      ext4: fix ext4_count_free_clusters() with EXT4FS_DEBUG and bigalloc enabled · 036acea2
      Azat Khuzhin authored
      With bigalloc enabled we must use EXT4_CLUSTERS_PER_GROUP() instead of
      EXT4_BLOCKS_PER_GROUP() otherwise we will go beyond the allocated buffer.

      ext4: move ext4_update_i_disksize() into mpage_map_and_submit_extent() · 622cad13
      Theodore Ts'o authored
      The function ext4_update_i_disksize() is used in only one place, in
      the function mpage_map_and_submit_extent().  Move its code to simplify
      the code paths, and also move the call to ext4_mark_inode_dirty() into
      the i_data_sem's critical region, to be consistent with all of the
      other places where we update i_disksize.  That way, we also keep the
      raw_inode's i_disksize protected, to avoid the following race:
      
            CPU #1                                 CPU #2
      
         down_write(&i_data_sem)
         Modify i_disk_size
         up_write(&i_data_sem)
                                              down_write(&i_data_sem)
                                              Modify i_disk_size
                                              Copy i_disk_size to on-disk inode

      ext4: fix COLLAPSE_RANGE test failure in data journalling mode · 1ce01c4a
      Namjae Jeon authored
      When mounting ext4 with data=journal option, xfstest shared/002 and
      shared/004 are currently failing as checksum computed for testfile
      does not match with the checksum computed in other journal modes.
      In case of data=journal mode, a call to filemap_write_and_wait_range
      will not flush anything to disk as buffers are not marked dirty in
      write_end. In collapse range this call is followed by a call to
      truncate_pagecache_range. Due to this, when checksum is computed,
      a portion of file is re-read from disk which replace valid data with
      NULL bytes and hence the reason for the difference in checksum.
      
      Calling ext4_force_commit before filemap_write_and_wait_range solves
      the issue as it will mark the buffers dirty during commit transaction
      which can be later synced by a call to filemap_write_and_wait_range.

      ext4: update PF_MEMALLOC handling in ext4_write_inode() · 87f7e416
      Theodore Ts'o authored
      The special handling of PF_MEMALLOC callers in ext4_write_inode()
      shouldn't be necessary as there shouldn't be any. Warn about it. Also
      update comment before the function as it seems somewhat outdated.
      
      (Changes modeled on an ext3 patch posted by Jan Kara to the linux-ext4
      mailing list on Februaryt 28, 2014, which apparently never went into
      the ext3 tree.)

      The reason for the warning is that buffer_head passed into
      jbd2_journal_dirty_metadata() didn't have journal_head attached. This is
      caused by the following race of two ext4_xattr_release_block() calls:
      
      CPU1                                CPU2
      ext4_xattr_release_block()          ext4_xattr_release_block()
      lock_buffer(bh);
      /* False */
      if (BHDR(bh)->h_refcount == cpu_to_le32(1))
      } else {
        le32_add_cpu(&BHDR(bh)->h_refcount, -1);
        unlock_buffer(bh);
                                          lock_buffer(bh);
                                          /* True */
                                          if (BHDR(bh)->h_refcount == cpu_to_le32(1))
                                            get_bh(bh);
                                            ext4_free_blocks()
                                              ...
                                              jbd2_journal_forget()
                                                jbd2_journal_unfile_buffer()
                                                -> JH is gone
        error = ext4_handle_dirty_xattr_block(handle, inode, bh);
        -> triggers the warning
      
      We fix the problem by moving ext4_handle_dirty_xattr_block() under the
      buffer lock. Sadly this cannot be done in nojournal mode as that
      function can call sync_dirty_buffer() which would deadlock. Luckily in
      nojournal mode the race is harmless (we only dirty already freed buffer)
      and thus for nojournal mode we leave the dirtying outside of the buffer
      lock.

      ext4_end_bio() currently throws away the error that it receives.  Chances
      are this is part of a spate of errors, one of which will end up getting
      the error returned to userspace somehow, but we shouldn't take that risk.
      Also print out the errno to aid in debug.

      ext4: initialize multi-block allocator before checking block descriptors · 00764937
      Azat Khuzhin authored
      With EXT4FS_DEBUG ext4_count_free_clusters() will call
      ext4_read_block_bitmap() without s_group_info initialized, so we need to
      initialize multi-block allocator before.
      
      And dependencies that must be solved, to allow this:
      - multi-block allocator needs in group descriptors
      - need to install s_op before initializing multi-block allocator,
        because in ext4_mb_init_backend() new inode is created.
      - initialize number of group desc blocks (s_gdb_count) otherwise
        number of clusters returned by ext4_free_clusters_after_init() is not correct.
        (see ext4_bg_num_gdb_nometa())
      
      Here is the stack backtrace:

      in ext4_ext_put_gap_in_cache().
      
