      char: mxser, fix ISA board lookup · 96050dfb
      Peter Botha authored
      
      
      There's a bug in the mxser kernel module that still appears in the
      2.6.29.4 kernel.
      
      mxser_get_ISA_conf takes a ioaddress as its first argument, by passing the
      not of the ioaddr, you're effectively passing 0 which means it won't be
      able to talk to an ISA card.  I have tested this, and removing the !
      fixes the problem.

      jbd: fix race in buffer processing in commit code · a61d90d7
      Jan Kara authored
      
      
      In commit code, we scan buffers attached to a transaction.  During this
      scan, we sometimes have to drop j_list_lock and then we recheck whether
      the journal buffer head didn't get freed by journal_try_to_free_buffers().
       But checking for buffer_jbd(bh) isn't enough because a new journal head
      could get attached to our buffer head.  So add a check whether the journal
      head remained the same and whether it's still at the same transaction and
      list.
      
      This is a nasty bug and can cause problems like memory corruption (use after
      free) or trigger various assertions in JBD code (observed).

      autofs4: remove hashed check in validate_wait() · 463aea1a
      Ian Kent authored
      
      
      The recent ->lookup() deadlock correction required the directory inode
      mutex to be dropped while waiting for expire completion.  We were
      concerned about side effects from this change and one has been identified.
      
      I saw several error messages.
      
      They cause autofs to become quite confused and don't really point to the
      actual problem.
      
      Things like:
      
      handle_packet_missing_direct:1376: can't find map entry for (43,1827932)
      
      which is usually totally fatal (although in this case it wouldn't be
      except that I treat is as such because it normally is).
      
      do_mount_direct: direct trigger not valid or already mounted
      /test/nested/g3c/s1/ss1
      
      which is recoverable, however if this problem is at play it can cause
      autofs to become quite confused as to the dependencies in the mount tree
      because mount triggers end up mounted multiple times.  It's hard to
      accurately check for this over mounting case and automount shouldn't need
      to if the kernel module is doing its job.
      
      There was one other message, similar in consequence of this last one but I
      can't locate a log example just now.
      
      When checking if a mount has already completed prior to adding a new mount
      request to the wait queue we check if the dentry is hashed and, if so, if
      it is a mount point.  But, if a mount successfully completed while we
      slept on the wait queue mutex the dentry must exist for the mount to have
      completed so the test is not really needed.
      
      Mounts can also be done on top of a global root dentry, so for the above
      case, where a mount request completes and the wait queue entry has already
      been removed, the hashed test returning false can cause an incorrect
      callback to the daemon.  Also, d_mountpoint() is not sufficient to check
      if a mount has completed for the multi-mount case when we don't have a
      real mount at the base of the tree.

      it turns out that we need clear cpus_hardware_enabled in that case.

      These are defined as static cpumask_var_t so if MAXSMP is not used,
      they are cleared already.  Avoid surprises when MAXSMP is enabled.

      cls_cgroup: Fix oops when user send improperly 'tc filter add' request · 52ea3a56
      Minoru Usui authored
      I found a bug in cls_cgroup_change() in cls_cgroup.c.
      cls_cgroup_change() expected tca[TCA_OPTIONS] was set from user space properly,
      but tc in iproute2-2.6.29-1 (which I used) didn't set it.
      
      In the current source code of tc in git, it set tca[TCA_OPTIONS].
      
        git://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git
      
      
      
      If we always use a newest iproute2 in git when we use cls_cgroup, 
      we don't face this oops probably.
      But I think, kernel shouldn't panic regardless of use program's behaviour.

      r8169: fix crash when large packets are received · fdd7b4c3
      Eric Dumazet authored
      Michael Tokarev reported receiving a large packet could crash
      a machine with RTL8169 NIC.
      ( original thread at http://lkml.org/lkml/2009/6/8/192
      
       )
      
      Problem is this driver tells that NIC frames up to 16383 bytes
      can be received but provides skb to rx ring allocated with
      smaller sizes (1536 bytes in case standard 1500 bytes MTU is used)
      
      When a frame larger than what was allocated by driver is received,
      dma transfert can occurs past the end of buffer and corrupt
      kernel memory.
      
      Fix is to tell to NIC what is the maximum size a frame can be.
      
      This bug is very old, (before git introduction, linux-2.6.10), and 
      should be backported to stable versions.
