    staging: comedi: amplc_pc236: fix invalid register access during detach

    commit aaeb61a97b7159ebe30b18a422d04eeabfa8790b upstream.

    `pc236_detach()` is called by the comedi core if it attempted to attach
    a device and failed.  `pc236_detach()` calls `pc236_intr_disable()` if
    the comedi device private data pointer (`devpriv`) is non-null.  This
    test is insufficient as `pc236_intr_disable()` accesses hardware
    registers and the attach routine may have failed before it has saved
    their I/O base addresses.

    Fix it by checking `dev->iobase` is non-zero before calling
    `pc236_intr_disable()` as that means the I/O base addresses have been
    saved and the hardware registers can be accessed.  It also implies the
    comedi device private data pointer is valid, so there is no need to
    check it.

    commit 844ab6f993b1d32eb40512503d35ff6ad0c57030 upstream.

    Current logic finds enough space for direct mapping page tables from 0
    to end. Instead, we only need to find enough space to cover mr[0].start
    to mr[nr_range].end -- the range that is actually being mapped by
    init_memory_mapping()

    This is needed after 1bbbbe779aabe1f0768c2bf8f8c0a5583679b54a, to address

    mac80211: check if key has TKIP type before updating IV

    commit 4045f72bcf3c293c7c5932ef001742d8bb5ded76 upstream.

    This patch fix corruption which can manifest itself by following crash
    when switching on rfkill switch with rt2x00 driver:
    https://bugzilla.redhat.com/attachment.cgi?id=615362

    Pointer key->u.ccmp.tfm of group key get corrupted in:

    ieee80211_rx_h_michael_mic_verify():

            /* update IV in key information to be able to detect replays */
            rx->key->u.tkip.rx[rx->security_idx].iv32 = rx->tkip_iv32;
            rx->key->u.tkip.rx[rx->security_idx].iv16 = rx->tkip_iv16;

    because rt2x00 always set RX_FLAG_MMIC_STRIPPED, even if key is not TKIP.

    We already check type of the key in different path in
    ieee80211_rx_h_michael_mic_verify() function, so adding additional
    check here is reasonable.

    ARM: at91/i2c: change id to let i2c-gpio work

    commit 7840487cd6298f9f931103b558290d8d98d41c49 upstream.

    The i2c core driver will turn the platform device ID to busnum
    When using platfrom device ID as -1, it means dynamically assigned
    the busnum. When writing code, we need to make sure the busnum,
    and call i2c_register_board_info(int busnum, ...) to register device
    if using -1, we do not know the value of busnum

    In order to solve this issue, set the platform device ID as a fix number
    Here using 0 to match the busnum used in i2c_regsiter_board_info()

    xhci: Fix potential NULL ptr deref in command cancellation.

    commit 43a09f7fb01fa1e091416a2aa49b6c666458c1ee upstream.

    The command cancellation code doesn't check whether find_trb_seg()
    couldn't find the segment that contains the TRB to be canceled.  This
    could cause a NULL pointer deference later in the function when next_trb
    is called.  It's unlikely to happen unless something is wrong with the
    command ring pointers, so add some debugging in case it happens.

    This patch should be backported to stable kernels as old as 3.0, that
    contain the commit b63f4053cc8aa22a98e3f9a97845afe6c15d0a0d "xHCI:

    usb hub: send clear_tt_buffer_complete events when canceling TT clear work

    commit 3b6054da68f9b0d5ed6a7ed0f42a79e61904352c upstream.

    There is a race condition in the USB hub code with regard to handling
    TT clear requests that can get the HCD driver in a deadlock. Usually
    when an TT clear request is scheduled it will be executed immediately:

    However, if a suspend operation is triggered before hub_tt_work is
    scheduled, hub_quiesce will cancel the work without notifying the HCD
    driver:

    sysfs: sysfs_pathname/sysfs_add_one: Use strlcat() instead of strcat()

    commit 66081a72517a131430dcf986775f3268aafcb546 upstream.

    The warning check for duplicate sysfs entries can cause a buffer overflow
    when printing the warning, as strcat() doesn't check buffer sizes.
    Use strlcat() instead.

    Since strlcat() doesn't return a pointer to the passed buffer, unlike
    strcat(), I had to convert the nested concatenation in sysfs_add_one() to
    an admittedly more obscure comma operator construct, to avoid emitting code
    for the concatenation if CONFIG_BUG is disabled.

    SUNRPC: Prevent races in xs_abort_connection()

    commit 4bc1e68ed6a8b59be8a79eb719be515a55c7bc68 upstream.

    The call to xprt_disconnect_done() that is triggered by a successful
    connection reset will trigger another automatic wakeup of all tasks
    on the xprt->pending rpc_wait_queue. In particular it will cause an
    early wake up of the task that called xprt_connect().

    All we really want to do here is clear all the socket-specific state
    flags, so we split that functionality out of xs_sock_mark_closed()
    into a helper that can be called by xs_abort_connection()

    Now that we clear the connected flag when entering TCP_CLOSE_WAIT,

    SUNRPC: Get rid of the xs_error_report socket callback

    commit f878b657ce8e7d3673afe48110ec208a29e38c4a upstream.

    Chris Perl reports that we're seeing races between the wakeup call in
    xs_error_report and the connect attempts. Basically, Chris has shown
    that in certain circumstances, the call to xs_error_report causes the
    rpc_task that is responsible for reconnecting to wake up early, thus
    triggering a disconnect and retry.

