* The header file netinet/in_var.h included netinet6/in6_var.h. Thisbluhm2013-10-171-2/+1
| | | | | | | created a bunch of useless dependencies. Remove this implicit inclusion and do an explicit #include <netinet6/in6_var.h> when it is needed. OK mpi@ henning@
* Don't send flows if flowsrc is not set. Packages had a brokenflorian2013-09-131-12/+20
| | | | | | | | | | checksum. Since no one seems to have a use case for sending flows from INADDR_ANY disallow this. Pointed out by Nathanael Rensen on tech@, thanks. While there make the SIOCSIFFLAGS and SIOCSETPFLOW cases symmetric by only sending templates if the interface is running. OK benno@

* netflow v10 omitted the sysUpTime flow set header field fromflorian2013-02-051-35/+90
| | | | | | | | | | | | v9. Without it it's not possible to find out at what time a flow started/ended with only flowStartSysUpTime/flowEndSysUpTime. Fix this by using flowStartSeconds/flowEndSeconds for v10. Problem reported by Chris Ivancic and Colin Ligertwood, analyzed by benno@ Tested by benno@ against nprobe (which doesn't care that much one way or the other) Tested by Chris Ivancic against solarwinds collector. OK benno@

| | | | | | | | | | | | | | | | runtime while time_uptime is monotonic. Prevent underflows in pfsync(4) and pflow(4) by using signed variables. pfsync(4) problem pointed out by camield. Diff originally by dlg, frag and pflow bits by me. feedback dlg man page tweak jmc Various versions of the pflow bits tested by Hrvoje Popovski (hrvoje AT srce DOT hr), thanks! ok benno, henning, dlg

| | | | | | sysctl.h was reliant on this particular include, and many drivers included sysctl.h unnecessarily. remove sysctl.h or add proc.h as needed. ok deraadt
