2019-09-14KVM: X86: Use IPI shorthands in kvm guest when supportWanpeng Li
IPI shorthand is supported now by linux apic/x2apic driver, switch to IPI shorthand for all excluding self and all including self destination shorthand in kvm guest, to avoid splitting the target mask into several PV IPI hypercalls. This patch removes the kvm_send_ipi_all() and kvm_send_ipi_allbutself() since the callers in APIC codes have already taken care of apic_use_ipi_shorthand and fallback to ->send_IPI_mask and ->send_IPI_mask_allbutself if it is false.

2019-09-13md: add feature flag MD_FEATURE_RAID0_LAYOUTNeilBrown
Due to a bug introduced in Linux 3.14 we cannot determine the correctly layout for a multi-zone RAID0 array - there are two possibilities. It is possible to tell the kernel which to chose using a module parameter, but this can be clumsy to use. It would be best if the choice were recorded in the metadata. So add a feature flag for this purpose. If it is set, then the 'layout' field of the superblock is used to determine which layout to use. If this flag is not set, then mddev->layout gets set to -1, which causes the module parameter to be required.

2019-09-13md/raid0: avoid RAID0 data corruption due to layout confusion.NeilBrown
If the drives in a RAID0 are not all the same size, the array is divided into zones. The first zone covers all drives, to the size of the smallest. The second zone covers all drives larger than the smallest, up to the size of the second smallest - etc. A change in Linux 3.14 unintentionally changed the layout for the second and subsequent zones. All the correct data is still stored, but each chunk may be assigned to a different device than in pre-3.14 kernels. This can lead to data corruption. It is not possible to determine what layout to use - it depends which kernel the data was written by. So we add a module parameter to allow the old (0) or new (1) layout to be specified, and refused to assemble an affected array if that parameter is not set.

2019-09-13raid5: don't increment read_errors on EILSEQ returnNigel Croxon
While MD continues to count read errors returned by the lower layer. If those errors are -EILSEQ, instead of -EIO, it should NOT increase the read_errors count. When RAID6 is set up on dm-integrity target that detects massive corruption, the leg will be ejected from the array. Even if the issue is correctable with a sector re-write and the array has necessary redundancy to correct it. The leg is ejected because it runs up the rdev->read_errors beyond conf->max_nr_stripes. The return status in dm-drypt when there is a data integrity error is -EILSEQ (BLK_STS_PROTECTION). Signed-off-by: Nigel Croxon <ncroxon@redhat.com> Signed-off-by: Song Liu <songliubraving@fb.com>
2019-09-13cdc_ether: fix rndis support for Mediatek based smartphonesBjørn Mork
A Mediatek based smartphone owner reports problems with USB tethering in Linux. The verbose USB listing shows a rndis_host interface pair (e0/01/03 + 10/00/00), but the driver fails to bind with [ 355.960428] usb 1-4: bad CDC descriptors The problem is a failsafe test intended to filter out ACM serial functions using the same 02/02/ff class/subclass/protocol as RNDIS. The serial functions are recognized by their non-zero bmCapabilities. No RNDIS function with non-zero bmCapabilities were known at the time this failsafe was added. But it turns out that some Wireless class RNDIS functions are using the bmCapabilities field. These functions are uniquely identified as RNDIS by their class/subclass/protocol, so the failing test can safely be disabled. The same applies to the two types of Misc class RNDIS functions. Applying the failsafe to Communication class functions only retains the original functionality, and fixes the problem for the Mediatek based smartphone. Tow examples of CDC functional descriptors with non-zero bmCapabilities from Wireless class RNDIS functions are: 0e8d:000a Mediatek Crosscall Spider X5 3G Phone CDC Header: bcdCDC 1.10 CDC ACM: bmCapabilities 0x0f connection notifications sends break line coding and serial state get/set/clear comm features CDC Union: bMasterInterface 0 bSlaveInterface 1 CDC Call Management: bmCapabilities 0x03 call management use DataInterface bDataInterface 1 and 19d2:1023 ZTE K4201-z CDC Header: bcdCDC 1.10 CDC ACM: bmCapabilities 0x02 line coding and serial state CDC Call Management: bmCapabilities 0x03 call management use DataInterface bDataInterface 1 CDC Union: bMasterInterface 0 bSlaveInterface 1 The Mediatek example is believed to apply to most smartphones with Mediatek firmware.

Now two callers are sctp_get_port and sctp_do_bind, they actually assumend a casted to an int was the same as a pointer casted to a long, and they don't save the return value just check whether it is zero or non-zero, so it would better change return type from long to int for sctp_get_port_local.

