      ext3: fix broken handling of EXT3_STATE_NEW · de329820
      Linus Torvalds authored
      In commit 9df93939 ("ext3: Use bitops to read/modify
      EXT3_I(inode)->i_state") ext3 changed its internal 'i_state' variable to
      use bitops for its state handling.  However, unline the same ext4
      change, it didn't actually change the name of the field when it changed
      the semantics of it.
      
      As a result, an old use of 'i_state' remained in fs/ext3/ialloc.c that
      initialized the field to EXT3_STATE_NEW.  And that does not work
      _at_all_ when we're now working with individually named bits rather than
      values that get masked.  So the code tried to mark the state to be new,
      but in actual fact set the field to EXT3_STATE_JDATA.  Which makes no
      sense at all, and screws up all the code that checks whether the inode
      was newly allocated.
      
      In particular, it made the xattr code unhappy, and caused various random
      behavior, like apparently
      
      	https://bugzilla.redhat.com/show_bug.cgi?id=577911
      
      So fix the initialization, and rename the field to match ext4 so that we
      don't have this happen again.

      r8169: offical fix for CVE-2009-4537 (overlength frame DMAs) · c0cd884a
      Neil Horman authored
      Official patch to fix the r8169 frame length check error.
      
      Based on this initial thread:
      http://marc.info/?l=linux-netdev&m=126202972828626&w=1
      This is the official patch to fix the frame length problems in the r8169
      driver.  As noted in the previous thread, while this patch incurs a performance
      hit on the driver, its possible to improve performance dynamically by updating
      the mtu and rx_copybreak values at runtime to return performance to what it was
      for those NICS which are unaffected by the ideosyncracy (if there are any).
      
      Summary:
      
          A while back Eric submitted a patch for r8169 in which the proper
      allocated frame size was written to RXMaxSize to prevent the NIC from dmaing too
      much data.  This was done in commit fdd7b4c3.  A
      long time prior to that however, Francois posted
      126fa4b9, which expiclitly disabled the MaxSize
      setting due to the fact that the hardware behaved in odd ways when overlong
      frames were received on NIC's supported by this driver.  This was mentioned in a
      security conference recently:
      http://events.ccc.de/congress/2009/Fahrplan//events/3596.en.html
      
      It seems that if we can't enable frame size filtering, then, as Eric correctly
      noticed, we can find ourselves DMA-ing too much data to a buffer, causing
      corruption.  As a result is seems that we are forced to allocate a frame which
      is ready to handle a maximally sized receive.
      
      This obviously has performance issues with it, so to mitigate that issue, this
      patch does two things:
      
      1) Raises the copybreak value to the frame allocation size, which should force
      appropriately sized packets to get allocated on rx, rather than a full new 16k
      buffer.
      
      2) This patch only disables frame filtering initially (i.e., during the NIC
      open), changing the MTU results in ring buffer allocation of a size in relation
      to the new mtu (along with a warning indicating that this is dangerous).
      
      Because of item (2), individuals who can't cope with the performance hit (or can
      otherwise filter frames to prevent the bug), or who have hardware they are sure
      is unaffected by this issue, can manually lower the copybreak and reset the mtu
      such that performance is restored easily.

      sparc64: Properly truncate pt_regs framepointer in perf callback. · 9e8307ec
      David S. Miller authored
      For 32-bit processes, we save the full 64-bits of the regs in pt_regs.
      
      But unlike when the userspace actually does load and store
      instructions, the top 32-bits don't get automatically truncated by the
      cpu in kernel mode (because the kernel doesn't execute with PSTATE_AM
      address masking enabled).
      
      So we have to do it by hand.

      x86: Make sure free_init_pages() frees pages on page boundary · c967da6a
      Yinghai Lu authored
      When CONFIG_NO_BOOTMEM=y, it could use memory more effiently, or
      in a more compact fashion.
      
      Example:
      
       Allocated new RAMDISK: 00ec2000 - 0248ce57
       Move RAMDISK from 000000002ea04000 - 000000002ffcee56 to 00ec2000 - 0248ce56
      
      The new RAMDISK's end is not page aligned.
      Last page could be shared with other users.
      
      When free_init_pages are called for initrd or .init, the page
      could be freed and we could corrupt other data.
      
      code segment in free_init_pages():
      
       |        for (; addr < end; addr += PAGE_SIZE) {
       |                ClearPageReserved(virt_to_page(addr));
       |                init_page_count(virt_to_page(addr));
       |                memset((void *)(addr & ~(PAGE_SIZE-1)),
       |                        POISON_FREE_INITMEM, PAGE_SIZE);
       |                free_page(addr);
       |                totalram_pages++;
       |        }
      
      last half page could be used as one whole free page.
      
      So page align the boundaries.
      
      -v2: make the original initramdisk to be aligned, according to
           Johannes, otherwise we have the chance to lose one page.
           we still need to keep initrd_end not aligned, otherwise it could
           confuse decompressor.
      -v3: change to WARN_ON instead, suggested by Johannes.
      -v4: use PAGE_ALIGN, suggested by Johannes.
           We may fix that macro name later to PAGE_ALIGN_UP, and PAGE_ALIGN_DOWN
           Add comments about assuming ramdisk start is aligned
           in relocate_initrd(), change to re get ramdisk_image instead of save it
           to make diff smaller. Add warning for wrong range, suggested by Johannes.
      -v6: remove one WARN()
           We need to align beginning in free_init_pages()
           do not copy more than ramdisk_size, noticed by Johannes
