2018-07-04USB: serial: ch341: fix type promotion bug in ch341_control_in()Dan Carpenter
The "r" variable is an int and "bufsize" is an unsigned int so the comparison is type promoted to unsigned. If usb_control_msg() returns a negative that is treated as a high positive value and the error handling doesn't work.

2018-06-26USB: serial: usb_wwan: use irqsave() in USB's complete callbackJohn Ogness
The USB completion callback does not disable interrupts while acquiring the lock. We want to remove the local_irq_disable() invocation from __usb_hcd_giveback_urb() and therefore it is required for the callback handler to disable the interrupts while acquiring the lock. The callback may be invoked either in IRQ or BH context depending on the USB host controller. Use the _irqsave() variant of the locking primitives.

2018-06-12treewide: kmalloc() -> kmalloc_array()Kees Cook
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2018-03-19USB: serial: option: reimplement interface maskingJohan Hovold
Reimplement interface masking using device flags stored directly in the device-id table. This will make it easier to add and maintain device-id entries by using a more compact and readable notation compared to the current implementation (which manages pairs of masks in separate blacklist structs). Two convenience macros are used to flag an interface as either reserved or as not supporting modem-control requests: { USB_DEVICE(TELIT_VENDOR_ID, TELIT_PRODUCT_ME910_DUAL_MODEM), .driver_info = NCTRL(0) | RSVD(3) }, For now, we limit the highest maskable interface number to seven, which allows for (up to 16) additional device flags to be added later should need arise. Note that this will likely need to be backported to stable in order to make future device-id backports more manageable.

2018-02-15USB: serial: option: Add support for Quectel EP06Kristian Evensen
The Quectel EP06 is a Cat. 6 LTE modem, and the interface mapping is as follows: 0: Diag 1: NMEA 2: AT 3: Modem Interface 4 is QMI and interface 5 is ADB, so they are blacklisted. This patch should also be considered for -stable. The QMI-patch for this modem is already in the -stable-queue. v1->v2: * Updated commit prefix (thanks Johan Hovold) * Updated commit message slightly.

The majority of the work here is in the firmware subsystem, with reworks to try to attempt to make the code easier to handle in the long run, but no functional change. There's also some tree-wide sysfs attribute fixups with lots of acks from the various subsystem maintainers, as well as a handful of other normal fixes and changes. And finally, some license cleanups for the driver core and sysfs code.

2018-01-24USB: move many drivers to use DEVICE_ATTR_WOGreg Kroah-Hartman
Instead of "open coding" a DEVICE_ATTR() define, use the DEVICE_ATTR_WO() macro instead, which does everything properly instead. This does require a few static functions to be renamed to work properly, but thanks to a script from Joe Perches, this was easily done.
