pam_sm_open_session, pam_sm_close_session - Service provider implemen‐
tation for pam_open_session and pam_close_session respectively
SYNOPSIS
cc [ flag ... ] file ... -lpam [ library ... ]
#include <security/pam_appl.h>
#include <security/pam_modules.h>
int pam_sm_open_session(pam_handle_t *pamh, int flags, int argc, const
char **argv);
int pam_sm_close_session(pam_handle_t *pamh, int flags, int argc, const
char **argv);
DESCRIPTION
In response to a call to pam_open_session(3) and pam_close_session(3),
the PAM framework calls pam_sm_open_session() and pam_sm_close_ses‐
sion(), respectively from the modules listed in the pam.conf(4) file.
The session management provider supplies the back-end functionality for
this interface function.
pam_sm_open_session() is called to initiate session management.
pam_sm_close_session() is invoked when a session has terminated. The
argument pamh is an authentication handle. The following flag may be
set in the flags field:
PAM_SILENT Session service should not generate any messages
The argc argument represents the number of scheme options passed in
from the configuration file pam.conf(4). argv specifies the scheme
options, which are interpreted and processed by the session management
service. If an unknown option is passed in, an error should be logged
through syslog(3) and the option ignored.
RETURN VALUES
Upon successful completion, PAM_SUCCESS should be returned. The fol‐
lowing values may also be returned upon error:
PAM_SESSION_ERR Can not make/remove an entry for the spec‐
ified session
PAM_IGNORE Ignore underlying session module regard‐
less of whether the control flag is
required, optional or sufficient
