      tcp: refactor tcp_retransmit_timer() · 0d580fbd
      Eric Dumazet authored
      It appears linux-4.14 stable needs a backport of commit
      88f8598d ("tcp: exit if nothing to retransmit on RTO timeout")
      
      Since tcp_rtx_queue_empty() is not in pre 4.15 kernels,
      let's refactor tcp_retransmit_timer() to only use tcp_rtx_queue_head()
      
      I will provide to stable teams the squashed patches.

      net: mscc: ocelot: unregister the PTP clock on deinit · 9385973f
      Vladimir Oltean authored
      Currently a switch driver deinit frees the regmaps, but the PTP clock is
      still out there, available to user space via /dev/ptpN. Any PTP
      operation is a ticking time bomb, since it will attempt to use the freed
      regmaps and thus trigger kernel panics:

      net: bridge: deny dev_set_mac_address() when unregistering · c4b4c421
      Nikolay Aleksandrov authored
      We have an interesting memory leak in the bridge when it is being
      unregistered and is a slave to a master device which would change the
      mac of its slaves on unregister (e.g. bond, team). This is a very
      unusual setup but we do end up leaking 1 fdb entry because
      dev_set_mac_address() would cause the bridge to insert the new mac address
      into its table after all fdbs are flushed, i.e. after dellink() on the
      bridge has finished and we call NETDEV_UNREGISTER the bond/team would
      release it and will call dev_set_mac_address() to restore its original
      address and that in turn will add an fdb in the bridge.
      One fix is to check for the bridge dev's reg_state in its
      ndo_set_mac_address callback and return an error if the bridge is not in
      NETREG_REGISTERED.
      
      Easy steps to reproduce:
       1. add bond in mode != A/B
       2. add any slave to the bond
       3. add bridge dev as a slave to the bond
       4. destroy the bridge device

      Dash for the m_can (mmio) driver.
      
      The next patch is by Jouni Hogander and fixes a use-after-free in the
      slcan driver.
      
      Johan Hovold's patch for the ucan driver fixes the non-atomic allocation
      in the completion handler.
      
      The last two patches target the xilinx-can driver. The first one is by
      Venkatesh Yadav Abbarapu and skips the error message on deferred probe,
      the second one is by Srinivas Neeli and fixes the usage of the skb after
      can_put_echo_skb().

      Slcan_open doesn't clean-up device which registration failed from the
      slcan_devs device list. On next open this list is iterated and freed
      device is accessed. Fix this by calling slc_free_netdev in error path.
      
      Driver/net/can/slcan.c is derived from slip.c. Use-after-free error was
      identified in slip_open by syzboz. Same bug is in slcan.c. Here is the

      Fixed updating of ethertype in function skb_mpls_pop · 040b5cfb
      Martin Varghese authored
      The skb_mpls_pop was not updating ethertype of an ethernet packet if the
      packet was originally received from a non ARPHRD_ETHER device.
      
      In the below OVS data path flow, since the device corresponding to port 7
      is an l3 device (ARPHRD_NONE) the skb_mpls_pop function does not update
      the ethertype of the packet even though the previous push_eth action had
      added an ethernet header to the packet.
      
      recirc_id(0),in_port(7),eth_type(0x8847),
      mpls(label=12/0xfffff,tc=0/0,ttl=0/0x0,bos=1/1),
      actions:push_eth(src=00:00:00:00:00:00,dst=00:00:00:00:00:00),
      pop_mpls(eth_type=0x800),4

      libbpf: Fix readelf output parsing on powerpc with recent binutils · 3464afdf
      Aurelien Jarno authored
      On powerpc with recent versions of binutils, readelf outputs an extra
      field when dumping the symbols of an object file. For example:
      
          35: 0000000000000838    96 FUNC    LOCAL  DEFAULT [<localentry>: 8]     1 btf_is_struct
      
      The extra "[<localentry>: 8]" prevents the GLOBAL_SYM_COUNT variable to
      be computed correctly and causes the check_abi target to fail.
      
      Fix that by looking for the symbol name in the last field instead of the
      8th one. This way it should also cope with future extra fields.

      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v5.5 kernel cycle
      
        Core changes:
      
         - Expose pull up/down flags for the GPIO character device to
           userspace.
      
           After clear input from the RaspberryPi and Beagle communities, it
           has been established that prototyping, industrial automation and
           make communities strongly need this feature, and as we want people
           to use the character device, we have implemented the simple pull
           up/down interface for GPIO lines.
      
           This means we can specify that a (chip-specific) pull up/down
           resistor can be enabled, but does not offer fine-grained control
           such as cases where the resistance of the same pull resistor can be
           controlled (yet).
      
         - Introduce devm_fwnode_gpiod_get_index() and start to phase out the
           old symbol devm_fwnode_get_index_gpiod_from_child().
      
         - A bit of documentation clean-up work.
      
         - Introduce a define for GPIO line directions and deploy it in all
           GPIO drivers in the drivers/gpio directory.
      
         - Add a special callback to populate pin ranges when cooperating with
           the pin control subsystem and registering ranges as part of adding
           a gpiolib driver and a gpio_irq_chip driver at the same time. This
           is also deployed in the Intel Merrifield driver.
      
