2018-11-27altera-stapl: check for a null key before strcasecmp'ing itColin Ian King1-2/+1
Currently the null check on key is occurring after the strcasecmp on the key, hence there is a potential null pointer dereference on key. Fix this by checking if key is null first. Also replace the == 0 check on strcasecmp with just the ! operator.

Commit d86adf482b84 ("scsi: storvsc: Enable multi-queue support") removed the usage of the API in Jan 2017, and the API is not used since then. netvsc and storvsc have their own algorithms to determine the outgoing channel, so this API is useless. And the API is potentially unsafe, because it reads primary->num_sc without any lock held. This can be risky considering the RESCIND-OFFER message. Let's remove the API.

2018-11-26firmware: add Intel Stratix10 service layer driverRichard Gong5-0/+1492
Some features of the Intel Stratix10 SoC require a level of privilege higher than the kernel is granted. Such secure features include FPGA programming. In terms of the ARMv8 architecture, the kernel runs at Exception Level 1 (EL1), access to the features requires Exception Level 3 (EL3). The Intel Stratix10 SoC service layer provides an in kernel API for drivers to request access to the secure features. The requests are queued and processed one by one. ARM’s SMCCC is used to pass the execution of the requests on to a secure monitor (EL3). The header file stratix10-sve-client.h defines the interface between service providers (FPGA manager is one of them) and service layer. The header file stratix10-smc.h defines the secure monitor call (SMC) message protocols used for service layer driver in normal world (EL1) to communicate with secure monitor SW in secure monitor exception level 3 (EL3).

2018-11-26fpga: mgr: altera-ps-spi: enable usage on non-dt platformsAnatolij Gustschin1-5/+35
Driver probing fails on non-dt platforms since of_match_device() always returns NULL here. Add spi ids with device names and matching driver data as an index of a map array with data for supported devices. Add this map array and a function for mapping spi ids to driver data. This allows driver binding to dynamically added PS-SPI devices (e.g. when added via spi_new_device() after hot-plugging).

Pull xfs fixes from Darrick Wong: "Dave and I have continued our work fixing corruption problems that can be found when running long-term burn-in exercisers on xfs. Here are some patches fixing most of the problems, but there will likely be more. :/ - Numerous corruption fixes for copy on write - Numerous corruption fixes for blocksize < pagesize writes - Don't miscalculate AG reservations for small final AGs - Fix page cache truncation to work properly for reflink and extent shifting - Fix use-after-free when retrying failed inode/dquot buffer logging - Fix corruptions seen when using copy_file_range in directio mode" * tag 'xfs-4.20-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: iomap: readpages doesn't zero page tail beyond EOF vfs: vfs_dedupe_file_range() doesn't return EOPNOTSUPP iomap: dio data corruption and spurious errors when pipes fill iomap: sub-block dio needs to zeroout beyond EOF iomap: FUA is wrong for DIO O_DSYNC writes into unwritten extents xfs: delalloc -> unwritten COW fork allocation can go wrong xfs: flush removing page cache in xfs_reflink_remap_prep xfs: extent shifting doesn't fully invalidate page cache xfs: finobt AG reserves don't consider last AG can be a runt xfs: fix transient reference count error in xfs_buf_resubmit_failed_buffers xfs: uncached buffer tracing needs to print bno xfs: make xfs_file_remap_range() static xfs: fix shared extent data corruption due to missing cow reservation

2018-11-24net: phy: mscc: fix deadlock in vsc85xx_default_configQuentin Schulz1-9/+5
The vsc85xx_default_config function called in the vsc85xx_config_init function which is used by VSC8530, VSC8531, VSC8540 and VSC8541 PHYs mistakenly calls phy_read and phy_write in-between phy_select_page and phy_restore_page. phy_select_page and phy_restore_page actually take and release the MDIO bus lock and phy_write and phy_read take and release the lock to write or read to a PHY register. Let's fix this deadlock by using phy_modify_paged which handles correctly a read followed by a write in a non-standard page.

Reset snd_queue tso_hdrs pointer to NULL in nicvf_free_snd_queue routine since it is used to check if tso dma descriptor queue has been previously allocated.
