Vinayak Menon	055a204262	mm: process_reclaim: support reclaim of driver owned pages ... GPU drivers can allocate memory via shmem and these pages may or may not be mapped to userspace at any moment. But these pages are allocated on behalf of userspace tasks. It is ideal to swapout the unmapped pages of a task during process reclaim. But as process reclaims works on mappings to derive pages, it misses the unmapped gpu pages. Add an option to reclaim these pages. Drivers can register to the reclaim notifier and call into the reclaim function with the mapping that contains these mapped/unmapped pages.

Buddy Lumpkin	7e78bc0ad2	vmscan: Support multiple kswapd threads per node ... Page replacement is handled in the Linux Kernel in one of two ways: 1) Asynchronously via kswapd 2) Synchronously, via direct reclaim At page allocation time the allocating task is immediately given a page from the zone free list allowing it to go right back to work doing whatever it was doing; Probably directly or indirectly executing business logic. Just prior to satisfying the allocation, free pages is checked to see if it has reached the zone low watermark and if so, kswapd is awakened. Kswapd will start scanning pages looking for inactive pages to evict to make room for new page allocations. The work of kswapd allows tasks to continue allocating memory from their respective zone free list without incurring any delay. When the demand for free pages exceeds the rate that kswapd tasks can supply them, page allocation works differently. Once the allocating task finds that the number of free pages is at or below the zone min watermark, the task will no longer pull pages from the free list. Instead, the task will run the same CPU-bound routines as kswapd to satisfy its own allocation by scanning and evicting pages. This is called a direct reclaim. The time spent performing a direct reclaim can be substantial, often taking tens to hundreds of milliseconds for small order0 allocations to half a second or more for order9 huge-page allocations. In fact, kswapd is not actually required on a linux system. It exists for the sole purpose of optimizing performance by preventing direct reclaims. When memory shortfall is sufficient to trigger direct reclaims, they can occur in any task that is running on the system. A single aggressive memory allocating task can set the stage for collateral damage to occur in small tasks that rarely allocate additional memory. Consider the impact of injecting an additional 100ms of latency when nscd allocates memory to facilitate caching of a DNS query. The presence of direct reclaims 10 years ago was a fairly reliable indicator that too much was being asked of a Linux system. Kswapd was likely wasting time scanning pages that were ineligible for eviction. Adding RAM or reducing the working set size would usually make the problem go away. Since then hardware has evolved to bring a new struggle for kswapd. Storage speeds have increased by orders of magnitude while CPU clock speeds stayed the same or even slowed down in exchange for more cores per package. This presents a throughput problem for a single threaded kswapd that will get worse with each generation of new hardware. Test Details NOTE: The tests below were run with shadow entries disabled. See the associated patch and cover letter for details The tests below were designed with the assumption that a kswapd bottleneck is best demonstrated using filesystem reads. This way, the inactive list will be full of clean pages, simplifying the analysis and allowing kswapd to achieve the highest possible steal rate. Maximum steal rates for kswapd are likely to be the same or lower for any other mix of page types on the system. Tests were run on a 2U Oracle X7-2L with 52 Intel Xeon Skylake 2GHz cores, 756GB of RAM and 8 x 3.6 TB NVMe Solid State Disk drives. Each drive has an XFS file system mounted separately as /d0 through /d7. SSD drives require multiple concurrent streams to show their potential, so I created eleven 250GB zero-filled files on each drive so that I could test with parallel reads. The test script runs in multiple stages. At each stage, the number of dd tasks run concurrently is increased by 2. I did not include all of the test output for brevity. During each stage dd tasks are launched to read from each drive in a round robin fashion until the specified number of tasks for the stage has been reached. Then iostat, vmstat and