[PATCH 4.9 01/13] bpf: get rid of pure_initcall dependency to enable jits

by Ben Hutchings

From: Daniel Borkmann <daniel(a)iogearbox.net> commit fa9dd599b4dae841924b022768354cfde9affecb upstream. Having a pure_initcall() callback just to permanently enable BPF JITs under CONFIG_BPF_JIT_ALWAYS_ON is unnecessary and could leave a small race window in future where JIT is still disabled on boot. Since we know about the setting at compilation time anyway, just initialize it properly there. Also consolidate all the individual bpf_jit_enable variables into a single one and move them under one location. Moreover, don't allow for setting unspecified garbage values on them.

[PATCH -stable v4.14] mm/usercopy: use memory range to be accessed for wraparound check

by Kees Cook

From: Prasad Sodagudi <psodagud(a)codeaurora.org> commit 951531691c4bcaa59f56a316e018bc2ff1ddf855 upstream. Currently, when checking to see if accessing n bytes starting at address "ptr" will cause a wraparound in the memory addresses, the check in check_bogus_address() adds an extra byte, which is incorrect, as the range of addresses that will be accessed is [ptr, ptr + (n - 1)]. This can lead to incorrectly detecting a wraparound in the memory address, when trying to read 4 KB from memory that is mapped to the the last possible page in the virtual address space, when in fact, accessing that range of memory would not cause a wraparound to occur. Use the memory range that will actually be accessed when considering if accessing a certain amount of bytes will cause the memory address to wrap around.

[PATCH] arm64: ftrace: Ensure module ftrace trampoline is coherent with I-side

by Will Deacon

The initial support for dynamic ftrace trampolines in modules made use of an indirect branch which loaded its target from the beginning of a special section (e71a4e1bebaf7 ("arm64: ftrace: add support for far branches to dynamic ftrace")). Since no instructions were being patched, no cache maintenance was needed. However, later in be0f272bfc83 ("arm64: ftrace: emit ftrace-mod.o contents through code") this code was reworked to output the trampoline instructions directly into the PLT entry but, unfortunately, the necessary cache maintenance was overlooked. Add a call to __flush_icache_range() after writing the new trampoline instructions but before patching in the branch to the trampoline.

[PATCH] blk-mq: remove blk_mq_hw_sysfs_cpus

by Ming Lei

It is reported that sysfs buffer overflow can be triggered in case of too many CPU cores(>841 on 4K PAGE_SIZE) when showing CPUs in blk_mq_hw_sysfs_cpus_show(). This info isn't useful, given users may retrieve the CPU list from sw queue entries under same kobject dir, so far not see any active users. So remove the entry as suggested by Greg.

[PATCH] blk-mq: avoid sysfs buffer overflow by too many CPU cores

by Ming Lei

It is reported that sysfs buffer overflow can be triggered in case of too many CPU cores(>841 on 4K PAGE_SIZE) when showing CPUs in one hctx. So use snprintf for avoiding the potential buffer overflow.

The patch below does not apply to the 4.4-stable tree.

I work with android kernel tree (4.9 & 4.14), and commit be2657752e9e ("mm: memcg: fix use after free in mem_cgroup_iter()") has been merged to the trees.

Manjarres" <isaacm(a)codeaurora.org> Date: Tue, 13 Aug 2019 15:37:37 -0700 Subject: [PATCH] mm/usercopy: use memory range to be accessed for wraparound check Currently, when checking to see if accessing n bytes starting at address "ptr" will cause a wraparound in the memory addresses, the check in check_bogus_address() adds an extra byte, which is incorrect, as the range of addresses that will be accessed is [ptr, ptr + (n - 1)]. This can lead to incorrectly detecting a wraparound in the memory address, when trying to read 4 KB from memory that is mapped to the the last possible page in the virtual address space, when in fact, accessing that range of memory would not cause a wraparound to occur. Use the memory range that will actually be accessed when considering if accessing a certain amount of bytes will cause the memory address to wrap around.

FAILED: patch "[PATCH] mm: mempolicy: make the behavior consistent when" failed to apply to 4.9-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From d883544515aae54842c21730b880172e7894fde9 Mon Sep 17 00:00:00 2001 From: Yang Shi <yang.shi(a)linux.alibaba.com> Date: Tue, 13 Aug 2019 15:37:15 -0700 Subject: [PATCH] mm: mempolicy: make the behavior consistent when MPOL_MF_MOVE* and MPOL_MF_STRICT were specified When both MPOL_MF_MOVE* and MPOL_MF_STRICT was specified, mbind() should try best to migrate misplaced pages, if some of the pages could not be migrated, then return -EIO. There are three different sub-cases: 1. vma is not migratable 2. vma is migratable, but there are unmovable pages 3. vma is migratable, pages are movable, but migrate_pages() fails If #1 happens, kernel would just abort immediately, then return -EIO, after a7f40cfe3b7a ("mm: mempolicy: make mbind() return -EIO when MPOL_MF_STRICT is specified"). If #3 happens, kernel would set policy and migrate pages with best-effort, but won't rollback the migrated pages and reset the policy back. Before that commit, they behaves in the same way. It'd better to keep their behavior consistent. But, rolling back the migrated pages and resetting the policy back sounds not feasible, so just make #1 behave as same as #3. Userspace will know that not everything was successfully migrated (via -EIO), and can take whatever steps it deems necessary - attempt rollback, determine which exact page(s) are violating the policy, etc. Make queue_pages_range() return 1 to indicate there are unmovable pages or vma is not migratable. The #2 is not handled correctly in the current kernel, the following patch will fix it.

This is so rmap_walk() can be used to unmap and migrate the page back to system memory. However, try_to_unmap_one() computes the subpage pointer from a swap pte which computes an invalid page pointer and a kernel panic results such as: BUG: unable to handle page fault for address: ffffea1fffffffc8 Currently, only single pages can be migrated to device private memory so no subpage computation is needed and it can be set to "page".

[PATCH RESEND] mpt3sas: Use 63-bit DMA addressing on SAS35 HBA

by Suganath Prabu

From: Suganath Prabu S <suganath-prabu.subramani(a)broadcom.com> Although SAS3 & SAS3.5 IT HBA controllers support 64-bit DMA addressing, as per hardware design, if DMA able range contains all 64-bits set (0xFFFFFFFF-FFFFFFFF) then it results in a firmware fault. e.g. SGE's start address is 0xFFFFFFFF-FFFF000 and data length is 0x1000 bytes. when HBA tries to DMA the data at 0xFFFFFFFF-FFFFFFFF location then HBA will fault the firmware. Fix: Driver will set 63-bit DMA mask to ensure the above address will not be used.

[PATCH 1/1] usb: chipidea: udc: don't do hardware access if gadget has stopped

by Peter Chen

After _gadget_stop_activity is executed, we can consider the hardware operation for gadget has finished, and the udc can be stopped and enter low power mode. So, any later hardware operations (from usb_ep_ops APIs or usb_gadget_ops APIs) should be considered invalid, any deinitializatons has been covered at _gadget_stop_activity. I meet this problem when I plug out usb cable from PC using mass_storage gadget, my callstack like: vbus interrupt->.vbus_session-> composite_disconnect ->pm_runtime_put_sync(&_gadget->dev), the composite_disconnect will call fsg_disable, but fsg_disable calls usb_ep_disable using async way, there are register accesses for usb_ep_disable. So sometimes, I get system hang due to visit register without clock, sometimes not. The Linux Kernel USB maintainer Alan Stern suggests this kinds of solution. See: http://marc.info/?l=linux-usb&m=138541769810983&w=2.

[PATCH v4 0/5] Fixes for HiSilicon LPC driver and logical PIO code

by John Garry

As reported in [1], the hisi-lpc driver has certain issues in handling logical PIO regions, specifically unregistering regions. This series add a method to unregister a logical PIO region, and fixes up the driver to use them. RCU usage in logical PIO code looks to always have been broken, so that is fixed also. This is not a major fix as the list which RCU protects would be rarely modified. At this point, there are still separate ongoing discussions about how to stop the logical PIO and PCI host bridge code leaking ranges, as in [2], which I haven't had a chance to look at recently. Hopefully this series can go through the arm soc tree and the maintainers have no issue with that. I'm talking specifically about the logical PIO code, which went through PCI tree on only previous upstreaming.

patch "tty/serial: atmel: reschedule TX after RX was started" added to tty-next

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled tty/serial: atmel: reschedule TX after RX was started to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-next branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From 1bc102260d278de0af89c58536f4bbabd2ef28be Mon Sep 17 00:00:00 2001 From: Razvan Stefanescu <razvan.stefanescu(a)microchip.com> Date: Tue, 13 Aug 2019 10:40:25 +0300 Subject: tty/serial: atmel: reschedule TX after RX was started When half-duplex RS485 communication is used, after RX is started, TX tasklet still needs to be scheduled tasklet. This avoids console freezing when more data is to be transmitted, if the serial communication is not closed.

