[PATCH v3] ALSA: usb-audio: disable 96khz support for HUAWEI USB-C HEADSET

by Macpaul Lin

The HUAWEI USB-C headset (VID:0x12d1, PID:0x3a07) reported it supports 96khz. However there will be some random issue under 96khz. Not sure if there is any alternate setting could be applied. Hence 48khz is suggested to be applied at this moment.

+ mm-zsmallocc-drop-zsmalloc_pgtable_mapping.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/zsmalloc.c: drop ZSMALLOC_PGTABLE_MAPPING has been added to the -mm tree. Its filename is mm-zsmallocc-drop-zsmalloc_pgtable_mapping.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/mm-zsmallocc-drop-zsmalloc_pgtabl… and later at https://ozlabs.org/~akpm/mmotm/broken-out/mm-zsmallocc-drop-zsmalloc_pgtabl… 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: Minchan Kim <minchan(a)kernel.org> Subject: mm/zsmalloc.c: drop ZSMALLOC_PGTABLE_MAPPING While I was doing zram testing, I found sometimes decompression failed since the compression buffer was corrupted. With investigation, I found below commit calls cond_resched unconditionally so it could make a problem in atomic context if the task is reschedule.

Even though this option showed some amount improvement(e.g., 30%) in some arm32 platforms, it has been headache to maintain since it have abused APIs[1](e.g., unmap_kernel_range in atomic context). Since we are approaching to deprecate 32bit machines and already made the config option available for only builtin build since v5.8, lastly it has been not default option in zsmalloc, it's time to drop the option for better maintainance.

[PATCH v2 1/8] powernv/memtrace: don't leak kernel memory to user space

by David Hildenbrand

The parsing of the reboot= cmdline has two major errors: - a missing bound check can crash the system on reboot - parsing of the cpu number only works if specified last Fix both. This patch (of 2): This reverts commit 616feab753972b97. kstrtoint() and simple_strtoul() have a subtle difference which makes them non interchangeable: if a non digit character is found amid the parsing, the former will return an error, while the latter will just stop parsing, e.g. simple_strtoul("123xyx") = 123. The kernel cmdline reboot= argument allows to specify the CPU used for rebooting, with the syntax `s####` among the other flags, e.g. "reboot=warm,s31,force", so if this flag is not the last given, it's silently ignored as well as the subsequent ones.

[PATCH stable-5.9 1/2] coresight: etm: perf: Sink selection using sysfs is deprecated

by Linu Cherian

commit bb1860efc817c18fce4112f25f51043e44346d1b upstream. When commit 6d578258b955 ("coresight: Make sysfs functional on topologies with per core sink") was merged to stable, this patch was a pre-requisite and got missed out leading to build breakages. When using the perf interface, sink selection using sysfs is deprecated.

[PATCH] x86/speculation: Allow IBPB to be conditionally enabled on CPUs with always-on STIBP

by Anand K Mistry

commit 1978b3a53a74e3230cd46932b149c6e62e832e9a upstream. On AMD CPUs which have the feature X86_FEATURE_AMD_STIBP_ALWAYS_ON, STIBP is set to on and spectre_v2_user_stibp == SPECTRE_V2_USER_STRICT_PREFERRED At the same time, IBPB can be set to conditional. However, this leads to the case where it's impossible to turn on IBPB for a process because in the PR_SPEC_DISABLE case in ib_prctl_set() the spectre_v2_user_stibp == SPECTRE_V2_USER_STRICT_PREFERRED condition leads to a return before the task flag is set. Similarly, ib_prctl_get() will return PR_SPEC_DISABLE even though IBPB is set to conditional. More generally, the following cases are possible: 1. STIBP = conditional && IBPB = on for spectre_v2_user=seccomp,ibpb 2. STIBP = on && IBPB = conditional for AMD CPUs with X86_FEATURE_AMD_STIBP_ALWAYS_ON The first case functions correctly today, but only because spectre_v2_user_ibpb isn't updated to reflect the IBPB mode. At a high level, this change does one thing. If either STIBP or IBPB is set to conditional, allow the prctl to change the task flag. Also, reflect that capability when querying the state. This isn't perfect since it doesn't take into account if only STIBP or IBPB is unconditionally on. But it allows the conditional feature to work as expected, without affecting the unconditional one.

