[RFC V6 1/2] firmware: arm_scmi: Ensure that the message-id supports fastchannel

by Sibi Sankar

Currently the perf and powercap protocol relies on the protocol domain attributes, which just ensures that one fastchannel per domain, before instantiating fastchannels for all possible message-ids. Fix this by ensuring that each message-id supports fastchannel before initialization. Logs: scmi: Failed to get FC for protocol 13 [MSG_ID:6 / RES_ID:0] - ret:-95. Using regular messaging. scmi: Failed to get FC for protocol 13 [MSG_ID:6 / RES_ID:1] - ret:-95. Using regular messaging. scmi: Failed to get FC for protocol 13 [MSG_ID:6 / RES_ID:2] - ret:-95.

[PATCH] drm/xe/regs: remove a duplicate definition for RING_CTL_SIZE(size)

by Mingcong Bai

Commit b79e8fd954c4 ("drm/xe: Remove dependency on intel_engine_regs.h") introduced an internal set of engine registers, however, as part of this change, it has also introduced two duplicate `define' lines for `RING_CTL_SIZE(size)'. This commit was introduced to the tree in v6.8-rc1. While this is harmless as the definitions did not change, so no compiler warning was observed. Drop this line anyway for the sake of correctness.

This is especially easy to reproduce when the tmpfs is mount with the 'huge=within_size' parameter. Thanks to Kairui's reproducer, the issue can be easily replicated. The root cause of the problem is that swap readahead may asynchronously swap in order 0 folios into the swap cache, while the shmem mapping can still store large swap entries. Then an order 0 folio is inserted into the shmem mapping without splitting the large swap entry, which overwrites the original large swap entry, leading to data corruption. When getting a folio from the swap cache, we should split the large swap entry stored in the shmem mapping if the orders do not match, to fix this issue.

[PATCH 0/5] drm/xe: enable driver usage on non-4KiB kernels

by Mingcong Bai

This patch series attempts to enable the use of xe DRM driver on non-4KiB kernel page platforms. This involves fixing the ttm/bo interface, as well as parts of the userspace API to make use of kernel `PAGE_SIZE' for alignment instead of the assumed `SZ_4K', it also fixes incorrect usage of `PAGE_SIZE' in the GuC and ring buffer interface code to make sure all instructions/commands were aligned to 4KiB barriers (per the Programmer's Manual for the GPUs covered by this DRM driver). This issue was first discovered and reported by members of the LoongArch user communities, whose hardware commonly ran on 16KiB-page kernels. The patch series began on an unassuming branch of a downstream kernel tree maintained by Shang Yatsen.[^1] It worked well but remained sparsely documented, a lot of the work done here relied on Shang Yatsen's original patch. AOSC OS then picked it up[^2] to provide Intel Xe/Arc support for users of its LoongArch port, for which I worked extensively on. After months of positive user feedback and from encouragement from Kexy Biscuit, my colleague at the community, I decided to examine its potential for upstreaming, cross-reference kernel and Intel documentation to better document and revise this patch. Now that this series has been tested good (for boot up, OpenGL, and playback of a standardised set of video samples[^3]... with the exception of the Intel Arc B580, which seems to segfault at intel-media-driver - iHD_drv_video.so, but strangely, hardware accelerated video playback works well with Firefox?) on the following platforms (motherboard + GPU model): - x86-64, 4KiB kernel page: - MS-7D42 + Intel Arc A580 - LoongArch, 16KiB kernel page: - XA61200 + GUNNIR DG1 Blue Halberd (Intel DG1) - XA61200 + ASRock Arc A380 Challenger ITX OC (Intel Arc 380) - XA61200 + Intel Arc 580 - XA61200 + GUNNIR Intel Arc A750 Photon 8G OC (Intel Arc A750) - ASUS XC-LS3A6M + GUNNIR Intel Arc B580 INDEX 12G (Intel Arc B580) On these platforms, basic functionalities tested good but the driver was unstable with occasional resets (I do suspect however, that this platform suffers from PCIe coherence issues, as instability only occurs under heavy VRAM I/O load): - AArch64, 4KiB/64KiB kernel pages: - ERUN-FD3000 (Phytium D3000) + GUNNIR Intel Arc A750 Photon 8G OC (Intel Arc A750) I think that this patch series is now ready for your comment and review. Please forgive me if I made any simple mistake or used wrong terminologies, but I have never worked on a patch for the DRM subsystem and my experience is still quite thin. But anyway, just letting you all know that Intel Xe/Arc works on non-4KiB kernel page platforms (and honestly, it's great to use, especially for games and media playback)!

+ mm-fix-kernel-bug-when-userfaultfd_move-encounters-swapcache.patch added to mm-hotfixes-unstable branch

by Andrew Morton

The patch titled Subject: mm: fix kernel BUG when userfaultfd_move encounters swapcache has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-fix-kernel-bug-when-userfaultfd_move-encounters-swapcache.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm 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 via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Barry Song <v-songbaohua(a)oppo.com> Subject: mm: fix kernel BUG when userfaultfd_move encounters swapcache Date: Wed, 26 Feb 2025 13:14:00 +1300 userfaultfd_move() checks whether the PTE entry is present or a swap entry. - If the PTE entry is present, move_present_pte() handles folio migration by setting: src_folio->index = linear_page_index(dst_vma, dst_addr); - If the PTE entry is a swap entry, move_swap_pte() simply copies the PTE to the new dst_addr. This approach is incorrect because, even if the PTE is a swap entry, it can still reference a folio that remains in the swap cache. This creates a race window between steps 2 and 4. 1. add_to_swap: The folio is added to the swapcache. 2. try_to_unmap: PTEs are converted to swap entries. 3. pageout: The folio is written back. 4. Swapcache is cleared. If userfaultfd_move() occurs in the window between steps 2 and 4, after the swap PTE has been moved to the destination, accessing the destination triggers do_swap_page(), which may locate the folio in the swapcache. However, since the folio's index has not been updated to match the destination VMA, do_swap_page() will detect a mismatch. This can result in two critical issues depending on the system configuration. If KSM is disabled, both small and large folios can trigger a BUG during the add_rmap operation due to: page_pgoff(folio, page) != linear_page_index(vma, address) [ 13.336953] page: refcount:6 mapcount:1 mapping:00000000f43db19c index:0xffffaf150 pfn:0x4667c [ 13.337520] head: order:2 mapcount:1 entire_mapcount:0 nr_pages_mapped:1 pincount:0 [ 13.337716] memcg:ffff00000405f000 [ 13.337849] anon flags: 0x3fffc0000020459(locked|uptodate|dirty|owner_priv_1|head|swapbacked|node=0|zone=0|lastcpupid=0xffff) [ 13.338630] raw: 03fffc0000020459 ffff80008507b538 ffff80008507b538 ffff000006260361 [ 13.338831] raw: 0000000ffffaf150 0000000000004000 0000000600000000 ffff00000405f000 [ 13.339031] head: 03fffc0000020459 ffff80008507b538 ffff80008507b538 ffff000006260361 [ 13.339204] head: 0000000ffffaf150 0000000000004000 0000000600000000 ffff00000405f000 [ 13.339375] head: 03fffc0000000202 fffffdffc0199f01 ffffffff00000000 0000000000000001 [ 13.339546] head: 0000000000000004 0000000000000000 00000000ffffffff 0000000000000000 [ 13.339736] page dumped because: VM_BUG_ON_PAGE(page_pgoff(folio, page) != linear_page_index(vma, address)) [ 13.340190] ------------[ cut here ]------------ [ 13.340316] kernel BUG at mm/rmap.c:1380!

This patch also checks the swapcache when handling swap entries. If a match is found in the swapcache, it processes it similarly to a present PTE. However, there are some differences. For example, the folio is no longer exclusive because folio_try_share_anon_rmap_pte() is performed during unmapping. Furthermore, in the case of swapcache, the folio has already been unmapped, eliminating the risk of concurrent rmap walks and removing the need to acquire src_folio's anon_vma or lock. Note that for large folios, in the swapcache handling path, we directly return -EBUSY since split_folio() will return -EBUSY regardless if the folio is under writeback or unmapped. This is not an urgent issue, so a follow-up patch may address it separately.

[PATCH V2] drm/sched: fix fence reference count leak

by Qianyi Liu

From: qianyi liu <liuqianyi125(a)gmail.com> We leaked last_scheduled fences when the entity was being killed and the fence callback add fails. To fix this, we should decrement the reference count of prev when dma_fence_add_callback() fails, ensuring proper balance. v2: * Make commit message more clearly.

To give time for DAMON to make changes for the regions, 3 aggregation intervals (300 milliseconds) are given. The internal mechanism works with not only the max_nr_regions, but also sz_limit, though. It avoids merging region if that casn make region of size larger than sz_limit. In the test, sz_limit is set too small to achive the new max_nr_regions, unless it is updated for the new min_nr_regions. But the update is done only once per operations set update interval, which is one second by default. Hence, the test randomly incurs false positive failures. Fix it by setting the ops interval same to aggregation interval, to make sure sz_limit is updated by the time of the check.

Fix three DAMON selftest bugs that cause two and one false positive failures and successes. This patch (of 3): damos_quota.py assumes the quota will always exceeded.

[PATCH] drm/amd/display: Fix null check for pipe_ctx->plane_state in resource_build_scaling_params

by Ma Ke

Null pointer dereference issue could occur when pipe_ctx->plane_state is null. The fix adds a check to ensure 'pipe_ctx->plane_state' is not null before accessing. This prevents a null pointer dereference. Found by code review.

[PATCH] USB: core: Enable root_hub's remote wakeup for wakeup sources

by Huacai Chen

Now we only enable the remote wakeup function for the USB wakeup source itself at usb_port_suspend(). But on pre-XHCI controllers this is not enough to enable the S3 wakeup function for USB keyboards, so we also enable the root_hub's remote wakeup (and disable it on error). Frankly this is unnecessary for XHCI, but enable it unconditionally make code simple and seems harmless.

[PATCH 2/3] selftests/damon/damon_nr_regions: set ops update for merge results check to 100ms

by SeongJae Park

damon_nr_regions.py updates max_nr_regions to a number smaller than expected number of real regions and confirms DAMON respect the harsh limit. To give time for DAMON to make changes for the regions, 3 aggregation intervals (300 milliseconds) are given. The internal mechanism works with not only the max_nr_regions, but also sz_limit, though. It avoids merging region if that casn make region of size larger than sz_limit. In the test, sz_limit is set too small to achive the new max_nr_regions, unless it is updated for the new min_nr_regions. But the update is done only once per operations set update interval, which is one second by default. Hence, the test randomly incurs false positive failures. Fix it by setting the ops interval same to aggregation interval, to make sure sz_limit is updated by the time of the check.

[PATCH 01/19] drm/i915/cdclk: Do cdclk post plane programming later

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> We currently call intel_set_cdclk_post_plane_update() far too early. When pipes are active during the reprogramming the current spot only works for the cd2x divider update case, as that is synchronize to the pipe's vblank. Squashing and crawling are not synchronized in any way, so doing the programming while the pipes/planes are potentially still using the old hardware state could lead to underruns. Move the post plane reprgramming to a spot where we know that the pipes/planes have switched over the new hardware state.

