      x86/ldt: Make modify_ldt synchronous · 37868fe1
      Andy Lutomirski authored
      modify_ldt() has questionable locking and does not synchronize
      threads.  Improve it: redesign the locking and synchronize all
      threads' LDTs using an IPI on all modifications.
      
      This will dramatically slow down modify_ldt in multithreaded
      programs, but there shouldn't be any multithreaded programs that
      care about modify_ldt's performance in the first place.
      
      This fixes some fallout from the CVE-2015-5157 fixes.

      x86/xen: Probe target addresses in set_aliased_prot() before the hypercall · aa1acff3
      Andy Lutomirski authored
      The update_va_mapping hypercall can fail if the VA isn't present
      in the guest's page tables.  Under certain loads, this can
      result in an OOPS when the target address is in unpopulated vmap
      space.
      
      While we're at it, add comments to help explain what's going on.
      
      This isn't a great long-term fix.  This code should probably be
      changed to use something like set_memory_ro.

      x86/irq: Use the caller provided polarity setting in mp_check_pin_attr() · 646c4b75
      Jiang Liu authored
      Commit d32932d0 ("x86/irq: Convert IOAPIC to use hierarchical
      irqdomain interfaces") introduced a regression which causes
      malfunction of interrupt lines.
      
      The reason is that the conversion of mp_check_pin_attr() missed to
      update the polarity selection of the interrupt pin with the caller
      provided setting and instead uses a stale attribute value. That in
      turn results in chosing the wrong interrupt flow handler.
      
      Use the caller supplied setting to configure the pin correctly which
      also choses the correct interrupt flow handler.
      
      This restores the original behaviour and on the affected
      machine/driver (Surface Pro 3, i2c controller) all IOAPIC IRQ
      configuration are identical to v4.1.

      Ricardo Neri authored
      Even though it is documented how to specifiy efi parameters, it is
      possible to cause a kernel panic due to a dereference of a NULL pointer when
      parsing such parameters if "efi" alone is given:

      This panic is not reproducible with "efi=" as this will result in a non-NULL
      zero-length string.
      
      Thus, verify that the pointer to the parameter string is not NULL. This is
      consistent with other parameter-parsing functions which check for NULL pointers.

      x86/efi: Use all 64 bit of efi_memmap in setup_e820() · 7cc03e48
      Dmitry Skorodumov authored
      The efi_info structure stores low 32 bits of memory map
      in efi_memmap and high 32 bits in efi_memmap_hi.
      
      While constructing pointer in the setup_e820(), need
      to take into account all 64 bit of the pointer.
      
      It is because on 64bit machine the function
      efi_get_memory_map() may return full 64bit pointer and before
      the patch that pointer was truncated.
      
      The issue is triggered on Parallles virtual machine and
      fixed with this patch.

      "No, the default values need to be set to the fallback types,
       i.e. minimal supported mode.  For WC and WT, UC is the fallback type.
      
       When PAT is disabled, pat_init() does update the tables below to
       enable WT per the default BIOS setup.  However, when PAT is enabled,
       but CPU has PAT -errata, WT falls back to UC per the default values."

      The CQM task events are not safe to be called from within interrupt
      context because they require performing an IPI to read the counter value
      on all sockets. And performing IPIs from within IRQ context is a
      "no-no".
      
      Make do with the last read counter value currently event in
      event->count when we're invoked in this context.
