NAME

au_user_mask- Get user's binary preselection mask

SYNOPSIS

cc [flags...] 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.

SUMMARY OF TRUSTED SOLARIS CHANGES

By default, auditing is enabled in the Trusted Solaris environment. Trusted Solaris 2.5.1, 7, and later releases extend the number of audit classes and audit events, and introduce new but similar structures and programming interfaces.

NOTES

This functionality is active only if auditing has been enabled. au_user_mask() should be called by programs like login(1) that set the preselection mask of a process with setaudit(2) in the Trusted Solaris 8 Reference Manual. getaudit(2) should be used to obtain audit characteristics for the current process.
