      nvram: Fix write beyond end condition; prove to gcc copy is safe · a01c7800
      H. Peter Anvin authored
      In nvram_write, first of all, correctly handle the case where the file
      pointer is already beyond the end; we should return EOF in that case.
      
      Second, make the logic a bit more explicit so that gcc can statically
      prove that the copy_from_user() is safe.  Once the condition of the
      beyond-end filepointer is eliminated, the copy is safe but gcc can't
      prove it, causing build failures for i386 allyesconfig.
      
      Third, eliminate the entirely superfluous variable "len", and just use
      the passed-in variable "count" instead.

      mm: Adjust do_pages_stat() so gcc can see copy_from_user() is safe · b9255850
      H. Peter Anvin authored
      Slightly adjust the logic for determining the size of the
      copy_form_user() in do_pages_stat(); with this change, gcc can see
      that the copying is safe.
      
      Without this, we get a build error for i386 allyesconfig:
      
      /home/hpa/kernel/linux-2.6-tip.urgent/arch/x86/include/asm/uaccess_32.h:213:
      error: call to ‘copy_from_user_overflow’ declared with attribute
      error: copy_from_user() buffer size is not provably correct
      
      Unlike an earlier patch from Arjan, this doesn't introduce new
      variables; merely reshuffles the compare so that gcc can see that an
      overflow cannot happen.

      x86: Limit the number of processor bootup messages · 2eaad1fd
      Mike Travis authored
      When there are a large number of processors in a system, there
      is an excessive amount of messages sent to the system console.
      It's estimated that with 4096 processors in a system, and the
      console baudrate set to 56K, the startup messages will take
      about 84 minutes to clear the serial port.
      
      This set of patches limits the number of repetitious messages
      which contain no additional information.  Much of this information
      is obtainable from the /proc and /sysfs.   Some of the messages
      are also sent to the kernel log buffer as KERN_DEBUG messages so
      dmesg can be used to examine more closely any details specific to
      a problem.
      
      The new cpu bootup sequence for system_state == SYSTEM_BOOTING:
      
      Booting Node   0, Processors  #1 #2 #3 #4 #5 #6 #7 Ok.
      Booting Node   1, Processors  #8 #9 #10 #11 #12 #13 #14 #15 Ok.
      ...
      Booting Node   3, Processors  #56 #57 #58 #59 #60 #61 #62 #63 Ok.
      Brought up 64 CPUs
      
      After the system is running, a single line boot message is displayed
      when CPU's are hotplugged on:
      
          Booting Node %d Processor %d APIC 0x%x
      
      Status of the following lines:
      
          CPU: Physical Processor ID:		printed once (for boot cpu)
          CPU: Processor Core ID:		printed once (for boot cpu)
          CPU: Hyper-Threading is disabled	printed once (for boot cpu)
          CPU: Thermal monitoring enabled	printed once (for boot cpu)
          CPU %d/0x%x -> Node %d:		removed
          CPU %d is now offline:		only if system_state == RUNNING

      x86, msr: Add support for non-contiguous cpumasks · 50542251
      Borislav Petkov authored
      The current rd/wrmsr_on_cpus helpers assume that the supplied
      cpumasks are contiguous. However, there are machines out there
      like some K8 multinode Opterons which have a non-contiguous core
      enumeration on each node (e.g. cores 0,2 on node 0 instead of 0,1), see
      http://www.gossamer-threads.com/lists/linux/kernel/1160268.
      
      This patch fixes out-of-bounds writes (see URL above) by adding per-CPU
      msr structs which are used on the respective cores.
      
      Additionally, two helpers, msrs_{alloc,free}, are provided for use by
      the callers of the MSR accessors.

      It turns out the BIOS is using the first 64k for mptable,
      without reserving it.
      
      So try to find good range for the real-mode trampoline instead of
      hard coding it, in case some bios tries to use that range for sth.

      x86, AMD: Fix stale cpuid4_info shared_map data in shared_cpu_map cpumasks · ebb682f5
      Prarit Bhargava authored
      The per_cpu cpuid4_info shared_map can contain stale data when CPUs are added
      and removed.
      
      The stale data can lead to a NULL pointer derefernce panic on a remove of a
      CPU that has had siblings previously removed.
      
      This patch resolves the panic by verifying a cpu is actually online before
      adding it to the shared_cpu_map, only examining cpus that are part of
      the same lower level cache, and by updating other siblings lowest level cache
      maps when a cpu is added.

