZE was exceeded.

#10 0x000000000041c828 in main ()


    REPEAT BY:
         Ran application and connected a large number of clients

    SAMPLE FIX/WORKAROUND:
         The issue seems to be caused by ssl_accept() using ACE::select().  Replacing ACE::select() with ACE::handle_ready()
          as per the suggested fix in bug #3604<http://bugzilla.dre.vanderbilt.edu/show_bug.cgi?id=3604> resolves the issue.

Hi,

Thanks for using the PRF form, for the future I would recommend that you
include ace/config-linux.h in your ace/config.h file and refer to that
file without pasting its content

Could you extend one of the unit tests under ACE_wrappers/tests for this
and open a PR with the test extension and suggested fix on github at
https://github.com/DOCGroup/ACE_TAO, see
https://github.com/DOCGroup/ACE_TAO/pull/1044 for another PR which I
think is related.

Hi,

Thanks for using the PRF form, for the future I would recommend that you
include ace/config-linux.h in your ace/config.h file and refer to that
file without pasting its content

Could you extend one of the unit tests under ACE_wrappers/tests for this
and open a PR with the test extension and suggested fix on github at
https://github.com/DOCGroup/ACE_TAO.

>     Call to ACE_SSL_SOCK_Acceptor.accept SEGVs when timeout specified
>     and FD_SETSIZE exceeded.
>
>  
>
>     DESCRIPTION:
>
>         Our application uses ACE_SSL_SOCK_Acceptor() class.  For SSL
> connections it calls
>
>        ACE_SSL_SOCK_Acceptor.accept() with a timeout parameter.  It
> was being limited to
>
>        FD_SETSIZE as the reactor is using select().  I added the
> following to the config.h
>
>        file to have the reactor use epoll() instead of select().  
>
>  
>
> #define ACE_USE_DEV_POLL_REACTOR_FOR_REACTOR_IMPL
>
>  
>
>        Testing showed we would get a SEGV when calling
> ACE_SSL_SOCK_Acceptor.accept()
>
>        when specifying a timeout parameter and FD_SETSIZE was exceeded.

It definitely is related - it sounds like a very similar use case to the one that drove the earlier PR.

BTW, I forgot all about the PR, sorry - I just merged it and closed.

Hi,

Thanks for using the PRF form, for the future I would recommend that you include ace/config-linux.h in your ace/config.h file and refer to that file without pasting its content

Could you extend one of the unit tests under ACE_wrappers/tests for this and open a PR with the test extension and suggested fix on github at https://github.com/DOCGroup/ACE_TAO, see https://github.com/DOCGroup/ACE_TAO/pull/1044 for another PR which I think is related.

    AREA/CLASS/EXAMPLE AFFECTED:

    ACE_SSL_SOCK_Acceptor


    DOES THE PROBLEM AFFECT:
        COMPILATION? No
        LINKING? No
            On Unix systems, did you run make realclean first?
        EXECUTION? Yes, application and ACE is affected
        OTHER (please specify)? No

    SYNOPSIS:

    Call to ACE_SSL_SOCK_Acceptor.accept SEGVs when timeout specified

    and FD_SETSIZE exceeded.

    DESCRIPTION:
        Our application uses ACE_SSL_SOCK_Acceptor() class.  For SSL connections it calls
       ACE_SSL_SOCK_Acceptor.accept() with a timeout parameter.  It was being limited to
       FD_SETSIZE as the reactor is using select().  I added the following to the config.h
       file to have the reactor use epoll() instead of select().

#define ACE_USE_DEV_POLL_REACTOR_FOR_REACTOR_IMPL

       Testing showed we would get a SEGV when calling ACE_SSL_SOCK_Acceptor.accept()
       when specifying a timeout parameter and FD_SETSIZE was exceeded.

    REPEAT BY:
         Ran application and connected a large number of clients

    SAMPLE FIX/WORKAROUND:
         The issue seems to be caused by ssl_accept() using ACE::select().  Replacing ACE::select() with ACE::handle_ready()
          as per the suggested fix in bug #3604<http://bugzilla.dre.vanderbilt.edu/show_bug.cgi?id=3604> resolves the issue.
