2024-04-01drm/mediatek: Init `ddp_comp` with devm_kcalloc()Douglas Anderson
In the case where `conn_routes` is true we allocate an extra slot in the `ddp_comp` array but mtk_drm_crtc_create() never seemed to initialize it in the test case I ran. For me, this caused a later crash when we looped through the array in mtk_drm_crtc_mode_valid(). This showed up for me when I booted with `slub_debug=FZPUA` which poisons the memory initially. Without `slub_debug` I couldn't reproduce, presumably because the later code handles the value being NULL and in most cases (not guaranteed in all cases) the memory the allocator returned started out as 0. It really doesn't hurt to initialize the array with devm_kcalloc() since the array is small and the overhead of initting a handful of elements to 0 is small. In general initting memory to zero is a safer practice and usually it's suggested to only use the non-initting alloc functions if you really need to. Let's switch the function to use an allocation function that zeros the memory. For me, this avoids the crash.

2024-03-24x86/efistub: Don't clear BSS twice in mixed modeArd Biesheuvel
Clearing BSS should only be done once, at the very beginning. efi_pe_entry() is the entrypoint from the firmware, which may not clear BSS and so it is done explicitly. However, efi_pe_entry() is also used as an entrypoint by the mixed mode startup code, in which case BSS will already have been cleared, and doing it again at this point will corrupt global variables holding the firmware's GDT/IDT and segment selectors. So make the memset() conditional on whether the EFI stub is running in native mode.

Pull more SCSI updates from James Bottomley: "The vfs has long had a write lifetime hint mechanism that gives the expected longevity on storage of the data being written. f2fs was the original consumer of this and used the hint for flash data placement (mostly to avoid write amplification by placing objects with similar lifetimes in the same erase block). More recently the SCSI based UFS (Universal Flash Storage) drivers have wanted to take advantage of this as well, for the same reasons as f2fs, necessitating plumbing the write hints through the block layer and then adding it to the SCSI core. The vfs write_hints already taken plumbs this as far as block and this completes the SCSI core enabling based on a recently agreed reuse of the old write command group number. The additions to the scsi_debug driver are for emulating this property so we can run tests on it in the absence of an actual UFS device" * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: scsi_debug: Maintain write statistics per group number scsi: scsi_debug: Implement GET STREAM STATUS scsi: scsi_debug: Implement the IO Advice Hints Grouping mode page scsi: scsi_debug: Allocate the MODE SENSE response from the heap scsi: scsi_debug: Rework subpage code error handling scsi: scsi_debug: Rework page code error handling scsi: scsi_debug: Support the block limits extension VPD page scsi: scsi_debug: Reduce code duplication scsi: sd: Translate data lifetime information scsi: scsi_proto: Add structures and constants related to I/O groups and streams scsi: core: Query the Block Limits Extension VPD page

2024-03-22efi/libstub: fix efi_random_alloc() to allocate memory at alloc_min or ↵KONDO KAZUMA(近藤 和真)
higher address Following warning is sometimes observed while booting my servers: [ 3.594838] DMA: preallocated 4096 KiB GFP_KERNEL pool for atomic allocations [ 3.602918] swapper/0: page allocation failure: order:10, mode:0xcc1(GFP_KERNEL|GFP_DMA), nodemask=(null),cpuset=/,mems_allowed=0-1 ... [ 3.851862] DMA: preallocated 1024 KiB GFP_KERNEL|GFP_DMA pool for atomic allocation If 'nokaslr' boot option is set, the warning always happens. On x86, ZONE_DMA is small zone at the first 16MB of physical address space. When this problem happens, most of that space seems to be used by decompressed kernel. Thereby, there is not enough space at DMA_ZONE to meet the request of DMA pool allocation. The commit 2f77465b05b1 ("x86/efistub: Avoid placing the kernel below LOAD_PHYSICAL_ADDR") tried to fix this problem by introducing lower bound of allocation. But the fix is not complete. efi_random_alloc() allocates pages by following steps. 1. Count total available slots ('total_slots') 2. Select a slot ('target_slot') to allocate randomly 3. Calculate a starting address ('target') to be included target_slot 4. Allocate pages, which starting address is 'target' In step 1, 'alloc_min' is used to offset the starting address of memory chunk. But in step 3 'alloc_min' is not considered at all. As the result, 'target' can be miscalculated and become lower than 'alloc_min'. When KASLR is disabled, 'target_slot' is always 0 and the problem happens everytime if the EFI memory map of the system meets the condition. Fix this problem by calculating 'target' considering 'alloc_min'.
