Here is the big Gadget & PHY pull request. Many of us have
been really busy lately getting multiple drivers to a better
position.
Since this pull request is so large, I will divide it in sections
so it's easier to grasp what's included.
- cleanups:
. UDC drivers no longer touch gadget->dev, that's now udc-core
responsibility
. Many more UDC drivers converted to usb_gadget_map/unmap_request()
. UDC drivers no longer initialize DMA-related fields from gadget's
device structure
. UDC drivers don't touch gadget.dev.driver directly
. UDC drivers don't assign gadget.dev.release directly
. Removal of some unused DMA_ADDR_INVALID
. Introduction of CONFIG_USB_PHY
. All phy drivers have been moved to drivers/usb/phy and renamed to
a common naming scheme
. Fix PHY layer so it never returns a NULL pointer, also fix all
callers to avoid using IS_ERR_OR_NULL()
. Sparse fixes all over the place
. drivers/usb/otg/ has been deleted
. Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock
usage
- new features:
. UDC core now provides a generic way for tracking and reporting
UDC's state (not attached, resuming, suspended, addressed,
default, etc)
. twl4030-usb learned that it shouldn't be enabled during init
. Full DT support for DWC3 has been implemented
. ab8500-usb learned about pinctrl framework
. nop PHY learned about DeviceTree and regulators
. DWC3 learned about suspend/resume
. DWC3 can now be compiled in host-only and gadget-only (as well as
DRD) configurations
. UVC now enables streaming endpoint based on negotiated speed
. isp1301 now implements the PHY API properly
. configfs-based interface for gadget drivers which will lead to
the removal of all code which just combines functions together
to build functional gadget drivers.
. f_serial and f_obex were converted to new configfs interface while
maintaining old interface around.
- non-critical fixes:
. UVC gadget driver got fixes for Endpoint usage and stream calculation
. ab8500-usb fixed unbalanced clock and regulator API usage
. twl4030-usb got a fix for when OMAP3 is booted with cable connected
. fusb300_udc got a fix for DMA usage
. UVC got fixes for two assertions of the USB Video Class Compliance
specification revision 1.1
. build warning issues caused by recent addition of __must_check to
regulator API
These are all changes which deserve a mention, all other changes are related
to these one or minor spelling fixes and other similar tasks.

This reverts commit 6ab317419c.
The commit [6ab317419c: ALSA: hda - Allow power_save_controller option
override DCAPS] changed the behavior of power_save_controller so that
it can override the driver capability. This assumed that this option
is rarely changed dynamically unlike power_save option. Too naive.
It turned out that the user-space power-management tool tries to set
power_save_controller option to 1 together with power_save option
without knowing what's actually doing. This enabled forcibly the
runtime PM of the controller, which is known to be broken om many
chips thus disabled as default.
So, the only sane fix is to revert this commit again. It was intended
to ease debugging/testing for runtime PM enablement, but obviously we
need another way for it.

Userspace applications need to know the maximum supported message
size.
The cdc-wdm driver translates between a character device stream
and a message based protocol. Each message is transported as a
usb control message with no further encapsulation or syncronization.
Each read or write on the character device should translate to
exactly one usb control message to ensure that message boundaries
are kept intact. That means that the userspace application must
know the maximum message size supported by the device and driver,
making this size a vital part of the cdc-wdm character device API.
CDC WDM and CDC MBIM functions export the maximum supported
message size through CDC functional descriptors. The cdc-wdm and
cdc_mbim drivers will parse these descriptors and use the value
chosen by the device. The only current way for a userspace
application to retrive the value is by duplicating the descriptor
parsing. This is an unnecessary complex task, and application
writers are likely to postpone it, using a fixed value and adding
a "todo" item.
QMI functions have no way to tell the host what message size they
support. The qmi_wwan driver use a fixed value based on protocol
recommendations and observed device behaviour. Userspace
applications must know and hard code the same value. This scheme
will break if we ever encounter a QMI device needing a device
specific message size quirk. We are currently unable to support
such a device because using a non default size would break the
implicit userspace API.
The message size is currently a hidden attribute of the cdc-wdm
userspace API. Retrieving it is unnecessarily complex, increasing
the possibility of drivers and applications using different limits.
The resulting errors are hard to debug, and can only be replicated
on identical hardware.
Exporting the maximum message size from the driver simplifies the
task for the userspace application, and creates a unified
information source independent of device and function class. It also
serves to document that the message size is part of the cdc-wdm
userspace API.
This proposed API extension has been presented for the authors of
userspace applications and libraries using the current API: libmbim,
libqmi, uqmi, oFono and ModemManager. The replies were:
Aleksander Morgado:
"We do really need max message size for MBIM; and as you say, it may be
good to have the max message size info also for QMI, so the new ioctl
seems a good addition. So +1 from my side, for what it's worth."
Dan Williams:
"Yeah, +1 here. I'd prefer the sysfs file, but the fact that that
doesn't work for fd passing pretty much kills it."
No negative replies are so far received.

