  • 7f78e0351   fs: Limit sys_mount to only request filesystem modules. ... Browse Code »

    Modify the request_module to prefix the file system type with "fs-"
    and add aliases to all of the filesystems that can be built as modules
    to match.

    A common practice is to build all of the kernel code and leave code
    that is not commonly needed as modules, with the result that many
    users are exposed to any bug anywhere in the kernel.

    Looking for filesystems with a fs- prefix limits the pool of possible
    modules that can be loaded by mount to just filesystems trivially
    making things safer with no real cost.

    Using aliases means user space can control the policy of which
    filesystem modules are auto-loaded by editing /etc/modprobe.d/*.conf
    with blacklist and alias directives. Allowing simple, safe,
    well understood work-arounds to known problematic software.

    This also addresses a rare but unfortunate problem where the filesystem
    name is not the same as it's module name and module auto-loading
    would not work. While writing this patch I saw a handful of such
    cases. The most significant being autofs that lives in the module
    autofs4.

    This is relevant to user namespaces because we can reach the request
    module in get_fs_type() without having any special permissions, and
    people get uncomfortable when a user specified string (in this case
    the filesystem type) goes all of the way to request_module.

    After having looked at this issue I don't think there is any
    particular reason to perform any filtering or permission checks beyond
    making it clear in the module request that we want a filesystem
    module. The common pattern in the kernel is to call request_module()
    without regards to the users permissions. In general all a filesystem
    module does once loaded is call register_filesystem() and go to sleep.
    Which means there is not much attack surface exposed by loading a
    filesytem module unless the filesystem is mounted. In a user
    namespace filesystems are not mounted unless .fs_flags = FS_USERNS_MOUNT,
    which most filesystems do not set today.

    Pull KGDB/KDB fixes and cleanups from Jason Wessel:
    "For a change we removed more code than we added. If people aren't
    using it we shouldn't be carrying it. :-)

    Cleanups:
    - Remove kdb ssb command - there is no in kernel disassembler to
    support it

    - Remove kdb ll command - Always caused a kernel oops and there were
    no bug reports so no one was using this command

    - Use kernel ARRAY_SIZE macro instead of array computations

    Fixes:
    - Stop oops in kdb if user executes kdb_defcmd with args

    - kdb help command truncated text

    - ppc64 support for kgdbts

    - Add missing kconfig option from original kdb port for dealing with
    catastrophic kernel crashes such that you can reboot automatically
    on continue from kdb"

  • e78acf67b   kgdb/kgdbts: support ppc64 ... Browse Code »

    We can't look up the address of the entry point of the function simply
    via that function symbol for all architectures.

    For PPC64 ABI, actually there is a function descriptors structure.

    A function descriptor is a three doubleword data structure that contains
    the following values:
    * The first doubleword contains the address of the entry point of
    the function.
    * The second doubleword contains the TOC base address for
    the function.
    * The third doubleword contains the environment pointer for
    languages such as Pascal and PL/1.

    So we should call a wapperred dereference_function_descriptor() to get
    the address of the entry point of the function.

    Note this is also safe for other architecture after refer to
    "include/asm-generic/sections.h" since:

    dereference_function_descriptor(p) always is (p) if without arched definition.

  • b67bfe0d4   hlist: drop the node parameter from iterators ... Browse Code »

    I'm not sure why, but the hlist for each entry iterators were conceived

    list_for_each_entry(pos, head, member)

    The hlist ones were greedy and wanted an extra parameter:

    hlist_for_each_entry(tpos, pos, head, member)

    Why did they need an extra pos parameter? I'm not quite sure. Not only
    they don't really need it, it also prevents the iterator from looking
    exactly like the list iterator, which is unfortunate.

    Besides the semantic patch, there was some manual work required:

    - Fix up the actual hlist iterators in linux/list.h
    - Fix up the declaration of other iterators based on the hlist ones.
    - A very small amount of places were using the 'node' parameter, this
    was modified to use 'obj->member' instead.
    - Coccinelle didn't handle the hlist_for_each_entry_safe iterator
    properly, so those had to be fixed up manually.

    The semantic patch which is mostly the work of Peter Senna Tschudin is here:

    @@
    iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host;

    Other than that, some random updates/fixes like USB-audio and a bunch
    of small AoC updates as usual.

    Highlights:

    - Unification of HD-audio parser code (aka generic parser)

    - Support of new Intel HD-audio controller, new IDT codecs

    - Fixes for HD-audio HDMI audio hotplug

    - Haswell HDMI audio fixup

    - Support of Creative CA0132 DSP code

    - A few fixes of HDSP driver

    - USB-audio fix for Roland A-PRO, M-Audio FT C600

    - Support PM for aloop driver (and fixes Oops)

    - Compress API updates for gapless playback support

    For ASoC part:

    - Support for a wider range of hardware in the compressed stream code

    - The ability to mute capture streams as well as playback streams
    while inactive

    - DT support for AK4642, FSI, Samsung I2S and WM8962

    - AC'97 support for Tegra

    - New driver for max98090, replacing the stub which was there

    - A new driver from Dialog

    Note that due to dependencies, DTification of DMA support for Samsung
    platforms (used only by the and I2S driver and SPI) is merged here as
    well."

  • a7e2ca170   Revert "drivers/misc/ti-st: remove gpio handling" ... Browse Code »

    This reverts commit eccf2979b2c034b516e01b8a104c3739f7ef07d1.

    The reason is that it broke TI WiLink shared transport on Panda.
    Also, callback functions should not be added to board files anymore,
    so revert to implementing the power functions in the driver itself.

    Additionally, changed a variable name ('status' to 'err') so that this
    revert compiles properly.

  • 1684789f8   misc: Convert to devm_ioremap_resource() ... Browse Code »

    Convert all uses of devm_request_and_ioremap() to the newly introduced
    devm_ioremap_resource() which provides more consistent error handling.

    devm_ioremap_resource() provides its own error messages so all explicit
    error messages can be removed from the failure code paths.

  • 5a19b7897   VMCI: Fix broken context ID retrieval ... Browse Code »

    I'm an idiot. The context ID can be a really large unsigned number, which
    means it'll appear negative as an int. So actually the right fix here is just
    to set it regardless of the returned value (but only for this particular
    hypercall; normally we would check it).

  • 4f73bc4dd   tty: Added a CONFIG_TTY option to allow removal of TTY ... Browse Code »

    The option allows you to remove TTY and compile without errors. This
    saves space on systems that won't support TTY interfaces anyway.
    bloat-o-meter output is below.

    The bulk of this patch consists of Kconfig changes adding "depends on
    TTY" to various serial devices and similar drivers that require the TTY
    layer. Ideally, these dependencies would occur on a common intermediate
    symbol such as SERIO, but most drivers "select SERIO" rather than
    "depends on SERIO", and "select" does not respect dependencies.

    bloat-o-meter output comparing our previous minimal to new minimal by
    removing TTY. The list is filtered to not show removed entries with awk
    '$3 != "-"' as the list was very long.
