[PATCH 5.15] ice: safer stats processing

by Przemek Kitszel

From: Jesse Brandeburg <jesse.brandeburg(a)intel.com> [ Upstream commit 1a0f25a52e08b1f67510cabbb44888d2b3c46359 ] Fix an issue of stats growing indefinitely, minor conflict resolved: struct ice_tx_ring replaced by struct ice_ring, as the split is not yet present on 5.15 line. -Przemek Original commit message: The driver was zeroing live stats that could be fetched by ndo_get_stats64 at any time. This could result in inconsistent statistics, and the telltale sign was when reading stats frequently from /proc/net/dev, the stats would go backwards. Fix by collecting stats into a local, and delaying when we write to the structure so it's not incremental.

[PATCH 5.15.y v3] xen: replace xen_remap() with memremap()

by Teddy Astie

From: Juergen Gross <jgross(a)suse.com> [ upstream commit 41925b105e345ebc84cedb64f59d20cb14a62613 ] xen_remap() is used to establish mappings for frames not under direct control of the kernel: for Xenstore and console ring pages, and for grant pages of non-PV guests. Today xen_remap() is defined to use ioremap() on x86 (doing uncached mappings), and ioremap_cache() on Arm (doing cached mappings). Uncached mappings for those use cases are bad for performance, so they should be avoided if possible. As all use cases of xen_remap() don't require uncached mappings (the mapped area is always physical RAM), a mapping using the standard WB cache mode is fine. As sparse is flagging some of the xen_remap() use cases to be not appropriate for iomem(), as the result is not annotated with the __iomem modifier, eliminate xen_remap() completely and replace all use cases with memremap() specifying the MEMREMAP_WB caching mode. xen_unmap() can be replaced with memunmap().

[PATCH] drm/framebuffer: Acquire internal references on GEM handles

by Thomas Zimmermann

Acquire GEM handles in drm_framebuffer_init() and release them in the corresponding drm_framebuffer_cleanup(). Ties the handle's lifetime to the framebuffer. Not all GEM buffer objects have GEM handles. If not set, no refcounting takes place. This is the case for some fbdev emulation. This is not a problem as these GEM objects do not use dma-bufs and drivers will not release them while fbdev emulation is running. As all drivers use drm_framebuffer_init(), they will now all hold dma-buf references as fixed in commit 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers"). In the GEM framebuffer helpers, restore the original ref counting on buffer objects. As the helpers for handle refcounting are now no longer called from outside the DRM core, unexport the symbols. Gma500 (unnecessarily) clears the framebuffer's GEM-object pointer before calling drm_framebuffer_cleanup(). Remove these lines to make it consistent with the rest of the drivers. It's one of the fbdev emulations with no GEM handle on their buffers. The change to gma500 is therefore rather cosmetic. Tested on i915, amdgpu (by Bert) and gma500. Also tested on i915 plus udl for the original problem with dma-buf sharing.

[PATCH] comedi: Fail COMEDI_INSNLIST ioctl if n_insns is too large

by Ian Abbott

The handling of the `COMEDI_INSNLIST` ioctl allocates a kernel buffer to hold the array of `struct comedi_insn`, getting the length from the `n_insns` member of the `struct comedi_insnlist` supplied by the user. The allocation will fail with a WARNING and a stack dump if it is too large. Avoid that by failing with an `-EINVAL` error if the supplied `n_insns` value is unreasonable. Define the limit on the `n_insns` value in the `MAX_INSNS` macro. Set this to the same value as `MAX_SAMPLES` (65536), which is the maximum allowed sum of the values of the member `n` in the array of `struct comedi_insn`, and sensible comedi instructions will have an `n` of at least 1.

[PATCH 5.10] bpf: Reject variable offset alu on PTR_TO_FLOW_KEYS

by Anastasia Belova

From: Hao Sun <sunhao.th(a)gmail.com> [ Upstream commit 22c7fa171a02d310e3a3f6ed46a698ca8a0060ed ] For PTR_TO_FLOW_KEYS, check_flow_keys_access() only uses fixed off for validation.

