Remove in-kernel handling of Router Advertisements

This is much better handled by a user-land tool.
Proposed on tech-net here:
https://mail-index.netbsd.org/tech-net/2020/04/22/msg007766.html

Note that the ioctl SIOCGIFINFO_IN6 no longer sets flags. That now
needs to be done using the pre-existing SIOCSIFINFO_FLAGS ioctl.

Compat is fully provided where it makes sense, but trying to turn on
RA handling will obviously throw an error as it no longer exists.

Note that if you use IPv6 temporary addresses, this now needs to be
turned on in dhcpcd.conf(5) rather than in sysctl.conf(5).

Fix default route selection

The primary issue was that in revision 1.79 a check was added in the
nd6_defrouter_select() search loop to ignore the entry if RA processing
is enabled on its interface.  In practice this results in all entries
being ignored.

This fix reverses the condition, so that an entry is ignored when RA
processing is NOT enabled on its interface.  Further, the entry is
only ignored for being selected as the default router.  The currently
installed router must be identified regardless of the (current) status
of its interface, so that we can delete the route before installing a
new one.

I also added error logging when adding or deleting a route fails. This
should help the administrator (or kernel developer) in noticing possible
problems.

Finally, if deleting a route fails, the corresponding default route
entry no longer has its "installed" flag cleared, so that deletion will
be retried.  At a minimum, this will cause repeated messages about the
failed deletion as opposed to only getting repeated messages about the
installation of a new default route failing.

Fixes PR kern/55091 and also PR bin/54997 as far as the behaviour
observed with ndp(8).

Protect IPv6 default router and prefix lists with coarse-grained rwlock

in6_purgeaddr (in6_unlink_ifa) itself unrefernces a prefix entry and calls
nd6_prelist_remove if the counter becomes 0, so callers doesn't need to
handle the reference counting.

Performance-sensitive paths (sending/forwarding packets) call just one
reader lock. This is a trade-off between performance impact vs. the amount
of efforts; if we want to remove the reader lock, we need huge amount of
works including destroying objects with psz/psref in softint, for example.

Don't use rt_walktree to delete routes

Some functions use rt_walktree to scan the routing table and delete
matched routes. However, we shouldn't use rt_walktree to delete
routes because rt_walktree is recursive to the routing table (radix
tree) and isn't friendly to MP-ification. rt_walktree allows a caller
to pass a callback function to delete an matched entry. The callback
function is called from an API of the radix tree (rn_walktree) but
also calls an API of the radix tree to delete an entry.

This change adds a new API of the radix tree, rn_search_matched,
which returns a matched entry that is selected by a callback
function passed by a caller and the caller itself deletes the
entry. By using the API, we can avoid the recursive form.

Separate ioctl address prefix management from RA prefix management
as we have no API for controlling the latter.

This fixes a long standing problem where addresses added with non /128
prefixes and non infinte address lifetimes would register a prefix route
which would expire. Subsequent calls set new lifetimes for the same address
would not affect the prefix route management, so once expired, the
prefix route would be impossible to add back as the kernel would remove it.

Avoid storing a pointer of an interface in a mbuf

Having a pointer of an interface in a mbuf isn't safe if we remove big
kernel locks; an interface object (ifnet) can be destroyed anytime in any
packet processing and accessing such object via a pointer is racy. Instead
we have to get an object from the interface collection (ifindex2ifnet) via
an interface index (if_index) that is stored to a mbuf instead of an
pointer.

The change provides two APIs: m_{get,put}_rcvif_psref that use psref(9)
for sleep-able critical sections and m_{get,put}_rcvif that use
pserialize(9) for other critical sections. The change also adds another
API called m_get_rcvif_NOMPSAFE, that is NOT MP-safe and for transition
moratorium, i.e., it is intended to be used for places where are not
planned to be MP-ified soon.

The change adds some overhead due to psref to performance sensitive paths,
however the overhead is not serious, 2% down at worst.

Proposed on tech-kern and tech-net.

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/.

Use lltable/llentry for NDP

lltable and llentry were introduced to replace ARP cache data structure
for further restructuring of the routing table: L2 nexthop cache
separation. This change replaces the NDP cache data structure
(llinfo_nd6) with them as well as ARP.

One noticeable change is for neighbor cache GC mechanism that was
introduced to prevent IPv6 DoS attacks. net.inet6.ip6.neighborgcthresh
was the max number of caches that we store in the system. After
introducing lltable/llentry, the value is changed to be per-interface
basis because lltable/llentry stores neighbor caches in each interface
separately. And the change brings one degradation; the old GC mechanism
dropped exceeded packets based on LRU while the new implementation drops
packets in order from the beginning of lltable (a hash table + linked
lists). It would be improved in the future.

