2016-05-04net/mlx5: E-Switch, Replace vport spin lock with synchronize_irq()Mohamad Haj Yahia
Vport spin lock can be replaced with synchronize_irq() in the right place, this will remove the need of locking inside irq context. Locking in esw_enable_vport is not required since vport events are yet to be enabled, and at esw_disable_vport it is sufficient to synchronize_irq() to guarantee no further vport events handlers will be scheduled.

2016-05-04net/mlx5: Flow steering, Add vport ACL supportMohamad Haj Yahia
Update the relevant flow steering device structs and commands to support vport. Update the flow steering core API to receive vport number. Add ingress and egress ACL flow table name spaces. Add ACL flow table support: * ACL (Access Control List) flow table is a table that contains only allow/drop steering rules. * We have two types of ACL flow tables - ingress and egress. * ACLs handle traffic sent from/to E-Switch FDB table, Ingress refers to traffic sent from Vport to E-Switch and Egress refers to traffic sent from E-Switch to vport. * Ingress ACL flow table allow/drop rules is checked against traffic sent from VF. * Egress ACL flow table allow/drop rules is checked against traffic sent to VF.

2016-05-04ecryptfs: fix handling of directory openingAl Viro
First of all, trying to open them r/w is idiocy; it's guaranteed to fail. Moreover, assigning ->f_pos and assuming that everything will work is blatantly broken - try that with e.g. tmpfs as underlying layer and watch the fireworks. There may be a non-trivial amount of state associated with current IO position, well beyond the numeric offset. Using the single struct file associated with underlying inode is really not a good idea; we ought to open one for each ecryptfs directory struct file. Additionally, file_operations both for directories and non-directories are full of pointless methods; non-directories should *not* have ->iterate(), directories should not have ->flush(), ->fasync() and ->splice_read().

2016-05-04iwlwifi: mvm: don't override the rate with the AMSDU lenEmmanuel Grumbach
The TSO code creates A-MSDUs from a single large send. Each A-MSDU is an skb and skb->len doesn't include the number of bytes which need to be added for the headers being added (subframe header, TCP header, IP header, SNAP, padding). To be able to set the right value in the Tx command, we put the number of bytes added by those headers in driver_data in iwl_mvm_tx_tso and use this value in iwl_mvm_set_tx_cmd. The problem by setting this value in driver_data is that it overrides the ieee80211_tx_info. The bug manifested itself when we send P2P related frames in CCK since the rate in ieee80211_tx_info is zero-ed. This of course is a violation of the P2P specification. To fix this, copy the original ieee80211_tx_info to the stack and pass it to the functions which need it. Assign the number of bytes added by the headers to the driver_data inside the skb itself.

2016-05-04Merge branch 'tunnel-features-and-gso-partial'David S. Miller
Alexander Duyck says: ==================== Fix Tunnel features and enable GSO partial for several drivers This patch series is meant to allow us to get the best performance possible for Mellanox ConnectX-3/4 and Broadcom NetXtreme-C/E adapters in terms of VXLAN and GRE tunnels. The first 3 patches address issues I found in regards to GSO_PARTIAL and TSO_MANGLEID. The next 4 patches go through and enable GSO_PARTIAL for VXLAN tunnels that have an outer checksum enabled, and then enable IPv6 support where I can. One outstanding issue is that I wasn't able to get offloads working with outer IPv6 headers on mlx4. However that wasn't a feature that was enabled before so it isn't technically a regression, however I believe Engineers from Mellanox said they would look into it since they thought it should be supported. The last patch enables GSO_PARTIAL for VXLAN and GRE tunnels on the bnxt driver. One piece of feedback I received on the patch was that the hardware has globally set IPv6 UDP tunnels to always have the checksum field computed. I plan to work with Broadcom to get that addressed so that we only populate the checksum field if it was requested by the network stack. v2: Rebased patches off of latest changes to the mlx4/mlx5 drivers. Added bnxt driver patch as I received feedback on the RFC. v3: Moved 2 patches into series for net as they were generic fixes. Added patch to disable GSO partial if frame is less than 2x size of MSS There are outstanding issues as called out above that need to be addressed, however they were present before these patches so it isn't as if they introduce a regression. In addition gains can be easily seen so there should be no issue with applying the driver patches while the IPv6 mlx4_en and bnxt issues are being researched. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-04bnxt: Add support for segmentation of tunnels with outer checksumsAlexander Duyck
This patch assumes that the bnxt hardware will ignore existing IPv4/v6 header fields for length and checksum as well as the length and checksum fields for outer UDP and GRE headers. I have been told by Michael Chan that this is working. Though this might be somewhat redundant for IPv6 as they are forcing the checksum to be computed for all IPv6 frames that are offloaded. A follow-up patch may be necessary in order to fix this as it is essentially mangling the outer IPv6 headers to add a checksum where none was requested.

