inet6: Send RTM_MISS when we fail to resolve an address.

Takes the same approach as when adding a new address - we no longer
announce the new lladdr right away but we announce the result.

This will either be RTM_ADD or RTM_MISS.
RTM_DELETE is only sent if we have a lladdr assigned OR gc'ed.

This results in less messages via route(4) and tells us when a new
lladdr has been added (RTM_ADD), changed (RTM_CHANGE), deleted
(RTM_DELETED) or has failed to been resolved (RTM_MISS).

The latter case can be interpreted as unreachable.

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.

Protect sysctl_rtable with KERNEL_LOCK and softnet_lock

In the function the routing table could be accessed without any locks, which was
unsafe.  Actually, on netbsd-7, a kernel panic happened(*).  The situation of
locking hasn't changed since netbsd-7 so we still need to hold the big locks on
-current (and netbsd-8) too.

Note that if NET_MPSAFE is enabled, the routing table is protected by its own
lock and we don't need the locks.

Convert the MODULE_{,VOID_}HOOK_CALL macros to do everything in-line
rather than defining an intermediate hook##call function.  Almost
all of the hooks are called only once, and although we lose the
ability of doing things like

	if (MODULE_HOOK_CALL(...) == 0) ...

we simplify things quite a bit.  With this change, we no longer need
to have both declaration and definition macros, and the definition
no longer needs to have both prototype argument list and a "real"
argument list.

FWIW, the above if now needs to written as

	int ret;

	MODULE_HOOK_CALL(..., ret);
	if (ret == 0) ...

with appropriate use of braces {}.

for returning a non-int return value).

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 the HOOK2 versions of the MODULE_HOOK macros.  There were
only a few uses, and using them led to some lack of clarity in the
code.  Instead, we now use two separate hooks, with names that
make it clear(er) what we're doing.

This also positions us to start unraveling some of the rtsock_50
mess, which will need (at least) five hooks.

Split the COMPAT_CALL_HOOK to separate the declaration from the
implementation.  Some hooks are called from multiple source files,
and the old method resulted in duplicate implementations.

Implement MP-safe hooks for the usb_subr_30 code.  Pass the helper
functions as arguments to the compat code so it does not have to
determine if the kernel contains usb code.

socket: report receive buffer overflows
Add soroverflow() which increments the overflow counter, sets so_error
to ENOBUFS and wakes the receive socket up.
Replace all code that manually increments this counter with soroverflow().
Add soroverflow() to raw_input().
This allows userland to detect route(4) overflows so it can re-sync
with the current state.
socket: clear error even when peeking
The error has already been reported and it's pointless requiring another
recv(2) call just to clear it.
socket: remove now incorrect comment that so_error is only udp
As it can be affected by route(4) sockets which are raw.
rtsock: log dropped messages that we cannot report to userland
Handle ENOBUFS when receiving messages.
Don't send messages if the receiver has died.
Sprinkle more soroverflow().
Handle ENOBUFS in recv
Handle ENOBUFS in sendto
Note value received. Harden another sendto for ENOBUFS.
Handle the routing socket overflowing gracefully.
Allow a valid sendto .... duh
Handle errors better.
Fix test for checking we sent all the data we asked to.

Run tcp_slowtimo in workqueue if NET_MPSAFE
If NET_MPSAFE is enabled, we have to avoid taking softnet_lock in softint as

undesired delays of executing subsequent softint handlers.

to a target route (except for a reference by the updater itself) to be released.

the ifp from being freed. However route_output_get_ifa can return an ifp
to which a returned ifa doesn't belong. So we need to take a reference
to a returning ifp separately.