[PATCH v3 1/2] rtw88: pci: Rearrange the memory usage for skb in RX ISR

by Jian-Hong Pan

Testing with RTL8822BE hardware, when available memory is low, we frequently see a kernel panic and system freeze. First, rtw_pci_rx_isr encounters a memory allocation failure (trimmed): rx routine starvation WARNING: CPU: 7 PID: 9871 at drivers/net/wireless/realtek/rtw88/pci.c:822 rtw_pci_rx_isr.constprop.25+0x35a/0x370 [rtwpci] [ 2356.580313] RIP: 0010:rtw_pci_rx_isr.constprop.25+0x35a/0x370 [rtwpci] Then we see a variety of different error conditions and kernel panics, such as this one (trimmed): rtw_pci 0000:02:00.0: pci bus timeout, check dma status skbuff: skb_over_panic: text:00000000091b6e66 len:415 put:415 head:00000000d2880c6f data:000000007a02b1ea tail:0x1df end:0xc0 dev:<NULL> ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:105! invalid opcode: 0000 [#1] SMP NOPTI RIP: 0010:skb_panic+0x43/0x45 When skb allocation fails and the "rx routine starvation" is hit, the function returns immediately without updating the RX ring. At this point, the RX ring may continue referencing an old skb which was already handed off to ieee80211_rx_irqsafe(). When it comes to be used again, bad things happen. This patch allocates a new, data-sized skb first in RX ISR. After copying the data in, we pass it to the upper layers. However, if skb allocation fails, we effectively drop the frame. In both cases, the original, full size ring skb is reused. In addition, by fixing the kernel crash, the RX routine should now generally behave better under low memory conditions.

[merged] mm-vmscan-do-not-special-case-slab-reclaim-when-watermarks-are-boosted.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm, vmscan: do not special-case slab reclaim when watermarks are boosted has been removed from the -mm tree. Its filename was mm-vmscan-do-not-special-case-slab-reclaim-when-watermarks-are-boosted.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Mel Gorman <mgorman(a)techsingularity.net> Subject: mm, vmscan: do not special-case slab reclaim when watermarks are boosted Dave Chinner reported a problem pointing a finger at commit 1c30844d2dfe ("mm: reclaim small amounts of memory when an external fragmentation event occurs"). The report is extensive (see https://lore.kernel.org/linux-mm/20190807091858.2857-1-david@fromorbit.com/) and it's worth recording the most relevant parts (colorful language and typos included). When running a simple, steady state 4kB file creation test to simulate extracting tarballs larger than memory full of small files into the filesystem, I noticed that once memory fills up the cache balance goes to hell. The workload is creating one dirty cached inode for every dirty page, both of which should require a single IO each to clean and reclaim, and creation of inodes is throttled by the rate at which dirty writeback runs at (via balance dirty pages). Hence the ingest rate of new cached inodes and page cache pages is identical and steady. As a result, memory reclaim should quickly find a steady balance between page cache and inode caches. The moment memory fills, the page cache is reclaimed at a much faster rate than the inode cache, and evidence suggests that the inode cache shrinker is not being called when large batches of pages are being reclaimed. In roughly the same time period that it takes to fill memory with 50% pages and 50% slab caches, memory reclaim reduces the page cache down to just dirty pages and slab caches fill the entirety of memory. The LRU is largely full of dirty pages, and we're getting spikes of random writeback from memory reclaim so it's all going to shit. Behaviour never recovers, the page cache remains pinned at just dirty pages, and nothing I could tune would make any difference. vfs_cache_pressure makes no difference - I would set it so high it should trim the entire inode caches in a single pass, yet it didn't do anything. It was clear from tracing and live telemetry that the shrinkers were pretty much not running except when there was absolutely no memory free at all, and then they did the minimum necessary to free memory to make progress. So I went looking at the code, trying to find places where pages got reclaimed and the shrinkers weren't called. There's only one - kswapd doing boosted reclaim as per commit 1c30844d2dfe ("mm: reclaim small amounts of memory when an external fragmentation event occurs"). The watermark boosting introduced by the commit is triggered in response to an allocation "fragmentation event". The boosting was not intended to target THP specifically and triggers even if THP is disabled. However, with Dave's perfectly reasonable workload, fragmentation events can be very common given the ratio of slab to page cache allocations so boosting remains active for long periods of time. As high-order allocations might use compaction and compaction cannot move slab pages the decision was made in the commit to special-case kswapd when watermarks are boosted -- kswapd avoids reclaiming slab as reclaiming slab does not directly help compaction. As Dave notes, this decision means that slab can be artificially protected for long periods of time and messes up the balance with slab and page caches. Removing the special casing can still indirectly help avoid fragmentation by avoiding fragmentation-causing events due to slab allocation as pages from a slab pageblock will have some slab objects freed. Furthermore, with the special casing, reclaim behaviour is unpredictable as kswapd sometimes examines slab and sometimes does not in a manner that is tricky to tune or analyse. This patch removes the special casing. The downside is that this is not a universal performance win. Some benchmarks that depend on the residency of data when rereading metadata may see a regression when slab reclaim is restored to its original behaviour. Similarly, some benchmarks that only read-once or write-once may perform better when page reclaim is too aggressive. The primary upside is that slab shrinker is less surprising (arguably more sane but that's a matter of opinion), behaves consistently regardless of the fragmentation state of the system and properly obeys VM sysctls. A fsmark benchmark configuration was constructed similar to what Dave reported and is codified by the mmtest configuration config-io-fsmark-small-file-stream. It was evaluated on a 1-socket machine to avoid dealing with NUMA-related issues and the timing of reclaim. The storage was an SSD Samsung Evo and a fresh trimmed XFS filesystem was used for the test data. This is not an exact replication of Dave's setup. The configuration scales its parameters depending on the memory size of the SUT to behave similarly across machines. The parameters mean the first sample reported by fs_mark is using 50% of RAM which will barely be throttled and look like a big outlier. Dave used fake NUMA to have multiple kswapd instances which I didn't replicate. Finally, the number of iterations differ from Dave's test as the target disk was not large enough. While not identical, it should be representative. fsmark 5.3.0-rc3 5.3.0-rc3 vanilla shrinker-v1r1 Min 1-files/sec 4444.80 ( 0.00%) 4765.60 ( 7.22%) 1st-qrtle 1-files/sec 5005.10 ( 0.00%) 5091.70 ( 1.73%) 2nd-qrtle 1-files/sec 4917.80 ( 0.00%) 4855.60 ( -1.26%) 3rd-qrtle 1-files/sec 4667.40 ( 0.00%) 4831.20 ( 3.51%) Max-1 1-files/sec 11421.50 ( 0.00%) 9999.30 ( -12.45%) Max-5 1-files/sec 11421.50 ( 0.00%) 9999.30 ( -12.45%) Max-10 1-files/sec 11421.50 ( 0.00%) 9999.30 ( -12.45%) Max-90 1-files/sec 4649.60 ( 0.00%) 4780.70 ( 2.82%) Max-95 1-files/sec 4491.00 ( 0.00%) 4768.20 ( 6.17%) Max-99 1-files/sec 4491.00 ( 0.00%) 4768.20 ( 6.17%) Max 1-files/sec 11421.50 ( 0.00%) 9999.30 ( -12.45%) Hmean 1-files/sec 5004.75 ( 0.00%) 5075.96 ( 1.42%) Stddev 1-files/sec 1778.70 ( 0.00%) 1369.66 ( 23.00%) CoeffVar 1-files/sec 33.70 ( 0.00%) 26.05 ( 22.71%) BHmean-99 1-files/sec 5053.72 ( 0.00%) 5101.52 ( 0.95%) BHmean-95 1-files/sec 5053.72 ( 0.00%) 5101.52 ( 0.95%) BHmean-90 1-files/sec 5107.05 ( 0.00%) 5131.41 ( 0.48%) BHmean-75 1-files/sec 5208.45 ( 0.00%) 5206.68 ( -0.03%) BHmean-50 1-files/sec 5405.53 ( 0.00%) 5381.62 ( -0.44%) BHmean-25 1-files/sec 6179.75 ( 0.00%) 6095.14 ( -1.37%) 5.3.0-rc3 5.3.0-rc3 vanillashrinker-v1r1 Duration User 501.82 497.29 Duration System 4401.44 4424.08 Duration Elapsed 8124.76 8358.05 This is showing a slight skew for the max result representing a large outlier for the 1st, 2nd and 3rd quartile are similar indicating that the bulk of the results show little difference. Note that an earlier version of the fsmark configuration showed a regression but that included more samples taken while memory was still filling. Note that the elapsed time is higher. Part of this is that the configuration included time to delete all the test files when the test completes -- the test automation handles the possibility of testing fsmark with multiple thread counts. Without the patch, many of these objects would be memory resident which is part of what the patch is addressing. There are other important observations that justify the patch. 1. With the vanilla kernel, the number of dirty pages in the system is very low for much of the test. With this patch, dirty pages is generally kept at 10% which matches vm.dirty_background_ratio which is normal expected historical behaviour. 2. With the vanilla kernel, the ratio of Slab/Pagecache is close to 0.95 for much of the test i.e. Slab is being left alone and dominating memory consumption. With the patch applied, the ratio varies between 0.35 and 0.45 with the bulk of the measured ratios roughly half way between those values. This is a different balance to what Dave reported but it was at least consistent. 3. Slabs are scanned throughout the entire test with the patch applied. The vanille kernel has periods with no scan activity and then relatively massive spikes. 4. Without the patch, kswapd scan rates are very variable. With the patch, the scan rates remain quite stead. 4. Overall vmstats are closer to normal expectations 5.3.0-rc3 5.3.0-rc3 vanilla shrinker-v1r1 Ops Direct pages scanned 99388.00 328410.00 Ops Kswapd pages scanned 45382917.00 33451026.00 Ops Kswapd pages reclaimed 30869570.00 25239655.00 Ops Direct pages reclaimed 74131.00 5830.00 Ops Kswapd efficiency % 68.02 75.45 Ops Kswapd velocity 5585.75 4002.25 Ops Page reclaim immediate 1179721.00 430927.00 Ops Slabs scanned 62367361.00 73581394.00 Ops Direct inode steals 2103.00 1002.00 Ops Kswapd inode steals 570180.00 5183206.00 o Vanilla kernel is hitting direct reclaim more frequently, not very much in absolute terms but the fact the patch reduces it is interesting o "Page reclaim immediate" in the vanilla kernel indicates dirty pages are being encountered at the tail of the LRU. This is generally bad and means in this case that the LRU is not long enough for dirty pages to be cleaned by the background flush in time. This is much reduced by the patch. o With the patch, kswapd is reclaiming 10 times more slab pages than with the vanilla kernel. This is indicative of the watermark boosting over-protecting slab A more complete set of tests were run that were part of the basis for introducing boosting and while there are some differences, they are well within tolerances. Bottom line, the special casing kswapd to avoid slab behaviour is unpredictable and can lead to abnormal results for normal workloads. This patch restores the expected behaviour that slab and page cache is balanced consistently for a workload with a steady allocation ratio of slab/pagecache pages. It also means that if there are workloads that favour the preservation of slab over pagecache that it can be tuned via vm.vfs_cache_pressure where as the vanilla kernel effectively ignores the parameter when boosting is active.

