Remove routes on an address removal if the routes referencing to the address.  Implemented by ozaki-r@n.o.

A route that has a gateway is on a connected route can be invalid if the
connected route is deleted, i.e., an associated address is removed.
Traditionally NetBSD doesn't sweep such a route on the address removal.  Sending
packets over the route fails with "No route to host".  Also the route holds an
orphan ifaddr as rt_ifa that is destructed say by in_purgeaddr.

If the same address is assgined again in such a state, there can be two
different ifaddr objects with the same address.  Until recently it's not a
big problem because we can send packets anyway.  However after MP-ification
of the network stack, we can't send packets because we strictly check if rt_ifa
(i.e., the (old) ifaddr) is valid.

This change automatically removes such routes on a removal of an associated
address to avoid keeping inconsistent routes.

Add sysctl entry to control to send routing message for RTM_DYNAMIC.

Some routing daemons require such routing message to keep coherency.

If we want to let kernel send such message, set net.inet.icmp.dynamic_rt_msg=1
for IPv4, net.inet6.icmp6.dynamic_rt_msg=1 for IPv6.
Default(=0) is the same as before, that is, not send such routing message.

      If tunnel mode is specified, the sadb_x_ipsecrequest structure is

ipsecif(4) uses transport mode, so it should not add addresses.

Avoid having a rtcache directly in a percpu storage
percpu(9) has a certain memory storage for each CPU and provides it by the piece
to users.  If the storages went short, percpu(9) enlarges them by allocating new
larger memory areas, replacing old ones with them and destroying the old ones.
A percpu storage referenced by a pointer gotten via percpu_getref can be
destroyed by the mechanism after a running thread sleeps even if percpu_putref
has not been called.

Using rtcache, i.e., packet processing, typically involves sleepable operations
such as rwlock so we must avoid dereferencing a rtcache that is directly stored
in a percpu storage during packet processing.  Address this situation by having
just a pointer to a rtcache in a percpu storage instead.

For the rtsock compat code, make sure we create the "oroute" sysctl
tree.  Otherwise a 5.2 version of getifaddrs(2) gets errors.

This makes the 5.2 version of ifconfig(8) behave the same on both
NetBSD-8 and -current.  HOWEVER, both of them print nothing (for
``ifconfig -l'' command) so there's still a bug somewhere.

As reported originally by der Mouse.

Add the required hooks for rtsock_50 and modify the COMPATCALL() macro
to use the hooks.  While the rtsock_50 situation is still sub-optimal
(it includes the main rtsock.c with a whole bunch of function and
variable redefinitions via macros), this at least makes it possible to
load the rtsock_50 code separately from more recent code, rather than
the previous requirement that rtsock_50 be built-in.

Remove a wrong assertion in ifaref

 -

Doing ifref on an ifa with IFA_DESTROYING is not a problem; the reference should
be dropped during the destruction of the ifa.

 -

Use atomic operations for ifa_refcnt

 -

Avoid a dangling pointer during rt_replace_ifa

 -

Avoid double rt_replace_ifa on rtrequest1(RTM_ADD)

Some callers of rtrequest1(RTM_ADD) adjust rt_ifa of an rtentry created by
rtrequest1 that may change rt_ifa (in ifa_rtrequest) with another ifa that is
different from requested one.  It's wasteful and even worse introduces a race
condition.  rtrequest1 should just use a passed ifa as is if a caller hopes so.

 -

Use rt_update framework on updating a rtentry

Invalidate rtcache based on a global generation counter
The change introduces a global generation counter that is incremented when any
routes have been added or deleted. When a rtcache caches a rtentry into itself,
it also stores a snapshot of the generation counter. If the snapshot equals to
the global counter, the cache is still valid, otherwise invalidated.
One drawback of the change is that all rtcaches of all protocol families are
invalidated when any routes of any protocol families are added or deleted.
If that matters, we should have separate generation counters based on
protocol families.
This change removes LIST_ENTRY from struct route, which fixes a part of
PR kern/52515.
Remove the global lock for rtcache
Thanks to removal of LIST_ENTRY of struct route, rtcaches are accessed only by
their users. And in existing usages a rtcache is guranteed to be not accessed
simultaneously. So the rtcache framework doesn't need any exclusion controls
in itself.
Synchronize on rtcache_generation with rtlock

such entries.
arp -d <ip> and ndp -d <ip> are changed to fetch all ARP/NDP entries

Make the routing table and rtcaches MP-safe

See the following descriptions for details.