top are started in the background with 10 second intervals. After five minutes, all of the dd tasks are killed and the iostat, vmstat and top output is parsed in order to report the following: CPU consumption - sy - aggregate kernel mode CPU consumption from vmstat output. The value doesn't tend to fluctuate much so I just grab the highest value. Each sample is averaged over 10 seconds - dd_cpu - for all of the dd tasks averaged across the top samples since there is a lot of variation. Throughput - in Kbytes - Command is iostat -x -d 10 -g total This first test performs reads using O_DIRECT in order to show the maximum throughput that can be obtained using these drives. It also demonstrates how rapidly throughput scales as the number of dd tasks are increased. The dd command for this test looks like this: Command Used: dd iflag=direct if=/d${i}/$n of=/dev/null bs=4M Test #1: Direct IO dd sy dd_cpu throughput 6 0 2.33 14726026.40 10 1 2.95 19954974.80 16 1 2.63 24419689.30 22 1 2.63 25430303.20 28 1 2.91 26026513.20 34 1 2.53 26178618.00 40 1 2.18 26239229.20 46 1 1.91 26250550.40 52 1 1.69 26251845.60 58 1 1.54 26253205.60 64 1 1.43 26253780.80 70 1 1.31 26254154.80 76 1 1.21 26253660.80 82 1 1.12 26254214.80 88 1 1.07 26253770.00 90 1 1.04 26252406.40 Throughput was close to peak with only 22 dd tasks. Very little system CPU was consumed as expected as the drives DMA directly into the user address space when using direct IO. In this next test, the iflag=direct option is removed and we only run the test until the pgscan_kswapd from /proc/vmstat starts to increment. At that point metrics are parsed and reported and the pagecache contents are dropped prior to the next test. Lather, rinse, repeat. Test #2: standard file system IO, no page replacement dd sy dd_cpu throughput 6 2 28.78 5134316.40 10 3 31.40 8051218.40 16 5 34.73 11438106.80 22 7 33.65 14140596.40 28 8 31.24 16393455.20 34 10 29.88 18219463.60 40 11 28.33 19644159.60 46 11 25.05 20802497.60 52 13 26.92 22092370.00 58 13 23.29 22884881.20 64 14 23.12 23452248.80 70 15 22.40 23916468.00 76 16 22.06 24328737.20 82 17 20.97 24718693.20 88 16 18.57 25149404.40 90 16 18.31 25245565.60 Each read has to pause after the buffer in kernel space is populated while those pages are added to the pagecache and copied into the user address space. For this reason, more parallel streams are required to achieve peak throughput. The copy operation consumes substantially more CPU than direct IO as expected. The next test measures throughput after kswapd starts running. This is the same test only we wait for kswapd to wake up before we start collecting metrics. The script actually keeps track of a few things that were not mentioned earlier. It tracks direct reclaims and page scans by watching the metrics in /proc/vmstat. CPU consumption for kswapd is tracked the same way it is tracked for dd. Since the test is 100% reads, you can assume that the page steal rate for kswapd and direct reclaims is almost identical to the scan rate. Test #3: 1 kswapd thread per node dd sy dd_cpu kswapd0 kswapd1 throughput dr pgscan_kswapd pgscan_direct 10 4 26.07 28.56 27.03 7355924.40 0 459316976 0 16 7 34.94 69.33 69.66 10867895.20 0 872661643 0 22 10 36.03 93.99 99.33 13130613.60 489 1037654473 11268334 28 10 30.34 95.90 98.60 14601509.60 671 1182591373 15429142 34 14 34.77 97.50 99.23 16468012.00 10850 1069005644 249839515 40 17 36.32 91.49 97.11 17335987.60 18903 975417728 434467710 46 19 38.40 90.54 91.61 17705394.40 25369 855737040 582427973 52 22 40.88 83.97 83.70 17607680.40 31250 709532935 724282458 58 25 40.89 82.19 80.14 17976905.60 35060 657796473 804117540 64 28 41.77 73.49 75.20 18001910.00 39073 561813658 895289337 70 33 45.51 63.78 64.39 17061897.20 44523 379465571 1020726436 76 36 46.95 57.96 60.32 16964459.60 47717 291299464 1093172384 82 39 47.16 55.43 56.16 16949956.00 49479 247071062 1134163008 88 42 47.41 53.75 47.62 16930911.20 51521 195449924 1180442208 90 43 47.18 51.40 50.59 16864428.00 51618 190758156 1183203901 In the previous test where kswapd was not involved, the system-wide kernel mode CPU consumption with 90 dd tasks was 16%. In this test CPU consumption with 90 tasks is at 43%. With 52 cores, and two kswapd tasks (one per NUMA node), kswapd can only be responsible for a little over 4% of the increase. The rest is likely caused by 51,618 direct reclaims that scanned 1.2 billion pages over the five minute time period of the test.

