2018-05-22qed: Fix mask for physical address in ILT entryShahed Shaikh
ILT entry requires 12 bit right shifted physical address. Existing mask for ILT entry of physical address i.e. ILT_ENTRY_PHY_ADDR_MASK is not sufficient to handle 64bit address because upper 8 bits of 64 bit address were getting masked which resulted in completer abort error on PCIe bus due to invalid address. Fix that mask to handle 64bit physical address.

2018-05-22isdn: eicon: fix a missing-check bugWenwen Wang
In divasmain.c, the function divas_write() firstly invokes the function diva_xdi_open_adapter() to open the adapter that matches with the adapter number provided by the user, and then invokes the function diva_xdi_write() to perform the write operation using the matched adapter. The two functions diva_xdi_open_adapter() and diva_xdi_write() are located in diva.c. In diva_xdi_open_adapter(), the user command is copied to the object 'msg' from the userspace pointer 'src' through the function pointer 'cp_fn', which eventually calls copy_from_user() to do the copy. Then, the adapter number 'msg.adapter' is used to find out a matched adapter from the 'adapter_queue'. A matched adapter will be returned if it is found. Otherwise, NULL is returned to indicate the failure of the verification on the adapter number. As mentioned above, if a matched adapter is returned, the function diva_xdi_write() is invoked to perform the write operation. In this function, the user command is copied once again from the userspace pointer 'src', which is the same as the 'src' pointer in diva_xdi_open_adapter() as both of them are from the 'buf' pointer in divas_write(). Similarly, the copy is achieved through the function pointer 'cp_fn', which finally calls copy_from_user(). After the successful copy, the corresponding command processing handler of the matched adapter is invoked to perform the write operation. It is obvious that there are two copies here from userspace, one is in diva_xdi_open_adapter(), and one is in diva_xdi_write(). Plus, both of these two copies share the same source userspace pointer, i.e., the 'buf' pointer in divas_write(). Given that a malicious userspace process can race to change the content pointed by the 'buf' pointer, this can pose potential security issues. For example, in the first copy, the user provides a valid adapter number to pass the verification process and a valid adapter can be found. Then the user can modify the adapter number to an invalid number. This way, the user can bypass the verification process of the adapter number and inject inconsistent data. This patch reuses the data copied in diva_xdi_open_adapter() and passes it to diva_xdi_write(). This way, the above issues can be avoided.

2018-05-22PM / core: Fix direct_complete handling for devices with no callbacksRafael J. Wysocki
Commit 08810a4119aa (PM / core: Add NEVER_SKIP and SMART_PREPARE driver flags) inadvertently prevented the power.direct_complete flag from being set for devices without PM callbacks and with disabled runtime PM which also prevents power.direct_complete from being set for their parents. That led to problems including a resume crash on HP ZBook 14u. Restore the previous behavior by causing power.direct_complete to be set for those devices again, but do that in a more direct way to avoid overlooking that case in the future.

2018-05-21loop: clear wb_err in bd_inode when detaching backing fileJeff Layton
When a loop block device encounters a writeback error, that error will get propagated to the bd_inode's wb_err field. If we then detach the backing file from it, attach another and fsync it, we'll get back the writeback error that we had from the previous backing file. This is a bit of a grey area as POSIX doesn't cover loop devices, but it is somewhat counterintuitive. If we detach a backing file from the loopdev while there are still unreported errors, take it as a sign that we're no longer interested in the previous file, and clear out the wb_err in the loop blockdev.

2018-05-21mmc: sdhci-iproc: fix 32bit writes for TRANSFER_MODE registerCorneliu Doban
When the host controller accepts only 32bit writes, the value of the 16bit TRANSFER_MODE register, that has the same 32bit address as the 16bit COMMAND register, needs to be saved and it will be written in a 32bit write together with the command as this will trigger the host to send the command on the SD interface. When sending the tuning command, TRANSFER_MODE is written and then sdhci_set_transfer_mode reads it back to clear AUTO_CMD12 bit and write it again resulting in wrong value to be written because the initial write value was saved in a shadow and the read-back returned a wrong value, from the register. Fix sdhci_iproc_readw to return the saved value of TRANSFER_MODE when a saved value exist. Same fix for read of BLOCK_SIZE and BLOCK_COUNT registers, that are saved for a different reason, although a scenario that will cause the mentioned problem on this registers is not probable.

The connector .atomic_check() handler can be called with a NULL crtc pointer in the connector state when the connector gets disabled explicitly (through performing a legacy mode set or setting the connector's CRTC_ID property to 0). This causes a crash as the crtc pointer is dereferenced without any check. Fix it by returning from the .atomic_check() handler when then crtc pointer is NULL, as there is no check to be performed when the connector gets disabled.

2018-05-19efi/libstub/arm64: Handle randomized TEXT_OFFSETMark Rutland
When CONFIG_RANDOMIZE_TEXT_OFFSET=y, TEXT_OFFSET is an arbitrary multiple of PAGE_SIZE in the interval [0, 2MB). The EFI stub does not account for the potential misalignment of TEXT_OFFSET relative to EFI_KIMG_ALIGN, and produces a randomized physical offset which is always a round multiple of EFI_KIMG_ALIGN. This may result in statically allocated objects whose alignment exceeds PAGE_SIZE to appear misaligned in memory. This has been observed to result in spurious stack overflow reports and failure to make use of the IRQ stacks, and theoretically could result in a number of other issues. We can OR in the low bits of TEXT_OFFSET to ensure that we have the necessary offset (and hence preserve the misalignment of TEXT_OFFSET relative to EFI_KIMG_ALIGN), so let's do that.

2018-05-18xen-swiotlb: fix the check condition for xen_swiotlb_free_coherentJoe Jin
When run raidconfig from Dom0 we found that the Xen DMA heap is reduced, but Dom Heap is increased by the same size. Tracing raidconfig we found that the related ioctl() in megaraid_sas will call dma_alloc_coherent() to apply memory. If the memory allocated by Dom0 is not in the DMA area, it will exchange memory with Xen to meet the requiment. Later drivers call dma_free_coherent() to free the memory, on xen_swiotlb_free_coherent() the check condition (dev_addr + size - 1 <= dma_mask) is always false, it prevents calling xen_destroy_contiguous_region() to return the memory to the Xen DMA heap. This issue introduced by commit 6810df88dcfc2 "xen-swiotlb: When doing coherent alloc/dealloc check before swizzling the MFNs.".

2018-05-18sh_eth: Change platform check to CONFIG_ARCH_RENESASGeert Uytterhoeven
Since commit 9b5ba0df4ea4f940 ("ARM: shmobile: Introduce ARCH_RENESAS") is CONFIG_ARCH_RENESAS a more appropriate platform check than the legacy CONFIG_ARCH_SHMOBILE, hence use the former. Renesas SuperH SH-Mobile SoCs are still covered by the CONFIG_CPU_SH4 check. This will allow to drop ARCH_SHMOBILE on ARM and ARM64 in the near future.

Commit 539d39eb2708 ("bcache: fix wrong return value in bch_debug_init()") returns the return value of debugfs_create_dir() to bcache_init(). When CONFIG_DEBUG_FS=n, bch_debug_init() always returns 1 and makes bcache_init() failedi. This patch makes bch_debug_init() always returns 0 if CONFIG_DEBUG_FS=n, so bcache can continue to work for the kernels which don't have debugfs enanbled.