[PATCH v1 mm-hotfixes] mm/zsmalloc: do not pass __GFP_MOVABLE if CONFIG_COMPACTION=n

by Harry Yoo

Commit 48b4800a1c6a ("zsmalloc: page migration support") added support for migrating zsmalloc pages using the movable_operations migration framework. However, the commit did not take into account that zsmalloc supports migration only when CONFIG_COMPACTION is enabled. Tracing shows that zsmalloc was still passing the __GFP_MOVABLE flag even when compaction is not supported. This can result in unmovable pages being allocated from movable page blocks (even without stealing page blocks), ZONE_MOVABLE and CMA area. Clear the __GFP_MOVABLE flag when !IS_ENABLED(CONFIG_COMPACTION).

[PATCH 5.15.y] xfs: fix super block buf log item UAF during force shutdown

by Pranav Tyagi

From: Guo Xuenan <guoxuenan(a)huawei.com> [ Upstream commit 575689fc0ffa6c4bb4e72fd18e31a6525a6124e0 ] xfs log io error will trigger xlog shut down, and end_io worker call xlog_state_shutdown_callbacks to unpin and release the buf log item.

[REGRESSION] - Multiple userspace implementations of battery estimate broken after "ACPI: battery: negate current when discharging"

by Matthew Schwartz

Hello, I installed kernel 6.15.4 to find that my battery estimate on my handheld gaming device was completely inaccurate, instead giving negative values and an unknown estimated battery life in multiple places. After bisecting, I landed on "ACPI: battery: negate current when discharging” as the bad commit. This commit breaks not one but several userspace implementations of battery monitoring: Steam and MangoHud. Perhaps it breaks more, but those are the two I have noticed so far. Thanks, Matthew Schwartz

[PATCH v2] drm/gem: Acquire references on GEM handles for framebuffers

by Thomas Zimmermann

A GEM handle can be released while the GEM buffer object is attached to a DRM framebuffer. This leads to the release of the dma-buf backing the buffer object, if any. [1] Trying to use the framebuffer in further mode-setting operations leads to a segmentation fault. Most easily happens with driver that use shadow planes for vmap-ing the dma-buf during a page flip. An example is shown below.

[PATCH] gpiolib: fix efficiency regression when using gpio_chip_get_multiple()

by Hugo Villeneuve

From: Hugo Villeneuve <hvilleneuve(a)dimonoff.com> commit 74abd086d2ee ("gpiolib: sanitize the return value of gpio_chip::get_multiple()") altered the value returned by gc->get_multiple() in case it is positive (> 0), but failed to return for other cases (<= 0). This may result in the "if (gc->get)" block being executed and thus negates the performance gain that is normally obtained by using gc->get_multiple(). Fix by returning the result of gc->get_multiple() if it is <= 0. Also move the "ret" variable to the scope where it is used, which as an added bonus fixes an indentation error introduced by the aforementioned commit.

[REGRESSION] Packet loss after hot-plugging ethernet cable on HP Zbook (Arrow Lake)

by En-Wei WU

Hi, I'm seeing a regression on an HP ZBook using the e1000e driver (chipset PCI ID: [8086:57a0]) -- the system can't get an IP address after hot-plugging an Ethernet cable. In this case, the Ethernet cable was unplugged at boot. The network interface eno1 was present but stuck in the DHCP process. Using tcpdump, only TX packets were visible and never got any RX -- indicating a possible packet loss or link-layer issue. This is on the vanilla Linux 6.16-rc4 (commit 62f224733431dbd564c4fe800d4b67a0cf92ed10). Bisect says it's this commit: commit efaaf344bc2917cbfa5997633bc18a05d3aed27f Author: Vitaly Lifshits <vitaly.lifshits(a)intel.com> Date: Thu Mar 13 16:05:56 2025 +0200 e1000e: change k1 configuration on MTP and later platforms Starting from Meteor Lake, the Kumeran interface between the integrated MAC and the I219 PHY works at a different frequency. This causes sporadic MDI errors when accessing the PHY, and in rare circumstances could lead to packet corruption. To overcome this, introduce minor changes to the Kumeran idle state (K1) parameters during device initialization. Hardware reset reverts this configuration, therefore it needs to be applied in a few places.