Mark Salyzyn	5cbbeadd5a	BACKPORT: mm: reclaim small amounts of memory when an external fragmentation event occurs ... An external fragmentation event was previously described as When the page allocator fragments memory, it records the event using the mm_page_alloc_extfrag event. If the fallback_order is smaller than a pageblock order (order-9 on 64-bit x86) then it's considered an event that will cause external fragmentation issues in the future. The kernel reduces the probability of such events by increasing the watermark sizes by calling set_recommended_min_free_kbytes early in the lifetime of the system. This works reasonably well in general but if there are enough sparsely populated pageblocks then the problem can still occur as enough memory is free overall and kswapd stays asleep. This patch introduces a watermark_boost_factor sysctl that allows a zone watermark to be temporarily boosted when an external fragmentation causing events occurs. The boosting will stall allocations that would decrease free memory below the boosted low watermark and kswapd is woken if the calling context allows to reclaim an amount of memory relative to the size of the high watermark and the watermark_boost_factor until the boost is cleared. When kswapd finishes, it wakes kcompactd at the pageblock order to clean some of the pageblocks that may have been affected by the fragmentation event. kswapd avoids any writeback, slab shrinkage and swap from reclaim context during this operation to avoid excessive system disruption in the name of fragmentation avoidance. Care is taken so that kswapd will do normal reclaim work if the system is really low on memory. This was evaluated using the same workloads as "mm, page_alloc: Spread allocations across zones before introducing fragmentation". 1-socket Skylake machine config-global-dhp__workload_thpfioscale XFS (no special madvise) 4 fio threads, 1 THP allocating thread -------------------------------------- 4.20-rc3 extfrag events < order 9: 804694 4.20-rc3+patch: 408912 (49% reduction) 4.20-rc3+patch1-4: 18421 (98% reduction) 4.20.0-rc3 4.20.0-rc3 lowzone-v5r8 boost-v5r8 Amean fault-base-1 653.58 ( 0.00%) 652.71 ( 0.13%) Amean fault-huge-1 0.00 ( 0.00%) 178.93 * -99.00%* 4.20.0-rc3 4.20.0-rc3 lowzone-v5r8 boost-v5r8 Percentage huge-1 0.00 ( 0.00%) 5.12 ( 100.00%) Note that external fragmentation causing events are massively reduced by this path whether in comparison to the previous kernel or the vanilla kernel.

As before, the high THP allocation success rate does mean the system is under a lot of pressure. However, as the fragmentation events are reduced, it would be expected that the long-term allocation success rate would be higher.

Susheel Khiani	d6f731ef20	mm: Update is_vmalloc_addr to account for vmalloc savings ... is_vmalloc_addr currently assumes that all vmalloc addresses exist between VMALLOC_START and VMALLOC_END. This may not be the case when interleaving vmalloc and lowmem. Update the is_vmalloc_addr to properly check for this. Correspondingly we need to ensure that VMALLOC_TOTAL accounts for all the vmalloc regions when CONFIG_ENABLE_VMALLOC_SAVING is enabled.

Joel Fernandes	b3ddf584b0	ANDROID: mm: Throttle rss_stat tracepoint ... Previously we were throttling rss_stat tracepoint by checking for 512KB boundary cross over. We removed that because upstream suggested eBPF or other ways. However right now, we don't have support for those. Let us re introduce the patch to throttle and avoid large number of events which are causing data loss.

Joel Fernandes	23727eb130	UPSTREAM: rss_stat: Add support to detect RSS updates of external mm ... When a process updates the RSS of a different process, the rss_stat tracepoint appears in the context of the process doing the update. This can confuse userspace that the RSS of process doing the update is updated, while in reality a different process's RSS was updated. This issue happens in reclaim paths such as with direct reclaim or background reclaim. This patch adds more information to the tracepoint about whether the mm being updated belongs to the current process's context (curr field). We also include a hash of the mm pointer so that the process who the mm belongs to can be uniquely identified (mm_id field). Also vsprintf.c is refactored a bit to allow reuse of hashing code.

