Re-add the NetBSD CVS Id tag to the header. It just had to be quoted to
be accepted by the parser; i.e. no bug in the code :-)

Note to self: do not try to "fix" stuff the last minute before going to

Back out the change to introduce the X-NetBSD-Id header entry. For some
reason the parser does not accept its contents... You know, one should
always test even trivial changes!

Will review this in more depth tomorrow to find the real root cause of the
problem and rule out a fix for ATF.

[ozaki-r] Changes to the kernel core for wireguard

add ipsec(4) interface ATF.

branches: 1.33.2;
merge the bouyer-socketcan branch to HEAD.

CAN stands for Controller Area Network, a broadcast network used
in automation and automotive fields. For example, the NMEA2000 standard
developped for marine devices uses a CAN network as the link layer.

This is an implementation of the linux socketcan API:
https://www.kernel.org/doc/Documentation/networking/can.txt
you can also see can(4).

This adds a new socket family (AF_CAN) and protocol (PF_CAN),
as well as the canconfig(8) utility, used to set timing parameter of
CAN hardware. Also inclued is a driver for the CAN controller
found in the allwinner A20 SoC (I tested it with an Olimex lime2 board,
connected with PIC18-based CAN devices).

There is also the canloop(4) pseudo-device, which allows to use
the socketcan API without CAN hardware.

At this time the CANFD part of the linux socketcan API is not implemented.
Error frames are not implemented either. But I could get the cansend and
canreceive utilities from the canutils package to build and run with minimal
changes. tcpudmp(8) can also be used to record frames, which can be
decoded with etherreal.

tests: abort if MAC address duplication found

tests: dump stats of an interface before destroying it

tests: explain how rump_server_check_memleaks works

tests: restore rump_server_check_poolleaks for llentpl

It didn't work correctly because rumphijack for vmstat didn't work expectedly;
vmstat has the sgid bit for kvm(3) and that prevents rumphijack from working.

Address the issue by cloning a vmstat binary without the sgid bit temporarily
and using it for rumphijack. Note that it's a workaround. vmstat should stop
using kvm(3) for /dev/kmem and drop the sgid bit eventually.

Disable rump_server_check_memleaks for now

It doesn't work in some cases.

Currently only llentpl leaks can be detected.

Clean up the arp_rtm subtest...

1. Be assertive when claiming the pid of the background route monitor command,
not polite... (ie: $! will give you the pid, $? is just 0 there).
2. Since "wait 0" simply (always) exits with status 127, immediately (we
know without thinking that we have no child with pid 0) the waits were
ineffective - now (after fix #1) they work .. which requires the
route monitor that watches the arp -d to exit after 1 message, not 2,
as 1 is all it gets. (If there really should be 2, someone needs to
find out why the kernel is sending only 1 - I am not that someone).
3. The file contents need to be read only once, no matter how many patterns
we need to look for, save some work, and do it that way (this is not
really a bug,m but saving time for the ATF tests is always a good thing.)

Not sure if this will stop it randomly failing on bablyon5, but it might.
(The likely cause is that the "route.monitor" has not flushed its stdout
buffers at the time the "grep -A 3" [aside: why that way to read the file??]
is performed, so fails to find its expected output ... the route monitor would
get an extra message once interfaces start being destroyed, I assume, and
would exit then, flushing its buffer, but by then it is too late.
If that is/was the cause, then it should be fixed now.)

Enable to remove multiple ARP/NDP entries for one destination

The kernel can have multiple ARP/NDP entries which have an indentical
destination on different interfaces. This is normal and can be
reproduce easily by ping -I or ping6 -S. We should be able to remove
such entries.

arp -d <ip> and ndp -d <ip> are changed to fetch all ARP/NDP entries
and remove matched entries. So we can remove multiple entries
described above. This fetch all and selective removal behavior is
the same as arp <ip> and ndp <ip>; they also do fetch all entries
and show only matched entries.

Make a bunch of test names self-descriptive

Add a test case for static ARP

It tests receiving an ARP request that has a spa (i.e., IP address) whose
ARP entry already exists in the table as a static ARP entry.

Separate nexthop caches from the routing table

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

CAN stands for Controller Area Network, a broadcast network used
in automation and automotive fields. For example, the NMEA2000 standard
developped for marine devices uses a CAN network as the link layer.

This is an implementation of the linux socketcan API:
https://www.kernel.org/doc/Documentation/networking/can.txt
you can also see can(4).

This adds a new socket family (AF_CAN) and protocol (PF_CAN),
as well as the canconfig(8) utility, used to set timing parameter of
CAN hardware. Also inclued is a driver for the CAN controller
found in the allwinner A20 SoC (I tested it with an Olimex lime2 board,
connected with PIC18-based CAN devices).