Proposed on tech-kern and tech-net


Overview
--------

We protect the routing table with a rwock and protect
rtcaches with another rwlock. Each rtentry is protected
from being freed or updated via reference counting and psref.

Global rwlocks
--------------

There are two rwlocks; one for the routing table (rt_lock) and
the other for rtcaches (rtcache_lock). rtcache_lock covers
all existing rtcaches; there may have room for optimizations
(future work).

The locking order is rtcache_lock first and rt_lock is next.

rtentry references
------------------

References to an rtentry is managed with reference counting
and psref. Either of the two mechanisms is used depending on
where a rtentry is obtained. Reference counting is used when
we obtain a rtentry from the routing table directly via
rtalloc1 and rtrequest{,1} while psref is used when we obtain
a rtentry from a rtcache via rtcache_* APIs. In both cases,
a caller can sleep/block with holding an obtained rtentry.

The reasons why we use two different mechanisms are (i) only
using reference counting hurts the performance due to atomic
instructions (rtcache case) (ii) ease of implementation;
applying psref to APIs such rtaloc1 and rtrequest{,1} requires
additional works (adding a local variable and an argument).

We will finally migrate to use only psref but we can do it
when we have a lockless routing table alternative.

Reference counting for rtentry
------------------------------

rt_refcnt now doesn't count permanent references such as for
rt_timers and rtcaches, instead it is used only for temporal
references when obtaining a rtentry via rtalloc1 and rtrequest{,1}.
We can do so because destroying a rtentry always involves
removing references of rt_timers and rtcaches to the rtentry
and we don't need to track such references. This also makes
it easy to wait for readers to release references on deleting
or updating a rtentry, i.e., we can simply wait until the
reference counter is 0 or 1. (If there are permanent references
the counter can be arbitrary.)

rt_ref increments a reference counter of a rtentry and rt_unref
decrements it. rt_ref is called inside APIs (rtalloc1 and
rtrequest{,1} so users don't need to care about it while
users must call rt_unref to an obtained rtentry after using it.

rtfree is removed and we use rt_unref and rt_free instead.
rt_unref now just decrements the counter of a given rtentry
and rt_free just tries to destroy a given rtentry.

See the next section for destructions of rtentries by rt_free.

Destructions of rtentries
-------------------------

We destroy a rtentry only when we call rtrequst{,1}(RTM_DELETE);
the original implementation can destroy in any rtfree where it's
the last reference. If we use reference counting or psref, it's
easy to understand if the place that a rtentry is destroyed is
fixed.

rt_free waits for references to a given rtentry to be released
before actually destroying the rtentry. rt_free uses a condition
variable (cv_wait) (and psref_target_destroy for psref) to wait.

Unfortunately rtrequst{,1}(RTM_DELETE) can be called in softint
that we cannot use cv_wait. In that case, we have to defer the
destruction to a workqueue.

rtentry#rt_cv, rtentry#rt_psref and global variables
(see rt_free_global) are added to conduct the procedure.

Updates of rtentries
--------------------

One difficulty to use refcnt/psref instead of rwlock for rtentry
is updates of rtentries. We need an additional mechanism to
prevent readers from seeing inconsistency of a rtentry being
updated.

We introduce RTF_UPDATING flag to rtentries that are updating.
While the flag is set to a rtentry, users cannot acquire the
rtentry. By doing so, we avoid users to see inconsistent
rtentries.

There are two options when a user tries to acquire a rtentry
with the RTF_UPDATING flag; if a user runs in softint context
the user fails to acquire a rtentry (NULL is returned).
Otherwise a user waits until the update completes by waiting
on cv.

The procedure of a updater is simpler to destruction of
a rtentry. Wait on cv (and psref) and after all readers left,
proceed with the update.

Global variables (see rt_update_global) are added to conduct
the procedure.

Currently we apply the mechanism to only RTM_CHANGE in
rtsock.c. We would have to apply other codes. See
"Known issues" section.

psref for rtentry
-----------------

When we obtain a rtentry from a rtcache via rtcache_* APIs,
psref is used to reference to the rtentry.

rtcache_ref acquires a reference to a rtentry with psref
and rtcache_unref releases the reference after using it.
rtcache_ref is called inside rtcache_* APIs and users don't
need to take care of it while users must call rtcache_unref
to release the reference.

struct psref and int bound that is needed for psref is
embedded into struct route. By doing so we don't need to
add local variables and additional argument to APIs.

