YOSHIFUJI Hideaki f6a07b293f [IPV6] ADDRCONF: Fix array size for sysctls.
We have been using __NET_IPV6_MAX for adjusting the size of array
for sysctl table, but it does not work any longer because of the
deprecation of NET_IPV6_xxx constants.  Let's use DEVCONF_MAX
instead.

Denis V. Lunev eb86757931 [IPV6]: inet6_dev on loopback should be kept until namespace stop.
In the other case it will be destroyed when last address will be removed
from lo inside a namespace. This will break IPv6 in several places. The
most obvious one is ip6_dst_ifdown.

Denis V. Lunev 439e23857a [IPV6]: Event type in addrconf_ifdown is mis-used.
addrconf_ifdown is broken in respect to the usage of how
parameter. This function is called with (event != NETDEV_DOWN) and (2)
on the IPv6 stop.  It the latter case inet6_dev from loopback device
should be destroyed.

Benjamin Thery 6fda735005 [NETNS][IPV6] addrconf - make addrconf per namespace
All the infrastructure to propagate the network namespace information
is ready. Make use of it.

There is a special case here between the initial network namespace and
the other namespaces:

* When ipv6 is initialized at boot time (aka in the init_net), it
registers to the notifier callback. So addrconf_notify will be called
as many time as there are network devices setup on the system and the
function will add ipv6 addresses to the network devices. But the first
device which needs to have its ipv6 address setup is the loopback,
unfortunatly this is not the case. So the loopback address is setup
manually in the ipv6 init function.

* With the network namespace, this ordering problem does not appears
because notifier is already setup and active, so as soon as we
register the loopback the ipv6 address is setup and it will be the
first device.

Pavel Emelyanov f52295a9c5 [IPV6]: Unify and cleanup calls to addrconf_sysctl_register
Currently this call is (ab)used similar to devinet one - it
registers sysctls for devices and for the "default" confs, while
the "all" sysctls are registered separately. But unlike its
devinet brother, the passed inet6_device is needed.

The fix is to make a __addrconf_sysctl_register(), which registers
sysctls for all "devices" we need, including "default" and "all" :)

The original addrconf_sysctl_register() calls the introduced
function, passing the inet6_device, device name and ifindex (to
be used as procname and ctl_name) into it.

Thanks to Herbert again for pointing out, that we can shrink the
argument list to 1 :)

Avaid provided test application, so bug got fixed.

IPv6 addrconf removes ipv6 inner device from netdev each time cmu
changes and new value is less than IPV6_MIN_MTU (1280 bytes).
When mtu is changed and new value is greater than IPV6_MIN_MTU,
it does not add ipv6 addresses and inner device bac.

David L Stevens 14878f75ab [IPV6]: Add ICMPMsgStats MIB (RFC 4293) [rev 2]
Background: RFC 4293 deprecates existing individual, named ICMP
type counters to be replaced with the ICMPMsgStatsTable. This table
includes entries for both IPv4 and IPv6, and requires counting of all
ICMP types, whether or not the machine implements the type.

These patches "remove" (but not really) the existing counters, and
replace them with the ICMPMsgStats tables for v4 and v6.
It includes the named counters in the /proc places they were, but gets the
values for them from the new tables. It also counts packets generated
from raw socket output (e.g., OutEchoes, MLD queries, RA's from
radvd, etc).

Changes:
1) create icmpmsg_statistics mib
2) create icmpv6msg_statistics mib
3) modify existing counters to use these
4) modify /proc/net/snmp to add "IcmpMsg" with all ICMP types
        listed by number for easy SNMP parsing
5) modify /proc/net/snmp printing for "Icmp" to get the named data
        from new counters.
[new to 2nd revision]
6) support per-interface ICMP stats
7) use common macro for per-device stat macros

Eric W. Biederman 881d966b48 [NET]: Make the device list and device lookups per namespace.
This patch makes most of the generic device layer network
namespace safe.  This patch makes dev_base_head a
network namespace variable, and then it picks up
a few associated variables.  The functions:
dev_getbyhwaddr
dev_getfirsthwbytype
dev_get_by_flags
dev_get_by_name
__dev_get_by_name
dev_get_by_index
__dev_get_by_index
dev_ioctl
dev_ethtool
dev_load
wireless_process_ioctl

were modified to take a network namespace argument, and
deal with it.

vlan_ioctl_set and brioctl_set were modified so their
hooks will receive a network namespace argument.

So basically anthing in the core of the network stack that was
affected to by the change of dev_base was modified to handle
multiple network namespaces.  The rest of the network stack was
simply modified to explicitly use &init_net the initial network
namespace.  This can be fixed when those components of the network
stack are modified to handle multiple network namespaces.

For now the ifindex generator is left global.

Fundametally ifindex numbers are per namespace, or else
we will have corner case problems with migration when
we get that far.

