Remove the IN6_IS_ADDR_V4MAPPED checks in the protocol functions. They
are useless, because the IPv6 entry point (ip6_input) already performs
them.

The checks were first added in the protocol functions:

	Wed Dec 22 04:03:02 1999 UTC (18 years, 1 month ago) by itojun

"drop IPv6 packets with v4 mapped address on src/dst.  they are illegal
and may be used to fool IPv6 implementations (by using ::ffff:127.0.0.1 as
source you may be able to pretend the packet is from local node)"

Shortly afterwards they were also added in the IPv6 entry point, but
where not removed from the protocol functions:

	Mon Jan 31 10:33:22 2000 UTC (18 years ago) by itojun

"be proactive about malicious packet on the wire.  we fear that v4 mapped
address to be used as a tool to hose security filters (like bypassing
"local host only" filter by using ::ffff:127.0.0.1)."

OpenBSD did the same a few months ago. FreeBSD has never had these checks.

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
know.

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.

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

fix: "ifconfig destory" can stalls when "ifconfig" is done parallel.
This problem occurs only if NET_MPSAFE on.

ifconfig destroy side:
    kernel entry point is ifioctl => if_clone_destroy.
    pr_purgeif() acquires softnet_lock, and then ifa_remove() calls
    pserialize_perform() holding softnet_lock.
ifconfig side:
    kernel entry point is socreate.
    pr_attach()(udp_attach_wrapper()) calls sosetlock(). In this call path,
    sosetlock() try to acquire softnet_lock.
These can cause dead lock.

This change makes struct ifaddr and its variants (in_ifaddr and in6_ifaddr)
MP-safe by using pserialize and psref. At this moment, pserialize_perform

So we'll enable them when we remove softnet_lock in the future.

Make sure returning ifp from in6_select* functions psref-ed

To this end, callers need to pass struct psref to the functions
and the fuctions acquire a reference of ifp with it. In some cases,
we can simply use if_get_byindex, however, in other cases
(say rt->rt_ifp and ia->ifa_ifp), we have no MP-safe way for now.
In order to take a reference anyway we use non MP-safe function
if_acquire_NOMPSAFE for the latter cases. They should be fixed in
the future somehow.

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.

Protect ifnet list with psz and psref

The change ensures that ifnet objects in the ifnet list aren't freed during

Note that the change adds a pslist(9) for ifnet but doesn't remove the
original ifnet list (ifnet_list) to avoid breaking kvm(3) users. We
shouldn't use the original list in the kernel anymore.

Patch posted to tech-net@
  http://mail-index.netbsd.org/tech-net/2015/03/15/msg005004.html

The choice to use a new structure sockaddr_big has been retained since
changing sockaddr_storage size would lead to unnecessary ABI change. The
use of the new structure does not preclude future work that increases
the size of sockaddr_storage and at that time sockaddr_big may be
trivially replaced.

backout change that made pr_stat return EOPNOTSUPP for protocols that
were not filling in struct stat.

decision made after further discussion with rmind and investigation of
how other operating systems behave.  soo_stat() is doing just enough to
be able to call what gets returned valid and thus justifys a return of
success.

additional review will be done to determine of the pr_stat functions
that were already returning EOPNOTSUPP can be considered successful with
what soo_stat() is doing.

Reduces the resources demanded by TCP sessions in TIME_WAIT-state using
methods called Vestigial Time-Wait (VTW) and Maximum Segment Lifetime
Truncation (MSLT).

MSLT and VTW were contributed by Coyote Point Systems, Inc.

Even after a TCP session enters the TIME_WAIT state, its corresponding
socket and protocol control blocks (PCBs) stick around until the TCP
Maximum Segment Lifetime (MSL) expires.  On a host whose workload
necessarily creates and closes down many TCP sockets, the sockets & PCBs
for TCP sessions in TIME_WAIT state amount to many megabytes of dead
weight in RAM.

Maximum Segment Lifetimes Truncation (MSLT) assigns each TCP session to
a class based on the nearness of the peer.  Corresponding to each class
is an MSL, and a session uses the MSL of its class.  The classes are
loopback (local host equals remote host), local (local host and remote
host are on the same link/subnet), and remote (local host and remote
host communicate via one or more gateways).  Classes corresponding to
nearer peers have lower MSLs by default: 2 seconds for loopback, 10
seconds for local, 60 seconds for remote.  Loopback and local sessions
expire more quickly when MSLT is used.

Vestigial Time-Wait (VTW) replaces a TIME_WAIT session's PCB/socket
dead weight with a compact representation of the session, called a
"vestigial PCB".  VTW data structures are designed to be very fast and
memory-efficient: for fast insertion and lookup of vestigial PCBs,
the PCBs are stored in a hash table that is designed to minimize the
number of cacheline visits per lookup/insertion.  The memory both
for vestigial PCBs and for elements of the PCB hashtable come from
fixed-size pools, and linked data structures exploit this to conserve
memory by representing references with a narrow index/offset from the
start of a pool instead of a pointer.  When space for new vestigial PCBs
runs out, VTW makes room by discarding old vestigial PCBs, oldest first.
VTW cooperates with MSLT.

