2017-04-21netvsc: Deal with rescinded channels correctlyK. Y. Srinivasan
We will not be able to send packets over a channel that has been rescinded. Make necessary adjustments so we can properly cleanup even when the channel is rescinded. This issue can be trigerred in the NIC hot-remove path. Signed-off-by: K. Y. Srinivasan <kys@microsoft.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Add some code to call disable_irq on all the vnic interface's irqs.

2017-04-21ibmvnic: Correct crq and resource releasingNathan Fontenot
We should not be releasing the crq's when calling close for the adapter, these need to remain open to facilitate operations such as updating the mac address. The crq's should be released in the adpaters remove routine. Additionally, we need to call release_reources from remove.

2017-04-21gso: Validate assumption of frag_list segementationIlan Tayari
Commit 07b26c9454a2 ("gso: Support partial splitting at the frag_list pointer") assumes that all SKBs in a frag_list (except maybe the last one) contain the same amount of GSO payload. This assumption is not always correct, resulting in the following warning message in the log: skb_segment: too many frags For example, mlx5 driver in Striding RQ mode creates some RX SKBs with one frag, and some with 2 frags. After GRO, the frag_list SKBs end up having different amounts of payload. If this frag_list SKB is then forwarded, the aforementioned assumption is violated. Validate the assumption, and fall back to software GSO if it not true.

Constants used for tuning are generally a bad idea, especially as hardware changes over time. Replace the constant 2 jiffies with sysctl variable netdev_budget_usecs to enable sysadmins to tune the softirq processing. Also document the variable. For example, a very fast machine might tune this to 1000 microseconds, while my regression testing 486DX-25 needs it to be 4000 microseconds on a nearly idle network to prevent time_squeeze from being incremented.

This feature allows the administrator to set an fwmark for packets traversing a tunnel. This allows the use of independent routing tables for tunneled packets without the use of iptables. There is no concept of per-packet routing decisions through IPv4 tunnels, so this implementation does not need to work with per-packet route lookups as the v6 implementation may (with IP6_TNL_F_USE_ORIG_FWMARK). Further, since the v4 tunnel ioctls share datastructures (which can not be trivially modified) with the kernel's internal tunnel configuration structures, the mark attribute must be stored in the tunnel structure itself and passed as a parameter when creating or changing tunnel attributes.

2017-04-21spi: spi-ti-qspi: Use bounce buffer if read buffer is not DMA'bleVignesh R
Flash filesystems like JFFS2, UBIFS and MTD block layer can provide vmalloc'd or kmap'd buffers that cannot be mapped using dma_map_sg() and can potentially be in memory region above 32bit addressable region(ie buffers belonging to memory region backed by LPAE) of DMA, implement spi_flash_can_dma() interface to inform SPI core not to map such buffers. When buffers are not mapped for DMA, then use a pre allocated bounce buffer(64K = typical flash erase sector size) to read from flash and then do a copy to actual destination buffer. This is approach is much faster than using memcpy using CPU and also reduces CPU load. With this patch, UBIFS read speed is ~18MB/s and CPU utilization <20% on DRA74 Rev H EVM. Performance degradation is negligible when compared with non bounce buffer case while using UBIFS. Signed-off-by: Vignesh R <vigneshr@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2017-04-21ASoC: Intel: Skylake: Uninitialized variable in probe_codec()Dan Carpenter
My static checker complains that if snd_hdac_bus_get_response() returns -EIO then "res" is uninitialized. Fix this by initializing it to -1 so that the error is handled correctly.

In case of an error, the properties reported to user are zeroed out, so no need for a return value. Signed-off-by: Noa Osherovich <noaos@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>
2017-04-21ASoC: rsnd: Fix possible NULL pointer dereferenceMarek Vasut
25165f79adc76b812bfb4d8f2ab120aafb28d0e6 ("ASoC: rsnd: enable clock-frequency for both 44.1kHz/48kHz") supports both 44.1kHz/48kHz clock-frequency settings for ADG which will be used for AUDIO_OLKOUTn. But some board doesn't need it, thus, it is not mandatory. But, above patch didn't care about the case of "clock-frequency" DT property was not present. This patch ignores ADG settings if AUDIO_OLKOUTn was not used.

2017-04-21IB/mlx5: Set correct SL in completion for RoCEMoni Shoua
There is a difference when parsing a completion entry between Ethernet and IB ports. When link layer is Ethernet the bits describe the type of L3 header in the packet. In the case when link layer is Ethernet and VLAN header is present the value of SL is equal to the 3 UP bits in the VLAN header. If VLAN header is not present then the SL is undefined and consumer of the completion should check if IB_WC_WITH_VLAN is set. While that, this patch also fills the vlan_id field in the completion if present.

2017-04-21IB/cma: Send MRA for reply messagesMoni Shoua
Current implementation of RDMA_CM sends MRA (Message Receipt Acknowledgment) only for request messages but not for response messages. As a result, a slow active side of the connection may send a ready-to-use message to the passive side in a delay that is too long for the passive side to wait for. This patch adds a call to ib_send_cm_mra() upon receiving a response message and by this tells the other side to modify the service timeout to a bigger value, 16 times than before. As in the request case, MRA for reply will be sent only if a duplicate response has arrived.
