NAME

fsession, fauth - set up authentication on a file descriptor to a file server

SYNOPSIS


 

#include <u.h>

#include <libc.h>

#include <auth.h>


 


int   fsession(int fd, char trbuf[TICKREQLEN])


 


uchar fauth(int fd, char tbuf[2*TICKETLEN])

DESCRIPTION

The first time
fsession is called for the connection referred to by
fd, a
session (see
attach(5)) message is exchanged with the file server at
the other end of the connection.
Fsession uses the information returned by the file server and
the id of the user to build a ticket request message
returned in
trbuf. If the file server requires no authentication
or the kernel already has authentication tickets for the current user
for this connection,
trbuf[0] is set to 0.
If not,
trbuf can be used to obtain tickets from an authentication server.
Fsession should be called before any
mount (see
bind(2)) of
fd.

Fauth is used to pass authentication tickets to the kernel for the current
user.
The tickets are used to authenticate the user in any subsequent
mounts of
fd by that user.


It is rare to use these functions directly; more commonly
amount or
authenticate (see
auth(2)) is used.
