2013-03-25USB: cdc-wdm: implement IOCTL_WDM_MAX_COMMANDBjørn Mork1-0/+1
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.

2013-02-01wanrouter: completely decouple obsolete code from kernel.Paul Gortmaker1-1/+1
The original suggestion to delete wanrouter started earlier with the mainline commit f0d1b3c2bcc5de8a17af5f2274f7fcde8292b5fc ("net/wanrouter: Deprecate and schedule for removal") in May 2012. More importantly, Dan Carpenter found[1] that the driver had a fundamental breakage introduced back in 2008, with commit 7be6065b39c3 ("netdevice wanrouter: Convert directly reference of netdev->priv"). So we know with certainty that the code hasn't been used by anyone willing to at least take the effort to send an e-mail report of breakage for at least 4 years. This commit does a decouple of the wanrouter subsystem, by going after the Makefile/Kconfig and similar files, so that these mainline files that we are keeping do not have the big wanrouter file/driver deletion commit tied into their history. Once this commit is in place, we then can remove the obsolete cyclomx drivers and similar that have a dependency on CONFIG_WAN_ROUTER_DRIVERS.

2012-07-31vfio: VFIO coreAlex Williamson1-0/+1
VFIO is a secure user level driver for use with both virtual machines and user level drivers. VFIO makes use of IOMMU groups to ensure the isolation of devices in use, allowing unprivileged user access. It's intended that VFIO will replace KVM device assignment and UIO drivers (in cases where the target platform includes a sufficiently capable IOMMU). New in this version of VFIO is support for IOMMU groups managed through the IOMMU core as well as a rework of the API, removing the group merge interface. We now go back to a model more similar to original VFIO with UIOMMU support where the file descriptor obtained from /dev/vfio/vfio allows access to the IOMMU, but only after a group is added, avoiding the previous privilege issues with this type of model. IOMMU support is also now fully modular as IOMMUs have vastly different interface requirements on different platforms. VFIO users are able to query and initialize the IOMMU model of their choice. Please see the follow-on Documentation commit for further description and usage example. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

The framework is currently being used for some people and we would like to see it integrated into the kernel for 3.3. There is no HW controller drivers in this pull, but some people have already some of them pending which they would like to push as soon as this integrated. I am also working on the acceptance for an TI OMAP one, based on a compatible legacy version of the interface called SSI." Ok, so it didn't get into 3.3, but here it is pulled into 3.4.

2012-03-05ppp: Move ioctl definitions from if_ppp.h to new ppp-ioctl.hPaul Mackerras1-1/+1
This moves the definitions of the ioctls, constants and structures relating to the ppp_generic interface to userspace out from if_ppp.h to a new file, ppp-ioctl.h. The new file has my copyright since I designed and implemented the ppp_generic interface in the late 1990s. None of the contents of this file comes from the original if_ppp.h published by Carnegie Mellon University. Of the remainder of if_ppp.h, only the PPP_MTU definition was being used, and this replaces the uses of it with PPP_MRU (which is identical). Therefore, this replaces the entire file with the single line #include <linux/ppp-ioctl.h> which clearly doesn't contain any CMU code. Thus I have removed the CMU copyright notice with its problematic advertising clause, and in fact since it's only one trivial line I have not added any other copyright notice.

2011-05-25mmc: core: Add mmc CMD+ACMD passthrough ioctlJohn Calixto1-0/+1
Allows appropriately-privileged applications to send CMD (normal) and ACMD (application-specific; preceded with CMD55) commands to cards/devices on the mmc bus. This is primarily useful for enabling the security functionality built in to every SD card. It can also be used as a generic passthrough (e.g. to enable virtual machines to control mmc bus devices directly). However, this use case has not been tested rigorously. Generic passthrough testing was only conducted for a few non-security opcodes to prove the feasibility of the passthrough. Since any opcode can be sent using this passthrough, it is very possible to render the card/device unusable. Applications that use this ioctl must have CAP_SYS_RAWIO. Security commands tested on TI PCIxx12 (SDHCI), Sigma Designs SMP8652 SoC, TI OMAP3621/OMAP3630 SoC, Samsung S5PC110 SoC, Qualcomm MSM7200A SoC.

2010-10-05smbfs: move to drivers/stagingArnd Bergmann1-1/+1
smbfs has been scheduled for removal in 2.6.27, so maybe we can now move it to drivers/staging on the way out. smbfs still uses the big kernel lock and nobody is going to fix that, so we should be getting rid of it soon. This removes the 32 bit compat mount and ioctl handling code, which is implemented in common fs code, and moves all smbfs related files into drivers/staging/smbfs.

2010-08-04Documentation: update broken web addresses.Justin P. Mattock1-5/+5
Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.
