      Make file credentials available to the seqfile interfaces · 34dbbcdb
      Linus Torvalds authored
      A lot of seqfile users seem to be using things like %pK that uses the
      credentials of the current process, but that is actually completely
      wrong for filesystem interfaces.
      
      The unix semantics for permission checking files is to check permissions
      at _open_ time, not at read or write time, and that is not just a small
      detail: passing off stdin/stdout/stderr to a suid application and making
      the actual IO happen in privileged context is a classic exploit
      technique.
      
      So if we want to be able to look at permissions at read time, we need to
      use the file open credentials, not the current ones.  Normal file
      accesses can just use "f_cred" (or any of the helper functions that do
      that, like file_ns_capable()), but the seqfile interfaces do not have
      any such options.
      
      It turns out that seq_file _does_ save away the user_ns information of
      the file, though.  Since user_ns is just part of the full credential
      information, replace that special case with saving off the cred pointer
      instead, and suddenly seq_file has all the permission information it
      needs.

      This reverts commit c4004b02.
      
      Sadly, my hope that nobody would actually use the special kernel entries
      in /proc/iomem were dashed by kexec.  Which reads /proc/iomem explicitly
      to find the kernel base address.  Nasty.
      
      Anyway, that means we can't do the sane and simple thing and just remove
      the entries, and we'll instead have to mask them out based on permissions.

      Revert "ext4: allow readdir()'s of large empty directories to be interrupted" · 9f2394c9
      Linus Torvalds authored
      This reverts commit 1028b55b.
      
      It's broken: it makes ext4 return an error at an invalid point, causing
      the readdir wrappers to write the the position of the last successful
      directory entry into the position field, which means that the next
      readdir will now return that last successful entry _again_.
      
      You can only return fatal errors (that terminate the readdir directory
      walk) from within the filesystem readdir functions, the "normal" errors
      (that happen when the readdir buffer fills up, for example) happen in
      the iterorator where we know the position of the actual failing entry.
      
      I do have a very different patch that does the "signal_pending()"
      handling inside the iterator function where it is allowable, but while
      that one passes all the sanity checks, I screwed up something like four
      times while emailing it out, so I'm not going to commit it today.
      
      So my track record is not good enough, and the stars will have to align
      better before that one gets committed.  And it would be good to get some
      review too, of course, since celestial alignments are always an iffy
      debugging model.
      
      IOW, let's just revert the commit that caused the problem for now.

      kvm: x86: do not leak guest xcr0 into host interrupt handlers · fc5b7f3b
      David Matlack authored
      An interrupt handler that uses the fpu can kill a KVM VM, if it runs
      under the following conditions:
       - the guest's xcr0 register is loaded on the cpu
       - the guest's fpu context is not loaded
       - the host is using eagerfpu
      
      Note that the guest's xcr0 register and fpu context are not loaded as
      part of the atomic world switch into "guest mode". They are loaded by
      KVM while the cpu is still in "host mode".
      
      Usage of the fpu in interrupt context is gated by irq_fpu_usable(). The
      interrupt handler will look something like this:
      
      if (irq_fpu_usable()) {
              kernel_fpu_begin();
      
              [... code that uses the fpu ...]
      
              kernel_fpu_end();
      }
      
      As long as the guest's fpu is not loaded and the host is using eager
      fpu, irq_fpu_usable() returns true (interrupted_kernel_fpu_idle()
      returns true). The interrupt handler proceeds to use the fpu with
      the guest's xcr0 live.
      
      kernel_fpu_begin() saves the current fpu context. If this uses
      XSAVE[OPT], it may leave the xsave area in an undesirable state.
      According to the SDM, during XSAVE bit i of XSTATE_BV is not modified
      if bit i is 0 in xcr0. So it's possible that XSTATE_BV[i] == 1 and
      xcr0[i] == 0 following an XSAVE.
      
      kernel_fpu_end() restores the fpu context. Now if any bit i in
      XSTATE_BV == 1 while xcr0[i] == 0, XRSTOR generates a #GP. The
      fault is trapped and SIGSEGV is delivered to the current process.
      
      Only pre-4.2 kernels appear to be vulnerable to this sequence of
      events. Commit 653f52c3 ("kvm,x86: load guest FPU context more eagerly")
      from 4.2 forces the guest's fpu to always be loaded on eagerfpu hosts.
      
      This patch fixes the bug by keeping the host's xcr0 loaded outside
      of the interrupts-disabled region where KVM switches into guest mode.

        Core fixes:
      
         - Defer GPIO device setup until after gpiolib is initialized.
      
           It turns out that a few very tightly integrated GPIO platform
           drivers initialize so early (befor core_initcall()) so that the
           gpiolib isn't even initialized itself.  That limits what the
           library can do, and we cannot reference uninitialized fields until
           later.
      
           Defer some of the initialization until right after the gpiolib is
           initialized in these (rare) cases.
      
         - As a consequence: do not use devm_* resources when allocating the
           states in the initial set-up of the gpiochip.
      
        Driver fixes:
      
         - In ACPI retrieveal: ignore GpioInt when looking for output GPIOs.
      
         - Fix legacy builds on the PXA without a backing pin controller.

        sd being overly chatty on revalidation (causing excess log increases).
        A VPD issue which could crash USB devices because they seem very

      Pull power management and ACPI fixes from Rafael Wysocki:
       "Fixes for some issues discovered after recent changes and for some
        that have just been found lately regardless of those changes
        (intel_pstate, intel_idle, PM core, mailbox/pcc, turbostat) plus
        support for some new CPU models (intel_idle, Intel RAPL driver,
        turbostat) and documentation updates (intel_pstate, PM core).
      
        Specifics:
      
         - intel_pstate fixes for two issues exposed by the recent switch over
           from using timers and for one issue introduced during the 4.4 cycle
           plus new comments describing data structures used by the driver
           (Rafael Wysocki, Srinivas Pandruvada).
      
         - intel_idle fixes related to CPU offline/online (Richard Cochran).
      
         - intel_idle support (new CPU IDs and state definitions mostly) for
           Skylake-X and Kabylake processors (Len Brown).
      
         - PCC mailbox driver fix for an out-of-bounds memory access that may
           cause the kernel to panic() (Shanker Donthineni).
      
         - New (missing) CPU ID for one apparently overlooked Haswell model in
           the Intel RAPL power capping driver (Srinivas Pandruvada).
      
         - Fix for the PM core's wakeup IRQs framework to make it work after
           wakeup settings reconfiguration from sysfs (Grygorii Strashko).
      
         - Runtime PM documentation update to make it describe what needs to
           be done during device removal more precisely (Krzysztof Kozlowski).
      
         - Stale comment removal cleanup in the cpufreq-dt driver (Viresh
           Kumar).
      
         - turbostat utility fixes and support for Broxton, Skylake-X and
           Kabylake processors (Len Brown)"