Joel Fernandes (Google)	4f1a044874	UPSTREAM: mm: emit tracepoint when RSS changes ... Useful to track how RSS is changing per TGID to detect spikes in RSS and memory hogs. Several Android teams have been using this patch in various kernel trees for half a year now. Many reported to me it is really useful so I'm posting it upstream. Initial patch developed by Tim Murray. Changes I made from original patch: o Prevent any additional space consumed by mm_struct. Regarding the fact that the RSS may change too often thus flooding the traces - note that, there is some "hysterisis" with this already. That is - We update the counter only if we receive 64 page faults due to SPLIT_RSS_ACCOUNTING. However, during zapping or copying of pte range, the RSS is updated immediately which can become noisy/flooding. In a previous discussion, we agreed that BPF or ftrace can be used to rate limit the signal if this becomes an issue. Also note that I added wrappers to trace_rss_stat to prevent compiler errors where linux/mm.h is included from tracing code, causing errors such as: CC kernel/trace/power-traces.o In file included from ./include/trace/define_trace.h:102, from ./include/trace/events/kmem.h:342, from ./include/linux/mm.h:31, from ./include/linux/ring_buffer.h:5, from ./include/linux/trace_events.h:6, from ./include/trace/events/power.h:12, from kernel/trace/power-traces.c:15: ./include/trace/trace_events.h:113:22: error: field ‘ent’ has incomplete type struct trace_entry ent; \ Change-Id: I26e72db29ec89a305c29a50159279339067f4983 Link: http://lore.kernel.org/r/20190903200905.198642-1-joel@joelfernandes.org Acked-by: Michal Hocko <mhocko@suse.com> Co-developed-by: Tim Murray <timmurray@google.com> Signed-off-by: Tim Murray <timmurray@google.com> Signed-off-by: Joel Fernandes (Google) <joel@joelfernandes.org> Signed-off-by: Joel Fernandes <joelaf@google.com>	2019-11-18 13:58:03 -05:00

Yang Shi	2686f71fdc	mm: thp: handle page cache THP correctly in PageTransCompoundMap ... commit 169226f7e0d275c1879551f37484ef6683579a5c upstream. We have a usecase to use tmpfs as QEMU memory backend and we would like to take the advantage of THP as well. But, our test shows the EPT is not PMD mapped even though the underlying THP are PMD mapped on host. The number showed by /sys/kernel/debug/kvm/largepage is much less than the number of PMD mapped shmem pages as the below: 7f2778200000-7f2878200000 rw-s 00000000 00:14 262232 /dev/shm/qemu_back_mem.mem.Hz2hSf (deleted) Size: 4194304 kB [snip] AnonHugePages: 0 kB ShmemPmdMapped: 579584 kB [snip] Locked: 0 kB cat /sys/kernel/debug/kvm/largepages 12 And some benchmarks do worse than with anonymous THPs. By digging into the code we figured out that commit 127393fbe5 ("mm: thp: kvm: fix memory corruption in KVM with THP enabled") checks if there is a single PTE mapping on the page for anonymous THP when setting up EPT map. But the _mapcount < 0 check doesn't work for page cache THP since every subpage of page cache THP would get _mapcount inc'ed once it is PMD mapped, so PageTransCompoundMap() always returns false for page cache THP. This would prevent KVM from setting up PMD mapped EPT entry. So we need handle page cache THP correctly. However, when page cache THP's PMD gets split, kernel just remove the map instead of setting up PTE map like what anonymous THP does. Before KVM calls get_user_pages() the subpages may get PTE mapped even though it is still a THP since the page cache THP may be mapped by other processes at the mean time. Checking its _mapcount and whether the THP has PTE mapped or not. Although this may report some false negative cases (PTE mapped by other processes), it looks not trivial to make this accurate. With this fix /sys/kernel/debug/kvm/largepage would show reasonable pages are PMD mapped by EPT as the below: 7fbeaee00000-7fbfaee00000 rw-s 00000000 00:14 275464 /dev/shm/qemu_back_mem.mem.SKUvat (deleted) Size: 4194304 kB [snip] AnonHugePages: 0 kB ShmemPmdMapped: 557056 kB [snip] Locked: 0 kB cat /sys/kernel/debug/kvm/largepages 271 And the benchmarks are as same as anonymous THPs.

Andrey Konovalov	9d63092417	UPSTREAM: uaccess: add noop untagged_addr definition ... (Upstream commit d93445225cd3c8eb0bf1350c04875576428b45b4). Architectures that support memory tagging have a need to perform untagging (stripping the tag) in various parts of the kernel. This patch adds an untagged_addr() macro, which is defined as noop for architectures that do not support memory tagging. The oncoming patch series will define it at least for sparc64 and arm64.