      To avoid the problem, ext4_map_blocks() needs to check the file logical block
      number. ext4_ext_put_gap_in_cache() called via ext4_map_blocks() cannot
      handle 2^32-1 because the maximum file logical block number is 2^32-2.
      
      Note that ext4_ind_map_blocks() returns -EIO when the block number is invalid.
      So ext4_map_blocks() should also return the same errno.

       "There are a couple of new fallocate features in this request - it was
        decided that it was easiest to push them through the XFS tree using
        topic branches and have the ext4 support be based on those branches.
        Hence you may see some overlap with the ext4 tree merge depending on
        how they including those topic branches into their tree.  Other than
        that, there is O_TMPFILE support, some cleanups and bug fixes.
      
        The main changes in the XFS tree for 3.15-rc1 are:
      
         - O_TMPFILE support
         - allowing AIO+DIO writes beyond EOF
         - FALLOC_FL_COLLAPSE_RANGE support for fallocate syscall and XFS
           implementation

       "One of the main highlights this time, is not the patches themselves
        but instead the widening contributor base.  It is good to see that
        interest is increasing in GFS2, and I'd like to thank all the
        contributors to this patch set.
      
        In addition to the usual set of bug fixes and clean ups, there are
        patches to improve inode creation performance when xattrs are required
        and some improvements to the transaction code which is intended to
        help improve scalability after further changes in due course.
      
        Journal extent mapping is also updated to make it more efficient and
        again, this is a foundation for future work in this area.
      
        The maximum number of ACLs has been increased to 300 (for a 4k block
        size) which means that even with a few additional xattrs from selinux,
        everything should fit within a single fs block.
      
        There is also a patch to bring GFS2's own copy of the writepages code
        up to the same level as the core VFS.  Eventually we may be able to
        merge some of this code, since it is fairly similar.

       "Main batch of InfiniBand/RDMA changes for 3.15:
      
         - The biggest change is core API extensions and mlx5 low-level driver
           support for handling DIF/DIX-style protection information, and the
           addition of PI support to the iSER initiator.  Target support will
           be arriving shortly through the SCSI target tree.
      
         - A nice simplification to the "umem" memory pinning library now that
           we have chained sg lists.  Kudos to Yishai Hadas for realizing our
           code didn't have to be so crazy.
      
         - Another nice simplification to the sg wrappers used by qib, ipath
           and ehca to handle their mapping of memory to adapter.
      
         - The usual batch of fixes to bugs found by static checkers etc.

      Linus Torvalds authored
      Pull bulk of gpio updates from Linus Walleij:
       "A pretty big chunk of changes this time, but it has all been on
        rotation in linux-next and had some testing.  Of course there will be
        some amount of fixes on top...
      
         - Merged in a branch of irqchip changes from Thomas Gleixner: we need
           to have new callbacks from the irqchip to determine if the GPIO
           line will be eligible for IRQs, and this callback must be able to
           say "no".  After some thinking I got the branch from tglx and have
           switched all current users over to use this.
      
         - Based on tglx patches, we have added some generic irqchip helpers
           in the gpiolib core.  These will help centralize code when GPIO
           drivers have simple chained/cascaded IRQs.  Drivers will still
           define their irqchip vtables, but the gpiolib core will take care
           of irqdomain set-up, mapping from local offsets to Linux irqs, and
           reserve resources by marking the GPIO lines for IRQs.
      
         - Initially the PL061 and Nomadik GPIO/pin control drivers have been
           switched over to use the new gpiochip-to-irqchip infrastructure
           with more drivers expected for the next kernel cycle.  The
           factoring of just two drivers still makes it worth it so it is
           already a win.
      
         - A new driver for the Synopsys DesignWare APB GPIO block.
      
         - Modify the DaVinci GPIO driver to be reusable also for the new TI
           Keystone architecture.
      
         - A new driver for the LSI ZEVIO SoCs.
      
         - Delete the obsolte tnetv107x driver.
      
         - Some incremental work on GPIO descriptors: have
           gpiod_direction_output() use a logical level, respecting assertion
           polarity through ACTIVE_LOW flags, adding gpiod_direction_output_raw()
           for the case where you want to set that very value.  Add
           gpiochip_get_desc() to fetch a GPIO descriptor from a specific
           offset on a certain chip inside driver code.
      
         - Switch ACPI GPIO code over to using gpiochip_get_desc() and get rid
           of gpio_to_desc().
      
         - The ACPI GPIO event handling code has been reworked after
           encountering an actual real life implementation.
      
         - Support for ACPI GPIO operation regions.
      
         - Generic GPIO chips can now be assigned labels/names from platform
           data.
      
         - We now clamp values returned from GPIO drivers to the boolean [0,1]
           range.
      
         - Some improved documentation on how to use the polarity flag was
           added.
      
         - a large slew of incremental driver updates and non-critical fixes.
           Some targeted for stable"