However this adds another constraint to psref other than
reference counting one's; holding a reference of an rtentry
via a rtcache is allowed by just one caller at the same time.
So we must not acquire a rtentry via a rtcache twice and
avoid a recursive use of a rtcache. And also a rtcache must
be arranged to be used by a LWP/softint at the same time
somehow. For IP forwarding case, we have per-CPU rtcaches
used in softint so the constraint is guaranteed. For a h
rtcache of a PCB case, the constraint is guaranteed by the
solock of each PCB. Any other cases (pf, ipf, stf and ipsec)
are currently guaranteed by only the existence of the global
locks (softnet_lock and/or KERNEL_LOCK). If we've found the
cases that we cannot guarantee the constraint, we would need
to introduce other rtcache APIs that use simple reference
counting.

psref of rtcache is created with IPL_SOFTNET and so rtcache
shouldn't used at an IPL higher than IPL_SOFTNET.

Note that rtcache_free is used to invalidate a given rtcache.
We don't need another care by my change; just keep them as
they are.

Performance impact
------------------

When NET_MPSAFE is disabled the performance drop is 3% while
when it's enabled the drop is increased to 11%. The difference
comes from that currently we don't take any global locks and
don't use psref if NET_MPSAFE is disabled.

We can optimize the performance of the case of NET_MPSAFE
on by reducing lookups of rtcache that uses psref;
currently we do two lookups but we should be able to trim
one of two. This is a future work.

Known issues
------------

There are two known issues to be solved; one is that
a caller of rtrequest(RTM_ADD) may change rtentry (see rtinit).
We need to prevent new references during the update. Or
we may be able to remove the code (perhaps, need more
investigations).

The other is rtredirect that updates a rtentry. We need
to apply our update mechanism, however it's not easy because
rtredirect is called in softint and we cannot apply our
mechanism simply. One solution is to defer rtredirect to
a workqueue but it requires some code restructuring.

Add rtcache_unref to release points of rtentry stemming from rtcache

In the MP-safe world, a rtentry stemming from a rtcache can be freed at any
points. So we need to protect rtentries somehow say by reference couting or
passive references. Regardless of the method, we need to call some release
function of a rtentry after using it.

The change adds a new function rtcache_unref to release a rtentry. At this
point, this function does nothing because for now we don't add a reference
to a rtentry when we get one from a rtcache. We will add something useful
in a further commit.

This change is a part of changes for MP-safe routing table. It is separated
to avoid one big change that makes difficult to debug by bisecting.

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.

MP-safe by using pserialize and psref. At this moment, pserialize_perform
and psref_target_destroy are disabled because (1) we don't need them

Stop using rt_gwroute on packet sending paths

rt_gwroute of rtentry is a reference to a rtentry of the gateway
for a rtentry with RTF_GATEWAY. That was used by L2 (arp and ndp)
to look up L2 addresses. By separating L2 nexthop caches, we don't
need a route for the purpose and we can stop using rt_gwroute.
By doing so, we can reduce referencing and modifying rtentries,
which makes it easy to apply a lock (and/or psref) to the
routing table and rtentries.

One issue to do this is to keep RTF_REJECT behavior. It seems it
was broken when we moved rtalloc1 things from L2 output routines
(e.g., ether_output) to ip_hresolv_output, but (fortunately?)
it works unexpectedly. What we mistook are:
- RTF_REJECT was checked for any routes in L2 output routines,
  but in ip_hresolv_output it is checked only when the route
  is RTF_GATEWAY
- The RTF_REJECT check wasn't copied to IPv6 (nd6_output)

It seems that rt_gwroute checks hid the mistakes and it looked
work (unexpectedly) and removing rt_gwroute checks unveil the
issue. So we need to fix RTF_REJECT checks in ip_hresolv_output
and also add them to nd6_output.

One more point we have to care is returning an errno; we need
to mimic looutput behavior. Originally RTF_REJECT check was
done either in L2 output routines or in looutput. The latter is
applied when a reject route directs to a loopback interface.
However, now RTF_REJECT check is done before looutput so to keep
the original behavior we need to return an errno which looutput
chooses. Added rt_check_reject_route does such tweaks.