When seeking to a record boundary, the next record is correctly returned. This bug was introduced by a recent patch (identified below). Before that patch, seq_read() would increment m->index when the last of the buffer was returned (m->count == 0). After that patch, we rely on ->next to increment m->index after filling the buffer - but there was one place where that didn't happen.

When calling mbind(), it would scan the vma to queue the pages for migration to the new node. It would split any huge page since 4.9 doesn't support THP migration, however, the packet tx ring compound pages are not THP and even not movable. So, the above bug is triggered. However, the later kernel is not hit by this issue due to d44d363f65780f2ac2 ("mm: don't assume anonymous pages have SwapBacked flag"), which just removes the PageSwapBacked check for a different reason. But, there is a deeper issue. According to the semantic of mbind(), it should return -EIO if MPOL_MF_MOVE or MPOL_MF_MOVE_ALL was specified and MPOL_MF_STRICT was also specified, but the kernel was unable to move all existing pages in the range. The tx ring of the packet socket is definitely not movable, however, mbind() returns success for this case. Although the most socket file associates with non-movable pages, but XDP may have movable pages from gup. So, it sounds not fine to just check the underlying file type of vma in vma_migratable(). Change migrate_page_add() to check if the page is movable or not, if it is unmovable, just return -EIO. But do not abort pte walk immediately, since there may be pages off LRU temporarily. We should migrate other pages if MPOL_MF_MOVE* is specified. Set has_unmovable flag if some paged could not be not moved, then return -EIO for mbind() eventually. With this change the above test would return -EIO as expected.

[merged] mm-mempolicy-make-the-behavior-consistent-when-mpol_mf_move-and-mpol_mf_strict-were-specified.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm: mempolicy: make the behavior consistent when MPOL_MF_MOVE* and MPOL_MF_STRICT were specified has been removed from the -mm tree. Its filename was mm-mempolicy-make-the-behavior-consistent-when-mpol_mf_move-and-mpol_mf_strict-were-specified.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Yang Shi <yang.shi(a)linux.alibaba.com> Subject: mm: mempolicy: make the behavior consistent when MPOL_MF_MOVE* and MPOL_MF_STRICT were specified When both MPOL_MF_MOVE* and MPOL_MF_STRICT was specified, mbind() should try best to migrate misplaced pages, if some of the pages could not be migrated, then return -EIO. There are three different sub-cases: 1. vma is not migratable 2. vma is migratable, but there are unmovable pages 3. vma is migratable, pages are movable, but migrate_pages() fails If #1 happens, kernel would just abort immediately, then return -EIO, after a7f40cfe3b7ada ("mm: mempolicy: make mbind() return -EIO when MPOL_MF_STRICT is specified"). If #3 happens, kernel would set policy and migrate pages with best-effort, but won't rollback the migrated pages and reset the policy back. Before that commit, they behaves in the same way. It'd better to keep their behavior consistent. But, rolling back the migrated pages and resetting the policy back sounds not feasible, so just make #1 behave as same as #3. Userspace will know that not everything was successfully migrated (via -EIO), and can take whatever steps it deems necessary - attempt rollback, determine which exact page(s) are violating the policy, etc. Make queue_pages_range() return 1 to indicate there are unmovable pages or vma is not migratable. The #2 is not handled correctly in the current kernel, the following patch will fix it.

[merged] mm-hmm-fix-zone_device-anon-page-mapping-reuse.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/hmm: fix ZONE_DEVICE anon page mapping reuse has been removed from the -mm tree. Its filename was mm-hmm-fix-zone_device-anon-page-mapping-reuse.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Ralph Campbell <rcampbell(a)nvidia.com> Subject: mm/hmm: fix ZONE_DEVICE anon page mapping reuse When a ZONE_DEVICE private page is freed, the page->mapping field can be set. If this page is reused as an anonymous page, the previous value can prevent the page from being inserted into the CPU's anon rmap table. For example, when migrating a pte_none() page to device memory: migrate_vma(ops, vma, start, end, src, dst, private) migrate_vma_collect() src[] = MIGRATE_PFN_MIGRATE migrate_vma_prepare() /* no page to lock or isolate so OK */ migrate_vma_unmap() /* no page to unmap so OK */ ops->alloc_and_copy() /* driver allocates ZONE_DEVICE page for dst[] */ migrate_vma_pages() migrate_vma_insert_page() page_add_new_anon_rmap() __page_set_anon_rmap() /* This check sees the page's stale mapping field */ if (PageAnon(page)) return /* page->mapping is not updated */ The result is that the migration appears to succeed but a subsequent CPU fault will be unable to migrate the page back to system memory or worse. Clear the page->mapping field when freeing the ZONE_DEVICE page so stale pointer data doesn't affect future page use.

