  • deb21db77   VFS: swap do_ioctl and vfs_ioctl names ... Browse Code »

    Rename old vfs_ioctl to do_ioctl, because the comment above it clearly
    indicates that it is an internal function not to be exported to modules;
    therefore it should have a more traditional do_XXX name. The new do_ioctl
    is exported in fs.h but not to modules.

    Rename the old do_ioctl to vfs_ioctl because the names vfs_XXX should
    preferably be reserved to callable VFS functions which modules may call, as
    many other vfs_XXX functions already do. Export the new vfs_ioctl to GPL
    modules so others can use it (including Unionfs and eCryptfs). Add DocBook
    for new vfs_ioctl.

  • 3fee37c1e   fix: using joysticks in 32 bit applications on 64 bit systems ... Browse Code »

    unfortunately 32 bit apps don't see the joysticks on a 64 bit system.
    this prevents one playing X-Plane (http://www.x-plane.com/) or other
    32-bit games with joysticks.

    this is a known issue, and already raised several times:

    http://readlist.com/lists/vger.kernel.org/linux-kernel/28/144411.html

    http://www.brettcsmith.org/wiki/wiki.cgi?action=browse&diff=1&id=OzyComputer/Joystick

    unfortunately this is still not fixed in the mainline kernel.

    it would be nice to have this fixed, so that people can play these games
    without having to patch their kernel.

    the following patch solves the problem on 2.6.22.

  • 32da477a5   [NET]: Don't implement dev_ifname32 inline ... Browse Code »

    The current implementation of dev_ifname makes maintenance difficult
    because updates to the implementation of the ioctl have to made in two
    places. So this patch updates dev_ifname32 to do a classic 32/64
    structure conversion and call sys_ioctl like the rest of the
    compat calls do.

  • f4d43bd57   fix compat console unimap regression ... Browse Code »

    Why is it that since the 2f1a2ccb9c0de632ab07193becf5f7121794f6ae console
    UTF-8 fixes went into 2.6.22-rc1, the PowerMac G5 shows only inverse video
    question marks for the text on tty2-6? whereas tty1 is fine, and so is x86.

    No fault of that patch: by removing the old fallback behaviour, it reveals
    that 32-bit setfont running on 64-bit kernels has only really worked on
    the current console, the rest getting faked by that inadequate fallback.

    Bring the compat do_unimap_ioctl into line with the main one: PIO_UNIMAP
    and GIO_UNIMAP apply to the specified tty, not redirected to fg_console.
    Use the same checks, and most particularly, remember to check access_ok:
    con_set_unimap and con_get_unimap are using __get_user and __put_user.

    And the compat vt_check should ask for the same capability as the main
    one, CAP_SYS_TTY_CONFIG rather than CAP_SYS_ADMIN. Added in vt_ioctl's
    vc_cons_allocated check for safety, though failure may well be impossible.

  • d9de2622b   Allow compat_ioctl.c to compile without CONFIG_NET ... Browse Code »

    A small regression appears to have been introduced in the recent patch
    "cleanup compat ioctl handling", which was included in Linus' tree after
    2.6.20.

    siocdevprivate_ioctl() is no longer defined if CONFIG_NET is undefined,
    whereas previously it was a dummy function in this case.

    This causes compilation with CONFIG_COMPAT but without CONFIG_NET to fail.

    fs/compat_ioctl.c: In function `compat_sys_ioctl':
    fs/compat_ioctl.c:3571: warning: implicit declaration of function `siocdevprivate_ioctl'

  • 0f7fc9e4d   [PATCH] VFS: change struct file to use struct path ... Browse Code »

    This patch changes struct file to use struct path instead of having
    independent pointers to struct dentry and struct vfsmount, and converts all
    users of f_{dentry,vfsmnt} in fs/ to use f_path.{dentry,mnt}.

    Additionally, it adds two #define's to make the transition easier for users of
    the f_dentry and f_vfsmnt.

  • 39484e53b   [PATCH] 32-bit compatibility HDIO IOCTLs ... Browse Code »

    A couple of HDIO IOCTLs are not yet handled and a few others are marked
    as using a pointer rather than an unsigned long. The formers include:

    HDIO_GET_WCACHE, HDIO_GET_ACOUSTIC, HDIO_GET_ADDRESS and
    HDIO_GET_BUSSTATE. The latters are: HDIO_SET_MULTCOUNT,
    HDIO_SET_UNMASKINTR, HDIO_SET_KEEPSETTINGS, HDIO_SET_32BIT,
    HDIO_SET_NOWERR, HDIO_SET_DMA, HDIO_SET_PIO_MODE and HDIO_SET_NICE.

    Additionally 0x330 used to be HDIO_GETGEO_BIG and may be issued by 32-bit
    `hdparm' run on a 64-bit kernel making Linux complain loudly.

    This is a fix for these issues.

    The ncp specific compat ioctls are clearly local to one file system, so the

  • 9361401eb   [PATCH] BLOCK: Make it possible to disable the block layer [try #6] ... Browse Code »

    Make it possible to disable the block layer. Not all embedded devices require
    it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require
    the block layer to be present.

    This patch does the following:

    (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev
    support.

    (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls
    an item that uses the block layer. This includes:

    (*) Block I/O tracing.

    (*) Disk partition code.

    (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS.

    (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the
    block layer to do scheduling. Some drivers that use SCSI facilities -
    such as USB storage - end up disabled indirectly from this.

    (*) Various block-based device drivers, such as IDE and the old CDROM
    drivers.

    (*) MTD blockdev handling and FTL.

    (*) JFFS - which uses set_bdev_super(), something it could avoid doing by
    taking a leaf out of JFFS2's book.

    (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and
    linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is,
    however, still used in places, and so is still available.

    (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and
    parts of linux/fs.h.

    (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.

    (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.

    (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK
    is not enabled.

    (*) fs/no-block.c is created to hold out-of-line stubs and things that are
    required when CONFIG_BLOCK is not set:

    (*) Default blockdev file operations (to give error ENODEV on opening).

    (*) Makes some /proc changes:

    (*) /proc/devices does not list any blockdevs.

    (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.

    (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.

    (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if
    given command other than Q_SYNC or if a special device is specified.

    (*) In init/do_mounts.c, no reference is made to the blockdev routines if
    CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2.

    (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return
    error ENOSYS by way of cond_syscall if so).

    (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if
    CONFIG_BLOCK is not set, since they can't then happen.
