NAME

au_user_mask- get user's binary preselection mask

SYNOPSIS

cc [ flag ... ] file ... -lbsm -lsocket -lnsl -lintl [ library ... ]
#include <bsm/libbsm.h>

int au_user_mask(char *username, au_mask_t *mask_p);

DESCRIPTION

au_user_mask() reads the default, system wide audit classes from audit_control(4), combines them with the per-user audit classes from the audit_user(4) database, and updates the binary preselection mask pointed to by mask_p with the combined value.

The audit flags in the flags field of the audit_control(4) database and the always-audit-flags and never-audit-flags from the audit_user(4) database represent binary audit classes. These fields are combined by au_preselect(3BSM) as follows:

---

mask = ( flags + always-audit-flags) - never-audit-flags

---

au_user_mask() only fails if both the both the audit_control(4) and the audit_user(4) database entries could not be retrieved. This allows for flexible configurations.

RETURN VALUES

au_user_mask() returns:

0

Success.

-1

Failure. Both the audit_control(4) and the audit_user(4) database entries could not be retrieved.

FILES

/etc/security/audit_control

contains default parameters read by the audit daemon, auditd(1M)

/etc/security/audit_user

stores per-user audit event mask

NOTES

au_user_mask() should be called by programs like login(1) which set a process's preselection mask with setaudit(2). getaudit(2) should be used to obtain audit characteristics for the current process.

The functionality described in this man page is available only if the Basic Security Module (BSM) has been enabled. See bsmconv(1M) for more information.
