      Update the SSL_set_bio()/SSL_set0_rbio()/SSL_set0_wbio() docs · e040a42e
      Matt Caswell authored
      
      
      Update the documentation for the newly renamed and modified SSL_set0_rbio()
      and SSL_set0_wbio() functions. State that they should be preferred over
      SSL_set_bio(). Attempt to document the ownership rules for SSL_set_bio().

      Simplify and rename SSL_set_rbio() and SSL_set_wbio() · 65e2d672
      Matt Caswell authored
      SSL_set_rbio() and SSL_set_wbio() are new functions in 1.1.0 and really
      should be called SSL_set0_rbio() and SSL_set0_wbio(). The old
      implementation was not consistent with what "set0" means though as there
      were special cases around what happens if the rbio and wbio are the same.
      We were only ever taking one reference on the BIO, and checking everywhere
      whether the rbio and wbio are the same so as not to double free.
      
      A better approach is to rename the functions to SSL_set0_rbio() and
      SSL_set0_wbio(). If an existing BIO is present it is *always* freed
      regardless of whether the rbio and wbio are the same or not. It is
      therefore the callers responsibility to ensure that a reference is taken
      for *each* usage, i.e. one for the rbio and one for the wbio.
      
      The legacy function SSL_set_bio() takes both the rbio and wbio in one go
      and sets them both. We can wrap up the old behaviour in the implementation
      of that function, i.e. previously if the rbio and wbio ar...

      Add some SSL BIO tests · 9a716987
      Matt Caswell authored
      
      
      This adds some simple SSL BIO tests that check for pushing and popping of
      BIOs into the chain. These tests would have caught the bugs fixed in the
      previous three commits, if combined with a crypto-mdebug build.

      Fix BIO_pop for SSL BIOs · b46fe860
      Matt Caswell authored
      
      
      The BIO_pop implementation assumes that the rbio still equals the next BIO
      in the chain. While this would normally be the case, it is possible that it
      could have been changed directly by the application. It also does not
      properly cater for the scenario where the buffering BIO is still in place
      for the write BIO.
      
      Most of the existing BIO_pop code for SSL BIOs can be replaced by a single
      call to SSL_set_bio(). This is equivalent to the existing code but
      additionally handles the scenario where the rbio has been changed or the
      buffering BIO is still in place.