[PATCH v2 3/5] phy: renesas: rcar-gen3-usb2: Lock around hardware registers and driver data

by Claudiu

From: Claudiu Beznea <claudiu.beznea.uj(a)bp.renesas.com> The phy-rcar-gen3-usb2 driver exposes four individual PHYs that are requested and configured by PHY users. The struct phy_ops APIs access the same set of registers to configure all PHYs. Additionally, PHY settings can be modified through sysfs or an IRQ handler. While some struct phy_ops APIs are protected by a driver-wide mutex, others rely on individual PHY-specific mutexes. This approach can lead to various issues, including: 1/ the IRQ handler may interrupt PHY settings in progress, racing with hardware configuration protected by a mutex lock 2/ due to msleep(20) in rcar_gen3_init_otg(), while a configuration thread suspends to wait for the delay, another thread may try to configure another PHY (with phy_init() + phy_power_on()); re-running the phy_init() goes to the exact same configuration code, re-running the same hardware configuration on the same set of registers (and bits) which might impact the result of the msleep for the 1st configuring thread 3/ sysfs can configure the hardware (though role_store()) and it can still race with the phy_init()/phy_power_on() APIs calling into the drivers struct phy_ops To address these issues, add a spinlock to protect hardware register access and driver private data structures (e.g., calls to rcar_gen3_is_any_rphy_initialized()). Checking driver-specific data remains necessary as all PHY instances share common settings. With this change, the existing mutex protection is removed and the cleanup.h helpers are used. While at it, to keep the code simpler, do not skip regulator_enable()/regulator_disable() APIs in rcar_gen3_phy_usb2_power_on()/rcar_gen3_phy_usb2_power_off() as the regulators enable/disable operations are reference counted anyway.

This issue occurs when PHY 3 is the first initialized PHY. PHY 3 does not have an interrupt associated with the USB2_INT_ENABLE register (as rcar_gen3_int_enable[3] = 0). As a result, rcar_gen3_init_otg() is called to initialize OTG without enabling PHY interrupts. To resolve this, add rcar_gen3_is_any_otg_rphy_initialized() and call it in role_store(), role_show(), and rcar_gen3_init_otg(). At the same time, rcar_gen3_init_otg() is only called when initialization for a PHY with interrupt bits is in progress. As a result, the struct rcar_gen3_phy::otg_initialized is no longer needed.

[PATCH v2] drm/msm/a6xx: Fix stale rpmh votes from GPU

by Akhil P Oommen

It was observed on sc7180 (A618 gpu) that GPU votes for GX rail and CNOC BCM nodes were not removed after GPU suspend. This was because we skipped sending 'prepare-slumber' request to gmu during suspend sequence in some cases. So, make sure we always call prepare-slumber hfi during suspend. Also, calling prepare-slumber without a prior oob-gpu handshake messes up gmu firmware's internal state. So, do that when required.

However, this flag differs from others in that it is used as an indicator for whether the driver is ready to perform the ndo_xdp_xmit operation as part of an XDP_REDIRECT. Kernel helpers xdp_features_(set|clear)_redirect_target exist to convey this meaning. This patch ensures that the netdev is only reported as a redirect target when XDP queues exist to forward traffic.

[PATCH v6.1-v5.4 1/1] pfifo_tail_enqueue: Drop new packet when sch->limit == 0

by Lee Jones

[ Upstream commit 647cef20e649c576dff271e018d5d15d998b629d ] Expected behaviour: In case we reach scheduler's limit, pfifo_tail_enqueue() will drop a packet in scheduler's queue and decrease scheduler's qlen by one. Then, pfifo_tail_enqueue() enqueue new packet and increase scheduler's qlen by one. Finally, pfifo_tail_enqueue() return `NET_XMIT_CN` status code. Weird behaviour: In case we set `sch->limit == 0` and trigger pfifo_tail_enqueue() on a scheduler that has no packet, the 'drop a packet' step will do nothing. This means the scheduler's qlen still has value equal 0. Then, we continue to enqueue new packet and increase scheduler's qlen by one. In summary, we can leverage pfifo_tail_enqueue() to increase qlen by one and return `NET_XMIT_CN` status code. The problem is: Let's say we have two qdiscs: Qdisc_A and Qdisc_B. - Qdisc_A's type must have '->graft()' function to create parent/child relationship. Let's say Qdisc_A's type is `hfsc`. Enqueue packet to this qdisc will trigger `hfsc_enqueue`. - Qdisc_B's type is pfifo_head_drop. Enqueue packet to this qdisc will trigger `pfifo_tail_enqueue`. - Qdisc_B is configured to have `sch->limit == 0`. - Qdisc_A is configured to route the enqueued's packet to Qdisc_B. Enqueue packet through Qdisc_A will lead to: - hfsc_enqueue(Qdisc_A) -> pfifo_tail_enqueue(Qdisc_B) - Qdisc_B->q.qlen += 1 - pfifo_tail_enqueue() return `NET_XMIT_CN` - hfsc_enqueue() check for `NET_XMIT_SUCCESS` and see `NET_XMIT_CN` => hfsc_enqueue() don't increase qlen of Qdisc_A. The whole process lead to a situation where Qdisc_A->q.qlen == 0 and Qdisc_B->q.qlen == 1. Replace 'hfsc' with other type (for example: 'drr') still lead to the same problem. This violate the design where parent's qlen should equal to the sum of its childrens'qlen. Bug impact: This issue can be used for user->kernel privilege escalation when it is reachable.

[BUG] r8188eu: Potential deadlocks in rtw_wx_set_wap/essid functions

by Gui-Dong Han

Hello maintainers, I would like to report a potential lock ordering issue in the r8188eu driver. This may lead to deadlocks under certain conditions. The functions rtw_wx_set_wap() and rtw_wx_set_essid() acquire locks in an order that contradicts the established locking hierarchy observed in other parts of the driver: 1. They first take &pmlmepriv->scanned_queue.lock 2. Then call rtw_set_802_11_infrastructure_mode() which takes &pmlmepriv->lock This is inverted compared to the common pattern seen in functions like rtw_joinbss_event_prehandle(), rtw_createbss_cmd_callback(), and others, which typically: 1. Take &pmlmepriv->lock first 2. Then take &pmlmepriv->scanned_queue.lock This lock inversion creates a potential deadlock scenario when these code paths execute concurrently. Moreover, the call chain: rtw_wx_set_* -> rtw_set_802_11_infrastructure_mode() -> rtw_free_assoc_resources() could lead to recursive acquisition of &pmlmepriv->scanned_queue.lock, potentially causing self-deadlock even without concurrency. This issue exists in longterm kernels containing the r8188eu driver: 5.4.y (until 5.4.290) 5.10.y (until 5.10.234) 5.15.y (until 5.15.178) 6.1.y (until 6.1.129) The r8188eu driver has been removed from upstream, but older maintained versions (5.4.x–6.1.x) still include this driver and are affected. This issue was identified through static analysis. While I've verified the locking patterns through code review, I'm not sufficiently familiar with the driver's internals to propose a safe fix. Thank you for your attention to this matter. Best regards, Gui-Dong Han

[PATCH 1/3] perf/x86: Fix low freq setting issue

From: Kan Liang <kan.liang(a)linux.intel.com> Perf doesn't work with a low freq. perf record -e cpu_core/instructions/ppp -F 120 Error: The sys_perf_event_open() syscall returned with 22 (Invalid argument) for event (cpu_core/instructions/ppp). "dmesg | grep -i perf" may provide additional information. The limit_period() check avoids a low sampling period on a counter. It doesn't intend to limit the frequency.

[PATCH 0/8] gpiolib: sanitize return values of callbacks

We've had instances of drivers returning invalid values from gpio_chip calbacks. In several cases these return values would be propagated to user-space and confuse programs that only expect 0 or negative errnos from ioctl()s.

[PATCH v4 1/5] KVM: arm64: Set HCR_EL2.TID1 unconditionally

by Oliver Upton

commit 90807748ca3a ("KVM: arm64: Hide SME system registers from guests") added trap handling for SMIDR_EL1, treating it as UNDEFINED as KVM does not support SME. This is right for the most part, however KVM needs to set HCR_EL2.TID1 to _actually_ trap the register. Unfortunately, this comes with some collateral damage as TID1 forces REVIDR_EL1 and AIDR_EL1 to trap as well. KVM has long treated these registers as "invariant" which is an awful term for the following: - Userspace sees the boot CPU values on all vCPUs - The guest sees the hardware values of the CPU on which a vCPU is scheduled Keep the plates spinning by adding trap handling for the affected registers and repaint all of the "invariant" crud into terms of identifying an implementation. Yes, at this point we only need to set TID1 on SME hardware, but REVIDR_EL1 and AIDR_EL1 are about to become mutable anyway.

[PATCH v4 3/6] misc: pci_endpoint_test: Fix displaying irq_type after request_irq error

by Kunihiko Hayashi

There are two variables that indicate the interrupt type to be used in the next test execution, global "irq_type" and test->irq_type. The former is referenced from pci_endpoint_test_get_irq() to preserve the current type for ioctl(PCITEST_GET_IRQTYPE). In pci_endpoint_test_request_irq(), since this global variable is referenced when an error occurs, the unintended error message is displayed. For example, the following message shows "MSI 3" even if the current irq type becomes "MSI-X". # pcitest -i 2 pci-endpoint-test 0000:01:00.0: Failed to request IRQ 30 for MSI 3 SET IRQ TYPE TO MSI-X: NOT OKAY Fix this issue by using test->irq_type instead of global "irq_type".

[PATCH v4 2/6] misc: pci_endpoint_test: Avoid issue of interrupts remaining after request_irq error

by Kunihiko Hayashi

After devm_request_irq() fails with error in pci_endpoint_test_request_irq(), pci_endpoint_test_free_irq_vectors() is called assuming that all IRQs have been released. However some requested IRQs remain unreleased, so there are still /proc/irq/* entries remaining and this results in WARN() with the following message: remove_proc_entry: removing non-empty directory 'irq/30', leaking at least 'pci-endpoint-test.0' WARNING: CPU: 0 PID: 202 at fs/proc/generic.c:719 remove_proc_entry +0x190/0x19c To solve this issue, set the number of remaining IRQs to test->num_irqs and release IRQs in advance by calling pci_endpoint_test_release_irq().

[PATCH 1/1] usb: xhci: Enable the TRB overfetch quirk on VIA VL805

by Mathias Nyman

From: Michal Pecio <michal.pecio(a)gmail.com> Raspberry Pi is a major user of those chips and they discovered a bug - when the end of a transfer ring segment is reached, up to four TRBs can be prefetched from the next page even if the segment ends with link TRB and on page boundary (the chip claims to support standard 4KB pages). It also appears that if the prefetched TRBs belong to a different ring whose doorbell is later rung, they may be used without refreshing from system RAM and the endpoint will stay idle if their cycle bit is stale. Other users complain about IOMMU faults on x86 systems, unsurprisingly. Deal with it by using existing quirk which allocates a dummy page after each transfer ring segment. This was seen to resolve both problems. RPi came up with a more efficient solution, shortening each segment by four TRBs, but it complicated the driver and they ditched it for this quirk. Also rename the quirk and add VL805 device ID macro.

[PATCH] x86/vmemmap: Synchronize with global pgds if populating init_mm's pgd

by Gwan-gyeong Mun

Address an Oops issues when performing test of loading XE GPU driver module after applying the GPU SVM and Xe SVM patch series[1] and the Dept patch series[2]. The issue occurs when loading the xe driver via modprobe [3], which adds a struct page for device memory via devm_memremap_pages(). When a process leads the addition of a struct page to vmemmap (e.g. hot-plug), the page table update for the newly added vmemmap-based virtual address is updated first in init_mm's page table and then synchronized later. If the vmemmap-based virtual address is accessed through the process's page table before this sync, a page fault will occur. This addresses the issue by synchronizing with the global pgds immediately after populating the init_mm's pgd. On platforms other than the x86 platform, there is currently no case of accessing the address before synchronizing the pgd, so applying the weak symbol to existing vmemmap_pgd_populate() and vmemmap_pgd_populate(), and adding a strong- symbol function to x86 so that only the x86 platform have this behavior.

[PATCH 1/5] drm/xe/regs: remove a duplicate definition for RING_CTL_SIZE(size)

by Mingcong Bai

Commit b79e8fd954c4 ("drm/xe: Remove dependency on intel_engine_regs.h") introduced an internal set of engine registers, however, as part of this change, it has also introduced two duplicate `define' lines for `RING_CTL_SIZE(size)'. This commit was introduced to the tree in v6.8-rc1. While this is harmless as the definitions did not change, so no compiler warning was observed. Drop this line anyway for the sake of correctness.

