2013-05-16USB: serial: add generic wait_until_sent implementationJohan Hovold
Add generic wait_until_sent implementation which polls for empty hardware buffers using the new port-operation tx_empty. The generic implementation will be used for all sub-drivers that implement tx_empty but does not define wait_until_sent.

2013-05-08usbnet: allow status interrupt URB to always be activeDan Williams
Some drivers (sierra_net) need the status interrupt URB active even when the device is closed, because they receive custom indications from firmware. Add functions to refcount the status interrupt URB submit/kill operation so that sub-drivers and the generic driver don't fight over whether the status interrupt URB is active or not. A sub-driver can call usbnet_status_start() at any time, but the URB is only submitted the first time the function is called. Likewise, when the sub-driver is done with the URB, it calls usbnet_status_stop() but the URB is only killed when all users have stopped it. The URB is still killed and re-submitted for suspend/resume, as before, with the same refcount it had at suspend.

2013-04-23usb: phy: tegra: don't call into tegra-ehci directlyArnd Bergmann
Both phy-tegra-usb.c and ehci-tegra.c export symbols used by the other one, which does not work if one of them or both are loadable modules, resulting in an error like: drivers/built-in.o: In function `utmi_phy_clk_disable': drivers/usb/phy/phy-tegra-usb.c:302: undefined reference to `tegra_ehci_set_phcd' drivers/built-in.o: In function `utmi_phy_clk_enable': drivers/usb/phy/phy-tegra-usb.c:324: undefined reference to `tegra_ehci_set_phcd' drivers/built-in.o: In function `utmi_phy_power_on': drivers/usb/phy/phy-tegra-usb.c:447: undefined reference to `tegra_ehci_set_pts' This turns the interface into a one-way dependency by letting the tegra ehci driver pass two function pointers for callbacks that need to be called by the phy driver.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v3.10 A bunch of changes here, the most interesting one subsystem wise being Morimoto-san's work to create snd_soc_component which doesn't do much for now but will be pretty important going forwards: - Add a new component object type which will form the basis of moving to a more generic handling of SoC and off-SoC components, contributed by Kuninori Morimoto. - A fairly large set of cleanups for the dmaengine integration from Lars-Peter Clausen, starting to move towards being able to have a generic driver based on the library. - Performance optimisations to DAPM from Ryo Tsutsui. - Support for mixer control sharing in DAPM from Stephen Warren. - Multiplatform ARM cleanups from Arnd Bergmann. - New CODEC drivers for AK5385 and TAS5086 from Daniel Mack.
2013-04-11usbnet: handle link changeMing Lei
The link change is detected via the interrupt pipe, and bulk pipes are responsible for transfering packets, so it is reasonable to stop bulk transfer after link is reported as off. Two adavantages may be obtained with stopping bulk transfer after link becomes off: - USB bus bandwidth is saved(USB bus is shared bus except for USB3.0), for example, lots of 'IN' token packets and 'NYET' handshake packets is transfered on 2.0 bus. - probabaly power might be saved for usb host controller since cancelling bulk transfer may disable the asynchronous schedule of host controller. With this patch, when link becomes off, about ~10% performance boost can be found on bulk transfer of anther usb device which is attached to same bus with the usbnet device, see below test on next-20130410: - read from usb mass storage(Sandisk Extreme USB 3.0) on pandaboard with below command after unplugging ethernet cable: dd if=/dev/sda iflag=direct of=/dev/null bs=1M count=800 - without the patch 1, 838860800 bytes (839 MB) copied, 36.2216 s, 23.2 MB/s 2, 838860800 bytes (839 MB) copied, 35.8368 s, 23.4 MB/s 3, 838860800 bytes (839 MB) copied, 35.823 s, 23.4 MB/s 4, 838860800 bytes (839 MB) copied, 35.937 s, 23.3 MB/s 5, 838860800 bytes (839 MB) copied, 35.7365 s, 23.5 MB/s average: 23.6MB/s - with the patch 1, 838860800 bytes (839 MB) copied, 32.3817 s, 25.9 MB/s 2, 838860800 bytes (839 MB) copied, 31.7389 s, 26.4 MB/s 3, 838860800 bytes (839 MB) copied, 32.438 s, 25.9 MB/s 4, 838860800 bytes (839 MB) copied, 32.5492 s, 25.8 MB/s 5, 838860800 bytes (839 MB) copied, 31.6178 s, 26.5 MB/s average: 26.1MB/s Signed-off-by: Ming Lei <ming.lei@canonical.com> Signed-off-by: David S.

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.

