      [PATCH] Fix IDE bus reset and DMA disable when reading blank DVD-R · 314dc154
      Jens Axboe authored
      From Jon Burgess:
      
        There is a problems with blank DVD media using the ide-cd driver.
      
        When we attempt to read the blank disk, the drive responds to the read
        request by returning a "blank media" error.  The kernel doesn't have
        any special case handling for this sense value and retries the request
        a couple of times, then gives up and does a bus reset and disables DMA
        to the device.
      
        Which obviously doesn't help the situation.
      
        The sense key value of 8 isn't listed in ide-cd.h, but it is listed in
        scsi.h as a "BLANK_CHECK" error.
      
        This trivial patch treats this error condition as a reason to abort
        the request.  This behaviour is the same as what we do with a blank CD-R.
      
        It looks like the same fix might be desired for 2.4 as well, although
        is perhaps not so important since scsi-ide is normally used instead.

      [PATCH] Fix possible bio corruption with RAID5 · e1f936a9
      Neil Brown authored
       1/ make sure raid5 doesn't try to handle multiple overlaping
          requests at the same time as this would confuse things badly.
          Currently it justs BUGs if this is attempted.
       2/ Fix a possible data-loss-on-write problem.  If two or
          more bio's that write to the same page are processed at the
          same time, only the first was actually commited to storage.
       3/ Fix a use-after-free bug.  raid5 keeps the bio's it is given
          in linked lists when more than one bio touch a single page.
          In some cases the tail of this list can be freed, and
          the current test for 'are we at the end' isn't reliable.
          This patch strengths the test to make it reliable.

      Fix thread group leader zombie leak · 056ffaad
      Linus Torvalds authored
      Petr Vandrovec noticed a problem where the thread group leader
      would not be properly reaped if the parent of the thread group
      was ignoring SIGCHLD, and the thread group leader had exited
      before the last sub-thread.
      
      Fixed by Ingo Molnar.

      More subtle SMP bugs in prepare_to_wait()/finish_wait(). · e220fdf7
      Linus Torvalds authored
      This time we have a SMP memory ordering issue in prepare_to_wait(),
      where we really need to make sure that subsequent tests for the
      event we are waiting for can not migrate up to before the wait
      queue has been set up.

      [PATCH] HPFS: missing lock_kernel() in hpfs_readdir() · 14c5d2d2
      René Scharfe authored
      In 2.5.x, the BKL was pushed from vfs_readdir() into the filesystem
      specific functions.  But only the unlock_kernel() made it into the HPFS
      code, lock_kernel() got lost on the way.  This rendered the filesystem
      unusable.
      
      This adds the missing lock_kernel().  It's been tested by Timo Maier who
      also reported the problem earlier today.

      [PATCH] no bio unmap on cdb copy failure · 5965168e
      Jens Axboe authored
      The previous scsi_ioctl.c patch didn't cleanup the buffer/bio in the
      error case. 
      
      Fix it by copying the command data earlier.

      This patch was integrated by you in 2.4 six months ago.  Unfortunately
      it never got into 2.5.  Without it you can end up with crashes such

      [PATCH] USB: fix race with signal delivery in usbfs · 41b98670
      Oliver Neukum authored
      apart from locking bugs, there are other races. This fixes one with
      signal delivery. The signal should be delivered _before_ the reciever
      is woken.

      After a bit of mucking around (and possibly finding a bug with debian's
      libusb/xsane/hotplug interaction, nothing seems to run
      /etc/hotplug/usb/libusbscanner and thus only root can scan, anyone whose

      only use  libusb xsane.
      
      How about the following:

      [PATCH] scsi_ioctl memcpy'ing user address · 8cc86c08
      Jens Axboe authored
      James reported a bug in scsi_ioctl.c where it mem copies a user pointer
      instead of using copy_from_user(). I inadvertently introduced this one
      when getting rid of CDROM_SEND_PACKET. Here's a trivial patch to fix it.

      [PATCH] Fix 'noexec' behaviour · 58392dbd
      Ulrich Drepper authored
      We should not allow mmap() with PROT_EXEC on mounts marked "noexec",
      since otherwise there is no way for user-supplied executable loaders
      (like ld.so and emulator environments) to properly honour the
      "noexec"ness of the target.

      Jean Delvare authored
      This patch fixes i2c_smbus_write_byte() being broken for i2c-nforce2.
      This causes trouble when that module is used together with eeprom (which
      is also in 2.6). We have had three user reports about the problem.
      
      Credits go to Mark D. Studebaker for finding and fixing the problem.
