Servers

The following security attribute fields of the SVCXPRT structure can be accessed directly by the server process:

t6attr_t xp_tsol_incoming_attrsp
t6attr_t xp_tsol_outgoing_attrsp
t6mask_t xp_tsol_incoming_new_attrs

A server can receive one or more security attributes of incoming client requests by using t6alloc_blk(3NSL) to allocate an opaque structure with space for the security attributes and setting xp_tsol_incoming_attrsp field in the SVCXPRT structure to point to the security attribute structure.

A privileged server can set security attributes on a request to the server by using t6alloc_blk(3NSL) to allocate an opaque structure with space for the security attributes and setting xp_tsol_outgoing_attrsp field in the SVCXPRT to point to the security attribute structure. The RPC library routines pick up the attributes and send them as the attributes for the response.

A server can examine the security attributes on the next and last bytes of data by using the xp_tsol_incoming_new_attrs field in the SVCXPRT structure to point to specific incoming attributes to be examined.
