NAME

dtrace_priv — a DTrace provider for the kernel privilege checking API

SYNOPSIS

priv:kernel:priv_check:priv-ok

priv:kernel:priv_check:priv-err

The priv provider allows for tracing the priv(9) API.

The priv:kernel:priv_check:priv-ok probe fires upon a successful kernel privilege check.

The priv:kernel:priv_check:priv-err probe fires upon a failed kernel privilege check.

The only argument to the priv probes, args[0], is the requested privilege number int priv.

The following script captures an array of counters, one for each stack trace leading to a failed kernel privilege check:

priv:::priv-err
{
	@traces[stack()] = count();
}

The priv provider was written by Robert N. M. Watson <rwatson@FreeBSD.org>.
