  • Prior to the introduction of fib6_info lwtstate was managed by the dst
    code. With fib6_info releasing lwtstate needs to be done when the struct
    is freed.

    ====================
    qed: Misc fixes in the interface with the MFW

    This patch series fixes several issues in the driver's interface with the
    management FW (MFW).

    v1->v2:
    - Fix loop counter decrement to be pre instead of post.

  • Keep sending mailbox commands to the MFW when it is not responsive ends up
    with a redundant amount of timeout expiries.
    This patch prints the MCP status on the first command which is not
    responded, and blocks the following commands.
    Since the (un)load request commands might be not responded due to other
    PFs, the patch also adds the option to skip the blocking upon a failure.

  • The MFW manages an internal lock to prevent concurrent hardware
    (de)initialization of different PFs.
    This, together with the busy-waiting for the MFW's responses for commands,
    might lead to a deadlock during concurrent load or unload of PFs.
    This patch adds the option to sleep within the busy-waiting, and uses it
    for the (un)load requests (which are not sent from an interrupt context) to
    prevent the possible deadlock.

  • Successive iterations of halting and resuming the management chip (MCP)
    might fail, since currently the driver doesn't wait for these operations to
    actually take place.
    This patch prevents the driver from moving forward before the operations
    are reflected in the state register.

  • The MFW might be reset and re-update its shared memory.
    Upon the detection of such a reset the driver rereads this memory, but it
    has to wait till the data is valid.
    This patch adds the missing wait for a data ready indication.

    This because ip6n->tnls_wc[0] point to fallback device in default, but
    in non-default namespace, ip6n->tnls_wc[0] will be NULL, so add the NULL

  • Recently, ops->init() and ops->dump() of all actions were modified to
    always obtain tcf_lock when accessing private action state. Actions that
    don't depend on tcf_lock for synchronization with their data path use
    non-bh locking API. However, tcf_lock is also used to protect rate
    estimator stats in softirq context by timer callback.

    Pull RISC-V updates from Palmer Dabbelt:
    "This contains some major improvements to the RISC-V port, including
    the necessary interrupt controller and timer support to actually make
    it to userspace. Support for three devices has been added:

    - the ISA-mandated timers on RISC-V systems.

    - the ISA-mandated first-level interrupt controller on RISC-V
    systems, which is handled as part of our core arch code because
    it's very small and tightly tied to the ISA.

    - SiFive's platform-level interrupt controller, which talks to the
    actual devices.

    In addition to these new devices, there are a handful of cleanups all
    over the RISC-V tree:

    - build fixes for various configurations:
    * A fix to the vDSO build's makefile so it respects CFLAGS.
    * The addition of __lshrti3, a libgcc derived function necessary
    for some 32-bit configurations.
    * !SMP && PERF_EVENTS

    - Cleanups to the arch code to remove the remnants of old versions of
    the drivers that were just properly submitted.
    * Some dead code from the timer driver, most of which wasn't ever
    even compiled.
    * Cleanups of some interrupt #defines, which are now local to the
    interrupt handling code.

    - Fixes to ptrace(), which while not being sufficient to fully make
    GDB work are at least sufficient to get simple GDB tasks to work.

    - Early printk support via RISC-V's architecturally mandated SBI
    console device.

    - A fix to our early debug trap handler to ensure it's always
    aligned.

    These patches have all been through a fairly extensive review process,
    but as this enables a whole pile of functionality (ie, userspace) I'm
    confident we'll need to submit a few more patches. The only concrete
    issues I know about are the sys_riscv_flush_icache patches, but as I
    managed to screw those up on Friday I figured it'd be best to let them
    bake another week.

    This tag boots a Fedora root filesystem on QEMU's master branch for
    me, and before this morning's rebase (from 4.18-rc8 to 4.18) it booted
    on the HiFive Unleashed.

    Thanks to Christoph Hellwig and the other guys at WD for getting the
    new drivers in shape!"

  • We haven't had lots of deprecation warnings lately, but the rdma use of
    it made them flare up again.

    They are not useful. They annoy everybody, and nobody ever does
    anything about them, because it's always "somebody elses problem". And
    when people start thinking that warnings are normal, they stop looking
    at them, and the real warnings that mean something go unnoticed.

    If you want to get rid of a function, just get rid of it. Convert every
    user to the new world order.

    And if you can't do that, then don't annoy everybody else with your
    marking that says "I couldn't be bothered to fix this, so I'll just spam
    everybody elses build logs with warnings about my laziness".

    Make a kernelnewbies wiki page about things that could be cleaned up,
    write a blog post about it, or talk to people on the mailing lists. But
    don't add warnings to the kernel build about cleanup that you think
    should happen but you aren't doing yourself.

    Don't. Just don't.

    2) Fix a suspicious RCU rcu_dereference_check() warning triggered
    from removing a device's XDP memory allocator by using the correct
    rhashtable lookup function, from Tariq.

    3) A batch of BPF sockmap and ULP fixes mainly fixing leaks and races
    as well as enforcing module aliases for ULPs. Another fix for BPF
    map redirect to make them work again with tail calls, from Daniel.

    Tan Hu.

    2) Do not show negative timeouts in ip_vs_conn by using the new

    5) Use netlink_dump_start() from ctnetlink to fix memleak from

    6) Register nfnetlink_subsys in last place, otherwise netns
    init path may lose race and see net->nft uninitialized data.

    netns refcount, patches from Florian.

    removal, from Florian.

    8) Use GFP_KERNEL_ACCOUNT for xtables blob allocation, from
    Michal Hocko.

    9) Get tproxy documentation in sync with existing codebase,
    from Mate Eckl.

    timeout infrastructure, from Harsha Sharma.

    11) Let uapi nfnetlink_osf.h compile standalone with no errors,
    from Dmitry V. Levin.

    12) Missing braces compilation warning in nft_tproxy, patch from
