      [PATCH] knfsd: Add 'threads' file to nfsd filesystem to allow changing number of threads. · bb1eb94c
      Neil Brown authored
      This uses the read-without-write style transaction files in nfsctl.
      We can write a number of threads, and then read back the number of
      threads that resulted, or we can just open and read in which case
      we read back the number of threads without changing it.

      [PATCH] knfsd: Add 'filehandle' entry for nfsd filesystem for looking up a filehandle · 9838159a
      Neil Brown authored
      The getfh system call takes an IP address, which is only
      really appropriate for AUTH_UNIX authentication.
      
      With this interface, you call can ask for a filehandle for a
      particular domain.
      
      You write
       domainname pathname maxlength
      to the file, and then read back the filehandle
      
      All strings a qword quoted.

      [PATCH] knfsd: Change names of legacy interfaces in nfsd filesys to start with period · e7f81aa3
      Neil Brown authored
      The nfsd filesystem provides an interface to nfsd.
      Most of the current files should be considered legacy
      interfaces as they are not particularly suitable for
      filesystem interaction, but are required to support the
      syscall interface.
      This patch puts a '.' in front of all the names so they
      appear as hidden names when the directory is listed.

      [PATCH] knfsd: Fixes for nfsd filesystem files · 71713ecd
      Neil Brown authored
      The transaction files in the 'nfsd' filesystem
      stores the per-transaction response size in the per-inode
      i_size, which is wrong.
      With this patch a page is allocated for holding size and
      request and response, so routines don't need to
      copy_fromuser.
      
      Also, some routines were allocating rather large (>1024 bytes)
      stuctures on the stack for copy_fromuser into, which was not
      nice and is now not needed.
      
      Also, writeonly and write_read methods are unified in a single
      transaction style interface.
      Write then read performs and action and returns a response.
      Write without read just performs the action and ignores response.
      Read without write triggers an empty transaction which can still have
      a response.  That functionality will be used in a later patch.

      [PATCH] knfsd: Provide 'flush' interface for userspace to flush rpc/svc caches · 50d3bcac
      Neil Brown authored
      Userspace can with a time (seconds since epoch) to
        /proc/net/rpc/*/epoch
      and all entries created earlier than that time will be flushed.

      [PATCH] knfsd: Allow rpcsvc caches to provide a 'cache_show' method · 007f7383
      Neil Brown authored
      This provides a /proc/sunrpc/*/content seq_file for caches to display
      their content.
      
      This code is based on the code for /proc/fs/nfs/exports

      to use cache_check instead of checking the various state
      bits manually.

      [PATCH] knfsd: Don't assume a reader on an RPC cache channel at statup. · b1321130
      Neil Brown authored
      Each cache channel remembers if there was a reader recently.
      If there wasn't, then it doesn't bother with an up-call.
      Currently, it initialises thinking there was a reader
      recently incase the reader starts shortly afterwards.  However
      this causes problems when a reader doesn't start soon, and
      isn't necessary as the reader can easily be started before
      the cache is initialised (e.g. before nfsd is started).

      [PATCH] Introduce TIF_IRET and use it to disable sysexit · b10bf295
      Luca Barbieri authored
      This patch introduces a new flag called TIF_IRET and uses it in place
      of TIF_SIGPENDING when that flag is used to force return via iret.
      
      This avoids the overhead of calling do_signal and makes the code
      easier to understand.

      [PATCH] Fix sysenter (%ebp) fault handling · a7df6f33
      Luca Barbieri authored
      Currently syscall_badsys is called to handle faults when reading the
      sixth parameter in sysenter; however that routine assumes that
      registers have already been pushed on the stack, and this is not the
      case (in other words, it will currently try to pop beyond the end of
      the thread stack).
      
      This patch adds a new "function", syscall_fault, that saves register
      and returns.
      
      The return value is changed to EFAULT, which seems more appropriate
      than ENOSYS.

      [PATCH] 2.5.54 AGP driver fixes for x86-64 · b45aba16
      Andi Kleen authored
      This is just to make x86-64 boot with IOMMU and compiled in AGP driver
      again.  Previously both AGP and the IOMMU code would set up an aperture,
      with AGP being winner, messing up pci_map_*.
      
      This is needed for the x86-64 update for 2.5.54 I sent earlier.
      
      Actually using /dev/agpgart still corrupts memory unfortunately, haven't
      tracked that down yet.
      
      I also commented on some (usually 64bit, but at least one 32bit) bugs in
      the driver too.
      
      These changes should be all nops on i386.
      
       - Export amd k8 init function for x86-64.  It needs to be called early
         by the iommu code.  Add some comments to warn about about that (the
         upcoming VIA and SIS K8 chipsets will have the same problem)
       - Declare gatt table as u32 following the AGP spec.
       - Comment some bugs.

      [PATCH] x86-64 updates for 2.5.54 · 717db2f9
      Andi Kleen authored
      More x86-64 updates for 2.5.54.  Most noticeable change is that the
      64bit X server works again.
      
      This only changes x86-64 specific files.  It requires some AGP driver
      changes I'm sending separately.
      
       - Some Makefile cleanups from Sam Ravnborg
       - Make sure extended registers in 32bit processes are zeroed and not
         accessible/changeable from ptrace.  This is to avoid potential
         security bugs with non 64bit clean 32bit emulation functions (they
         often are overflow prone etc.)
       - Some 32bit emulation cleanups from Stephen Rothwell
       - Make copy_*_user source const to fix warnings.
       - Set fs/gs to dummy values when the 64bit segment base is set to not
         confuse the context switch (Karsten Keil, me)
      	* still one mysterious bug in this area unfortunately.
       - Make MAP_32BIT for 64bit processes only map in the first 31bit,
         because it is usually used to map small model code.  This fixes the X
         server crashes.  Some cleanups in this area.
       - Don't set O_LARGEFILE for 32bit open
       - Handle ptregs calls from 32bit syscall correctly.
       - Implement aio io_getevents for 32bit.
       - Remove buggy unused command handler in nfsd 32bit emulation.
       - Convert timespec in semtimedop (thanks to Anton for telling me about
         this)
       - Ignore long mode flag from 32bit modify_ldt.  This fixes Wine, which
         left it uninitialized (bug found by Karsten Keil)
       - Merge with i386
       - Handle new kallsyms
       - Remove some superfluous bootup printks

      [PATCH] scsi_scan.c · 3cf172fe
      Andries E. Brouwer authored
      Wondering why my CD-writer did not have a name in sysfs, I saw
      that when the name is longer than 50 bytes no name at all is used.
      The (much smaller) code below constructs a truncated name instead.
