URL: <http://savannah.nongnu.org/bugs/?38066> Summary: Raw pcbs can alter packet without eating it Project: lwIP - A Lightweight TCP/IP stack Submitted by: goldsimon Submitted on: Fr 11 Jan 2013 20:56:29 GMT Category: IPv4 Severity: 3 - Normal Item Group: Faulty Behaviour Status: Confirmed Privacy: Public Assigned to: goldsimon Open/Closed: Open Discussion Lock: Any Planned Release: 1.5.0 lwIP version: 1.4.1 _______________________________________________________ Details: Reported by chrysn on lwip-users on 01-11-2013: The contrib ping app running in raw api mode prevents local ping-responses from working. The reason is that it alters the pbuf (by calling pbuf_header) when returning "not eaten". After that, the ping recv code in icmp.c fails. _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?38066> _______________________________________________ Nachricht gesendet von/durch Savannah http://savannah.nongnu.org/
