      Pull libnvdimm updates from Dan Williams:
       "The libnvdimm pull request is relatively small this time around due to
        some development topics being deferred to 4.11.
      
        As for this pull request the bulk of it has been in -next for several
        releases leading to one late fix being added (commit 868f036f
        ("libnvdimm: fix mishandled nvdimm_clear_poison() return value")). It
        has received a build success notification from the 0day-kbuild robot
        and passes the latest libnvdimm unit tests.
      
        Summary:
      
         - Dynamic label support: To date namespace label support has been
           limited to disambiguating cases where PMEM (direct load/store) and
           BLK (mmio aperture) accessed-capacity alias on the same DIMM. Since
           4.9 added support for multiple namespaces per PMEM-region there is
           value to support namespace labels even in the non-aliasing case.
           The presence of a valid namespace index block force-enables label
           support when the kernel would otherwise rely on region boundaries,
           and permits the region to be sub-divided.
      
         - Handle media errors in namespace metadata: Complement the error
           handling for media errors in namespace data areas with support for
           clearing errors on writes, and downgrading potential machine-check
           exceptions to simple i/o errors on read.
      
         - Device-DAX region attributes: Add 'align', 'id', and 'size' as
           attributes for device-dax regions. In particular this enables
           userspace tooling to generically size memory mapping and i/o
           operations. Prevent userspace from growing assumptions /
           dependencies about the parent device topology for a dax region. A
           libnvdimm namespace may not always be the parent device of a dax
           region.
      
         - Various cleanups and small fixes"

      Pull timer updates from Thomas Gleixner:
       "This is the last functional update from the tip tree for 4.10. It got
        delayed due to a newly reported and anlyzed variant of BIOS bug and
        the resulting wreckage:
      
         - Seperation of TSC being marked realiable and the fact that the
           platform provides the TSC frequency via CPUID/MSRs and making use
           for it for GOLDMONT.
      
         - TSC adjust MSR validation and sanitizing:
      
           The TSC adjust MSR contains the offset to the hardware counter. The
           sum of the adjust MSR and the counter is the TSC value which is
           read via RDTSC.
      
           On at least two machines from different vendors the BIOS sets the
           TSC adjust MSR to negative values. This happens on cold and warm
           boot. While on cold boot the offset is a few milliseconds, on warm
           boot it basically compensates the power on time of the system. The
           BIOSes are not even using the adjust MSR to set all CPUs in the
           package to the same offset. The offsets are different which renders
           the TSC unusable,
      
           What's worse is that the TSC deadline timer has a HW feature^Wbug.
           It malfunctions when the TSC adjust value is negative or greater
           equal 0x80000000 resulting in silent boot failures, hard lockups or
           non firing timers. This looks like some hardware internal 32/64bit
           issue with a sign extension problem. Intel has been silent so far
           on the issue.
      
           The update contains sanity checks and keeps the adjust register
           within working limits and in sync on the package.
      
           As it looks like this disease is spreading via BIOS crapware, we
           need to address this urgently as the boot failures are hard to
           debug for users"

      x86/tsc: Limit the adjust value further · 8c9b9d87
      Thomas Gleixner authored
      Adjust value 0x80000000 and other values larger than that render the TSC
      deadline timer disfunctional.
      
      We have not yet any information about this from Intel, but experimentation
      clearly proves that this is a 32/64 bit and sign extension issue.
      
      If adjust values larger than that are actually required, which might be the
      case for physical CPU hotplug, then we need to disable the deadline timer
      on the affected package/CPUs and use the local APIC timer instead.
      
      That requires some surgery in the APIC setup code, so we just limit the
      ADJUST register value into the known to work range for now and revisit this
      when Intel comes forth with proper information.

      cgroup: Fix CGROUP_BPF config · 483c4933
      Andy Lutomirski authored
      CGROUP_BPF depended on SOCK_CGROUP_DATA which can't be manually
      enabled, making it rather challenging to turn CGROUP_BPF on.

      ====================
      Three fixes:
       * avoid a WARN_ON() when trying to use WEP with AP_VLANs
       * ensure enough headroom on mesh forwarding packets
       * don't report unknown/invalid rates to userspace

      net: ipv6: check route protocol when deleting routes · c2ed1880
      Mantas M authored
      The protocol field is checked when deleting IPv4 routes, but ignored for
      IPv6, which causes problems with routing daemons accidentally deleting
      externally set routes (observed by multiple bird6 users).
      
      This can be verified using `ip -6 route del <prefix> proto something`.

      r6040: move spinlock in r6040_close as SOFTIRQ-unsafe lock order detected · c762eaa7
      Manuel Bessler authored
      'ifconfig eth0 down' makes r6040_close() trigger:

      Fixed by moving calls to phy_stop(), napi_disable(), netif_stop_queue()
      to outside of the module's private spin_lock_irq block.

      Daniel Borkmann says:
      
      ====================
      Couple of BPF fixes
      
      This set contains three BPF fixes for net, one that addresses the
      complaint from Geert wrt static allocations, and the other is a fix
      wrt mem accounting that I found recently during testing and there's
      still one more fix on the map value marking.
      