Andrey Konovalov	be21fa3044	UPSTREAM: kasan, mm, arm64: tag non slab memory allocated via pagealloc ... (Upstream commit 2813b9c0296259fb11e75c839bab2d958ba4f96c). Tag-based KASAN doesn't check memory accesses through pointers tagged with 0xff. When page_address is used to get pointer to memory that corresponds to some page, the tag of the resulting pointer gets set to 0xff, even though the allocated memory might have been tagged differently. For slab pages it's impossible to recover the correct tag to return from page_address, since the page might contain multiple slab objects tagged with different values, and we can't know in advance which one of them is going to get accessed. For non slab pages however, we can recover the tag in page_address, since the whole page was marked with the same tag. This patch adds tagging to non slab memory allocated with pagealloc. To set the tag of the pointer returned from page_address, the tag gets stored to page->flags when the memory gets allocated.

Alexander Potapenko	a5587d8fce	UPSTREAM: mm: security: introduce init_on_alloc=1 and init_on_free=1 boot options ... Upstream commit 6471384af2a6 ("mm: security: introduce init_on_alloc=1 and init_on_free=1 boot options"). Patch series "add init_on_alloc/init_on_free boot options", v10. Provide init_on_alloc and init_on_free boot options. These are aimed at preventing possible information leaks and making the control-flow bugs that depend on uninitialized values more deterministic. Enabling either of the options guarantees that the memory returned by the page allocator and SL[AU]B is initialized with zeroes. SLOB allocator isn't supported at the moment, as its emulation of kmem caches complicates handling of SLAB_TYPESAFE_BY_RCU caches correctly. Enabling init_on_free also guarantees that pages and heap objects are initialized right after they're freed, so it won't be possible to access stale data by using a dangling pointer. As suggested by Michal Hocko, right now we don't let the heap users to disable initialization for certain allocations. There's not enough evidence that doing so can speed up real-life cases, and introducing ways to opt-out may result in things going out of control. This patch (of 2): The new options are needed to prevent possible information leaks and make control-flow bugs that depend on uninitialized values more deterministic. This is expected to be on-by-default on Android and Chrome OS. And it gives the opportunity for anyone else to use it under distros too via the boot args. (The init_on_free feature is regularly requested by folks where memory forensics is included in their threat models.) init_on_alloc=1 makes the kernel initialize newly allocated pages and heap objects with zeroes. Initialization is done at allocation time at the places where checks for __GFP_ZERO are performed. init_on_free=1 makes the kernel initialize freed pages and heap objects with zeroes upon their deletion. This helps to ensure sensitive data doesn't leak via use-after-free accesses. Both init_on_alloc=1 and init_on_free=1 guarantee that the allocator returns zeroed memory. The two exceptions are slab caches with constructors and SLAB_TYPESAFE_BY_RCU flag. Those are never zero-initialized to preserve their semantics. Both init_on_alloc and init_on_free default to zero, but those defaults can be overridden with CONFIG_INIT_ON_ALLOC_DEFAULT_ON and CONFIG_INIT_ON_FREE_DEFAULT_ON. If either SLUB poisoning or page poisoning is enabled, those options take precedence over init_on_alloc and init_on_free: initialization is only applied to unpoisoned allocations. Slowdown for the new features compared to init_on_free=0, init_on_alloc=0: hackbench, init_on_free=1: +7.62% sys time (st.err 0.74%) hackbench, init_on_alloc=1: +7.75% sys time (st.err 2.14%) Linux build with -j12, init_on_free=1: +8.38% wall time (st.err 0.39%) Linux build with -j12, init_on_free=1: +24.42% sys time (st.err 0.52%) Linux build with -j12, init_on_alloc=1: -0.13% wall time (st.err 0.42%) Linux build with -j12, init_on_alloc=1: +0.57% sys time (st.err 0.40%) The slowdown for init_on_free=0, init_on_alloc=0 compared to the baseline is within the standard error. The new features are also going to pave the way for hardware memory tagging (e.g. arm64's MTE), which will require both on_alloc and on_free hooks to set the tags for heap objects. With MTE, tagging will have the same cost as memory initialization. Although init_on_free is rather costly, there are paranoid use-cases where in-memory data lifetime is desired to be minimized. There are various arguments for/against the realism of the associated threat models, but given that we'll need the infrastructure for MTE anyway, and there are people who want wipe-on-free behavior no matter what the performance cost, it seems reasonable to include it in this series.