[PATCH v6 1/3] x86/paravirt: Move halt paravirt calls under CONFIG_PARAVIRT

by Vishal Annapurve

From: "Kirill A. Shutemov" <kirill.shutemov(a)linux.intel.com> CONFIG_PARAVIRT_XXL is mainly defined/used by XEN PV guests. For other VM guest types, features supported under CONFIG_PARAVIRT are self sufficient. CONFIG_PARAVIRT mainly provides support for TLB flush operations and time related operations. For TDX guest as well, paravirt calls under CONFIG_PARVIRT meets most of its requirement except the need of HLT and SAFE_HLT paravirt calls, which is currently defined under CONFIG_PARAVIRT_XXL. Since enabling CONFIG_PARAVIRT_XXL is too bloated for TDX guest like platforms, move HLT and SAFE_HLT paravirt calls under CONFIG_PARAVIRT. Moving HLT and SAFE_HLT paravirt calls are not fatal and should not break any functionality for current users of CONFIG_PARAVIRT.

[PATCH v2 RESEND] phy: Fix error handling in tegra_xusb_port_init

by Ma Ke

If device_add() fails, do not use device_unregister() for error handling. device_unregister() consists two functions: device_del() and put_device(). device_unregister() should only be called after device_add() succeeded because device_del() undoes what device_add() does if successful. Change device_unregister() to put_device() call before returning from the function. As comment of device_add() says, 'if device_add() succeeds, you should call device_del() when you want to get rid of it. If device_add() has not succeeded, use only put_device() to drop the reference count'. Found by code review.

[PATCH] dlm: fix lkb timeout scanning lookup

by Alexander Aring

If a lkb is timed out when dlm_scan_timeout() kicks in and removes a timed out lkb from ls->ls_timeout list the next iteration can end in timeout the same lkb again that shouldn't happen. Since commit dc1acd5c9469 ("dlm: replace usage of found with dedicated list iterator variable") we don't set the lkb variable before the inner lookup loop to NULL. The outer loop will not stop and checks if there was a successful lookup with the lkb pointer of the last iteration that wasn't set to NULL. To stop this behavior we use the old condition "!do_cancel && !do_warn" which signals if there was a successful lookup and the lkb variable should be set with the lkb that was looked up to be timed out. If the condition is false there is no timed out lkb in ls->ls_timeout and the outer loop stops.

[PATCH AUTOSEL 6.12 01/28] bpf: unify VM_WRITE vs VM_MAYWRITE use in BPF map mmaping logic

by Sasha Levin

From: Andrii Nakryiko <andrii(a)kernel.org> [ Upstream commit 98671a0fd1f14e4a518ee06b19037c20014900eb ] For all BPF maps we ensure that VM_MAYWRITE is cleared when memory-mapping BPF map contents as initially read-only VMA. This is because in some cases BPF verifier relies on the underlying data to not be modified afterwards by user space, so once something is mapped read-only, it shouldn't be re-mmap'ed as read-write. As such, it's not necessary to check VM_MAYWRITE in bpf_map_mmap() and map->ops->map_mmap() callbacks: VM_WRITE should be consistently set for read-write mappings, and if VM_WRITE is not set, there is no way for user space to upgrade read-only mapping to read-write one. This patch cleans up this VM_WRITE vs VM_MAYWRITE handling within bpf_map_mmap(), which is an entry point for any BPF map mmap()-ing logic. We also drop unnecessary sanitization of VM_MAYWRITE in BPF ringbuf's map_mmap() callback implementation, as it is already performed by common code in bpf_map_mmap(). Note, though, that in bpf_map_mmap_{open,close}() callbacks we can't drop VM_MAYWRITE use, because it's possible (and is outside of subsystem's control) to have initially read-write memory mapping, which is subsequently dropped to read-only by user space through mprotect(). In such case, from BPF verifier POV it's read-write data throughout the lifetime of BPF map, and is counted as "active writer". But its VMAs will start out as VM_WRITE|VM_MAYWRITE, then mprotect() can change it to just VM_MAYWRITE (and no VM_WRITE), so when its finally munmap()'ed and bpf_map_mmap_close() is called, vm_flags will be just VM_MAYWRITE, but we still need to decrement active writer count with bpf_map_write_active_dec() as it's still considered to be a read-write mapping by the rest of BPF subsystem. Similar reasoning applies to bpf_map_mmap_open(), which is called whenever mmap(), munmap(), and/or mprotect() forces mm subsystem to split original VMA into multiple discontiguous VMAs.

[PATCH] mtd: Fix potential UAF for mtdswap_dev pointers

by Ma Ke

In the mtdswap_init(), if the allocations fail, the error handling path frees d->page_buf, d->eb_data, d->revmap and d->page_data without setting these pointers to NULL. This could lead to UAF if subsequent error handling or device reset operations attempt to release these pointers again. Set d->page_buf, d->eb_data, d->revmap and d->page_data to NULL immediately after freeing them to prevent misuse. Release immediately and set to NULL, adhering to the 'release implies invalid' defensive programming principle. Found by code review.

[PATCH] drm/amd/display: Disable unneeded hpd interrupts during dm_init

by sunpeng.li＠amd.com

From: Leo Li <sunpeng.li(a)amd.com> [Why] It seems HPD interrupts are enabled by default for all connectors, even if the hpd source isn't valid. An eDP for example, does not have a valid hpd source (but does have a valid hpdrx source; see construct_phy()). Thus, eDPs should have their hpd interrupt disabled. In the past, this wasn't really an issue. Although the driver gets interrupted, then acks by writing to hw registers, there weren't any subscribed handlers that did anything meaningful (see register_hpd_handlers()). But things changed with the introduction of IPS. s2idle requires that the driver allows IPS for DMUB fw to put hw to sleep. Since register access requires hw to be awake, the driver will block IPS entry to do so. And no IPS means no hw sleep during s2idle. This was the observation on DCN35 systems with an eDP. During suspend, the eDP toggled its hpd pin as part of the panel power down sequence. The driver was then interrupted, and acked by writing to registers, blocking IPS entry. [How] Since DC marks eDP connections as having invalid hpd sources (see construct_phy()), DM should disable them at the hw level. Do so in amdgpu_dm_hpd_init() by disabling all hpd ints first, then selectively enabling ones for connectors that have valid hpd sources.

This requirement is a bitstring sent from the VIOS which maps to the type of header information needed during TX. If no header information, is needed then send subcrq direct can be used (which can be more performant). This bitstring was previously ignored for standard packets (AKA non LSO, non CSO) due to the belief that the bitstring was over-cautionary. It turns out that there are some configurations where the backing device does need header information for transmission of standard packets. If the information is not supplied then this causes continuous "Adapter error" transport events. Therefore, this bitstring should be respected and observed before considering the use of send subcrq direct.

This requirement is a bitstring sent from the VIOS which maps to the type of header information needed during TX. If no header information, is needed then send subcrq direct can be used (which can be more performant). This bitstring was previously ignored for standard packets (AKA non LSO, non CSO) due to the belief that the bitstring was over-cautionary. It turns out that there are some configurations where the backing device does need header information for transmission of standard packets. If the information is not supplied then this causes continuous "Adapter error" transport events. Therefore, this bitstring should be respected and observed before considering the use of send subcrq direct.

[PATCH 6.1.y] ssb: Fix potential NULL pointer dereference in ssb_device_uevent()

by jianqi.ren.cn＠windriver.com

From: Rand Deeb <rand.sec96(a)gmail.com> [ Upstream commit 789c17185fb0f39560496c2beab9b57ce1d0cbe7 ] The ssb_device_uevent() function first attempts to convert the 'dev' pointer to 'struct ssb_device *'. However, it mistakenly dereferences 'dev' before performing the NULL check, potentially leading to a NULL pointer dereference if 'dev' is NULL. To fix this issue, move the NULL check before dereferencing the 'dev' pointer, ensuring that the pointer is valid before attempting to use it.

[PATCH 6.6.y] net/mlx5e: Don't call cleanup on profile rollback failure

by jianqi.ren.cn＠windriver.com

From: Cosmin Ratiu <cratiu(a)nvidia.com> [ Upstream commit 4dbc1d1a9f39c3711ad2a40addca04d07d9ab5d0 ] When profile rollback fails in mlx5e_netdev_change_profile, the netdev profile var is left set to NULL. Avoid a crash when unloading the driver by not calling profile->cleanup in such a case. This was encountered while testing, with the original trigger that the wq rescuer thread creation got interrupted (presumably due to Ctrl+C-ing modprobe), which gets converted to ENOMEM (-12) by mlx5e_priv_init, the profile rollback also fails for the same reason (signal still active) so the profile is left as NULL, leading to a crash later in _mlx5e_remove.

[PATCH v3] serial: 8250: Fix fifo underflow on flush

by John Keeping

When flushing the serial port's buffer, uart_flush_buffer() calls kfifo_reset() but if there is an outstanding DMA transfer then the completion function will consume data from the kfifo via uart_xmit_advance(), underflowing and leading to ongoing DMA as the driver tries to transmit another 2^32 bytes.

[PATCH v2] acpi: nfit: fix narrowing conversion in acpi_nfit_ctl

It is important that this function expects that the argument is between 1 and NVDIMM_BUS_FAMILY_MAX. Therefore, it must be checked beforehand. However, in acpi_nfit_ctl() validity checks made before calling to_nfit_bus_uuid() are erroneous. Function acpi_nfit_ctl() first verifies that a user-provided value call_pkg->nd_family of type u64 is not equal to 0. Then the value is converted to int (narrowing conversion), and only after that is compared to NVDIMM_BUS_FAMILY_MAX. This can lead to passing an invalid argument to acpi_nfit_ctl(), if call_pkg->nd_family is non-zero, while the lower 32 bits are zero. Moreover, the same way zero can be passed in to_nfit_bus_uuid(), negative value also may occur. That wouldn't trigger the warning, but could lead to a wild-memory-access in test_bit(). This is achieved with a slightly modified version of the reproducer generated by Syzkaller.

[PATCH AUTOSEL 5.4 1/4] ASoC: rsnd: don't indicate warning on rsnd_kctrl_accept_runtime()

by Sasha Levin

Now, rsnd driver has 2 kctrls for it (A): "SRC Out Rate Switch" (B): "SRC Out Rate" // it calls (1) (A): can be called anytime (B): can be called only runtime, and will indicate warning if it was used at non-runtime.

[PATCH AUTOSEL 6.6 01/20] bpf: unify VM_WRITE vs VM_MAYWRITE use in BPF map mmaping logic

by Sasha Levin

From: Andrii Nakryiko <andrii(a)kernel.org> [ Upstream commit 98671a0fd1f14e4a518ee06b19037c20014900eb ] For all BPF maps we ensure that VM_MAYWRITE is cleared when memory-mapping BPF map contents as initially read-only VMA. This is because in some cases BPF verifier relies on the underlying data to not be modified afterwards by user space, so once something is mapped read-only, it shouldn't be re-mmap'ed as read-write. As such, it's not necessary to check VM_MAYWRITE in bpf_map_mmap() and map->ops->map_mmap() callbacks: VM_WRITE should be consistently set for read-write mappings, and if VM_WRITE is not set, there is no way for user space to upgrade read-only mapping to read-write one. This patch cleans up this VM_WRITE vs VM_MAYWRITE handling within bpf_map_mmap(), which is an entry point for any BPF map mmap()-ing logic. We also drop unnecessary sanitization of VM_MAYWRITE in BPF ringbuf's map_mmap() callback implementation, as it is already performed by common code in bpf_map_mmap(). Note, though, that in bpf_map_mmap_{open,close}() callbacks we can't drop VM_MAYWRITE use, because it's possible (and is outside of subsystem's control) to have initially read-write memory mapping, which is subsequently dropped to read-only by user space through mprotect(). In such case, from BPF verifier POV it's read-write data throughout the lifetime of BPF map, and is counted as "active writer". But its VMAs will start out as VM_WRITE|VM_MAYWRITE, then mprotect() can change it to just VM_MAYWRITE (and no VM_WRITE), so when its finally munmap()'ed and bpf_map_mmap_close() is called, vm_flags will be just VM_MAYWRITE, but we still need to decrement active writer count with bpf_map_write_active_dec() as it's still considered to be a read-write mapping by the rest of BPF subsystem. Similar reasoning applies to bpf_map_mmap_open(), which is called whenever mmap(), munmap(), and/or mprotect() forces mm subsystem to split original VMA into multiple discontiguous VMAs. Memory-mapping handling is a bit tricky, yes.