Unify IFEF_*_MPSAFE into IFEF_MPSAFE
There are already two flags for if_output and if_start, however, it seems such
MPSAFE flags are eventually needed for all if_XXX operations. Having discrete
flags for each operation is wasteful of if_extflags bits. So let's unify
the flags into one: IFEF_MPSAFE.
Fortunately IFEF_*_MPSAFE flags have never been included in any releases, so
we can change them without breaking backward compatibility of the releases
(though the kernel version of -current should be bumped).
Note that if an interface have both MP-safe and non-MP-safe operations at a
time, we have to set the IFEF_MPSAFE flag and let callees of non-MP-safe
opeartions take the kernel lock.
Proposed on tech-kern@ and tech-net@
Provide macros for softnet_lock and KERNEL_LOCK hiding NET_MPSAFE switch
It reduces C&P codes such as "#ifndef NET_MPSAFE KERNEL_LOCK(1, NULL); ..."
scattered all over the source code and makes it easy to identify remaining
KERNEL_LOCK and/or softnet_lock that are held even if NET_MPSAFE.
No functional change
Hold KERNEL_LOCK on if_ioctl selectively based on IFEF_MPSAFE
If IFEF_MPSAFE is set, hold the lock and otherwise don't hold.
This change requires additions of KERNEL_LOCK to subsequence functions from
if_ioctl such as ifmedia_ioctl and ifioctl_common to protect non-MP-safe
components.
Proposed on tech-kern@ and tech-net@
Ensure to hold if_ioctl_lock when calling if_flags_set
Fix locking against myself on ifpromisc
vlan_unconfig_locked could be called with holding if_ioctl_lock.
Ensure to not turn on IFF_RUNNING of an interface until its initialization completes
And ensure to turn off it before destruction as per IFF_RUNNING's description
"resource allocated". (The description is a bit doubtful though, I believe the
change is still proper.)
Ensure to hold if_ioctl_lock on if_up and if_down
One exception for if_down is if_detach; in the case the lock isn't needed
because it's guaranteed that no other one can access ifp at that point.
Make if_link_queue MP-safe if IFEF_MPSAFE
if_link_queue is a queue to store events of link state changes, which is
used to pass events from (typically) an interrupt handler to
if_link_state_change softint. The queue was protected by KERNEL_LOCK so far,
but if IFEF_MPSAFE is enabled, it becomes unsafe because (perhaps) an interrupt
handler of an interface with IFEF_MPSAFE doesn't take KERNEL_LOCK. Protect it
by a spin mutex.
Additionally with this change KERNEL_LOCK of if_link_state_change softint is
omitted if NET_MPSAFE is enabled.
Note that the spin mutex is now ifp->if_snd.ifq_lock as well as the case of
if_timer (see the comment).
Use IFADDR_WRITER_FOREACH instead of IFADDR_READER_FOREACH
At that point no other one modifies the list so IFADDR_READER_FOREACH
is unnecessary. Use of IFADDR_READER_FOREACH is harmless in general though,
if we try to detect contract violations of pserialize, using it violates
the contract. So avoid using it makes life easy.
Ensure to call if_addr_init with holding if_ioctl_lock
Get rid of outdated comments

Rename IFNET_LOCK to IFNET_GLOBAL_LOCK

Also if_ioctl_lock perhaps needs to be renamed to something because it's now

- Destroy if_ioctl_lock at the end of the if_detach because it's used in various

Ensure to call if_mcast_op with holding IFNET_LOCK
Note that CARP doesn't deal with IFNET_LOCK yet.

Describe which lock is used to protect each member variable of struct ifnet
Requested by skrll@
Write a guideline for converting an interface to IFEF_MPSAFE
Requested by skrll@
Note that IFNET_LOCK must not be held in softint
Don't set IFEF_MPSAFE unless NET_MPSAFE at this point
Because recent investigations show that interfaces with IFEF_MPSAFE need to
follow additional restrictions to work with the flag safely. We should enable it
on an interface by default only if the interface surely satisfies the
restrictions, which are described in if.h.
Note that enabling IFEF_MPSAFE solely gains a few benefit on performance because
the network stack is still serialized by the big kernel locks by default.

Protect ifp returned from route_output_get_ifa surely

An ifp returned from route_output_get_ifa was supposed to be protected
by a returned ifa; if the ifa belongs to ifp, holding the ifa prevents
the ifp from being freed. However route_output_get_ifa can return an ifp
to which a returned ifa doesn't belong. So we need to take a reference

Updating an SA (SADB_UPDATE) requires that a process issuing

useful for testing (and debugging) purposes.

