      [PATCH] SELinux leak fixes · 07c9e4a4
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      I believe that the patch below fixes the legitimate leaks in the SELinux
      code.  In some cases, it rearranges the code (moving the allocation later
      to reduce the need for further cleanup or linking the object into a
      containing structure earlier so that the policydb_destroy will handle it
      upon any subsequent errors).

      [PATCH] asm/softirq.h is dead · b5ec6dea
      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      Still three arches keep an unused copy around and quite a few places refer
      to it in comments still.
      
      Two of the two arches also include it in their _ksyms.c file, but given
      that softirq.h only contains macros (which are in hardirq.c as well) that's
      just a leftover as well.

      [PATCH] use "normalized" syntax for lgdt/lidt · a84d3317

      Use common (normalized) asm syntax for lidt/lgdt, specifying that the
      operand is an input value instead of output.

      [PATCH] DAC960: remove redundant (and uninitialized) · b7f6576c
      Andrew Morton authored
      From: Dave Olien <dmo@osdl.org>
      
      this patch fixes a bug that appeared only on Alpha hardware with
      DAC960 controllers.  The Command->PciDevice structure member was
      never initialized.  This was passed to the pci scatter/gather functions.
      This didn't cause a problem for x86 platforms because the scatter/gather
      funtions never really used that information.  Alpha platforms do use
      that pointer.
      
      The Command->PciDevice field was also redundant with the Controller->PCIDevice
      field, which IS initialized properly.  So, eliminating the redundant
      structure member and substituting the Controller's member fixes the bug.

      Yes. Here 2.4 had the terrible code
      
           mode = (inode->i_mode & S_IXGRP)*(S_ISGID/S_IXGRP) | S_ISUID;
      
      while 2.6 does things via notify_change().  However, in 2.6 notify_change()
      does not allow removal of the SUID bit because you are not owner of the
      file :-).  So, we have to convince inode_change_ok() to do it anyway.

      [PATCH] make CONFIG_HUGETLB_PAGE mirror CONFIG_HUGETLBFS · 829d1232
      Andrew Morton authored
      At present you can set CONFIG_HUGETLB_PAGE and not CONFIG_HUGETLBFS, which
      give the kernel low-level hugepage support, but no userspace API with which
      to access it.
      
      And with the recent hugetlbfs-accounting fix, the low-level code needs
      functions which are in hugetlbfs, so CONFIG_HUGETLBFS=n,
      CONFIG_HUGETLB_PAGE=y doesn't even link.
      
      So we flip things around: CONFIG_HUGETLB_PAGE is set if CONFIG_HUGETLBFS is
      set and CONFIG_HUGETLB_PAGE is unset if CONFIG_HUGETLBFS is unset.  The
      CONFIG_HUGETLB_PAGE option hence disappears from the per-arch configuration
      menus.

      [PATCH] Hugetlb FS quota accounting problem · 41cffedc
      Andrew Morton authored
      From: "Chen, Kenneth W" <kenneth.w.chen@intel.com>
      
      We found a problem in hugetlbfs file system quota when using huge page
      via mmap.  The mmap method in hugetlbfs_file_operation always takes
      quota for every mmap even for pages that are already allocated on that
      inode.  This results in taxing the same hugepage multiple times and
      causing mmap to fail on existing file when quota mistakenly runs out.

      All drivers that compile on ppc with CONFIG_ISA set (= all but
      some m68-only drivers), I looked at the compile warnings very
      closely and there are no new warnings or even errors this time :)

      the intialization order the same.

      [PATCH] disallow utime{s}() on immutable or append-only files · 905f90fe
      Andrew Morton authored
      From: Ethan Benson <erbenson@alaska.net>
      
      Currently Linux allows the use of the utime() and utimes() syscalls on
      immutable or append-only files, this is incorrect.
      
      utime{s}() is not supposed to work if you lack write access to a file,
      in the case of an immutable file NOBODY has write access.
      
      for an append-only file it only makes sense to be able to update its
      time to present, not the past.
      
      I have checked BSD, and they implement the behavior I propose, for
      immutable files utime() and utimes() fail.  for append-only files they
      fail if the time argument is not NULL.

      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      Richard hasn't touched it for about a year and since then only bugfixes and
      my changes to the kernel interface went in.  No one has stepped up to
      maintain it and with udev we have a proper replacement now.
      
      I will do some more work before 2.6 (mainly trying to implement Al's
      refcounting scheme to avoid stale entries), but that's it.

      [PATCH] Try harder in IRQ context before falling back to ksoftirqd · e4e9bd23
      Andrew Morton authored
      From: "David S. Miller" <davem@redhat.com>
      
      It's from Ingo Molnar.  ksoftirqd kicks in way too early, so do more work in
      interrupt context before falling back.
      
      We can probably sysctl this thing, that way everyone gets what they want
      probably...
      
      (has been in -mm since 2.5.71 and I haven't heard a peep).

      [PATCH] 32-bit dev_t: switch-over · 1c2c2a8f
      Alexander Viro authored
      Real conversion to 32bit dev_t.  Expansion to:
      	* mknod() - 32
      	* newstat() - 32 on 64bit platforms
      	* stat64() - 32 on mips, 64 on everything else (mips has weird struct
      stat64 and can't get more than 32 bits).  Note that right now the difference
      is purely theoretical - we don't have internal values above 32 bits, so
      huge_... vs. new_... only marks the places where 64bit conversion will need
      extra work.
      	* arch-dependent stat variants - depending on width available.
      	* ustat et.al. - 32
      	* filesystems that can handle 32 bits right now - 32
      	* ext2 and ext3 - 32, with large dev_t inodes having 0 in the first
      element of i_data[] (where we store dev_t value for small device numbers) and
      keeping the value in the second element.
      	* nfsd - 32; it can be driven to 64, but we'll get several issues with
      NFSv2 support.
      	* RAID - 32
      	* devmapper - with v1 it's still 16 (nothing to do here), with v4 it's
      64.
      	* loop - 64
      	* initramfs - 32
      	* do_mounts code - 32.  Parts that scan devfs tree are using newstat()
      on 64bit platforms and stat64() on the rest (IOW, the latest stat variant on
      given platform).
      	* old_valid_dev()/new_valid_dev() added where needed (stat variants,
      mostly - we fail with -EOVERFLOW if values do not fit).

      [PATCH] 32-bit dev_t: internal use · 40d2adc6
      Alexander Viro authored
      Starting the conversion:
      	* internal dev_t made 32bit.
      	* new helpers - new_encode_dev(), new_decode_dev(), huge_encode_dev(),
      huge_decode_dev(), new_valid_dev().  They do encoding/decoding of 32bit and
      64bit values; for now huge_... are aliases for new_... and new_valid_dev()
      is always true.  We do 12:20 for 32bit; representation is compatible with
      16bit one - we have major in bits 19--8 and minor in 31--20,7--0.  That's
      what the userland sees; internally we have (major << 20)|minor, of course.
      	* MKDEV(), MAJOR() and MINOR() updated.
      	* several places used to handle Missed'em'V dev_t (14:18 split)
      manually; that stuff had been taken into common helpers.
      	Now we can start replacing old_... with new_... and huge_..., depending
      on the width available.  MKDEV() callers should (for now) make sure that major
      and minor are within 12:20.  That's what the next chunk will do.

      	Now we are free to change dev_t in any way we want - on all boundaries
      we have explicit conversions.
      	Took __kernel_dev_t definition to linux/types.h and changed it with
      __u16.  We are ready to proceed to 32bit now.

      ->s_dev of exported fs doesn't fit into 256:256; in that case we put major
