2012-01-08perf report: Fix --stdio output alignment when --showcpuutilization usedNamhyung Kim
Current perf report output is broken if --showcpuutilization is used. Combination with -n and/or --show-total-period make things worse.

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>

2012-01-07via-rhine: move work from irq handler to softirq and beyond.Francois Romieu
- Tx processing is moved from the irq handler to NAPI poll - link events and obscure event processing is moved to its proper work queue Locking rules undergo some changes through the driver. - the driver offers the usual lock-free Tx path - besides the IRQ handler, the link event task schedules the napi handler. The driver thus adds some internal locking to prevent a loop when both must be disabled. - the reset task keeps being scheduled from the Tx watchdog handler, thus with implicit Tx queue disabling. It does not need to care about irq, only napi softirq and competing task. - it is not worth to add a dedicated lock between {g, s}et_wol and rhine_shutdown. It should not hurt no narrow it down a bit though. - rhine_reset_task must keep its huge spin_lock_bh protected section due to : - races for the CAM registers (see rhine_vlan_rx_{add, kill}_vid) - implicit use of napi_enable (see init_registers) - use of the same lock for stats read / update exclusion between napi rx processing and rhine_get_stats - rhine_resume requires a softirq disabled section for the same reason as rhine_reset_task - {free, request}_irq have been replaced with IntrEnable actions in rhine_{suspend, resume}. It is hidden behind init_registers for the latter. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com>