[PATCH 1/2] ALSA: hda - Add a new match function for only undef configurations

by Hui Wang

With the existing pintbl, we already have many entries in it. it is better to figure out a new match to reduce the size of the pintbl. For example, there are over 10 entries in the pintbl for: 0x10ec0255, 0x1028, "Dell", ALC255_FIXUP_DELL1_MIC_NO_PRESENCE If we define a new tbl like below, and with the new adding match function, we can remove those over 10 entries: SND_HDA_PIN_QUIRK(0x10ec0255, 0x1028, "Dell", ALC255_FIXUP_DELL1_MIC_NO_PRESENCE, {0x19, 0x40000000}, {0x1a, 0x40000000},), Here we put 0x19 and 0x1a in the tbl just because these two pins are undefined on Dell laptops with the codec alc255, and these two pins will be overwritten by ALC255_FIXUP_DELL1_MIC_NO_PRESENCE. In summary: the new match will check vendor id and codec id first, then check the pin_cfg defined in the tbl, only all pin_cfgs in the tbl are undef and the corresponding pin_cfgs on the laptop are undef too, this match returns true. This new match function has lower priority than existing match functions, so the existing tbls still work as before after applying this patch. My plan is to change the existing tbl to undef tbl for MIC_NO_PRESENCE fixups gradually.

[PATCH] Revert "KVM: x86/mmu: Zap only the relevant pages when removing a memslot"

by Paolo Bonzini

This reverts commit 4e103134b862314dc2f2f18f2fb0ab972adc3f5f. Alex Williamson reported regressions with device assignment with this patch. Even though the bug is probably elsewhere and still latent, this is needed to fix the regression.

[PATCH 1/6] powerpc: Allow flush_icache_range to work across ranges >4GB

by Alastair D'Silva

From: Alastair D'Silva <alastair(a)d-silva.org> When calling flush_icache_range with a size >4GB, we were masking off the upper 32 bits, so we would incorrectly flush a range smaller than intended. This patch replaces the 32 bit shifts with 64 bit ones, so that the full size is accounted for.

[PATCH v5 02/18] xfs: compat_ioctl: add missing conversions

by Arnd Bergmann

FS_IOC_GETFSLABEL/FS_IOC_SETFSLABEL were added in linux-4.18 in xfs, but not in the compat_ioctl case, so add them here. FITRIM was added earlier and also lacks a line the same function, but this is ok because there is an entry in fs/compat_ioctl.c for it. Adding all three here to keep the native and compat ioctl handlers in sync.

FAILED: patch "[PATCH] x86/purgatory: Do not use __builtin_memcpy and" failed to apply to 4.19-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.19-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 4ce97317f41d38584fb93578e922fcd19e535f5b Mon Sep 17 00:00:00 2001 From: Nick Desaulniers <ndesaulniers(a)google.com> Date: Wed, 7 Aug 2019 15:15:32 -0700 Subject: [PATCH] x86/purgatory: Do not use __builtin_memcpy and __builtin_memset Implementing memcpy and memset in terms of __builtin_memcpy and __builtin_memset is problematic. GCC at -O2 will replace calls to the builtins with calls to memcpy and memset (but will generate an inline implementation at -Os). Clang will replace the builtins with these calls regardless of optimization level. $ llvm-objdump -dr arch/x86/purgatory/string.o | tail 0000000000000339 memcpy: 339: 48 b8 00 00 00 00 00 00 00 00 movabsq $0, %rax 000000000000033b: R_X86_64_64 memcpy 343: ff e0 jmpq *%rax 0000000000000345 memset: 345: 48 b8 00 00 00 00 00 00 00 00 movabsq $0, %rax 0000000000000347: R_X86_64_64 memset 34f: ff e0 Such code results in infinite recursion at runtime. This is observed when doing kexec. Instead, reuse an implementation from arch/x86/boot/compressed/string.c. This requires to implement a stub function for warn(). Also, Clang may lower memcmp's that compare against 0 to bcmp's, so add a small definition, too.

[ Upstream commit df612421fe2566654047769c6852ffae1a31df16 ] Commit 63d7ef36103d ("mwifiex: Don't abort on small, spec-compliant vendor IEs") adjusted the ieee_types_vendor_header struct, which inadvertently messed up the offsets used in mwifiex_is_wpa_oui_present(). Add that offset back in, mirroring mwifiex_is_rsn_oui_present(). As it stands, commit 63d7ef36103d breaks compatibility with WPA (not WPA2) 802.11n networks, since we hit the "info: Disable 11n if AES is not supported by AP" case in mwifiex_is_network_compatible().

[PATCH AUTOSEL 4.19 01/42] netfilter: nfnetlink: avoid deadlock due to synchronous request_module

by Sasha Levin

From: Florian Westphal <fw(a)strlen.de> [ Upstream commit 1b0890cd60829bd51455dc5ad689ed58c4408227 ] Thomas and Juliana report a deadlock when running: (rmmod nf_conntrack_netlink/xfrm_user) conntrack -e NEW -E & modprobe -v xfrm_user They provided following analysis: conntrack -e NEW -E netlink_bind() netlink_lock_table() -> increases "nl_table_users" nfnetlink_bind() # does not unlock the table as it's locked by netlink_bind() __request_module() call_usermodehelper_exec() This triggers "modprobe nf_conntrack_netlink" from kernel, netlink_bind() won't return until modprobe process is done. "modprobe xfrm_user": xfrm_user_init() register_pernet_subsys() -> grab pernet_ops_rwsem .. netlink_table_grab() calls schedule() as "nl_table_users" is non-zero so modprobe is blocked because netlink_bind() increased nl_table_users while also holding pernet_ops_rwsem. "modprobe nf_conntrack_netlink" runs and inits nf_conntrack_netlink: ctnetlink_init() register_pernet_subsys() -> blocks on "pernet_ops_rwsem" thanks to xfrm_user module both modprobe processes wait on one another -- neither can make progress. Switch netlink_bind() to "nowait" modprobe -- this releases the netlink table lock, which then allows both modprobe instances to complete.

[PATCH] clk: socfpga: stratix10: fix rate caclulationg for cnt_clks

by Dinh Nguyen

Checking bypass_reg is incorrect for calculating the cnt_clk rates. Instead we should be checking that there is a proper hardware register that holds the clock divider.

There is a small snag with that though: kvm_vgic_vcpu_pending_irq(), which is indirectly called from kvm_vcpu_check_block(), needs to evaluate the guest's view of ICC_PMR_EL1. At the point were we call kvm_vcpu_check_block(), the vcpu is still loaded, and whatever changes to PMR is not visible in memory until we do a vcpu_put(). Things go really south if the guest does the following: mov x0, #0 // or any small value masking interrupts msr ICC_PMR_EL1, x0 [vcpu preempted, then rescheduled, VMCR sampled] mov x0, #ff // allow all interrupts msr ICC_PMR_EL1, x0 wfi // traps to EL2, so samping of VMCR [interrupt arrives just after WFI] Here, the hypervisor's view of PMR is zero, while the guest has enabled its interrupts. kvm_vgic_vcpu_pending_irq() will then say that no interrupts are pending (despite an interrupt being received) and we'll block for no reason. If the guest doesn't have a periodic interrupt firing once it has blocked, it will stay there forever. To avoid this unfortuante situation, let's resync VMCR from kvm_arch_vcpu_blocking(), ensuring that a following kvm_vcpu_check_block() will observe the latest value of PMR.

FAILED: patch "[PATCH] KVM: arm/arm64: Sync ICH_VMCR_EL2 back when about to block" failed to apply to 4.14-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 4.14-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From 5eeaf10eec394b28fad2c58f1f5c3a5da0e87d1c Mon Sep 17 00:00:00 2001 From: Marc Zyngier <maz(a)kernel.org> Date: Fri, 2 Aug 2019 10:28:32 +0100 Subject: [PATCH] KVM: arm/arm64: Sync ICH_VMCR_EL2 back when about to block Since commit commit 328e56647944 ("KVM: arm/arm64: vgic: Defer touching GICH_VMCR to vcpu_load/put"), we leave ICH_VMCR_EL2 (or its GICv2 equivalent) loaded as long as we can, only syncing it back when we're scheduled out. There is a small snag with that though: kvm_vgic_vcpu_pending_irq(), which is indirectly called from kvm_vcpu_check_block(), needs to evaluate the guest's view of ICC_PMR_EL1. At the point were we call kvm_vcpu_check_block(), the vcpu is still loaded, and whatever changes to PMR is not visible in memory until we do a vcpu_put(). Things go really south if the guest does the following: mov x0, #0 // or any small value masking interrupts msr ICC_PMR_EL1, x0 [vcpu preempted, then rescheduled, VMCR sampled] mov x0, #ff // allow all interrupts msr ICC_PMR_EL1, x0 wfi // traps to EL2, so samping of VMCR [interrupt arrives just after WFI] Here, the hypervisor's view of PMR is zero, while the guest has enabled its interrupts. kvm_vgic_vcpu_pending_irq() will then say that no interrupts are pending (despite an interrupt being received) and we'll block for no reason. If the guest doesn't have a periodic interrupt firing once it has blocked, it will stay there forever. To avoid this unfortuante situation, let's resync VMCR from kvm_arch_vcpu_blocking(), ensuring that a following kvm_vcpu_check_block() will observe the latest value of PMR. This has been found by booting an arm64 Linux guest with the pseudo NMI feature, and thus using interrupt priorities to mask interrupts instead of the usual PSTATE masking.