Mel Gorman	68809fdd57	mm: reclaim small amounts of memory when an external fragmentation event occurs ... An external fragmentation event was previously described as When the page allocator fragments memory, it records the event using the mm_page_alloc_extfrag event. If the fallback_order is smaller than a pageblock order (order-9 on 64-bit x86) then it's considered an event that will cause external fragmentation issues in the future. The kernel reduces the probability of such events by increasing the watermark sizes by calling set_recommended_min_free_kbytes early in the lifetime of the system. This works reasonably well in general but if there are enough sparsely populated pageblocks then the problem can still occur as enough memory is free overall and kswapd stays asleep. This patch introduces a watermark_boost_factor sysctl that allows a zone watermark to be temporarily boosted when an external fragmentation causing events occurs. The boosting will stall allocations that would decrease free memory below the boosted low watermark and kswapd is woken if the calling context allows to reclaim an amount of memory relative to the size of the high watermark and the watermark_boost_factor until the boost is cleared. When kswapd finishes, it wakes kcompactd at the pageblock order to clean some of the pageblocks that may have been affected by the fragmentation event. kswapd avoids any writeback, slab shrinkage and swap from reclaim context during this operation to avoid excessive system disruption in the name of fragmentation avoidance. Care is taken so that kswapd will do normal reclaim work if the system is really low on memory. This was evaluated using the same workloads as "mm, page_alloc: Spread allocations across zones before introducing fragmentation". 1-socket Skylake machine config-global-dhp__workload_thpfioscale XFS (no special madvise) 4 fio threads, 1 THP allocating thread -------------------------------------- 4.20-rc3 extfrag events < order 9: 804694 4.20-rc3+patch: 408912 (49% reduction) 4.20-rc3+patch1-4: 18421 (98% reduction) 4.20.0-rc3 4.20.0-rc3 lowzone-v5r8 boost-v5r8 Amean fault-base-1 653.58 ( 0.00%) 652.71 ( 0.13%) Amean fault-huge-1 0.00 ( 0.00%) 178.93 * -99.00%* 4.20.0-rc3 4.20.0-rc3 lowzone-v5r8 boost-v5r8 Percentage huge-1 0.00 ( 0.00%) 5.12 ( 100.00%) Note that external fragmentation causing events are massively reduced by this path whether in comparison to the previous kernel or the vanilla kernel.

Linus Torvalds	0612cae7ec	mm: add 'try_get_page()' helper function ... commit 88b1a17dfc3ed7728316478fae0f5ad508f50397 upstream. This is the same as the traditional 'get_page()' function, but instead of unconditionally incrementing the reference count of the page, it only does so if the count was "safe". It returns whether the reference count was incremented (and is marked __must_check, since the caller obviously has to be aware of it). Also like 'get_page()', you can't use this function unless you already had a reference to the page. The intent is that you can use this exactly like get_page(), but in situations where you want to limit the maximum reference count. The code currently does an unconditional WARN_ON_ONCE() if we ever hit the reference count issues (either zero or negative), as a notification that the conditional non-increment actually happened. NOTE! The count access for the "safety" check is inherently racy, but that doesn't matter since the buffer we use is basically half the range of the reference count (ie we look at the sign of the count).

Linus Torvalds	9f6da5fd05	mm: make page ref count overflow check tighter and more explicit ... commit f958d7b528b1b40c44cfda5eabe2d82760d868c3 upstream. We have a VM_BUG_ON() to check that the page reference count doesn't underflow (or get close to overflow) by checking the sign of the count. That's all fine, but we actually want to allow people to use a "get page ref unless it's already very high" helper function, and we want that one to use the sign of the page ref (without triggering this VM_BUG_ON). Change the VM_BUG_ON to only check for small underflows (or _very_ close to overflowing), and ignore overflows which have strayed into negative territory.

Laurent Dufour	7d2d0af315	mm: speculative page fault handler return VMA ... When the speculative page fault handler is returning VM_RETRY, there is a chance that VMA fetched without grabbing the mmap_sem can be reused by the legacy page fault handler. By reusing it, we avoid calling find_vma() again. To achieve, that we must ensure that the VMA structure will not be freed in our back. This is done by getting the reference on it (get_vma()) and by assuming that the caller will call the new service can_reuse_spf_vma() once it has grabbed the mmap_sem. can_reuse_spf_vma() is first checking that the VMA is still in the RB tree , and then that the VMA's boundaries matched the passed address and release the reference on the VMA so that it can be freed if needed. In the case the VMA is freed, can_reuse_spf_vma() will have returned false as the VMA is no more in the RB tree. In the architecture page fault handler, the call to the new service reuse_spf_or_find_vma() should be made in place of find_vma(), this will handle the check on the spf_vma and if needed call find_vma().

