  • 764a5c6b1   xattr handlers: Simplify list operation ... Browse Code »

    Change the list operation to only return whether or not an attribute
    should be listed. Copying the attribute names into the buffer is moved
    to the callers.

    Since the result only depends on the dentry and not on the attribute
    name, we do not pass the attribute name to list operations.

  • d9a82a040   xattr handlers: Pass handler to operations instead of flags ... Browse Code »

    The xattr_handler operations are currently all passed a file system
    specific flags value which the operations can use to disambiguate between
    different handlers; some file systems use that to distinguish the xattr
    namespace, for example. In some oprations, it would be useful to also have
    access to the handler prefix. To allow that, pass a pointer to the handler
    to operations instead of the flags value alone.

    Pull MTD updates from Brian Norris:
    "Common MTD:

    - Add Kconfig option for keeping both the 'master' and 'partition'
    MTDs registered as devices. This would really make a better
    default if we could do it over, as it allows a lot more flexibility
    in (1) determining the flash topology of the system from user-space
    and (2) adding temporary partitions at runtime (ioctl(BLKPG)).

    Unfortunately, this would possibly cause user-space breakage, as it
    will cause renumbering of the /dev/mtdX devices. We'll see if we
    can change this in the future, as there have already been a few
    people looking for this feature, and I know others have just been
    working around our current limitations instead of fixing them this
    way.

    - Along with the previous change, add some additional information to
    sysfs, so user-space can read the offset of each partition within
    its master device

    SPI NOR:

    - add new device tree compatible binding to represent the
    mostly-compatible class of SPI NOR flash which can be detected by
    their extended JEDEC ID bytes, cutting down the duplication of our
    ID tables

  • 8c5a03664   jffs2: allow to complete xattr integrity check on first GC scan ... Browse Code »

    Unlike file data integrity the xattr data integrity was not checked
    before some explicit access to the attribute was made.

    This could leave in the system a number of corrupted extended attributes
    which will be detected only at access time and possibly at a very late
    time compared to the time the corruption actually happened.

    This patch adds the ability to check for extended attribute integrity
    on first GC scan pass (similar to file data integrity check). This allows
    for all present attributes to be completly verified before any use of them.

    In order to work correctly this patch also needs the patch allowing
    JFFS2 to discriminate between recoverable and non recoverable errors
    on extended attributes.

  • 9824f75d5   jffs2: allow to discriminate between recoverable and non-recoverable errors ... Browse Code »

    This patch is basically a revert of commit f326966b3df47f4fa7e90425f60efdd30c31fe19.

    It allows JFFS2 to make the distinction between a potential transient
    error (reading or writing the media) and a non recoverable error like a
    bad CRC on the extended attribute data or some insconsitent parameters.

    In order to make clear that the error is indeed intended to report a
    corrupted attribute, a new local error code (JFFS2_XATTR_IS_CORRUPTED)
    is introduced rather than returning a confusing positive EIO, which is
    what led to the inappropriate "fix" last time.

    This error code is never reported to user space and only checked locally
    in this file.

  • 431547b3c   sanitize xattr handler prototypes ... Browse Code »

    Add a flags argument to struct xattr_handler and pass it to all xattr
    handler methods. This allows using the same methods for multiple
    handlers, e.g. for the ACL methods which perform exactly the same action
    for the access and default ACLs, just using a different underlying
    attribute. With a little more groundwork it'll also allow sharing the
    methods for the regular user/trusted/secure handlers in extN, ocfs2 and
    jffs2 like it's already done for xfs in this patch.

    Also change the inode argument to the handlers to a dentry to allow
    using the handlers mechnism for filesystems that require it later,
    e.g. cifs.

  • 8ae5d3126   [JFFS2] Fix BUG() caused by failing to discard xattrs on deleted files. ... Browse Code »

    When we cannot mark nodes as obsolete, such as on NAND flash, we end up
    having to delete inodes with !nlink in jffs2_build_remove_unlinked_inode().
    However, jffs2_build_xattr_subsystem() runs later than this, and will
    attach an xref to the dead inode. Then later when the last nodes of that
    dead inode are erased we hit a BUG() in jffs2_del_ino_cache()
    because we're not supposed to get there with an xattr still attached to
    the inode which is being killed.

    The simple fix is to refrain from attaching xattrs to inodes with zero
    nlink, in jffs2_build_xattr_subsystem(). It's it's OK to trust nlink
    here because the file system isn't actually mounted yet, so there's no
    chance that a zero-nlink file could actually be alive still because
    it's open.

    Previously, it's only called when xd->refcnt equals zero.
    (calling it with positive xd->refcnt cause a BUG())
    If you applied this patch, the function checks whether
    xd->refcnt is zero or not under the spinlock if necessary.
    Then, it marks xd DEAD flahs and links with xattr_dead_list
    or releases it immediately when xd->refcnt become zero.
