[PATCH 6.1.y] ipv4: Fix uninit-value access in __ip_make_skb()

by Zhaoyang Li

From: Shigeru Yoshida <syoshida(a)redhat.com> [ Upstream commit fc1092f51567277509563800a3c56732070b6aa4 ] KMSAN reported uninit-value access in __ip_make_skb() [1]. __ip_make_skb() tests HDRINCL to know if the skb has icmphdr. However, HDRINCL can cause a race condition. If calling setsockopt(2) with IP_HDRINCL changes HDRINCL while __ip_make_skb() is running, the function will access icmphdr in the skb even if it is not included. This causes the issue reported by KMSAN. Check FLOWI_FLAG_KNOWN_NH on fl4->flowi4_flags instead of testing HDRINCL on the socket. Also, fl4->fl4_icmp_type and fl4->fl4_icmp_code are not initialized. These are union in struct flowi4 and are implicitly initialized by flowi4_init_output(), but we should not rely on specific union layout. Initialize these explicitly in raw_sendmsg().

[PATCH 6.1] userfaultfd: fix checks for huge PMDs

by Xiangyu Chen

From: Jann Horn <jannh(a)google.com> commit 71c186efc1b2cf1aeabfeff3b9bd5ac4c5ac14d8 upstream. Patch series "userfaultfd: fix races around pmd_trans_huge() check", v2. The pmd_trans_huge() code in mfill_atomic() is wrong in three different ways depending on kernel version: 1. The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit the right two race windows) - I've tested this in a kernel build with some extra mdelay() calls. See the commit message for a description of the race scenario. On older kernels (before 6.5), I think the same bug can even theoretically lead to accessing transhuge page contents as a page table if you hit the right 5 narrow race windows (I haven't tested this case). 2. As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for detecting PMDs that don't point to page tables. On older kernels (before 6.5), you'd just have to win a single fairly wide race to hit this. I've tested this on 6.1 stable by racing migration (with a mdelay() patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86 VM, that causes a kernel oops in ptlock_ptr(). 3. On newer kernels (>=6.5), for shmem mappings, khugepaged is allowed to yank page tables out from under us (though I haven't tested that), so I think the BUG_ON() checks in mfill_atomic() are just wrong. I decided to write two separate fixes for these (one fix for bugs 1+2, one fix for bug 3), so that the first fix can be backported to kernels affected by bugs 1+2. This patch (of 2): This fixes two issues. I discovered that the following race can occur: mfill_atomic other thread ============ ============ <zap PMD> pmdp_get_lockless() [reads none pmd] <bail if trans_huge> <if none:> <pagefault creates transhuge zeropage> __pte_alloc [no-op] <zap PMD> <bail if pmd_trans_huge(*dst_pmd)> BUG_ON(pmd_none(*dst_pmd)) I have experimentally verified this in a kernel with extra mdelay() calls; the BUG_ON(pmd_none(*dst_pmd)) triggers. On kernels newer than commit 0d940a9b270b ("mm/pgtable: allow pte_offset_map[_lock]() to fail"), this can't lead to anything worse than a BUG_ON(), since the page table access helpers are actually designed to deal with page tables concurrently disappearing; but on older kernels (<=6.4), I think we could probably theoretically race past the two BUG_ON() checks and end up treating a hugepage as a page table. The second issue is that, as Qi Zheng pointed out, there are other types of huge PMDs that pmd_trans_huge() can't catch: devmap PMDs and swap PMDs (in particular, migration PMDs). On <=6.4, this is worse than the first issue: If mfill_atomic() runs on a PMD that contains a migration entry (which just requires winning a single, fairly wide race), it will pass the PMD to pte_offset_map_lock(), which assumes that the PMD points to a page table. Breakage follows: First, the kernel tries to take the PTE lock (which will crash or maybe worse if there is no "struct page" for the address bits in the migration entry PMD - I think at least on X86 there usually is no corresponding "struct page" thanks to the PTE inversion mitigation, amd64 looks different). If that didn't crash, the kernel would next try to write a PTE into what it wrongly thinks is a page table. As part of fixing these issues, get rid of the check for pmd_trans_huge() before __pte_alloc() - that's redundant, we're going to have to check for that after the __pte_alloc() anyway. Backport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels.