      Thanks!
      
      v1 -> v2:
        - Patch 1 as is.
        - Fixed kbuild bot issue by letting charging helpers stay in the
          syscall.c, since there locked_vm is valid and only export the
          ones needed by bpf_prog_realloc(). Add empty stubs in case the
          bpf syscall is not enabled.
        - Added patch 3 that addresses one more issue in map val marking.

      This issue got uncovered after the fix in a08dd0da ("bpf: fix
      regression on verifier pruning wrt map lookups"). The reason why it
      wasn't noticed before was, because as mentioned in a08dd0da,
      mark_map_regs() was doing the id matching incorrectly based on the
      uncached regs[regno].id. So, in the first loop, we walked all regs
      and as soon as we found regno == i, then this reg's id was cleared
      when calling mark_reg_unknown_value() thus that every subsequent
      register was probed against id of 0 (which, in combination with the
      PTR_TO_MAP_VALUE_OR_NULL type is an invalid condition that no other
      register state can hold), and therefore wasn't type transitioned such
      as in the spilled register case for the second loop.
      
      Now since that got fixed, it turned out that 57a09bf0 ("bpf:
      Detect identical PTR_TO_MAP_VALUE_OR_NULL registers") used
      mark_reg_unknown_value() incorrectly for the spilled regs, and thus
      hitting the BUG_ON() in some cases due to regno >= MAX_BPF_REG.
      
      Although spilled regs have the same type as the non-spilled regs
      for the verifier state, that is, struct bpf_reg_state, they are
      semantically different from the non-spilled regs. In other words,
      there can be up to 64 (MAX_BPF_STACK / BPF_REG_SIZE) spilled regs
      in the stack, for example, register R<x> could have been spilled by
      the program to stack location X, Y, Z, and in mark_map_regs() we
      need to scan these stack slots of type STACK_SPILL for potential
      registers that we have to transition from PTR_TO_MAP_VALUE_OR_NULL.
      Therefore, depending on the location, the spilled_regs regno can
      be a lot higher than just MAX_BPF_REG's value since we operate on
      stack instead. The reset in mark_reg_unknown_value() itself is
      just fine, only that the BUG_ON() was inappropriate for this. Fix
      it by making a __mark_reg_unknown_value() version that can be
      called from mark_map_reg() generically; we know for the non-spilled
      case that the regno is always < MAX_BPF_REG anyway.

      bpf: fix overflow in prog accounting · 5ccb071e
      Daniel Borkmann authored
      Commit aaac3ba9 ("bpf: charge user for creation of BPF maps and
      programs") made a wrong assumption of charging against prog->pages.
      Unlike map->pages, prog->pages are still subject to change when we
      need to expand the program through bpf_prog_realloc().
      
      This can for example happen during verification stage when we need to
      expand and rewrite parts of the program. Should the required space
      cross a page boundary, then prog->pages is not the same anymore as
      its original value that we used to bpf_prog_charge_memlock() on. Thus,
      we'll hit a wrap-around during bpf_prog_uncharge_memlock() when prog
      is freed eventually. I noticed this that despite having unlimited
      memlock, programs suddenly refused to load with EPERM error due to
      insufficient memlock.
      
      There are two ways to fix this issue. One would be to add a cached
      variable to struct bpf_prog that takes a snapshot of prog->pages at the
      time of charging. The other approach is to also account for resizes. I
      chose to go with the latter for a couple of reasons: i) We want accounting
      rather to be more accurate instead of further fooling limits, ii) adding
      yet another page counter on struct bpf_prog would also be a waste just
      for this purpose. We also do want to charge as early as possible to
      avoid going into the verifier just to find out later on that we crossed
      limits. The only place that needs to be fixed is bpf_prog_realloc(),
      since only here we expand the program, so we try to account for the
      needed delta and should we fail, call-sites check for outcome anyway.
      On cBPF to eBPF migrations, we don't grab a reference to the user as
      they are charged differently. With that in place, my test case worked
      fine.

      bpf: dynamically allocate digest scratch buffer · aafe6ae9
      Daniel Borkmann authored
      Geert rightfully complained that 7bd509e3 ("bpf: add prog_digest
      and expose it via fdinfo/netlink") added a too large allocation of
      variable 'raw' from bss section, and should instead be done dynamically:
      
        # ./scripts/bloat-o-meter kernel/bpf/core.o.1 kernel/bpf/core.o.2
        add/remove: 3/0 grow/shrink: 0/0 up/down: 33291/0 (33291)
        function                                     old     new   delta
        raw                                            -   32832  +32832
        [...]
      
      Since this is only relevant during program creation path, which can be
      considered slow-path anyway, lets allocate that dynamically and be not
      implicitly dependent on verifier mutex. Move bpf_prog_calc_digest() at
      the beginning of replace_map_fd_with_map_ptr() and also error handling
      stays straight forward.
