The code uses a bitmap to check for duplicate tokens during parsing, and that doesn't work at all for the negative Opt_err token case. There is absolutely no reason to make Opt_err be negative, and in fact it only confuses things, since some of the affected functions actually return a positive Opt_xyz enum _or_ a regular negative error code (eg -EINVAL), and using -1 for Opt_err makes no sense. There are similar problems in ima_policy.c and key encryption, but they don't have the immediate bug wrt bitmap handing, and ima_policy.c in particular needs a different patch to make the enum values match the token array index. Mimi is sending that separately.

Lendacky, Thomas authored
The dma_direct_supported() function intends to check the DMA mask against specific values. However, the phys_to_dma() function includes the SME encryption mask, which defeats the intended purpose of the check. This results in drivers that support less than 48-bit DMA (SME encryption mask is bit 47) from being able to set the DMA mask successfully when SME is active, which results in the driver failing to initialize. Change the function used to check the mask from phys_to_dma() to __phys_to_dma() so that the SME encryption mask is not part of the check.

The spdxcheck script currently falls over when confronted with a binary file (such as Documentation/logo.gif). To avoid that, always open files in binary mode and decode line-by-line, ignoring encoding errors. One tricky case is when piping data into the script and reading it from standard input. By default, standard input will be opened in text mode, so we need to reopen it in binary mode. The breakage only happens with python3 and results in a UnicodeDecodeError (according to Uwe).

There is actually a space after "sp," like this, ffff2000080813c8: a9bb7bfd stp x29, x30, [sp, #-80]! Right now, checkstack.pl isn't able to print anything on aarch64, because it won't be able to match the stating objdump line of a function due to this missing space. Hence, it displays every stack as zero-size. After this patch, checkpatch.pl is able to match the start of a function's objdump, and is then able to calculate each function's stack correctly.

Piotr Jaroszynski authored
migrate_page_move_mapping() expects pages with private data set to have a page_count elevated by 1. This is what used to happen for xfs through the buffer_heads code before the switch to iomap in commit 82cb1417 ("xfs: add support for sub-pagesize writeback without buffer_heads"). Not having the count elevated causes move_pages() to fail on memory mapped files coming from xfs. Make iomap compatible with the migrate_page_move_mapping() assumption by elevating the page count as part of iomap_page_create() and lowering it in iomap_page_release(). It causes the move_pages() syscall to misbehave on memory mapped files from xfs. It does not not move any pages, which I suppose is "just" a perf issue, but it also ends up returning a positive number which is out of spec for the syscall. Talking to Michal Hocko, it sounds like returning positive numbers might be a necessary update to move_pages() anyway though (https://lkml.kernel.org/r/20181116114955.GJ14706@dhcp22.suse.cz). I only hit this in tests that verify that move_pages() actually moved the pages. The test also got confused by the positive return from move_pages() (it got treated as a success as positive numbers were not expected and not handled) making it a bit harder to track down what's going on.

A stack trace was triggered by VM_BUG_ON_PAGE(page_mapcount(page), page) in free_huge_page(). Unfortunately, the page->mapping field was set to NULL before this test. This made it more difficult to determine the root cause of the problem. Move the VM_BUG_ON_PAGE tests earlier in the function so that if they do trigger more information is present in the page struct.

The conversion of alpha to memblock as the early memory manager caused boot to hang as described at [1]. The issue is caused because for CONFIG_DISCTONTIGMEM=y case, memblock_add() is called using memory start PFN that had been rounded down to the nearest 8Mb and it caused memblock to see more memory that is actually present in the system. Besides, memblock allocates memory from high addresses while bootmem was using low memory, which broke the assumption that early allocations are always accessible by the hardware. This patch ensures that memblock_add() is using the correct PFN for the memory start and forces memblock to use bottom-up allocations.

One is a performance regression, so not necessarily strictly a fix, but it was small and reasonable and claimed to avoid thrashing in the scheduler, so I took it. The remaining are all legitimate fixes that match the "we take fixes any time" criteria. Summary: - One performance regression for hfi1 - One kasan fix for hfi1 - A couple mlx5 fixes - A core oops fix" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: IB/core: Fix oops in netdev_next_upper_dev_rcu() IB/mlx5: Block DEVX umem from the non applicable cases IB/mlx5: Fix implicit ODP interrupted page fault IB/hfi1: Fix an out-of-bounds access in get_hw_stats IB/hfi1: Fix a latency issue for small messages

With the new validation code, a malicious user-space app could potentially submit command streams with enough buffer-object and resource references in them to have the resulting allocated validion nodes and relocations make the kernel run out of GFP_KERNEL memory. Protect from this by having the validation code reserve TTM graphics memory when allocating.

Merge tag 'for-4.20/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: - Fix DM cache metadata to verify that a cache has block before trying to continue with operation that requires them. - Fix bio-based DM core's dm_make_request() to properly impose device limits on individual bios by making use of blk_queue_split(). - Fix long-standing race with how DM thinp notified userspace of thin-pool mode state changes before they were actually made. - Fix the zoned target's bio completion handling; this is a fairly invassive fix at this stage but it is localized to the zoned target. Any zoned target users will benefit from this fix. * tag 'for-4.20/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm thin: bump target version dm thin: send event about thin-pool state change _after_ making it dm zoned: Fix target BIO completion handling dm: call blk_queue_split() to impose device limits on bios dm cache metadata: verify cache has blocks in blocks_are_clean_separate_dirty()

Pull media fixes from Mauro Carvalho Chehab: - one regression at vsp1 driver - some last time changes for the upcoming request API logic and for stateless codec support.
