git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus Felipe writes: usb: fixes for v3.9-rc4 udc-core learned that it shouldn't use invalid pointers when unloading a gadget driver. net2272 and net2280 got a fix for a regression caused by the udc_start/udc_stop conversion. We're defining a static inline no-op for otg_ulpi_create() to prevent build errors when that driver isn't enabled. FunctionFS got a fix for an off-by-one error when binding and unbinding instances of FunctionFS. MUSB learned that it shouldn't try to unmap buffers which weren't previously mapped. f_rndis got a fix for a possible NULL pointer dereference in a debugging message code. MUSB's DA8xx glue layer got a build fix due to a typo.
2013-03-21usb: gadget: net2272: finally convert "CONFIG_USB_GADGET_NET2272_DMA"Paul Bolle
The Kconfig symbol USB_GADGET_NET2272_DMA was renamed to USB_NET2272_DMA in commit 193ab2a6070039e7ee2b9b9bebea754a7c52fd1b ("usb: gadget: allow multiple gadgets to be built"). That commit did not convert the only occurrence of the corresponding Kconfig macro. Convert that macro now. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-03-20usb: gadget: f_rndis: Avoid to use ERROR macro if cdev can be nullTruls Bengtsson
The udc_irq service runs the isr_tr_complete_handler which in turn "nukes" the endpoints, including a call to rndis_response_complete, if appropriate. If the rndis_msg_parser fails here, an error will be printed using a dev_err call (through the ERROR() macro). However, if the usb cable was just disconnected the device (cdev) might not be available and will be null. Since the dev_err macro will dereference the cdev pointer we get a null pointer exception.

This patch (as1667) removes an incorrect driver->unbind() call from the net2280 driver.

2013-03-20usb: gadget: udc-core: fix a regression during gadget driver unbindingAlan Stern
This patch (as1666) fixes a regression in the UDC core. The core takes care of unbinding gadget drivers, and it does the unbinding before telling the UDC driver to turn off the controller hardware. When the call to the udc_stop callback is made, the gadget no longer has a driver. The callback routine should not be invoked with a pointer to the old driver; doing so can cause problems (such as use-after-free accesses in net2280). This patch should be applied, with appropriate context changes, to all the stable kernels going back to 3.1.

2013-03-04fs: Limit sys_mount to only request filesystem modules.Eric W. Biederman
Modify the request_module to prefix the file system type with "fs-" and add aliases to all of the filesystems that can be built as modules to match. A common practice is to build all of the kernel code and leave code that is not commonly needed as modules, with the result that many users are exposed to any bug anywhere in the kernel. Looking for filesystems with a fs- prefix limits the pool of possible modules that can be loaded by mount to just filesystems trivially making things safer with no real cost. Using aliases means user space can control the policy of which filesystem modules are auto-loaded by editing /etc/modprobe.d/*.conf with blacklist and alias directives. Allowing simple, safe, well understood work-arounds to known problematic software. This also addresses a rare but unfortunate problem where the filesystem name is not the same as it's module name and module auto-loading would not work. While writing this patch I saw a handful of such cases. The most significant being autofs that lives in the module autofs4. This is relevant to user namespaces because we can reach the request module in get_fs_type() without having any special permissions, and people get uncomfortable when a user specified string (in this case the filesystem type) goes all of the way to request_module. After having looked at this issue I don't think there is any particular reason to perform any filtering or permission checks beyond making it clear in the module request that we want a filesystem module. The common pattern in the kernel is to call request_module() without regards to the users permissions. In general all a filesystem module does once loaded is call register_filesystem() and go to sleep. Which means there is not much attack surface exposed by loading a filesytem module unless the filesystem is mounted. In a user namespace filesystems are not mounted unless .fs_flags = FS_USERNS_MOUNT, which most filesystems do not set today.
