      Pull more rdma fixes from Doug Ledford:
       "As per my previous pull request, there were two drivers that each had
        a rather large number of legitimate fixes still to be sent.
      
        As it turned out, I also missed a reasonably large set of fixes from
        one person across the stack that are all important fixes. All in all,
        the bnxt_re, i40iw, and Dan Carpenter are 3/4 to 2/3rds of this pull
        request.
      
        There were some other random fixes that I didn't send in the last pull
        request that I added to this one. This catches the rdma stack up to
        the fixes from up to about the beginning of this week. Any more fixes
        I'll wait and batch up later in the -rc cycle. This will give us a
        good base to start with for basing a for-next branch on -rc2.
      
        Summary:
      
         - i40iw fixes
      
         - bnxt_re fixes
      
         - Dan Carpenter bugfixes across stack
      
         - ten more random fixes, no more than two from any one person"

      perf/x86/intel: Add proper condition to run sched_task callbacks · df6c3db8
      Jiri Olsa authored
      We have 2 functions using the same sched_task callback:
      
        - PEBS drain for free running counters
        - LBR save/store
      
      Both of them are called from intel_pmu_sched_task() and
      either of them can be unwillingly triggered when the
      other one is configured to run.
      
      Let's say there's PEBS drain configured in sched_task
      callback for the event, but in the callback itself
      (intel_pmu_sched_task()) we will also run the code for
      LBR save/restore, which we did not ask for, but the
      code in intel_pmu_sched_task() does not check for that.
      
      This can lead to extra cycles in some perf monitoring,
      like when we monitor PEBS event without LBR data.
      
        # perf record --no-timestamp -c 10000 -e cycles:p ./perf bench sched pipe -l 1000000
      
        (We need PEBS, non freq/non timestamp event to enable
         the sched_task callback)
      
      The perf stat of cycles and msr:write_msr for above
      command before the change:
        ...
        Performance counter stats for './perf record --no-timestamp -c 10000 -e cycles:p \
                                       ./perf bench sched pipe -l 1000000' (5 runs):
      
          18,519,557,441      cycles:k
              91,195,527      msr:write_msr
      
            29.334476406 seconds time elapsed
      
      And after the change:
        ...
        Performance counter stats for './perf record --no-timestamp -c 10000 -e cycles:p \
                                       ./perf bench sched pipe -l 1000000' (5 runs):
      
          18,704,973,540      cycles:k
              27,184,720      msr:write_msr
      
            16.977875900 seconds time elapsed
      
      There's no affect on cycles:k because the sched_task happens
      with events switched off, however the msr:write_msr tracepoint
      counter together with almost 50% of time speedup show the
      improvement.
      
      Monitoring LBR event and having extra PEBS drain processing
      in sched_task callback showed just a little speedup, because
      the drain function does not do much extra work in case there
      is no PEBS data.
      
      Adding conditions to recognize the configured work that needs
      to be done in the x86_pmu's sched_task callback.

      The BAU confers no benefit to a UV system running with only one hub/socket.
      Permanently disable the BAU driver if there are less than two hubs online

      systems caused by BAU that are avoided with this patch.
      
      Also, while at it, consolidate initialization error blocks and fix a

      perf/core: Fix locking for children siblings group read · 2aeb1883
      Jiri Olsa authored
      We're missing ctx lock when iterating children siblings
      within the perf_read path for group reading. Following
      race and crash can happen:
      
      User space doing read syscall on event group leader:
      
      T1:
        perf_read
          lock event->ctx->mutex
          perf_read_group
            lock leader->child_mutex
            __perf_read_group_add(child)
              list_for_each_entry(sub, &leader->sibling_list, group_entry)
      
      ---->   sub might be invalid at this point, because it could
              get removed via perf_event_exit_task_context in T2
      
      Child exiting and cleaning up its events:
      
      T2:
        perf_event_exit_task_context
          lock ctx->mutex
          list_for_each_entry_safe(child_event, next, &child_ctx->event_list,...
            perf_event_exit_event(child)
              lock ctx->lock
              perf_group_detach(child)
              unlock ctx->lock
      
      ---->   child is removed from sibling_list without any sync
              with T1 path above
      
              ...
              free_event(child)
      
      Before the child is removed from the leader's child_list,
      (and thus is omitted from perf_read_group processing), we
      need to ensure that perf_read_group touches child's
      siblings under its ctx->lock.

      imx-drm: fix parallel display regression and typo in plane format list
      
      - Fix a regression where the parallel-display driver would not probe
        anymore if no panel is specified in the device tree, since the
        introduction of drm_of_find_panel_or_bridge.
      - Fix a typo in the plane format list: replace a duplicate BGRA8888 format
        with BGRX8888, as originally intended.

