2014-11-26net/mlx4_core: Limit count field to 24 bits in qp_alloc_resJack Morgenstein
Some VF drivers use the upper byte of "param1" (the qp count field) in mlx4_qp_reserve_range() to pass flags which are used to optimize the range allocation. Under the current code, if any of these flags are set, the 32-bit count field yields a count greater than 2^24, which is out of range, and this VF fails. As these flags represent a "best-effort" allocation hint anyway, they may safely be ignored. Therefore, the PF driver may simply mask out the bits.

Add mem_val debugfs file for dumping the firmware (target) memory and also for writing to the memory. The firmware memory is accessed through one file which uses position of the file as the firmware memory address. For example, with dd use skip parameter for the address. Beucase target memory width is 32 bits it's strongly recommended to use blocksize divisable with 4 when using this interface. For example, when using dd use bs=4 to set the block size to 4 and remember to divide both count and skip values with four.

When static keys are used in shared WEP, when a station is associated, message 3 is sent with an encrypted payload. But, for subsequent authentications that are triggered without a deauth, the auth frame is decrypted by the HW. To handle this, check if the WEP keys have already been set for the peer and if so, mark the frame as decrypted. This scenario can happen when a station changes its default TX key and initiates a new authentication sequence.

2014-11-25net: Hyper-V: Deletion of an unnecessary check before the function call "vfree"Markus Elfring
The vfree() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

2014-11-25tg3: fix ring init when there are more TX than RX channelsThadeu Lima de Souza Cascardo
If TX channels are set to 4 and RX channels are set to less than 4, using ethtool -L, the driver will try to initialize more RX channels than it has allocated, causing an oops. This fix only initializes the RX ring if it has been allocated. Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-11-25rtlwifi: Change order in device startupLarry Finger
The existing order of steps when starting the PCI devices works for 2.4G devices, but fails to initialize the 5G section of the RTL8821AE hardware. This patch is needed to fix the regression reported in Bug #88811 (https://bugzilla.kernel.org/show_bug.cgi?id=88811).

2014-11-25vxlan: Fix boolean flip in VXLAN_F_UDP_ZERO_CSUM6_[TX|RX]Alexander Duyck
In "vxlan: Call udp_sock_create" there was a logic error that resulted in the default for IPv6 VXLAN tunnels going from using checksums to not using checksums. Since there is currently no support in iproute2 for setting these values it means that a kernel after the change cannot talk over a IPv6 VXLAN tunnel to a kernel prior the change.