This is acceptable when memory backing is enabled as the device queue is in that case marked as blocking, but this triggers a scheduling while in atomic context with memory backing disabled. Fix this by relying solely on the device zone spinlock for zone information protection without temporarily releasing this lock around null_process_cmd() execution in null_zone_write(). This is OK to do since when memory backing is disabled, command processing does not block and the memory backing lock nullb->lock is unused. This solution avoids the overhead of having to mark a zoned null_blk device queue as blocking when memory backing is unused. This patch also adds comments to the zone locking code to explain the unusual locking scheme.

[PATCH stable-5.4] drm/i915: Correctly set SFC capability for video engines

by Daniele Ceraolo Spurio

From: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota(a)intel.com> Commit 5ce6861d36ed5207aff9e5eead4c7cc38a986586 upstream. This backport targets stable version 5.4, since the original patch fails to apply there, due to a variable having moved from one struct to another. The only change required for the patch to apply to 5.4 is to use the correct structure: - (engine->gt->info.vdbox_sfc_access & ++ (RUNTIME_INFO(i915)->vdbox_sfc_access & Original commit message below. SFC capability of video engines is not set correctly because i915 is testing for incorrect bits.

patch "iio: accel: kxcjk1013: Add support for KIOX010A ACPI DSM for setting" added to staging-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: accel: kxcjk1013: Add support for KIOX010A ACPI DSM for setting to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-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 e5b1032a656e9aa4c7a4df77cb9156a2a651a5f9 Mon Sep 17 00:00:00 2001 From: Hans de Goede <hdegoede(a)redhat.com> Date: Tue, 10 Nov 2020 14:38:35 +0100 Subject: iio: accel: kxcjk1013: Add support for KIOX010A ACPI DSM for setting tablet-mode Some 360 degree hinges (yoga) style 2-in-1 devices use 2 KXCJ91008-s to allow the OS to determine the angle between the display and the base of the device, so that the OS can determine if the 2-in-1 is in laptop or in tablet-mode. On Windows both accelerometers are read by a special HingeAngleService process; and this process calls a DSM (Device Specific Method) on the ACPI KIOX010A device node for the sensor in the display, to let the embedded-controller (EC) know about the mode so that it can disable the kbd and touchpad to avoid spurious input while folded into tablet-mode. This notifying of the EC is problematic because sometimes the EC comes up thinking that device is in tablet-mode and the kbd and touchpad do not work. This happens for example on Irbis NB111 devices after a suspend / resume cycle (after a complete battery drain / hard reset without having booted Windows at least once). Other 2-in-1s which are likely affected too are e.g. the Teclast F5 and F6 series. The kxcjk-1013 driver may seem like a strange place to deal with this, but since it is *the* driver for the ACPI KIOX010A device, it is also the driver which has access to the ACPI handle needed by the DSM. Add support for calling the DSM and on probe unconditionally tell the EC that the device is laptop mode, fixing the kbd and touchpad sometimes not working.

