      [PATCH] selinux: check return value for receive node permission · 735c736e
      Andrew Morton authored
      From: James Morris <jmorris@redhat.com>
      
      This patch fixes a bug where the return value for a permission call is not 
      checked.
      
      The bug was introduced when I added some code in the following changeset:
      
      <http://linux.bkbits.net:8080/linux-2.5/diffs/security/selinux/hooks.c@1.19?nav=index.html|src/|src/security|src/security/selinux|hist/security/selinux/hooks.c>
      
      Code was added after this line:
      
      	err = avc_has_perm(isec->sid, node_sid, SECCLASS_NODE, node_perm, NULL, &ad);
      
      without adding an explicit check of 'err', which was previously returned
      from the function rather than being checked.  i.e. it would drop through
      to:
      
      	out:	
       		return err;
      
       	}
      
      With the new code added, err can (and typically would) be overwritten with 
      a successful value, causing the permission check to not deny permission if 
      needed.  The intended denial would have been logged.
      
      The patch below fixes this problem.

      [PATCH] adjuct cpu_khz in response to cpufreq changes · e9c7ac4a
      Andrew Morton authored
      From: john stultz <johnstul@us.ibm.com>
      
      This patch ensures that cpu_khz is adjusted on cpufreq notifications even
      when the tsc timesource is not in use.  It fixes the mostly cosmetic issue
      when using the ACPI PM timesource of /proc/cpuinfo not being properly
      updated when cpu frequency was lowered.

      [PATCH] s390: system call speedup part 1. · 42aef4b0
      Andrew Morton authored
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
      The purpose of this is to speed up system calls on s390.  I managed to
      squeeze about 65 cycles from each system call.  This improved e.g.  getpid()
      from 232 to 157 cycles.  As a nice side-effect it simplified the uaccess
      functions considerably.

      Andrew Morton authored
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
      s390 network driver changes:
       - ctc/lcs/qeth: prevent a ccw-device to be grouped multiple times.
       - icuv: clear correct field in iucv_register_program if no userid is specified.
       - lcs: fix online/offline cycle again.
       - lcs: fix ungrouping of lcs group device. The channels of the lcs card
         should be offline afterwards.
       - lcs: don't do netif_stop_queue if no tx buffer is available, just
         return -EBUSY and drop the packets.

      [PATCH] s390: dasd driver. · 8fea2343
      Andrew Morton authored
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
      dasd device driver changes:
       - After a state change interrupt restart all running i/o on queue
         and reset device timer.
       - Improve some debug messages.
       - Lower timeout of reserve/release/steal_lock to 2 seconds.
       - Fix BIODASDPSRD ioctl.
       - Replace ro_flag, use_diag_flag and disconnect_error_flag words by bits.
       - Use BLKPG_DEL_PARTITION ioctl instead of a call to delete_partition because
         delete_partition is not an exported function. Since dasd_destroy_partitions
         can't do blkdev_get because dasd_open would fail, keep the block device
         open as long as partitions exist. This in turn requires a different
         approach to the open vs. offline race.

      [PATCH] Fix cyclades async driver timeout miscalculation · fbd033be
      Marcelo Tosatti authored
      This fixes a problem where cy_wait_until_sent() miscalculates (calculate
      -1 on a unsigned long) the "char_time" parameter passed to
      schedule_timeout().
      
      Fix that by making it a signed long, and checking for negative value.

      [PATCH] Emulate deviceless bridge ioctls · 44fbe3d2
      Andi Kleen authored
      This helps vmware users running vmware on x86-64 - vmnet tries to set up a bridge.
      Emulate these ioctls. The bridge has more ioctls on its bridge device, but these
      don't seem to be needed here.

      [PATCH] ppc32: arch code preempt fixes · 62e160b5
      Benjamin Herrenschmidt authored
      I figured the best way to stop beeing bothered by users trying to run
      preempt was to fix it ;)
      
      Here's a first batch that close some races we had when testing regs->msr
      for altivec or FPU enable, then doing the giveup_* function.  A preempt
      in between those would have caused us to save a stale altivec or FPU
      context.

      [PATCH] dmasound close timeout · 01472f19
      Benjamin Herrenschmidt authored
      The dmasound driver occasionally hangs a process on exit.
      
      Apparently there is a possible case where the sound HW stops draining
      output samples and the driver waits forever in its release() callback.
      It should check for signals(), but it seems signal_pending() never
      returns 1 when the process is beeing killed (implicit release() of files
      on exit).
      
      This patch adds a safety timeout to the release() function to make sure
      we can at least close the driver.  I'll try to find the reason we aren't
      driving samples later, but it is better to have a safety just incase the
      sound clock goes berserk for some reason.

      [PATCH] ppc32: Fix racy access to TI_FLAGS · 1c754472
      Benjamin Herrenschmidt authored
      The ppc32 syscall entry code could access the thread info flags in a
      racy way, thus potentially losing bits sets there at interrupt time or
      by another CPU, like NEED_RESCHED or SIGPENDING (ouch !).
      
      This fixes it by moving the potentially racy bit to a different field (I
      preferred that rather than turning the access into an atomic operation
      for performances reasons).

      [ARM] Remove Anakin machine support. · 02cae55d
      Russell King authored
      Anakin has not been maintained since it was (partially) merged, and
      the maintainers appear to ignore mail about it.  No one appears
      willing to maintain it either.  However, some unrelated kernel
      maintainers have been updating various files while they've been
      working in the area - which is wasted work for something which
      isn't maintained.
      
      Therefore, this cset removes Anakin completely from the kernel.
