selinux_set_callback - userspace SELinux callback facilities
#include <selinux/selinux.h>
void selinux_set_callback(int type, union selinux_callback callback);
selinux_set_callback() sets the callback indicated by type to the
value of callback, which should be passed as a function pointer cast
to type union selinux_callback.
All callback functions should return a negative value with errno set
appropriately on error.
The available values for type are:
SELINUX_CB_LOG
int (*func_log) (int type, const char *fmt, ...);
This callback is used for logging and should process the
printf(3) style fmt string and arguments as appropriate. The
type argument indicates the type of message and will be set to
one of the following:
SELINUX_ERROR
SELINUX_WARNING
SELINUX_INFO
SELINUX_AVC
SELINUX_CB_AUDIT
int (*func_audit) (void *auditdata, security_class_t cls,
char *msgbuf, size_t msgbufsize);
This callback is used for supplemental auditing in AVC
messages. The auditdata and cls arguments are the values
passed to avc_has_perm(3). A human-readable interpretation
should be printed to msgbuf using no more than msgbufsize
characters.
SELINUX_CB_VALIDATE
int (*func_validate) (char **ctx);
This callback is used for context validation. The callback
may optionally modify the input context by setting the target
of the ctx pointer to a new context. In this case, the old
value should be freed with freecon(3). The value of errno
should be set to EINVAL to indicate an invalid context.
SELINUX_CB_SETENFORCE
int (*func_setenforce) (int enforcing);
This callback is invoked when the system enforcing state
changes. The enforcing argument indicates the new value and
is set to 1 for enforcing mode, and 0 for permissive mode.
SELINUX_CB_POLICYLOAD
int (*func_policyload) (int seqno);
This callback is invoked when the system security policy is
reloaded. The seqno argument is the current sequential number
of the policy generation in the system.
None.
None.
