2012-01-08C6X: fix timer64 initializationMark Salter
Some SoCs have a timer block enable controlled through the DSCR registers. There is a problem in the timer64 driver initialization where the code accesses a timer register to get the divisor used to calculate timer clock rate. If the timer block has not been enabled when this register read takes place, an exception is generated. This patch makes sure that the timer block is enabled before accessing the registers.

2012-01-08ALSA: usb-audio: fix possible hang and overflow in ↵Xi Wang
parse_uac2_sample_rate_range() A malicious USB device may feed in carefully crafted min/max/res values, so that the inner loop in parse_uac2_sample_rate_range() could run for a long time or even never terminate, e.g., given max = INT_MAX. Also nr_rates could be a large integer, which causes an integer overflow in the subsequent call to kmalloc() in parse_audio_format_rates_v2(). Thus, kmalloc() would allocate a smaller buffer than expected, leading to a memory corruption. To exploit the two vulnerabilities, an attacker needs physical access to the machine to plug in a malicious USB device. This patch makes two changes. 1) The type of "rate" is changed to unsigned int, so that the loop could stop once "rate" is larger than INT_MAX. 2) Limit nr_rates to 1024.

When using remake, which is based on gnumake, if you invoke an example build as shown below, the build will become silent due to the top level make file incorrectly guessing that the end user wants a silent build because an argument that contained an "s" was used. Here are two examples one with remake and one with straight gnumake. remake --no-extended-errors make --warn-undefined-variables Fix up the top level Makefile to use filter to parse the options that mean silent instead of findstring catching other random arguments containing an "s".

2012-01-08hid-input: add support for HID devices reporting Battery StrengthDaniel Nicoletti
I've sent an email earlier asking for help with a GetFeature code, and now I have a second patch on top of Jeremy's to provide the battery functionality for devices that support reporting it. If I understood correctly when talking to Jeremy he said his device never actually reported the status as an input event (sorry if I didn't understand it correctly), and after reading HID specs I believe it's really because it was meant to be probed, I have an Apple Keyboard and Magic Trackpad both bluetooth batteries operated, so using PacketLogger I saw that Mac OSX always ask the battery status using the so called GetFeature. What my patch does is basically: - store the report id that matches the battery_strength - setup the battery if 0x6.0x20 is found, even if that is reported as a feature (as it was meant to be but only the MagicTrackpad does) - when upower or someone access /sys/class/power_supply/hid-*/capacity it will probe the device and return it's status. It works great for both devices, but I have two concerns: - the report_features function has a duplicated code - it would be nice if it was possible for specific drivers to provide their own probe as there might be some strange devices... (but maybe it's already possible) I've talked to the upower dev and he fixed it to be able to show the right percentage. Here how the uevent file (in /sys/class/power_supply/hid-*/) looks like: POWER_SUPPLY_NAME=hid-00:22:41:D9:18:E7-battery POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_ONLINE=1 POWER_SUPPLY_CAPACITY=66 POWER_SUPPLY_MODEL_NAME=MacAdmin’s keyboard POWER_SUPPLY_STATUS=Discharging POWER_SUPPLY_NAME=hid-70:CD:60:F5:FF:3F-battery POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_ONLINE=1 POWER_SUPPLY_CAPACITY=62 POWER_SUPPLY_MODEL_NAME=nexx’s Trackpad POWER_SUPPLY_STATUS=Discharging Signed-off-by: Daniel Nicoletti <dantti12@gmail.com>