Using cmn_interrupt_2_enable to configure Tag, Data RAM ECC interrupts would lead to issues like double handling of the interrupts (EL1 and EL3) as cmn_interrupt_2_enable is meant to be configured for interrupts which needs to be handled by EL3. EL1 LLCC EDAC driver needs to use cmn_interrupt_0_enable register to configure Tag, Data RAM ECC interrupts instead of cmn_interrupt_2_enable.

Commit a18280e7fdea ("smb: cilent: set reparse mount points as automounts") mistakenly removed the @data NULL check when calling is_inode_cache_good(), which broke the above case as the new ATTR_READONLY attribute would end up not being updated on files with a read lease. Fix this by updating the inode whenever we have cached metadata in @data parameter.

Wong" <djwong(a)kernel.org> Date: Sun, 2 Feb 2025 16:50:14 -0800 Subject: [PATCH] xfs: fix online repair probing when CONFIG_XFS_ONLINE_REPAIR=n I received a report from the release engineering side of the house that xfs_scrub without the -n flag (aka fix it mode) would try to fix a broken filesystem even on a kernel that doesn't have online repair built into it: # xfs_scrub -dTvn /mnt/test EXPERIMENTAL xfs_scrub program in use! Use at your own risk! Phase 1: Find filesystem geometry. /mnt/test: using 1 threads to scrub. Phase 1: Memory used: 132k/0k (108k/25k), time: 0.00/ 0.00/ 0.00s <snip> Phase 4: Repair filesystem. <snip> Info: /mnt/test/some/victimdir directory entries: Attempting repair. (repair.c line 351) Corruption: /mnt/test/some/victimdir directory entries: Repair unsuccessful; offline repair required. (repair.c line 204) Source: https://blogs.oracle.com/linux/post/xfs-online-filesystem-repair It is strange that xfs_scrub doesn't refuse to run, because the kernel is supposed to return EOPNOTSUPP if we actually needed to run a repair, and xfs_io's repair subcommand will perror that. And yet: # xfs_io -x -c 'repair probe' /mnt/test # The first problem is commit dcb660f9222fd9 (4.15) which should have had xchk_probe set the CORRUPT OFLAG so that any of the repair machinery will get called at all. It turns out that some refactoring that happened in the 6.6-6.8 era broke the operation of this corner case. What we *really* want to happen is that all the predicates that would steer xfs_scrub_metadata() towards calling xrep_attempt() should function the same way that they do when repair is compiled in; and then xrep_attempt gets to return the fatal EOPNOTSUPP error code that causes the probe to fail. Instead, commit 8336a64eb75cba (6.6) started the failwhale swimming by hoisting OFLAG checking logic into a helper whose non-repair stub always returns false, causing scrub to return "repair not needed" when in fact the repair is not supported. Prior to that commit, the oflag checking that was open-coded in scrub.c worked correctly. Similarly, in commit 4bdfd7d15747b1 (6.8) we hoisted the IFLAG_REPAIR and ALREADY_FIXED logic into a helper whose non-repair stub always returns false, so we never enter the if test body that would have called xrep_attempt, let alone fail to decode the OFLAGs correctly. The final insult (yes, we're doing The Naked Gun now) is commit 48a72f60861f79 (6.8) in which we hoisted the "are we going to try a repair?" predicate into yet another function with a non-repair stub always returns false. Fix xchk_probe to trigger xrep_probe if repair is enabled, or return EOPNOTSUPP directly if it is not. For all the other scrub types, we need to fix the header predicates so that the ->repair functions (which are all xrep_notsupported) get called to return EOPNOTSUPP. Commit 48a72 is tagged here because the scrub code prior to LTS 6.12 are incomplete and not worth patching.

[PATCH] agp: Fix a potential memory leak bug in agp_amdk7_probe()

by Haoxiang Li

Re: REGRESSION amdgpu 20241108 firmware breaks screen updating

I can confirm amdgpu.dcdebugmask=0x200 fixes it, no more stutters.

[PATCH v2] usb: gadget: Set self-powered based on MaxPower and bmAttributes

by Prashanth K

Currently the USB gadget will be set as bus-powered based solely on whether its bMaxPower is greater than 100mA, but this may miss devices that may legitimately draw less than 100mA but still want to report as bus-powered. Similarly during suspend & resume, USB gadget is incorrectly marked as bus/self powered without checking the bmAttributes field. Fix these by configuring the USB gadget as self or bus powered based on bmAttributes, and explicitly set it as bus-powered if it draws more than 100mA.

[PATCH] USB: Skip resume if pm_runtime_set_active() fails

by Ma Ke

A race condition occurs during system suspend if interrupted between usb_suspend() and the parent device’s PM suspend (e.g., a power domain). This triggers PM resume workflows (via usb_resume()), but if parent device is already runtime-suspended, pm_runtime_set_active() fails. Subsequent operations like pm_runtime_enable() and interface unbinding may leave the USB device in an inconsistent state or trigger unintended behavior. Found by code review.

[PATCH] mm: abort vma_modify() on merge out of memory failure

by Lorenzo Stoakes

The remainder of vma_modify() relies upon the vmg state remaining pristine after a merge attempt. Usually this is the case, however in the one edge case scenario of a merge attempt failing not due to the specified range being unmergeable, but rather due to an out of memory error arising when attempting to commit the merge, this assumption becomes untrue. This results in vmg->start, end being modified, and thus the proceeding attempts to split the VMA will be done with invalid start/end values. Thankfully, it is likely practically impossible for us to hit this in reality, as it would require a maple tree node pre-allocation failure that would likely never happen due to it being 'too small to fail', i.e. the kernel would simply keep retrying reclaim until it succeeded. However, this scenario remains theoretically possible, and what we are doing here is wrong so we must correct it. The safest option is, when this scenario occurs, to simply give up the operation. If we cannot allocate memory to merge, then we cannot allocate memory to split either (perhaps moreso!). Any scenario where this would be happening would be under very extreme (likely fatal) memory pressure, so it's best we give up early. So there is no doubt it is appropriate to simply bail out in this scenario. However, in general we must if at all possible never assume VMG state is stable after a merge attempt, since merge operations update VMG fields. As a result, additionally also make this clear by storing start, end in local variables. The issue was reported originally by syzkaller, and by Brad Spengler (via an off-list discussion), and in both instances it manifested as a triggering of the assert: VM_WARN_ON_VMG(start >= end, vmg); In vma_merge_existing_range(). It seems at least one scenario in which this is occurring is one in which the merge being attempted is due to an madvise() across multiple VMAs which looks like this: start end |<------>| |----------|------| | vma | next | |----------|------| When madvise_walk_vmas() is invoked, we first find vma in the above (determining prev to be equal to vma as we are offset into vma), and then enter the loop. We determine the end of vma that forms part of the range we are madvise()'ing by setting 'tmp' to this value: /* Here vma->vm_start <= start < (end|vma->vm_end) */ tmp = vma->vm_end; We then invoke the madvise() operation via visit(), letting prev get updated to point to vma as part of the operation: /* Here vma->vm_start <= start < tmp <= (end|vma->vm_end). */ error = visit(vma, &prev, start, tmp, arg); Where the visit() function pointer in this instance is madvise_vma_behavior(). As observed in syzkaller reports, it is ultimately madvise_update_vma() that is invoked, calling vma_modify_flags_name() and vma_modify() in turn. Then, in vma_modify(), we attempt the merge: merged = vma_merge_existing_range(vmg); if (merged) return merged; We invoke this with vmg->start, end set to start, tmp as such: start tmp |<--->| |----------|------| | vma | next | |----------|------| We find ourselves in the merge right scenario, but the one in which we cannot remove the middle (we are offset into vma). Here we have a special case where vmg->start, end get set to perhaps unintuitive values - we intended to shrink the middle VMA and expand the next. This means vmg->start, end are set to... vma->vm_start, start. Now the commit_merge() fails, and vmg->start, end are left like this. This means we return to the rest of vma_modify() with vmg->start, end (here denoted as start', end') set as: start' end' |<-->| |----------|------| | vma | next | |----------|------| So we now erroneously try to split accordingly. This is where the unfortunate stuff begins. We start with: /* Split any preceding portion of the VMA. */ if (vma->vm_start < vmg->start) { ... } This doesn't trigger as we are no longer offset into vma at the start. But then we invoke: /* Split any trailing portion of the VMA. */ if (vma->vm_end > vmg->end) { ... } Which does get invoked. This leaves us with: start' end' |<-->| |----|-----|------| | vma| new | next | |----|-----|------| We then return ultimately to madvise_walk_vmas(). Here 'new' is unknown, and putting back the values known in this function we are faced with: start tmp end | | | |----|-----|------| | vma| new | next | |----|-----|------| prev Then: start = tmp; So: start end | | |----|-----|------| | vma| new | next | |----|-----|------| prev The following code does not cause anything to happen: if (prev && start < prev->vm_end) start = prev->vm_end; if (start >= end) break; And then we invoke: if (prev) vma = find_vma(mm, prev->vm_end); Which is where a problem occurs - we don't know about 'new' so we essentially look for the vma after prev, which is new, whereas we actually intended to discover next! So we end up with: start end | | |----|-----|------| |prev| vma | next | |----|-----|------| And we have successfully bypassed all of the checks madvise_walk_vmas() has to ensure early exit should we end up moving out of range. We loop around, and hit: /* Here vma->vm_start <= start < (end|vma->vm_end) */ tmp = vma->vm_end; Oh dear. Now we have: tmp start end | | |----|-----|------| |prev| vma | next | |----|-----|------| We then invoke: /* Here vma->vm_start <= start < tmp <= (end|vma->vm_end). */ error = visit(vma, &prev, start, tmp, arg); Where start == tmp. That is, a zero range. This is not good. We invoke visit() which is madvise_vma_behavior() which does not check the range (for good reason, it assumes all checks have been done before it was called), which in turn finally calls madvise_update_vma(). The madvise_update_vma() function calls vma_modify_flags_name() in turn, which ultimately invokes vma_modify() with... start == end. vma_modify() calls vma_merge_existing_range() and finally we hit: VM_WARN_ON_VMG(start >= end, vmg); Which triggers, as start == end.

[PATCH AUTOSEL 6.10 01/27] wifi: nl80211: disallow setting special AP channel widths

by Sasha Levin

From: Johannes Berg <johannes.berg(a)intel.com> [ Upstream commit 23daf1b4c91db9b26f8425cc7039cf96d22ccbfe ] Setting the AP channel width is meant for use with the normal 20/40/...