At the same time there are assumptions in the network stack
that the ifindex of a network device won't change.  Making
the ifindex number global seems a good compromise until
the network stack can cope with ifindex changes when
you change namespaces, and the like.

stack or a pseudo device.  If a protocol stack that does not have
support for multiple network namespaces receives an event for a

To avoid problems until all of the protocol stacks are converted
this patch modifies all netdev event handlers to ignore events on

checks can be removed.

This patch makes /proc/net per network namespace.  It modifies the global
variables proc_net and proc_net_stat to be per network namespace.
The proc_net file helpers are modified to take a network namespace argument,
and all of their callers are fixed to pass &init_net for that argument.
This ensures that all of the /proc/net files are only visible and
usable in the initial network namespace until the code behind them
has been updated to be handle multiple network namespaces.

Making /proc/net per namespace is necessary as at least some files
in /proc/net depend upon the set of network devices which is per
network namespace, and even more files in /proc/net have contents
that are relevant to a single network namespace.

Masahide NAKAMURA 59fbb3a61e [IPV6] MIP6: Loadable module support for MIPv6.
This patch makes MIPv6 loadable module named "mip6".

Here is a modprobe.conf(5) example to load it automatically
when user application uses XFRM state for MIPv6:

alias xfrm-type-10-43 mip6
alias xfrm-type-10-60 mip6

Some MIPv6 feature is not included by this modular, however,
it should not be affected to other features like either IPsec
or IPv6 with and without the patch.
We may discuss XFRM, MH (RAW socket) and ancillary data/sockopt
separately for future work.

Loadable features:
* MH receiving check (to send ICMP error back)
* RO header parsing and building (i.e. RH2 and HAO in DSTOPTS)
* XFRM policy/state database handling for RO

These are NOT covered as loadable:
* Home Address flags and its rule on source address selection
* XFRM sub policy (depends on its own kernel option)
* XFRM functions to receive RO as IPv6 extension header
* MH sending/receiving through raw socket if user application
  opens it (since raw socket allows to do so)
* RH2 sending as ancillary data
* RH2 operation with setsockopt(2)

Jay Vosburgh c2edacf80e bonding / ipv6: no addrconf for slaves separately from master
At present, when a device is enslaved to bonding, if ipv6 is
active then addrconf will be initated on the slave (because it is closed
then opened during the enslavement processing).  This causes DAD and RS
packets to be sent from the slave.  These packets in turn can confuse
switches that perform ipv6 snooping, causing them to incorrectly update
their forwarding tables (if, e.g., the slave being added is an inactve
backup that won't be used right away) and direct traffic away from the
active slave to a backup slave (where the incoming packets will be
dropped).

	This patch alters the behavior so that addrconf will only run on
the master device itself.  I believe this is logically correct, as it
prevents slaves from having an IPv6 identity independent from the
master.  This is consistent with the IPv4 behavior for bonding.

	This is accomplished by (a) having bonding set IFF_SLAVE sooner
in the enslavement processing than currently occurs (before open, not
after), and (b) having ipv6 addrconf ignore UP and CHANGE events on
slave devices.

	The eql driver also uses the IFF_SLAVE flag.  I inspected eql,
and I believe this change is reasonable for its usage of IFF_SLAVE, but
I did not test it.

Herbert Xu 74235a25c6 [IPV6] addrconf: Fix IPv6 on tuntap tunnels
The recent patch that added ipv6_hwtype is broken on tuntap tunnels.
Indeed, it's broken on any device that does not pass the ipv6_hwtype
test.

The reason is that the original test only applies to autoconfiguration,
not IPv6 support.  IPv6 support is allowed on any device.  In fact,
even with the ipv6_hwtype patch applied you can still add IPv6 addresses
to any interface that doesn't pass thw ipv6_hwtype test provided that
they have a sufficiently large MTU.  This is a serious problem because
come deregistration time these devices won't be cleaned up properly.

I've gone back and looked at the rationale for the patch.  It appears
that the real problem is that we were creating IPv6 devices even if the
MTU was too small.  So here's a patch which fixes that and reverts the
ipv6_hwtype stuff.

Michal Wrobel 2c12a74cc4 [IPV6]: anycast refcnt fix
This patch fixes a bug in Linux IPv6 stack which caused anycast address
to be added to a device prior DAD has been completed. This led to
incorrect reference count which resulted in infinite wait for
unregister_netdevice completion on interface removal.

Eric W. Biederman 3fbfa98112 [PATCH] sysctl: remove the proc_dir_entry member for the sysctl tables
It isn't needed anymore, all of the users are gone, and all of the ctl_table
initializers have been converted to use explicit names of the fields they are
initializing.

Eric W. Biederman 0b4d414714 [PATCH] sysctl: remove insert_at_head from register_sysctl
The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name.  Which is
pain for caching and the proc interface never implemented.

I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.

So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.

Tim Schmielau cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

Arjan van de Ven 9a32144e9d [PATCH] mark struct file_operations const 7
Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.