patch "iio: adc: stm32-adc: fix a regression when using dma and irq" added to staging-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: adc: stm32-adc: fix a regression when using dma and irq to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-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 695e2f5c289bb7f8b85351dcfa35fa236e0200a4 Mon Sep 17 00:00:00 2001 From: Olivier Moysan <olivier.moysan(a)st.com> Date: Wed, 21 Oct 2020 10:53:13 +0200 Subject: iio: adc: stm32-adc: fix a regression when using dma and irq Since overrun interrupt support has been added, there's a regression when two ADCs are used at the same time, with: - an ADC configured to use IRQs. EOCIE bit is set. The handler is normally called in this case. - an ADC configured to use DMA. EOCIE bit isn't set. EOC triggers the DMA request. It's then automatically cleared by DMA read. But the handler gets called due to status bit is temporarily set (IRQ triggered by the other ADC). This is a regression as similar issue had been fixed earlier by commit dcb10920179a ("iio: adc: stm32-adc: fix a race when using several adcs with dma and irq"). Issue is that stm32_adc_eoc_enabled() returns non-zero value (always) since OVR bit has been added and enabled for both DMA and IRQ case. Remove OVR mask in IER register, and rely only on CSR status for overrun. To avoid subsequent calls to interrupt routine on overrun, CSR OVR bit has to be cleared. CSR OVR bit cannot be cleared directly by software. To do this ADC must be stopped first, and OVR bit in ADC ISR has to be cleared. Also add a check in ADC IRQ handler to report spurious IRQs.

[PATCH][v2] x86/microcode/intel: check cpu stepping and processor flag before saving microcode

by Chen Yu

Currently scan_microcode() leverages microcode_matches() to check if the microcode matches the CPU by comparing the family and model. However before saving the microcode in scan_microcode(), the processor stepping and flag of the microcode signature should also be considered in order to avoid incompatible update and caused the failure of microcode update. For example on one platform the microcode failed to be updated to the latest revison on APs during resume from S3 due to incompatible cpu stepping and signature->pf. This is because the scan_microcode() has saved an incompatible copy of intel_ucode_patch in save_microcode_in_initrd_intel() after bootup. And this intel_ucode_patch is used by APs during early resume from S3 which results in unchecked MSR access error during resume from S3: [ 95.519390] unchecked MSR access error: RDMSR from 0x123 at rIP: 0xffffffffb7676208 (native_read_msr+0x8/0x40) [ 95.519391] Call Trace: [ 95.519395] update_srbds_msr+0x38/0x80 [ 95.519396] identify_secondary_cpu+0x7a/0x90 [ 95.519397] smp_store_cpu_info+0x4e/0x60 [ 95.519398] start_secondary+0x49/0x150 [ 95.519399] secondary_startup_64_no_verify+0xa6/0xab The system keeps running on old microcode during resume: [ 210.366757] microcode: load_ucode_intel_ap: CPU1, enter, intel_ucode_patch: 0xffff9bf2816e0000 [ 210.366757] microcode: load_ucode_intel_ap: CPU1, p: 0xffff9bf2816e0000, rev: 0xd6 [ 210.366759] microcode: apply_microcode_early: rev: 0x84 [ 210.367826] microcode: apply_microcode_early: rev after upgrade: 0x84 until mc_cpu_starting() is invoked on each AP during resume and the correct microcode is updated via apply_microcode_intel(). To fix this issue, the scan_microcode() uses find_matching_signature() instead of microcode_matches() to compare the (family, model, stepping, processor flag), and only save the microcode that matches. As there is no other place invoking microcode_matches(), remove it accordingly.

[PATCH] ubifs: wbuf: Don't leak kernel memory to flash

by Richard Weinberger

Write buffers use a kmalloc()'ed buffer, they can leak up to seven bytes of kernel memory to flash if writes are not aligned. So use ubifs_pad() to fill these gaps with padding bytes. This was never a problem while scanning because the scanner logic manually aligns node lengths and skips over these gaps.

