      Pull RISC-V fixes from Palmer Dabbelt:
       "I've collected a handful of fixes over the past few weeks:
      
         - A fix to un-break the build-id argument to the vDSO build, which is
           necessary for the LLVM linker.
      
         - A fix to initialize the jump label subsystem, without which it (and
           all the stuff that uses it) doesn't actually function.
      
         - A fix to include <asm/barrier.h> from <vdso/processor.h>, without
           which some drivers won't compile"

        fix for when you have a 2.4Ghz Wifi and a HDMI signal with a clock in
        that range and there isn't enough shielding and interference happen
        between the two, the fix adjusts the mode clock to try and avoid the
        wifi channels in that case.

      ====================
      pull-request: can 2020-11-27
      
      The first patch is by me and target the gs_usb driver and fixes the endianess
      problem with candleLight firmware.
      
      Another patch by me for the mcp251xfd driver add sanity checking to bail out if
      no IRQ is configured.
      
      The next three patches target the m_can driver. A patch by me removes the
      hardcoded IRQF_TRIGGER_FALLING from the request_threaded_irq() as this clashes
      with the trigger level specified in the DT. Further a patch by me fixes the
      nominal bitiming tseg2 min value for modern m_can cores. Pankaj Sharma's patch
      add support for cores version 3.3.x.
      
      The last patch by Oliver Hartkopp is for af_can and converts a WARN() into a
      pr_warn(), which is triggered by the syzkaller. It was able to create a
      situation where the closing of a socket runs simultaneously to the notifier
      call chain for removing the CAN network device in use.

      sock: set sk_err to ee_errno on dequeue from errq · 985f7337
      Willem de Bruijn authored
      When setting sk_err, set it to ee_errno, not ee_origin.
      
      Commit f5f99309 ("sock: do not set sk_err in
      sock_dequeue_err_skb") disabled updating sk_err on errq dequeue,
      which is correct for most error types (origins):
      
        -       sk->sk_err = err;
      
      Commit 38b25793 ("sock: reset sk_err when the error queue is
      empty") reenabled the behavior for IMCP origins, which do require it:
      
        +       if (icmp_next)
        +               sk->sk_err = SKB_EXT_ERR(skb_next)->ee.ee_origin;
      
      But read from ee_errno.

      mptcp: fix NULL ptr dereference on bad MPJ · d3ab7885
      Paolo Abeni authored
      If an msk listener receives an MPJ carrying an invalid token, it
      will zero the request socket msk entry. That should later
      cause fallback and subflow reset - as per RFC - at
      subflow_syn_recv_sock() time due to failing hmac validation.
      
      Since commit 4cf8b7e4 ("subflow: introduce and use
      mptcp_can_accept_new_subflow()"), we unconditionally dereference
      - in mptcp_can_accept_new_subflow - the subflow request msk
      before performing hmac validation. In the above scenario we
      hit a NULL ptr dereference.
      
      Address the issue doing the hmac validation earlier.
      
      Fixes: 4cf8b7e4 ("subflow: introduce and use mptcp_can_accept_new_subflow()")

      net: openvswitch: fix TTL decrement action netlink message format · 69929d4c
      Eelco Chaudron authored
      Currently, the openvswitch module is not accepting the correctly formated
      netlink message for the TTL decrement action. For both setting and getting
      the dec_ttl action, the actions should be nested in the
      OVS_DEC_TTL_ATTR_ACTION attribute as mentioned in the openvswitch.h uapi.
      
      When the original patch was sent, it was tested with a private OVS userspace
      implementation. This implementation was unfortunately not upstreamed and
      reviewed, hence an erroneous version of this patch was sent out.
      
      Leaving the patch as-is would cause problems as the kernel module could
      interpret additional attributes as actions and vice-versa, due to the
      actions not being encapsulated/nested within the actual attribute, but
      being concatinated after it.

      perf probe: Change function definition check due to broken DWARF · a9ffd048
      Masami Hiramatsu authored
      Since some gcc generates a broken DWARF which lacks DW_AT_declaration
      attribute from the subprogram DIE of function prototype.
      (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97060)
      
      So, in addition to the DW_AT_declaration check, we also check the
      subprogram DIE has DW_AT_inline or actual entry pc.

      Fix die_entrypc() to return error correctly if the DIE has no

      empty ranges and return 0, we have to check it by ourselves.

      perf stat: Use proper cpu for shadow stats · c0ee1d5a
      Namhyung Kim authored
      Currently perf stat shows some metrics (like IPC) for defined events.
      But when no aggregation mode is used (-A option), it shows incorrect
      values since it used a value from a different cpu.
      
      Before:
      
        $ perf stat -aA -e cycles,instructions sleep 1
      
         Performance counter stats for 'system wide':
      
        CPU0      116,057,380      cycles
        CPU1       86,084,722      cycles
        CPU2       99,423,125      cycles
        CPU3       98,272,994      cycles
        CPU0       53,369,217      instructions      #    0.46  insn per cycle
        CPU1       33,378,058      instructions      #    0.29  insn per cycle
        CPU2       58,150,086      instructions      #    0.50  insn per cycle
        CPU3       40,029,703      instructions      #    0.34  insn per cycle
      
             1.001816971 seconds time elapsed
      
      So the IPC for CPU1 should be 0.38 (= 33,378,058 / 86,084,722)
      but it was 0.29 (= 33,378,058 / 116,057,380) and so on.
      
      After:
      
        $ perf stat -aA -e cycles,instructions sleep 1
      
         Performance counter stats for 'system wide':
      
        CPU0      109,621,384      cycles
        CPU1      159,026,454      cycles
        CPU2       99,460,366      cycles
        CPU3      124,144,142      cycles
        CPU0       44,396,706      instructions      #    0.41  insn per cycle
        CPU1      120,195,425      instructions      #    0.76  insn per cycle
        CPU2       44,763,978      instructions      #    0.45  insn per cycle
        CPU3       69,049,079      instructions      #    0.56  insn per cycle
      
             1.001910444 seconds time elapsed

      perf record: Synthesize cgroup events only if needed · aa50d953
      Namhyung Kim authored
      It didn't check the tool->cgroup_events bit which is set when the
      --all-cgroups option is given.  Without it, samples will not have cgroup
      info so no reason to synthesize.
      
      We can check the PERF_RECORD_CGROUP records after running perf record
      *WITHOUT* the --all-cgroups option:
      
      Before:

                CGROUP events:          0
      
      After:
      
        $ perf report -D | grep CGROUP
                CGROUP events:          0

                CGROUP events:          0
      
      Committer testing:
      
      Before:

      perf tools: Update copy of libbpf's hashmap.c · 3b13eaf0
      Arnaldo Carvalho de Melo authored
      To pick the changes in:
      
        7a078d2d ("libbpf, hashmap: Fix undefined behavior in hash_bits")
      
      That don't entail any changes in tools/perf.
      
      This addresses this perf build warning:
      
        Warning: Kernel ABI header at 'tools/perf/util/hashmap.h' differs from latest version at 'tools/lib/bpf/hashmap.h'
        diff -u tools/perf/util/hashmap.h tools/lib/bpf/hashmap.h
      
      Not a kernel ABI, its just that this uses the mechanism in place for
      checking kernel ABI files drift.