The not holding of mmap_sem means we can race against VMA change/removal and page-table destruction. We use the SRCU VMA freeing to keep the VMA around. We use the VMA seqcount to detect change (including umapping / page-table deletion) and we use gup_fast() style page-table walking to deal with page-table races. Once we've obtained the page and are ready to update the PTE, we validate if the state we started the fault with is still valid, if not, we'll fail the fault with VM_FAULT_RETRY, otherwise we update the PTE and we're done.

Laurent Dufour	3f31f748a8	mm: protect mm_rb tree with a rwlock ... This change is inspired by the Peter's proposal patch [1] which was protecting the VMA using SRCU. Unfortunately, SRCU is not scaling well in that particular case, and it is introducing major performance degradation due to excessive scheduling operations. To allow access to the mm_rb tree without grabbing the mmap_sem, this patch is protecting it access using a rwlock. As the mm_rb tree is a O(log n) search it is safe to protect it using such a lock. The VMA cache is not protected by the new rwlock and it should not be used without holding the mmap_sem. To allow the picked VMA structure to be used once the rwlock is released, a use count is added to the VMA structure. When the VMA is allocated it is set to 1. Each time the VMA is picked with the rwlock held its use count is incremented. Each time the VMA is released it is decremented. When the use count hits zero, this means that the VMA is no more used and should be freed. This patch is preparing for 2 kind of VMA access : - as usual, under the control of the mmap_sem, - without holding the mmap_sem for the speculative page fault handler. Access done under the control the mmap_sem doesn't require to grab the rwlock to protect read access to the mm_rb tree, but access in write must be done under the protection of the rwlock too. This affects inserting and removing of elements in the RB tree. The patch is introducing 2 new functions: - vma_get() to find a VMA based on an address by holding the new rwlock. - vma_put() to release the VMA when its no more used. These services are designed to be used when access are made to the RB tree without holding the mmap_sem. When a VMA is removed from the RB tree, its vma->vm_rb field is cleared and we rely on the WMB done when releasing the rwlock to serialize the write with the RMB done in a later patch to check for the VMA's validity. When free_vma is called, the file associated with the VMA is closed immediately, but the policy and the file structure remained in used until the VMA's use count reach 0, which may happens later when exiting an in progress speculative page fault.

Laurent Dufour	d91303f0a1	mm: protect mremap() against SPF hanlder ... If a thread is remapping an area while another one is faulting on the destination area, the SPF handler may fetch the vma from the RB tree before the pte has been moved by the other thread. This means that the moved ptes will overwrite those create by the page fault handler leading to page leaked. CPU 1 CPU2 enter mremap() unmap the dest area copy_vma() Enter speculative page fault handler >> at this time the dest area is present in the RB tree fetch the vma matching dest area create a pte as the VMA matched Exit the SPF handler <data written in the new page> move_ptes() > it is assumed that the dest area is empty, > the move ptes overwrite the page mapped by the CPU2. To prevent that, when the VMA matching the dest area is extended or created by copy_vma(), it should be marked as non available to the SPF handler. The usual way to so is to rely on vm_write_begin()/end(). This is already in __vma_adjust() called by copy_vma() (through vma_merge()). But __vma_adjust() is calling vm_write_end() before returning which create a window for another thread. This patch adds a new parameter to vma_merge() which is passed down to vma_adjust(). The assumption is that copy_vma() is returning a vma which should be released by calling vm_raw_write_end() by the callee once the ptes have been moved.

Peter Zijlstra	88a78dc286	mm: VMA sequence count ... Wrap the VMA modifications (vma_adjust/unmap_page_range) with sequence counts such that we can easily test if a VMA is changed. The unmap_page_range() one allows us to make assumptions about page-tables; when we find the seqcount hasn't changed we can assume page-tables are still valid. The flip side is that we cannot distinguish between a vma_adjust() and the unmap_page_range() -- where with the former we could have re-checked the vma bounds against the address.

Laurent Dufour	ead04c98fd	mm: introduce INIT_VMA() ... Some VMA struct fields need to be initialized once the VMA structure is allocated. Currently this only concerns anon_vma_chain field but some other will be added to support the speculative page fault. Instead of spreading the initialization calls all over the code, let's introduce a dedicated inline function.

