  • Currently svc_sock_names calls svc_close_xprt on a svc_sock to
    which it does not own a reference.
    As soon as svc_close_xprt sets XPT_CLOSE, the socket could be
    freed by a separate thread (though this is a very unlikely race).

    It is safer to hold a reference while calling svc_close_xprt.

  • The xpt_pool field is only used for reporting BUGs.
    And it isn't used correctly.

    In particular, when it is cleared in svc_xprt_received before
    XPT_BUSY is cleared, there is no guarantee that either the
    compiler or the CPU might not re-order to two assignments, just
    setting xpt_pool to NULL after XPT_BUSY is cleared.

    If a different cpu were running svc_xprt_enqueue at this moment,
    it might see XPT_BUSY clear and then xpt_pool non-NULL, and
    so BUG.

    This could be fixed by calling
    smp_mb__before_clear_bit()
    before the clear_bit. However as xpt_pool isn't really used,
    it seems safest to simply remove xpt_pool.

    Another alternate would be to change the clear_bit to
    clear_bit_unlock, and the test_and_set_bit to test_and_set_bit_lock.

  • Instead of failing to find client entries which don't match the
    minorversion, we should be finding them, then either erroring out or
    expiring them as appropriate.

    This also fixes a problem which would cause the 4.1 server to fail to
    recognize clients after a second reboot.

  • The install_special_mapping routine (used, for example, to setup the
    vdso) skips the security check before insert_vm_struct, allowing a local
    attacker to bypass the mmap_min_addr security restriction by limiting
    the available pages for special mappings.

    bprm_mm_init() also skips the check, and although I don't think this can
    be used to bypass any restrictions, I don't see any reason not to have
    the security check.

  • This gets caught by the new sanity check code. Instead of the slash use a
    different symbol. This was originally found by Major Lee who proposed a
    rather more complex patch which changed the name according to the chip
    type.

    On the basis that we are in a late -rc and making Linus grumpy isn't always
    a good idea (however fun) this is a simple alternative.

  • Cache ownership must be acquired by reading/writing data from the
    cache line to make cache operation have the desired effect on the
    SMP MPCore CPU. However, the ownership is never acquired in the
    v6_dma_inv_range function when cleaning the first line and
    flushing the last one, in case the address is not aligned
    to D_CACHE_LINE_SIZE boundary.
    Fix this by reading/writing data if needed, before performing
    cache operations.
    While at it, fix v6_dma_flush_range to prevent RWFO outside
    the buffer.

  • Because the nwfpe support is unlikely to be used on new platforms
    and requires CONFIG_OABI_COMPAT, which is not generally used with
    ARMv7+, we shouldn't expect to build nwfpe support into a Thumb-2
    kernel.

    At present, nwfpe contains assembly code which isn't Thumb-2
    compatible, and for now it doesn't appear useful to port this
    code.

    All ARMv7-A/R platforms necessarily have VFPv3 hardware floating-
    point natively, making emulation unnecessary.

  • This makes sense, because Thumb-2 code can't execute on plain
    ARMv6 processors.

    This will avoid accidentally configuring a broken kernel where the
    config otherwise would allow multiple architecture versions to
    coexist in the same kernel.

    Not adding !CPU_V5 etc., because the chance of anyone trying to
    put v5 and v7 in the same kernel is low, and I'm not aware of
    any mach which can do this. These could be added later if it
    matters.

    Note that the rules may need to be refined if support for the
    ARM1156J(F)-S processor is later added to the kernel, since this
    processor supports the rare ARMv6T2 extensions, which add support
    for Thumb-2 and a few other ARMv7 features.
