      platform/chrome: cros_ec_proto: check for missing EC_CMD_HOST_EVENT_GET_WAKE_MASK · fc8cacf3
      Brian Norris authored
      As with cros_ec_cmd_xfer_status(), etc., it's not enough to simply check
      for the return status of send_command() -- that only covers transport or
      other similarly-fatal errors. One must also check the ->result field, to
      see whether the command really succeeded. If not, we can't use the data
      it returns.
      
      The caller of cros_ec_get_host_event_wake_mask() ignores this, and so
      for example, on EC's where the command is not implemented, we're using
      junk (or in practice, all zeros) for our wake-mask. We should be using a
      non-zero default (currently, it's supposed to be all-1's).
      
      Fix this by checking the ->result field and returning -EPROTO for
      errors.
      
      I might label this as fixing commit 29d99b96 ("cros_ec: Don't signal
      wake event for non-wake host events"), except that this fix alone
      actually may make things worse, as it now allows for a lot more spurious
      wakeups. The patch "platform/chrome: cros_ec_proto: ignore battery/AC
      wakeups on old ECs" helps to mitigate this.

      platform/chrome: cros_ec_proto: ignore unnecessary wakeups on old ECs · c214e564
      Brian Norris authored
      ECs that don't implement EC_CMD_HOST_EVENT_GET_WAKE_MASK should still
      have some reasonable default mask -- otherwise, they'll treat a variety
      of EC signals as spurious wakeups. Battery and AC events can be
      especially common, for devices that have been sitting at full charge
      plugged into AC for a long time, as they may cycle their charging off
      and on, or their battery may start reporting failures as it ages.
      
      Treating these as wakeups does not serve a useful purpose, and is
      instead often counterproductive. And indeed, later ECs (that implement
      the mask) don't include these events in their wake-mask.
      
      Note that this patch doesn't do anything without the subsequent patch
      ("platform/chrome: cros_ec_proto: check for missing
      EC_CMD_HOST_EVENT_GET_WAKE_MASK"), because
      cros_ec_get_host_event_wake_mask() currently does not return an error if
      EC_CMD_HOST_EVENT_GET_WAKE_MASK is not implemented.
      
      Some additional notes:
      While the EC typically knows not to wake the CPU for these unimportant
      events once the CPU reaches a sleep state, it doesn't really have a way
      to know that the CPU is "almost" asleep, unless it has support for
      EC_CMD_HOST_SLEEP_EVENT. Alas, these older ECs do not support that
      command either, so this solution is not 100% complete.

      platform/chrome: cros_ec_sensorhub: Simplify legacy timestamp spreading · 7f4784f1
      Gwendal Grignou authored
      On some machines (nami), interrupt latency cause samples to appear
      to be from the future and are pegged to the current time.
      We would see samples with this pattern:
      
      [t, t + ~5ms, t + ~10ms, t + ~10ms + 100us, t + ~10ms + 200us],
                                   (current now)      (current now)
      (t is the last timestamp time)
      
      Last 2 samples would be barely spread, causing applications to
      complain.
      
      We now spread the entire sequence. This is not great: in the example
      the sensor was supposed to send samples every 5ms, it now appears to
      send one every 2.5ms, but it is slightly closer to reality:

      security: Add LSM hooks to set*gid syscalls · 39030e13
      Thomas Cedeno authored
      The SafeSetID LSM uses the security_task_fix_setuid hook to filter
      set*uid() syscalls according to its configured security policy. In
      preparation for adding analagous support in the LSM for set*gid()
      syscalls, we add the requisite hook here. Tested by putting print
      statements in the security_task_fix_setgid hook and seeing them get hit
      during kernel boot.

      Revert "btrfs: switch to iomap_dio_rw() for dio" · 55e20bd1
      David Sterba authored
      This reverts commit a43a67a2.
      
      This patch reverts the main part of switching direct io implementation
      to iomap infrastructure. There's a problem in invalidate page that
      couldn't be solved as regression in this development cycle.
      
      The problem occurs when buffered and direct io are mixed, and the ranges
      overlap. Although this is not recommended, filesystems implement
      measures or fallbacks to make it somehow work. In this case, fallback to
      buffered IO would be an option for btrfs (this already happens when
      direct io is done on compressed data), but the change would be needed in
      the iomap code, bringing new semantics to other filesystems.
      
      Another problem arises when again the buffered and direct ios are mixed,
      invalidation fails, then -EIO is set on the mapping and fsync will fail,
      though there's no real error.
      
      There have been discussions how to fix that, but revert seems to be the
      least intrusive option.

      net: ethernet: ti: ale: fix allmulti for nu type ale · bc139119
      Grygorii Strashko authored
      On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
      unregistered mcast packets to pass.
      
      This happens, because ALE VLAN entries on these SoCs do not contain port
      masks for reg/unreg mcast packets, but instead store indexes of
      ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
      reg/unreg mcast packets.
      This path was missed by commit 9d1f6447 ("net: ethernet: ti: ale: fix
      seeing unreg mcast packets with promisc and allmulti disabled").
      
      Hence, fix it by taking into account ALE type in cpsw_ale_set_allmulti().

      Linus Torvalds authored
      Pull i2c updates from Wolfram Sang:
       "I2C has quite some patches for you this time. I hope it is the move to
        per-driver-maintainers which is now showing results. We will see.
      
        The big news is two new drivers (Nuvoton NPCM and Qualcomm CCI),
        larger refactoring of the Designware, Tegra, and PXA drivers, the
        Cadence driver supports being a slave now, and there is support to
        instanciate SPD eeproms for well-known cases (which will be
        user-visible because the i801 driver supports it), and some
        devm_platform_ioremap_resource() conversions which blow up the
        diffstat.
      
        Note that I applied the Nuvoton driver quite late, so some minor fixup
        patches arrived during the merge window. I chose to apply them right
        away because they were trivial"

      Pull more media updates from Mauro Carvalho Chehab:
      
       - a set of atomisp patches. They remove several abstraction layers, and
         fixes clang and gcc warnings (that were hidden via some macros that
         were disabling 4 or 5 types of warnings there). There are also some
         important fixes and sensor auto-detection on newer BIOSes via ACPI
         _DCM tables.