[PATCH] KVM/nSVM: properly map nested VMCB

by Paolo Bonzini

[PATCH v3] Revert "i2c: imx: improve the error handling in i2c_imx_dma_request()"

As a part of i2c_add_numbered_adapter() new I2C slave devices are added from DT which results in a call to driver_deferred_probe_trigger() 3. i2c_imx_probe() continues and calls i2c_imx_dma_request() which due to lack of proper DMA driver returns -EPROBE_DEFER 4. i2c_imx_probe() fails, removes I2C adapter and returns -EPROBE_DEFER, which places it into deferred probe list 5. Deferred probe work triggered in #2 above kicks in and calls i2c_imx_probe() again thus bringing us to step #1" So revert commit e1ab9a468e3b ("i2c: imx: improve the error handling in i2c_imx_dma_request()") and restore the old behaviour, in order to avoid regressions on existing setups.

[PATCH] phy: renesas: rcar-gen3-usb2: Fix sysfs interface of "role"

by Yoshihiro Shimoda

Since the role_store() uses strncmp(), it's possible to refer out-of-memory if the sysfs data size is smaller than strlen("host"). This patch fixes it by using sysfs_streq() instead of strncmp(). Reported-by: Pavel Machek <pavel(a)denx.de> Fixes: 9bb86777fb71 ("phy: rcar-gen3-usb2: add sysfs for usb role swap") Cc: <stable(a)vger.kernel.org> # v4.10+ Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh(a)renesas.com> --- Just a record. The role_store() doesn't need to check the count because the sysfs_streq() checks the first argument is NULL or not. On "if (sysfs_streq(buf, "host"))" Example 1: echo ho > role --> In this case, the count is 3 and the buf has "ho" + NULL. So, the third character differs between NULL and 's'. Example 2: echo host-is-not-used > role --> In this case, the count is 17 and the buf has "host-is-not-used" + NULL. So, the fifth character differs between '-' and NULL. drivers/phy/renesas/phy-rcar-gen3-usb2.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/phy/renesas/phy-rcar-gen3-usb2.c b/drivers/phy/renesas/phy-rcar-gen3-usb2.c index 1322185..cc18970 100644 --- a/drivers/phy/renesas/phy-rcar-gen3-usb2.c +++ b/drivers/phy/renesas/phy-rcar-gen3-usb2.c @@ -20,6 +20,7 @@ #include <linux/platform_device.h> #include <linux/pm_runtime.h> #include <linux/regulator/consumer.h> +#include <linux/string.h> #include <linux/usb/of.h> #include <linux/workqueue.h> @@ -317,9 +318,9 @@ static ssize_t role_store(struct device *dev, struct device_attribute *attr, if (!ch->is_otg_channel || !rcar_gen3_is_any_rphy_initialized(ch)) return -EIO; - if (!strncmp(buf, "host", strlen("host"))) + if (sysfs_streq(buf, "host")) new_mode = PHY_MODE_USB_HOST; - else if (!strncmp(buf, "peripheral", strlen("peripheral"))) + else if (sysfs_streq(buf, "peripheral")) new_mode = PHY_MODE_USB_DEVICE; else return -EINVAL; -- 2.7.4

[PATCH 1/2] ALSA: hda - Let all conexant codec enter D3 when rebooting

by Hui Wang

We have 3 new lenovo laptops which have conexant codec 0x14f11f86, these 3 laptops also have the noise issue when rebooting, after letting the codec enter D3 before rebooting or poweroff, the noise disappers. Instead of adding a new ID again in the reboot_notify(), let us make this function apply to all conexant codec. In theory make codec enter D3 before rebooting or poweroff is harmless, and I tested this change on a couple of other Lenovo laptops which have different conexant codecs, there is no side effect so far.

[PATCH AUTOSEL 5.2 01/76] powerpc: fix off by one in max_zone_pfn initialization for ZONE_DMA

by Sasha Levin

From: Andrea Arcangeli <aarcange(a)redhat.com> [ Upstream commit 03800e0526ee25ed7c843ca1e57b69ac2a5af642 ] 25078dc1f74be16b858e914f52cc8f4d03c2271a first introduced an off by one error in the ZONE_DMA initialization of PPC_BOOK3E_64=y and since 9739ab7eda459f0669ec9807e0d9be5020bab88c the off by one applies to PPC32=y too.

[patch 17/18] mm, vmscan: do not special-case slab reclaim when watermarks are boosted

