Maximum Data Size

Two functions -- rpc_gss_max_data_length() and rpc_gss_svc_max_data_length() -- are useful in determining how large a piece of data can be before it is transformed by security measures and sent "over the wire." That is, a security transformation such as encryption usually changes the size of a piece of transmitted data (most often enlarging it). To make sure that data won't be enlarged past a usable size, these two functions -- the former is the client-side version, the latter the server-side -- return the maximum pre-transformation size for a given transport.

For more information, see the rpc_gss_max_data_length(3N) and rpc_gss_svc_max_data_length(3N) man pages.
