      [TG3]: 40-bit DMA workaround part 2 · 4a29cc2e
      Michael Chan authored
      
      
      The 40-bit DMA workaround recently implemented for 5714, 5715, and
      5780 needs to be expanded because there may be other tg3 devices
      behind the EPB Express to PCIX bridge in the 5780 class device.
      
      For example, some 4-port card or mother board designs have 5704 behind
      the 5714.
      
      All devices behind the EPB require the 40-bit DMA workaround.
      
      Thanks to Chris Elmquist again for reporting the problem and testing
      the patch.

      [AX.25]: Fix potencial memory hole. · c7c694d1
      Ralf Baechle DL5RB authored
      
      
      If the AX.25 dialect chosen by the sysadmin is set to DAMA master / 3
      (or DAMA slave / 2, if CONFIG_AX25_DAMA_SLAVE=n) ax25_kick() will fall
      through the switch statement without calling ax25_send_iframe() or any
      other function that would eventually free skbn thus leaking the packet.
      
      Fix by restricting the sysctl inferface to allow only actually supported
      AX.25 dialects.
      
      The system administration mistake needed for this to happen is rather
      unlikely, so this is an uncritical hole.
      
      Coverity #651.

      It is broken, the condition is checked out of socket lock. It is
      wonderful the bug survived for so long time.

      [PATCH] fix free swap cache latency · 6f5e6b9e
      Hugh Dickins authored
      
      
      Lee Revell reported 28ms latency when process with lots of swapped memory
      exits.
      
      2.6.15 introduced a latency regression when unmapping: in accounting the
      zap_work latency breaker, pte_none counted 1, pte_present PAGE_SIZE, but a
      swap entry counted nothing at all.  We think of pages present as the slow
      case, but Lee's trace shows that free_swap_and_cache's radix tree lookup
      can make a lot of work - and we could have been doing it many thousands of
      times without a latency break.
      
      Move the zap_work update up to account swap entries like pages present.
      This does account non-linear pte_file entries, and unmap_mapping_range
      skipping over swap entries, by the same amount even though they're quick:
      but neither of those cases deserves complicating the code (and they're
      treated no worse than they were in 2.6.14).

      [PATCH] kbuild: fix buffer overflow in modpost · 7670f023
      Sam Ravnborg authored
      
      
      Jiri Benc <jbenc@suse.cz> reported that modpost would stop with SIGABRT if
      used with long filepaths.
      The error looked like:
      >   Building modules, stage 2.
      >   MODPOST
      > *** glibc detected *** scripts/mod/modpost: realloc(): invalid next size:
      +0x0809f588 ***
      > [...]
      
      Fix this by allocating at least the required memory + SZ bytes each time.
      Before we sometimes ended up allocating too little memory resuting in the
      glibc detected bug above.  Based on patch originally submitted by: Jiri

      [PATCH] nfsservctl(): remove user-triggerable printk · 85c6932e
      Peter Staubach authored
      
      
      A user can use nfsservctl() to spam the logs.
      
      This can happen because the arguments to the nfsservctl() system call are
      versioned.  This is a good thing.  However, when a bad version is detected,
      the kernel prints a message and then returns an error.

      [PATCH] fix race in pagevec_strip? · 5b40dc78
      Christoph Lameter authored
      
      
      We can call try_to_release_page() with PagePrivate off and a valid
      page->mapping This may cause all sorts of trouble for the filesystem
      *_releasepage() handlers.  XFS bombs out in that case.
      
      Lock the page before checking for page private.

      [PATCH] dm stripe: Fix bounds · 8ba32fde
      Kevin Corry authored
      
      
      The dm-stripe target currently does not enforce that the size of a stripe
      device be a multiple of the chunk-size.  Under certain conditions, this can
      lead to I/O requests going off the end of an underlying device.  This
      test-case shows one example.
      
      echo "0 100 linear /dev/hdb1 0" | dmsetup create linear0
      echo "0 100 linear /dev/hdb1 100" | dmsetup create linear1
      echo "0 200 striped 2 32 /dev/mapper/linear0 0 /dev/mapper/linear1 0" | \
         dmsetup create stripe0
      dd if=/dev/zero of=/dev/mapper/stripe0 bs=1k
      
      This will produce the output:
      dd: writing '/dev/mapper/stripe0': Input/output error
      97+0 records in
      96+0 records out
      
      And in the kernel log will be:
      attempt to access beyond end of device
      dm-0: rw=0, want=104, limit=100
      
      The patch will check that the table size is a multiple of the stripe
      chunk-size when the table is created, which will prevent the above striped
      device from being created.
      
      This should not affect tools like LVM or EVMS, since in all the cases I can
      think of, striped devices are always created with the sizes being a
      multiple of the chunk-size.
      
      The size of a stripe device must be a multiple of its chunk-size.
      
      (akpm: that typecast is quite gratuitous)
