  • d1e183c8d   console/font: Refactor font support code selection logic ... Browse Code »

    The current Makefile rules to build font support are messy and buggy.
    Replace them by Kconfig rules:
    - Introduce CONFIG_FONT_SUPPORT, which controls the building of all font
    code,
    - Select CONFIG_FONT_SUPPORT for all drivers that use fonts,
    - Select CONFIG_FONT_8x16 for all drivers that default to the VGA8x16
    font,
    - Drop the bogus console dependency for CONFIG_VIDEO_VIVI,
    - Always process drivers/video/console/Makefile, as some drivers need
    fonts even if CONFIG_VT is not set.

    This fixes (if CONFIG_SOLO6X10=y and there are no built-in console
    drivers):

    drivers/built-in.o: In function `solo_osd_print':
    drivers/staging/media/solo6x10/solo6x10-enc.c:144: undefined reference to `.find_font'

    This fixes (if CONFIG_VT=n):

    drivers/built-in.o: In function `vivi_init':
    vivi.c:(.init.text+0x1a3da): undefined reference to `find_font'

    A failed kzalloc() is reported with a dev_err that dereferences the null
    sisusb, this will cause a NULL pointer deference error.

    Instead, pass dev->dev to the dev_err() rather than &sisusb->sisusb_dev->dev

    Smatch analysis:

    drivers/usb/misc/sisusbvga/sisusb.c:3087 sisusb_probe() error: potential null
    dereference 'sisusb'. (kzalloc returns null)

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • d2fb1bb32   USB: sisusbvga: drop usb_buffer_alloc ... Browse Code »

    This patch falls out of my work to fix usbmon so it uses virtual addresses.
    It is not necessary, the "new" usbmon should work just fine with sisusbvga.
    However, it seems ridiculous that anyone would use uncached memory to
    transfer bulk data. Dropping the unnecessary use of usb_buffer_alloc
    should be beneficial here, in case anyone ever uses the dongle on
    anything beyond x86.

    I had no success in raising the author of the driver by e-mail, so
    the patch is not actually tested.

  • e400b6ec4   vt/vgacon: Check if screen resize request comes from userspace ... Browse Code »

    Various console drivers are able to resize the screen via the con_resize()
    hook. This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and
    VT_RESIZEX ioctl's. One particular utility, SVGATextMode, expects that
    con_resize() of the VGA console will always return success even if the
    resulting screen is not compatible with the hardware. However, this
    particular behavior of the VGA console, as reported in Kernel Bugzilla Bug
    7513, can cause undefined behavior if the user starts with a console size
    larger than 80x25.

    To work around this problem, add an extra parameter to con_resize(). This
    parameter is ignored by drivers except for vgacon. If this parameter is
    non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl
    and vgacon will always return success. If this parameter is zero, vgacon will
    return -EINVAL if the requested size is not compatible with the hardware. The
    latter is the more correct behavior.

    With this change, SVGATextMode should still work correctly while in-kernel and
    stty resize calls can expect correct behavior from vgacon.