[PATCH v2 0/5] rtc: Fix problems with missing UIE irqs

by Esben Haabendal

This fixes a couple of different problems, that can cause RTC (alarm) irqs to be missing when generating UIE interrupts. The first commit fixes a long-standing problem, which has been documented in a comment since 2010. This fixes a race that could cause UIE irqs to stop being generated, which was easily reproduced by timing the use of RTC_UIE_ON ioctl with the seconds tick in the RTC. The last commit ensures that RTC (alarm) irqs are enabled whenever RTC_UIE_ON ioctl is used. The driver specific commits avoids kernel warnings about unbalanced enable_irq/disable_irq, which gets triggered on first RTC_UIE_ON with the last commit. Before this series, the same warning should be seen on initial RTC_AIE_ON with those drivers.

[PATCH v2 2/2] usb: dwc3: Force full reset on xhci removal

by Roy Luo

During an xhci host controller reset (via `USBCMD.HCRST`), reading DWC3 registers can return zero instead of their actual values. This applies not only to registers within the xhci memory space but also those in the broader DWC3 IP block. By default, the xhci driver doesn't wait for the reset handshake to complete during teardown. This can cause problems when the DWC3 controller is operating as a dual role device and is switching from host to device mode, the invalid register read caused by ongoing HCRST could lead to gadget mode startup failures and unintended register overwrites. To mitigate this, enable xhci-full-reset-on-remove-quirk to ensure that xhci_reset() completes its full reset handshake during xhci removal.

[PATCH] drm: radeon: ci_dpm: Add error handling for ci_send_msg_to_smc_with_parameter()

by Wentao Liang

The ci_enable_uvd_dpm() calls ci_send_msg_to_smc_with_parameter() but does not check the return value. This could lead to the execution with potentially invalid data. A proper implementation can be found in the ci_fan_ctrl_start_smc_fan_control(). Add a check after calling ci_send_msg_to_smc_with_parameter(), return -EINVAL if the sending fails.

[PATCH] arm64: Check pxd_leaf() instead of !pxd_table() while tearing down page tables

by Dev Jain

Commit 9c006972c3fe removes the pxd_present() checks because the caller checks pxd_present(). But, in case of vmap_try_huge_pud(), the caller only checks pud_present(); pud_free_pmd_page() recurses on each pmd through pmd_free_pte_page(), wherein the pmd may be none. Thus it is possible to hit a warning in the latter, since pmd_none => !pmd_table(). Thus, enforce these checks again through pxd_leaf(). This problem was found by code inspection. The patch is based on 6.15-rc6.

[PATCH v2 0/5] Fix onboard USB hub instability on RK3399 Puma SoM

by Lukasz Czechowski

The RK3399 Puma SoM contains the internal Cypress CYUSB3304 USB hub, that shows instability due to improper reset pin configuration. Currently reset pin is modeled as a vcc5v0_host regulator, that might result in too short reset pulse duration. Starting with the v6.6, the Onboard USB hub driver (later renamed to Onboard USB dev) contains support for Cypress HX3 hub family. It can be now used to correctly model the RK3399 Puma SoM hardware. The first commits in this series fix the onboard USB dev driver to support all HX3 hub variants, including the CYUSB3304 found in the RK3399 Puma SoM. This allows to introduce fix for internal USB hub instability on RK3399 Puma, by replacing the vcc5v0_host regulator with cy3304_reset, used inside the hub node. Please be aware that the patch that fixes USB hub instability in arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi can me merged only after updating the Onboard USB dev driver, otherwise the hub will not work. Two last commits in the series disable unrouted USB controllers and PHYs on RK3399 Puma SOM and Haikou carrier board, with no intended functional changes.