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

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.)

Add RTF_BROADCAST to mark routes used for the broadcast address when
they are created on the fly. This makes it clear what the route is for
and allows an optimisation in ip_output() by avoiding a call to
in_broadcast() because most of the time we do talk to a host.
It also avoids a needless allocation for the storage of llinfo_arp and
thus vanishes from arp(8) - it showed as incomplete anyway so this
is a nice side effect.

Guard against this and routes marked with RTF_BLACKHOLE in
ip_fastforward().
While here, guard against routes marked with RTF_BLACKHOLE in

RTF_BROADCAST is IPv4 only, so don't bother checking that here.

Move RTF_ANNOUNCE flag so that it no longer conflicts with RTF_PROTO2.

RTF_ANNOUNCE was defined as RTF_PROTO2.  The flag is used to indicated
that host should act as a proxy for a link level arp or ndp request.
(If RTF_PROTO2 is used as an experimental flag (as advertised),
various problems can occur.)

This commit provides a first-class definition with its own bit for
RTF_ANNOUNCE, removes the old aliasing definitions, and adds support
for the new RTF_ANNOUNCE flag to netstat(8) and route(8).,

Also, remove unused RTF_ flags that collide with RTF_PROTO1:
  netinet/icmp6.h defined RTF_PROBEMTU as RTF_PROTO1
  netinet/if_inarp.h defined RTF_USETRAILERS as RTF_PROTO1
  (Neither of these flags are used anywhere.  Both have been removed
  to reduce chances of collision with RTF_PROTO1.)

Figuring this out and the diff are the work of Beverly Schwartz of
BBN.

(Passed release build, boot in VM, with no apparently related atf
failures.)

Hide the radix-trie implementation of the forwarding table so that we
will have an easier time replacing it with something different, even if
it is a second radix-trie implementation.

sys/net/route.c and sys/net/rtsock.c no longer operate directly on
radix_nodes or radix_node_heads.

Hopefully this will reduce the temptation to implement multipath or
source-based routing using grotty hacks to the grotty old radix-trie
code, too. :-)

*** Summary ***

When a link-layer address changes (e.g., ifconfig ex0 link
02:de:ad:be:ef:02 active), send a gratuitous ARP and/or a Neighbor
Advertisement to update the network-/link-layer address bindings
on our LAN peers.

Refuse a change of ethernet address to the address 00:00:00:00:00:00
or to any multicast/broadcast address.  (Thanks matt@.)

Reorder ifnet ioctl operations so that driver ioctls may inherit
the functions of their "class"---ether_ioctl(), fddi_ioctl(), et
cetera---and the class ioctls may inherit from the generic ioctl,
ifioctl_common(), but both driver- and class-ioctls may override
the generic behavior.  Make network drivers share more code.

Distinguish a "factory" link-layer address from others for the
purposes of both protecting that address from deletion and computing
EUI64.

Return consistent, appropriate error codes from network drivers.

Improve readability.  KNF.

*** Details ***

In if_attach(), always initialize the interface ioctl routine,
ifnet->if_ioctl, if the driver has not already initialized it.
Delete if_ioctl == NULL tests everywhere else, because it cannot
happen.

In the ioctl routines of network interfaces, inherit common ioctl
behaviors by calling either ifioctl_common() or whichever ioctl
routine is appropriate for the class of interface---e.g., ether_ioctl()
for ethernets.

Stop (ab)using SIOCSIFADDR and start to use SIOCINITIFADDR.  In
the user->kernel interface, SIOCSIFADDR's argument was an ifreq,
but on the protocol->ifnet interface, SIOCSIFADDR's argument was
an ifaddr.  That was confusing, and it would work against me as I
make it possible for a network interface to overload most ioctls.
On the protocol->ifnet interface, replace SIOCSIFADDR with
SIOCINITIFADDR.  In ifioctl(), return EPERM if userland tries to
invoke SIOCINITIFADDR.

In ifioctl(), give the interface the first shot at handling most
interface ioctls, and give the protocol the second shot, instead
of the other way around. Finally, let compatibility code (COMPAT_OSOCK)
take a shot.