To perform DPK, the parameter table should also be updated. And the table will be applied when device is powered on. Then DPK will reference the values to calibrate.

Add support for doing IQK in firmware Ideally the RF component's I/Q vectors should be orthogonal, but usually they are not. So we need to calibrate for the RF components, ex. PA/LNA, ADC/DAC. And if the I/Q vectors are more orthogonal, the mixed signal will have less deviation. This helps with those rates with higher modulation (MCS8-9), because they have more strict EVM/SNR requirement. Also the better of the quality of the signal, the longer it can propagate, and the better throughput performance we can get.

That will be changed in the next patch. Several places where checkpatch.pl complains about a space after a cast are fixed.

2019-09-13rtlwifi: rtl8723be: Replace local bit manipulation macrosLarry Finger
This driver uses a set of local macros to manipulate the RX and TX descriptors, which are all little-endian quantities. These macros are replaced by the bitfield macros le32p_replace_bits() and le32_get_bits(). In several places, the macros operated on an entire 32-bit word. In these cases, a direct read or replacement is used. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2019-09-13rtlwifi: rtl8723ae: Convert inline routines to little-endian wordsLarry Finger
In this step, the read/write routines for the descriptors are converted to use __le32 quantities, thus a lot of casts can be removed. Callback routines still use the 8-bit arrays, but these are changed within the specified routine. The macro that cleared a descriptor has now been converted into an inline routine.

Some controllers allow for a one-shot output pulse, in contrast to periodic output. Now that we have extensible versions of our IOCTLs, we can finally make use of the 'flags' field to pass a bit telling driver that if we want one-shot pulse output.

The current version of the IOCTL have a small problem which prevents us from extending the API by making use of reserved fields. In these new IOCTLs, we are now making sure that flags and rsv fields are zero which will allow us to extend the API in the future.

2019-09-13ixgbevf: Fix secpath usage for IPsec Tx offloadJeff Kirsher
Port the same fix for ixgbe to ixgbevf. The ixgbevf driver currently does IPsec Tx offloading based on an existing secpath. However, the secpath can also come from the Rx side, in this case it is misinterpreted for Tx offload and the packets are dropped with a "bad sa_idx" error. Fix this by using the xfrm_offload() function to test for Tx offload.

Paul updates the way the driver version is stored in the driver so that we can pass the driver version to the firmware. Passing of the driver version to the firmware is needed for the DDP package to ensure we have the appropriate support in the driver for the features in the package. Lukasz fixes how the firmware version is stored to align with how the firmware stores its own version. Also extended the log message to display additional useful information such as NVM version, API patch information and firmware build hash. Tony adds the needed driver support to check, load and store the DDP package. Also add support for the ability to load DDP packages intended for specific hardware devices, as well as what to do when loading of the DDP package fails to load. ==================== Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2019-09-11 This series contains updates to i40e, ixgbe/vf and iavf. Wenwen Wang fixes a potential memory leak where 3 allocated variables are not properly cleaned up on failure for ixgbe. Stefan Assmann fixes a potential kernel panic found when repeatedly spawning and destroying VFs in i40e when a NULL pointer is dereferenced due to a race condition. Fixed up the i40e driver to clear the __I40E_VIRTCHNL_OP_PENDING bit before returning after an invalid minimum transmit rate is requested. Updates the iavf driver to only apply the MAC address change when the PF ACK's the requested change. Tonghao Zhang updates ixgbe to use the skb_get_queue_mapping() API call instead of the driver accessing the queue mapping directly. Jake updates i40e to use ktime_get_real_ts64() instead of ktime_to_timespec64(). Removes the define for bit 0x0001 for cloud filters, since it is a reserved bit and not a valid type. Also added code comments to clearly state which bits are reserved and should not be used or defined for cloud filter adminq command. Clarify the macros used to specify the cloud filter fields are individual bits, so use the BIT() macro. Aleksandr fixes up the print_link_message() to include the "negotiated" FEC status for i40e. Czeslaw also adds additional log message for devices without FEC in the print_link_message() for i40e. Colin Ian King reduces the object code size by making the array API static constant. Magnus fixes a potential receive buffer starvation issue for AF_XDP by kicking the NAPI context of any queue with an attached AF_XDP zero-copy socket. v2: Removed patch 11 from the original series (Alex Duyck's ITR fix), so that it can be sent to the net tree. ==================== Signed-off-by: David S.
