DTRACE_PRIV(4) Kernel Interfaces Manual DTRACE_PRIV(4) 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 DESCRIPTION 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 privi- lege check. The only argument to the priv probes, args[0], is the requested privilege number int priv. EXAMPLES Example 1: Tracing Kernel Privilege Check Failures 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(); } SEE ALSO dtrace(1), tracing(7), priv(9), SDT(9) AUTHORS The priv provider was written by Robert N.