      Boaz Harrosh authored
      This patch changes on-disk format, it is accompanied with a parallel
      patch to mkfs.exofs that enables multi-device capabilities.
      
      After this patch, old exofs will refuse to mount a new formatted FS and
      new exofs will refuse an old format. This is done by moving the magic
      field offset inside the FSCB. A new FSCB *version* field was added. In
      the future, exofs will refuse to mount unmatched FSCB version. To
      up-grade or down-grade an exofs one must use mkfs.exofs --upgrade option
      before mounting.
      
      Introduced, a new object that contains a *device-table*. This object
      contains the default *data-map* and a linear array of devices
      information, which identifies the devices used in the filesystem. This
      object is only written to offline by mkfs.exofs. This is why it is kept
      separate from the FSCB, since the later is written to while mounted.
      
      Same partition number, same object number is used on all devices only
      the device varies.
      
      * define the new format, then load the device table on mount time make
        sure every thing is supported.
      
      * Change I/O engine to now support Mirror IO, .i.e write same data
        to multiple devices, read from a random device to spread the
        read-load from multiple clients (TODO: stripe read)
      
      Implementation notes:
       A few points introduced in previous patch should be mentioned here:
      
      * Special care was made so absolutlly all operation that have any chance
        of failing are done before any osd-request is executed. This is to
        minimize the need for a data consistency recovery, to only real IO
        errors.
      
      * Each IO state has a kref. It starts at 1, any osd-request executed
        will increment the kref, finally when all are executed the first ref
        is dropped. At IO-done, each request completion decrements the kref,
        the last one to return executes the internal _last_io() routine.
        _last_io() will call the registered io_state_done. On sync mode a
        caller does not supply a done method, indicating a synchronous
        request, the caller is put to sleep and a special io_state_done is
        registered that will awaken the caller. Though also in sync mode all
        operations are executed in parallel.

      exofs: Move all operations to an io_engine · 06886a5a
      Boaz Harrosh authored
      In anticipation for multi-device operations, we separate osd operations
      into an abstract I/O API. Currently only one device is used but later
      when adding more devices, we will drive all devices in parallel according
      to a "data_map" that describes how data is arranged on multiple devices.
      The file system level operates, like before, as if there is one object
      (inode-number) and an i_size. The io engine will split this to the same
      object-number but on multiple device.
      
      At first we introduce Mirror (raid 1) layout. But at the final outcome
      we intend to fully implement the pNFS-Objects data-map, including
      raid 0,4,5,6 over mirrored devices, over multiple device-groups. And
      more. See: http://tools.ietf.org/html/draft-ietf-nfsv4-pnfs-obj-12
      
      * Define an io_state based API for accessing osd storage devices
        in an abstract way.
        Usage:
      	First a caller allocates an io state with:
      		exofs_get_io_state(struct exofs_sb_info *sbi,
      				   struct exofs_io_state** ios);
      
      	Then calles one of:
      		exofs_sbi_create(struct exofs_io_state *ios);
      		exofs_sbi_remove(struct exofs_io_state *ios);
      		exofs_sbi_write(struct exofs_io_state *ios);
      		exofs_sbi_read(struct exofs_io_state *ios);
      		exofs_oi_truncate(struct exofs_i_info *oi, u64 new_len);
      
      	And when done
      		exofs_put_io_state(struct exofs_io_state *ios);
      
      * Convert all source files to use this new API
      * Convert from bio_alloc to bio_kmalloc
      * In io engine we make use of the now fixed osd_req_decode_sense
      
      There are no functional changes or on disk additions after this patch.

      exofs: move osd.c to ios.c · 8ce9bdd1
      Boaz Harrosh authored
      If I do a "git mv" together with a massive code change
      and commit in one patch, git looses the rename and
      records a delete/new instead. This is bad because I want
      a rename recorded so later rebased/cherry-picked patches
      to the old name will work. Also the --follow is lost.

      exofs: Prints on mount and unmout · 19fe294f
      Boaz Harrosh authored
      It is important to print in the logs when a filesystem was
      mounted and eventually unmounted.
      
      Print the osd-device's osd_name and pid the FS was
      mounted/unmounted on.
      
      TODO: How to also print the namespace path the filesystem was
            mounted on?

      Iner-loops printing is converted to EXOFS_DBG2 which is #defined
      to nothing.
      
      It is now almost bareable to just leave debug-on. Every operation
      is printed once, with most relevant info (I hope).