by akpm＠linux-foundation.org

From: Mel Gorman <mgorman(a)techsingularity.net> Subject: mm, vmscan: do not special-case slab reclaim when watermarks are boosted Dave Chinner reported a problem pointing a finger at commit 1c30844d2dfe ("mm: reclaim small amounts of memory when an external fragmentation event occurs"). The report is extensive (see https://lore.kernel.org/linux-mm/20190807091858.2857-1-david@fromorbit.com/) and it's worth recording the most relevant parts (colorful language and typos included). When running a simple, steady state 4kB file creation test to simulate extracting tarballs larger than memory full of small files into the filesystem, I noticed that once memory fills up the cache balance goes to hell. The workload is creating one dirty cached inode for every dirty page, both of which should require a single IO each to clean and reclaim, and creation of inodes is throttled by the rate at which dirty writeback runs at (via balance dirty pages). Hence the ingest rate of new cached inodes and page cache pages is identical and steady. As a result, memory reclaim should quickly find a steady balance between page cache and inode caches. The moment memory fills, the page cache is reclaimed at a much faster rate than the inode cache, and evidence suggests that the inode cache shrinker is not being called when large batches of pages are being reclaimed. In roughly the same time period that it takes to fill memory with 50% pages and 50% slab caches, memory reclaim reduces the page cache down to just dirty pages and slab caches fill the entirety of memory. The LRU is largely full of dirty pages, and we're getting spikes of random writeback from memory reclaim so it's all going to shit. Behaviour never recovers, the page cache remains pinned at just dirty pages, and nothing I could tune would make any difference. vfs_cache_pressure makes no difference - I would set it so high it should trim the entire inode caches in a single pass, yet it didn't do anything. It was clear from tracing and live telemetry that the shrinkers were pretty much not running except when there was absolutely no memory free at all, and then they did the minimum necessary to free memory to make progress. So I went looking at the code, trying to find places where pages got reclaimed and the shrinkers weren't called. There's only one - kswapd doing boosted reclaim as per commit 1c30844d2dfe ("mm: reclaim small amounts of memory when an external fragmentation event occurs"). The watermark boosting introduced by the commit is triggered in response to an allocation "fragmentation event". The boosting was not intended to target THP specifically and triggers even if THP is disabled. However, with Dave's perfectly reasonable workload, fragmentation events can be very common given the ratio of slab to page cache allocations so boosting remains active for long periods of time. As high-order allocations might use compaction and compaction cannot move slab pages the decision was made in the commit to special-case kswapd when watermarks are boosted -- kswapd avoids reclaiming slab as reclaiming slab does not directly help compaction. As Dave notes, this decision means that slab can be artificially protected for long periods of time and messes up the balance with slab and page caches. Removing the special casing can still indirectly help avoid fragmentation by avoiding fragmentation-causing events due to slab allocation as pages from a slab pageblock will have some slab objects freed. Furthermore, with the special casing, reclaim behaviour is unpredictable as kswapd sometimes examines slab and sometimes does not in a manner that is tricky to tune or analyse. This patch removes the special casing. The downside is that this is not a universal performance win. Some benchmarks that depend on the residency of data when rereading metadata may see a regression when slab reclaim is restored to its original behaviour. Similarly, some benchmarks that only read-once or write-once may perform better when page reclaim is too aggressive. The primary upside is that slab shrinker is less surprising (arguably more sane but that's a matter of opinion), behaves consistently regardless of the fragmentation state of the system and properly obeys VM sysctls. A fsmark benchmark configuration was constructed similar to what Dave reported and is codified by the mmtest configuration config-io-fsmark-small-file-stream. It was evaluated on a 1-socket machine to avoid dealing with NUMA-related issues and the timing of reclaim. The storage was an SSD Samsung Evo and a fresh trimmed XFS filesystem was used for the test data. This is not an exact replication of Dave's setup. The configuration scales its parameters depending on the memory size of the SUT to behave similarly across machines. The parameters mean the first sample reported by fs_mark is using 50% of RAM which will barely be throttled and look like a big outlier. Dave used fake NUMA to have multiple kswapd instances which I didn't replicate. Finally, the number of iterations differ from Dave's test as the target disk was not large enough. While not identical, it should be representative. fsmark 5.3.0-rc3 5.3.0-rc3 vanilla shrinker-v1r1 Min 1-files/sec 4444.80 ( 0.00%) 4765.60 ( 7.22%) 1st-qrtle 1-files/sec 5005.10 ( 0.00%) 5091.70 ( 1.73%) 2nd-qrtle 1-files/sec 4917.80 ( 0.00%) 4855.60 ( -1.26%) 3rd-qrtle 1-files/sec 4667.40 ( 0.00%) 4831.20 ( 3.51%) Max-1 1-files/sec 11421.50 ( 0.00%) 9999.30 ( -12.45%) Max-5 1-files/sec 11421.50 ( 0.00%) 9999.30 ( -12.45%) Max-10 1-files/sec 11421.50 ( 0.00%) 9999.30 ( -12.45%) Max-90 1-files/sec 4649.60 ( 0.00%) 4780.70 ( 2.82%) Max-95 1-files/sec 4491.00 ( 0.00%) 4768.20 ( 6.17%) Max-99 1-files/sec 4491.00 ( 0.00%) 4768.20 ( 6.17%) Max 1-files/sec 11421.50 ( 0.00%) 9999.30 ( -12.45%) Hmean 1-files/sec 5004.75 ( 0.00%) 5075.96 ( 1.42%) Stddev 1-files/sec 1778.70 ( 0.00%) 1369.66 ( 23.00%) CoeffVar 1-files/sec 33.70 ( 0.00%) 26.05 ( 22.71%) BHmean-99 1-files/sec 5053.72 ( 0.00%) 5101.52 ( 0.95%) BHmean-95 1-files/sec 5053.72 ( 0.00%) 5101.52 ( 0.95%) BHmean-90 1-files/sec 5107.05 ( 0.00%) 5131.41 ( 0.48%) BHmean-75 1-files/sec 5208.45 ( 0.00%) 5206.68 ( -0.03%) BHmean-50 1-files/sec 5405.53 ( 0.00%) 5381.62 ( -0.44%) BHmean-25 1-files/sec 6179.75 ( 0.00%) 6095.14 ( -1.37%) 5.3.0-rc3 5.3.0-rc3 vanillashrinker-v1r1 Duration User 501.82 497.29 Duration System 4401.44 4424.08 Duration Elapsed 8124.76 8358.05 This is showing a slight skew for the max result representing a large outlier for the 1st, 2nd and 3rd quartile are similar indicating that the bulk of the results show little difference. Note that an earlier version of the fsmark configuration showed a regression but that included more samples taken while memory was still filling. Note that the elapsed time is higher. Part of this is that the configuration included time to delete all the test files when the test completes -- the test automation handles the possibility of testing fsmark with multiple thread counts. Without the patch, many of these objects would be memory resident which is part of what the patch is addressing. There are other important observations that justify the patch. 1. With the vanilla kernel, the number of dirty pages in the system is very low for much of the test. With this patch, dirty pages is generally kept at 10% which matches vm.dirty_background_ratio which is normal expected historical behaviour. 2. With the vanilla kernel, the ratio of Slab/Pagecache is close to 0.95 for much of the test i.e. Slab is being left alone and dominating memory consumption. With the patch applied, the ratio varies between 0.35 and 0.45 with the bulk of the measured ratios roughly half way between those values. This is a different balance to what Dave reported but it was at least consistent. 3. Slabs are scanned throughout the entire test with the patch applied. The vanille kernel has periods with no scan activity and then relatively massive spikes. 4. Without the patch, kswapd scan rates are very variable. With the patch, the scan rates remain quite stead. 4. Overall vmstats are closer to normal expectations 5.3.0-rc3 5.3.0-rc3 vanilla shrinker-v1r1 Ops Direct pages scanned 99388.00 328410.00 Ops Kswapd pages scanned 45382917.00 33451026.00 Ops Kswapd pages reclaimed 30869570.00 25239655.00 Ops Direct pages reclaimed 74131.00 5830.00 Ops Kswapd efficiency % 68.02 75.45 Ops Kswapd velocity 5585.75 4002.25 Ops Page reclaim immediate 1179721.00 430927.00 Ops Slabs scanned 62367361.00 73581394.00 Ops Direct inode steals 2103.00 1002.00 Ops Kswapd inode steals 570180.00 5183206.00 o Vanilla kernel is hitting direct reclaim more frequently, not very much in absolute terms but the fact the patch reduces it is interesting o "Page reclaim immediate" in the vanilla kernel indicates dirty pages are being encountered at the tail of the LRU. This is generally bad and means in this case that the LRU is not long enough for dirty pages to be cleaned by the background flush in time. This is much reduced by the patch. o With the patch, kswapd is reclaiming 10 times more slab pages than with the vanilla kernel. This is indicative of the watermark boosting over-protecting slab A more complete set of tests were run that were part of the basis for introducing boosting and while there are some differences, they are well within tolerances. Bottom line, the special casing kswapd to avoid slab behaviour is unpredictable and can lead to abnormal results for normal workloads. This patch restores the expected behaviour that slab and page cache is balanced consistently for a workload with a steady allocation ratio of slab/pagecache pages. It also means that if there are workloads that favour the preservation of slab over pagecache that it can be tuned via vm.vfs_cache_pressure where as the vanilla kernel effectively ignores the parameter when boosting is active.

[patch 13/18] seq_file: fix problem when seeking mid-record

by akpm＠linux-foundation.org

From: NeilBrown <neilb(a)suse.com> Subject: seq_file: fix problem when seeking mid-record If you use lseek or similar (e.g. pread) to access a location in a seq_file file that is within a record, rather than at a record boundary, then the first read will return the remainder of the record, and the second read will return the whole of that same record (instead of the next record). When seeking to a record boundary, the next record is correctly returned. This bug was introduced by a recent patch (identified below). Before that patch, seq_read() would increment m->index when the last of the buffer was returned (m->count == 0). After that patch, we rely on ->next to increment m->index after filling the buffer - but there was one place where that didn't happen.

[patch 11/18] mm/usercopy: use memory range to be accessed for wraparound check

by akpm＠linux-foundation.org

From: "Isaac J. Manjarres" <isaacm(a)codeaurora.org> Subject: mm/usercopy: use memory range to be accessed for wraparound check Currently, when checking to see if accessing n bytes starting at address "ptr" will cause a wraparound in the memory addresses, the check in check_bogus_address() adds an extra byte, which is incorrect, as the range of addresses that will be accessed is [ptr, ptr + (n - 1)]. This can lead to incorrectly detecting a wraparound in the memory address, when trying to read 4 KB from memory that is mapped to the the last possible page in the virtual address space, when in fact, accessing that range of memory would not cause a wraparound to occur. Use the memory range that will actually be accessed when considering if accessing a certain amount of bytes will cause the memory address to wrap around.

When calling mbind(), it would scan the vma to queue the pages for migration to the new node. It would split any huge page since 4.9 doesn't support THP migration, however, the packet tx ring compound pages are not THP and even not movable. So, the above bug is triggered. However, the later kernel is not hit by this issue due to d44d363f65780f2ac2 ("mm: don't assume anonymous pages have SwapBacked flag"), which just removes the PageSwapBacked check for a different reason. But, there is a deeper issue. According to the semantic of mbind(), it should return -EIO if MPOL_MF_MOVE or MPOL_MF_MOVE_ALL was specified and MPOL_MF_STRICT was also specified, but the kernel was unable to move all existing pages in the range. The tx ring of the packet socket is definitely not movable, however, mbind() returns success for this case. Although the most socket file associates with non-movable pages, but XDP may have movable pages from gup. So, it sounds not fine to just check the underlying file type of vma in vma_migratable(). Change migrate_page_add() to check if the page is movable or not, if it is unmovable, just return -EIO. But do not abort pte walk immediately, since there may be pages off LRU temporarily. We should migrate other pages if MPOL_MF_MOVE* is specified. Set has_unmovable flag if some paged could not be not moved, then return -EIO for mbind() eventually. With this change the above test would return -EIO as expected.