Remove codes for PACKET_TAG_IPSEC_IN_CRYPTO_DONE

It seems that PACKET_TAG_IPSEC_IN_CRYPTO_DONE is for network adapters
that have IPsec accelerators; a driver sets the mtag to a packet
when its device has already encrypted the packet.

Unfortunately no driver implements such offload features for long
years and seems unlikely to implement them soon. (Note that neither
FreeBSD nor Linux doesn't have such drivers.) Let's remove related
(unused) codes and simplify the IPsec code.

Prepare to stop using isr->sav

isr is a shared resource and using isr->sav as a temporal storage

new one. Let's have a sav locally for each packet processing instead of
using shared isr->sav.

However this change doesn't stop using isr->sav yet because there are
some users of isr->sav. isr->sav will be removed after the users find
a way to not use isr->sav.

AH authentication and M_AUTHIPDGM never be set to a mbuf. So

Hold a reference to an SP during opencrypto processing

An SP has a list of isr (ipsecrequest) that represents a sequence
of IPsec encryption/authentication processing. One isr corresponds
to one opencrypto processing. The lifetime of an isr follows its SP.

We pass an isr to a callback function of opencrypto to continue
to a next encryption/authentication processing. However nobody
guaranteed that the isr wasn't freed, i.e., its SP wasn't destroyed.

In order to avoid such unexpected destruction of isr, hold a reference
to its SP during opencrypto processing.

look-up degrades performance. A sav is later looked up in
ipsec4_process_packet so delay the fragmentation check until then
to avoid an extra look-up.

Fix key_getcomb_setlifetime

The fix adjusts a soft limit to be 80% of a corresponding hard limit.

I'm not sure the fix is really correct though, at least the original
code is wrong. A passed comb is zero-cleared before calling
key_getcomb_setlifetime, so
  comb->sadb_comb_soft_addtime = comb->sadb_comb_soft_addtime * 80 / 100;
is meaningless.

---
Let PF_KEY socks hold their own lock instead of softnet_lock

Operations on SAD and SPD are executed via PF_KEY socks. The operations
include deletions of SAs and SPs that will use synchronization mechanisms
such as pserialize_perform to wait for references to SAs and SPs to be
released. It is known that using such mechanisms with holding softnet_lock
causes a dead lock. We should avoid the situation.
---
Make IPsec SPD MP-safe

We use localcount(9), not psref(9), to make the sptree and secpolicy (SP)
entries MP-safe because SPs need to be referenced over opencrypto
processing that executes a callback in a different context.

SPs on sockets aren't managed by the sptree and can be destroyed in softint.
localcount_drain cannot be used in softint so we delay the destruction of
such SPs to a thread context. To do so, a list to manage such SPs is added
(key_socksplist) and key_timehandler_spd deletes dead SPs in the list.

For more details please read the locking notes in key.c.

Fix KASSERT(solocked(sb->sb_so)) failure in sbappendaddr that is called eventually from key_sendup_mbuf

If key_sendup_mbuf isn't passed a socket, the assertion fails.
Originally in this case sb->sb_so was softnet_lock and callers
held softnet_lock so the assertion was magically satisfied.
Now sb->sb_so is key_so_mtx and also softnet_lock isn't always
held by callers so the assertion can fail.

Fix it by holding key_so_mtx if key_sendup_mbuf isn't passed a socket.

Fix deadlock between key_sendup_mbuf called from key_acquire and localcount_drain

If we call key_sendup_mbuf from key_acquire that is called on packet
processing, a deadlock can happen like this:
- At key_acquire, a reference to an SP (and an SA) is held
- key_sendup_mbuf will try to take key_so_mtx
- Some other thread may try to localcount_drain to the SP with
  holding key_so_mtx in say key_api_spdflush
- In this case localcount_drain never return because key_sendup_mbuf
  that has stuck on key_so_mtx never release a reference to the SP

Fix the deadlock by deferring key_sendup_mbuf to the timer
(key_timehandler).