====================
The following patchset contains 7 Netfilter/IPVS fixes for 3.9-rc, they are:
* Restrict IPv6 stateless NPT targets to the mangle table. Many users are
complaining that this target does not work in the nat table, which is the
wrong table for it, from Florian Westphal.
* Fix possible use before initialization in the netns init path of several
conntrack protocol trackers (introduced recently while improving conntrack
netns support), from Gao Feng.
* Fix incorrect initialization of copy_range in nfnetlink_queue, spotted
by Eric Dumazet during the NFWS2013, patch from myself.
* Fix wrong calculation of next SCTP chunk in IPVS, from Julian Anastasov.
* Remove rcu_read_lock section in IPVS while calling ipv4_update_pmtu
not required anymore after change introduced in 3.7, again from Julian.
* Fix SYN looping in IPVS state sync if the backup is used a real server
in DR/TUN modes, this required a new /proc entry to disable the director
function when acting as backup, also from Julian.
* Remove leftover IP_NF_QUEUE Kconfig after ip_queue removal, noted by
Paul Bolle.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Dmitry Akindinov is reporting for a problem where SYNs are looping
between the master and backup server when the backup server is used as
real server in DR mode and has IPVS rules to function as director.
Even when the backup function is enabled we continue to forward
traffic and schedule new connections when the current master is using
the backup server as real server. While this is not a problem for NAT,
for DR and TUN method the backup server can not determine if a request
comes from client or from director.
To avoid such loops add new sysctl flag backup_only. It can be needed
for DR/TUN setups that do not need backup and director function at the
same time. When the backup function is enabled we stop any forwarding
and pass the traffic to the local stack (real server mode). The flag
disables the director function when the backup function is enabled.
For setups that enable backup function for some virtual services and
director function for other virtual services there should be another
more complex solution to support DR/TUN mode, may be to assign
per-virtual service syncid value, so that we can differentiate the
requests.

The ab8500 device is a child of the prcmu device, which is a memory mapped
bus device, whose children are addressable using physical memory addresses,
not using mailboxes, so a mailbox number in the ab8500 node cannot be
parsed by DT. Nothing uses this number, since it was only introduced
as part of the failed attempt to clean up prcmu mailbox handling, and
we can simply remove it.

Meta core internal interrupts (from HWSTATMETA and friends) are vectored
onto the TR1 core trigger for the current thread. This is demultiplexed
in irq-metag.c to individual Linux IRQs for each internal interrupt.
External SoC interrupts (from HWSTATEXT and friends) are vectored onto
the TR2 core trigger for the current thread. This is demultiplexed in
irq-metag-ext.c to individual Linux IRQs for each external SoC interrupt.
The external irqchip has devicetree bindings for configuring the number
of irq banks and the type of masking available.

an SSD to be used as a cache in front of a slower device. Cache
tuning is delegated to interchangeable policy modules so these can
be developed independently of the mechanics needed to shuffle the
data around.
Other than that, kcopyd users acquire a throttling parameter, ioctl
buffer usage gets streamlined, more mempool reliance is reduced
and there are a few other bug fixes and tidy-ups.
