From f813f21971b96f61a789dd48151f92220fdd2e0a Mon Sep 17 00:00:00 2001 From: Jérôme Glisse Date: Tue, 30 Oct 2018 15:04:06 -0700 Subject: mm/hmm: fix utf8 ... MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Patch series "HMM updates, improvements and fixes", v2 Few fixes that only affect HMM users. Improve the synchronization call back so that we match was other mmu_notifier listener do and add proper support to the new blockable flags in the process. For curious folks here are branches to leverage HMM in various existing device drivers: https://cgit.freedesktop.org/~glisse/linux/log/?h=hmm-nouveau-v01 https://cgit.freedesktop.org/~glisse/linux/log/?h=hmm-radeon-v00 https://cgit.freedesktop.org/~glisse/linux/log/?h=hmm-intel-v00 More to come (amd gpu, Mellanox, ...) I expect more of the preparatory work for nouveau will be merge in 4.20 (like we have been doing since 4.16) and i will wait until this patchset is upstream before pushing the patches that actualy make use of HMM (to avoid complex tree inter-dependency). This patch (of 6): Somehow utf=8 must have been broken.

This make it easier when adding new parameters by avoiding having to update all callback function signature. The hmm_update structure is always associated with a mmu_notifier callbacks so we are not planing on grouping multiple updates together. Nor do we care about page size for the range as range will over fully cover the page being invalidated (this is a mmu_notifier property).

I had the 0-day buildbot chew on a patch [1] that would cause build failures for such cases without complaining, suggesting that we don't have any such users currently, at least for the 70 .config/arch combinations that was built. Should any turn up, make sure they use the out-of-line versions, which do handle nbits==0 correctly. This is of course not the most efficient, but it's much less churn than teaching all the static inlines an "if (zero_const_nbits())", and since we don't have any current instances, this doesn't affect existing code at all.

If a bit is 1, - * the page is allocated and 0 if unallocated. To satisfy allocations - * of sizes smaller than a page, the allocator records the Page Frame - * Number (PFN) of the last allocation and the offset the allocation - * ended at. Subsequent small allocations are merged together and - * stored on the same page. - * - * The information used by the bootmem allocator is represented by - * :c:type:`struct bootmem_data`. An array to hold up to %MAX_NUMNODES - * such structures is statically allocated and then it is discarded - * when the system initialization completes. Each entry in this array - * corresponds to a node with memory. For UMA systems only entry 0 is - * used. - * - * The bootmem allocator is initialized during early architecture - * specific setup. Each architecture is required to supply a - * :c:func:`setup_arch` function which, among other tasks, is - * responsible for acquiring the necessary parameters to initialise - * the boot memory allocator. These parameters define limits of usable - * physical memory: - * - * * @min_low_pfn - the lowest PFN that is available in the system - * * @max_low_pfn - the highest PFN that may be addressed by low - * memory (%ZONE_NORMAL) - * * @max_pfn - the last PFN available to the system. - * - * After those limits are determined, the :c:func:`init_bootmem` or - * :c:func:`init_bootmem_node` function should be called to initialize - * the bootmem allocator. The UMA case should use the `init_bootmem` - * function. It will initialize ``contig_page_data`` structure that - * represents the only memory node in the system. In the NUMA case the - * `init_bootmem_node` function should be called to initialize the - * bootmem allocator for each node. - * - * Once the allocator is set up, it is possible to use either single - * node or NUMA variant of the allocation APIs. - */ - -#ifndef CONFIG_NEED_MULTIPLE_NODES -struct pglist_data __refdata contig_page_data = { - .bdata = &bootmem_node_data[0] -}; -EXPORT_SYMBOL(contig_page_data); -#endif - -unsigned long max_low_pfn; -unsigned long min_low_pfn; -unsigned long max_pfn; -unsigned long long max_possible_pfn; - -bootmem_data_t bootmem_node_data[MAX_NUMNODES] __initdata; - -static struct list_head bdata_list __initdata = LIST_HEAD_INIT(bdata_list); - -static int bootmem_debug; - -static int __init bootmem_debug_setup(char *buf) -{ - bootmem_debug = 1; - return 0; -} -early_param("bootmem_debug", bootmem_debug_setup); - -#define bdebug(fmt, args...)

