Drivers can usually handle fragmented packets
much easier when they get the entire list of
fragments at once. The only thing they need to
do is keep enough space on the queues for up
to ten fragments of a single MSDU.
This allows them to implement this with a new
operation tx_frags.

The management protocol uses a single byte for error codes (aka command
status). In some places this value is directly copied from HCI and in
other a POSIX error number is used. This makes it impossible for
user-space to uniquily decipher the meaning of an error.
To solve this issue a new mgmt-specific set of error codes is added
along with a conversion table for HCI status values.

The 802.1X EAPOL handshake hostapd does requires
knowing whether the frame was ack'ed by the peer.
Currently, we fudge this pretty badly by not even
transmitting the frame as a normal data frame but
injecting it with radiotap and getting the status
out of radiotap monitor as well. This is rather
complex, confuses users (mon.wlan0 presence) and
doesn't work with all hardware.
To get rid of that hack, introduce a real wifi TX
status option for data frame transmissions.
This works similar to the existing TX timestamping
in that it reflects the SKB back to the socket's
error queue with a SCM_WIFI_STATUS cmsg that has
an int indicating ACK status (0/1).
Since it is possible that at some point we will
want to have TX timestamping and wifi status in a
single errqueue SKB (there's little point in not
doing that), redefine SO_EE_ORIGIN_TIMESTAMPING
to SO_EE_ORIGIN_TXSTATUS which can collect more
than just the timestamp; keep the old constant
as an alias of course. Currently the internal APIs
don't make that possible, but it wouldn't be hard
to split them up in a way that makes it possible.

The current global pending command list in mgmt.c is racy. Possibly the
simplest way to fix it is to have per-hci dev lists instead of a global
one (all commands that need a pending struct are hci_dev specific).
This way the list can be protected using the already existing per-hci
dev lock. To enable this refactoring the first thing that needs to be
done is to ensure that the mgmt functions have access to the hci_dev
struct (instead of just the dev id).

the tcp and udp code creates a set of struct file_operations at runtime
while it can also be done at compile time, with the added benefit of then
having these file operations be const.
the trickiest part was to get the "THIS_MODULE" reference right; the naive
method of declaring a struct in the place of registration would not work
for this reason.

This patch exports several definitions that used to live under
include/net/netfilter/nf_nat.h. These definitions, although not
exported, have been used by iptables and other userspace
applications like miniupnpd since long time. Basically, these
userspace tools included some internal definition of the required
structures and they assume no changes in the binary representation
(which is OK indeed).
To resolve this situation, this patch makes public the required
structure and install them in INSTALL_HDR_PATH.
See: https://bugs.gentoo.org/376873, for more information.
This patch is heavily based on the initial patch sent by:

These two small inlines make calls to try_module_get() and
module_put() which would force us to keep module.h present
within yet another common include header. We can avoid this
by turning them into macros. The hci_dev_hold construct
is patterned off of raw_spin_trylock_irqsave() in spinlock.h

This file was using the module get/put functions in two simple inline
functions. But module_get/put were only within scope because of
the implicit presence of module.h being everywhere.
Rather than add module.h to another file in include/ -- which is
exactly the thing we are trying to avoid, simply convert these
one-line functions into a define, as per what was done for the
device_schedule_callback() in commit 523ded71de.

The implicit presence of module.h everywhere meant that this header
also was getting moduleparam.h which defines struct kernel_param.
Since it only needs to know that kernel_param is a struct, call that
out instead of adding an include of moduleparam.h -- to get rid of this:
include/net/netfilter/nf_conntrack.h:316: warning: 'struct kernel_param' declared inside parameter list
include/net/netfilter/nf_conntrack.h:316: warning: its scope is only this definition or declaration, which is probably not what you want
Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
The <linux/module.h> pretty much brings in the kitchen sink along
with it, so it should be avoided wherever reasonably possible in
terms of being included from other commonly used <linux/something.h>
files, as it results in a measureable increase on compile times.
The worst culprit was probably device.h since it is used everywhere.
This file also had an implicit dependency/usage of mutex.h which was
masked by module.h, and is also fixed here at the same time.
There are over a dozen other headers that simply declare the
struct instead of pulling in the whole file, so follow their lead
and simply make it a few more.
Most of the implicit dependencies on module.h being present by
these headers pulling it in have been now weeded out, so we can
finally make this change with hopefully minimal breakage.

This file has modular references, but they are limited to
those which are covered by the simple "struct module;"
declaration used in dozens of other places. In fact that
declaration is already there (just outside of the context
of this commit) so simply remove the include line.

There is nothing module specific in this header, and removing
it doesn't seem to uncover any implicit dependencies either.

This part is for the IPv6 side, adding a tclass param to ip6_xmit()

There is a long standing bug in linux tcp stack, about ACK messages sent
on behalf of TIME_WAIT sockets.
In the IP header of the ACK message, we choose to reflect TOS field of
incoming message, and this might break some setups.
Example of things that were broken :
- Routing using TOS as a selector
- Firewalls
- Trafic classification / shaping
We now remember in timewait structure the inet tos field and use it in
ACK generation, and route lookup.
Notes :
- We still reflect incoming TOS in RST messages.
- We could extend MuraliRaja Muniraju patch to report TOS value in
netlink messages for TIME_WAIT sockets.
- A patch is needed for IPv6

Adding const qualifiers to pointers can ease code review, and spot some

For example, is it legal to temporary write a null cksum into tcphdr
in tcp_md5_hash_header() ? I am afraid a sniffer could catch the
temporary null value...