[REGRESSION] Chrome and VSCode breakage with the commit b9b588f22a0c

by Takashi Iwai

Hi, we received a bug report showing the regression on 6.13.1 kernel against 6.13.0. The symptom is that Chrome and VSCode stopped working with Gnome Scaling, as reported on openSUSE Tumbleweed bug tracker https://bugzilla.suse.com/show_bug.cgi?id=1236943 Quoting from there: """ I use the latest TW on Gnome with a 4K display and 150% scaling. Everything has been working fine, but recently both Chrome and VSCode (installed from official non-openSUSE channels) stopped working with Scaling. .... I am using VSCode with: `--enable-features=UseOzonePlatform --enable-features=WaylandWindowDecorations --ozone-platform-hint=auto` and for Chrome, I select `Preferred Ozone platform` == `Wayland`. """ Surprisingly, the bisection pointed to the backport of the commit b9b588f22a0c049a14885399e27625635ae6ef91 ("libfs: Use d_children list to iterate simple_offset directories"). Indeed, the revert of this patch on the latest 6.13.4 was confirmed to fix the issue. Also, the reporter verified that the latest 6.14-rc release is still affected, too. For now I have no concrete idea how the patch could break the behavior of a graphical application like the above. Let us know if you need something for debugging. (Or at easiest, join to the bugzilla entry and ask there; or open another bug report at whatever you like.) BTW, I'll be traveling tomorrow, so my reply will be delayed. thanks, Takashi #regzbot introduced: b9b588f22a0c049a14885399e27625635ae6ef91 #regzbot monitor: https://bugzilla.suse.com/show_bug.cgi?id=1236943

+ mm-abort-vma_modify-on-merge-out-of-memory-failure.patch added to mm-hotfixes-unstable branch

The patch titled Subject: mm: abort vma_modify() on merge out of memory failure has been added to the -mm mm-hotfixes-unstable branch. Its filename is mm-abort-vma_modify-on-merge-out-of-memory-failure.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patche… This patch will later appear in the mm-hotfixes-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm 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 via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Lorenzo Stoakes <lorenzo.stoakes(a)oracle.com> Subject: mm: abort vma_modify() on merge out of memory failure Date: Sat, 22 Feb 2025 16:19:52 +0000 The remainder of vma_modify() relies upon the vmg state remaining pristine after a merge attempt. Usually this is the case, however in the one edge case scenario of a merge attempt failing not due to the specified range being unmergeable, but rather due to an out of memory error arising when attempting to commit the merge, this assumption becomes untrue. This results in vmg->start, end being modified, and thus the proceeding attempts to split the VMA will be done with invalid start/end values. Thankfully, it is likely practically impossible for us to hit this in reality, as it would require a maple tree node pre-allocation failure that would likely never happen due to it being 'too small to fail', i.e. the kernel would simply keep retrying reclaim until it succeeded. However, this scenario remains theoretically possible, and what we are doing here is wrong so we must correct it. The safest option is, when this scenario occurs, to simply give up the operation. If we cannot allocate memory to merge, then we cannot allocate memory to split either (perhaps moreso!). Any scenario where this would be happening would be under very extreme (likely fatal) memory pressure, so it's best we give up early. So there is no doubt it is appropriate to simply bail out in this scenario. However, in general we must if at all possible never assume VMG state is stable after a merge attempt, since merge operations update VMG fields. As a result, additionally also make this clear by storing start, end in local variables. The issue was reported originally by syzkaller, and by Brad Spengler (via an off-list discussion), and in both instances it manifested as a triggering of the assert: VM_WARN_ON_VMG(start >= end, vmg); In vma_merge_existing_range(). It seems at least one scenario in which this is occurring is one in which the merge being attempted is due to an madvise() across multiple VMAs which looks like this: start end |<------>| |----------|------| | vma | next | |----------|------| When madvise_walk_vmas() is invoked, we first find vma in the above (determining prev to be equal to vma as we are offset into vma), and then enter the loop. We determine the end of vma that forms part of the range we are madvise()'ing by setting 'tmp' to this value: /* Here vma->vm_start <= start < (end|vma->vm_end) */ tmp = vma->vm_end; We then invoke the madvise() operation via visit(), letting prev get updated to point to vma as part of the operation: /* Here vma->vm_start <= start < tmp <= (end|vma->vm_end). */ error = visit(vma, &prev, start, tmp, arg); Where the visit() function pointer in this instance is madvise_vma_behavior(). As observed in syzkaller reports, it is ultimately madvise_update_vma() that is invoked, calling vma_modify_flags_name() and vma_modify() in turn. Then, in vma_modify(), we attempt the merge: merged = vma_merge_existing_range(vmg); if (merged) return merged; We invoke this with vmg->start, end set to start, tmp as such: start tmp |<--->| |----------|------| | vma | next | |----------|------| We find ourselves in the merge right scenario, but the one in which we cannot remove the middle (we are offset into vma). Here we have a special case where vmg->start, end get set to perhaps unintuitive values - we intended to shrink the middle VMA and expand the next. This means vmg->start, end are set to... vma->vm_start, start. Now the commit_merge() fails, and vmg->start, end are left like this. This means we return to the rest of vma_modify() with vmg->start, end (here denoted as start', end') set as: start' end' |<-->| |----------|------| | vma | next | |----------|------| So we now erroneously try to split accordingly. This is where the unfortunate stuff begins. We start with: /* Split any preceding portion of the VMA. */ if (vma->vm_start < vmg->start) { ... } This doesn't trigger as we are no longer offset into vma at the start. But then we invoke: /* Split any trailing portion of the VMA. */ if (vma->vm_end > vmg->end) { ... } Which does get invoked. This leaves us with: start' end' |<-->| |----|-----|------| | vma| new | next | |----|-----|------| We then return ultimately to madvise_walk_vmas(). Here 'new' is unknown, and putting back the values known in this function we are faced with: start tmp end | | | |----|-----|------| | vma| new | next | |----|-----|------| prev Then: start = tmp; So: start end | | |----|-----|------| | vma| new | next | |----|-----|------| prev The following code does not cause anything to happen: if (prev && start < prev->vm_end) start = prev->vm_end; if (start >= end) break; And then we invoke: if (prev) vma = find_vma(mm, prev->vm_end); Which is where a problem occurs - we don't know about 'new' so we essentially look for the vma after prev, which is new, whereas we actually intended to discover next! So we end up with: start end | | |----|-----|------| |prev| vma | next | |----|-----|------| And we have successfully bypassed all of the checks madvise_walk_vmas() has to ensure early exit should we end up moving out of range. We loop around, and hit: /* Here vma->vm_start <= start < (end|vma->vm_end) */ tmp = vma->vm_end; Oh dear. Now we have: tmp start end | | |----|-----|------| |prev| vma | next | |----|-----|------| We then invoke: /* Here vma->vm_start <= start < tmp <= (end|vma->vm_end). */ error = visit(vma, &prev, start, tmp, arg); Where start == tmp. That is, a zero range. This is not good. We invoke visit() which is madvise_vma_behavior() which does not check the range (for good reason, it assumes all checks have been done before it was called), which in turn finally calls madvise_update_vma(). The madvise_update_vma() function calls vma_modify_flags_name() in turn, which ultimately invokes vma_modify() with... start == end. vma_modify() calls vma_merge_existing_range() and finally we hit: VM_WARN_ON_VMG(start >= end, vmg); Which triggers, as start == end. While it might be useful to add some CONFIG_DEBUG_VM asserts in these instances to catch this kind of error, since we have just eliminated any possibility of that happening, we will add such asserts separately as to reduce churn and aid backporting.

[PATCH v2 0/5] arm64: dts: rockchip: pinmux fixes and support for 2 adapters for Theobroma boards

This is based on top of https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git/lo… 6ee0b9ad3995 ("arm64: dts: rockchip: Add rng node to RK3588") as it depends on the (merged) series from https://lore.kernel.org/all/20250211-pre-ict-jaguar-v6-0-4484b0f88cfc@cherr… Patches for Haikou Video Demo adapter for PX30 Ringneck and RK3399 Puma (patches 4 and 5) also depend on the following patch series: https://lore.kernel.org/linux-devicetree/20250220-pca976x-reset-driver-v1-0… This fixes incorrect pinmux on UART0 and UART5 for PX30 Ringneck on Haikou. This adds support for the HAIKOU-LVDS-9904379 adapter for PX30 Ringneck fitted on a Haikou carrierboard. Additionally, this adds support for Haikou Video Demo adapter on PX30 Ringneck and RK3399 Puma fitted on a Haikou carrierboard. Notably missing from the overlay is the OV5675 camera module which expects 19.2MHz which we cannot exactly feed right now. Modifications to the OV5675 drivers will be made so it's more flexible and then support for the camera module will be added. This adapter has a 720x1280 DSI display with a GT911 touchscreen, a GPIO-controllable LED and an I2C GPIO expander. Support for this adapter on RK3588 Tiger is being added in a separate patch series[1]. Note that the DSI panel currently is glitchy on both PX30 Ringneck and RK3399 Puma but this is being tackled in another series[2]. Since this will not be fixed through DT properties for the panel, adding the DT nodes for the DSI panel even if not perfect right now seems acceptable to me.

[PATCH 6.6] x86/cpu/kvm: SRSO: Fix possible missing IBPB on VM-Exit

by Patrick Bellasi

commit 318e8c339c9a0891c389298bb328ed0762a9935e upstream. In [1] the meaning of the synthetic IBPB flags has been redefined for a better separation of concerns: - ENTRY_IBPB -- issue IBPB on entry only - IBPB_ON_VMEXIT -- issue IBPB on VM-Exit only and the Retbleed mitigations have been updated to match this new semantics. Commit [2] was merged shortly before [1], and their interaction was not handled properly. This resulted in IBPB not being triggered on VM-Exit in all SRSO mitigation configs requesting an IBPB there. Specifically, an IBPB on VM-Exit is triggered only when X86_FEATURE_IBPB_ON_VMEXIT is set. However: - X86_FEATURE_IBPB_ON_VMEXIT is not set for "spec_rstack_overflow=ibpb", because before [1] having X86_FEATURE_ENTRY_IBPB was enough. Hence, an IBPB is triggered on entry but the expected IBPB on VM-exit is not. - X86_FEATURE_IBPB_ON_VMEXIT is not set also when "spec_rstack_overflow=ibpb-vmexit" if X86_FEATURE_ENTRY_IBPB is already set. That's because before [1] this was effectively redundant. Hence, e.g. a "retbleed=ibpb spec_rstack_overflow=bpb-vmexit" config mistakenly reports the machine still vulnerable to SRSO, despite an IBPB being triggered both on entry and VM-Exit, because of the Retbleed selected mitigation config. - UNTRAIN_RET_VM won't still actually do anything unless CONFIG_MITIGATION_IBPB_ENTRY is set. For "spec_rstack_overflow=ibpb", enable IBPB on both entry and VM-Exit and clear X86_FEATURE_RSB_VMEXIT which is made superfluous by X86_FEATURE_IBPB_ON_VMEXIT. This effectively makes this mitigation option similar to the one for 'retbleed=ibpb', thus re-order the code for the RETBLEED_MITIGATION_IBPB option to be less confusing by having all features enabling before the disabling of the not needed ones. For "spec_rstack_overflow=ibpb-vmexit", guard this mitigation setting with CONFIG_MITIGATION_IBPB_ENTRY to ensure UNTRAIN_RET_VM sequence is effectively compiled in. Drop instead the CONFIG_MITIGATION_SRSO guard, since none of the SRSO compile cruft is required in this configuration.

