      [PATCH] s390: common i/o layer · 53e7ea7f
      Andrew Morton authored
      From: Martin Schwidefsky <schwidefsky@de.ibm.com>
      
       - Make blacklist busid-aware. Add "all" keyword and ! operator to cio_ignore
         kernel parameter.
       - Add state change notify function for ccw devices (not mandatory) and
         introduce the "device disconnected" state.
       - Remove auto offline from remove function for ccw devices to be able to
         distinguish between user initiated offline and implicit offline due to
         device removal.
       - Store pointer to subchannel structure in the (hardware) subchannel intparm
         and remove the ioinfo array (hurray...). Remove intparm parameter of
         cio_start.
       - Use busid instead of subchannel number for debug output.
       - Use an opm mask to track which paths are logically online for a subchannel.
       - Pathgroup every device it was requested for, even single path devices.
       - Give i/o on a logically switched off path a grace period to complete, then
         kill the i/o to get the path offline.
       - Correctly initialize all spin_locks with spin_lock_init.
       - Handle status pending/busy while disabling subchannel.
       - Set busid already in cio_validate_subchannel.
       - Add s390_root_dev_{register,unregister} functions.
       - Do stcrw() inside a kernel thread. Add crw overflow handling.
       - Use subchannel lock directly instead of ccw device lock pointer in
         ccw_device_recognition to avoid accessing an already free structure.
       - Take/release ccw device lock in ccw_device_console_enable.
       - Don't wipe out the busid field in ccw_device_console_enable.
       - Call ccw_device_unregister() directly on a notoper event - delaying it via
         queue_work is harmful (subchannel may be removed before ccw_device).
       - Handle not opertional condition in ccw_device_cancel_halt_clear.
       - Correct status pending handling: don't collect pending status directly
         but wait for the interrupt to show up.
       - Enable subchannel when trying a steal lock operation.
       - Introduce doverify bit for delayed path verification.
       - Fix locking in __ccw_device_retry_loop/read_conf_data/read_dev/chars.
       - Make SPID retry mechanism more obvious.
       - qdio: check return code of ccw_device_{halt,clear} in qdio_cleanup. Don't
         try to wait for an interrupt we won't get.
       - qdio: fix shared indicators.
       - qdio: add code to handle i/o killed by cio with active queues.
       - qdio: don't do a shutdown on timeout in interrupt context.
       - Update cio documentation.

       - Add panic_on_oops.
       - Display symbol for psw address in show_trace.
       - Don't discard sections .exit.text, .exit.data and .eh_frame,

       - Add memory clobber to assembler inline in ip_fast_checksum for gcc 3.3.
       - Fix softirq_pending calls for the current cpu (cpu == smp_processor_id()).

      [PATCH] nfs: Fix an open intent bug · 7de3a7b2
      Andrew Morton authored
      From: Trond Myklebust <trond.myklebust@fys.uio.no>
      
      The following patch fixes a bug when initializing the intent structure
      in sys_uselib(): intents use the FMODE_READ convention rather than
      O_RDONLY.
      
      It also adds a missing open intent to open_exec(). This ensures that NFS
      clients will do the necessary close-to-open data cache consistency
      checking.

      [PATCH] nfs: Optimize away unnecessary NFSv3 COMMIT calls. · ac48c0dd
      Andrew Morton authored
      Currently, when calling nfs_commit_file(), we check the range argument,
      and only commit NFS write requests that fall within the given range.
      This is silly, since all servers use fsync(), to honour a COMMIT call,
      and so will sync all pending writes to stable storage.
      
      The following patch ensures that if at least one NFS write falls within
      the range specified by the call to nfs_commit_file(), then we commit all
      outstanding writes on that file.
      
      This fixes a sometimes severe inefficiency when combining reads and
      writes: nfs_wb_page() is used to clear out writes prior to scheduling a
      read(), and can end up calling COMMIT for each page to be read.

      [PATCH] NFS: fix bogus setattr calls · 2f4c9a2d
      Andrew Morton authored
      From: Trond Myklebust <trond.myklebust@fys.uio.no>
      
      If users set the execute bit on a file, and then write to it,
      remove_suid() causes a flood of SETATTR calls (one per write() syscall)
      with no arguments to be sent down the wire.
      
