pull request: wireless-next 2014-06-02
Please pull this remaining batch of updates intended for the 3.16 stream...
For the mac80211 bits, Johannes says:
"The remainder for -next right now is mostly fixes, and a handful of
small new things like some CSA infrastructure, the regdb script mW/dBm
conversion change and sending wiphy notifications."
For the bluetooth bits, Gustavo says:
"Some more patches for 3.16. There is nothing really special here, just a
bunch of clean ups, fixes plus some small improvements. Please pull."
For the nfc bits, Samuel says:
"We have:
- Felica (Type3) tags support for trf7970a
- Type 4b tags support for port100
- st21nfca DTS typo fix
- A few sparse warning fixes"
For the atheros bits, Kalle says:
"Ben added support for setting antenna configurations. Michal improved
warm reset so that we would not need to fall back to cold reset that
often, an issue where ath10k stripped protected flag while in monitor
mode and made module initialisation asynchronous to fix the problems
with firmware loading when the driver is linked to the kernel.
Luca removed unused channel_switch_beacon callbacks both from ath9k and
ath10k. Marek fixed Protected Management Frames (PMF) when using Action
Frames. Also we had other small fixes everywhere in the driver."
Along with that, there are a handful of updates to a variety
of drivers. This includes updates to at76c50x-usb, ath9k, b43,
brcmfmac, mwifiex, rsi, rtlwifi, and wil6210.

Ideally, we would need to generate IP ID using a per destination IP
generator.
linux kernels used inet_peer cache for this purpose, but this had a huge
cost on servers disabling MTU discovery.
1) each inet_peer struct consumes 192 bytes
2) inetpeer cache uses a binary tree of inet_peer structs,
with a nominal size of ~66000 elements under load.
3) lookups in this tree are hitting a lot of cache lines, as tree depth
is about 20.
4) If server deals with many tcp flows, we have a high probability of
not finding the inet_peer, allocating a fresh one, inserting it in
the tree with same initial ip_id_count, (cf secure_ip_id())
5) We garbage collect inet_peer aggressively.
IP ID generation do not have to be 'perfect'
Goal is trying to avoid duplicates in a short period of time,
so that reassembly units have a chance to complete reassembly of
fragments belonging to one message before receiving other fragments
with a recycled ID.
We simply use an array of generators, and a Jenkin hash using the dst IP
as a key.
ipv6_select_ident() is put back into net/ipv6/ip6_output.c where it
belongs (it is only used from this file)
secure_ip_id() and secure_ipv6_id() no longer are needed.
Rename ip_select_ident_more() to ip_select_ident_segs() to avoid
unnecessary decrement/increment of the number of segments.

====================
Provide common means for device address sync
The following series implements a means for synchronizing both unicast and
multicast addresses on a device interface. The code is based on the original
implementation of dev_uc_sync that was available for syncing a VLAN to the
lower dev.
The original reason for coming up for this patch is a driver that is still in
the early stages of development. The nearest driver I could find that
appeared to have the same limitations as the driver I was working on was the
Cisco enic driver. For this reason I chose it as the first driver to make use
of this interface publicly.
However, I do not have a Cisco enic interface so I have only been able to
compile test any changes made to the driver. I tried to keep this change as
simple as possible to avoid any issues. Any help with testing would be
greatly appreciated.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
This change updates the enic driver to make use of __dev_uc_sync and
__dev_mc_sync calls. Previously the driver was doing its own list
management by storing the mc_addr and uc_addr list in a 32 address array.
With this change the sync data is stored in the netdev_addr_list structures
and instead we just track how many addresses we have written to the device.
When we encounter 32 we stop and print a message as occurred previously with
the old approach.
Other than the core change the only other bit needed was to propagate the
constant attribute with the MAC address as there were several spots where
is twas only passed as a u8 * instead of a const u8 *.
This patch is meant to maintain the original functionality without the use
of the mc_addr and uc_addr arrays.

This change provides a function to be used in order to break the
ndo_set_rx_mode call into a set of address add and remove calls. The code
is based on the implementation of dev_uc_sync/dev_mc_sync. Since they
essentially do the same thing but with only one dev I simply named my
functions __dev_uc_sync/__dev_mc_sync.
I also implemented an unsync version of the functions as well to allow for
cleanup on close.

This patch fix the 6LoWPAN fragmentation for the case if we have exactly
two fragments. The problem is that the (skb_unprocessed >= frag_cap)
condition is always false on the second fragment after sending the first
fragment. A fragmentation with only one fragment doesn't make any sense.
The solution is that we use a do while loop here, that ensures we sending
always a minimum of two fragments if we need a fragmentation.

