  • e6305c43e   [PATCH] sanitize ->permission() prototype ... Browse Code »

    * kill nameidata * argument; map the 3 bits in ->flags anybody cares
    about to new MAY_... ones and pass with the mask.
    * kill redundant gfs2_iop_permission()
    * sanitize ecryptfs_permission()
    * fix remaining places where ->permission() instances might barf on new
    MAY_... found in mask.

    The obvious next target in that direction is permission(9)

    folded fix for nfs_permission() breakage from Miklos Szeredi

  • 51cc50685   SL*B: drop kmem cache argument from constructor ... Browse Code »

    Kmem cache passed to constructor is only needed for constructors that are
    themselves multiplexeres. Nobody uses this "feature", nor does anybody uses
    passed kmem cache in non-trivial way, so pass only pointer to object.

    Non-trivial places are:
    arch/powerpc/mm/init_64.c
    arch/powerpc/mm/hugetlbpage.c

    This is flag day, yes.

  • 74abb9890   quota: move function-macros from quota.h to quotaops.h ... Browse Code »

    Move declarations of some macros, which should be in fact functions to
    quotaops.h. This way they can be later converted to inline functions
    because we can now use declarations from quota.h. Also add necessary
    includes of quotaops.h to a few files.

    The comment above the function says one of its return value is -EIO,
    and also the caller of diAlloc() checks for -EIO:

    rc = diAlloc(parent, S_ISDIR(mode), inode);

  • eab1df71a   iget: stop JFS from using iget() and read_inode() ... Browse Code »

    Stop the JFS filesystem from using iget() and read_inode(). Replace
    jfs_read_inode() with jfs_iget(), and call that instead of iget(). jfs_iget()
    then uses iget_locked() directly and returns a proper error code instead of an
    inode in the event of an error.

    jfs_fill_super() returns any error incurred when getting the root inode
    instead of EINVAL.

  • e47776a0a   Forbid user to change file flags on quota files ... Browse Code »

    Forbid user from changing file flags on quota files. User has no bussiness
    in playing with these flags when quota is on. Furthermore there is a
    remote possibility of deadlock due to a lock inversion between quota file's
    i_mutex and transaction's start (i_mutex for quota file is locked only when
    trasaction is started in quota operations) in ext3 and ext4.

    the order of the arguments is opposite to other slab functions. The object

    Implement nobh in new aops. This is a bit tricky. FWIW, nobh_truncate is
    now implemented in a way that does not create blocks in sparse regions,
    which is a silly thing for it to have been doing (isn't it?)

    ext2 survives fsx and fsstress. jfs is converted as well... ext3
    should be easy to do (but not done yet).

  • 6712ecf8f   Drop 'size' argument from bio_endio and bi_end_io ... Browse Code »

    As bi_end_io is only called once when the reqeust is complete,
    the 'size' argument is now redundant. Remove it.

    Now there is no need for bio_endio to subtract the size completed
    from bi_size. So don't do that either.

    While we are at it, change bi_end_io to return void.

  • 20c2df83d   mm: Remove slab destructors from kmem_cache_create(). ... Browse Code »

    Slab destructors were no longer supported after Christoph's
    c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
    BUGs for both slab and slub, and slob never supported them
    either.

    This rips out support for the dtor pointer from kmem_cache_create()
    completely and fixes up every single callsite in the kernel (there were
    about 224, not including the slab allocator definitions themselves,
    or the documentation references).

  • 3bd858ab1   Introduce is_owner_or_cap() to wrap CAP_FOWNER use with fsuid check ... Browse Code »

    Introduce is_owner_or_cap() macro in fs.h, and convert over relevant
    users to it. This is done because we want to avoid bugs in the future
    where we check for only effective fsuid of the current task against a
    file's owning uid, without simultaneously checking for CAP_FOWNER as
    well, thus violating its semantics.
    [ XFS uses special macros and structures, and in general looked ...
    untouchable, so we leave it alone -- but it has been looked over. ]

    The (current->fsuid != inode->i_uid) check in generic_permission() and
    exec_permission_lite() is left alone, because those operations are
    covered by CAP_DAC_OVERRIDE and CAP_DAC_READ_SEARCH. Similarly operations
    falling under the purview of CAP_CHOWN and CAP_LEASE are also left alone.