Replace calls to free_bootmem_late with calls to memblock_free_late and remove the bootmem variant.

implicit alignment to SMP_CACHE_BYTES When a memblock allocation APIs are called with align = 0, the alignment is implicitly set to SMP_CACHE_BYTES. Implicit alignment is done deep in the memblock allocator and it can come as a surprise. Not that such an alignment would be wrong even when used incorrectly but it is better to be explicit for the sake of clarity and the prinicple of the least surprise. Replace all such uses of memblock APIs with the 'align' parameter explicitly set to SMP_CACHE_BYTES and stop implicit alignment assignment in the memblock internal allocation functions. For the case when memblock APIs are used via helper functions, e.g. like iommu_arena_new_node() in Alpha, the helper functions were detected with Coccinelle's help and then manually examined and updated where appropriate. The direct memblock APIs users were updated using the semantic patch below: @@ expression size, min_addr, max_addr, nid; @@ ( | - memblock_alloc_try_nid_raw(size, 0, min_addr, max_addr, nid) + memblock_alloc_try_nid_raw(size, SMP_CACHE_BYTES, min_addr, max_addr, nid) | - memblock_alloc_try_nid_nopanic(size, 0, min_addr, max_addr, nid) + memblock_alloc_try_nid_nopanic(size, SMP_CACHE_BYTES, min_addr, max_addr, nid) | - memblock_alloc_try_nid(size, 0, min_addr, max_addr, nid) + memblock_alloc_try_nid(size, SMP_CACHE_BYTES, min_addr, max_addr, nid) | - memblock_alloc(size, 0) + memblock_alloc(size, SMP_CACHE_BYTES) | - memblock_alloc_raw(size, 0) + memblock_alloc_raw(size, SMP_CACHE_BYTES) | - memblock_alloc_from(size, 0, min_addr) + memblock_alloc_from(size, SMP_CACHE_BYTES, min_addr) | - memblock_alloc_nopanic(size, 0) + memblock_alloc_nopanic(size, SMP_CACHE_BYTES) | - memblock_alloc_low(size, 0) + memblock_alloc_low(size, SMP_CACHE_BYTES) | - memblock_alloc_low_nopanic(size, 0) + memblock_alloc_low_nopanic(size, SMP_CACHE_BYTES) | - memblock_alloc_from_nopanic(size, 0, min_addr) + memblock_alloc_from_nopanic(size, SMP_CACHE_BYTES, min_addr) | - memblock_alloc_node(size, 0, nid) + memblock_alloc_node(size, SMP_CACHE_BYTES, nid) ) [mhocko@suse.com: changelog update] [akpm@linux-foundation.org: coding-style fixes] [rppt@linux.ibm.com: fix missed uses of implicit alignment] Link: http://lkml.kernel.org/r/20181016133656.GA10925@rapoport-lnx Link: http://lkml.kernel.org/r/1538687224-17535-1-git-send-email-rppt@linux.vnet.ibm.com Signed-off-by: Mike Rapoport Suggested-by: Michal Hocko Acked-by: Paul Burton [MIPS] Acked-by: Michael Ellerman [powerpc] Acked-by: Michal Hocko Cc: Catalin Marinas Cc: Chris Zankel Cc: Geert Uytterhoeven Cc: Guan Xuetao Cc: Ingo Molnar Cc: Matt Turner Cc: Michal Simek Cc: Richard Weinberger Cc: Russell King Cc: Thomas Gleixner Cc: Tony Luck Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- arch/alpha/kernel/core_apecs.c | 3 ++- arch/alpha/kernel/core_lca.c | 3 ++- arch/alpha/kernel/core_marvel.c | 4 ++-- arch/alpha/kernel/core_mcpcia.c | 6 +++-- arch/alpha/kernel/core_t2.c | 2 +- arch/alpha/kernel/core_titan.c | 6 +++-- arch/alpha/kernel/core_tsunami.c | 6 +++-- arch/alpha/kernel/core_wildfire.c | 6 +++-- arch/alpha/kernel/pci-noop.c | 4 ++-- arch/alpha/kernel/pci.c | 4 ++-- arch/alpha/kernel/pci_iommu.c | 4 ++-- arch/arm/kernel/setup.c | 4 ++-- arch/arm/mach-omap2/omap_hwmod.c | 8 ++++--- arch/arm64/kernel/setup.c | 2 +- arch/ia64/kernel/mca.c | 4 ++-- arch/ia64/mm/tlb.c | 6 +++-- arch/ia64/sn/kernel/io_common.c | 4 +++- arch/ia64/sn/kernel/setup.c | 5 ++-- arch/m68k/sun3/sun3dvma.c | 2 +- arch/microblaze/mm/init.c | 2 +- arch/mips/kernel/setup.c | 2 +- arch/powerpc/kernel/paca.c | 2 +- arch/powerpc/kernel/pci_32.c | 3 ++- arch/powerpc/lib/alloc.c | 2 +- arch/powerpc/mm/mmu_context_nohash.c | 7 +++--- arch/powerpc/platforms/powermac/nvram.c | 2 +- arch/powerpc/platforms/powernv/pci-ioda.c | 6 ++--- arch/powerpc/sysdev/msi_bitmap.c | 2 +- arch/um/drivers/net_kern.c | 2 +- arch/um/drivers/vector_kern.c | 2 +- arch/um/kernel/initrd.c | 2 +- arch/unicore32/kernel/setup.c | 2 +- arch/x86/kernel/acpi/boot.c | 2 +- arch/x86/kernel/apic/io_apic.c | 2 +- arch/x86/kernel/e820.c | 3 ++- arch/x86/platform/olpc/olpc_dt.c | 2 +- arch/xtensa/platforms/iss/network.c | 2 +- drivers/clk/ti/clk.c | 2 +- drivers/firmware/efi/memmap.c | 2 +- drivers/firmware/memmap.c | 3 ++- drivers/macintosh/smu.c | 2 +- drivers/of/of_reserved_mem.c | 1 + include/linux/memblock.h | 3 ++- init/main.c | 13 +++++++---- kernel/power/snapshot.c | 3 ++- lib/cpumask.c | 2 +- mm/memblock.c | 8 ------- mm/page_alloc.c | 6 +++-- mm/percpu.c | 38 ++++++++++++++++--------------- mm/sparse.c | 3 ++- 50 files changed, 120 insertions(+), 96 deletions(-) (limited to 'include/linux') diff --git a/arch/alpha/kernel/core_apecs.c b/arch/alpha/kernel/core_apecs.c index 1bf3eef34c22..6df765ff2b10 100644 --- a/arch/alpha/kernel/core_apecs.c +++ b/arch/alpha/kernel/core_apecs.c @@ -346,7 +346,8 @@ apecs_init_arch(void) * Window 1 is direct access 1GB at 1GB * Window 2 is scatter-gather 8MB at 8MB (for isa) */ - hose->sg_isa = iommu_arena_new(hose, 0x00800000, 0x00800000, 0);