2016-05-04net/mlx5e: Fix IPv6 tunnel checksum offloadAlexander Duyck
The mlx5 driver exposes support for TSO6 but not IPv6 csum for hardware encapsulated tunnels. This leads to issues as it triggers warnings in skb_checksum_help as it ends up being called as we report supporting the segmentation but not the checksumming for IPv6 frames. This patch corrects that and drops 2 features that don't actually need to be supported in hw_enc_features since they are Rx features and don't actually impact anything by being present in hw_enc_features.

2016-05-04net/mlx4_en: Add support for inner IPv6 checksum offloads and TSOAlexander Duyck
>From what I can tell the ConnectX-3 will support an inner IPv6 checksum and segmentation offload, however it cannot support outer IPv6 headers. This assumption is based on the fact that I could see the checksum being offloaded for inner header on IPv4 tunnels, but not on IPv6 tunnels. For this reason I am adding the feature to the hw_enc_features and adding an extra check to the features_check call that will disable GSO and checksum offload in the case that the encapsulated frame has an outer IP version of that is not 4. The check in mlx4_en_features_check could be removed if at some point in the future a fix is found that allows the hardware to offload segmentation/checksum on tunnels with an outer IPv6 header.

2016-05-04gso: Only allow GSO_PARTIAL if we can checksum the inner protocolAlexander Duyck
This patch addresses a possible issue that can occur if we get into any odd corner cases where we support TSO for a given protocol but not the checksum or scatter-gather offload. There are few drivers floating around that setup their tunnels this way and by enforcing the checksum piece we can avoid mangling any frames.

2016-05-04gso: Do not perform partial GSO if number of partial segments is 1 or lessAlexander Duyck
In the event that the number of partial segments is equal to 1 we don't really need to perform partial segmentation offload. As such we should skip multiplying the MSS and instead just clear the partial_segs value since it will not provide any gain to advertise the frame as being GSO when it is a single frame.

2016-05-04gre: change gre_parse_header to return the header lengthJiri Benc
It's easier for gre_parse_header to return the header length instead of filing it into a parameter. That way, the callers that don't care about the header length can just check whether the returned value is lower than zero. In gre_err, the tunnel header must not be pulled. See commit b7f8fe251e46 ("gre: do not pull header in ICMP error processing") for details.

2016-05-04xen/evtchn: fix ring resize when binding new eventsJan Beulich
The copying of ring data was wrong for two cases: For a full ring nothing got copied at all (as in that case the canonicalized producer and consumer indexes are identical). And in case one or both of the canonicalized (after the resize) indexes would point into the second half of the buffer, the copied data ended up in the wrong (free) part of the new buffer. In both cases uninitialized data would get passed back to the caller. Fix this by simply copying the old ring contents twice: Once to the low half of the new buffer, and a second time to the high half. This addresses the inability to boot a HVM guest with 64 or more vCPUs. This regression was caused by 8620015499101090 (xen/evtchn: dynamically grow pending event channel ring).

2016-05-04intel_pstate: Fix intel_pstate_get()Rafael J. Wysocki
After commit 8fa520af5081 "intel_pstate: Remove freq calculation from intel_pstate_calc_busy()" intel_pstate_get() calls get_avg_frequency() to compute the average frequency, which is problematic for two reasons. First, intel_pstate_get() may be invoked before the driver reads the CPU feedback registers for the first time and if that happens, get_avg_frequency() will attempt to divide by zero. Second, the get_avg_frequency() call in intel_pstate_get() is racy with respect to intel_pstate_sample() and it may end up returning completely meaningless values for this reason. Moreover, after commit 7349ec0470b6 "intel_pstate: Move intel_pstate_calc_busy() into get_target_pstate_use_performance()" sample.core_pct_busy is never computed on Atom, but it is used in intel_pstate_adjust_busy_pstate() in that case too. To address those problems notice that if sample.core_pct_busy was used in the average frequency computation carried out by get_avg_frequency(), both the divide by zero problem and the race with respect to intel_pstate_sample() would be avoided. Accordingly, move the invocation of intel_pstate_calc_busy() from get_target_pstate_use_performance() to intel_pstate_update_util(), which also will take care of the uninitialized sample.core_pct_busy on Atom, and modify get_avg_frequency() to use sample.core_pct_busy as per the above.

2016-05-04mmc: omap_hsmmc: Use dma_request_chan() for requesting DMA channelPeter Ujfalusi
With the new dma_request_chan() the client driver does not need to look for the DMA resource and it does not need to pass filter_fn anymore. By switching to the new API the driver can now support deferred probing against DMA. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
2016-05-04mmc: sdhci-of-at91: add presets setupLudovic Desroches
The controller claims to support SDR104. In fact, it only supports a degraded SDR104 since the maximum frequency of the SD clock is 120 MHz instead of 208 MHz. The sdhci core is unaware of it and will compute a wrong clock divider. We can deal with this specific case by using presets.
