2638698df3 [IRDA]: irlmp_unregister_link() needs to free lsaps.
While testing the mcs7780 based IrDA USB dongle I've stumbled upon
memory leak in irlmp_unregister_link(). Hashbin for lsaps is created in
irlmp_register_link and should probably be freed in irlmp_unregister_link().

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.

e730c15519 [NET]: Make packet reception network namespace safe
This patch modifies every packet receive function
registered with dev_add_pack() to drop packets if they
are not from the initial network namespace.

This should ensure that the various network stacks do
not receive packets in a anything but the initial network
namespace until the code has been converted and is ready
for them.

1b8d7ae42d [NET]: Make socket creation namespace safe.
This patch passes in the namespace a new socket should be created in
and has the socket code do the appropriate reference counting.  By
virtue of this all socket create methods are touched.  In addition
the socket create methods are modified so that they will fail if
you attempt to create a socket in a non-default network namespace.

Failing if we attempt to create a socket outside of the default
network namespace ensures that as we incrementally make the network stack
network namespace aware we will not export functionality that someone
has not audited and made certain is network namespace safe.
Allowing us to partially enable network namespaces before all of the
exotic protocols are supported.

Any protocol layers I have missed will fail to compile because I now
pass an extra parameter into the socket creation code.

457c4cbc5a [NET]: Make /proc/net per network namespace
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.

2c20d72aaa [IRDA]: Avoid a label defined but not used warning in irda_init()
Easily avoidable compiler warnings bug me.

Building irmod without CONFIG_SYSCTL currently results in :
 net/irda/irmod.c:132: warning: label 'out_err_2' defined but not used

But that can easily be avoided by simply moving the label inside
the existing "#ifdef CONFIG_SYSCTL" one line above it.

This patch moves the label and buys us one less warning with no
ill effects.

This is due to the irda_init fix recently added, where we call __exit

6e66aa15d8 [IrDA] af_irda: Silence kernel message in irda_recvmsg_stream
This patch silences an IRDA_ASSERT in irda_recvmsg_stream, as described in
http://bugzilla.kernel.org/show_bug.cgi?id=7512 irda_disconnect_indication
would set sk->sk_err to ECONNRESET, and a subsequent call to recvmsg
would print an irritating kernel message and return -1.

When a connected socket is closed by the peer, recvmsg should return 0
rather than an error. This patch fixes this.

305f2aa182 [IrDA] af_irda: irda_recvmsg_stream cleanup
This patch cleans up some code in irda_recvmsg_stream, replacing some
homebrew code with prepare_to_wait/finish_wait, and by making the
code honor sock_rcvtimeo.

3ff50b7997 [NET]: cleanup extra semicolons
Spring cleaning time...

There seems to be a lot of places in the network code that have
extra bogus semicolons after conditionals.  Most commonly is a
bogus semicolon after: switch() { }

27d7ff46a3 [SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}
To clearly state the intent of copying to linear sk_buffs, _offset being a
overly long variant but interesting for the sake of saving some bytes.

27a884dc3c [SK_BUFF]: Convert skb->tail to sk_buff_data_t
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes
on 64bit architectures, allowing us to combine the 4 bytes hole left by the
layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4
64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN...
:-)

Many calculations that previously required that skb->{transport,network,
mac}_header be first converted to a pointer now can be done directly, being
meaningful as offsets or pointers.

eeeb03745b [SK_BUFF]: More skb_put related conversions to skb_reset_transport_header
This is similar to the skb_reset_network_header(), i.e. at the point we reset
the transport header pointer/offset skb->tail is equal to skb->data.
