frag6: don't use spin mutex for frag6_lock

frag6_lock is held during sending a packet (icmp6_error), so we must
not use a spin mutex because we can acquire sleep locks on sending
a packet.

Also we don't need to use spin mutex for frag6_lock anymore because
frag6_lock is now not used from hardware interrupt context.

When reassembling IPv4/IPv6 packets, ensure each fragment has been subject
to the same IPsec processing. That is to say, that all fragments are ESP,
or AH, or AH+ESP, or none.

The reassembly mechanism can be used both on the wire and inside an IPsec
tunnel, so we need to make sure all fragments of a packet were received
on only one side.

Even though I haven't tried, I believe there are configurations where it
would be possible for an attacker to inject an unencrypted fragment into a
legitimate stream of already-decrypted-and-authenticated fragments.

Typically on IPsec gateways with ESP tunnels, where we can encapsulate
fragments (as opposed to the general case, where we fragment encapsulated

Note, for the record: a funnier thing, under IPv4, would be to send a
zero-sized !MFF fragment at the head of the packet, and manage to trigger
an ICMP error; M_DECRYPTED gets lost by the reassembly, and ICMP will reply
with the packet in clear (not encrypted).

Remove M_PKTHDR from secondary mbufs when reassembling packets.

This is a real problem, because I found at least one component that relies
on the fact that only the first mbuf has M_PKTHDR: far from here, in
m_splithdr, we don't update m->m_pkthdr.len if M_PKTHDR is found in a
secondary mbuf. (The initial intention there was to avoid updating
m_pkthdr.len twice, the assumption was that if M_PKTHDR is set then we're
dealing with the first mbuf.) Therefore, when handling fragmented IPsec
packets (in particular IPv6, IPv4 is a bit more complicated), we may end
up with an incorrect m_pkthdr.len after authentication or decryption. In
the case of ESP, this can lead to a remote crash on this instruction:

	m_copydata(m, m->m_pkthdr.len - 3, 3, lastthree);

m_pkthdr.len is bigger than the actual mbuf chain.

It seems possible to me to trigger this bug even if you don't have the ESP
key, because the fragmentation part is outside of the encrypted ESP

So if you MITM the target, and intercept an incoming ESP packet (which you
can't decrypt), you should be able to forge a new specially-crafted,
fragmented packet and stuff the ESP payload (still encrypted, as you
intercepted it) into it. The decryption succeeds and the target crashes.

Fix a buffer overflow in ip6_get_prevhdr. Doing

	mtod(m, char *) + len

is wrong, an option is allowed to be located in another mbuf of the chain.
If the offset of an option within the chain is bigger than the length of
the first mbuf in that chain, we are reading/writing one byte of packet-
controlled data beyond the end of the first mbuf.

The length of this first mbuf depends on the layout the network driver
chose. In the most difficult case, it will allocate a 2KB cluster, which
is bigger than the Ethernet MTU.

But there is at least one way of exploiting this case: by sending a
special combination of nested IPv6 fragments, the packet can control a
good bunch of 'len'. By luck, the memory pool containing clusters does not
embed the pool header in front of the items, so it is not straightforward
to predict what is located at 'mtod(m, char *) + len'.

However, by sending offending fragments in a loop, it is possible to
crash the kernel - at some point we will hit important data structures.

As far as I can tell, PF protects against this difficult case, because
it kicks nested fragments. NPF does not protect against this. IPF I don't

Then there are the more easy cases, if the MTU is bigger than a cluster,
or if the network driver did not allocate a cluster, or perhaps if the
fragments are received via a tunnel; I haven't investigated these cases.

Change ip6_get_prevhdr so that it returns an offset in the chain, and
always use IP6_EXTHDR_GET to get a writable pointer. IP6_EXTHDR_GET
leaves M_PKTHDR untouched.

This place is still fragile.

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.

Loganaden Velvindron:

From "":

A host that receives an IPv6 packet which includes a Fragment
Header with the "Fragment Offset" equal to 0 and the "M" bit equal
to 0 MUST process such packet in isolation from any other packets/
fragments, even if such packets/fragments contain the same set
{IPV6 Source Address, IPv6 Destination Address, Fragment
Identification}.  That is, the Fragment Header of "atomic
fragments" should be removed by the receiving host, and the
resulting packet should be processed as a non-fragmented IPv6
datagram.  Additionally, any fragments already queued with the
same set {IPV6 Source Address, IPv6 Destination Address, Fragment
Identification} should not be discarded upon receipt of the
"colliding" IPv6 atomic fragment, since IPv6 atomic fragments do
not really interfere with "normal" fragmented traffic.

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

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,

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


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

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.


   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.

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

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.

remove extra portability #ifdef (like #ifdef __FreeBSD__) in KAME IPv6/IPsec
code, from netbsd-current repository.
#ifdef'ed version is always available from

XXX please do not make too many diff-unfriendly changes, we'll need to take
bunch of diffs on upgrade...

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.

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

(sorry for jumbo commit, I can't separate this any more...)

fix IPv6 fragment ID initialization - random() does not return
random value when frag6_init() is called, so use microtime() to stir
the value better.

s/splnet/splsoftnet/ in IPv6/IPsec part.
hope I made no mistake (the kernel works fine but I need a regress test)

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 (
- 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.