Reading through the code and studying how mem_hotplug_lock is to be used, I noticed that there are two places where we can end up calling device_online()/device_offline() - online_pages()/offline_pages() without the mem_hotplug_lock. And there are other places where we call device_online()/device_offline() without the device_hotplug_lock. While e.g. echo "online" > /sys/devices/system/memory/memory9/state is fine, e.g. echo 1 > /sys/devices/system/memory/memory9/online Will not take the mem_hotplug_lock. However the device_lock() and device_hotplug_lock. E.g. via memory_probe_store(), we can end up calling add_memory()->online_pages() without the device_hotplug_lock. So we can have concurrent callers in online_pages(). We e.g. touch in online_pages() basically unprotected zone->present_pages then. Looks like there is a longer history to that (see Patch #2 for details), and fixing it to work the way it was intended is not really possible. We would e.g. have to take the mem_hotplug_lock in device/base/core.c, which sounds wrong. Summary: We had a lock inversion on mem_hotplug_lock and device_lock(). More details can be found in patch 3 and patch 6. I propose the general rules (documentation added in patch 6): 1. add_memory/add_memory_resource() must only be called with device_hotplug_lock. 2. remove_memory() must only be called with device_hotplug_lock. This is already documented and holds for all callers. 3. device_online()/device_offline() must only be called with device_hotplug_lock. This is already documented and true for now in core code. Other callers (related to memory hotplug) have to be fixed up. 4. mem_hotplug_lock is taken inside of add_memory/remove_memory/ online_pages/offline_pages. To me, this looks way cleaner than what we have right now (and easier to verify). And looking at the documentation of remove_memory, using lock_device_hotplug also for add_memory() feels natural. This patch (of 6): remove_memory() is exported right now but requires the device_hotplug_lock, which is not exported. So let's provide a variant that takes the lock and only export that one. The lock is already held in arch/powerpc/platforms/pseries/hotplug-memory.c drivers/acpi/acpi_memhotplug.c arch/powerpc/platforms/powernv/memtrace.c Apart from that, there are not other users in the tree.

In general, we should hold the device_hotplug_lock when adding memory to synchronize against online/offline request (e.g. from user space) - which already resulted in lock inversions due to device_lock() and mem_hotplug_lock - see 30467e0b3be ("mm, hotplug: fix concurrent memory hot-add deadlock"). add_memory()/add_memory_resource() will create memory block devices, so this really feels like the right thing to do. Holding the device_hotplug_lock makes sure that a memory block device can really only be accessed (e.g. via .online/.state) from user space, once the memory has been fully added to the system. The lock is not held yet in drivers/xen/balloon.c arch/powerpc/platforms/powernv/memtrace.c drivers/s390/char/sclp_cmd.c drivers/hv/hv_balloon.c So, let's either use the locked variants or take the lock. Don't export add_memory_resource(), as it once was exported to be used by XEN, which is never built as a module. If somebody requires it, we also have to export a locked variant (as device_hotplug_lock is never exported).