[PATCH] unlz4: Handle 0-size chunks, discard trailing padding/garbage

by siarhei.liakh＠concurrent-rt.com

From: Siarhei Liakh <siarhei.liakh(a)concurrent-rt.com> TL;DR: There are two places in unlz4() function where reads beyond the end of a buffer might happen under certain conditions which had been observed in real life on stock Ubuntu 20.04 x86_64 with several vanilla mainline kernels, including 5.10. As a result of this issue, the kernel fails to decompress LZ4-compressed initramfs with following message showing up in the logs: initramfs unpacking failed: Decoding failed Note that in most cases the affected system is still able to proceed with the boot process to completion. LONG STORY: Background. Not so long ago we've noticed that some of our Ubuntu 20.04 x86_64 test systems often fail to boot newly generated initramfs image. After extensive investigation we determined that a failure required the following combination for our 5.4.66-rt38 kernel with some additional custom patches: Real x86_64 hardware or QEMU UEFI boot Ubunutu 20.04 (or 20.04.1) x86_64 CONFIG_BLK_DEV_RAM=y in .config COMPRESS=lz4 in initramfs.conf Freshly compiled and installed kernel Freshly generated and installed initramfs image In our testing, such a combination would often produce a non-bootable system. It is important to note that [un]bootability of the system was later tracked down to particular instances of initramfs images, and would follow them if they were to be switched around/transferred to other systems. What is even more important is that consecutive re-generations of initramfs images from the same source and binary materials would yield about 75% of "bad" images. Further, once the image is identified as "bad",it always stays "bad"; once one is "good" it always stays "good". Reverting CONFIG_BLK_DEV_RAM to "m" (default in Ubuntu), or changing COMPRESS to "gzip" yields a 100% bootable system. Decompressing "bad" initramfs image with "unmkinitramfs" yields *exactly* the same set of binaries, as verified by matching MD5 sums to those from "good" image. Speculation. Based on general observations, it appears that Ubuntu's userland toolchain cannot consistently generate exactly the same compressed initramfs image, likely due to some variations in timestamps between the runs. This causes variations in compressed lz4 data stream. Further, either initramfs tools or lz4 libraries appear to pad compressed lz4 output to closest 4-byte boundary. lz4 v1.9.2 that ships with Ubuntu 20.04 appears to be able to handle such padding just fine, while lz4 (supposedly v1.8.3) within Linux kernel cannot. Several reports of somewhat similar behavior had been recently circulation through different bug tracking systems and discussion forums [1-4]. I also suspect only that systems which can mount permanent root directly (or with help of modules contained in first, supposedly uncompressed, part of initramfs, or the ones with statically linked modules) can actually complete the boot when LZ4 decompression fails. This would certainly explain why most of Ubuntu systems still manage to boot even after failing to decompress the image. The facts. Regardless of whether Ubuntu 20.04 toolchain produces a valid lz4-compressed initramfs image or not, current version of unlz4() function in kernel has two code paths which had been observed attempting to read beyond the buffer end when presented with one of the "padded"/"bad" initramfs images generated by stock Ubuntu 20.04 toolchain. Some configurations of some 5.4 kernels are known to fail to boot in such cases. This behavior also becomes evident on vanilla 5.10.0-rc3 and 5.10.0-rc4 kernels with addition of two logging statements for corresponding edge cases, even though it does not prevent system from booting in most generic configurations. Further investigation is likely warranted to confirm whether userland toolchain contains any bugs and/or whether any of these cases constitute violation of LZ4 and/or initramfs specification.