Added functions in in6.c come from FreeBSD (as of r286629) and are
tweaked for NetBSD.

Proposed on tech-kern and tech-net.

Use time_uptime instead of time_second to avoid time leaps

Some codes in sys/net* use time_second to manage time periods such as
cache expirations. However, time_second doesn't increase monotonically
and can leap by say settimeofday(2) according to time_second(9). We
should use time_uptime instead of it to avoid such time leaps.

This change replaces time_second with time_uptime. Additionally it
converts a time based on time_uptime to a time based on time_second
when the kernel passes the time to userland programs that expect
the latter, and vice versa.

Note that we shouldn't leak time_uptime to other hosts over the
netowrk. My investigation shows there is no such leak:

Reform use of rt_refcnt

rt_refcnt of rtentry was used in bad manners, for example, direct rt_refcnt++
and rt_refcnt-- outside route.c, "rt->rt_refcnt++; rtfree(rt);" idiom, and
touching rt after rt->rt_refcnt--.

These abuses seem to be needed because rt_refcnt manages only references
between rtentry and doesn't take care of references during packet processing
(IOW references from local variables). In order to reduce the above abuses,
the latter cases should be counted by rt_refcnt as well as the former cases.

This change improves consistency of use of rt_refcnt:
- rtentry is always accessed with rt_refcnt incremented
- rtentry's rt_refcnt is decremented after use (rtfree is always used instead
  of rt_refcnt--)
- functions returning rtentry increment its rt_refcnt (and caller rtfree it)

Note that rt_refcnt prevents rtentry from being freed but doesn't prevent
rtentry from being updated. Toward MP-safe, we need to provide another
protection for rtentry, e.g., locks. (Or introduce a better data structure
allowing concurrent readers during updates.)

When an interface link state changes to down, mark all attached IPv6
addresses as detached.
Likewise, when the link state changes to up, mark all detached IPv6

Advertised router reachability now checks that link state is not down.
This means that when an interface link state changes, the default IPv6

indeed have resulted in an uninitialised variable use. Yay gcc 4.1.

First step of random number subsystem rework described in
<20111022023242.BA26F14A158@mail.netbsd.org>.  This change includes
the following:

	An initial cleanup and minor reorganization of the entropy pool
	code in sys/dev/rnd.c and sys/dev/rndpool.c.  Several bugs are
	fixed.  Some effort is made to accumulate entropy more quickly at
	boot time.

	A generic interface, "rndsink", is added, for stream generators to
	request that they be re-keyed with good quality entropy from the pool
	as soon as it is available.

	The arc4random()/arc4randbytes() implementation in libkern is
	adjusted to use the rndsink interface for rekeying, which helps
	address the problem of low-quality keys at boot time.

	An implementation of the FIPS 140-2 statistical tests for random
	number generator quality is provided (libkern/rngtest.c).  This
	is based on Greg Rose's implementation from Qualcomm.

	A new random stream generator, nist_ctr_drbg, is provided.  It is
	based on an implementation of the NIST SP800-90 CTR_DRBG by
	Henric Jungheim.  This generator users AES in a modified counter
	mode to generate a backtracking-resistant random stream.

	An abstraction layer, "cprng", is provided for in-kernel consumers
	of randomness.  The arc4random/arc4randbytes API is deprecated for
	in-kernel use.  It is replaced by "cprng_strong".  The current
	cprng_fast implementation wraps the existing arc4random
	implementation.  The current cprng_strong implementation wraps the
	new CTR_DRBG implementation.  Both interfaces are rekeyed from
	the entropy pool automatically at intervals justifiable from best
	current cryptographic practice.

	In some quick tests, cprng_fast() is about the same speed as
	the old arc4randbytes(), and cprng_strong() is about 20% faster
	than rnd_extract_data().  Performance is expected to improve.

	The AES code in src/crypto/rijndael is no longer an optional
	kernel component, as it is required by cprng_strong, which is
	not an optional kernel component.

	The entropy pool output is subjected to the rngtest tests at
	startup time; if it fails, the system will reboot.  There is
	approximately a 3/10000 chance of a false positive from these
	tests.  Entropy pool _input_ from hardware random numbers is
	subjected to the rngtest tests at attach time, as well as the
	FIPS continuous-output test, to detect bad or stuck hardware
	RNGs; if any are detected, they are detached, but the system
	continues to run.