[PATCH 5.10] x86/cpu/kvm: SRSO: Fix possible missing IBPB on VM-Exit

by Patrick Bellasi

commit 318e8c339c9a0891c389298bb328ed0762a9935e upstream. In [1] the meaning of the synthetic IBPB flags has been redefined for a better separation of concerns: - ENTRY_IBPB -- issue IBPB on entry only - IBPB_ON_VMEXIT -- issue IBPB on VM-Exit only and the Retbleed mitigations have been updated to match this new semantics. Commit [2] was merged shortly before [1], and their interaction was not handled properly. This resulted in IBPB not being triggered on VM-Exit in all SRSO mitigation configs requesting an IBPB there. Specifically, an IBPB on VM-Exit is triggered only when X86_FEATURE_IBPB_ON_VMEXIT is set. However: - X86_FEATURE_IBPB_ON_VMEXIT is not set for "spec_rstack_overflow=ibpb", because before [1] having X86_FEATURE_ENTRY_IBPB was enough. Hence, an IBPB is triggered on entry but the expected IBPB on VM-exit is not. - X86_FEATURE_IBPB_ON_VMEXIT is not set also when "spec_rstack_overflow=ibpb-vmexit" if X86_FEATURE_ENTRY_IBPB is already set. That's because before [1] this was effectively redundant. Hence, e.g. a "retbleed=ibpb spec_rstack_overflow=bpb-vmexit" config mistakenly reports the machine still vulnerable to SRSO, despite an IBPB being triggered both on entry and VM-Exit, because of the Retbleed selected mitigation config. - UNTRAIN_RET_VM won't still actually do anything unless CONFIG_MITIGATION_IBPB_ENTRY is set. For "spec_rstack_overflow=ibpb", enable IBPB on both entry and VM-Exit and clear X86_FEATURE_RSB_VMEXIT which is made superfluous by X86_FEATURE_IBPB_ON_VMEXIT. This effectively makes this mitigation option similar to the one for 'retbleed=ibpb', thus re-order the code for the RETBLEED_MITIGATION_IBPB option to be less confusing by having all features enabling before the disabling of the not needed ones. For "spec_rstack_overflow=ibpb-vmexit", guard this mitigation setting with CONFIG_MITIGATION_IBPB_ENTRY to ensure UNTRAIN_RET_VM sequence is effectively compiled in. Drop instead the CONFIG_MITIGATION_SRSO guard, since none of the SRSO compile cruft is required in this configuration. Also, check only that the required microcode is present to effectively enabled the IBPB on VM-Exit. Finally, update the KConfig description for CONFIG_MITIGATION_IBPB_ENTRY to list also all SRSO config settings enabled by this guard.

FTBFS: Rust firmware abstractions in current stable (6.13.4) on arm64 with rustc 1.85.0

Hi! The Rust firmware abstractions FTBFS on arm64 and current stable (6.13.4) when compiled with rustc 1.85.0: ``` RUSTC L rust/kernel.o error[E0308]: mismatched types --> rust/kernel/firmware.rs:20:14 | 20 | Self(bindings::request_firmware) | ---- ^^^^^^^^^^^^^^^^^^^^^^^^^^ expected fn pointer, found fn item | | | arguments to this function are incorrect | = note: expected fn pointer `unsafe extern "C" fn(_, *const i8, _) -> _` found fn item `unsafe extern "C" fn(_, *const u8, _) -> _ {request_firmware}` note: tuple struct defined here --> rust/kernel/firmware.rs:14:8 | 14 | struct FwFunc( | ^^^^^^ error[E0308]: mismatched types --> rust/kernel/firmware.rs:24:14 | 24 | Self(bindings::firmware_request_nowarn) | ---- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ expected fn pointer, found fn item | | | arguments to this function are incorrect | = note: expected fn pointer `unsafe extern "C" fn(_, *const i8, _) -> _` found fn item `unsafe extern "C" fn(_, *const u8, _) -> _ {firmware_request_nowarn}` note: tuple struct defined here --> rust/kernel/firmware.rs:14:8 | 14 | struct FwFunc( | ^^^^^^ error[E0308]: mismatched types --> rust/kernel/firmware.rs:64:45 | 64 | let ret = unsafe { func.0(pfw as _, name.as_char_ptr(), dev.as_raw()) }; | ------ ^^^^^^^^^^^^^^^^^^ expected `*const i8`, found `*const u8` | | | arguments to this function are incorrect | = note: expected raw pointer `*const i8` found raw pointer `*const u8` error: aborting due to 3 previous errors For more information about this error, try `rustc --explain E0308`. ``` This is because rustc 1.85 (now stable) switched core::ffi::c_char from i8 to u8 on arm64 and other platforms [1], and because current stable still uses rustc's core's instead of the custom ffi integer types like 6.14 will. Looking for other i8's in *.rs files tells me only the QR code panic screen should be affected in addition to the firmware abstractions, and that was already reported in [2]. A simple fix would be to switch i8 to u8 in `struct FwFunc`, but that breaks rustc <= 1.84 so I guess a more robust solution is needed. Cheers!

[PATCH] ARM: add KEEP() keyword to ARM_VECTORS

by Christian Eggers

Without this, the vectors are removed if LD_DEAD_CODE_DATA_ELIMINATION is enabled. At startup, the CPU (silently) hangs in the undefined instruction exception as soon as the first timer interrupt arrives. On my setup, the system also boots fine without the 2nd and 3rd KEEP() statements, so I cannot tell whether these are actually required.

[PATCH 0/2] A couple of build fixes for x86 when using GCC 15

by Nathan Chancellor

Hi all, GCC 15 changed the default C standard version from gnu17 to gnu23, which reveals a few places in the kernel where a C standard version was not set, resulting in build failures because bool, true, and false are reserved keywords in C23 [1][2]. Update these places to use the same C standard version as the rest of the kernel, gnu11.

Some of the used metric sources require locks which might need to sleep. This sleep is incompatible with the RCU list iterator used for the recorded neighbors. The initial approach to work around of this problem was to queue another work item per neighbor and then run this in a new context. Even when this solved the RCU vs might_sleep() conflict, it has a major problems: Nothing was stopping the work item in case it is not needed anymore - for example because one of the related interfaces was removed or the batman-adv module was unloaded - resulting in potential invalid memory accesses. Directly canceling the metric worker also has various problems: * cancel_work_sync for a to-be-deactivated interface is called with rtnl_lock held. But the code in the ELP metric worker also tries to use rtnl_lock() - which will never return in this case. This also means that cancel_work_sync would never return because it is waiting for the worker to finish. * iterating over the neighbor list for the to-be-deactivated interface is currently done using the RCU specific methods. Which means that it is possible to miss items when iterating over it without the associated spinlock - a behaviour which is acceptable for a periodic metric check but not for a cleanup routine (which must "stop" all still running workers) The better approch is to get rid of the per interface neighbor metric worker and handle everything in the interface worker. The original problems are solved by: * creating a list of neighbors which require new metric information inside the RCU protected context, gathering the metric according to the new list outside the RCU protected context * only use rcu_trylock inside metric gathering code to avoid a deadlock when the cancel_delayed_work_sync is called in the interface removal code (which is called with the rtnl_lock held) Cc: stable(a)vger.kernel.org Fixes: c833484e5f38 ("batman-adv: ELP - compute the metric based on the estimated throughput") Signed-off-by: Sven Eckelmann <sven(a)narfation.org> Signed-off-by: Simon Wunderlich <sw(a)simonwunderlich.de> diff --git a/net/batman-adv/bat_v.c b/net/batman-adv/bat_v.c index ac11f1f08db0..d35479c465e2 100644 --- a/net/batman-adv/bat_v.c +++ b/net/batman-adv/bat_v.c @@ -113,8 +113,6 @@ static void batadv_v_hardif_neigh_init(struct batadv_hardif_neigh_node *hardif_neigh) { ewma_throughput_init(&hardif_neigh->bat_v.throughput); - INIT_WORK(&hardif_neigh->bat_v.metric_work, - batadv_v_elp_throughput_metric_update); } /** diff --git a/net/batman-adv/bat_v_elp.c b/net/batman-adv/bat_v_elp.c index 65e52de52bcd..b065578b4436 100644 --- a/net/batman-adv/bat_v_elp.c +++ b/net/batman-adv/bat_v_elp.c @@ -18,6 +18,7 @@ #include <linux/if_ether.h> #include <linux/jiffies.h> #include <linux/kref.h> +#include <linux/list.h> #include <linux/minmax.h> #include <linux/netdevice.h> #include <linux/nl80211.h> @@ -26,6 +27,7 @@ #include <linux/rcupdate.h> #include <linux/rtnetlink.h> #include <linux/skbuff.h> +#include <linux/slab.h> #include <linux/stddef.h> #include <linux/string.h> #include <linux/types.h> @@ -41,6 +43,18 @@ #include "routing.h" #include "send.h" +/** + * struct batadv_v_metric_queue_entry - list of hardif neighbors which require + * and metric update + */ +struct batadv_v_metric_queue_entry { + /** @hardif_neigh: hardif neighbor scheduled for metric update */ + struct batadv_hardif_neigh_node *hardif_neigh; + + /** @list: list node for metric_queue */ + struct list_head list; +}; + /** * batadv_v_elp_start_timer() - restart timer for ELP periodic work * @hard_iface: the interface for which the timer has to be reset @@ -137,10 +151,17 @@ static bool batadv_v_elp_get_throughput(struct batadv_hardif_neigh_node *neigh, goto default_throughput; } + /* only use rtnl_trylock because the elp worker will be cancelled while + * the rntl_lock is held. the cancel_delayed_work_sync() would otherwise + * wait forever when the elp work_item was started and it is then also + * trying to rtnl_lock + */ + if (!rtnl_trylock()) + return false; + /* if not a wifi interface, check if this device provides data via * ethtool (e.g. an Ethernet adapter) */ - rtnl_lock(); ret = __ethtool_get_link_ksettings(hard_iface->net_dev, &link_settings); rtnl_unlock(); if (ret == 0) { @@ -175,31 +196,19 @@ static bool batadv_v_elp_get_throughput(struct batadv_hardif_neigh_node *neigh, /** * batadv_v_elp_throughput_metric_update() - worker updating the throughput * metric of a single hop neighbour - * @work: the work queue item + * @neigh: the neighbour to probe */ -void batadv_v_elp_throughput_metric_update(struct work_struct *work) +static void +batadv_v_elp_throughput_metric_update(struct batadv_hardif_neigh_node *neigh) { - struct batadv_hardif_neigh_node_bat_v *neigh_bat_v; - struct batadv_hardif_neigh_node *neigh; u32 throughput; bool valid; - neigh_bat_v = container_of(work, struct batadv_hardif_neigh_node_bat_v, - metric_work); - neigh = container_of(neigh_bat_v, struct batadv_hardif_neigh_node, - bat_v); - valid = batadv_v_elp_get_throughput(neigh, &throughput); if (!valid) - goto put_neigh; + return; ewma_throughput_add(&neigh->bat_v.throughput, throughput); - -put_neigh: - /* decrement refcounter to balance increment performed before scheduling - * this task - */ - batadv_hardif_neigh_put(neigh); } /** @@ -273,14 +282,16 @@ batadv_v_elp_wifi_neigh_probe(struct batadv_hardif_neigh_node *neigh) */ static void batadv_v_elp_periodic_work(struct work_struct *work) { + struct batadv_v_metric_queue_entry *metric_entry; + struct batadv_v_metric_queue_entry *metric_safe; struct batadv_hardif_neigh_node *hardif_neigh; struct batadv_hard_iface *hard_iface; struct batadv_hard_iface_bat_v *bat_v; struct batadv_elp_packet *elp_packet; + struct list_head metric_queue; struct batadv_priv *bat_priv; struct sk_buff *skb; u32 elp_interval; - bool ret; bat_v = container_of(work, struct batadv_hard_iface_bat_v, elp_wq.work); hard_iface = container_of(bat_v, struct batadv_hard_iface, bat_v); @@ -316,6 +327,8 @@ static void batadv_v_elp_periodic_work(struct work_struct *work) atomic_inc(&hard_iface->bat_v.elp_seqno); + INIT_LIST_HEAD(&metric_queue); + /* The throughput metric is updated on each sent packet.

[to-be-updated] panic-call-panic-handlers-before-panic_other_cpus_shutdown.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: panic: call panic handlers before panic_other_cpus_shutdown() has been removed from the -mm tree.

[PATCH RESEND net-next] net: stmmac: dwmac-rk: Provide FIFO sizes for DWMAC 1000

by Chen-Yu Tsai

From: Chen-Yu Tsai <wens(a)csie.org> The DWMAC 1000 DMA capabilities register does not provide actual FIFO sizes, nor does the driver really care. If they are not provided via some other means, the driver will work fine, only disallowing changing the MTU setting. The recent commit 8865d22656b4 ("net: stmmac: Specify hardware capability value when FIFO size isn't specified") changed this by requiring the FIFO sizes to be provided, breaking devices that were working just fine. Provide the FIFO sizes through the driver's platform data, to not only fix the breakage, but also enable MTU changes. The FIFO sizes are confirmed to be the same across RK3288, RK3328, RK3399 and PX30, based on their respective manuals. It is likely that Rockchip synthesized their DWMAC 1000 with the same parameters on all their chips that have it. Fixes: eaf4fac47807 ("net: stmmac: Do not accept invalid MTU values") Fixes: 8865d22656b4 ("net: stmmac: Specify hardware capability value when FIFO size isn't specified") Cc: <stable(a)vger.kernel.org> Signed-off-by: Chen-Yu Tsai <wens(a)csie.org> --- (Resending to net-next instead of netdev.)