+ page_frag-recover-from-memory-pressure.patch added to -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm, page_frag: recover from memory pressure has been added to the -mm tree. Its filename is page_frag-recover-from-memory-pressure.patch This patch should soon appear at https://ozlabs.org/~akpm/mmots/broken-out/page_frag-recover-from-memory-pre… and later at https://ozlabs.org/~akpm/mmotm/broken-out/page_frag-recover-from-memory-pre… 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: Dongli Zhang <dongli.zhang(a)oracle.com> Subject: mm, page_frag: recover from memory pressure The ethernet driver may allocate skb (and skb->data) via napi_alloc_skb(). This ends up to page_frag_alloc() to allocate skb->data from page_frag_cache->va. During the memory pressure, page_frag_cache->va may be allocated as pfmemalloc page. As a result, the skb->pfmemalloc is always true as skb->data is from page_frag_cache->va. The skb will be dropped if the sock (receiver) does not have SOCK_MEMALLOC. This is expected behaviour under memory pressure. However, once kernel is not under memory pressure any longer (suppose large amount of memory pages are just reclaimed), the page_frag_alloc() may still re-use the prior pfmemalloc page_frag_cache->va to allocate skb->data. As a result, the skb->pfmemalloc is always true unless page_frag_cache->va is re-allocated, even if the kernel is not under memory pressure any longer. Here is how kernel runs into issue. 1. The kernel is under memory pressure and allocation of PAGE_FRAG_CACHE_MAX_ORDER in __page_frag_cache_refill() will fail. Instead, the pfmemalloc page is allocated for page_frag_cache->va. 2. All skb->data from page_frag_cache->va (pfmemalloc) will have skb->pfmemalloc=true. The skb will always be dropped by sock without SOCK_MEMALLOC. This is an expected behaviour. 3. Suppose a large amount of pages are reclaimed and kernel is not under memory pressure any longer. We expect skb->pfmemalloc drop will not happen. 4. Unfortunately, page_frag_alloc() does not proactively re-allocate page_frag_alloc->va and will always re-use the prior pfmemalloc page.

[PATCH] drm/i915: Handle max_bpc==16

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> EDID can declare the maximum supported bpc up to 16, and apparently there are displays that do so. Currently we assume 12 bpc is tha max. Fix the assumption and toss in a MISSING_CASE() for any other value we don't expect to see. This fixes modesets with a display with EDID max bpc > 12. Previously any modeset would just silently fail on platforms that didn't otherwise limit this via the max_bpc property. In particular we don't add the max_bpc property to HDMI ports on gmch platforms, and thus we would see the raw max_bpc coming from the EDID. I suppose we could already adjust this to also allow 16bpc, but seeing as no current platform supports that there is little point.

[merged] ocfs2-initialize-ip_next_orphan.patch removed from -mm tree

Looking at the code, 2067 /* Skip inodes which are already added to recover list, since dio may 2068 * happen concurrently with unlink/rename */ 2069 if (OCFS2_I(iter)->ip_next_orphan) { 2070 iput(iter); 2071 return 0; 2072 } 2073 The logic thinks the inode is already in recover list on seeing ip_next_orphan is non-NULL, so it skip this inode after dropping a reference which incremented in ocfs2_iget(). While, if the inode is already in recover list, it should have another reference and the iput() at line 2070 should not be the final iput (dropping the last reference). So I don't think the inode is really in the recover list (no vmcore to confirm). Note that ocfs2_queue_orphans(), though not shown up in the call back trace, is holding cluster lock on the orphan directory when looking up for unlinked inodes. The on disk inode eviction could involve a lot of IOs which may need long time to finish. That means this node could hold the cluster lock for very long time, that can lead to the lock requests (from other nodes) to the orhpan directory hang for long time. Looking at more on ip_next_orphan, I found it's not initialized when allocating a new ocfs2_inode_info structure. This causes te reflink operations from some nodes hang for very long time waiting for the cluster lock on the orphan directory. Fix: initialize ip_next_orphan as NULL.

Specifically, the routine unmap_and_move_huge_page() is always passing the TTU_RMAP_LOCKED flag to try_to_unmap() while holding i_mmap_rwsem. This is wrong for anon pages as the anon_vma_lock should be held in this case. Further analysis suggested that i_mmap_rwsem was not required to he held at all when calling try_to_unmap for anon pages as an anon page could never be part of a shared pmd mapping. Discussion also revealed that the hack in hugetlb_page_mapping_lock_write to drop page lock and acquire i_mmap_rwsem is wrong. There is no way to keep mapping valid while dropping page lock. This patch does the following: - Do not take i_mmap_rwsem and set TTU_RMAP_LOCKED for anon pages when calling try_to_unmap. - Remove the hacky code in hugetlb_page_mapping_lock_write. The routine will now simply do a 'trylock' while still holding the page lock. If the trylock fails, it will return NULL. This could impact the callers: - migration calling code will receive -EAGAIN and retry up to the hard coded limit (10). - memory error code will treat the page as BUSY. This will force killing (SIGKILL) instead of SIGBUS any mapping tasks. Do note that this change in behavior only happens when there is a race. None of the standard kernel testing suites actually hit this race, but it is possible.

