[PATCH 1/1] usb: gadget: f_fs: set req->num_sgs as 0 for sync io mode

by Peter Chen

The UDC core uses req->num_sgs to judge if scatter buffer list is used. Eg: usb_gadget_map_request_by_dev. For f_fs sync io mode, the request is re-used for each request, so if the 1st request->length > PAGE_SIZE, and the 2nd request->length is < PAGE_SIZE, the f_fs uses the 1st req->num_sgs for the 2nd request, it causes the UDC core get the wrong req->num_sgs value (The 2nd request doesn't use sg). We set req->num_sgs as 0 for each request at non-sg transfer case to fix it.

[PATCH v2] ARM: dma-api: fix max_pfn off-by-one error in __dma_supported()

by Chen-Yu Tsai

From: Chen-Yu Tsai <wens(a)csie.org> max_pfn, as set in arch/arm/mm/init.c: static void __init find_limits(unsigned long *min, unsigned long *max_low, unsigned long *max_high) { *max_low = PFN_DOWN(memblock_get_current_limit()); *min = PFN_UP(memblock_start_of_DRAM()); *max_high = PFN_DOWN(memblock_end_of_DRAM()); } with memblock_end_of_DRAM() pointing to the next byte after DRAM. As such, max_pfn points to the PFN after the end of DRAM. Thus when using max_pfn to check DMA masks, we should subtract one when checking DMA ranges against it. Commit 8bf1268f48ad ("ARM: dma-api: fix off-by-one error in __dma_supported()") fixed the same issue, but missed this spot. This issue was found while working on the sun4i-csi v4l2 driver on the Allwinner R40 SoC. On Allwinner SoCs, DRAM is offset at 0x40000000, and we are starting to use of_dma_configure() with the "dma-ranges" property in the device tree to have the DMA API handle the offset. In this particular instance, dma-ranges was set to the same range as the actual available (2 GiB) DRAM. The following error appeared when the driver attempted to allocate a buffer: sun4i-csi 1c09000.csi: Coherent DMA mask 0x7fffffff (pfn 0x40000-0xc0000) covers a smaller range of system memory than the DMA zone pfn 0x0-0xc0001 sun4i-csi 1c09000.csi: dma_alloc_coherent of size 307200 failed Fixing the off-by-one error makes things work.

[PATCH AUTOSEL 4.14 01/58] scsi: lpfc: Fix discovery failures when target device connectivity bounces

by Sasha Levin

From: James Smart <jsmart2021(a)gmail.com> [ Upstream commit 3f97aed6117c7677eb16756c4ec8b86000fd5822 ] An issue was seen discovering all SCSI Luns when a target device undergoes link bounce. The driver currently does not qualify the FC4 support on the target. Therefore it will send a SCSI PRLI and an NVMe PRLI. The expectation is that the target will reject the PRLI if it is not supported. If a PRLI times out, the driver will retry. The driver will not proceed with the device until both SCSI and NVMe PRLIs are resolved. In the failure case, the device is FCP only and does not respond to the NVMe PRLI, thus initiating the wait/retry loop in the driver. During that time, a RSCN is received (device bounced) causing the driver to issue a GID_FT. The GID_FT response comes back before the PRLI mess is resolved and it prematurely cancels the PRLI retry logic and leaves the device in a STE_PRLI_ISSUE state. Discovery with the target never completes or resets. Fix by resetting the node state back to STE_NPR_NODE when GID_FT completes, thereby restarting the discovery process for the node.

[PATCH v2] KVM: x86: use CPUID to locate host page table reserved bits

by Paolo Bonzini

The comment in kvm_get_shadow_phys_bits refers to MKTME, but the same is actually true of SME and SEV. Just use CPUID[0x8000_0008].EAX[7:0] unconditionally if available, it is simplest and works even if memory is not encrypted.