[patch 04/18] mm: mempolicy: make the behavior consistent when MPOL_MF_MOVE* and MPOL_MF_STRICT were specified

by akpm＠linux-foundation.org

From: Yang Shi <yang.shi(a)linux.alibaba.com> Subject: mm: mempolicy: make the behavior consistent when MPOL_MF_MOVE* and MPOL_MF_STRICT were specified When both MPOL_MF_MOVE* and MPOL_MF_STRICT was specified, mbind() should try best to migrate misplaced pages, if some of the pages could not be migrated, then return -EIO. There are three different sub-cases: 1. vma is not migratable 2. vma is migratable, but there are unmovable pages 3. vma is migratable, pages are movable, but migrate_pages() fails If #1 happens, kernel would just abort immediately, then return -EIO, after a7f40cfe3b7ada ("mm: mempolicy: make mbind() return -EIO when MPOL_MF_STRICT is specified"). If #3 happens, kernel would set policy and migrate pages with best-effort, but won't rollback the migrated pages and reset the policy back. Before that commit, they behaves in the same way. It'd better to keep their behavior consistent. But, rolling back the migrated pages and resetting the policy back sounds not feasible, so just make #1 behave as same as #3. Userspace will know that not everything was successfully migrated (via -EIO), and can take whatever steps it deems necessary - attempt rollback, determine which exact page(s) are violating the policy, etc. Make queue_pages_range() return 1 to indicate there are unmovable pages or vma is not migratable.

[patch 03/18] mm/hmm: fix bad subpage pointer in try_to_unmap_one

by akpm＠linux-foundation.org

From: Ralph Campbell <rcampbell(a)nvidia.com> Subject: mm/hmm: fix bad subpage pointer in try_to_unmap_one When migrating an anonymous private page to a ZONE_DEVICE private page, the source page->mapping and page->index fields are copied to the destination ZONE_DEVICE struct page and the page_mapcount() is increased. This is so rmap_walk() can be used to unmap and migrate the page back to system memory. However, try_to_unmap_one() computes the subpage pointer from a swap pte which computes an invalid page pointer and a kernel panic results such as: BUG: unable to handle page fault for address: ffffea1fffffffc8 Currently, only single pages can be migrated to device private memory so no subpage computation is needed and it can be set to "page".

[patch 02/18] mm/hmm: fix ZONE_DEVICE anon page mapping reuse

by akpm＠linux-foundation.org

From: Ralph Campbell <rcampbell(a)nvidia.com> Subject: mm/hmm: fix ZONE_DEVICE anon page mapping reuse When a ZONE_DEVICE private page is freed, the page->mapping field can be set. If this page is reused as an anonymous page, the previous value can prevent the page from being inserted into the CPU's anon rmap table. For example, when migrating a pte_none() page to device memory: migrate_vma(ops, vma, start, end, src, dst, private) migrate_vma_collect() src[] = MIGRATE_PFN_MIGRATE migrate_vma_prepare() /* no page to lock or isolate so OK */ migrate_vma_unmap() /* no page to unmap so OK */ ops->alloc_and_copy() /* driver allocates ZONE_DEVICE page for dst[] */ migrate_vma_pages() migrate_vma_insert_page() page_add_new_anon_rmap() __page_set_anon_rmap() /* This check sees the page's stale mapping field */ if (PageAnon(page)) return /* page->mapping is not updated */ The result is that the migration appears to succeed but a subsequent CPU fault will be unable to migrate the page back to system memory or worse. Clear the page->mapping field when freeing the ZONE_DEVICE page so stale pointer data doesn't affect future page use.

+ mm-page_alloc-move_freepages-should-not-examine-struct-page-of-reserved-memory.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm, page_alloc: move_freepages should not examine struct page of reserved memory has been added to the -mm tree. Its filename is mm-page_alloc-move_freepages-should-not-examine-struct-page-of-reserved-memory.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-page_alloc-move_freepages-shoul… and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-page_alloc-move_freepages-shoul… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: David Rientjes <rientjes(a)google.com> Subject: mm, page_alloc: move_freepages should not examine struct page of reserved memory After commit 907ec5fca3dc ("mm: zero remaining unavailable struct pages"), struct page of reserved memory is zeroed. This causes page->flags to be 0 and fixes issues related to reading /proc/kpageflags, for example, of reserved memory. The VM_BUG_ON() in move_freepages_block(), however, assumes that page_zone() is meaningful even for reserved memory. That assumption is no longer true after the aforementioned commit. There's no reason why move_freepages_block() should be testing the legitimacy of page_zone() for reserved memory; its scope is limited only to pages on the zone's freelist. Note that pfn_valid() can be true for reserved memory: there is a backing struct page. The check for page_to_nid(page) is also buggy but reserved memory normally only appears on node 0 so the zeroing doesn't affect this. Move the debug checks to after verifying PageBuddy is true. This isolates the scope of the checks to only be for buddy pages which are on the zone's freelist which move_freepages_block() is operating on. In this case, an incorrect node or zone is a bug worthy of being warned about (and the examination of struct page is acceptable bcause this memory is not reserved). Why does move_freepages_block() gets called on reserved memory? It's simply math after finding a valid free page from the per-zone free area to use as fallback. We find the beginning and end of the pageblock of the valid page and that can bring us into memory that was reserved per the e820. pfn_valid() is still true (it's backed by a struct page), but since it's zero'd we shouldn't make any inferences here about comparing its node or zone. The current node check just happens to succeed most of the time by luck because reserved memory typically appears on node 0. The fix here is to validate that we actually have buddy pages before testing if there's any type of zone or node strangeness going on.

Prefer that pattern to wiping out all of the important KBUILD_CFLAGS then manually having to re-add them.

Given the conflicts, I can provide back-ports once upstream upon request. It should be noted that the backports should be mechanical and trivial (skip non-existent filesystems like orangfs, drop separate inode argument that did not exist in earlier kernels). I will submit the next spin (missed a few filesystems, build errors) with references to the requested stable trees again, so noise will continue. Sincerely -- Mark Salyzyn

by Benjamin Tissoires

The G700 suffers from the same issue than the G502: when plugging it in, the driver tries to contact it but it fails. This timeout is problematic as it introduce a delay in the boot, and having only the mouse event node means that the hardware macros keys can not be relayed to the userspace.

[4.14 PATCH] lkdtm: support llvm-objcopy

by Nick Desaulniers

commit e9e08a07385e08f1a7f85c5d1e345c21c9564963 upstream. With CONFIG_LKDTM=y and make OBJCOPY=llvm-objcopy, llvm-objcopy errors: llvm-objcopy: error: --set-section-flags=.text conflicts with --rename-section=.text=.rodata Rather than support setting flags then renaming sections vs renaming then setting flags, it's simpler to just change both at the same time via --rename-section. Adding the load flag is required for GNU objcopy to mark .rodata Type as PROGBITS after the rename. This can be verified with: $ readelf -S drivers/misc/lkdtm/rodata_objcopy.o ... Section Headers: [Nr] Name Type Address Offset Size EntSize Flags Link Info Align ... [ 1] .rodata PROGBITS 0000000000000000 00000040 0000000000000004 0000000000000000 A 0 0 4 ... Which shows that .text is now renamed .rodata, the alloc flag A is set, the type is PROGBITS, and the section is not flagged as writeable W.

[PATCH v2] drm/nouveau: Only recalculate PBN/VCPI on mode/connector changes

by Lyude Paul

I -thought- I had fixed this entirely, but it looks like that I didn't test this thoroughly enough as we apparently still make one big mistake with nv50_msto_atomic_check() - we don't handle the following scenario: * CRTC #1 has n VCPI allocated to it, is attached to connector DP-4 which is attached to encoder #1. enabled=y active=n * CRTC #1 is changed from DP-4 to DP-5, causing: * DP-4 crtc=#1→NULL (VCPI n→0) * DP-5 crtc=NULL→#1 * CRTC #1 steals encoder #1 back from DP-4 and gives it to DP-5 * CRTC #1 maintains the same mode as before, just with a different connector * mode_changed=n connectors_changed=y (we _SHOULD_ do VCPI 0→n here, but don't) Once the above scenario is repeated once, we'll attempt freeing VCPI from the connector that we didn't allocate due to the connectors changing, but the mode staying the same. Sigh. Since nv50_msto_atomic_check() has broken a few times now, let's rethink things a bit to be more careful: limit both VCPI/PBN allocations to mode_changed || connectors_changed, since neither VCPI or PBN should ever need to change outside of routing and mode changes.