        New drivers:
      
         - RDA Micro GPIO controller.
      
         - XGS-iproc GPIO driver.
      
        Driver improvements:
      
         - Wake event and debounce support on the Tegra 186 driver.
      
         - Finalize the Aspeed SGPIO driver.
      
         - MPC8xxx uses a normal IRQ handler rather than a chained handler"

      Pull clk updates from Stephen Boyd:
       "This merge window we have one small clk provider API in the core
        framework and then a bunch of driver updates and a handful of new
        drivers. In terms of diffstat the Qualcomm and Amlogic drivers are
        high up there because of all the clk data introcued by new drivers.
        The Nvidia Tegra driver had a lot of work done this cycle too to
        support suspend/resume and memory controllers. And the OMAP clk driver
        got proper clk and reset handling in place.
      
        Rounding out the patches are various updates to remove unused data,
        mark things static, correct incorrect data in drivers, etc. All the
        little things that improve drivers and maintain code health. I will
        point out that there's a patch in here for the GPIO clk driver, that
        almost nobody uses, which changes behavior and causes clk_set_rate()
        to try to change the GPIO gate clk's parent. Other than that things
        are fairly well SoC specific here.
      
        Core:
         - Add a clk provider API to get current parent index
         - Plug a memory leak in clk_unregister() path
      
        New Drivers:
         - CGU in Ingenix X1000
         - Bitmain BM1880 clks
         - Qualcomm MSM8998 GPU clk controllers
         - Qualcomm SC7180 GCC and RPMH clk controllers
         - Qualcomm QCS404 Q6SSTOP clk controllers
         - Add support for the Renesas R-Car M3-W+ (r8a77961) SoC
         - Add support for the Renesas RZ/G2N (r8a774b1) SoC
         - Add Tegra20/30 External Memory Clock (EMC) support
      
        Updates:
         - Make gpio gate clks propagate rate setting up to parent
         - Prepare Armada 3700 for suspend to RAM by moving PCIe
           suspend/resume priority
         - Drop unused variables, enums, etc. in various clk drivers
         - Convert various drivers to use devm_platform_ioremap_resource()
         - Use struct_size() some more in various clk drivers
         - Improve Rockchip px30 clk tree
         - Add suspend/resume support to Tegra210 clk driver
         - Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP
         - Allwinner DT exports and H6 clk tree fixes
         - Proper clk and reset handling for OMAP SoCs
         - Revamped TI divider clk to clamp max divider
         - Make 1443X/1416X PLL clock structure common for reusing among i.MX8
           SoCs
         - Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used
         - Add VIDEO2_PLL clock for imx8mq
         - Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs
         - Add sm1 support in the Amlogic audio clock controller
         - Switch some clocks on R-Car Gen2/3 to .determine_rate()
         - Remove Renesas R-Car Gen2 legacy DT clock support
         - Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3
         - Improve Renesas R-Car Gen3 SD clock handling
         - Add rate table for Samsung exynos542x GPU and VPLL clks
         - Fix potential CPU performance degradation after system
           suspend/resume cycle on exynos542x SoCs"

        This is a series of cleanups for the y2038 work, mostly intended for
        namespace cleaning: the kernel defines the traditional time_t, timeval
        and timespec types that often lead to y2038-unsafe code. Even though
        the unsafe usage is mostly gone from the kernel, having the types and
        associated functions around means that we can still grow new users,
        and that we may be missing conversions to safe types that actually
        matter.
      
        There are still a number of driver specific patches needed to get the
        last users of these types removed, those have been submitted to the
        respective maintainers"

      Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
       "As part of the cleanup of some remaining y2038 issues, I came to
        fs/compat_ioctl.c, which still has a couple of commands that need
        support for time64_t.
      
        In completely unrelated work, I spent time on cleaning up parts of
        this file in the past, moving things out into drivers instead.
      
        After Al Viro reviewed an earlier version of this series and did a lot
        more of that cleanup, I decided to try to completely eliminate the
        rest of it and move it all into drivers.
      
        This series incorporates some of Al's work and many patches of my own,
        but in the end stops short of actually removing the last part, which
        is the scsi ioctl handlers. I have patches for those as well, but they
        need more testing or possibly a rewrite"

      Pull sysctl system call removal from Eric Biederman:
       "As far as I can tell we have reached the point where no one enables
        the sysctl system call anymore. It still is enabled in a few
        defconfigs but they are mostly the rarely used one and in asking
        people about that it was more cut & paste enabled than anything else.
      
        This is single commit that just deletes code. Leaving just enough code
        so that the deprecated sysctl warning continues to be printed. If my
        analysis turns out to be wrong and someone actually cares it will be
        easy to revert this commit and have the system call again.
      
        There was one new xtensa defconfig in linux-next that enabled the
        system call this cycle and when asked about it the maintainer of the
        code replied that it was not enabled on purpose. As of today's
        linux-next tree that defconfig no longer enables the system call.
      
        What we saw in the review discussion was that if we go a step farther
        than my patch and mess with uapi headers there are pieces of code that
        won't compile, but nothing minds the system call actually disappearing
        from the kernel"
