Pull networking fixes from David Miller:
"This is what we usually expect at this stage of the game, lots of
little things, mostly in drivers. With the occasional 'oops didn't
mean to do that' kind of regressions in the core code."
1) Uninitialized data in __ip_vs_get_timeouts(), from Arnd Bergmann
2) Reject invalid ACK sequences in Fast Open sockets, from Jerry Chu.
3) Lost error code on return from _rtl_usb_receive(), from Christian
Lamparter.
4) Fix reset resume on USB rt2x00, from Stanislaw Gruszka.
5) Release resources on error in pch_gbe driver, from Veaceslav Falico.
6) Default hop limit not set correctly in ip6_template_metrics[], fix
from Li RongQing.
7) Gianfar PTP code requests wrong kind of resource during probe, fix
from Wei Yang.
8) Fix VHOST net driver on big-endian, from Michael S Tsirkin.
9) Mallenox driver bug fixes from Jack Morgenstein, Or Gerlitz, Moni
Shoua, Dotan Barak, and Uri Habusha.
10) usbnet leaks memory on TX path, fix from Hemant Kumar.
11) Use socket state test, rather than presence of FIN bit packet, to
determine FIONREAD/SIOCINQ value. Fix from Eric Dumazet.
12) Fix cxgb4 build failure, from Vipul Pandya.
13) Provide a SYN_DATA_ACKED state to complement SYN_FASTOPEN in socket
info dumps. From Yuchung Cheng.
14) Fix leak of security path in kfree_skb_partial(). Fix from Eric

These devices provide QMI and ethernet functionality via a standard CDC ethernet descriptor. But when driven by cdc_ether, the QMI functionality is unavailable because only cdc_ether can claim the USB interface.

Driver anchors the tx urbs and defers the urb submission if a transmit request comes when the interface is suspended. Anchoring urb increments the urb reference count. These deferred urbs are later accessed by calling usb_get_from_anchor() for submission during interface resume. usb_get_from_anchor() unanchors the urb but urb reference count remains same. This causes the urb reference count to remain non-zero after usb_free_urb() gets called and urb never gets freed. Hence call usb_put_urb() after anchoring the urb to properly balance the reference count for these deferred urbs. Also, unanchor these deferred urbs during disconnect, to free them up.

The delayed work function int_in_work() may call usb_reset_device() and thus, indirectly, the driver's pre_reset method. Trying to cancel the work synchronously in that situation would deadlock. Fix by avoiding cancel_work_sync() in the pre_reset method. If the reset was NOT initiated by int_in_work() this might cause int_in_work() to run after the post_reset method, with urb_int_in already resubmitted, so handle that case gracefully.

Like our other pen-and-touch products, the Cintiq 24HD touch needs data to be shared between its two sensors to facilitate proximity-based palm rejection. Unlike other tablets that report sensor data through separate interfaces of the same USB device, the Cintiq 24HD touch has separate USB devices that are connected to an internal USB hub. This patch makes it possible to designate the USB VID/PID of the other device so that the two may share data. To ensure we don't accidentally link to a sensor from a physically separate device (if several have been plugged in), we limit the search to siblings (i.e., devices directly connected to the same hub).

If one includes documentation for an external tool, it should be correct. This is not: 1. Overriding the input to rngd should typically be neither necessary nor desired. This is especially so since newer versions of rngd support a number of different *types* of sources. 2. The default kernel-exported device is called /dev/hwrng not /dev/hwrandom nor /dev/hw_random (both of which were used in the past; however, kernel and udev seem to have converged on /dev/hwrng.) Overall it is better if the documentation for rngd is kept with rngd rather than in a kernel Makefile. Signed-off-by: H.

Fix possible overflow of the buffer used for expanding environment

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.

'struct pid' is a "variable sized struct" - a header with an array of upids at the end. The size of the array depends on a level (depth) of pid namespaces. Now a level of pidns is not limited, so 'struct pid' can be more than one page. Looks reasonable, that it should be less than a page. MAX_PIS_NS_LEVEL is not calculated from PAGE_SIZE, because in this case it depends on architectures, config options and it will be reduced, if someone adds a new fields in struct pid or struct upid. I suggest to set MAX_PIS_NS_LEVEL = 32, because it saves ability to expand "struct pid" and it's more than enough for all known for me use-cases. When someone finds a reasonable use case, we can add a config option or a sysctl parameter. In addition it will reduce the effect of another problem, when we have many nested namespaces and the oldest one starts dying. zap_pid_ns_processe will be called for each namespace and find_vpid will be called for each process in a namespace. find_vpid will be called minimum max_level^2 / 2 times. The reason of that is that when we found a bit in pidmap, we can't determine this pidns is top for this process or it isn't. vpid is a heavy operation, so a fork bomb, which create many nested namespace, can make a system inaccessible for a long time. For example my system becomes inaccessible for a few minutes with 4000 processes.

The dw_dmac driver was originally developed for avr32 to be used with the Synopsys DesignWare AHB DMA controller. Starting from 2.6.38, access to the device's i/o memory was done with the little-endian readl/writel functions(1) This broke the driver for the avr32 platform, because it needs big (native) endian accessors. This patch makes the endianness configurable using 'DW_DMAC_BIG_ENDIAN_IO', which will default be true for AVR32 I submitted this patch before(2) but then waited for Andy to finish other changes to the same module(3).

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.
