       - During this merge window O_NONBLOCK was changed to become 000200000,
         but we missed that the syscalls timerfd_create(), signalfd4(),
         eventfd2(), pipe2(), inotify_init1() and userfaultfd() do a strict
         bit-wise check of the flags parameter.
      
         To provide backward compatibility with existing userspace we
         introduce parisc specific wrappers for those syscalls which filter
         out the old O_NONBLOCK value and replaces it with the new one.
      
       - Prevent HIL bus driver to get stuck when keyboard or mouse isn't

       "Make prandom_u32() less predictable.
      
        This is the cleanup of the latest series of prandom_u32
        experimentations consisting in using SipHash instead of Tausworthe to
        produce the randoms used by the network stack.
      
        The changes to the files were kept minimal, and the controversial
        commit that used to take noise from the fast_pool (f227e3ec) was
        reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is
        fed from various sources of activities (networking, scheduling) to
        perturb the SipHash state using fast, non-trivially predictable data,
        instead of keeping it fully deterministic. The goal is essentially to
        make any occasional memory leakage or brute-force attempt useless.
      
        The resulting code was verified to be very slightly faster on x86_64
        than what is was with the controversial commit above, though this
        remains barely above measurement noise. It was also tested on i386 and
        arm, and build- tested only on arm64"

      random32: add noise from network and scheduling activity · 3744741a
      Willy Tarreau authored
      With the removal of the interrupt perturbations in previous random32
      change (random32: make prandom_u32() output unpredictable), the PRNG
      has become 100% deterministic again. While SipHash is expected to be
      way more robust against brute force than the previous Tausworthe LFSR,
      there's still the risk that whoever has even one temporary access to
      the PRNG's internal state is able to predict all subsequent draws till
      the next reseed (roughly every minute). This may happen through a side
      channel attack or any data leak.
      
      This patch restores the spirit of commit f227e3ec ("random32: update
      the net random state on interrupt and activity") in that it will perturb
      the internal PRNG's statee using externally collected noise, except that
      it will not pick that noise from the random pool's bits nor upon
      interrupt, but will rather combine a few elements along the Tx path
      that are collectively hard to predict, such as dev, skb and txq
      pointers, packet length and jiffies values. These ones are combined
      using a single round of SipHash into a single long variable that is
      mixed with the net_rand_state upon each invocation.
      
      The operation was inlined because it produces very small and efficient
      code, typically 3 xor, 2 add and 2 rol. The performance was measured
      to be the same (even very slightly better) than before the switch to
      SipHash; on a 6-core 12-thread Core i7-8700k equipped with a 40G NIC
      (i40e), the connection rate dropped from 556k/s to 555k/s while the
      SYN cookie rate grew from 5.38 Mpps to 5.45 Mpps.

      random32: make prandom_u32() output unpredictable · c51f8f88
      George Spelvin authored
      Non-cryptographic PRNGs may have great statistical properties, but
      are usually trivially predictable to someone who knows the algorithm,
      given a small sample of their output.  An LFSR like prandom_u32() is
      particularly simple, even if the sample is widely scattered bits.
      
      It turns out the network stack uses prandom_u32() for some things like
      random port numbers which it would prefer are *not* trivially predictable.
      Predictability led to a practical DNS spoofing attack.  Oops.
      
      This patch replaces the LFSR with a homebrew cryptographic PRNG based
      on the SipHash round function, which is in turn seeded with 128 bits
      of strong random key.  (The authors of SipHash have *not* been consulted
      about this abuse of their algorithm.)  Speed is prioritized over security;
      attacks are rare, while performance is always wanted.
      
      Replacing all callers of prandom_u32() is the quick fix.
      Whether to reinstate a weaker PRNG for uses which can tolerate it
      is an open question.
      
      Commit f227e3ec ("random32: update the net random state on interrupt
      and activity") was an earlier attempt at a solution.  This patch replaces
      it.

      KVM: ioapic: break infinite recursion on lazy EOI · 77377064
      Vitaly Kuznetsov authored
      During shutdown the IOAPIC trigger mode is reset to edge triggered
      while the vfio-pci INTx is still registered with a resampler.
      This allows us to get into an infinite loop:
      
      ioapic_set_irq
        -> ioapic_lazy_update_eoi
        -> kvm_ioapic_update_eoi_one
        -> kvm_notify_acked_irq
        -> kvm_notify_acked_gsi
        -> (via irq_acked fn ptr) irqfd_resampler_ack
        -> kvm_set_irq
        -> (via set fn ptr) kvm_set_ioapic_irq
        -> kvm_ioapic_set_irq
        -> ioapic_set_irq
      
      Commit 8be8f932 ("kvm: ioapic: Restrict lazy EOI update to
      edge-triggered interrupts", 2020-05-04) acknowledges that this recursion
      loop exists and tries to avoid it at the call to ioapic_lazy_update_eoi,
      but at this point the scenario is already set, we have an edge interrupt
      with resampler on the same gsi.
      
      Fortunately, the only user of irq ack notifiers (in addition to resamplefd)
      is i8254 timer interrupt reinjection.  These are edge-triggered, so in
      principle they would need the call to kvm_ioapic_update_eoi_one from
      ioapic_lazy_update_eoi, but they already disable AVIC(*), so they don't
      need the lazy EOI behavior.  Therefore, remove the call to
      kvm_ioapic_update_eoi_one from ioapic_lazy_update_eoi.
      
      This fixes CVE-2020-27152.  Note that this issue cannot happen with
      SR-IOV assigned devices because virtual functions do not have INTx,
      only MSI.

       "First of all, the adaptive voltage scaling (AVS) drivers go to new
        platform-specific locations as planned (this part was reported to have
        merge conflicts against the new arm-soc updates in linux-next).
      