	A problem with rndctl(8) is fixed -- datastructures with
	pointers in arrays are no longer passed to userspace (this
	was not a security problem, but rather a major issue for
	compat32).  A new kernel will require a new rndctl.

	The sysctl kern.arandom() and kern.urandom() nodes are hooked
	up to the new generators, but the /dev/*random pseudodevices
	are not, yet.

	Manual pages for the new kernel interfaces are forthcoming.

RA flood mitigation via a limit on accepted routes:
- introduce a limit for the routes accepted via IPv6 Router Advertisement:
  a common 2 interface client will have 6, the default limit is 100 and
  can be adjusted via sysctl
- report the current number of routes installed via RA via sysctl
- count discarded route additions. Note that one RA message is two routes.
  This is at present only across all interfaces even though per-interface
  would be more useful, since the per-interface structure complies to RFC2466
- bump kernel version due to the previous change
- adjust netstat to use the new value (with netstat -p icmp6)

Fix net.inet6.ip6.accept_rtadv and 'ndp -i <interface> accept_rtadv':

Add a flag ND6_IFF_OVERRIDE_RTADV that tells the kernel to override
ip6_accept_rtadv (net.inet6.ip6.accept_rtadv) on an interface.

Add a routine nd6_accepts_rtadv(ndi) that evaluates both the flags
on the interface represented by ndi and ip6_accept_rtadv, and
returns 'true' if the given interface should accept Router
Advertisements, and 'false' if not.

Now, ND6_IFF_ACCEPT_RTADV works as it was historically documented:
if it is set, then accept router advertisements iff ip6_accept_rtadv
!= 0.  Otherwise, do not accept router advertisements.

If ND6_IFF_OVERRIDE_RTADV is set, then the flag ND6_IFF_ACCEPT_RTADV
overrides ip6_accept_rtadv: if ND6_IFF_ACCEPT_RTADV is set, accept;
otherwise reject.  Ignore ip6_accept_rtadv.

If neither ND6_IFF_ACCEPT_RTADV nor ND6_IFF_OVERRIDE_RTADV is set,
reject Router Advertisements.

Poison struct route->ro_rt uses in the kernel by changing the name
to _ro_rt.  Use rtcache_getrt() to access a route cache's struct
rtentry *.

Introduce struct ifnet->if_dl that always points at the interface
identifier/link-layer address.  Make code that treated the first
ifaddr on struct ifnet->if_addrlist as the interface address use
if_dl, instead.

Remove stale debugging code from net/route.c.  Move the rtflush()
code into rtcache_clear() and delete rtflush().  Delete rtalloc(),
because nothing uses it any more.

Make ND6_HINT an inline, lowercase subroutine, nd6_hint.

I've done my best to convert IP Filter, the ISO stack, and the
AppleTalk stack to rtcache_getrt().  They compile, but I have not
tested them.  I have given the changes to PF, GRE, IPv4 and IPv6
stacks a lot of exercise.

Take steps to hide the radix_node implementation of the forwarding table
from the forwarding table's users:

        Introduce rt_walktree() for walking the routing table and
        applying a function to each rtentry.  Replace most
        rn_walktree() calls with it.

        Use rt_getkey()/rt_setkey() to get/set a route's destination.
        Keep a pointer to the sockaddr key in the rtentry, so that
        rtentry users do not have to grovel in the radix_node for
        the key.

        Add a RTM_GET method to rtrequest.  Use that instead of
        radix_node lookups in, e.g., carp(4).

Add sys/net/link_proto.c, which supplies sockaddr routines for
link-layer socket addresses (sockaddr_dl).

Cosmetic:

        Constify.  KNF.  Stop open-coding LIST_FOREACH, TAILQ_FOREACH,
        et cetera.  Use NULL instead of 0 for null pointers.  Use
        __arraycount().  Reduce gratuitous parenthesization.

        Stop using variadic arguments for rip6_output(), it is
        unnecessary.

        Remove the unnecessary rtentry member rt_genmask and the
        code to maintain it, since nothing actually used it.

        Make rt_maskedcopy() easier to read by using meaningful variable
        names.

        Extract a subroutine intern_netmask() for looking up a netmask in
        the masks table.

        Start converting backslash-ridden IPv6 macros in
        sys/netinet6/in6_var.h into inline subroutines that one
        can read without special eyeglasses.

One functional change: when the kernel serves an RTM_GET, RTM_LOCK,
or RTM_CHANGE request, it applies the netmask (if supplied) to a
destination before searching for it in the forwarding table.