[merged] revert-kernel-rebootc-convert-simple_strtoul-to-kstrtoint.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: Revert "kernel/reboot.c: convert simple_strtoul to kstrtoint" has been removed from the -mm tree. Its filename was revert-kernel-rebootc-convert-simple_strtoul-to-kstrtoint.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Matteo Croce <mcroce(a)microsoft.com> Subject: Revert "kernel/reboot.c: convert simple_strtoul to kstrtoint" Patch series "fix parsing of reboot= cmdline", v3. The parsing of the reboot= cmdline has two major errors: - a missing bound check can crash the system on reboot - parsing of the cpu number only works if specified last Fix both. This patch (of 2): This reverts commit 616feab753972b97. kstrtoint() and simple_strtoul() have a subtle difference which makes them non interchangeable: if a non digit character is found amid the parsing, the former will return an error, while the latter will just stop parsing, e.g. simple_strtoul("123xyx") = 123. The kernel cmdline reboot= argument allows to specify the CPU used for rebooting, with the syntax `s####` among the other flags, e.g. "reboot=warm,s31,force", so if this flag is not the last given, it's silently ignored as well as the subsequent ones.

[merged] compilerh-fix-barrier_data-on-clang.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: compiler.h: fix barrier_data() on clang has been removed from the -mm tree. Its filename was compilerh-fix-barrier_data-on-clang.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Arvind Sankar <nivedita(a)alum.mit.edu> Subject: compiler.h: fix barrier_data() on clang Commit 815f0ddb346c ("include/linux/compiler*.h: make compiler-*.h mutually exclusive") neglected to copy barrier_data() from compiler-gcc.h into compiler-clang.h. The definition in compiler-gcc.h was really to work around clang's more aggressive optimization, so this broke barrier_data() on clang, and consequently memzero_explicit() as well. For example, this results in at least the memzero_explicit() call in lib/crypto/sha256.c:sha256_transform() being optimized away by clang. Fix this by moving the definition of barrier_data() into compiler.h. Also move the gcc/clang definition of barrier() into compiler.h, __memory_barrier() is icc-specific (and barrier() is already defined using it in compiler-intel.h) and doesn't belong in compiler.h.

Thus checking for the page pointer is required too. The cache flush is done through an inter processor interrupt when a piece of memory is off-lined. That interrupt is triggered when a memory hot-unplug operation is initiated and offline_pages() is calling the slub's MEM_GOING_OFFLINE callback slab_mem_going_offline_callback() which is calling flush_cpu_slab(). If that interrupt is caught between the reading of c->freelist and the reading of c->page, this could lead to such a situation. That situation is expected and the later call to this_cpu_cmpxchg_double() will detect the change to c->freelist and redo the whole operation. In commit 6159d0f5c03e ("mm/slub.c: page is always non-NULL in node_match()") check on the page pointer has been removed assuming that page is always valid when it is called. It happens that this is not true in that particular case, so check for page before calling node_match() here.

