      i2c: uniphier-f: fix race condition when IRQ is cleared · eaba6878
      Masahiro Yamada authored
      The current IRQ handler clears all the IRQ status bits when it bails
      out. This is dangerous because it might clear away the status bits
      that have just been set while processing the current handler. If this
      happens, the IRQ event for the latest transfer is lost forever.
      
      The IRQ status bits must be cleared *before* the next transfer is
      kicked.

      i2c: uniphier-f: fix occasional timeout error · 39226aaa
      Masahiro Yamada authored
      Currently, a timeout error could happen at a repeated START condition.
      
      For a (non-repeated) START condition, the controller starts sending
      data when the UNIPHIER_FI2C_CR_STA bit is set. However, for a repeated
      START condition, the hardware starts running when the slave address is
      written to the TX FIFO - the write to the UNIPHIER_FI2C_CR register is
      actually unneeded.
      
      Because the hardware is already running before the IRQ is enabled for
      a repeated START, the driver may miss the IRQ event. In most cases,
      this problem does not show up since modern CPUs are much faster than
      the I2C transfer. However, it is still possible that a context switch
      happens after the controller starts, but before the IRQ register is
      set up.
      
      To fix this,
      
       - Do not write UNIPHIER_FI2C_CR for repeated START conditions.
      
       - Enable IRQ *before* writing the slave address to the TX FIFO.
      
       - Disable IRQ for the current CPU while queuing up the TX FIFO;
         If the CPU is interrupted by some task, the interrupt handler
         might be invoked due to the empty TX FIFO before completing the
         setup.

      i2c: uniphier-f: make driver robust against concurrency · f1fdcbbd
      Masahiro Yamada authored
      This is unlikely to happen, but it is possible for a CPU to enter
      the interrupt handler just after wait_for_completion_timeout() has
      expired. If this happens, the hardware is accessed from multiple
      contexts concurrently.
      
      Disable the IRQ after wait_for_completion_timeout(), and do nothing
      from the handler when the IRQ is disabled.

      HID: input: simplify/fix high-res scroll event handling · 044ee890
      Linus Torvalds authored
      Commit 1ff2e1a4 ("HID: input: Create a utility class for counting
      scroll events") created the helper function
      
          hid_scroll_counter_handle_scroll()
      
      to handle high-res scroll events and also expose them as regular wheel
      events.
      
      But the resulting algorithm was unstable, and causes scrolling to be
      very unreliable.  When you hit the half-way mark of the highres
      multiplier, small highres movements will incorrectly translate into big
      traditional wheel movements, causing odd jitters.
      
      Simplify the code and make the output stable.
      
      NOTE! I'm pretty sure this will need further tweaking.  But this at
      least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into
      a usable one.

      Pull 9p updates from Dominique Martinet:
       "Highlights this time around are the end of Matthew's work to remove
        the custom 9p request cache and use a slab directly for requests, with
        some extra patches on my end to not degrade performance, but it's a
        very good cleanup.
      
        Tomas and I fixed a few more syzkaller bugs (refcount is the big one),
        and I had a go at the coverity bugs and at some of the bugzilla
        reports we had open for a while.
      
        I'm a bit disappointed that I couldn't get much reviews for a few of
        my own patches, but the big ones got some and it's all been soaking in
        linux-next for quite a while so I think it should be OK.
      
        Summary:
      
         - Finish removing the custom 9p request cache mechanism
      
         - Embed part of the fcall in the request to have better slab
           performance (msize usually is power of two aligned)
      
         - syzkaller fixes:
            * add a refcount to 9p requests to avoid use after free
            * a few double free issues
      
         - A few coverity fixes

            * do not trust pdu content for size header
            * mount option for lock retry interval"

        We'll continouslly improve csky subsystem in future"
      
      Arnd acks, and adds the following notes:
       "I did a thorough review of the ABI, which as usual mainly consists of
        spotting any files that don't use the asm-generic ABI itself, and
        having it changed to it matches exactly what we do on other new
        architectures.
      
        I also looked at every other patch and commented on maybe half of them
        where I saw something that did not quite seem right. Others have
        reviewed specific patches in greater depth. I'm sure that one could
        fine more of the minor details, but as long as they are not ABI
        relevant, they can be fixed later.
      
