Thanks. ------- Forwarded message follows ------- Date sent: Fri, 25 Jan 2002 23:35:38 +0000 From: Bruce M Simpson <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: ip_output() does not checksum outer header Dan, if you could forward this on to freebsd-net I would be most grateful. I have completed most of the code to implement GRE as a regular interface driver under 4.4-STABLE using the cloner interface. This has all worked fine in local tests. Tonight, whilst testing with a remote site, we noticed that the encapsulating IP datagram header around the GRE header does not have any header checksum. I have checked, checked and re-checked the m->m_len, m->m_pkthdr.len, m_pullup() results et al and can find nothing out of the ordinary. This is driving me mad right now, can anybody shed any light on the problem? Regards, Bruce. ------- End of forwarded message ------- -- Dan Langille The FreeBSD Diary - http://freebsddiary.org/ - practical examples To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