[PATCH] platform/x86: dell-wmi-sysman: Avoid buffer overflow in current_password_store()

[PATCH net 0/5] hv_netvsc: Fix error "nvsp_rndis_pkt_complete error status: 2"

by mhkelley58＠gmail.com

From: Michael Kelley <mhklinux(a)outlook.com> Starting with commit dca5161f9bd0 in the 6.3 kernel, the Linux driver for Hyper-V synthetic networking (netvsc) occasionally reports "nvsp_rndis_pkt_complete error status: 2".[1] This error indicates that Hyper-V has rejected a network packet transmit request from the guest, and the outgoing network packet is dropped. Higher level network protocols presumably recover and resend the packet so there is no functional error, but performance is slightly impacted. Commit dca5161f9bd0 is not the cause of the error -- it only added reporting of an error that was already happening without any notice. The error has presumably been present since the netvsc driver was originally introduced into Linux. This patch set fixes the root cause of the problem, which is that the netvsc driver in Linux may send an incorrectly formatted VMBus message to Hyper-V when transmitting the network packet. The incorrect formatting occurs when the rndis header of the VMBus message crosses a page boundary due to how the Linux skb head memory is aligned. In such a case, two PFNs are required to describe the location of the rndis header, even though they are contiguous in guest physical address (GPA) space. Hyper-V requires that two PFNs be in a single "GPA range" data struture, but current netvsc code puts each PFN in its own GPA range, which Hyper-V rejects as an error in the case of the rndis header. The incorrect formatting occurs only for larger packets that netvsc must transmit via a VMBus "GPA Direct" message. There's no problem when netvsc transmits a smaller packet by copying it into a pre- allocated send buffer slot because the pre-allocated slots don't have page crossing issues. After commit 14ad6ed30a10 in the 6.14 kernel, the error occurs much more frequently in VMs with 16 or more vCPUs. It may occur every few seconds, or even more frequently, in a ssh session that outputs a lot of text. Commit 14ad6ed30a10 subtly changes how skb head memory is allocated, making it much more likely that the rndis header will cross a page boundary when the vCPU count is 16 or more. The changes in commit 14ad6ed30a10 are perfectly valid -- they just had the side effect of making the netvsc bug more prominent. One fix is to check for adjacent PFNs in vmbus_sendpacket_pagebuffer() and just combine them into a single GPA range. Such a fix is very contained. But conceptually it is fixing the problem at the wrong level. So this patch set takes the broader approach of maintaining the already known grouping of contiguous PFNs at a higher level in the netvsc driver code, and propagating that grouping down to the creation of the VMBus message to send to Hyper-V. Maintaining the grouping fixes this problem, and has the added benefit of allowing netvsc_dma_map() to make fewer calls to dma_map_single() to do bounce buffering in CoCo VMs. Patch 1 is a preparatory change to allow vmbus_sendpacket_mpb_desc() to specify multiple GPA ranges. In current code vmbus_sendpacket_mpb_desc() is used only by the storvsc synthetic SCSI driver, and it always creates a single GPA range. Patch 2 updates the netvsc driver to use vmbus_sendpacket_mpb_desc() instead of vmbus_sendpacket_pagebuffer(). Because the higher levels of netvsc still don't group contiguous PFNs, this patch is functionally neutral. The VMBus message to Hyper-V still has many GPA ranges, each with a single PFN. But it lays the groundwork for the next patch. Patch 3 changes the higher levels of netvsc to preserve the already known grouping of contiguous PFNs. When the contiguous groupings are passed to vmbus_sendpacket_mpb_desc(), GPA ranges containing multiple PFNs are produced, as expected by Hyper-V. This is point at which the core problem is fixed. Patches 4 and 5 remove code that is no longer necessary after the previous patches. These changes provide a net reduction of about 65 lines of code, which is an added benefit. These changes have been tested in normal VMs, in SEV-SNP and TDX CoCo VMs, and in Dv6-series VMs where the netvsp implementation is in the OpenHCL paravisor instead of the Hyper-V host. These changes are built against kernel version 6.15-rc6.