      This is a pull request for 4.13-rc2/3. The first patch addresses a bug that
      appears when doing over-subscription of queues, due to a miscalculation of

      net: bonding: Fix transmit load balancing in balance-alb mode · cbf5ecb3
      Kosuke Tatsukawa authored
      balance-alb mode used to have transmit dynamic load balancing feature
      enabled by default.  However, transmit dynamic load balancing no longer
      works in balance-alb after commit 8b426dc5 ("bonding: remove
      hardcoded value").
      
      Both balance-tlb and balance-alb use the function bond_do_alb_xmit() to
      send packets.  This function uses the parameter tlb_dynamic_lb.
      tlb_dynamic_lb used to have the default value of 1 for balance-alb, but
      now the value is set to 0 except in balance-tlb.
      
      Re-enable transmit dyanmic load balancing by initializing tlb_dynamic_lb
      for balance-alb similar to balance-tlb.

      rds: Make sure updates to cp_send_gen can be observed · e623a48e
      Håkon Bugge authored
      cp->cp_send_gen is treated as a normal variable, although it may be
      used by different threads.
      
      This is fixed by using {READ,WRITE}_ONCE when it is incremented and
      READ_ONCE when it is read outside the {acquire,release}_in_xmit
      protection.
      
      Normative reference from the Linux-Kernel Memory Model:
      
          Loads from and stores to shared (but non-atomic) variables should
          be protected with the READ_ONCE(), WRITE_ONCE(), and
          ACCESS_ONCE().
      
      Clause 5.1.2.4/25 in the C standard is also relevant.

      Push the request_irq function to the end of probe so as
      to ensure all the required fields are populated in the event
      of an ISR getting executed right after requesting the irq.
      
      Currently while loading the crash kernel a crash was seen as
      soon as devm_request_threaded_irq was called. This was due to
      n->poll being NULL which is called as part of net_rx_action
      function.

      ipv4: initialize fib_trie prior to register_netdev_notifier call. · 8799a221
      Mahesh Bandewar authored
      Net stack initialization currently initializes fib-trie after the
      first call to netdevice_notifier() call. In fact fib_trie initialization
      needs to happen before first rtnl_register(). It does not cause any problem
      since there are no devices UP at this moment, but trying to bring 'lo'
      UP at initialization would make this assumption wrong and exposes the issue.

      virtnet_set_mac_address() interprets mac address as struct
      sockaddr, but upper layer only allocates dev->addr_len
      which is ETH_ALEN + sizeof(sa_family_t) in this case.
      
      We lack a unified definition for mac address, so just fix
      the upper layer, this also allows drivers to interpret it
      to struct sockaddr freely.

      ... r1 carries an unsigned value, and is compared as unsigned
      against a register carrying an immediate. Verifier deduces in
      reg_set_min_max() that since the compare is unsigned and operation
      is greater than (>), that in the fall-through/false case, r1's
      minimum bound must be 0 and maximum bound must be r2. Latter is
      larger than the bound and thus max value is reset back to being
      'invalid' aka BPF_REGISTER_MAX_RANGE. Thus, r1 state is now
      'R1=inv,min_value=0'. The subsequent test ...
      
        11: (65) if r1 s> 0x1 goto pc+2
      
      ... is a signed compare of r1 with immediate value 1. Here,
      verifier deduces in reg_set_min_max() that since the compare
      is signed this time and operation is greater than (>), that
      in the fall-through/false case, we can deduce that r1's maximum
      bound must be 1, meaning with prior test, we result in r1 having
      the following state: R1=inv,min_value=0,max_value=1. Given that
      the actual value this holds is -8, the bounds are wrongly deduced.
      When this is being added to r0 which holds the map_value(_adj)
      type, then subsequent store access in above case will go through
      check_mem_access() which invokes check_map_access_adj(), that
      will then probe whether the map memory is in bounds based
      on the min_value and max_value as well as access size since
      the actual unknown value is min_value <= x <= max_value; commit
      fce366a9 ("bpf, verifier: fix alu ops against map_value{,
      _adj} register types") provides some more explanation on the
      semantics.
      