[PATCH] x86/tsc: Always save/restore TSC sched_clock on suspend/resume

by Guilherme G. Piccoli

TSC could be reset in deep ACPI sleep states, even with invariant TSC. That's the reason we have sched_clock() save/restore functions, to deal with this situation. But happens that such functions are guarded with a check for the stability of sched_clock - if not considered stable, the save/restore routines aren't executed. On top of that, we have a clear comment on native_sched_clock() saying that *even* with TSC unstable, we continue using TSC for sched_clock due to its speed. In other words, if we have a situation of TSC getting detected as unstable, it marks the sched_clock as unstable as well, so subsequent S3 sleep cycles could bring bogus sched_clock values due to the lack of the save/restore mechanism, causing warnings like this: [22.954918] ------------[ cut here ]------------ [22.954923] Delta way too big! 18446743750843854390 ts=18446744072977390405 before=322133536015 after=322133536015 write stamp=18446744072977390405 [22.954923] If you just came from a suspend/resume, [22.954923] please switch to the trace global clock: [22.954923] echo global > /sys/kernel/tracing/trace_clock [22.954923] or add trace_clock=global to the kernel command line [22.954937] WARNING: CPU: 2 PID: 5728 at kernel/trace/ring_buffer.c:2890 rb_add_timestamp+0x193/0x1c0 Notice that the above was reproduced even with "trace_clock=global". The fix for that is to _always_ save/restore the sched_clock on suspend cycle _if TSC is used_ as sched_clock - only if we fallback to jiffies the sched_clock_stable() check becomes relevant to save/restore the sched_clock.

Some of the used metric sources require locks which might need to sleep. This sleep is incompatible with the RCU list iterator used for the recorded neighbors. The initial approach to work around of this problem was to queue another work item per neighbor and then run this in a new context. Even when this solved the RCU vs might_sleep() conflict, it has a major problems: Nothing was stopping the work item in case it is not needed anymore - for example because one of the related interfaces was removed or the batman-adv module was unloaded - resulting in potential invalid memory accesses. Directly canceling the metric worker also has various problems: * cancel_work_sync for a to-be-deactivated interface is called with rtnl_lock held. But the code in the ELP metric worker also tries to use rtnl_lock() - which will never return in this case. This also means that cancel_work_sync would never return because it is waiting for the worker to finish. * iterating over the neighbor list for the to-be-deactivated interface is currently done using the RCU specific methods. Which means that it is possible to miss items when iterating over it without the associated spinlock - a behaviour which is acceptable for a periodic metric check but not for a cleanup routine (which must "stop" all still running workers) The better approch is to get rid of the per interface neighbor metric worker and handle everything in the interface worker. The original problems are solved by: * creating a list of neighbors which require new metric information inside the RCU protected context, gathering the metric according to the new list outside the RCU protected context * only use rcu_trylock inside metric gathering code to avoid a deadlock when the cancel_delayed_work_sync is called in the interface removal code (which is called with the rtnl_lock held) Cc: stable(a)vger.kernel.org Fixes: c833484e5f38 ("batman-adv: ELP - compute the metric based on the estimated throughput") Signed-off-by: Sven Eckelmann <sven(a)narfation.org> Signed-off-by: Simon Wunderlich <sw(a)simonwunderlich.de> diff --git a/net/batman-adv/bat_v.c b/net/batman-adv/bat_v.c index ac11f1f08db0..d35479c465e2 100644 --- a/net/batman-adv/bat_v.c +++ b/net/batman-adv/bat_v.c @@ -113,8 +113,6 @@ static void batadv_v_hardif_neigh_init(struct batadv_hardif_neigh_node *hardif_neigh) { ewma_throughput_init(&hardif_neigh->bat_v.throughput); - INIT_WORK(&hardif_neigh->bat_v.metric_work, - batadv_v_elp_throughput_metric_update); } /** diff --git a/net/batman-adv/bat_v_elp.c b/net/batman-adv/bat_v_elp.c index 65e52de52bcd..b065578b4436 100644 --- a/net/batman-adv/bat_v_elp.c +++ b/net/batman-adv/bat_v_elp.c @@ -18,6 +18,7 @@ #include <linux/if_ether.h> #include <linux/jiffies.h> #include <linux/kref.h> +#include <linux/list.h> #include <linux/minmax.h> #include <linux/netdevice.h> #include <linux/nl80211.h> @@ -26,6 +27,7 @@ #include <linux/rcupdate.h> #include <linux/rtnetlink.h> #include <linux/skbuff.h> +#include <linux/slab.h> #include <linux/stddef.h> #include <linux/string.h> #include <linux/types.h> @@ -41,6 +43,18 @@ #include "routing.h" #include "send.h" +/** + * struct batadv_v_metric_queue_entry - list of hardif neighbors which require + * and metric update + */ +struct batadv_v_metric_queue_entry { + /** @hardif_neigh: hardif neighbor scheduled for metric update */ + struct batadv_hardif_neigh_node *hardif_neigh; + + /** @list: list node for metric_queue */ + struct list_head list; +}; + /** * batadv_v_elp_start_timer() - restart timer for ELP periodic work * @hard_iface: the interface for which the timer has to be reset @@ -137,10 +151,17 @@ static bool batadv_v_elp_get_throughput(struct batadv_hardif_neigh_node *neigh, goto default_throughput; } + /* only use rtnl_trylock because the elp worker will be cancelled while + * the rntl_lock is held. the cancel_delayed_work_sync() would otherwise + * wait forever when the elp work_item was started and it is then also + * trying to rtnl_lock + */ + if (!rtnl_trylock()) + return false; + /* if not a wifi interface, check if this device provides data via * ethtool (e.g. an Ethernet adapter) */ - rtnl_lock(); ret = __ethtool_get_link_ksettings(hard_iface->net_dev, &link_settings); rtnl_unlock(); if (ret == 0) { @@ -175,31 +196,19 @@ static bool batadv_v_elp_get_throughput(struct batadv_hardif_neigh_node *neigh, /** * batadv_v_elp_throughput_metric_update() - worker updating the throughput * metric of a single hop neighbour - * @work: the work queue item + * @neigh: the neighbour to probe */ -void batadv_v_elp_throughput_metric_update(struct work_struct *work) +static void +batadv_v_elp_throughput_metric_update(struct batadv_hardif_neigh_node *neigh) { - struct batadv_hardif_neigh_node_bat_v *neigh_bat_v; - struct batadv_hardif_neigh_node *neigh; u32 throughput; bool valid; - neigh_bat_v = container_of(work, struct batadv_hardif_neigh_node_bat_v, - metric_work); - neigh = container_of(neigh_bat_v, struct batadv_hardif_neigh_node, - bat_v); - valid = batadv_v_elp_get_throughput(neigh, &throughput); if (!valid) - goto put_neigh; + return; ewma_throughput_add(&neigh->bat_v.throughput, throughput); - -put_neigh: - /* decrement refcounter to balance increment performed before scheduling - * this task - */ - batadv_hardif_neigh_put(neigh); } /** @@ -273,14 +282,16 @@ batadv_v_elp_wifi_neigh_probe(struct batadv_hardif_neigh_node *neigh) */ static void batadv_v_elp_periodic_work(struct work_struct *work) { + struct batadv_v_metric_queue_entry *metric_entry; + struct batadv_v_metric_queue_entry *metric_safe; struct batadv_hardif_neigh_node *hardif_neigh; struct batadv_hard_iface *hard_iface; struct batadv_hard_iface_bat_v *bat_v; struct batadv_elp_packet *elp_packet; + struct list_head metric_queue; struct batadv_priv *bat_priv; struct sk_buff *skb; u32 elp_interval; - bool ret; bat_v = container_of(work, struct batadv_hard_iface_bat_v, elp_wq.work); hard_iface = container_of(bat_v, struct batadv_hard_iface, bat_v); @@ -316,6 +327,8 @@ static void batadv_v_elp_periodic_work(struct work_struct *work) atomic_inc(&hard_iface->bat_v.elp_seqno); + INIT_LIST_HEAD(&metric_queue); + /* The throughput metric is updated on each sent packet.

[PATCH v3 1/3] drm/xe/userptr: restore invalidation list on error

by Matthew Auld

On error restore anything still on the pin_list back to the invalidation list on error. For the actual pin, so long as the vma is tracked on either list it should get picked up on the next pin, however it looks possible for the vma to get nuked but still be present on this per vm pin_list leading to corruption. An alternative might be then to instead just remove the link when destroying the vma. v2: - Also add some asserts. - Keep the overzealous locking so that we are consistent with the docs; updating the docs and related bits will be done as a follow up.

[for-linus][PATCH 6/7] ftrace: Correct preemption accounting for function tracing.

by Steven Rostedt

From: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de> The function tracer should record the preemption level at the point when the function is invoked. If the tracing subsystem decrement the preemption counter it needs to correct this before feeding the data into the trace buffer. This was broken in the commit cited below while shifting the preempt-disabled section. Use tracing_gen_ctx_dec() which properly subtracts one from the preemption counter on a preemptible kernel.

[for-linus][PATCH 4/7] fprobe: Fix accounting of when to unregister from function graph

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> When adding a new fprobe, it will update the function hash to the functions the fprobe is attached to and register with function graph to have it call the registered functions. The fprobe_graph_active variable keeps track of the number of fprobes that are using function graph. If two fprobes attach to the same function, it increments the fprobe_graph_active for each of them. But when they are removed, the first fprobe to be removed will see that the function it is attached to is also used by another fprobe and it will not remove that function from function_graph. The logic will skip decrementing the fprobe_graph_active variable. This causes the fprobe_graph_active variable to not go to zero when all fprobes are removed, and in doing so it does not unregister from function graph. As the fgraph ops hash will now be empty, and an empty filter hash means all functions are enabled, this triggers function graph to add a callback to the fprobe infrastructure for every function! # echo "f:myevent1 kernel_clone" >> /sys/kernel/tracing/dynamic_events # echo "f:myevent2 kernel_clone%return" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kernel_clone (1) tramp: 0xffffffffc0024000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 # > /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions trace_initcall_start_cb (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 run_init_process (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 try_to_run_init_process (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 x86_pmu_show_pmu_cap (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 cleanup_rapl_pmus (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 uncore_free_pcibus_map (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 uncore_types_exit (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 uncore_pci_exit.part.0 (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 kvm_shutdown (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 vmx_dump_msrs (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 [..] # cat /sys/kernel/tracing/enabled_functions | wc -l 54702 If a fprobe is being removed and all its functions are also traced by other fprobes, still decrement the fprobe_graph_active counter.

[for-linus][PATCH 3/7] fprobe: Always unregister fgraph function from ops

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> When the last fprobe is removed, it calls unregister_ftrace_graph() to remove the graph_ops from function graph. The issue is when it does so, it calls return before removing the function from its graph ops via ftrace_set_filter_ips(). This leaves the last function lingering in the fprobe's fgraph ops and if a probe is added it also enables that last function (even though the callback will just drop it, it does add unneeded overhead to make that call). # echo "f:myevent1 kernel_clone" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kernel_clone (1) tramp: 0xffffffffc02f3000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 # echo "f:myevent2 schedule_timeout" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kernel_clone (1) tramp: 0xffffffffc02f3000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 schedule_timeout (1) tramp: 0xffffffffc02f3000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 # > /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions # echo "f:myevent3 kmem_cache_free" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kmem_cache_free (1) tramp: 0xffffffffc0219000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 schedule_timeout (1) tramp: 0xffffffffc0219000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 The above enabled a fprobe on kernel_clone, and then on schedule_timeout. The content of the enabled_functions shows the functions that have a callback attached to them. The fprobe attached to those functions properly. Then the fprobes were cleared, and enabled_functions was empty after that. But after adding a fprobe on kmem_cache_free, the enabled_functions shows that the schedule_timeout was attached again. This is because it was still left in the fprobe ops that is used to tell function graph what functions it wants callbacks from.

