      [PATCH] remove io context refcounting debug · d302b497
      Nick Piggin authored
      This removes the remains of some debugging stuff which was never really
      enabled properly - it never reported memory leaks.  Its not useful for
      anyone but me. 
      
      A proper solution involves counting all requests in flight and all
      threads but we'll probably put that just into mm.

      [PATCH] Improve sget() performance · d549b9ab
      Alexander Viro authored
      sget() is pessimistic and assumes it won't find a superblock - and as a
      result it always pre-allocates a new one before even searching for an
      existing entry.  If it finds an existing one, it free's the extra one it
      just allocated.
      
      Especially with /proc usage it usually _does_ find an existing
      superblock, so this is all extra work.  It should allocate a new one
      only if it couldn't find an old one (and re-search).
      
      The same way as iget() does it.

      [PATCH] Better UDF oops fix · 7db66084
      Alexander Viro authored
      Rather than not kfree'ing the UDF data in the case of a bad inode (which
      still _may_ have had the UDF data already allocated to it), make sure to
      initialize the pointer to NULL properly when we're done with it.

      [PATCH] /proc/PID/auxv file and NT_AUXV core note · 2e54af56
      Andrew Morton authored
      From: Roland McGrath <roland@redhat.com>
      
      gdb really needs some way to know the AT_SYSINFO_EHDR value for a process
      being debugged or for the dead process described by a core file.  Without
      this value, it can't find the information necessary to show backtraces of
      threads waiting in system calls.  There are any number of ways this
      information could be made available.  Here is one solution that provides
      more debugging information in a clean and general fashion.
      
      I've added access to the AT_* values passed to a process for third parties
      to examine for debugging purposes.  The same data passed on the stack at
      startup is made available in /proc/PID/auxv and is written in an NT_AUXV
      note in core dumps.  (Both of these are consistent with what Solaris does
      using the same names.)
      
      Here are two different patches that implement the same thing differently.
      The first patch uses a ref-counted data structure to copy the aux vector
      and shares among forked mm's until they exec and get a new one.  The second
      patch avoids the complexity of that data structure by simply expanding the
      mm_struct with space to hold a copy of the data.  Both patches work
      correctly; I have examined the new /proc/PID/auxv file and core dumps.
      
      I hope you will consider including one of these patches, or at least some
      way of getting at this information from the debugger.  I am certainly open
      to other suggestions on implementing this feature, and to suggestions on
      alternative interfaces for getting the AT_SYSINFO_EHDR value cleanly.

      this patch makes some ints to unsigned ints.  They are only used as loop
      counters and compared to unsigned ints.  GCC 3.3 doesn't like this.  They
      will never be negative anyway, so we could easily shut him up.

      [PATCH] Pass nameidata to security_inode_permission hook · d5f1f9dd
      Andrew Morton authored
      From: Stephen Smalley <sds@epoch.ncsc.mil>
      
      This patch changes the security_inode_permission hook to also take a
      nameidata parameter in addition to the existing inode and mask parameters. 
      
      A nameidata is already passed (although sometimes NULL) to
      fs/namei.c:permission(), and the patch changes exec_permission_lite() to
      also take a nameidata parameter so that it can pass it along to the
      security hook.
      
      The patch includes corresponding changes to the SELinux module to use the
      nameidata information when it is available; this allows SELinux to include
      pathname information in audit messages when a nameidata structure was
      supplied.

      [PATCH] check permission in ->open for /proc/sys/ · dc5f46be
      Andrew Morton authored
      From: Christoph Hellwig <hch@lst.de>
      
      It's the only abuse of proc_iops left (except the totally b0rked comx
      driver).  The patch is from Al, I just forward-ported it from 2.4.
      
      Background: struct proc_dir_entry has a struct inode_operations *proc_iops
      member, it's from Linux's stoneage and used internally by procfs to assign
      either the link or directory inode ops.
      
      Unfortunately some drivers started to abuse it do do bad things like create
      on lookup (that's the comx thingy which relies on unexported symbols and thus
      is broken for modular builds since mid-2.3) or various ->permission tricks
      (all gone by now).
      
      After this patch is gone I have another one that kills proc_iops and just
      uses a normal conditional inside procfs to assign the right one directly.

      Found this while converting netfilter modules to use the new
      parameters.  Also fixes an out-by-one error in maximum elements you
      can put in array.
      
      The current "intarray" module params were never tested, and um, suck.
      Only one person uses them, and it looks painful.
      
      Since noone uses them, replace them with tested versions.

      [PATCH] memory writeback/invalidation fixes · b2dd8674
      Andrew Morton authored
      From: "David S. Miller" <davem@redhat.com>
      
      This attempts to take care of 2 of the MM todos I had on
      my backlog:
      
      1) Zap the stupid flush_cache_all() thing with more meaningful
         interfaces.
      
      2) Resolve the ptrace user page access issues, first stage.
      
      The "first stage" mentioned for #2 is simply creating the
      user page accesor interfaces.  The next stage needs to be
      mucking with get_user_pages() so that we can control when
      the flush_dcache_page() occurs.  Then we:
      
      1) For every platform where flush_dcache_page() is a non-nop
         add a call to the beginning of copy_{from,to}_user_page().
      2) Make access_process_vm() set the "no dcache flush" bit in
         it's call to get_user_pages().
      
      The idea also was that we'd consolidate the write etc. boolean
      args passed to get_user_pages() into flag bits too.
      
      But at least with the below, we can delete that reminder FIXME
      comment from kernel/ptrace.c, the platforms have the necessary
      tools and just need to make use of it :)
      
      As a bonus I noticed that VMALLOC_VMADDR() did absolutely nothing.
      
      After all of this I only have 1 real TODO left, and that's dealing
      with the SMP TLB/pte invalidation stuff, very low priority until
      someone starts doing more work with sparc32/SMP in 2.6.x :)

      [PATCH] dev_t forward compatibility fix · 1885b3f1
      Andrew Morton authored
      From: Andries.Brouwer@cwi.nl
      
      ext2 used a 32-bit field for dev_t, with possibly undefined storage
      following; thus, no action was required to go to 32-bit dev_t, but going to
      64-bit dev_t required some subtlety: 0 was written in the first word and
      the 64 bits in the following two.  Al truncated my 64-bit stuff to 32 bits
      but did not understand why there was this split, and wrote 0 followed by a
      single word.  We should at least zero the word following to have
      well-defined storage later.

      Sadly, after wandering aimlessly in the desert of unloved patches all
      those years, all attribution got lost. This adds a copyright + license
      to scripts/bin2c.c, which hasn't aged a day.
