      [S390] revert add_active_range() usage patch. · bcc8bcb1
      Heiko Carstens authored
      Commit 7676bef9 breaks DCSS support on
      s390. DCSS needs initialized struct pages to work. With the usage of
      add_active_range() only the struct pages for physically present pages
      are initialized.
      This could be fixed if the DCSS driver would initiliaze the struct pages
      itself, but this doesn't work too. This is because the mem_map array
      does not include holes after the last present memory area and therefore
      there is nothing that could be initialized.
      To fix this and to avoid some dirty hacks revert this patch for now.
      Will be added later when we move to a virtual mem_map.

      [SPARC]: Fix robust futex syscalls and wire up migrate_pages. · 59359ff8
      David S. Miller authored
      When I added the entries for the robust futex syscall entries, I
      forgot to bump NR_SYSCALLS.  The current situation is error-prone
      because NR_SYSCALLS lives in entry.S where the system call limit
      checks are enforced.  Move the definition to asm/unistd.h in order to
      make this mistake much more difficult to make.
      
      And wire up sys_migrate_pages since the powerpc folks implemented the
      compat wrapper for us.

      [PATCH] Fix user.* xattr permission check for sticky dirs · f1f2d871
      Andreas Gruenbacher authored
      The user.* extended attributes are only allowed on regular files and
      directories.  Sticky directories further restrict write access to the owner
      and privileged users.  (See the attr(5) man page for an explanation.)
      
      The original check in ext2/ext3 when user.* xattrs were merged was more
      restrictive than intended, and when the xattr permission checks were moved
      into the VFS, read access to user.* attributes on sticky directores ended
      up being denied in addition.

      [PATCH] Fix sys_move_pages when a NULL node list is passed · 8ce08464
      Stephen Rothwell authored
      sys_move_pages() uses vmalloc() to allocate an array of structures that is
      fills with information passed from user mode and then passes to
      do_stat_pages() (in the case the node list is NULL).  do_stat_pages()
      depends on a marker in the node field of the structure to decide how large
      the array is and this marker is correctly inserted into the last element of
      the array.  However, vmalloc() doesn't zero the memory it allocates and if
      the user passes NULL for the node list, then the node fields are not filled
      in (except for the end marker).  If the memory the vmalloc() returned
      happend to have a word with the marker value in it in just the right place,
      do_pages_stat will fail to fill the status field of part of the array and
      we will return (random) kernel data to user mode.

      [PATCH] uml: include tidying · 1f6f6164
      Jeff Dike authored
      In order to get the __NR_* constants, we need sys/syscall.h.
      linux/unistd.h works as well since it includes syscall.h, however syscall.h
      is more parsimonious.  We were inconsistent in this, and this patch adds
      syscall.h includes where necessary and removes linux/unistd.h includes
      where they are not needed.
      
      asm/unistd.h also includes the __NR_* constants, but these are not the
      glibc-sanctioned ones, so this also removes one such inclusion.

      [PATCH] uml: fix I/O hang · 53b17332
      Jeff Dike authored
      Fix a UML hang in which everything would just stop until some I/O happened
      - a ping, someone whacking the keyboard - at which point everything would
      start up again as though nothing had happened.
      
      The cause was gcc reordering some code which absolutely needed to be
      executed in the order in the source.  When unblock_signals switches signals
      from off to on, it needs to see if any interrupts had happened in the
      critical section.  The interrupt handlers check signals_enabled - if it is
      zero, then the handler adds a bit to the "pending" bitmask and returns.
      unblock_signals checks this mask to see if any signals need to be
      delivered.
      
      The crucial part is this:
      	signals_enabled = 1;
      	save_pending = pending;
      	if(save_pending == 0)
      		return;
      	pending = 0;
      
      In order to avoid an interrupt arriving between reading pending and setting
      it to zero, in which case, the record of the interrupt would be erased,
      signals are enabled.
      
      What happened was that gcc reordered this so that 'save_pending = pending'
      came before 'signals_enabled = 1', creating a one-instruction window within
      which an interrupt could arrive, set its bit in pending, and have it be
      immediately erased.
      
      When the I/O workload is purely disk-based, the loss of a block device
      interrupt stops the entire I/O system because the next block request will
      wait for the current one to finish.  Thus the system hangs until something
      else causes some I/O to arrive, such as a network packet or console input.
      
      The fix to this particular problem is a memory barrier between enabling
      signals and reading the pending signal mask.  An xchg would also probably
      work.
      
      Looking over this code for similar problems led me to do a few more
      things:
      
      - make signals_enabled and pending volatile so that they don't get cached
        in registers
      
      - add an mb() to the return paths of block_signals and unblock_signals so
        that the modification of signals_enabled doesn't get shuffled into the
        caller in the event that these are inlined in the future.

      [PATCH] reiserfs: reset errval after initializing bitmap cache · d2c89a42
      Jeff Mahoney authored
      Callers after reiserfs_init_bitmap_cache() expect errval to contain -EINVAL
      until much later.  If a condition fails before errval is reset later,
      reiserfs_fill_super() will mistakenly return 0, causing an Oops in
      do_add_mount().  This patch resets errval to -EINVAL after the call.
      
      I view this as a temporary fix and real error codes should be used
      throughout reiserfs_fill_super().

        ===================================================================
      
      Cause for this problem was,2 successive mutex_lock calls on 2 diffrent inodes ,as shown below
      
      	static int
      	nfsd4_clear_clid_dir(struct dentry *dir, struct dentry *dentry)
      	{
      	        int status;
      
      	        /* For now this directory should already be empty, but we empty it of
              	 * any regular files anyway, just in case the directory was created by
      	         * a kernel from the future.... */
              	nfsd4_list_rec_dir(dentry, nfsd4_remove_clid_file);
      	        mutex_lock(&dir->d_inode->i_mutex);
      	        status = vfs_rmdir(dir->d_inode, dentry);
      	...
      
      	int vfs_rmdir(struct inode *dir, struct dentry *dentry)
      	{
      	        int error = may_delete(dir, dentry, 1);
      
      	        if (error)
      	                return error;
      
      	        if (!dir->i_op || !dir->i_op->rmdir)
              	        return -EPERM;
      
      	        DQUOT_INIT(dir);
      
      	        mutex_lock(&dentry->d_inode->i_mutex);
      	...
      
      So I have developed the patch to overcome this problem.
