2020-05-29spi: spi-fsl-dspi: fix native data copyAngelo Dureghello
ColdFire is a big-endian cpu with a big-endian dspi hw module, so, it uses native access, but memcpy breaks the endianness. So, if i understand properly, by native copy we would mean be(cpu)->be(dspi) or le(cpu)->le(dspi) accesses, so my fix shouldn't break anything, but i couldn't test it on LS family, so every test is really appreciated.

kobject_init_and_add() takes reference even when it fails. If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object. Thus, replace kfree() by kobject_put() to fix this issue. Previous commit "b8eb718348b8" fixed a similar problem.

This is because when the conversion of the MSCC PHY driver to use the shared PHY package helpers was done, the base address retrieval and the base PHY read and write helpers in the driver were modified. In particular, the base address retrieval logic was moved from the config_init to the probe. But the vsc8574_probe was forgotten. This patch fixes it.

Jesper Dangaard Brouer fixes up code comments in i40e_xsk.c Xie XiuQi, from Huawei, fixes a signed-integer-overflow warning ixgbe driver. Jason Yan, from Huawei, converts '==' expression to bool to resolve warnings, also fixed a warning for assigning 0/1 to a bool variable in the ixgbe driver. Converts functions that always return 0 to void in the igb and i40e drivers. YueHaibing, from Hauwei, cleans up dead code in ixgbe driver. Sasha cleans up more dead code which is not used in the igc driver. Added receive error counter to reflect the total number of non-filtered packets received with errors. Fixed a register define name to properly reflect the register address being used. Andre updates the igc driver to reject NFC rules that have multiple matches, which is not supported in i225 devices. Updates the total number of NFC rules supported and added a code comment to explain what is supported. Punit Agrawal, from Toshiba, relaxes the condition to trigger a reset for ME, which was leading to inconsistency between the state of the hardware as expected by the driver in e1000e.

2020-05-29RDMA/core: Introduce shared CQ pool APIYamin Friedman
Allow a ULP to ask the core to provide a completion queue based on a least-used search on a per-device CQ pools. The device CQ pools grow in a lazy fashion when more CQs are requested. This feature reduces the amount of interrupts when using many QPs. Using shared CQs allows for more effcient completion handling. It also reduces the amount of overhead needed for CQ contexts. Test setup: Intel(R) Xeon(R) Platinum 8176M CPU @ 2.10GHz servers. Running NVMeoF 4KB read IOs over ConnectX-5EX across Spectrum switch. TX-depth = 32. The patch was applied in the nvme driver on both the target and initiator. Four controllers are accessed from each core. In the current test case we have exposed sixteen NVMe namespaces using four different subsystems (four namespaces per subsystem) from one NVM port. Each controller allocated X queues (RDMA QPs) and attached to Y CQs. Before this series we had X == Y, i.e for four controllers we've created total of 4X QPs and 4X CQs. In the shared case, we've created 4X QPs and only X CQs which means that we have four controllers that share a completion queue per core. Until fourteen cores there is no significant change in performance and the number of interrupts per second is less than a million in the current case. ================================================== |Cores|Current KIOPs |Shared KIOPs |improvement| |-----|---------------|--------------|-----------| |14 |2332 |2723 |16.7% | |-----|---------------|--------------|-----------| |20 |2086 |2712 |30% | |-----|---------------|--------------|-----------| |28 |1971 |2669 |35.4% | |================================================= |Cores|Current avg lat|Shared avg lat|improvement| |-----|---------------|--------------|-----------| |14 |767us |657us |14.3% | |-----|---------------|--------------|-----------| |20 |1225us |943us |23% | |-----|---------------|--------------|-----------| |28 |1816us |1341us |26.1% | ======================================================== |Cores|Current interrupts|Shared interrupts|improvement| |-----|------------------|-----------------|-----------| |14 |1.6M/sec |0.4M/sec |72% | |-----|------------------|-----------------|-----------| |20 |2.8M/sec |0.6M/sec |72.4% | |-----|------------------|-----------------|-----------| |28 |2.9M/sec |0.8M/sec |63.4% | ==================================================================== |Cores|Current 99.99th PCTL lat|Shared 99.99th PCTL lat|improvement| |-----|------------------------|-----------------------|-----------| |14 |67ms |6ms |90.9% | |-----|------------------------|-----------------------|-----------| |20 |5ms |6ms |-10% | |-----|------------------------|-----------------------|-----------| |28 |8.7ms |6ms |25.9% | |=================================================================== Performance improvement with sixteen disks (sixteen CQs per core) is comparable.

2020-05-29RDMA/srpt: Reduce max_recv_sge to 1Bart Van Assche
Since srpt_post_recv() always sets num_sge to 1, reduce the max_recv_sge parameter that is used at queue pair allocation time to 1.

2020-05-29RDMA/srpt: Make debug output more detailedBart Van Assche
Since the session name by itself is not sufficient to uniquely identify a queue pair, include the queue pair number. Show the ASCII channel state name instead of the numeric value. This change makes the ib_srpt debug output more consistent.

2020-05-29null_blk: force complete for timeout requestDongli Zhang
The commit 7b11eab041da ("blk-mq: blk-mq: provide forced completion method") exports new API to force a request to complete without error injection. There should be no error injection when completing a request by timeout handler. Otherwise, the below would hang because timeout handler is failed. echo 100 > /sys/kernel/debug/fail_io_timeout/probability echo 1000 > /sys/kernel/debug/fail_io_timeout/times echo 1 > /sys/block/nullb0/io-timeout-fail dd if=/dev/zero of=/dev/nullb0 bs=512 count=1 oflag=direct With this patch, the timeout handler is able to complete the IO.

2020-05-29mwifiex: Add support for NL80211_ATTR_MAX_AP_ASSOC_STAPali Rohár
SD8997 firmware sends TLV_TYPE_MAX_CONN with struct hw_spec_max_conn to inform kernel about maximum number of p2p connections and stations in AP mode. During initialization of SD8997 wifi chip kernel prints warning: mwifiex_sdio mmc0:0001:1: Unknown GET_HW_SPEC TLV type: 0x217 This patch adds support for parsing TLV_TYPE_MAX_CONN (0x217) and sets appropriate cfg80211 member 'max_ap_assoc_sta' from retrieved structure. It allows userspace to retrieve NL80211_ATTR_MAX_AP_ASSOC_STA attribute.

2020-05-29airo: Fix read overflows sending packetsDan Carpenter
The problem is that we always copy a minimum of ETH_ZLEN (60) bytes from skb->data even when skb->len is less than ETH_ZLEN so it leads to a read overflow. The fix is to pad skb->data to at least ETH_ZLEN bytes.
