Because .Vt mac_t is a complex structure in the .Tn TrustedBSD implementation, .Fn mac_free is specific to -.Vt mac_3 , +.Vt mac_t , and must not be used to free the character strings returned from .Fn mac_to_text . Doing so may result in undefined behavior. diff --git a/lib/libc/posix1e/mac_text.3 b/lib/libc/posix1e/mac_text.3 index 29c1aacca485..7633f4b0da64 100644 --- a/lib/libc/posix1e/mac_text.3 +++ b/lib/libc/posix1e/mac_text.3 @@ -1,109 +1,111 @@ .\" Copyright (c) 2001 Networks Associates Technology, Inc. .\" All rights reserved. .\" .\" This software was developed for the FreeBSD Project by Chris .\" Costello at Safeport Network Services and NAI Labs, the Security .\" Research Division of Network Associates, Inc. under DARPA/SPAWAR .\" contract N66001-01-C-8035 ("CBOSS"), as part of the DARPA CHATS .\" research program. .\" .\" Redistribution and use in source and binary forms, with or without .\" modification, are permitted provided that the following conditions .\" are met: .\" 1.
