https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=288680 Bug ID: 288680 Summary: netstat delivered count can be corrupt (negative) Product: Base System Version: 13.5-STABLE Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: mibelanger@qnx.com The following illustrates the issue: # netstat -s -p udp udp: 1 datagram received 0 with incomplete header 0 with bad data length field 0 with bad checksum 0 with no checksum 1 dropped due to no socket 1 broadcast/multicast datagram undelivered 0 dropped due to full socket buffers 0 not for hashed pcb 18446744073709551615 delivered 0 datagrams output 0 times multicast source filter matched The delivered count is calculated here: https://github.com/freebsd/freebsd-src/blob/releng/13.5/usr.bin/netstat/inet.c#L938 The "udps_noport" count already includes the "udps_noportbcast" count. The "duplicate" subtraction corrupts the "delivered" count. -- You are receiving this mail because: You are the assignee for the bug.home | help
