Security Token Transport -

Token routines using fread and fwrite.

Token Get File Descriptor

 
int globus_gss_assist_token_get_fd (void *arg, void **bufp, size_t *sizep)

Token Send File Descriptor

 
int globus_gss_assist_token_send_fd (void *arg, void *buf, size_t size)

Token Send File Descriptor Without Length

 
int globus_gss_assist_token_send_fd_without_length (void *arg, void *buf, size_t size)

Token Send File Descriptor Flag EX

 
int globus_gss_assist_token_send_fd_ex (void *exp, void *buf, size_t size)

Detailed Description

Token routines using fread and fwrite.

Additional code has been added to detect tokens which are sent without a length field. These can currently be only SSL tokens. This does require some knowledge of the underlying GSSAPI, by the application, but is within the guidelines of the GSSAPI specifications.

The get routine will automaticly attempt this test, while a new send routine will check a flag. The old send routine will work as before, sending a 4-byte length.

Function Documentation

int globus_gss_assist_token_get_fd (void * arg, void ** bufp, size_t * sizep)

Use a open file discriptor to get a token. This function provides parameter types that allow it to be passed to globus_gss_assist_init_sec_context and globus_gss_assist_accept_sec_context

Parameters:

arg the FILE * stream cast to a void pointer
bufp the resulting token
sizep the size (number of bytes) read into bufp

Returns:

0 on success > 0 is internal return < 0 is the -errno

int globus_gss_assist_token_send_fd (void * arg, void * buf, size_t size)

Write a token to the open file descriptor. WIll write it with a 4 byte length. This function provides parameter types that allow it to be passed to globus_gss_assist_init_sec_context and globus_gss_assist_accept_sec_context

Parameters:

arg the FILE * stream to send the token on
buf the token
size the size of the token in bytes

Returns:

0 on success >0 on error <0 on errno error

int globus_gss_assist_token_send_fd_without_length (void * arg, void * buf, size_t size)

Write a token to the open file descripter. Will write it without a length. so as to

int globus_gss_assist_token_send_fd_ex (void * exp, void * buf, size_t size)

Write a token to the open file descripter. will look at the flag to determine if the length field need to be written.

Parameters:

exp the globus_gss_assist_ex variable that holds the FILE * stream and flags to bet set
buf the token buffer to send
size size of the token buffer

Returns:

0 on success >0 on error <0 on errno error (-errno)