Pull device initialization out of switch statements under
SIOCINITIFADDR.  For example, pull ..._init() out of any switch
statement that looks like this:

        switch (...->sa_family) {
        case ...:
                ..._init();
                ...
                break;
        ...
        default:
                ..._init();
                ...
                break;
        }

Rewrite many if-else clauses that handle all permutations of IFF_UP
and IFF_RUNNING to use a switch statement,

        switch (x & (IFF_UP|IFF_RUNNING)) {
        case 0:
                ...
                break;
        case IFF_RUNNING:
                ...
                break;
        case IFF_UP:

        }

unifdef lots of code containing #ifdef FreeBSD, #ifdef NetBSD, and
#ifdef SIOCSIFMTU, especially in fwip(4) and in ndis(4).

In ipw(4), remove an if_set_sadl() call that is out of place.

In nfe(4), reuse the jumbo MTU logic in ether_ioctl().

Let ethernets register a callback for setting h/w state such as
promiscuous mode and the multicast filter in accord with a change
in the if_flags: ether_set_ifflags_cb() registers a callback that
returns ENETRESET if the caller should reset the ethernet by calling
if_init(), 0 on success, != 0 on failure.  Pull common code from
ex(4), gem(4), nfe(4), sip(4), tlp(4), vge(4) into ether_ioctl(),
and register if_flags callbacks for those drivers.

Return ENOTTY instead of EINVAL for inappropriate ioctls.  In
zyd(4), use ENXIO instead of ENOTTY to indicate that the device is
not any longer attached.

Add to if_set_sadl() a boolean 'factory' argument that indicates
whether a link-layer address was assigned by the factory or some
other source.  In a comment, recommend using the factory address
for generating an EUI64, and update in6_get_hw_ifid() to prefer a
factory address to any other link-layer address.

Add a routing message, RTM_LLINFO_UPD, that tells protocols to
update the binding of network-layer addresses to link-layer addresses.
Implement this message in IPv4 and IPv6 by sending a gratuitous
ARP or a neighbor advertisement, respectively.  Generate RTM_LLINFO_UPD
messages on a change of an interface's link-layer address.

In ether_ioctl(), do not let SIOCALIFADDR set a link-layer address
that is broadcast/multicast or equal to 00:00:00:00:00:00.

Make ether_ioctl() call ifioctl_common() to handle ioctls that it
does not understand.

In gif(4), initialize if_softc and use it, instead of assuming that
the gif_softc and ifp overlap.

Let ifioctl_common() handle SIOCGIFADDR.

Sprinkle rtcache_invariants(), which checks on DIAGNOSTIC kernels
that certain invariants on a struct route are satisfied.

In agr(4), rewrite agr_ioctl_filter() to be a bit more explicit
about the ioctls that we do not allow on an agr(4) member interface.

bzero -> memset.  Delete unnecessary casts to void *.  Use
sockaddr_in_init() and sockaddr_in6_init().  Compare pointers with
NULL instead of "testing truth".  Replace some instances of (type
*)0 with NULL.  Change some K&R prototypes to ANSI C, and join
lines.

Poison struct route->ro_rt uses in the kernel by changing the name

identifier/link-layer address.  Make code that treated the first

Remove stale debugging code from net/route.c.  Move the rtflush()

        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

        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.

Get rid of radix_node_head.rnh_walktree, because it is only ever
set to rn_walktree.

Introduce rt_walktree(), which applies a subroutine to every route
in a particular address family.  Use it instead of rn_walktree()
virtually everywhere.  This helps to hide the routing table
implementation.

Eliminate address family-specific route caches (struct route, struct
route_in6, struct route_iso), replacing all caches with a struct
route.

The principle benefit of this change is that all of the protocol
families can benefit from route cache-invalidation, which is
necessary for correct routing.  Route-cache invalidation fixes an
ancient PR, kern/3508, at long last; it fixes various other PRs,
also.

Discussions with and ideas from Joerg Sonnenberger influenced this
work tremendously.  Of course, all design oversights and bugs are
mine.