There is also the canloop(4) pseudo-device, which allows to use
the socketcan API without CAN hardware.

At this time the CANFD part of the linux socketcan API is not implemented.
Error frames are not implemented either. But I could get the cansend and
canreceive utilities from the canutils package to build and run with minimal
changes. tcpudmp(8) can also be used to record frames, which can be
decoded with etherreal.

Put some sleeps between forking the hosts. Otherwise a race may

sending carp advertisements and ignore ping requests.

I'll get to the bottom of this eventually, but this is a stopgap
to prevent the test from failing, hopefully -- the race doesn't
appear to trigger for me even with 0.1s on a loaded machine, so
0.5s should be better than fine.

Add test case for PR kern/43548

Due to the nature of the feature under test, this one is a little
different, so let me explain how it works.

The test program forks and bootstraps a rump kernel in both processes.
It then configures shared memory interfaces in both. shmif is nice
in that it uses a mmaped file as the bus and does not require root
privileges for communication between two (or more) processes. The
child process then proceeds to increase icmp.returndatabytes as
indicated by the PR, while the parent process sets the global TTL
of the rump kernel to 1 (note: both values only affect the respective
rump kernels, not each other or more importantly the host kernel).
The parent then sends the bad packet which is supposed to be routed
by the child. If ip_icmp.c was too old, *boom* + fail; otherwise
nothing bad happens and the test exists with success after one
second.

Eventually this test can be extended into a framework for automated
testing of any networking code which requires (arbitrarily complex)
routing setups.

Separate nexthop caches from the routing table

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/.

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.

Add tests for ifconfig options

From s-yamaguchi@IIJ (with some tweaks by me)

Add tests of interface creation/destruction

Share rump_server start/stop and interface creation/destruction functions

The common functions store socks of rump_servers, interfaces of rump_servers
and buses that intefaces connect and allow to destroy them with common
functions without specifying which socks, interfaces and buses we should
destroy.

This change reduces lots of similar setup/cleanup codes.

Add $DEBUG and remove a unused function

Move get_macaddr to net_common.sh

+ -lrumpdev (and avoid doing stuff twice).

branches: 1.12.2;
Make a bunch of test names self-descriptive

Use rump.ping6 instead of ping6 with rumphijack(3)

Reflect a fix for bridge

Due to PR 48104, some tests of ping/ping6 were failed but the tests now
should be successful. So reverse atf_check.

Bonus: the fix for PR 48104 also fixes another uknown failure.

Add missing cleanup

Add tests for bridge members with an IP address

The tests include checks for PR#48104 which is not fixed yet.

Note that one test unexpectedly fails for some reason
(unrelated to PR#48104). We have to fix it somehow.

Disable test_ping_failure which is conducted before setup_bridge

It randomly fails (esp, often on a slow or loaded machine) due to
PR kern/49219, so disable it for now.

I forgot why I didn't include the test when I committed the test
at first and wrongly added it at v1.4.

Bump timeout for ping and ping6 to 5 sec

Hope the wait is enough for slow machines, e.g., qemu/anita/i386.

Get rid of unnecessary shebang

It will be added when it's built.

Enable IPv6 negative tests

As ping6 timeout feature (-X option) is added, we can do negative
tests without wasting time.

1 sec delay is added after network setup to avoid false positives.

Add tests for brconfig maxaddr

Add some tests for rtable operations of if_bridge

Add net/if_bridge test

fix various typos in documentation, comments and sysctl device description.
mainly aion -> ation and inlude -> include.

tests: use rump_server_add_iface to create interfaces

tests: check that a new cache is not created over the limit

Increase the timeout for the manyaddrs test case; the default is often
insufficient under qemu.

Make the lagg interface up before change its MTU

This change is related to PR kern/57650

branches: 1.8.2;
Add tests for MTU of lagg(4)

Added waiting for distributing state after attaching vlan

A lagg interface is reset on attaching vlan to enable
ETHERCAP_VLAN_MTU if the lagg I/F has it. Therefore,
it is necessary to wait for distributing.

Added tests for lagg(4) about MAC addresses

Added tests of combination of lagg(4), vlan(4), and l2tp(4)

Use IPv6 addresses, not IPv4, in combination test of IPv6, lagg and vlan

Centralize the base rump libraries into a variable used by all the other
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.

Deal with fallout from the addition of
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).

Get rid of all the -lrumpdev and -lrumpvfs that are no longer needed
after moving rump's mainbus from rumpdev to rumpkern.