[PATCH v3] fscrypt: Don't use problematic non-inline crypto engines

by Eric Biggers

Make fscrypt no longer use Crypto API drivers for non-inline crypto engines, even when the Crypto API prioritizes them over CPU-based code (which unfortunately it often does). These drivers tend to be really problematic, especially for fscrypt's workload. This commit has no effect on inline crypto engines, which are different and do work well. Specifically, exclude drivers that have CRYPTO_ALG_KERN_DRIVER_ONLY or CRYPTO_ALG_ALLOCATES_MEMORY set. (Later, CRYPTO_ALG_ASYNC should be excluded too. That's omitted for now to keep this commit backportable, since until recently some CPU-based code had CRYPTO_ALG_ASYNC set.) There are two major issues with these drivers: bugs and performance. First, these drivers tend to be buggy. They're fundamentally much more error-prone and harder to test than the CPU-based code. They often don't get tested before kernel releases, and even if they do, the crypto self-tests don't properly test these drivers. Released drivers have en/decrypted or hashed data incorrectly. These bugs cause issues for fscrypt users who often didn't even want to use these drivers, e.g.: - https://github.com/google/fscryptctl/issues/32 - https://github.com/google/fscryptctl/issues/9 - https://lore.kernel.org/r/PH0PR02MB731916ECDB6C613665863B6CFFAA2@PH0PR02MB7… These drivers have also similarly caused issues for dm-crypt users, including data corruption and deadlocks. Since Linux v5.10, dm-crypt has disabled most of them by excluding CRYPTO_ALG_ALLOCATES_MEMORY. Second, these drivers tend to be *much* slower than the CPU-based code. This may seem counterintuitive, but benchmarks clearly show it. There's a *lot* of overhead associated with going to a hardware driver, off the CPU, and back again. To prove this, I gathered as many systems with this type of crypto engine as I could, and I measured synchronous encryption of 4096-byte messages (which matches fscrypt's workload): Intel Emerald Rapids server: AES-256-XTS: xts-aes-vaes-avx512 16171 MB/s [CPU-based, Vector AES] qat_aes_xts 289 MB/s [Offload, Intel QuickAssist] Qualcomm SM8650 HDK: AES-256-XTS: xts-aes-ce 4301 MB/s [CPU-based, ARMv8 Crypto Extensions] xts-aes-qce 73 MB/s [Offload, Qualcomm Crypto Engine] i.MX 8M Nano LPDDR4 EVK: AES-256-XTS: xts-aes-ce 647 MB/s [CPU-based, ARMv8 Crypto Extensions] xts(ecb-aes-caam) 20 MB/s [Offload, CAAM] AES-128-CBC-ESSIV: essiv(cbc-aes-caam,sha256-lib) 23 MB/s [Offload, CAAM] STM32MP157F-DK2: AES-256-XTS: xts-aes-neonbs 13.2 MB/s [CPU-based, ARM NEON] xts(stm32-ecb-aes) 3.1 MB/s [Offload, STM32 crypto engine] AES-128-CBC-ESSIV: essiv(cbc-aes-neonbs,sha256-lib) 14.7 MB/s [CPU-based, ARM NEON] essiv(stm32-cbc-aes,sha256-lib) 3.2 MB/s [Offload, STM32 crypto engine] Adiantum: adiantum(xchacha12-arm,aes-arm,nhpoly1305-neon) 52.8 MB/s [CPU-based, ARM scalar + NEON] So, there was no case in which the crypto engine was even *close* to being faster. On the first three, which have AES instructions in the CPU, the CPU was 30 to 55 times faster (!). Even on STM32MP157F-DK2 which has a Cortex-A7 CPU that doesn't have AES instructions, AES was over 4 times faster on the CPU. And Adiantum encryption, which is what actually should be used on CPUs like that, was over 17 times faster. Other justifications that have been given for these non-inline crypto engines (almost always coming from the hardware vendors, not actual users) don't seem very plausible either: - The crypto engine throughput could be improved by processing multiple requests concurrently. Currently irrelevant to fscrypt, since it doesn't do that. This would also be complex, and unhelpful in many cases. 2 of the 4 engines I tested even had only one queue. - Some of the engines, e.g. STM32, support hardware keys. Also currently irrelevant to fscrypt, since it doesn't support these. Interestingly, the STM32 driver itself doesn't support this either. - Free up CPU for other tasks and/or reduce energy usage. Not very plausible considering the "short" message length, driver overhead, and scheduling overhead. There's just very little time for the CPU to do something else like run another task or enter low-power state, before the message finishes and it's time to process the next one. - Some of these engines resist power analysis and electromagnetic attacks, while the CPU-based crypto generally does not. In theory, this sounds great. In practice, if this benefit requires the use of an off-CPU offload that massively regresses performance and has a low-quality, buggy driver, the price for this hardening (which is not relevant to most fscrypt users, and tends to be incomplete) is just too high. Inline crypto engines are much more promising here, as are on-CPU solutions like RISC-V High Assurance Cryptography.

