      net: sched: always disable bh when taking tcf_lock · 653cd284
      Vlad Buslov 提交于
      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.
      
      Change ops->init() and ops->dump() of all actions to disable bh when using
      tcf_lock to prevent deadlock reported by following lockdep warning:

      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

      pcmcia: remove long deprecated pcmcia_request_exclusive_irq() function · 30779715
      Linus Torvalds 提交于
      This function was created as a deprecated fallback case back in 2010 by
      commit eb14120f ("pcmcia: re-work pcmcia_request_irq()") for legacy
      cases.
      
      Actual in-kernel users haven't been around for a long while.  The last
      in-kernel user was apparently removed four years ago by commit
      5f5316fc ("am2150: Update nmclan_cs.c to use update PCMCIA API").
      
      Just remove it entirely.

      deprecate the '__deprecated' attribute warnings entirely and for good · 771c0353
      Linus Torvalds 提交于
      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.

      Pull USB/PHY updates from Greg KH:
       "Here is the big USB and phy driver patch set for 4.19-rc1.
      
        Nothing huge but there was a lot of work that happened this
        development cycle:
      
         - lots of type-c work, with drivers graduating out of staging, and
           displayport support being added.
      
         - new PHY drivers
      
         - the normal collection of gadget driver updates and fixes
      
         - code churn to work on the urb handling path, using irqsave()
           everywhere in anticipation of making this codepath a lot simpler in
           the future.
      
         - usbserial driver fixes and reworks
      
         - other misc changes
      
        All of these have been in linux-next with no reported issues for a
        while"

      ====================
      pull-request: bpf 2018-08-18
      
      The following pull-request contains BPF updates for your *net* tree.
      
      The main changes are:
      
      1) Fix a BPF selftest failure in test_cgroup_storage due to rlimit
         restrictions, from Yonghong.
      
      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.
      
      4) Fix XDP BPF samples to unload their programs upon SIGTERM, from Jesper.

      ====================
      Netfilter/IPVS fixes for net
      
      The following patchset contains Netfilter/IPVS fixes for your net tree:
      
      1) Infinite loop in IPVS when net namespace is released, from
         Tan Hu.
      
      2) Do not show negative timeouts in ip_vs_conn by using the new
         jiffies_delta_to_msecs(), patches from Matteo Croce.
      
      3) Set F_IFACE flag for linklocal addresses in ip6t_rpfilter,
         from Florian Westphal.
      
      4) Fix overflow in set size allocation, from Taehee Yoo.
      
      5) Use netlink_dump_start() from ctnetlink to fix memleak from
         the error path, again from Florian.
      
      6) Register nfnetlink_subsys in last place, otherwise netns
         init path may lose race and see net->nft uninitialized data.
         This also reverts previous attempt to fix this by increase
         netns refcount, patches from Florian.
      
      7) Remove conntrack entries on layer 4 protocol tracker module
         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.
      
      10) Honor preset layer 3 protocol via ctx->family in the new nft_ct
          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
          Mate Eclk.
      
      13) Disregard bogus check to bail out on non-anonymous sets from
          the dynamic set update extension.