[for-linus][PATCH 1/7] ftrace: Fix accounting of adding subops to a manager ops

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> Function graph uses a subops and manager ops mechanism to attach to ftrace. The manager ops connects to ftrace and the functions it connects to is defined by a list of subops that it manages. The function hash that defines what the above ops attaches to limits the functions to attach if the hash has any content. If the hash is empty, it means to trace all functions. The creation of the manager ops hash is done by iterating over all the subops hashes. If any of the subops hashes is empty, it means that the manager ops hash must trace all functions as well. The issue is in the creation of the manager ops. When a second subops is attached, a new hash is created by starting it as NULL and adding the subops one at a time. But the NULL ops is mistaken as an empty hash, and once an empty hash is found, it stops the loop of subops and just enables all functions. # echo "f:myevent1 kernel_clone" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kernel_clone (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 # echo "f:myevent2 schedule_timeout" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions trace_initcall_start_cb (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 run_init_process (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 try_to_run_init_process (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 x86_pmu_show_pmu_cap (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 cleanup_rapl_pmus (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 uncore_free_pcibus_map (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 uncore_types_exit (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 uncore_pci_exit.part.0 (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 kvm_shutdown (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 vmx_dump_msrs (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 vmx_cleanup_l1d_flush (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 [..] Fix this by initializing the new hash to NULL and if the hash is NULL do not treat it as an empty hash but instead allocate by copying the content of the first sub ops.

[PATCH stable 5.10.y-6.12.y] arm64: mte: Do not allow PROT_MTE on MAP_HUGETLB user mappings

by Catalin Marinas

PROT_MTE (memory tagging extensions) is not supported on all user mmap() types for various reasons (memory attributes, backing storage, CoW handling). The arm64 arch_validate_flags() function checks whether the VM_MTE_ALLOWED flag has been set for a vma during mmap(), usually by arch_calc_vm_flag_bits(). Linux prior to 6.13 does not support PROT_MTE hugetlb mappings. This was added by commit 25c17c4b55de ("hugetlb: arm64: add mte support"). However, earlier kernels inadvertently set VM_MTE_ALLOWED on (MAP_ANONYMOUS | MAP_HUGETLB) mappings by only checking for MAP_ANONYMOUS. Explicitly check MAP_HUGETLB in arch_calc_vm_flag_bits() and avoid setting VM_MTE_ALLOWED for such mappings. Fixes: 9f3419315f3c ("arm64: mte: Add PROT_MTE support to mmap() and mprotect()") Cc: <stable(a)vger.kernel.org> # 5.10.x-6.12.x Reported-by: Naresh Kamboju <naresh.kamboju(a)linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas(a)arm.com> --- Hi Greg, This patch applies cleanly on top of the stable-rc/linux-6.12.y to 5.10.y LTS, so I'm only sending it once. It's not for 6.13 onwards since those kernels support hugetlbfs with MTE.

[PATCH] drm/radeon: Add error handlings for r420 cp errata initiation

by Wentao Liang

In r420_cp_errata_init(), the RESYNC information is stored even when the Scratch register is not correctly allocated. Change the return type of r420_cp_errata_init() from void to int to propagate errors to the caller. Add error checking after radeon_scratch_get() to ensure RESYNC information is stored to an allocated address. Log an error message and return the error code immediately when radeon_scratch_get() fails. Additionally, handle the return value of r420_cp_errata_init() in r420_startup() to log an appropriate error message and propagate the error if initialization fails.

[PATCH v2 1/3] drm/xe/userptr: restore invalidation list on error

by Matthew Auld

On error restore anything still on the pin_list back to the invalidation list on error. For the actual pin, so long as the vma is tracked on either list it should get picked up on the next pin, however it looks possible for the vma to get nuked but still be present on this per vm pin_list leading to corruption. An alternative might be then to instead just remove the link when destroying the vma.

[PATCH 0/5] arm64: dts: rockchip: pinmux fixes and support for 2 adapters for Theobroma boards

by Quentin Schulz

This is based on top of https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git/lo… 6ee0b9ad3995 ("arm64: dts: rockchip: Add rng node to RK3588") as it depends on the (merged) series from https://lore.kernel.org/all/20250211-pre-ict-jaguar-v6-0-4484b0f88cfc@cherr… Patches for Haikou Video Demo adapter for PX30 Ringneck and RK3399 Puma (patches 4 and 5) also depend on the following patch series: https://lore.kernel.org/linux-devicetree/20250220-pca976x-reset-driver-v1-0… This fixes incorrect pinmux on UART0 and UART5 for PX30 Ringneck on Haikou. This adds support for the HAIKOU-LVDS-9904379 adapter for PX30 Ringneck fitted on a Haikou carrierboard. Additionally, this adds support for Haikou Video Demo adapter on PX30 Ringneck and RK3399 Puma fitted on a Haikou carrierboard. Notably missing from the overlay is the OV5675 camera module which expects 19.2MHz which we cannot exactly feed right now. Modifications to the OV5675 drivers will be made so it's more flexible and then support for the camera module will be added. This adapter has a 720x1280 DSI display with a GT911 touchscreen, a GPIO-controllable LED and an I2C GPIO expander. Support for this adapter on RK3588 Tiger is being added in a separate patch series[1]. Note that the DSI panel currently is glitchy on both PX30 Ringneck and RK3399 Puma but this is being tackled in another series[2]. Since this will not be fixed through DT properties for the panel, adding the DT nodes for the DSI panel even if not perfect right now seems acceptable to me.

[PATCH 0/2] driver core: platform: avoid use-after-free on device name

by Théo Lebrun

The use-after-free bug appears when: - A platform device is created from OF, by of_device_add(); - The same device's name is changed afterwards using dev_set_name(), by its probe for example. Out of the 37 drivers that deal with platform devices and do a dev_set_name() call, only one might be affected. That driver is loongson-i2s-plat [0]. All other dev_set_name() calls are on children devices created on the spot. The issue was found on downstream kernels and we don't have what it takes to test loongson-i2s-plat. Note: loongson-i2s-plat maintainers are CCed. ⟩ # Finding potential trouble-makers: ⟩ git grep -l 'struct platform_device' | xargs grep -l dev_set_name The solution proposed is to add a flag to platform_device that tells if it is responsible for freeing its name. We can then duplicate the device name inside of_device_add() instead of copying the pointer.

[PATCH 1/1] iommu/vt-d: Fix suspicious RCU usage

by Lu Baolu

Commit <d74169ceb0d2> ("iommu/vt-d: Allocate DMAR fault interrupts locally") moved the call to enable_drhd_fault_handling() to a code path that does not hold any lock while traversing the drhd list.

[PATCH V5 2/4] x86/tdx: Route safe halt execution via tdx_safe_halt()

by Vishal Annapurve

Direct HLT instruction execution causes #VEs for TDX VMs which is routed to hypervisor via TDCALL. safe_halt() routines execute HLT in STI-shadow so IRQs need to remain disabled until the TDCALL to ensure that pending IRQs are correctly treated as wake events. So "sti;hlt" sequence needs to be replaced for TDX VMs with "TDCALL; *_irq_enable()" to keep interrupts disabled during TDCALL execution. Commit bfe6ed0c6727 ("x86/tdx: Add HLT support for TDX guests") prevented the idle routines from using "sti;hlt".

[PATCH v3 1/5] ftrace: Fix accounting of adding subops to a manager ops

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> Function graph uses a subops and manager ops mechanism to attach to ftrace. The manager ops connects to ftrace and the functions it connects to is defined by a list of subops that it manages. The function hash that defines what the above ops attaches to limits the functions to attach if the hash has any content. If the hash is empty, it means to trace all functions. The creation of the manager ops hash is done by iterating over all the subops hashes. If any of the subops hashes is empty, it means that the manager ops hash must trace all functions as well. The issue is in the creation of the manager ops. When a second subops is attached, a new hash is created by starting it as NULL and adding the subops one at a time. But the NULL ops is mistaken as an empty hash, and once an empty hash is found, it stops the loop of subops and just enables all functions. # echo "f:myevent1 kernel_clone" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kernel_clone (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 # echo "f:myevent2 schedule_timeout" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions trace_initcall_start_cb (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 run_init_process (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 try_to_run_init_process (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 x86_pmu_show_pmu_cap (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 cleanup_rapl_pmus (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 uncore_free_pcibus_map (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 uncore_types_exit (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 uncore_pci_exit.part.0 (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 kvm_shutdown (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 vmx_dump_msrs (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 vmx_cleanup_l1d_flush (1) tramp: 0xffffffffc0309000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 [..] Fix this by initializing the new hash to NULL and if the hash is NULL do not treat it as an empty hash but instead allocate by copying the content of the first sub ops.

[PATCH v2 1/2] asm-generic/vmlinux.lds: Move .data.rel.ro input into .rodata segment

by Ard Biesheuvel

From: Ard Biesheuvel <ardb(a)kernel.org> When using -fPIE codegen, the compiler will emit const global objects (which are useless unless statically initialized) into .data.rel.ro rather than .rodata if the object contains fields that carry absolute addresses of other code or data objects. This permits the linker to annotate such regions as requiring read-write access only at load time, but not at execution time (in user space). This distinction does not matter for the kernel, but it does imply that const data will end up in writable memory if the .data.rel.ro sections are not treated in a special way. So emit .data.rel.ro into the .rodata segment.

[PATCH] firmware: cs_dsp: test_control_parse: null-terminate test strings

by Thomas Weißschuh

The char pointers in 'struct cs_dsp_mock_coeff_def' are expected to point to C strings. They need to be terminated by a null byte. However the code does not allocate that trailing null byte and only works if by chance the allocation is followed by such a null byte. Refactor the repeated string allocation logic into a new helper which makes sure the terminating null is always present. It also makes the code more readable.

[PATCH v3 4/5] fprobe: Fix accounting of when to unregister from function graph

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> When adding a new fprobe, it will update the function hash to the functions the fprobe is attached to and register with function graph to have it call the registered functions. The fprobe_graph_active variable keeps track of the number of fprobes that are using function graph. If two fprobes attach to the same function, it increments the fprobe_graph_active for each of them. But when they are removed, the first fprobe to be removed will see that the function it is attached to is also used by another fprobe and it will not remove that function from function_graph. The logic will skip decrementing the fprobe_graph_active variable. This causes the fprobe_graph_active variable to not go to zero when all fprobes are removed, and in doing so it does not unregister from function graph. As the fgraph ops hash will now be empty, and an empty filter hash means all functions are enabled, this triggers function graph to add a callback to the fprobe infrastructure for every function! # echo "f:myevent1 kernel_clone" >> /sys/kernel/tracing/dynamic_events # echo "f:myevent2 kernel_clone%return" >> /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions kernel_clone (1) tramp: 0xffffffffc0024000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 # > /sys/kernel/tracing/dynamic_events # cat /sys/kernel/tracing/enabled_functions trace_initcall_start_cb (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 run_init_process (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 try_to_run_init_process (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 x86_pmu_show_pmu_cap (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 cleanup_rapl_pmus (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 uncore_free_pcibus_map (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 uncore_types_exit (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 uncore_pci_exit.part.0 (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 kvm_shutdown (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 vmx_dump_msrs (1) tramp: 0xffffffffc0026000 (function_trace_call+0x0/0x170) ->function_trace_call+0x0/0x170 [..] # cat /sys/kernel/tracing/enabled_functions | wc -l 54702 If a fprobe is being removed and all its functions are also traced by other fprobes, still decrement the fprobe_graph_active counter.