    Since the sk->sk_error_report() calls in the socket layer are always
    followed by a tcp_done() in the cases where we care about waking up
    the rpc_tasks, just let the state_change callbacks take responsibility
    for those wake ups.

    ARM: 7559/1: smp: switch away from the idmap before updating init_mm.mm_count

    commit 5f40b909728ad784eb43aa309d3c4e9bdf050781 upstream.

    When booting a secondary CPU, the primary CPU hands two sets of page
    tables via the secondary_data struct:

    	(1) swapper_pg_dir: a normal, cacheable, shared (if SMP) mapping
    	    of the kernel image (i.e. the tables used by init_mm).

    	(2) idmap_pgd: an uncached mapping of the .idmap.text ELF
    	    section.

    The idmap is generally used when enabling and disabling the MMU, which
    includes early CPU boot. In this case, the secondary CPU switches to
    swapper as soon as it enters C code:

    	struct mm_struct *mm = &init_mm;
    	unsigned int cpu = smp_processor_id();

    	/*
    	 * All kernel threads share the same mm context; grab a
    	 * reference and switch to it.
    	 */
    	atomic_inc(&mm->mm_count);
    	current->active_mm = mm;
    	cpumask_set_cpu(cpu, mm_cpumask(mm));
    	cpu_switch_mm(mm->pgd, mm);

    This causes a problem on ARMv7, where the identity mapping is treated as
    strongly-ordered leading to architecturally UNPREDICTABLE behaviour of
    exclusive accesses, such as those used by atomic_inc.

    This patch re-orders the secondary_start_kernel function so that we
    switch to swapper before performing any exclusive accesses.

    genalloc: stop crashing the system when destroying a pool

    commit eedce141cd2dad8d0cefc5468ef41898949a7031 upstream.

    The genalloc code uses the bitmap API from include/linux/bitmap.h and
    lib/bitmap.c, which is based on long values.  Both bitmap_set from
    lib/bitmap.c and bitmap_set_ll, which is the lockless version from
    genalloc.c, use BITMAP_LAST_WORD_MASK to set the first bits in a long in
    the bitmap.

    That one uses (1 << bits) - 1, 0b111, if you are setting the first three
    bits.  This means that the API counts from the least significant bits
    (LSB from now on) to the MSB.  The LSB in the first long is bit 0, then.
    The same works for the lookup functions.

    The genalloc code uses longs for the bitmap, as it should.  In
    include/linux/genalloc.h, struct gen_pool_chunk has unsigned long
    bits[0] as its last member.  When allocating the struct, genalloc should
    reserve enough space for the bitmap.  This should be a proper number of
    longs that can fit the amount of bits in the bitmap.

    However, genalloc allocates an integer number of bytes that fit the
    amount of bits, but may not be an integer amount of longs.  9 bytes, for
    example, could be allocated for 70 bits.

    This is a problem in itself if the Least Significat Bit in a long is in
    the byte with the largest address, which happens in Big Endian machines.
    This means genalloc is not allocating the byte in which it will try to
    set or check for a bit.

    This may end up in memory corruption, where genalloc will try to set the
    bits it has not allocated.  In fact, genalloc may not set these bits
    because it may find them already set, because they were not zeroed since
    they were not allocated.  And that's what causes a BUG when
    gen_pool_destroy is called and check for any set bits.

    What really happens is that genalloc uses kmalloc_node with __GFP_ZERO
    on gen_pool_add_virt.  With SLAB and SLUB, this means the whole slab
    will be cleared, not only the requested bytes.  Since struct
    gen_pool_chunk has a size that is a multiple of 8, and slab sizes are
    multiples of 8, we get lucky and allocate and clear the right amount of
    bytes.

    Hower, this is not the case with SLOB or with older code that did memset
    after allocating instead of using __GFP_ZERO.

    So, a simple module as this (running 3.6.0), will cause a crash when
    rmmod'ed.

    fs/compat_ioctl.c: VIDEO_SET_SPU_PALETTE missing error check

    commit 12176503366885edd542389eed3aaf94be163fdb upstream.

    The compat ioctl for VIDEO_SET_SPU_PALETTE was missing an error check
    while converting ioctl arguments.  This could lead to leaking kernel
    stack contents into userspace.

    Patch extracted from existing fix in grsecurity.

    gen_init_cpio: avoid stack overflow when expanding

    commit 20f1de659b77364d55d4e7fad2ef657e7730323f upstream.

    Fix possible overflow of the buffer used for expanding environment
    variables when building file list.

    In the extremely unlikely case of an attacker having control over the
    environment variables visible to gen_init_cpio, control over the
    contents of the file gen_init_cpio parses, and gen_init_cpio was built
    without compiler hardening, the attacker can gain arbitrary execution
    control via a stack buffer overflow.

      $ cat usr/crash.list
      file foo ${BIG}${BIG}${BIG}${BIG}${BIG}${BIG} 0755 0 0
      $ BIG=$(perl -e 'print "A" x 4096;') ./usr/gen_init_cpio usr/crash.list
      *** buffer overflow detected ***: ./usr/gen_init_cpio terminated

    This also replaces the space-indenting with tabs.

    Patch based on existing fix extracted from grsecurity.