Laurent Dufour	976415c621	mm: make pte_unmap_same compatible with SPF ... pte_unmap_same() is making the assumption that the page table are still around because the mmap_sem is held. This is no more the case when running a speculative page fault and additional check must be made to ensure that the final page table are still there. This is now done by calling pte_spinlock() to check for the VMA's consistency while locking for the page tables. This is requiring passing a vm_fault structure to pte_unmap_same() which is containing all the needed parameters. As pte_spinlock() may fail in the case of a speculative page fault, if the VMA has been touched in our back, pte_unmap_same() should now return 3 cases : 1. pte are the same (0) 2. pte are different (VM_FAULT_PTNOTSAME) 3. a VMA's changes has been detected (VM_FAULT_RETRY) The case 2 is handled by the introduction of a new VM_FAULT flag named VM_FAULT_PTNOTSAME which is then trapped in cow_user_page(). If VM_FAULT_RETRY is returned, it is passed up to the callers to retry the page fault while holding the mmap_sem.

Vinayak Menon	3aee78b794	mm: make faultaround produce old ptes ... Based on Kirill's patch [1]. Currently, faultaround code produces young pte. This can screw up vmscan behaviour[2], as it makes vmscan think that these pages are hot and not push them out on first round. During sparse file access faultaround gets more pages mapped and all of them are young. Under memory pressure, this makes vmscan swap out anon pages instead, or to drop other page cache pages which otherwise stay resident. Modify faultaround to produce old ptes if sysctl 'want_old_faultaround_pte' is set, so they can easily be reclaimed under memory pressure. This can to some extend defeat the purpose of faultaround on machines without hardware accessed bit as it will not help us with reducing the number of minor page faults. Making the faultaround ptes old results in a unixbench regression for some architectures [3][4]. But on some architectures like arm64 it is not found to cause any regression. unixbench shell8 scores on arm64 v8.2 hardware with CONFIG_ARM64_HW_AFDBM enabled (5 runs min, max, avg): Base: (741,748,744) With this patch: (739,748,743) So by default produce young ptes and provide a sysctl option to make the ptes old.

Martin Schwidefsky	28a3b553dd	mm: add mm_pxd_folded checks to pgtable_bytes accounting functions ... [ Upstream commit 6d212db11947ae5464e4717536ed9faf61c01e86 ] The common mm code calls mm_dec_nr_pmds() and mm_dec_nr_puds() in free_pgtables() if the address range spans a full pud or pmd. If mm_dec_nr_puds/mm_dec_nr_pmds are non-empty due to configuration settings they blindly subtract the size of the pmd or pud table from pgtable_bytes even if the pud or pmd page table layer is folded. Add explicit mm_[pmd|pud]_folded checks to the four pgtable_bytes accounting functions mm_inc_nr_puds, mm_inc_nr_pmds, mm_dec_nr_puds and mm_dec_nr_pmds. As the check for folded page tables can be overwritten by the architecture, this allows to keep a correct pgtable_bytes value for platforms that use a dynamic number of page table levels.

Colin Cross	533e4ed309	ANDROID: mm: add a field to store names for private anonymous memory ... Userspace processes often have multiple allocators that each do anonymous mmaps to get memory. When examining memory usage of individual processes or systems as a whole, it is useful to be able to break down the various heaps that were allocated by each layer and examine their size, RSS, and physical memory usage. This patch adds a user pointer to the shared union in vm_area_struct that points to a null terminated string inside the user process containing a name for the vma. vmas that point to the same address will be merged, but vmas that point to equivalent strings at different addresses will not be merged. Userspace can set the name for a region of memory by calling prctl(PR_SET_VMA, PR_SET_VMA_ANON_NAME, start, len, (unsigned long)name); Setting the name to NULL clears it. The names of named anonymous vmas are shown in /proc/pid/maps as [anon:<name>] and in /proc/pid/smaps in a new "Name" field that is only present for named vmas. If the userspace pointer is no longer valid all or part of the name will be replaced with "<fault>". The idea to store a userspace pointer to reduce the complexity within mm (at the expense of the complexity of reading /proc/pid/mem) came from Dave Hansen. This results in no runtime overhead in the mm subsystem other than comparing the anon_name pointers when considering vma merging. The pointer is stored in a union with fieds that are only used on file-backed mappings, so it does not increase memory usage. Includes fix from Jed Davis <jld@mozilla.com> for typo in prctl_set_vma_anon_name, which could attempt to set the name across two vmas at the same time due to a typo, which might corrupt the vma list. Fix it to use tmp instead of end to limit the name setting to a single vma at a time.