        The only patch that is part of the ABI and that nobody reviewed is the
        signal handling. This is one of the areas I never worked on in much
        detail. I did not see anything wrong with it, but I also don't know
        what the problems with the other architectures are here, and we seem
        to be hitting issues occasionally, and we never managed to generalize
        this enough for new architectures to have a trivial implementation.
      
        I was originally hoping that we could have the 64-bit time_t
        interfaces ready in time to completely drop the 32-bit ones, but that
        did not happen. We might still remove them in the next merge window
        depending on whether the libc upstream people prefer to keep them or
        not.
      
        One more general comment: I think this may well be the last new CPU
        architecture we ever add to the kernel. Both nds32 and c-sky are made
        by companies that also work on risc-v, and generally speaking risc-v
        seems to be killing off any of the minor licensable instruction set
        projects, just like ARM has mostly killed off the custom
        vendor-specific instruction sets already.
      
        If we add another architecture in the future, it may instead be
        something like the LLVM bitcode or WebAssembly, who knows?"
      
      To which Geert Uytterhoeven pipes in about another architecture still in
      the pipeline: Kalray MPPA.

      net: diag: document swapped src/dst in udp_dump_one. · 747569b0
      Lorenzo Colitti authored
      Since its inception, udp_dump_one has had a bug where userspace
      needs to swap src and dst addresses and ports in order to find
      the socket it wants. This is because it passes the socket source
      address to __udp[46]_lib_lookup's saddr argument, but those
      functions are intended to find local sockets matching received
      packets, so saddr is the remote address, not the local address.
      
      This can no longer be fixed for backwards compatibility reasons,
      so add a brief comment explaining that this is the case. This
      will avoid confusion and help ensure SOCK_DIAG implementations
      of new protocols don't have the same problem.

      macsec: linkstate fixes
      
      This series fixes issues with handling administrative and operstate of

      Radu Rendec proposed another version of the first patch [0] but I'd
      rather not follow the behavior of vlan devices, going with macvlan
      does instead. Patrick Talbert also reported the same issue to me.
      
      The second patch is a follow-up. The restriction on setting the device
      up is a bit unreasonable, and operstate provides the information we
      need in this case.

      macsec: let the administrator set UP state even if lowerdev is down · 07bddef9
      Sabrina Dubroca authored
      Currently, the kernel doesn't let the administrator set a macsec device
      up unless its lower device is currently up. This is inconsistent, as a
      macsec device that is up won't automatically go down when its lower
      device goes down.
      
      Now that linkstate propagation works, there's really no reason for this
      limitation, so let's remove it.

      macsec: update operstate when lower device changes · e6ac0758
      Sabrina Dubroca authored
      Like all other virtual devices (macvlan, vlan), the operstate of a
      macsec device should match the state of its lower device. This is done
      by calling netif_stacked_transfer_operstate from its netdevice notifier.
      
      We also need to call netif_stacked_transfer_operstate when a new macsec
      device is created, so that its operstate is set properly. This is only
      relevant when we try to bring the device up directly when we create it.
      
      Radu Rendec proposed a similar patch, inspired from the 802.1q driver,
      that included changing the administrative state of the macsec device,
      instead of just the operstate. This version is similar to what the
      macvlan driver does, and updates only the operstate.

      net: sched: gred: pass the right attribute to gred_change_table_def() · 38b4f18d
      Jakub Kicinski authored
      gred_change_table_def() takes a pointer to TCA_GRED_DPS attribute,
      and expects it will be able to interpret its contents as
      struct tc_gred_sopt.  Pass the correct gred attribute, instead of
      TCA_OPTIONS.
      
      This bug meant the table definition could never be changed after
      Qdisc was initialized (unless whatever TCA_OPTIONS contained both
      passed netlink validation and was a valid struct tc_gred_sopt...).
      