I have changed sys/netinet/ip_carp.c, carp_setroute(), to remove
the unlawful radix_node knowledge.

Apart from the changes to carp(4), netiso, ATM, and strip(4), I
have run the changes on three nodes in my wireless routing testbed,
which involves IPv4 + IPv6 dynamic routing acrobatics, and it's
working beautifully so far.

RFC 4191 changed the meaning of the "Reserved" Router Preference
value. Previously the router should treat the recieved router
advertisement as having a 0 router lifetime. The RFC now says that the
router should treat the "Reserved" field the same way as if it was the
medium (default) preference.

NDP-related improvements:
        RFC4191
	- supports host-side router-preference

	RFC3542
	- if DAD fails on a interface, disables IPv6 operation on the
          interface
	- don't advertise MLD report before DAD finishes

	Others
	- fixes integer overflow for valid and preferred lifetimes
	- improves timer granularity for MLD, using callout-timer.
	- reflects rtadvd's IPv6 host variable information into kernel
	  (router only)
	- adds a sysctl option to enable/disable pMTUd for multicast
          packets
	- performs NUD on PPP/GRE interface by default
	- Redirect works regardless of ip6_accept_rtadv
	- removes RFC1885-related code

Better support of IPv6 scoped addresses.

- most of the kernel code will not care about the actual encoding of
  scope zone IDs and won't touch "s6_addr16[1]" directly.
- similarly, most of the kernel code will not care about link-local
  scoped addresses as a special case.
- scope boundary check will be stricter.  For example, the current
  *BSD code allows a packet with src=::1 and dst=(some global IPv6
  address) to be sent outside of the node, if the application do:
    s = socket(AF_INET6);
    bind(s, "::1");
    sendto(s, some_global_IPv6_addr);
  This is clearly wrong, since ::1 is only meaningful within a single
  node, but the current implementation of the *BSD kernel cannot
  reject this attempt.
- and, while there, don't try to remove the ff02::/32 interface route
  entry in in6_ifdetach() as it's already gone.

This also includes some level of support for the standard source
address selection algorithm defined in RFC3484, which will be
completed on in the future.

First-draft if_detach() implementation, originally from Bill Studnemund,
although this version has been changed somewhat:
- reference counting on ifaddrs isn't as complete as Bill's original
  work was.  This is hard to get right, and we should attack one
  protocol at a time.
- This doesn't do reference counting or dynamic allocation of ifnets yet.
- This version introduces a new PRU -- PRU_PURGEADDR, which is used to
  purge an ifaddr from a protocol.  The old method Bill used didn't work
  on all protocols, and it only worked on some because it was Very Lucky.

This mostly works ... i.e. works for my USB Ethernet, except for a dangling
ifaddr reference left by the IPv6 code; have not yet tracked this down.

sync IPv6 part with latest KAME tree.   IPsec part is left unmodified
due to massive changes in KAME side.
- IPv6 output goes through nd6_output
- faith can capture IPv4 packets as well - you can run IPv4-to-IPv6 translator
  using heavily modified DNS servers
- per-interface statistics (required for IPv6 MIB)
- interface autoconfig is revisited
- udp input handling has a big change for mapped address support.
- introduce in4_cksum() for non-overwriting checksumming
- introduce m_pulldown()
- neighbor discovery cleanups/improvements
- netinet/in.h strictly conforms to RFC2553 (no extra defs visible to userland)
- IFA_STATS is fixed a bit (not tested)
- and more more more.

TODO:
- cleanup os-independency #ifdef
- avoid rcvif dual use (for IPsec) to help ifdetach

IPv6 kernel code, based on KAME/NetBSD 1.4, SNAP kit 19990628.
(Sorry for a big commit, I can't separate this into several pieces...)
Pls check sys/netinet6/TODO and sys/netinet6/IMPLEMENTATION for details.

- sys/kern: do not assume single mbuf, accept chained mbuf on passing
  data from userland to kernel (or other way round).
- "midway" ATM card: ATM PVC pseudo device support, like those done in ALTQ
  package (ftp://ftp.csl.sony.co.jp/pub/kjc/).
- sys/netinet/tcp*: IPv4/v6 dual stack tcp support.
- sys/netinet/{ip6,icmp6}.h, sys/net/pfkeyv2.h: IETF document assumes those
  file to be there so we patch it up.
- sys/netinet: IPsec additions are here and there.
- sys/netinet6/*: most of IPv6 code sits here.
- sys/netkey: IPsec key management code
- dev/pci/pcidevs: regen

In my understanding no code here is subject to export control so it
should be safe.
