  • f56141e3e   all arches, signal: move restart_block to struct task_struct ... Browse Code »
    19

    If an attacker can cause a controlled kernel stack overflow, overwriting
    the restart block is a very juicy exploit target. This is because the
    restart_block is held in the same memory allocation as the kernel stack.

    Moving the restart block to struct task_struct prevents this exploit by
    making the restart_block harder to locate.

    Note that there are other fields in thread_info that are also easy
    targets, at least on some architectures.

    It's also a decent simplification, since the restart code is more or less
    identical on all architectures.

  • d016bf7ec   mm: make FIRST_USER_ADDRESS unsigned long on all archs ... Browse Code »

    LKP has triggered a compiler warning after my recent patch "mm: account
    pmd page tables to the process":

    mm/mmap.c: In function 'exit_mmap':
    >> mm/mmap.c:2857:2: warning: right shift count >= width of type [enabled by default]

    The code:

    > 2857 WARN_ON(mm_nr_pmds(mm) >
    2858 round_up(FIRST_USER_ADDRESS, PUD_SIZE) >> PUD_SHIFT);

    In this, on tile, we have FIRST_USER_ADDRESS defined as 0. round_up() has
    the same type -- int. PUD_SHIFT.

    I think the best way to fix it is to define FIRST_USER_ADDRESS as unsigned
    long. On every arch for consistency.

    hexagon:defconfig fails to build in linux-next since commit 332fd7c4fef5
    ("genirq: Generic chip: Change irq_reg_{readl,writel} arguments").

    The primary build failure is

    arch/hexagon/include/asm/cacheflush.h: In function 'copy_to_user_page':
    arch/hexagon/include/asm/cacheflush.h:89:22: error: 'VM_EXEC' undeclared

    This is the result of including of from ,
    which is now necessary due to the use of readl and writel from irq.h.
    This causes recursive inclusions in hexagon code; cacheflush.h is included
    from mm.h prior to the definition of VM_EXEC.

    Fix the problem by moving copy_to_user_page from the hexagon include file to
    arch/hexagon/mm/cache.c, similar to other architectures. After this change,
    several redefinitions of readl and writel are reported. Those are caused
    by recursive inclusions of io.h and asm/cacheflush.h. Fix those problems by
    reducing the number of files included from those files. Also, it was necessary
    to stop including asm-generic/cacheflush.h from asm/cacheflush.h. Instead,
    functionality originally provided by asm-generic/cacheflush.h is now coded
    in asm/cacheflush.h directly.

    "A rather large update of timers, timekeeping & co

    - Core timekeeping code is year-2038 safe now for 32bit machines.
    Now we just need to fix all in kernel users and the gazillion of
    user space interfaces which rely on timespec/timeval :)

    - Better cache layout for the timekeeping internal data structures.

    - Proper nanosecond based interfaces for in kernel users.

    - Tree wide cleanup of code which wants nanoseconds but does hoops
    and loops to convert back and forth from timespecs. Some of it
    definitely belongs into the ugly code museum.

    - Consolidation of the timekeeping interface zoo.

    - A fast NMI safe accessor to clock monotonic for tracing. This is a
    long standing request to support correlated user/kernel space
    traces. With proper NTP frequency correction it's also suitable
    for correlation of traces accross separate machines.

    - Checkpoint/restart support for timerfd.

    - A few NOHZ[_FULL] improvements in the [hr]timer code.

    - Code move from kernel to kernel/time of all time* related code.

    - New clocksource/event drivers from the ARM universe. I'm really
    impressed that despite an architected timer in the newer chips SoC
    manufacturers insist on inventing new and differently broken SoC
    specific timers.

    [ Ed. "Impressed"? I don't think that word means what you think it means ]

    - Another round of code move from arch to drivers. Looks like most
    of the legacy mess in ARM regarding timers is sorted out except for
    a few obnoxious strongholds.

  • 24e4a8c3e   ktime: Kill non-scalar ktime_t implementation for 2038 ... Browse Code »
    2

    The non-scalar ktime_t implementation is basically a timespec
    which has to be changed to support dates past 2038 on 32bit
    systems.

    This patch removes the non-scalar ktime_t implementation, forcing
    the scalar s64 nanosecond version on all architectures.

    This may have additional performance overhead on some 32bit
    systems when converting between ktime_t and timespec structures,
    however the majority of 32bit systems (arm and i386) were already
    using scalar ktime_t, so no performance regressions will be seen
    on those platforms.

    On affected platforms, I'm open to finding optimizations, including
    avoiding converting to timespecs where possible.

    [ tglx: We can now cleanup the ktime_t.tv64 mess, but thats a
    different issue and we can throw a coccinelle script at it ]

  • 3a6bfbc91   arch, locking: Ciao arch_mutex_cpu_relax() ... Browse Code »
    13

    The arch_mutex_cpu_relax() function, introduced by 34b133f, is
    hacky and ugly. It was added a few years ago to address the fact
    that common cpu_relax() calls include yielding on s390, and thus
    impact the optimistic spinning functionality of mutexes. Nowadays
    we use this function well beyond mutexes: rwsem, qrwlock, mcs and
    lockref. Since the macro that defines the call is in the mutex header,
    any users must include mutex.h and the naming is misleading as well.

    This patch (i) renames the call to cpu_relax_lowlatency ("relax, but
    only if you can do it with very low latency") and (ii) defines it in
    each arch's asm/processor.h local header, just like for regular cpu_relax
    functions. On all archs, except s390, cpu_relax_lowlatency is simply cpu_relax,
    and thus we can take it out of mutex.h. While this can seem redundant,
    I believe it is a good choice as it allows us to move out arch specific
    logic from generic locking primitives and enables future(?) archs to
    transparently define it, similarly to System Z.

    If the renamed symbol is defined lib/iomap.c implements ioport_map and
    ioport_unmap and currently (nearly) all platforms define the port
    accessor functions outb/inb and friend unconditionally. So
    HAS_IOPORT_MAP is the better name for this.

    Consequently NO_IOPORT is renamed to NO_IOPORT_MAP.

    The motivation for this change is to reintroduce a symbol HAS_IOPORT
    that signals if outb/int et al are available. I will address that at
    least one merge window later though to keep surprises to a minimum and
    catch new introductions of (HAS|NO)_IOPORT.

    The changes in this commit were done using:

    $ git grep -l -E '(NO|HAS)_IOPORT' | xargs perl -p -i -e 's/\b((?:CONFIG_)?(?:NO|HAS)_IOPORT)\b/$1_MAP/'