The name of available UDCs can be obtained from /sys/class/udc/ v4…v5 - string rework. This will add a strings folder incl. language code like strings/409/manufacturer as suggested by Alan. - rebased ontop reworked functions.c which has usb_function_instance which is used prior after "mkdir acm.instance" and can be directly used for configuration via configfs. v3…v4 - moved functions from the root folde down to the gadget as suggested by Michał - configs have now their own configs folder as suggested by Michał. The folder is still name.bConfigurationValue where name becomes the sConfiguration. Is this usefull should we just stilc configs/bConfigurationValue/ ? - added configfs support to the ACM function. The port_num attribute is exported by f_acm. An argument has been added to the USB alloc function to distinguish between "old" (use facm_configure() to configure and configfs interface (expose a config_node). The port_num is currently a dumb counter. It will require some function re-work to make it work. scheduled for v5: - sym linking function into config. v2…v3 - replaced one ifndef by ifdef as suggested by Micahał - strstr()/strchr() function_make as suggested by Micahł - replace [iSerialNumber|iProduct|iManufacturer] with [sSerialNumber|sProduct|sManufacturer] as suggested by Alan - added creation of config descriptors v1…v2 - moved gadgets from configfs' root directory into /udcs/ within our "usb_gadget" folder. Requested by Andrzej & Michał - use a dot as a delimiter between function's name and its instance's name as suggested by Michał - renamed all config_item_type, configfs_group_operations, make_group, drop_item as suggested by suggested by Andrzej to remain consisten within this file and within other configfs users - Since configfs.c and functions.c are now part of the udc-core module, the module itself is now called udc. Also added a tiny ifdef around init code becuase udc-core is subsys init and this is too early for configfs in the built-in case. In the module case, we can only have one init function.

2013-03-28USB: remove CONFIG_USB_SUSPEND optionAlan Stern
This patch (as1675) removes the CONFIG_USB_SUSPEND option, essentially replacing it everywhere with CONFIG_PM_RUNTIME (except for one place in hub.c, where it is replaced with CONFIG_PM because the code needs to be used in both runtime and system PM). The net result is code shrinkage and simplification. There's very little point in keeping CONFIG_USB_SUSPEND because almost everybody enables it. The few that don't will find that the usbcore module has gotten somewhat bigger and they will have to take active measures if they want to prevent hubs from being runtime suspended.

2013-03-25USB: serial: add generic TIOCMIWAIT implementationJohan Hovold
Add generic TIOCMIWAIT implementation which correctly handles hangup, USB-device disconnect, does not rely on the deprecated sleep_on functions and hence does not suffer from the races currently affecting several usb-serial drivers. This makes it much easier to add TIOCMIWAIT support to subdrivers as the tricky details related to hangup and disconnect (e.g. atomicity, that the private port data may have been freed when woken up, and waking up processes at disconnect) have been handled once and for all. To add support to a subdriver, simply set the tiocmiwait-port-operation field, update the port icount fields and wake up any process sleeping on the tty-port modem-status-change wait queue on changes. Note that the tty-port initialised flag can be used to detect disconnected as the port will be hung up as part of disconnect (and cannot be reactivated due to the disconnected flag). However, as the tty-port implementation currently wakes up processes before calling port shutdown, the tty-hupping flag must also be checked to detect hangup for now.

2013-03-25USB: cdc-wdm: implement IOCTL_WDM_MAX_COMMANDBjørn Mork
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."

2013-03-25usb: add find_raw_port_number callback to struct hc_driver()Lan Tianyu
xhci driver divides the root hub into two logical hubs which work respectively for usb 2.0 and usb 3.0 devices. They are independent devices in the usb core. But in the ACPI table, it's one device node and all usb2.0 and usb3.0 ports are under it. Binding usb port with its acpi node needs the raw port number which is reflected in the xhci extended capabilities table. This patch is to add find_raw_port_number callback to struct hc_driver(), fill it with xhci_find_raw_port_number() which will return raw port number and add a wrap usb_hcd_find_raw_port_number(). Otherwise, refactor xhci_find_real_port_number(). Using xhci_find_raw_port_number() to get real index in the HW port status registers instead of scanning through the xHCI roothub port array. This can help to speed up. All addresses in xhci->usb2_ports and xhci->usb3_ports array are kown good ports and don't include following bad ports in the extended capabilities talbe. (1) root port that doesn't have an entry (2) root port with unknown speed (3) root port that is listed twice and with different speeds. So xhci_find_raw_port_number() will only return port num of good ones and never touch bad ports above.

commit bd329e1 ("net: cdc_ncm: do not bind to NCM compatible MBIM devices") introduced a new policy, preferring MBIM for dual NCM/MBIM functions if the cdc_mbim driver was enabled. This caused a regression for users wanting to use NCM. Devices implementing NCM backwards compatibility according to section 3.2 of the MBIM v1.0 specification allow either NCM or MBIM on a single USB function, using different altsettings. The cdc_ncm and cdc_mbim drivers will both probe such functions, and must agree on a common policy for selecting either MBIM or NCM. Until now, this policy has been set at build time based on CONFIG_USB_NET_CDC_MBIM. Use a module parameter to set the system policy at runtime, allowing the user to prefer NCM on systems with the cdc_mbim driver.