[PATCH] efi/tpm: Fix the issue where the CC platforms event log header can't be correctly identified

by yangge1116＠126.com

From: Ge Yang <yangge1116(a)126.com> Since commit d228814b1913 ("efi/libstub: Add get_event_log() support for CC platforms") reuses TPM2 support code for the CC platforms, when launching a TDX virtual machine with coco measurement enabled, the following error log is generated: [Firmware Bug]: Failed to parse event in TPM Final Events Log Call Trace: efi_config_parse_tables() efi_tpm_eventlog_init() tpm2_calc_event_log_size() __calc_tpm2_event_size() The pcr_idx value in the Intel TDX log header is 1, causing the function __calc_tpm2_event_size() to fail to recognize the log header, ultimately leading to the "Failed to parse event in TPM Final Events Log" error. According to UEFI Spec 2.10 Section 38.4.1: For Tdx, TPM PCR 0 maps to MRTD, so the log header uses TPM PCR 1. To successfully parse the TDX event log header, the check for a pcr_idx value of 0 has been removed here, and it appears that this will not affect other functionalities.

[PATCH 1/1] iommu/vt-d: Optimize iotlb_sync_map for non-caching/non-RWBF modes

by Lu Baolu

The iotlb_sync_map iommu ops allows drivers to perform necessary cache flushes when new mappings are established. For the Intel iommu driver, this callback specifically serves two purposes: - To flush caches when a second-stage page table is attached to a device whose iommu is operating in caching mode (CAP_REG.CM==1). - To explicitly flush internal write buffers to ensure updates to memory- resident remapping structures are visible to hardware (CAP_REG.RWBF==1). However, in scenarios where neither caching mode nor the RWBF flag is active, the cache_tag_flush_range_np() helper, which is called in the iotlb_sync_map path, effectively becomes a no-op. Despite being a no-op, cache_tag_flush_range_np() involves iterating through all cache tags of the iommu's attached to the domain, protected by a spinlock. This unnecessary execution path introduces overhead, leading to a measurable I/O performance regression. On systems with NVMes under the same bridge, performance was observed to drop from approximately ~6150 MiB/s down to ~4985 MiB/s. Introduce a flag in the dmar_domain structure. This flag will only be set when iotlb_sync_map is required (i.e., when CM or RWBF is set). The cache_tag_flush_range_np() is called only for domains where this flag is set.