[PATCH] xtensa: add missing isync to the cpu_reset TLB code

patch "USB: core: Fix races in character device registration and" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: core: Fix races in character device registration and to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 303911cfc5b95d33687d9046133ff184cf5043ff Mon Sep 17 00:00:00 2001 From: Alan Stern <stern(a)rowland.harvard.edu> Date: Mon, 12 Aug 2019 16:11:07 -0400 Subject: USB: core: Fix races in character device registration and deregistraion The syzbot fuzzer has found two (!) races in the USB character device registration and deregistration routines. This patch fixes the races. The first race results from the fact that usb_deregister_dev() sets usb_minors[intf->minor] to NULL before calling device_destroy() on the class device. This leaves a window during which another thread can allocate the same minor number but will encounter a duplicate name error when it tries to register its own class device. A typical error message in the system log would look like: sysfs: cannot create duplicate filename '/class/usbmisc/ldusb0' The patch fixes this race by destroying the class device first. The second race is in usb_register_dev(). When that routine runs, it first allocates a minor number, then drops minor_rwsem, and then creates the class device. If the device creation fails, the minor number is deallocated and the whole routine returns an error. But during the time while minor_rwsem was dropped, there is a window in which the minor number is allocated and so another thread can successfully open the device file. Typically this results in use-after-free errors or invalid accesses when the other thread closes its open file reference, because the kernel then tries to release resources that were already deallocated when usb_register_dev() failed. The patch fixes this race by keeping minor_rwsem locked throughout the entire routine.

[PATCH] dma-mapping: Use unsigned types for size checks

by Isaac J. Manjarres

Both the size parameter in the dma_alloc_from_[dev/global]_coherent() functions and the size field in the dma_coherent_mem structure are represented by a signed quantity, which makes it so that any comparisons between these two quantities is a signed comparison. When a reserved memory region is larger than or equal to 2GB in size, this will cause the most significant bit to be set to 1, thus, treating the size as a negative number in signed comparisons. This can result in allocation failures when an amount of memory that is strictly less than 2 GB is requested from this region. The allocation fails because the signed comparison to prevent from allocating more memory than what is in the region in __dma_alloc_from_coherent() evaluates to true since the size of the region is treated as a negative number, but the size of the request is treated as a positive number. Thus, change the type of the size parameter in the allocation functions to an unsigned type, and change the type of the size field in the dma_coherent_mem structure to an unsigned type as well, as it does not make sense for sizes to be represented by signed quantities.

[PATCH] mmc: core: Prevent processing SDIO IRQs when the card is suspended

by Ulf Hansson

Processing of SDIO IRQs must obviously be prevented while the card is system suspended, otherwise we may end up trying to communicate with an uninitialized SDIO card. Reports throughout the years shows that this is not only a theoretical problem, but a real issue. So, let's finally fix this problem, by keeping track of the state for the card and bail out before processing the SDIO IRQ, in case the card is suspended. Cc: stable(a)vger.kernel.org Reported-by: Douglas Anderson <dianders(a)chromium.org> Signed-off-by: Ulf Hansson <ulf.hansson(a)linaro.org> --- This has only been compile tested so far, any help for real test on HW is greatly appreciated. Note that, this is only the initial part of what is needed to make power management of SDIO card more robust, but let's start somewhere and continue to improve things. The next step I am looking at right now, is to make sure the SDIO IRQ is turned off during system suspend, unless it's supported as a system wakeup (and enabled to be used). --- drivers/mmc/core/sdio.c | 7 +++++++ drivers/mmc/core/sdio_irq.c | 4 ++++ 2 files changed, 11 insertions(+) diff --git a/drivers/mmc/core/sdio.c b/drivers/mmc/core/sdio.c index d1aa1c7577bb..9951295d3220 100644 --- a/drivers/mmc/core/sdio.c +++ b/drivers/mmc/core/sdio.c @@ -937,6 +937,10 @@ static int mmc_sdio_pre_suspend(struct mmc_host *host) */ static int mmc_sdio_suspend(struct mmc_host *host) { + /* Prevent processing of SDIO IRQs in suspended state. */ + mmc_card_set_suspended(host->card); + cancel_delayed_work_sync(&host->sdio_irq_work); + mmc_claim_host(host); if (mmc_card_keep_power(host) && mmc_card_wake_sdio_irq(host)) @@ -985,6 +989,9 @@ static int mmc_sdio_resume(struct mmc_host *host) err = sdio_enable_4bit_bus(host->card); } + /* Allow SDIO IRQs to be processed again. */ + mmc_card_clr_suspended(host->card); + if (!err && host->sdio_irqs) { if (!(host->caps2 & MMC_CAP2_SDIO_IRQ_NOTHREAD)) wake_up_process(host->sdio_irq_thread); diff --git a/drivers/mmc/core/sdio_irq.c b/drivers/mmc/core/sdio_irq.c index 931e6226c0b3..9f54a259a1b3 100644 --- a/drivers/mmc/core/sdio_irq.c +++ b/drivers/mmc/core/sdio_irq.c @@ -34,6 +34,10 @@ static int process_sdio_pending_irqs(struct mmc_host *host) unsigned char pending; struct sdio_func *func; + /* Don't process SDIO IRQs if the card is suspended. */ + if (mmc_card_suspended(card)) + return 0; + /* * Optimization, if there is only 1 function interrupt registered * and we know an IRQ was signaled then call irq handler directly. -- 2.17.1

[PATCH] dma-buf/sw_sync: Synchronize signal vs syncpt free

by Chris Wilson

During release of the syncpt, we remove it from the list of syncpt and the tree, but only if it is not already been removed. However, during signaling, we first remove the syncpt from the list. So, if we concurrently free and signal the syncpt, the free may decide that it is not part of the tree and immediately free itself -- meanwhile the signaler goes onto to use the now freed datastructure. In particular, we get struct by commit 0e2f733addbf ("dma-buf: make dma_fence structure a bit smaller v2") as the cb_list is immediately clobbered by the kfree_rcu.

Reports from the CKI Project are back!

by Major Hayden

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello there, The CKI is pleased to announce that we are enabling automated reports again for the stable mailing list! We now upload more logs to help with troubleshooting failures. Build logs from a failed kernel compile are uploaded to our artifacts server instead of being sent with the report email as an attachment. The logs from our testing phase (when we boot the kernel on a host and run tests) are also available on the artifacts server. This should make it easier to understand why a particular test failed. Take a look at a recent stable kernel test[0] to see the new test logs. Our testing is focused heavily on the latest kernel updates, so we will keep tracking the latest stable kernel version. Testing against 4.19 has been challenging for us since it's not our main focus, so we dropped testing for 4.19 from our system. Our team is eager to get your feedback! If you find something that you like, or if you find something that could be improved, please let us know anytime at cki-project(a)redhat.com.

From: Balbir Singh <bsingharora(a)gmail.com> The current code would fail on huge pages addresses, since the shift would be incorrect. Use the correct page shift value returned by __find_linux_pte() to get the correct physical address. The code is more generic and can handle both regular and compound pages.

[PATCH 1/2] powerpc: Allow flush_icache_range to work across ranges >4GB

by Alastair D'Silva

From: Alastair D'Silva <alastair(a)d-silva.org> When calling flush_icache_range with a size >4GB, we were masking off the upper 32 bits, so we would incorrectly flush a range smaller than intended. This patch replaces the 32 bit shifts with 64 bit ones, so that the full size is accounted for. Heads-up for backporters: the old version of flush_dcache_range is subject to a similar bug (this has since been replaced with a C implementation).

Software reset for all means this reset affects the entire Host controller except for the card detection circuit. In sdhci_runtime_resume_host() we always do a software "reset for all", which causes the Spreadtrum variant controller to work abnormally after resuming. To fix the problem, let's do a software reset for the data and the command part, rather than "for all". However, as sdhci_runtime_resume() is a common sdhci function and we don't want to change the behaviour for other variants, let's introduce a new in-parameter for it. This enables the caller to decide if a "reset for all" shall be done or not.

[PATCH 1/2] mfd: rave-sp: Bump command timeout to 5 seconds

by Fabio Estevam

From: Andrey Smirnov <andrew.smirnov(a)gmail.com> Command to erase application firmware on RAVE SP takes longer than one second (it takes ~3s). Bump command timeout duration to 5 seconds in order to avoid bogus timeouts.