From Emmanuel Grumbach. 2) Work limiting code in brcmsmac wifi driver can clear tx status without processing the event. From Arend van Spriel. 3) rtlwifi USB driver processes wrong SKB, fix from Larry Finger. 4) l2tp tunnel delete can race with close, fix from Tom Parkin. 5) pktgen_add_device() failures are not checked at all, fix from Cong Wang. 6) Fix unintentional removal of carrier off from tun_detach(), otherwise we confuse userspace, from Michael S. Tsirkin. 7) Don't leak socket reference counts and ubufs in vhost-net driver, from Jason Wang. 8) vmxnet3 driver gets it's initial carrier state wrong, fix from Neil Horman. 9) Protect against USB networking devices which spam the host with 0 length frames, from Bjørn Mork. 10) Prevent neighbour overflows in ipv6 for locally destined routes, from Marcelo Ricardo. This is the best short-term fix for this, a longer term fix has been implemented in net-next. 11) L2TP uses ipv4 datagram routines in it's ipv6 code, whoops. This mistake is largely because the ipv6 functions don't even have some kind of prefix in their names to suggest they are ipv6 specific. From Tom Parkin. 12) Check SYN packet drops properly in tcp_rcv_fastopen_synack(), from Yuchung Cheng. 13) Fix races and TX skb freeing bugs in via-rhine's NAPI support, from Francois Romieu and your's truly. 14) Fix infinite loops and divides by zero in TCP congestion window handling, from Eric Dumazet, Neal Cardwell, and Ilpo Järvinen. 15) AF_PACKET tx ring handling can leak kernel memory to userspace, fix from Phil Sutter. 16) Fix error handling in ipv6 GRE tunnel transmit, from Tommi Rantala. 17) Protect XEN netback driver against hostile frontend putting garbage into the rings, don't leak pages in TX GOP checking, and add proper resource releasing in error path of xen_netbk_get_requests(). From Ian Campbell. 18) SCTP authentication keys should be cleared out and released with kzfree(), from Daniel Borkmann. 19) L2TP is a bit too clever trying to maintain skb->truesize, and ends up corrupting socket memory accounting to the point where packet sending is halted indefinitely. Just remove the adjustments entirely, they aren't really needed. From Eric Dumazet. 20) ATM Iphase driver uses a data type with the same name as the S390 headers, rename to fix the build. From Heiko Carstens. 21) Fix a typo in copying the inner network header offset from one SKB to another, from Pravin B Shelar. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (56 commits) net: sctp: sctp_endpoint_free: zero out secret key data net: sctp: sctp_setsockopt_auth_key: use kzfree instead of kfree atm/iphase: rename fregt_t -> ffreg_t net: usb: fix regression from FLAG_NOARP code l2tp: dont play with skb->truesize net: sctp: sctp_auth_key_put: use kzfree instead of kfree netback: correct netbk_tx_err to handle wrap around. xen/netback: free already allocated memory on failure in xen_netbk_get_requests xen/netback: don't leak pages on failure in xen_netbk_tx_check_gop. xen/netback: shutdown the ring if it contains garbage. net: qmi_wwan: add more Huawei devices, including E320 net: cdc_ncm: add another Huawei vendor specific device ipv6/ip6_gre: fix error case handling in ip6gre_tunnel_xmit() tcp: fix for zero packets_in_flight was too broad brcmsmac: rework of mac80211 .flush() callback operation ssb: unregister gpios before unloading ssb bcma: unregister gpios before unloading bcma rtlwifi: Fix scheduling while atomic bug net: usbnet: fix tx_dropped statistics tcp: ipv6: Update MIB counters for drops ...

2013-02-08net: usb: fix regression from FLAG_NOARP codeLucas Stach
In commit 6509141f9c2ba74df6cc72ec35cd1865276ae3a4 ("usbnet: add new flag FLAG_NOARP for usb net devices"), the newly added flag NOARP was using an already defined value, which broke drivers using flag MULTI_PACKET.
