2022-11-09ndp, route, netstat: adjust ipv6 address widthKlemens Nanni
It has been annoying me for too long that fully specififed GUAs (2001:0db8:3333:4444:5555:6666:7777:8888) mess up alignment. systat(1)'s netstat is the only view that has a big enough limit and thus never misaligns. Unify ndp(8), route(8) and netstat(1) views to always align nicely. Feedback OK claudio
2022-06-19There is no reason to print the RTF_DONE bit in the routing table output.Claudio Jeker
It is now set on all routes (and before it was never set). OK tb@ anton@

OK claudio
2021-01-16Only recover the KAME embedded scope if the sin6_scope_id filed isClaudio Jeker
not initalized. If it is set assume that the scope was already recovered. This is required to get rid of all this scope madness in the long run. OK bluhm@ florian@

2020-09-15"Route show" and "netstat -r" provide formatting for routing tables withpamela
sufficient space to display v4 addresses cleanly, but which truncate v6 addresses. The -n flag on each already provides additional column width for IPv6 addresses. Make this formatting the default. OK phessler kn

2018-05-01Sync p_rttables() to netstat(1) version. Pointed out by claudio andFlorian Obser
mpi. Remaining differences are pledge and priority handling which only route(8) has. While here switch flushroutes to get_sysctl() function. OK benno
2018-04-30* simplify code by no longer calling getnetbyname(3)Ingo Schwarze
* avoid double lookups for unresolvable names without -net * more fitting error message for unresolvable names after -net OK florian@
2018-04-30tableid is either initialized to the current routing table or to theFlorian Obser
one specified by the T flag. No need to pass a flag around if the tableid is valid. It always is. This code is now in sync between flushroutes() and p_rttables(). OK benno, no objection claudio
2018-04-28Improve / simplify pledges.Florian Obser
1) after schwarze@'s rampage (thanks!) we can drop rpath since asr is no longer opening /etc/networks behind our back 2) we have the "route" pledge for the NET_RT_DUMP sysctl so we can pledge earlier in main; flushroutes() and p_rttables() now tighten the pledge instead of being the first pledge 3) the pledge in monitor() was just a repeat of the main() pledge, it can go.

2015-11-27After evaluating patches from Ricardo Mestre, it became obvious thatSebastian Benoit
route needs pledge("stdio rpath dns") in all cases. Looks best to me deraadt@
2015-10-23route has 3 code paths: monitor (listening on route socket); showTheo de Raadt
(sysctl and then print), change (getsocket, then read/write on that). Refactor lightly and insert pledge "stdio rpath dns" in each case. ok claudio benno phessler
2015-09-11Remove RTF_XRESOLVE support.Martin Pieuchot
2015-07-18On systems with a full routing table (550k+), we often want to be able toPeter Hessler
look at the routes with a priority, or to display all routes that do not have a specific priority (normally, don't show bgp). We are intentionally not updating netstat -r yet, as we do not have a good flag to use. first version from, and OK benno@

OK deraadt@
2015-01-16Replace <sys/param.h> with <limits.h> and other less dirty headers whereTheo de Raadt
possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)
2014-05-08Introduce two new route flags: RTF_LOCAL and RTF_BROADCAST.Martin Pieuchot
Nothing use them for the moment, but here is the plan: Since a route lookup is always necessary to output a packet it makes sense to store all the information regarding how the packet should be sent in the routing entry. This will save us some expensive lookups on address lists. But once we have all the information about our addresses in the routing table, we can even use it in the input path with the hope that the number of lookups in the forwarding case can be reduce to one. ok henning@, chris@

implied sizeof(struct rt_msghdr). Makes code more robust when userland and kernel are out of sync.