Fix race condition on the rawcb list shared by rtsock and keysock

Fix deadlock between pserialize_perform and localcount_drain

A typical ussage of localcount_drain looks like this:

  mutex_enter(&mtx);
  item = remove_from_list();
  pserialize_perform(psz);
  localcount_drain(&item->localcount, &cv, &mtx);
  mutex_exit(&mtx);

This sequence can cause a deadlock which happens for example on the following
situation:

- Thread A calls localcount_drain which calls xc_broadcast after releasing
  a specified mutex
- Thread B enters the sequence and calls pserialize_perform with holding
  the mutex while pserialize_perform also calls xc_broadcast
- Thread C (xc_thread) that calls an xcall callback of localcount_drain tries
  to hold the mutex

xc_broadcast of thread B doesn't start until xc_broadcast of thread A
finishes, which is a feature of xcall(9). This means that pserialize_perform
never complete until xc_broadcast of thread A finishes. On the other hand,
thread C that is a callee of xc_broadcast of thread A sticks on the mutex.
Finally the threads block each other (A blocks B, B blocks C and C blocks A).

A possible fix is to serialize executions of the above sequence by another
mutex, but adding another mutex makes the code complex, so fix the deadlock
by another way; the fix is to release the mutex before pserialize_perform
and instead use a condvar to prevent pserialize_perform from being called
simultaneously.

Note that the deadlock has happened only if NET_MPSAFE is enabled.

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.

Fix race condition on ifqueue used by traditional netisr

If a underlying network device driver supports MSI/MSI-X, RX interrupts
can be delivered to arbitrary CPUs. This means that Layer 2 subroutines
such as ether_input (softint) and subsequent Layer 3 subroutines (softint)
which are called via traditional netisr can be dispatched on an arbitrary
CPU. Layer 2 subroutines now run without any locks (expected) and so a
Layer 2 subroutine and a Layer 3 subroutine can run in parallel.

There is a shared data between a Layer 2 routine and a Layer 3 routine,
that is ifqueue and IF_ENQUEUE (from L2) and IF_DEQUEUE (from L3) on it
are racy now.

To fix the race condition, use ifqueue#ifq_lock to protect ifqueue
instead of splnet that is meaningless now.

The same race condition exists in route_intr. Fix it as well.

original ifnet list (ifnet_list) to avoid breaking kvm(3) users. We
shouldn't use the original list in the kernel anymore.

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/.

Eliminate struct protosw::pr_output.

You can't use this unless you know what it is a priori: the formal
prototype is variadic, and the different instances (e.g., ip_output,
route_output) have different real prototypes.

Convert the only user of it, raw_send in net/raw_cb.c, to take an
explicit callback argument.  Convert the only instances of it,
route_output and key_output, to such explicit callbacks for raw_send.
Use assertions to make sure the conversion to explicit callbacks is
warranted.

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.)

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.

return EOPNOTSUPP for pr_stat instead of returning success since we
don't fill in the struct stat passed to us.

* split PRU_SENSE functionality out of xxx_usrreq() switches and place into
  separate xxx_stat(struct socket *, struct stat *) functions.
* replace calls using pr_generic with req == PRU_SENSE with pr_stat().

further change will follow that cleans up the pattern used to extract the
pcb and test for its presence.

fix parameter types in pr_ioctl, called xx_control() functions and remove
abuse of pointer to struct mbuf type.

param2 changed to u_long type and uses parameter name 'cmd' (ioctl command)
param3 changed to void * type and uses parameter name 'data'
param4 changed to struct ifnet * and uses parameter name 'ifp'
param5 has been removed (formerly struct lwp *) and uses of 'l' have been
       replaced with curlwp from curproc(9).

callers have had (now unnecessary) casts to struct mbuf * removed, called
code has had (now unnecessary) casts to u_long, void * and struct ifnet *
respectively removed.

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:
                ...
                break;
        case IFF_UP|IFF_RUNNING:
                ...
                break;
        }

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
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.

