Detailed Description
Globus XIO GSI Driver.
Opening/Closing
An XIO handle with the gsi driver can be created with either globus_xio_handle_create ()
or globus_xio_server_register_accept ().
If the handle is created with globus_xio_server_register_accept (), the
globus_xio_register_open () call will proceed to accept a GSSAPI security context. Upon
successful completion of the open (after the open callback has been called) the
application may proceed to read or write data associated with the GSI session.
If the handle is created with globus_xio_handle_create (), then the XIO handle will
implement the client-side (init) of the GSSAPI call sequence and establish a security
context with the accepting side indicated by the contact_string passed to
globus_xio_register_open ().
Reading/Writing
The GSI driver behaves similar to the underlying transport driver with respect to reads
and writes, except for the try-read and try-write operations (ie. waitforbytes ==0) which
always return immediately. This is due to the fact that the security layer needs to read
and write tokens of a certain minimal size and thus needs to rely on the underlying
transport to handle greater than 0 reads/write which is not possible in 'try' mode.
Server
globus_xio_server_create() causes a new transport-specific listener socket to be created
to handle new GSI connections. globus_xio_server_register_accept() will accept a new
connection for processing. globus_xio_server_register_close() cleans up the internal
resources associated with the http server and calls close on the listener.
All accepted handles inherit all GSI-specific attributes set in the attr to
globus_xio_server_create(), but can be overridden with the attr to
globus_xio_register_open(). Furthermore, accepted handles will use the GSSAPI accept
security context call unless explicitly overridden during the globus_xio_register_open()
call ( GLOBUS_XIO_GSI_FORCE_SERVER_MODE).
Environment Variables
The gsi driver uses the following environment variables
• X509_USER_PROXY
• X509_USER_CERT
• X509_USER_KEY
• X509_CERT_DIR
For details see Globus: GSI Environment Variables

Error Types
The GSI driver uses mostly GSSAPI calls, so it generally just wraps the underlying GSSAPI
errors or uses generic XIO errors.