DETAILS

1 I added to each address family a pool of sockaddrs.  I have
  introduced routines for allocating, copying, and duplicating,
  and freeing sockaddrs:

        struct sockaddr *sockaddr_alloc(sa_family_t af, int flags);
        struct sockaddr *sockaddr_copy(struct sockaddr *dst,
                                       const struct sockaddr *src);
        struct sockaddr *sockaddr_dup(const struct sockaddr *src, int flags);
        void sockaddr_free(struct sockaddr *sa);

  sockaddr_alloc() returns either a sockaddr from the pool belonging
  to the specified family, or NULL if the pool is exhausted.  The
  returned sockaddr has the right size for that family; sa_family
  and sa_len fields are initialized to the family and sockaddr
  length---e.g., sa_family = AF_INET and sa_len = sizeof(struct
  sockaddr_in).  sockaddr_free() puts the given sockaddr back into
  its family's pool.

  sockaddr_dup() and sockaddr_copy() work analogously to strdup()
  and strcpy(), respectively.  sockaddr_copy() KASSERTs that the
  family of the destination and source sockaddrs are alike.

  The 'flags' argumet for sockaddr_alloc() and sockaddr_dup() is
  passed directly to pool_get(9).

2 I added routines for initializing sockaddrs in each address
  family, sockaddr_in_init(), sockaddr_in6_init(), sockaddr_iso_init(),
  etc.  They are fairly self-explanatory.

3 structs route_in6 and route_iso are no more.  All protocol families
  use struct route.  I have changed the route cache, 'struct route',
  so that it does not contain storage space for a sockaddr.  Instead,
  struct route points to a sockaddr coming from the pool the sockaddr
  belongs to.  I added a new method to struct route, rtcache_setdst(),
  for setting the cache destination:

        int rtcache_setdst(struct route *, const struct sockaddr *);

  rtcache_setdst() returns 0 on success, or ENOMEM if no memory is
  available to create the sockaddr storage.

  It is now possible for rtcache_getdst() to return NULL if, say,
  rtcache_setdst() failed.  I check the return value for NULL
  everywhere in the kernel.

4 Each routing domain (struct domain) has a list of live route
  caches, dom_rtcache.  rtflushall(sa_family_t af) looks up the
  domain indicated by 'af', walks the domain's list of route caches
  and invalidates each one.

KNF: de-__P, bzero -> memset, bcmp -> memcmp.  Remove extraneous
   parentheses in return statements.

Cosmetic: don't open-code TAILQ_FOREACH().

Cosmetic: change types of variables to avoid oodles of casts: in
   in6_src.c, avoid casts by changing several route_in6 pointers
   to struct route pointers.  Remove unnecessary casts to caddr_t
   elsewhere.

Pave the way for eliminating address family-specific route caches:
   soon, struct route will not embed a sockaddr, but it will hold
   a reference to an external sockaddr, instead.  We will set the
   destination sockaddr using rtcache_setdst().  (I created a stub
   for it, but it isn't used anywhere, yet.)  rtcache_free() will
   free the sockaddr.  I have extracted from rtcache_free() a helper
   subroutine, rtcache_clear().  rtcache_clear() will "forget" a
   cached route, but it will not forget the destination by releasing
   the sockaddr.  I use rtcache_clear() instead of rtcache_free()
   in rtcache_update(), because rtcache_update() is not supposed
   to forget the destination.

Constify:

   1 Introduce const accessor for route->ro_dst, rtcache_getdst().

   2 Constify the 'dst' argument to ifnet->if_output().  This
     led me to constify a lot of code called by output routines.

   3 Constify the sockaddr argument to protosw->pr_ctlinput.  This
     led me to constify a lot of code called by ctlinput routines.

   4 Introduce const macros for converting from a generic sockaddr
     to family-specific sockaddrs, e.g., sockaddr_in: satocsin6,
     satocsin, et cetera.

Introduce new helper functions to abstract the route caching.
rtcache_init and rtcache_init_noclone lookup ro_dst and store
the result in ro_rt, taking care of the reference counting and
calling the domain specific route cache.
rtcache_free checks if a route was cashed and frees the reference.
rtcache_copy copies ro_dst of the given struct route, checking that
enough space is available and incrementing the reference count of the
cached rtentry if necessary.
rtcache_check validates that the cached route is still up. If it isn't,
it tries to look it up again. Afterwards ro_rt is either a valid again
or NULL.
rtcache_copy is used internally.

