      xen/grant-table: correctly initialize grant table version 1 · d0b4d64a
      Matt Wilson authored
      Commit 85ff6acb (xen/granttable: Grant
      tables V2 implementation) changed the GREFS_PER_GRANT_FRAME macro from
      a constant to a conditional expression. The expression depends on
      grant_table_version being appropriately set. Unfortunately, at init
      time grant_table_version will be 0. The GREFS_PER_GRANT_FRAME
      conditional expression checks for "grant_table_version == 1", and
      therefore returns the number of grant references per frame for v2.
      
      This causes gnttab_init() to allocate fewer pages for gnttab_list, as
      a frame can old half the number of v2 entries than v1 entries. After
      gnttab_resume() is called, grant_table_version is appropriately
      set. nr_init_grefs will then be miscalculated and gnttab_free_count
      will hold a value larger than the actual number of free gref entries.
      
      If a guest is heavily utilizing improperly initialized v1 grant
      tables, memory corruption can occur. One common manifestation is
      corruption of the vmalloc list, resulting in a poisoned pointer
      derefrence when accessing /proc/meminfo or /proc/vmallocinfo:
      
      [   40.770064] BUG: unable to handle kernel paging request at 0000200200001407
      [   40.770083] IP: [<ffffffff811a6fb0>] get_vmalloc_info+0x70/0x110
      [   40.770102] PGD 0
      [   40.770107] Oops: 0000 [#1] SMP
      [   40.770114] CPU 10
      
      This patch introduces a static variable, grefs_per_grant_frame, to
      cache the calculated value. gnttab_init() now calls
      gnttab_request_version() early so that grant_table_version and
      grefs_per_grant_frame can be appropriately set. A few BUG_ON()s have
      been added to prevent this type of bug from reoccurring in the future.

      xen/acpi: revert pad config check in xen_check_mwait · e3aa4e61
      Liu, Jinsong authored
      With Xen acpi pad logic added into kernel, we can now revert xen mwait related
      patch df88b2d9 ("xen/enlighten: Disable
      MWAIT_LEAF so that acpi-pad won't be loaded. "). The reason is, when running under
      newer Xen platform, Xen pad driver would be early loaded, so native pad driver
      would fail to be loaded, and hence no mwait/monitor #UD risk again.
      
      Another point is, only Xen4.2 or later support Xen acpi pad, so we won't expose
      mwait cpuid capability when running under older Xen platform.

      xen/acpi: ACPI PAD driver · 92e3229d
      Liu, Jinsong authored
      PAD is acpi Processor Aggregator Device which provides a control point
      that enables the platform to perform specific processor configuration
      and control that applies to all processors in the platform.
      
      This patch is to implement Xen acpi pad logic. When running under Xen
      virt platform, native pad driver would not work. Instead Xen pad driver,
      a self-contained and thin logic level, would take over acpi pad logic.
      
      When acpi pad notify OSPM, xen pad logic intercept and parse _PUR object
      to get the expected idle cpu number, and then hypercall to hypervisor.
      Xen hypervisor would then do the rest work, say, core parking, to idle
      specific number of cpus on its own policy.

      xen-pciback: reject out of range inputs · b3e40b72
      Jan Beulich authored
      This add checks for out of range numbers (including in cases where the
      folding of slot and function into a single value could yield false
      matches).
      
      It also removes the bogus field width restrictions in str_to_quirk() -
      nowhere else in the driver this is being done, and hence this function
      could reject input the equivalent of which would be happily accepted
      in other places (in particular, "0x" prefixes causing the effective
      width of the actual number to be either zero or less than what would be
      required to cover the full range of valid values). Note that for the
      moment this second part is cosmetic only, as the kernel's sscanf()
      currently ignores the field widths, but a patch to overcome this is on
      its way.

      xen-pciback: simplify and tighten parsing of device IDs · 5b71fbdc
      Jan Beulich authored
      Now that at least one of the conformance problems of the kernel's
      sscanf() was addressed (commit da99075c),
      we can improve the parsing done in xen-pciback both in terms of code
      readability and correctness (in particular properly rejecting input
      strings not well formed).

      xen PVonHVM: use E820_Reserved area for shared_info · 9d02b43d
      Olaf Hering authored
      This is a respin of 00e37bdb
      ("xen PVonHVM: move shared_info to MMIO before kexec").
      
      Currently kexec in a PVonHVM guest fails with a triple fault because the
      new kernel overwrites the shared info page. The exact failure depends on
      the size of the kernel image. This patch moves the pfn from RAM into an
      E820 reserved memory area.
      
      The pfn containing the shared_info is located somewhere in RAM. This will
      cause trouble if the current kernel is doing a kexec boot into a new
      kernel. The new kernel (and its startup code) can not know where the pfn
      is, so it can not reserve the page. The hypervisor will continue to update
      the pfn, and as a result memory corruption occours in the new kernel.
      
      The toolstack marks the memory area FC000000-FFFFFFFF as reserved in the
      E820 map. Within that range newer toolstacks (4.3+) will keep 1MB
      starting from FE700000 as reserved for guest use. Older Xen4 toolstacks
      will usually not allocate areas up to FE700000, so FE700000 is expected
      to work also with older toolstacks.
      
      In Xen3 there is no reserved area at a fixed location. If the guest is
      started on such old hosts the shared_info page will be placed in RAM. As
      a result kexec can not be used.

      Lock splice_read and splice_write functions · 1a25b1c4

      Functions generic_file_splice_read and generic_file_splice_write access
      the pagecache directly. For block devices these functions must be locked

      This patch is an additional fix for commit b87570f5 ("Fix a crash
      when block device is read and block size is changed at the same time")
      that locked aio_read, aio_write and mmap against block size change.

      percpu-rw-semaphores: use rcu_read_lock_sched · 1bf11c53
      Mikulas Patocka authored
      Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched
      instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu.
      
      This is an optimization. The RCU-protected region is very small, so
      there will be no latency problems if we disable preempt in this region.
      
      So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates
      to preempt_disable / preempt_disable. It is smaller (and supposedly
      faster) than preemptible rcu_read_lock / rcu_read_unlock.

       "Here are a bunch of USB fixes for the 3.7-rc tree.
      
        There's a lot of small USB serial driver fixes, and one larger one
        (the mos7840 driver changes are mostly just moving code around to fix
        problems.) Thanks to Johan Hovold for finding the problems and fixing
        them all up.
      
        Other than those, there is the usual new device ids, xhci bugfixes,
        and gadget driver fixes, nothing out of the ordinary.