      Old behaviour:
      $ ip link add type dummy
      $ tc qdisc replace dev dummy0 parent root handle 7: \

      $ tc qdisc replace dev dummy0 parent root handle 7: \
           gred setup vqs 4 default 0
      RTNETLINK answers: Invalid argument
      
      Now:
      $ ip link add type dummy
      $ tc qdisc replace dev dummy0 parent root handle 7: \

      Building with -Wformat-nonliteral, gcc complains

      kthread_create_worker takes fmt+varargs to set the name of the
      worker, and that happens with a vsnprintf() to a stack buffer (that is
      then copied into task_comm). So there's no reason not to just pass
      "ptp%d", ptp->index to kthread_create_worker() and avoid the
      intermediate worker_name variable.

      net: bridge: remove ipv6 zero address check in mcast queries · 0fe5119e
      Nikolay Aleksandrov authored
      Recently a check was added which prevents marking of routers with zero
      source address, but for IPv6 that cannot happen as the relevant RFCs
      actually forbid such packets:
      RFC 2710 (MLDv1):
      "To be valid, the Query message MUST
       come from a link-local IPv6 Source Address, be at least 24 octets
       long, and have a correct MLD checksum."
      
      Same goes for RFC 3810.
      
      And also it can be seen as a requirement in ipv6_mc_check_mld_query()
      which is used by the bridge to validate the message before processing
      it. Thus any queries with :: source address won't be processed anyway.
      So just remove the check for zero IPv6 source address from the query
      processing function.
      
      Fixes: 5a2de63f ("bridge: do not add port to router list when receives query with source 0.0.0.0")

      Pull VLA removal from Kees Cook:
       "Globally warn on VLA use.
      
        This turns on "-Wvla" globally now that the last few trees with their
        VLA removals have landed (crypto, block, net, and powerpc).
      
        Arnd mentioned that there may be a couple more VLAs hiding in
        hard-to-find randconfigs, but nothing big has shaken out in the last
        month or so in linux-next.
      
        We should be basically VLA-free now! Wheee. :)
      
        Summary:
      
         - Remove unused fallback for BUILD_BUG_ON (which technically contains
           a VLA)

      Pull XArray conversion from Matthew Wilcox:
       "The XArray provides an improved interface to the radix tree data
        structure, providing locking as part of the API, specifying GFP flags
        at allocation time, eliminating preloading, less re-walking the tree,
        more efficient iterations and not exposing RCU-protected pointers to
        its users.
      
        This patch set
      
         1. Introduces the XArray implementation
      
         2. Converts the pagecache to use it
      
         3. Converts memremap to use it
      
        The page cache is the most complex and important user of the radix
        tree, so converting it was most important. Converting the memremap
        code removes the only other user of the multiorder code, which allows
        us to remove the radix tree code that supported it.
      
        I have 40+ followup patches to convert many other users of the radix
        tree over to the XArray, but I'd like to get this part in first. The
        other conversions haven't been in linux-next and aren't suitable for
        applying yet, but you can see them in the xarray-conv branch if you're

      Also, sets DEF_FIELD_ADDR as a specific usage of DEF_FILD_ADDR_VAR in which
      the var name is the same as the struct element name.
      Then, makes use of DEF_FIELD_ADDR_VAR to create a variable of another name,
      in order to avoid variable shadowing.

      HID: we do not randomly make new drivers 'default y' · 69d5b97c
      Linus Torvalds authored
      .. even when that "default y" is hidden syntactically as a
      
      	default !EXPERT
      
      it's wrong.
      
      The only reason something should be 'default y' is if it used to be
      built-in, and it was made configurable, and the 'default y' is just
      retaining the status quo.
      
      Altheratively, the hardware for the driver has become _so_ common that
      it really makes sense for everybody to build it.  Finally, one possible
      reason for 'default y' is because the option is not enabling any new
      code at all, but is just enabling other options (the networking people
      do this for vendor options, for example, so that you can disable whole
      vendors at a time).
      
      Clearly, none of these cases hold for the BigBen Interactive Kids'
      gamepad, and HID_BIGBEN_FF should thus most definitely not default
      to on for everybody.

      i2c-hid: properly terminate i2c_hid_dmi_desc_override_table[] array · b59dfdae
      Linus Torvalds authored
      Commit 9ee3e066 ("HID: i2c-hid: override HID descriptors for certain
      devices") added a new dmi_system_id quirk table to override certain HID
      report descriptors for some systems that lack them.
      
      But the table wasn't properly terminated, causing the dmi matching to
      walk off into la-la-land, and starting to treat random data as dmi
      descriptor pointers, causing boot-time oopses if you were at all
      unlucky.
      
      Terminate the array.
      
      We really should have some way to just statically check that arrays that
      should be terminated by an empty entry actually are so.  But the HID
      people really should have caught this themselves, rather than have me
      deal with an oops during the merge window.  Tssk, tssk.