Adjust to callers of rtalloc/rtflush in the tree to check the sanity of
ro_dst first (if necessary). If it doesn't fit the expectations, free
the cache, otherwise check if the cached route is still valid. After
that combination, a single check for ro_rt == NULL is enough to decide
whether a new lookup needs to be done with a different ro_dst.
Make the route checking in gre stricter by repeating the loop check
after revalidation.
Remove some unused RADIX_MPATH code in in6_src.c. The logic is slightly
changed here to first validate the route and check RTF_GATEWAY
afterwards. This is sementically equivalent though.
etherip doesn't need sc_route_expire similiar to the gif changes from
dyoung@ earlier.

Based on the earlier patch from dyoung@, reviewed and discussed with
him.

Here are various changes designed to protect against bad IPv4
routing caused by stale route caches (struct route).  Route caches
are sprinkled throughout PCBs, the IP fast-forwarding table, and
IP tunnel interfaces (gre, gif, stf).

Stale IPv6 and ISO route caches will be treated by separate patches.

Thank you to Christoph Badura for suggesting the general approach
to invalidating route caches that I take here.

Here are the details:

Add hooks to struct domain for tracking and for invalidating each
domain's route caches: dom_rtcache, dom_rtflush, and dom_rtflushall.

Introduce helper subroutines, rtflush(ro) for invalidating a route
cache, rtflushall(family) for invalidating all route caches in a
routing domain, and rtcache(ro) for notifying the domain of a new
cached route.

Chain together all IPv4 route caches where ro_rt != NULL.  Provide
in_rtcache() for adding a route to the chain.  Provide in_rtflush()
and in_rtflushall() for invalidating IPv4 route caches.  In
in_rtflush(), set ro_rt to NULL, and remove the route from the
chain.  In in_rtflushall(), walk the chain and remove every route
cache.

In rtrequest1(), call rtflushall() to invalidate route caches when
a route is added.

In gif(4), discard the workaround for stale caches that involves
expiring them every so often.

Replace the pattern 'RTFREE(ro->ro_rt); ro->ro_rt = NULL;' with a
call to rtflush(ro).

Update ipflow_fastforward() and all other users of route caches so
that they expect a cached route, ro->ro_rt, to turn to NULL.

Take care when moving a 'struct route' to rtflush() the source and
to rtcache() the destination.

In domain initializers, use .dom_xxx tags.

KNF here and there.

Add a source-address selection policy mechanism to the kernel.

Also, add ioctls SIOCGIFADDRPREF/SIOCSIFADDRPREF to get/set preference
numbers for addresses.  Make ifconfig(8) set/display preference
numbers.

To activate source-address selection policies in your kernel, add
'options IPSELSRC' to your kernel configuration.

Miscellaneous changes in support of source-address selection:

        1 Factor out some common code, producing rt_replace_ifa().

        2 Abbreviate a for-loop with TAILQ_FOREACH().

        3 Add the predicates on IPv4 addresses IN_LINKLOCAL() and
          IN_PRIVATE(), that are true for link-local unicast
          (169.254/16) and RFC1918 private addresses, respectively.
          Add the predicate IN_ANY_LOCAL() that is true for link-local
          unicast and multicast.

        4 Add IPv4-specific interface attach/detach routines,
          in_domifattach and in_domifdetach, which build #ifdef
          IPSELSRC.

See in_getifa(9) for a more thorough description of source-address
selection policy.

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it.  This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2 (UCB copyrighted).

have sys/net/route.c:rtrequest1(), which takes rt_addrinfo * as the argument.
pass rt_addrinfo all the way down to rtrequest, and ifa->ifa_rtrequest.
3rd arg of ifa->ifa_rtrequest is now rt_addrinfo * instead of sockaddr *
(almost noone is using it anyways).

benefit: the follwoing command now works.  previously we need two route(8)
invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0

remove unsafe typecast in rtrequest(), from rtentry * to sockaddr *.  it was
introduced by 4.3BSD-reno and never corrected.

XXX is eon_rtrequest() change correct regarding to 3rd arg?
eon_rtrequest() and rtrequest() were incorrect since 4.3BSD-reno,
so i do not have correct answer in the source code.
someone with more clue about netiso-over-ip, please help.

update icmp6 too big validation.  the change is necessary since pmtud is
mandatory for IPv6 (so we can't just validate by using connected pcb - we need
to allow traffic from unconnected pcb to do pmtud).

  route entries.
- if the traffic was not validated by xx_ctlinput, allow up to "lowat" pmtud
  route entries (there's upper limit, so bad guys cannot blow up our routing

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.