[merged] mm-compaction-count-pages-and-stop-correctly-during-page-isolation.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm/compaction: count pages and stop correctly during page isolation has been removed from the -mm tree. Its filename was mm-compaction-count-pages-and-stop-correctly-during-page-isolation.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Zi Yan <ziy(a)nvidia.com> Subject: mm/compaction: count pages and stop correctly during page isolation In isolate_migratepages_block, when cc->alloc_contig is true, we are able to isolate compound pages, nr_migratepages and nr_isolated did not count compound pages correctly, causing us to isolate more pages than we thought. Count compound pages as the number of base pages they contain. Otherwise, we might be trapped in too_many_isolated while loop, since the actual isolated pages can go up to COMPACT_CLUSTER_MAX*512=16384, where COMPACT_CLUSTER_MAX is 32, since we stop isolation after cc->nr_migratepages reaches to COMPACT_CLUSTER_MAX. In addition, after we fix the issue above, cc->nr_migratepages could never be equal to COMPACT_CLUSTER_MAX if compound pages are isolated, thus page isolation could not stop as we intended. Change the isolation stop condition to >=. The issue can be triggered as follows: In a system with 16GB memory and an 8GB CMA region reserved by hugetlb_cma, if we first allocate 10GB THPs and mlock them (so some THPs are allocated in the CMA region and mlocked), reserving 6 1GB hugetlb pages via /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages will get stuck (looping in too_many_isolated function) until we kill either task. With the patch applied, oom will kill the application with 10GB THPs and let hugetlb page reservation finish.

Also, romfs/cramfs don't have their own on-disk timestamp, and squashfs only records mtime instead.

patch "tty: serial: imx: fix potential deadlock" added to tty-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled tty: serial: imx: fix potential deadlock 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-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 33f16855dcb973f745c51882d0e286601ff3be2b Mon Sep 17 00:00:00 2001 From: Sam Nobs <samuel.nobs(a)taitradio.com> Date: Tue, 10 Nov 2020 09:50:06 +1300 Subject: tty: serial: imx: fix potential deadlock MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enabling the lock dependency validator has revealed that the way spinlocks are used in the IMX serial port could result in a deadlock. Specifically, imx_uart_int() acquires a spinlock without disabling the interrupts, meaning that another interrupt could come along and try to acquire the same spinlock, potentially causing the two to wait for each other indefinitely. Use spin_lock_irqsave() instead to disable interrupts upon acquisition of the spinlock.

[PATCH v2 1/9] block: Fix a race in the runtime power management code

by Bart Van Assche

With the current implementation the following race can happen: * blk_pre_runtime_suspend() calls blk_freeze_queue_start() and blk_mq_unfreeze_queue(). * blk_queue_enter() calls blk_queue_pm_only() and that function returns true. * blk_queue_enter() calls blk_pm_request_resume() and that function does not call pm_request_resume() because the queue runtime status is RPM_ACTIVE. * blk_pre_runtime_suspend() changes the queue status into RPM_SUSPENDING. Fix this race by changing the queue runtime status into RPM_SUSPENDING before switching q_usage_counter to atomic mode.

This patch (of 2): This reverts commit 616feab753972b97. kstrtoint() and simple_strtoul() have a subtle difference which makes them non interchangeable: if a non digit character is found amid the parsing, the former will return an error, while the latter will just stop parsing, e.g. simple_strtoul("123xyx") = 123. The kernel cmdline reboot= argument allows to specify the CPU used for rebooting, with the syntax `s####` among the other flags, e.g. "reboot=warm,s31,force", so if this flag is not the last given, it's silently ignored as well as the subsequent ones.

The definition in compiler-gcc.h was really to work around clang's more aggressive optimization, so this broke barrier_data() on clang, and consequently memzero_explicit() as well. For example, this results in at least the memzero_explicit() call in lib/crypto/sha256.c:sha256_transform() being optimized away by clang. Fix this by moving the definition of barrier_data() into compiler.h. Also move the gcc/clang definition of barrier() into compiler.h, __memory_barrier() is icc-specific (and barrier() is already defined using it in compiler-intel.h) and doesn't belong in compiler.h.

[PATCH v3 2/7] crypto: sun4i-ss: checking sg length is not sufficient

The optimized cipher function need length multiple of 4 bytes. But it get sometimes odd length. This is due to SG data could be stored with an offset. So the fix is to check also if the offset is aligned with 4 bytes.
