Makefiles so that we can make changes to it centrally as needed and have
less mess. Fixes the sun2 build that needs rumpvfs after librump after
the latest changes.
KERN_PROC_CWD in sysctl(3)
That is kern.proc.$$.KERN_PROC_CWD (I think - not that it matters here)
The effect is that -lrump now requires -lrumpvfs
This set of changes fixes (I believe) regular dynamic builds,
more might be required for static builds (will be verified soon).
I don't know if <if_index> is expected to be accepted instead of
an interface name. Please update the test case if the behavior is
just a bug and ifconfig gets fixed.
To this end, carpattach needs to be delayed from RUMP_COMPONENT_NET to
RUMP_COMPONENT_NET_IF on rump_server. Otherwise mutex_enter via carpattach
for if_clone_mtx is called before mutex_init for it in ifinit1.
By this change, nexthop caches (IP-MAC address pair) are not stored
in the routing table anymore. Instead nexthop caches are stored in
each network interface; we already have lltable/llentry data structure
for this purpose. This change also obsoletes the concept of cloning/cloned
routes. Cloned routes no longer exist while cloning routes still exist
with renamed to connected routes.
Noticeable changes are:
- Nexthop caches aren't listed in route show/netstat -r
- sysctl(NET_RT_DUMP) doesn't return them
- If RTF_LLDATA is specified, it returns nexthop caches
- Several definitions of routing flags and messages are removed
- RTF_CLONING, RTF_XRESOLVE, RTF_LLINFO, RTF_CLONED and RTM_RESOLVE
- RTF_CONNECTED is added
- It has the same value of RTF_CLONING for backward compatibility
- route's -xresolve, -[no]cloned and -llinfo options are removed
- -[no]cloning remains because it seems there are users
- -[no]connected is introduced and recommended
to be used instead of -[no]cloning
- route show/netstat -r drops some flags
- 'L' and 'c' are not seen anymore
- 'C' now indicates a connected route
- Gateway value of a route of an interface address is now not
a L2 address but "link#N" like a connected (cloning) route
- Proxy ARP: "arp -s ... pub" doesn't create a route
You can know details of behavior changes by seeing diffs under tests/.
Proposed on tech-net and tech-kern:
http://mail-index.netbsd.org/tech-net/2016/03/11/msg005701.html
ifconfig -a -v after ifconfig -a -z is expected to show '0 packets' for
all interface. However, shmif0 can receive packets between the two
operations. So we have to keep shmif0 down during such tests.