      The server will in any case clear the suid bit itself without any
      prompting from us, so the following patch simply filters away all
      SETATTR requests with empty or unsupported ia_valid fields.

      [PATCH] selinux: improve skb audit logging · e0e9c58e
      Andrew Morton authored
      From: James Morris <jmorris@redhat.com>
      
      This patch is a rework of the skb audit logging code in SELinux.  Rather
      than relying on skb header pointers, it parses the skb for specific
      protocols (TCP and UDP for IPv4 at this stage).  This is safer for the case
      of locally generated raw packets, which can be malformed.  It also now
      takes fragmented skbs into account.  The new code allows the caller to
      parse the skb so that parsed information can be more readily re-used.

      [PATCH] selinux: Add SO_PEERSEC socket option and getpeersec LSM hook. · da6e57a2
      Andrew Morton authored
      From: James Morris <jmorris@redhat.com>
      
      This patch adds a new option for Unix sockets, SO_PEERSEC, and an
      associated LSM hook, getpeersec.  The SELinux handler is also included.
      
      The purpose of this is to allow applications to obtain each others security
      credentials, analagously to the existing SO_PEERCRED option.
      
      Examples of use are Security Enhanced D-BUS and Security Enhanced X.
      
      This patch was previously approved in principle by David, and has been
      updated with feedback from Chris Wright and extended to cover all
      architectures.

      From: James Morris <jmorris@redhat.com>
      
      This patch adds 'node' access controls for SELinux, which allows network

      Like the previous patch, similar functionality was present in earlier

      From: James Morris <jmorris@redhat.com>
      
      This patch adds controls to the SELinux module over the setting and
      inheritance of resource limits.  With these controls, the ability to set
      hard limits can be limited to specific processes such as login, and when an
      untrusted process invokes a more trusted program, soft limits can be reset,
      thereby avoiding failures in the trusted program due to malicious setting
      of the soft limit by the untrusted process.  Roland McGrath provided input
      and feedback on the patch, which was implemented by Stephen Smalley

      Yet another sound/oss/trident cleanup patch.  This one replace the TRDBG
      debugging macro with the standard pr_debug.  Patch is from Eugene Teo
      <eugene.teo@eugeneteo.net>, slightly modified by me to apply against
      2.6.0-rc1-mm1 with the other cleanup patches applied.

      [PATCH] trident OSS sound driver fixes · 0d7bcc30
      Andrew Morton authored
      From: Muli Ben-Yehuda <mulix@mulix.org>
      
      - switch lock_set_fmt() and unlock_set_fmt() from macros to inline
        functions.  Macros that call return() are EVIL.
      
      - simplify lock_set_fmt() and implement it via test_and_set_bit() rather
        than a spinlock protecting an int.
      
      - fix a bug wherein we would do an up() on a semaphore that hasn't been
        down()ed if a signal happened after timeout in trident_write().
      
      - fix a bug where we would not release the open_sem on OOM.
      
      - make the arguments for prog_dmabuf clearer (int -> enum), and add two
        wrapper functions around it, one for record and one for playback.  
      
      - fix a bug where we would call VALIDATE_STATE after lock_kernel().  Since
        VALIDATE_STATE does 'return' if validation fails, bad things can happen. 
        Thanks to Dawson Engler <engler@stanford.edu> and the Stanford checker for
        spotting.
      
      - remove the calls to lock_kernel() from trident_release() and
        trident_mmap().  trident_release() appears to be covered by the open_sem,
        and trident_mmap() is covered by state->sem.

      Now that modutils don't have built-in aliases anymore this is needed to
      make mount -t vxfs autload the module.

      [PATCH] generalise net_ratelimit (printk_ratelimit) · 11a61205
      Andrew Morton authored
      From: Anton Blanchard <anton@samba.org>
      
      Generate a global printk rate-limiting function, printk_ratelimit().
      
      Also, use it in the page allocator warning code.  Also add a dump_stack to
      that code.
      
      Later, we need to switch net_ratelimit() over to use printk_ratelimit().

      Buddha/CatWeasel IDE: Make sure the core IDE driver doesn't try to request the
      MMIO ports a second time, since this will fail.
