  • f34d7a5b7   tty: The big operations rework ... Browse Code »

    - Operations are now a shared const function block as with most other Linux
    objects

    - Introduce wrappers for some optional functions to get consistent behaviour

    - Wrap put_char which used to be patched by the tty layer

    - Document which functions are needed/optional

    - Make put_char report success/fail

    - Cache the driver->ops pointer in the tty as tty->ops

    - Remove various surplus lock calls we no longer need

    - Remove proc_write method as noted by Alexey Dobriyan

    - Introduce some missing sanity checks where certain driver/ldisc
    combinations would oops as they didn't check needed methods were present

  • 04f378b19   tty: BKL pushdown ... Browse Code »

    - Push the BKL down into the line disciplines
    - Switch the tty layer to unlocked_ioctl
    - Introduce a new ctrl_lock spin lock for the control bits
    - Eliminate much of the lock_kernel use in n_tty
    - Prepare to (but don't yet) call the drivers with the lock dropped
    on the paths that historically held the lock

    BKL now primarily protects open/close/ldisc change in the tty layer

  • 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.

    different subsystems work with them - that have an absolutely horrid

  • 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.