It is possible that after entering runtime PM suspend the controller

example on Asus T100, an Intel Baytrail based tablet/laptop.
In order to get the controller back to functional state, we need to
implement runtime PM hooks which will re-initialize the hardware during
runtime PM resume. We can re-use the existing system suspend hooks as the
steps to resume/suspend the controller are the same.

Arnd said in another patch:
"As far as I can tell, this driver must have produced this
error for as long as it has been merged into the mainline kernel, but
it was never part of the normal build tests:
drivers/i2c/busses/i2c-nuc900.c: In function 'nuc900_i2c_probe':
drivers/i2c/busses/i2c-nuc900.c:601:17: error: request for member
'apbfreq' in something not a structure or union
ret = (i2c->clk.apbfreq)/(pdata->bus_freq * 5) - 1;
^
This is an attempt to get the driver to build and possibly
work correctly, although I do wonder whether we should just
remove it, as it has clearly never worked."
I agree with removing it since nobody showed interest in Arnd's fixup
patch.

Since IMX serial SOCs support low bus freq mode, some clocks freq
may change to save power. I2C needs to check the clock source and
update the divider.
For example:
i.MX6SL I2C clk is from IPG_PERCLK which is sourced from IPG_CLK.
Under normal operation, IPG_CLK is 66MHz, ipg_perclk is at 22MHz.
In low bus freq mode, IPG_CLK is at 12MHz and IPG_PERCLK is down
to 4MHz. So the I2C driver must update the divider register for
each transaction when the current IPG_PERCLK is not equal to the
clock of previous transaction.

read -> repeat restart -> read/write
The current i2c imx host controller driver don't support this
operation that causes i2c bus hang due to "MTX" is cleared in
.i2c_imx_read(). If "read" is the last message there have no problem,
so the current driver supports all SMbus operation like:
write -> repeat restart -> read/write
IMX i2c controller for master receiver has some limitation:
- If it is the last byte for one operation, it must generate STOP
signal before read I2DR to prevent controller from generating another
clock cycle.
- If it is the last byte in the read, and then do repeat restart, it must
set "MTX" before read I2DR to prevent controller from generating another
extra clock cycle.
The patch is to fix the issue.

Pull block core updates from Jens Axboe:
"It's a big(ish) round this time, lots of development effort has gone
into blk-mq in the last 3 months. Generally we're heading to where
3.16 will be a feature complete and performant blk-mq. scsi-mq is
progressing nicely and will hopefully be in 3.17. A nvme port is in
progress, and the Micron pci-e flash driver, mtip32xx, is converted
and will be sent in with the driver pull request for 3.16.
This pull request contains:
- Lots of prep and support patches for scsi-mq have been integrated.
All from Christoph.
- API and code cleanups for blk-mq from Christoph.
- Lots of good corner case and error handling cleanup fixes for
blk-mq from Ming Lei.
- A flew of blk-mq updates from me:
* Provide strict mappings so that the driver can rely on the CPU
to queue mapping. This enables optimizations in the driver.
* Provided a bitmap tagging instead of percpu_ida, which never
really worked well for blk-mq. percpu_ida relies on the fact
that we have a lot more tags available than we really need, it
fails miserably for cases where we exhaust (or are close to
exhausting) the tag space.
* Provide sane support for shared tag maps, as utilized by scsi-mq
* Various fixes for IO timeouts.
* API cleanups, and lots of perf tweaks and optimizations.
- Remove 'buffer' from struct request. This is ancient code, from
when requests were always virtually mapped. Kill it, to reclaim
some space in struct request. From me.
- Remove 'magic' from blk_plug. Since we store these on the stack
and since we've never caught any actual bugs with this, lets just
get rid of it. From me.
- Only call part_in_flight() once for IO completion, as includes two
atomic reads. Hopefully we'll get a better implementation soon, as
the part IO stats are now one of the more expensive parts of doing
IO on blk-mq. From me.
- File migration of block code from {mm,fs}/ to block/. This
includes bio.c, bio-integrity.c, bounce.c, and ioprio.c. From me,
from a discussion on lkml.
That should describe the meat of the pull request. Also has various
little fixes and cleanups from Dave Jones, Shaohua Li, Duan Jiong,
Fengguang Wu, Fabian Frederick, Randy Dunlap, Robert Elliott, and Sam
Bradshaw"

The below patches have been worked on in the linux-omap mailinglist
for 10 months and are well tested in linux-next (have been in there
for more than two weeks) without any problems arising. Apart from
that potential regressions are very limited, because the subsystem is
not yet used by any platform in the mainline kernel.
- Add some documentation for the HSI subsystem
- Add Device Tree support for the HSI subsystem
- Add OMAP3 SSI driver (SSI is a legacy variant of HSI)
- Add Nokia N900 Modem driver (without speech support for now)"
