  • The original dialog_inputbox doesn't work with longer than prompt_width
    strings, here fixed it in this way:
    1) add variable cursor_form_win to record cursor of form_win,
    keep its value always between [0, prompt_width-1];
    reuse the original cursor_position as cursor of the string result,
    use (cursor_position-cursor_form_win) as begin offset to show part of
    the string in form_win;

  • In case KEY_BACKSPACE / KEY_DC to delete a char, it memmove only
    (len-cursor_position+1) bytes;
    the default case is to insert a char, it should also memmove exactly
    (len-cursor_position+1) bytes;

    the original use of (len+1) is wrong and may access following memory
    that doesn't belong to result, may cause SegFault in theory;

    case KEY_BACKSPACE:
    if (cursor_position > 0) {
    memmove(&result[cursor_position-1],
    &result[cursor_position],
    len-cursor_position+1);
    cursor_position--;
    }
    break;
    case KEY_DC:
    if (cursor_position >= 0 && cursor_position < len) {
    memmove(&result[cursor_position],
    &result[cursor_position+1],
    len-cursor_position+1);
    }
    break;
    default:
    if ((isgraph(res) || isspace(res)) &&
    len-2 < result_len) {
    /* insert the char at the proper position */
    memmove(&result[cursor_position+1],
    &result[cursor_position],
    len-cursor_position+1);
    result[cursor_position] = res;
    cursor_position++;

  • The inode structure layout is largely random, and some of the vfs paths
    really do care. The path lookup in particular is already quite D$
    intensive, and profiles show that accessing the 'inode->i_op->xyz'
    fields is quite costly.

    We already optimized the dcache to not unnecessarily load the d_op
    structure for members that are often NULL using the DCACHE_OP_xyz bits
    in dentry->d_flags, and this does something very similar for the inode
    ops that are used during pathname lookup.

    It also re-orders the fields so that the fields accessed by 'stat' are
    together at the beginning of the inode structure, and roughly in the
    order accessed.

    The effect of this seems to be in the 1-2% range for an empty kernel
    "make -j" run (which is fairly kernel-intensive, mostly in filename
    lookup), so it's visible. The numbers are fairly noisy, though, and
    likely depend a lot on exact microarchitecture. So there's more tuning
    to be done.

  • Gcc tends to generate better code with small integers, including the
    DCACHE_xyz flag tests - so move the common ones to be first in the list.
    Also just remove the unused DCACHE_INOTIFY_PARENT_WATCHED and
    DCACHE_AUTOFS_PENDING values, their users no longer exists in the source
    tree.

    And add a "unlikely()" to the DCACHE_OP_COMPARE test, since we want the
    common case to be a nice straight-line fall-through.

  • ORE stands for "Objects Raid Engine"

    This patch is a mechanical rename of everything that was in ios.c
    and its API declaration to an ore.c and an osd_ore.h header. The ore
    engine will later be used by the pnfs objects layout driver.

    * File ios.c => ore.c

    * Declaration of types and API are moved from exofs.h to a new
    osd_ore.h

    * All used types are prefixed by ore_ from their exofs_ name.

    * Shift includes from exofs.h to osd_ore.h so osd_ore.h is
    independent, include it from exofs.h.

    Other than a pure rename there are no other changes. Next patch
    will move the ore into it's own module and will export the API
    to be used by exofs and later the layout driver

  • Exofs raid engine was saving on memory space by having a single layout-info,
    single pid, and a single device-table, global to the filesystem. Then passing
    a credential and object_id info at the io_state level, private for each
    inode. It would also devise this contraption of rotating the device table
    view for each inode->ino to spread out the device usage.

    This is not compatible with the pnfs-objects standard, demanding that
    each inode can have it's own layout-info, device-table, and each object
    component it's own pid, oid and creds.

    So: Bring exofs raid engine to be usable for generic pnfs-objects use by:

    * Define an exofs_comp structure that holds obj_id and credential info.

    * Break up exofs_layout struct to an exofs_components structure that holds a
    possible array of exofs_comp and the array of devices + the size of the
    arrays.

    * Add a "comps" parameter to get_io_state() that specifies the ids creds
    and device array to use for each IO.

    This enables to keep the layout global, but the device-table view, creds
    and IDs at the inode level. It only adds two 64bit to each inode, since
    some of these members already existed in another form.

    * ios raid engine now access layout-info and comps-info through the passed
    pointers. Everything is pre-prepared by caller for generic access of
    these structures and arrays.

    At the exofs Level:

    * Super block holds an exofs_components struct that holds the device
    array, previously in layout. The devices there are in device-table
    order. The device-array is twice bigger and repeats the device-table
    twice so now each inode's device array can point to a random device
    and have a round-robin view of the table, making it compatible to
    previous exofs versions.

    * Each inode has an exofs_components struct that is initialized at
    load time, with it's own view of the device table IDs and creds.
    When doing IO this gets passed to the io_state together with the
    layout.

    While preforming this change. Bugs where found where credentials with the
    wrong IDs where used to access the different SB objects (super.c). As well
    as some dead code. It was never noticed because the target we use does not
    check the credentials.

  • ios.c will be moving to an external library, for use by the
    objects-layout-driver. Remove from it some exofs specific functions.

    Also g_attr_logical_length is used both by inode.c and ios.c
    move definition to the later, to keep it independent

  • In future raid code we will need to know the IO offset/length
    and if it's a read or write to determine some of the array
    sizes we'll need.

    So add a new exofs_get_rw_state() API for use when
    writeing/reading. All other simple cases are left using the
    old way.

    The major change to this is that now we need to call
    exofs_get_io_state later at inode.c::read_exec and
    inode.c::write_exec when we actually know these things. So this
    patch is kept separate so I can test things apart from other
    changes.

  • Computers have become a lot faster since we compromised on the
    partial MD4 hash which we use currently for performance reasons.

    MD5 is a much safer choice, and is inline with both RFC1948 and
    other ISS generators (OpenBSD, Solaris, etc.)

    Furthermore, only having 24-bits of the sequence number be truly
    unpredictable is a very serious limitation. So the periodic
    regeneration and 8-bit counter have been removed. We compute and
    use a full 32-bit sequence number.

    For ipv6, DCCP was found to use a 32-bit truncated initial sequence
    number (it needs 43-bits) and that is fixed here as well.