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.

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.

First take at security model abstraction.

- Add a few scopes to the kernel: system, network, and machdep.

- Add a few more actions/sub-actions (requests), and start using them as
  opposed to the KAUTH_GENERIC_ISSUSER place-holders.

- Introduce a basic set of listeners that implement our "traditional"
  security model, called "bsd44". This is the default (and only) model we
  have at the moment.

- Update all relevant documentation.

- Add some code and docs to help folks who want to actually use this stuff:

  * There's a sample overlay model, sitting on-top of "bsd44", for
    fast experimenting with tweaking just a subset of an existing model.

    This is pretty cool because it's *really* straightforward to do stuff
    you had to use ugly hacks for until now...

  * And of course, documentation describing how to do the above for quick
    reference, including code samples.

All of these changes were tested for regressions using a Python-based
testsuite that will be (I hope) available soon via pkgsrc. Information
about the tests, and how to write new ones, can be found on:

	http://kauth.linbsd.org/kauthwiki

NOTE FOR DEVELOPERS: *PLEASE* don't add any code that does any of the
following:

  - Uses a KAUTH_GENERIC_ISSUSER kauth(9) request,
  - Checks 'securelevel' directly,
  - Checks a uid/gid directly.

(or if you feel you have to, contact me first)

This is still work in progress; It's far from being done, but now it'll
be a lot easier.

Many thanks to YAMAMOTO Takashi, Matt Thomas, and Christos Zoulas for help
stablizing kauth(9).

Full credit for the regression tests, making sure these changes didn't break
anything, goes to Matt Fleming and Jaime Fournier.

Happy birthday Randi! :)

Pull up revision 1.72 via patch (requested by christos in ticket #961):
PR/27286: Tom Ivar Helbekkmo: Allow RTM_GET to work with RTA_IFA|RTA_IFP set.
Quiting Tom: The problem is the special case of an RTM_GET message
that wants interface information included in the response, and
therefore include the RTA_IFA or RTA_IFP (or both) flags in the
bitmask that says what addresses are supplied in the message.  For
the RTM_GET message, it doesn't make sense to supply addresses
other than the one you're asking about, so those two other bits
are, in that specific case, overloaded with this meaning.
There is code in sys/net/rtsock.c to handle the case, but at some
time, extra sanity checking of the received message was added, that
failed to take this possibility into account.
The patch, is needed for the Asterisk software PBX to work properly
when it has multiple interfaces active: it needs to ask the kernel
for the IP address of the interface that will be used to communicate
with a given host.

Sysctl functions called for "generic" nodes should forward "query"
requests (where possible), rather than returning errors.

Dynamic sysctl.

Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al.  Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded.  Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment.  I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

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.

Curproc->curlwp renaming.

Change uses of "curproc->l_proc" back to "curproc", which is more like the

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)
so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

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)

eon_rtrequest() and rtrequest() were incorrect since 4.3BSD-reno,

- Add link status to if_data, so that routing daemons and other interested
  parties can easily know the state of a link.
- Define an interface announcement message for the routing socket so that
  routing daemons and other interested parties know when an interface
  is attached/detached.

backout incomplete hack from KAME codebase (originally from bbn).

the hack tries to respect ifa or ifp passed to RTM_ADD.  However, the change
broke certain link-layers.  They include:
- midway ethernet card (en*), which uses sockaddr_dl in gateway portion
  to pass PVC information.  with the patch, the gateway portion will be
  overwritten by empty sockaddr_dl and PVC initialization will fail.
- IPv6, which can't set static ND table with the patch (ndp -s), for the
  similar reason as above.

There may be improved hack coming soon, hope the new one does not break others.

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.

RTM_IFINFO is now 0xf, 0xe is RTM_OIFINFO which returns the old (if_msghdr14)

Same for sysctl: node 3 is renamed NET_RT_OIFLIST, NET_RT_IFLIST is now node 4.
Change rt_msg1() to add an mbuf to the mbuf chain instead of just panic()
when the message is larger than MHLEN.

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.