      It's worth to note in this context that in the current code,
      min_value and max_value tracking are used for two things, i)
      dynamic map value access via check_map_access_adj() and since
      commit 06c1c049 ("bpf: allow helpers access to variable memory")
      ii) also enforced at check_helper_mem_access() when passing a
      memory address (pointer to packet, map value, stack) and length
      pair to a helper and the length in this case is an unknown value
      defining an access range through min_value/max_value in that
      case. The min_value/max_value tracking is /not/ used in the
      direct packet access case to track ranges. However, the issue
      also affects case ii), for example, the following crafted program
      based on the same principle must be rejected as well:
      
         0: (b7) r2 = 0
         1: (bf) r3 = r10
         2: (07) r3 += -512
         3: (7a) *(u64 *)(r10 -16) = -8
         4: (79) r4 = *(u64 *)(r10 -16)
         5: (b7) r6 = -1
         6: (2d) if r4 > r6 goto pc+5
        R1=ctx R2=imm0,min_value=0,max_value=0,min_align=2147483648 R3=fp-512
        R4=inv,min_value=0 R6=imm-1,max_value=18446744073709551615,min_align=1 R10=fp
         7: (65) if r4 s> 0x1 goto pc+4
        R1=ctx R2=imm0,min_value=0,max_value=0,min_align=2147483648 R3=fp-512
        R4=inv,min_value=0,max_value=1 R6=imm-1,max_value=18446744073709551615,min_align=1
        R10=fp
         8: (07) r4 += 1
         9: (b7) r5 = 0
        10: (6a) *(u16 *)(r10 -512) = 0
        11: (85) call bpf_skb_load_bytes#26
        12: (b7) r0 = 0
        13: (95) exit
      
      Meaning, while we initialize the max_value stack slot that the
      verifier thinks we access in the [1,2] range, in reality we
      pass -7 as length which is interpreted as u32 in the helper.
      Thus, this issue is relevant also for the case of helper ranges.
      Resetting both bounds in check_reg_overflow() in case only one
      of them exceeds limits is also not enough as similar test can be
      created that uses values which are within range, thus also here
      learned min value in r1 is incorrect when mixed with later signed
      test to create a range:
      
         0: (7a) *(u64 *)(r10 -8) = 0
         1: (bf) r2 = r10
         2: (07) r2 += -8
         3: (18) r1 = 0xffff880ad081fa00
         5: (85) call bpf_map_lookup_elem#1
         6: (15) if r0 == 0x0 goto pc+7
        R0=map_value(ks=8,vs=8,id=0),min_value=0,max_value=0 R10=fp
         7: (7a) *(u64 *)(r10 -16) = -8
         8: (79) r1 = *(u64 *)(r10 -16)
         9: (b7) r2 = 2
        10: (3d) if r2 >= r1 goto pc+3
        R0=map_value(ks=8,vs=8,id=0),min_value=0,max_value=0 R1=inv,min_value=3
        R2=imm2,min_value=2,max_value=2,min_align=2 R10=fp
        11: (65) if r1 s> 0x4 goto pc+2
        R0=map_value(ks=8,vs=8,id=0),min_value=0,max_value=0
        R1=inv,min_value=3,max_value=4 R2=imm2,min_value=2,max_value=2,min_align=2 R10=fp
        12: (0f) r0 += r1
        13: (72) *(u8 *)(r0 +0) = 0
        R0=map_value_adj(ks=8,vs=8,id=0),min_value=3,max_value=4
        R1=inv,min_value=3,max_value=4 R2=imm2,min_value=2,max_value=2,min_align=2 R10=fp
        14: (b7) r0 = 0
        15: (95) exit
      
      This leaves us with two options for fixing this: i) to invalidate
      all prior learned information once we switch signed context, ii)
      to track min/max signed and unsigned boundaries separately as
      done in [0]. (Given latter introduces major changes throughout
      the whole verifier, it's rather net-next material, thus this
      patch follows option i), meaning we can derive bounds either
      from only signed tests or only unsigned tests.) There is still the
      case of adjust_reg_min_max_vals(), where we adjust bounds on ALU
      operations, meaning programs like the following where boundaries
      on the reg get mixed in context later on when bounds are merged
      on the dst reg must get rejected, too:
      
