2019-09-10nfp: honor FW reset and loading policiesDirk van der Merwe
The firmware reset and loading policies can be controlled with the combination of three hwinfo keys, 'abi_drv_reset', 'abi_drv_load_ifc' and 'app_fw_from_flash'. 'app_fw_from_flash' defines which firmware should take precedence, 'Disk', 'Flash' or the 'Preferred' firmware. When 'Preferred' is selected, the management firmware makes the decision on which firmware will be loaded by comparing versions of the flash firmware and the host supplied firmware. 'abi_drv_reset' defines when the driver should reset the firmware when the driver is probed, either 'Disk' if firmware was found on disk, 'Always' reset or 'Never' reset. Note that the device is always reset on driver unload if firmware was loaded when the driver was probed. 'abi_drv_load_ifc' defines a list of PF devices allowed to load FW on the device. Furthermore, we limit the cases to where the driver will unload firmware again when the driver is removed to only when firmware was loaded by the driver and only if this particular device was the only one that could have loaded firmware. This is needed to avoid firmware being removed while in use on multi-host platforms.

2019-09-10nfp: nsp: add support for optional hwinfo lookupDirk van der Merwe
There are cases where we want to read a hwinfo entry from the NFP, and if it doesn't exist, use a default value instead. To support this, we must silence warning/error messages when the hwinfo entry doesn't exist since this is a valid use case. The NSP command structure provides the ability to silence command errors, in which case the caller should log any command errors appropriately. Protocol errors are unaffected by this.

2019-09-10ARM: 8906/1: drivers/amba: add reset control to amba bus probeDINH L NGUYEN
The primecell controller on some SoCs, i.e. SoCFPGA, is held in reset by default. Until recently, the DMA controller was brought out of reset by the bootloader(i.e. U-Boot). But a recent change in U-Boot, the peripherals that are not used are held in reset and are left to Linux to bring them out of reset. Add a mechanism for getting the reset property and de-assert the primecell module from reset if found. This is a not a hard fail if the reset property is not present in the device tree node, so the driver will continue to probe. Because there are different variants of the controller that may have multiple reset signals, the code will find all reset(s) specified and de-assert them.

The hole msdu's PN check will fail and the hole msdu will be dropped. PN check fail example: Sequence number PN number PN check status 3814 6101 success 3815 6102 success 3816 6103 success 3818 6105 success 3819 6106 success 3820 6107 success 3817 6104 fail The correct logic is reorder the msdu list and then do PN check. ieee80211_rx_reorder_ampdu of mac80211 will do the reorer logic and then do PN check in ieee80211_rx_h_decrypt of mac80211. example after reorder: Sequence number PN number PN check status 3814 6101 success 3815 6102 success 3816 6103 success 3817 6104 success 3818 6105 success 3819 6106 success 3820 6107 success Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWP-1.

We should only try to execute fallback quirks handling when previous call returned -ENOENT, and not when we did not get -EPROBE_DEFER. The other errors should be treated as hard errors: we did find the GPIO description, but for some reason we failed to handle it properly. The fallbacks should only be executed when previous handlers returned -ENOENT, which means the mapping/description was not found. Also let's remove the explicit deferral handling when iterating through GPIO suffixes: it is not needed anymore as we will not be calling fallbacks for anything but -ENOENT.

