f2527ec436 caif: Bugfix for socket priority, bindtodev and dbg channel.
Changes:
o Bugfix: SO_PRIORITY for SOL_SOCKET could not be handled
  in caif's setsockopt,  using the struct sock attribute priority instead.

o Bugfix: SO_BINDTODEVICE for SOL_SOCKET could not be handled
  in caif's setsockopt,  using the struct sock attribute ifindex instead.

o Wrong assert statement for RFM layer segmentation.

o CAIF Debug channels was not working over SPI, caif_payload_info
  containing padding info must be initialized.

o Check on pointer before dereferencing when unregister dev in caif_dev.c

df32cc193a net: check queue_index from sock is valid for device
In dev_pick_tx recompute the queue index if the value stored in the
socket is greater than or equal to the number of real queues for the
device.  The saved index in the sock structure is not guaranteed to
be appropriate for the egress device (this could happen on a route
change or in presence of tunnelling).  The result of the queue index
being bad would be to return a bogus queue (crash could prersumably
follow).

315daea948 USB: gadget: fix ethernet gadget crash in gether_setup
Crash is triggered by commit e6484930d7 ("net: allocate tx queues in

So now calling netif_stop_queue() before register_netdev causes an oops.
Move netif_stop_queue() after net device registration to fix crash.

d139ff0907 RDS: Let rds_message_alloc_sgs() return NULL
Even with the previous fix, we still are reading the iovecs once
to determine SGs needed, and then again later on. Preallocating
space for sg lists as part of rds_message seemed like a good idea
but it might be better to not do this. While working to redo that
code, this patch attempts to protect against userspace rewriting
the rds_iovec array between the first and second accesses.

The consequences of this would be either a too-small or too-large
sg list array. Too large is not an issue. This patch changes all
callers of message_alloc_sgs to handle running out of preallocated
sgs, and fail gracefully.

fc8162e3c0 RDS: Copy rds_iovecs into kernel memory instead of rereading from userspace
Change rds_rdma_pages to take a passed-in rds_iovec array instead
of doing copy_from_user itself.

Change rds_cmsg_rdma_args to copy rds_iovec array once only. This
eliminates the possibility of userspace changing it after our
sanity checks.

Implement stack-based storage for small numbers of iovecs, based
on net/socket.c, to save an alloc in the extremely common case.

Although this patch reduces iovec copies in cmsg_rdma_args to 1,
we still do another one in rds_rdma_extra_size. Getting rid of
that one will be trickier, so it'll be a separate patch.

1b1f693d7a net: fix rds_iovec page count overflow
As reported by Thomas Pollet, the rdma page counting can overflow.  We
get the rdma sizes in 64-bit unsigned entities, but then limit it to
UINT_MAX bytes and shift them down to pages (so with a possible "+1" for
an unaligned address).

So each individual page count fits comfortably in an 'unsigned int' (not
even close to overflowing into signed), but as they are added up, they
might end up resulting in a signed return value. Which would be wrong.

Catch the case of tot_pages turning negative, and return the appropriate
error code.

Section mismatch in reference from the variable pch_can_pcidev

The variable pch_can_pcidev references
the variable __devinitconst pch_pci_tbl

This is actually a false positive which is fixed by giving the offending
variable a whitelisted name, it's renamed to "pch_can_pci_driver".
This makes sense because the variable is of the type "struct pci_driver".

520efd1ace mac80211: fix failure to check kmalloc return value in key_key_read
I noticed two small issues in mac80211/debugfs_key.c::key_key_read while
reading through the code. Patch below.

The key_key_read() function returns ssize_t and the value that's actually
returned is the return value of simple_read_from_buffer() which also
returns ssize_t, so let's hold the return value in a ssize_t local
variable rather than a int one.

Also, memory is allocated dynamically with kmalloc() which can fail, but
the return value of kmalloc() is not checked, so we may end up operating
on a null pointer further on. So check for a NULL return and bail out with
-ENOMEM in that case.

731b203499 libertas: Fix sd8686 firmware reload
For the SD8686, we cannot rely on the scratch register to read the firmware
load status, because the same register is used for storing RX packet length.
Broaden the check to account for this.

The module can now be unloaded/reloaded successfully.

Based on the implementation from libertas_tf.

4fc4fbd1d9 ath9k: Fix incorrect access of rate flags in RC
The index variable to access the rate flags should be obtained from the
inner loop counter which corresponds to the rate table structure.This
fixes the invalid rate selection i.e when the supported basic rate is
invalid on a particular band and also the following warning message.
Thanks to Raj for finding this out.

Otherwise error indications from ipv6_find_hdr() won't be noticed.

This required making the protocol argument to extract_icmp6_fields()

This patch enables and disables the rx and tx bits in the MAC control reg
by using a single write operation.
This also solves a possible problem (spotted on SPEAr platforms) at 10Mbps
where two consecutive writes to a MAC control register can take more than
4 phy_clk cycles.
