New Revision: 304544
URL: https://svnweb.freebsd.org/changeset/base/304544
Log:
Audit the accepted (or rejected) username argument to setlogin(2).
(NB: This was likely a mismerge from XNU in audit support, where the
text argument to setlogin(2) is captured -- but as a text token,
whereas this change uses the dedicated login-name field in struct
audit_record.)
