2013-02-19HID: add ThingM blink(1) USB RGB LED supportVivien Didelot
The ThingM blink(1) is an open source hardware USB RGB LED. It contains an internal EEPROM, allowing to configure up to 12 light patterns. A light pattern is a RGB color plus a fade time. This driver registers a LED class instance with additional sysfs attributes to support basic functions such as setting RGB colors, fade and playing. Other functions are still accessible through the hidraw interface. At this time, the only documentation for the device is the firmware source code from ThingM, plus a few schematics. They are available at: https://github.com/todbot/blink1 This patch is version 3. It updates the name of the source file, the driver and the led sysfs entry, according to comments from Jiri Kosina and Simon Wood.

2013-02-12pstore: Create a convenient mount point for pstoreJosh Boyer
Using /dev/pstore as a mount point for the pstore filesystem is slightly awkward. We don't normally mount filesystems in /dev/ and the /dev/pstore file isn't created automatically by anything. While this method will still work, we can create a persistent mount point in sysfs. This will put pstore on par with things like cgroups and efivarfs.

2013-02-06ima: add policy support for file system uuidDmitry Kasatkin
The IMA policy permits specifying rules to enable or disable measurement/appraisal/audit based on the file system magic number. If, for example, the policy contains an ext4 measurement rule, the rule is enabled for all ext4 partitions. Sometimes it might be necessary to enable measurement/appraisal/audit only for one partition and disable it for another partition of the same type. With the existing IMA policy syntax, this can not be done. This patch provides support for IMA policy rules to specify the file system by its UUID (eg. fsuuid=397449cd-687d-4145-8698-7fed4a3e0363). For partitions not being appraised, it might be a good idea to mount file systems with the 'noexec' option to prevent executing non-verified binaries.

2013-01-25ACPI / PM: Expose lists of device power resources to user spaceRafael J. Wysocki
Since ACPI power resources are going to be used more extensively on new hardware platforms, it is necessary to allow user space (powertop in particular) to look at the lists of power resources corresponding to different power states of devices for diagnostics and control purposes. For this reason, for each power state of an ACPI device node using power resources create a special attribute group under the device node's directory in sysfs containing links to sysfs directories representing the power resources in that list. The names of the new attribute groups are "power_resources_<state>", where <state> is the state name i.e. "D0", "D1", "D2", or "D3hot". Signed-off-by: Rafael J.

The Technologic Systems TS-5500 is an x86-based (AMD Elan SC520) single board computer. This driver registers most of its devices and exposes sysfs attributes for information such as jumpers' state or presence of some of its options. This driver currently registers the TS-5500 platform, its on-board LED, 2 pin blocks (GPIO) and its analog/digital converter. It can be extended to support other Technologic Systems products, such as the TS-5600.

With the addition of the new kernel module syscall, which defines two arguments - a file descriptor to the kernel module and a pointer to a NULL terminated string of module arguments - it is now possible to measure and appraise kernel modules like any other file on the file system. This patch adds support to measure and appraise kernel modules in an extensible and consistent manner. To support filesystems without extended attribute support, additional patches could pass the signature as the first parameter.

Biederman. 4) tuntap/virtio-net multiqueue support by Jason Wang. 5) Support for checksum offload of encapsulated packets (basically, tunneled traffic can still be checksummed by HW). From Joseph Gasparakis. 6) Allow BPF filter access to VLAN tags, from Eric Dumazet and Daniel Borkmann. 7) Bridge port parameters over netlink and BPDU blocking support from Stephen Hemminger. 8) Improve data access patterns during inet socket demux by rearranging socket layout, from Eric Dumazet. 9) TIPC protocol updates and cleanups from Ying Xue, Paul Gortmaker, and Jon Maloy. 10) Update TCP socket hash sizing to be more in line with current day realities.
