      tcp: randomize timestamps on syncookies · 84b114b9
      Eric Dumazet authored
      Whole point of randomization was to hide server uptime, but an attacker
      can simply start a syn flood and TCP generates 'old style' timestamps,
      directly revealing server jiffies value.
      
      Also, TSval sent by the server to a particular remote address vary
      depending on syncookies being sent or not, potentially triggering PAWS
      drops for innocent clients.
      
      Lets implement proper randomization, including for SYNcookies.
      
      Also we do not need to export sysctl_tcp_timestamps, since it is not
      used from a module.
      
      In v2, I added Florian feedback and contribution, adding tsoff to
      tcp_get_cookie_sock().
      
      v3 removed one unused variable in tcp_v4_connect() as Florian spotted.
      
      Fixes: 95a22cae ("tcp: randomize tcp timestamp offsets for each connection")

       "Here is the big USB patchset for 4.12-rc1.

        Guenter and others who have taken the time to get this merged. It
        wasn't an easy path for them at all.
      
        There's also a staging driver that uses this new api, which is why
        it's coming in through this tree.
      
        Along with that, there's the usual huge number of changes for gadget
        drivers, xhci, and other stuff. Johan also finally refactored pretty
        much every driver that was looking at USB endpoints to do it in a
        common way, which will help prevent any "badly-formed" devices from
        causing problems in drivers. That too wasn't a simple task.

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.12 kernel cycle.
      
        Core changes:
      
         - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
           This was a much discussed change. It affects use cases where people
           write drivers that might or might not be using GPIO resources. I
           have decided that this is the lesser evil right now.
      
         - Make gpiod_count() behave consistently across different hardware
           descriptions.
      
         - Fix the syntax around open drain/open source to not infer active
           high/low semantics.
      
        New drivers:
      
         - A new single-register fixed-direction framework driver for hardware
           that have lines controlled by a single register that just work in
           one direction (out or in), including IRQ support.
      
         - Support the Fintek F71889A GPIO SuperIO controller.
      
         - Support the National NI 169445 MMIO GPIO.
      
         - Support for the X-Gene derivative of the DWC GPIO controller
      
         - Support for the Rohm BD9571MWV-M PMIC GPIO controller.
      
         - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
           and replace both the Gemini and the Moxa ART custom drivers with
           this driver.
      
        Driver improvements:
      
         - A whole slew of drivers have their spinlocks chaned to raw
           spinlocks as they provide irqchips, and thus we are progressing on
           realtime compliance.
      
         - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
           resources.
      
         - Support for the embedded PWM controller inside the MVEBU driver.
      
         - Debounce, open source and open drain support for the Aspeed driver.
      
         - Misc smaller fixes like spelling and syntax and whatnot"

      Pull x86 platform-drivers update from Darren Hart:
       "This represents a significantly larger and more complex set of changes
        than those of prior merge windows.
      
        In particular, we had several changes with dependencies on other
        subsystems which we felt were best managed through merges of immutable
        branches, including one each from input, i2c, and leds. Two patches
        for the watchdog subsystem are included after discussion with Wim and
        Guenter following a collision in linux-next (this should be resolved
        and you should only see these two appear in this pull request). These
        are called out in the "External" section below.
      
        Summary of changes:
         - significant further cleanup of fujitsu-laptop and hp-wmi
         - new model support for ideapad, asus, silead, and xiaomi
