Synopsis: free NULL mbuf in function icmp_errer() State-Changed-From-To: open->feedback State-Changed-By: iedowse State-Changed-When: Thu Jun 20 06:44:01 PDT 2002 State-Changed-Why: I think you have misread the code. The mbuf chain 'n' being freed is not the same as the one 'm' that is tested for NULL. Also, if you look at the code for m_freem() you will see that it is safe to call it with a NULL argument anyway (icmp_error calls m_freem(), not m_free() at the freeit label). Can you confirm that you just misread the code so that this problem report can be closed? If you have seen a panic that you believe was caused by a bug here, please post a stack trace. http://www.freebsd.org/cgi/query-pr.cgi?pr=39571 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