2019-09-10spi: bcm2835: Work around DONE bit erratumLukas Wunner
Commit 3bd7f6589f67 ("spi: bcm2835: Overcome sglist entry length limitation") amended the BCM2835 SPI driver with support for DMA transfers whose buffers are not aligned to 4 bytes and require more than one sglist entry. When testing this feature with upcoming commits to speed up TX-only and RX-only transfers, I noticed that SPI transmission sometimes breaks. A function introduced by the commit, bcm2835_spi_transfer_prologue(), performs one or two PIO transmissions as a prologue to the actual DMA transmission. It turns out that the breakage goes away if the DONE bit in the CS register is set when ending such a PIO transmission. The DONE bit signifies emptiness of the TX FIFO. According to the spec, the bit is of type RO, so writing it should never have any effect. Perhaps the spec is wrong and the bit is actually of type RW1C. E.g. the I2C controller on the BCM2835 does have an RW1C DONE bit which needs to be cleared by the driver. Another, possibly more likely explanation is that it's a hardware erratum since the issue does not occur consistently. Either way, amend bcm2835_spi_transfer_prologue() to always write the DONE bit. Usually a transmission is ended by bcm2835_spi_reset_hw(). If the transmission was successful, the TX FIFO is empty and thus the DONE bit is set when bcm2835_spi_reset_hw() reads the CS register. The bit is then written back to the register, so we happen to do the right thing. However if DONE is not set, e.g. because transmission is aborted with a non-empty TX FIFO, the bit won't be written by bcm2835_spi_reset_hw() and it seems possible that transmission might subsequently break. To be on the safe side, likewise amend bcm2835_spi_reset_hw() to always write the bit.

2019-09-09ixgbe: sync the first fragment unconditionallyFiro Yang
In Xen environment, if Xen-swiotlb is enabled, ixgbe driver could possibly allocate a page, DMA memory buffer, for the first fragment which is not suitable for Xen-swiotlb to do DMA operations. Xen-swiotlb have to internally allocate another page for doing DMA operations. This mechanism requires syncing the data from the internal page to the page which ixgbe sends to upper network stack. However, since commit f3213d932173 ("ixgbe: Update driver to make use of DMA attributes in Rx path"), the unmap operation is performed with DMA_ATTR_SKIP_CPU_SYNC. As a result, the sync is not performed. Since the sync isn't performed, the upper network stack could receive a incomplete network packet. By incomplete, it means the linear data on the first fragment(between skb->head and skb->end) is invalid. So we have to copy the data from the internal xen-swiotlb page to the page which ixgbe sends to upper network stack through the sync operation. More details from Alexander Duyck: Specifically since we are mapping the frame with DMA_ATTR_SKIP_CPU_SYNC we have to unmap with that as well. As a result a sync is not performed on an unmap and must be done manually as we skipped it for the first frag. As such we need to always sync before possibly performing a page unmap operation.

Initially the intention was to implement it using netdev_dbg, analogously to what is done in ixgbe for instance.

2019-09-09fm10k: use a local variable for the frag pointerJacob Keller
In the function fm10k_xmit_frame_ring, we recently switched to using the skb_frag_size accessor instead of directly using the size member of the skb fragment. This made the for loop slightly harder to read because it created a very long line that is difficult to split up. Avoid this by using a local variable in the for loop, so that we do not have to break the line on an open parenthesis.

2019-09-09e1000e: Make speed detection on hotplugging cable more reliableKai-Heng Feng
After hot plugging an 1Gbps Ethernet cable with 1Gbps link partner, the MII_BMSR may report 10Mbps, renders the network rather slow. The issue has much lower fail rate after commit 59653e6497d1 ("e1000e: Make watchdog use delayed work"), which essentially introduces some delay before running the watchdog task. But there's still a chance that the hot plugging event and the queued watchdog task gets run at the same time, then the original issue can be observed once again. So let's use mod_delayed_work() to add a deterministic 1 second delay before running watchdog task, after an interrupt.

2019-09-09virtio_ring: fix unmap of indirect descriptorsMatthias Lange
The function virtqueue_add_split() DMA-maps the scatterlist buffers. In case a mapping error occurs the already mapped buffers must be unmapped. This happens by jumping to the 'unmap_release' label. In case of indirect descriptors the release is wrong and may leak kernel memory. Because the implementation assumes that the head descriptor is already mapped it starts iterating over the descriptor list starting from the head descriptor. However for indirect descriptors the head descriptor is never mapped in case of an error. The fix is to initialize the start index with zero in case of indirect descriptors and use the 'desc' pointer directly for iterating over the descriptor chain.

Sebastian reports that after commit ff296293b353 ("random: Support freezable kthreads in add_hwgenerator_randomness()") we can call might_sleep() when the task state is TASK_INTERRUPTIBLE (state=1).