It may help to think of VTW as a "FIN cache" by analogy to the SYN
cache.

A 2.8-GHz Pentium 4 running a test workload that creates TIME_WAIT
sessions as fast as it can is approximately 17% idle when VTW is active
versus 0% idle when VTW is inactive.  It has 103 megabytes more free RAM
when VTW is active (approximately 64k vestigial PCBs are created) than
when it is inactive.

1) Introduce a new socket option, (SOL_SOCKET, SO_NOHEADER), that
   tells a socket that it should both add a protocol header to tx'd
   datagrams and remove the header from rx'd datagrams:

        int onoff = 1, s = socket(...);
        setsockopt(s, SOL_SOCKET, SO_NOHEADER, &onoff);

2) Add an implementation of (SOL_SOCKET, SO_NOHEADER) for raw IPv4
   sockets.

3) Reorganize the protocols' pr_ctloutput implementations a bit.
   Consistently return ENOPROTOOPT when an option is unsupported,
   and EINVAL if a supported option's arguments are incorrect.
   Reorganize the flow of code so that it's more clear how/when
   options are passed down the stack until they are handled.

   Shorten some pr_ctloutput staircases for readability.

4) Extract common mbuf code into subroutines, add new sockaddr
   methods, and introduce a new subroutine, fsocreate(), for reuse
   later; use it first in sys_socket():

struct mbuf *m_getsombuf(struct socket *so)

        Create an mbuf and make its owner the socket `so'.

struct mbuf *m_intopt(struct socket *so, int val)

        Create an mbuf, make its owner the socket `so', put the
        int `val' into it, and set its length to sizeof(int).


int fsocreate(..., int *fd)

        Create a socket, a la socreate(9), put the socket into the
        given LWP's descriptor table, return the descriptor at `fd'
        on success.

void *sockaddr_addr(struct sockaddr *sa, socklen_t *slenp)
const void *sockaddr_const_addr(const struct sockaddr *sa, socklen_t *slenp)

        Extract a pointer to the address part of a sockaddr.  Write
        the length of the address  part at `slenp', if `slenp' is
        not NULL.

socklen_t sockaddr_getlen(const struct sockaddr *sa)

        Return the length of a sockaddr.  This just evaluates to
        sa->sa_len.  I only add this for consistency with code that
        appears in a portable userland library that I am going to
        import.

const struct sockaddr *sockaddr_any(const struct sockaddr *sa)

        Return the "don't care" sockaddr in the same family as
        `sa'.  This is the address a client should sobind(9) if it
        does not care the source address and, if applicable, the
        port et cetera that it uses.

const void *sockaddr_anyaddr(const struct sockaddr *sa, socklen_t *slenp)

        Return the "don't care" sockaddr in the same family as
        `sa'.  This is the address a client should sobind(9) if it
        does not care the source address and, if applicable, the

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.

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.

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.

disallow bind(2) with IPv4 mapped address for now.  port number check is
insufficient at this moment and we can bind(2) two sockets listen on same
port number.

for real fix, we need to check inpcb table with in6pcb.  we can't
find inpcb chain from particular in6pcb chain (like finding tcbtable from tcb6)
luckily RFC2553 does not talk about bind(2) behavior for IPv4 mapped.
IPv4 mapped brings in too much complexities...

introduce m->m_pkthdr.aux to hold random data which needs to be passed
between protocol handlers.

ipsec socket pointers, ipsec decryption/auth information, tunnel
decapsulation information are in my mind - there can be several other usage.
at this moment, we use this for ipsec socket pointer passing.  this will
avoid reuse of m->m_pkthdr.rcvif in ipsec code.

due to the change, MHLEN will be decreased by sizeof(void *) - for example,
for i386, MHLEN was 100 bytes, but is now 96 bytes.
we may want to increase MSIZE from 128 to 256 for some of our architectures.

take caution if you use it for keeping some data item for long period
of time - use extra caution on M_PREPEND() or m_adj(), as they may result
in loss of m->m_pkthdr.aux pointer (and mbuf leak).

this will bump kernel version.

(as discussed in tech-net, tested in kame tree)

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.

- Call in{,6}_pcbdetach if ipsec initialization is failed during PRU_ATTACH.
  This situation happens on severe memory shortage.  We may need more
  improvements here and there.
- Grab IEEE802 address from IFT_ETHER card, even if the card is
  inserted after bootup time.  Is there any other card that can be
  inserted afterwards?  pcmcia fddi card? :-P
- RFC2373 u bit handling suggests that we SHOULD NOT copy interface id from
  ethernet card to pseudo interface, when ethernet card has IEEE802/EUI64
  with u bit != 0 (this means that IEEE802/EUI64 is not universally unique).
  Do not use such address as, for example, interface id for gif interface.
  (I have such an ethernet card myself)
  This may change interface id for your gif interface.  be careful upgrading
  rc files.

(sync with recent KAME)

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 (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.