         0: (7a) *(u64 *)(r10 -8) = 0
         1: (bf) r2 = r10
         2: (07) r2 += -8
         3: (18) r1 = 0xffff89b2bf87ce00
         5: (85) call bpf_map_lookup_elem#1
         6: (15) if r0 == 0x0 goto pc+6
        R0=map_value(ks=8,vs=8,id=0),min_value=0,max_value=0 R10=fp
         7: (7a) *(u64 *)(r10 -16) = -8
         8: (79) r1 = *(u64 *)(r10 -16)
         9: (b7) r2 = 2
        10: (3d) if r2 >= r1 goto pc+2
        R0=map_value(ks=8,vs=8,id=0),min_value=0,max_value=0 R1=inv,min_value=3
        R2=imm2,min_value=2,max_value=2,min_align=2 R10=fp
        11: (b7) r7 = 1
        12: (65) if r7 s> 0x0 goto pc+2
        R0=map_value(ks=8,vs=8,id=0),min_value=0,max_value=0 R1=inv,min_value=3
        R2=imm2,min_value=2,max_value=2,min_align=2 R7=imm1,max_value=0 R10=fp
        13: (b7) r0 = 0
        14: (95) exit
      
        from 12 to 15: R0=map_value(ks=8,vs=8,id=0),min_value=0,max_value=0
        R1=inv,min_value=3 R2=imm2,min_value=2,max_value=2,min_align=2 R7=imm1,min_value=1 R10=fp
        15: (0f) r7 += r1
        16: (65) if r7 s> 0x4 goto pc+2
        R0=map_value(ks=8,vs=8,id=0),min_value=0,max_value=0 R1=inv,min_value=3
        R2=imm2,min_value=2,max_value=2,min_align=2 R7=inv,min_value=4,max_value=4 R10=fp
        17: (0f) r0 += r7
        18: (72) *(u8 *)(r0 +0) = 0
        R0=map_value_adj(ks=8,vs=8,id=0),min_value=4,max_value=4 R1=inv,min_value=3
        R2=imm2,min_value=2,max_value=2,min_align=2 R7=inv,min_value=4,max_value=4 R10=fp
        19: (b7) r0 = 0
        20: (95) exit
      
      Meaning, in adjust_reg_min_max_vals() we must also reset range
      values on the dst when src/dst registers have mixed signed/
      unsigned derived min/max value bounds with one unbounded value
      as otherwise they can be added together deducing false boundaries.
      Once both boundaries are established from either ALU ops or
      compare operations w/o mixing signed/unsigned insns, then they
      can safely be added to other regs also having both boundaries
      established. Adding regs with one unbounded side to a map value
      where the bounded side has been learned w/o mixing ops is
      possible, but the resulting map value won't recover from that,
      meaning such op is considered invalid on the time of actual
      access. Invalid bounds are set on the dst reg in case i) src reg,
      or ii) in case dst reg already had them. The only way to recover
      would be to perform i) ALU ops but only 'add' is allowed on map
      value types or ii) comparisons, but these are disallowed on
      pointers in case they span a range. This is fine as only BPF_JEQ
      and BPF_JNE may be performed on PTR_TO_MAP_VALUE_OR_NULL registers
      which potentially turn them into PTR_TO_MAP_VALUE type depending
      on the branch, so only here min/max value cannot be invalidated
      for them.
      
      In terms of state pruning, value_from_signed is considered
      as well in states_equal() when dealing with adjusted map values.
      With regards to breaking existing programs, there is a small
      risk, but use-cases are rather quite narrow where this could
      occur and mixing compares probably unlikely.
      
      Joint work with Josef and Edward.

      x86: mark kprobe templates as character arrays, not single characters · 54a7d50b
      Linus Torvalds authored
      They really are, and the "take the address of a single character" makes
      the string fortification code unhappy (it believes that you can now only
      acccess one byte, rather than a byte range, and then raises errors for
      the memory copies going on in there).
      
      We could now remove a few 'addressof' operators (since arrays naturally
      degrade to pointers), but this is the minimal patch that just changes
      the C prototypes of those template arrays (the templates themselves are
      defined in inline asm).