        In addition to that, there are some fixes (intel_idle, intel_pstate,
        RAPL, acpi_cpufreq), the addition of on/off notifiers and idle state
        accounting support to the generic power domains (genpd) code and some
        janitorial changes all over.
      
        Specifics:
      
         - Move the AVS drivers to new platform-specific locations and get rid
           of the drivers/power/avs directory (Ulf Hansson).
      
         - Add on/off notifiers and idle state accounting support to the
           generic power domains (genpd) framework (Ulf Hansson, Lina Iyer).
      
         - Ulf will maintain the PM domain part of cpuidle-psci (Ulf Hansson).
      
         - Make intel_idle disregard ACPI _CST if it cannot use the data
           returned by that method (Mel Gorman).
      
         - Modify intel_pstate to avoid leaving useless sysfs directory
           structure behind if it cannot be registered (Chen Yu).
      
         - Fix domain detection in the RAPL power capping driver and prevent
           it from failing to enumerate the Psys RAPL domain (Zhang Rui).
      
         - Allow acpi-cpufreq to use ACPI _PSD information with Family 19 and
           later AMD chips (Wei Huang).
      
         - Update the driver assumptions comment in intel_idle and fix a
           kerneldoc comment in the runtime PM framework (Alexander Monakov,
           Bean Huo).
      
         - Avoid unnecessary resets of the cached frequency in the schedutil
           cpufreq governor to reduce overhead (Wei Wang).
      
         - Clean up the cpufreq core a bit (Viresh Kumar).

      x86/uaccess: fix code generation in put_user() · 9c5743df
      Rasmus Villemoes authored
      Quoting https://gcc.gnu.org/onlinedocs/gcc/Local-Register-Variables.html:
      
        You can define a local register variable and associate it with a
        specified register...
      
        The only supported use for this feature is to specify registers for
        input and output operands when calling Extended asm (see Extended
        Asm). This may be necessary if the constraints for a particular
        machine don't provide sufficient control to select the desired
        register.
      
      On 32-bit x86, this is used to ensure that gcc will put an 8-byte value
      into the %edx:%eax pair, while all other cases will just use the single
      register %eax (%rax on x86-64).  While the _ASM_AX actually just expands
      to "%eax", note this comment next to get_user() which does something
      very similar:
      
       * The use of _ASM_DX as the register specifier is a bit of a
       * simplification, as gcc only cares about it as the starting point
       * and not size: for a 64-bit value it will use %ecx:%edx on 32 bits
       * (%ecx being the next register in gcc's x86 register sequence), and
       * %rdx on 64 bits.
      
      However, getting this to work requires that there is no code between the
      assignment to the local register variable and its use as an input to the
      asm() which can possibly clobber any of the registers involved -
      including evaluation of the expressions making up other inputs.
      
      In the current code, the ptr expression used directly as an input may
      cause such code to be emitted.  For example, Sean Christopherson
      observed that with KASAN enabled and ptr being current->set_child_tid
      (from chedule_tail()), the load of current->set_child_tid causes a call
      to __asan_load8() to be emitted immediately prior to the __put_user_4
      call, and Naresh Kamboju reports that various mmstress tests fail on
      KASAN-enabled builds.
      
      It's also possible to synthesize a broken case without KASAN if one uses
      "foo()" as the ptr argument, with foo being some "extern u64 __user
      *foo(void);" (though I don't know if that appears in real code).
      
      Fix it by making sure ptr gets evaluated before the assignment to
      __val_pu, and add a comment that __val_pu must be the last thing
      computed before the asm() is entered.

      Merge tag 'net-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net · 3cb12d27
      Linus Torvalds authored
      Pull networking fixes from Jakub Kicinski:
       "Cross-tree/merge window issues:
      
         - rtl8150: don't incorrectly assign random MAC addresses; fix late in
           the 5.9 cycle started depending on a return code from a function
           which changed with the 5.10 PR from the usb subsystem
      
        Current release regressions:
      
         - Revert "virtio-net: ethtool configurable RXCSUM", it was causing
           crashes at probe when control vq was not negotiated/available
      
        Previous release regressions:
      
         - ixgbe: fix probing of multi-port 10 Gigabit Intel NICs with an MDIO
           bus, only first device would be probed correctly
      
         - nexthop: Fix performance regression in nexthop deletion by
           effectively switching from recently added synchronize_rcu() to
           synchronize_rcu_expedited()
      
         - netsec: ignore 'phy-mode' device property on ACPI systems; the
           property is not populated correctly by the firmware, but firmware
           configures the PHY so just keep boot settings
      
        Previous releases - always broken:
      
         - tcp: fix to update snd_wl1 in bulk receiver fast path, addressing
           bulk transfers getting "stuck"
      
         - icmp: randomize the global rate limiter to prevent attackers from
           getting useful signal
      
         - r8169: fix operation under forced interrupt threading, make the
           driver always use hard irqs, even on RT, given the handler is light
           and only wants to schedule napi (and do so through a _irqoff()
           variant, preferably)
      
         - bpf: Enforce pointer id generation for all may-be-null register
           type to avoid pointers erroneously getting marked as null-checked
      
         - tipc: re-configure queue limit for broadcast link
      
         - net/sched: act_tunnel_key: fix OOB write in case of IPv6 ERSPAN
           tunnels
      
         - fix various issues in chelsio inline tls driver
      
        Misc:
      
         - bpf: improve just-added bpf_redirect_neigh() helper api to support
           supplying nexthop by the caller - in case BPF program has already
           done a lookup we can avoid doing another one
      
         - remove unnecessary break statements
      
         - make MCTCP not select IPV6, but rather depend on it"
