[PATCH] soc: imx8m: Fix missing refcount decrement in error path for np

by Javier Carrasco

An error path was introduced without including the required call to of_node_put() to decrement the node's refcount and avoid leaking memory. If the call to of_clk_get_by_name() for 'clk' fails, the probe returns without decrementing the refcount. Use the automatic cleanup facility to fix the bug and protect the code against new error paths where the call to of_node_put() might be missing again.

This is a problem for s390x KVM, which explicitly remaps all PMD-mapped THPs to be PTE-mapped in s390_enable_sie()->thp_split_mm(), before starting the VM. For example, starting a VM backed on a file system with large folios supported makes the VM crash when the VM tries accessing such a mapping using KVM. Is it also a problem when the HW disabled THP using TRANSPARENT_HUGEPAGE_UNSUPPORTED? At least on x86 this would be the case without X86_FEATURE_PSE. In the future, we might be able to do better on s390x and only disallow PMD mappings -- what s390x and likely TRANSPARENT_HUGEPAGE_UNSUPPORTED really wants. For now, fix it by essentially performing the same check as would be done in __thp_vma_allowable_orders() or in shmem code, where this works as expected, and disallow PMD mappings, making us fallback to PTE mappings.

During testing, it was found that we can get PMD mappings in processes where THP (and more precisely, PMD mappings) are supposed to be disabled. While it works as expected for anon+shmem, the pagecache is the problematic bit. For s390 KVM this currently means that a VM backed by a file located on filesystem with large folio support can crash when KVM tries accessing the problematic page, because the readahead logic might decide to use a PMD-sized THP and faulting it into the page tables will install a PMD mapping, something that s390 KVM cannot tolerate. This might also be a problem with HW that does not support PMD mappings, but I did not try reproducing it. Fix it by respecting the ways to disable THPs when deciding whether we can install a PMD mapping. khugepaged should already be taking care of not collapsing if THPs are effectively disabled for the hw/process/vma.

[PATCH net v1 1] net: macb: Avoid 20s boot delay by skipping MDIO bus registration for fixed-link PHY

by Oleksij Rempel

A boot delay was introduced by commit 79540d133ed6 ("net: macb: Fix handling of fixed-link node"). This delay was caused by the call to `mdiobus_register()` in cases where a fixed-link PHY was present. The MDIO bus registration triggered unnecessary PHY address scans, leading to a 20-second delay due to attempts to detect Clause 45 (C45) compatible PHYs, despite no MDIO bus being attached. The commit 79540d133ed6 ("net: macb: Fix handling of fixed-link node") was originally introduced to fix a regression caused by commit 7897b071ac3b4 ("net: macb: convert to phylink"), which caused the driver to misinterpret fixed-link nodes as PHY nodes. This resulted in warnings like: mdio_bus f0028000.ethernet-ffffffff: fixed-link has invalid PHY address mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 0 ... mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 31 This patch reworks the logic to avoid registering and allocation of the MDIO bus when: - The device tree contains a fixed-link node. - There is no "mdio" child node in the device tree. If a child node named "mdio" exists, the MDIO bus will be registered to support PHYs attached to the MACB's MDIO bus. Otherwise, with only a fixed-link, the MDIO bus is skipped. Tested on a sama5d35 based system with a ksz8863 switch attached to macb0.

[PATCH v5 00/10] iio: add support for the ad3552r AXI DAC IP

by Angelo Dureghello

Purpose is to add ad3552r AXI DAC (fpga-based) support. The "ad3552r" AXI IP, a variant of the generic "DAC" AXI IP, has been created to reach the maximum speed (33MUPS) supported from the ad3552r. To obtain the maximum transfer rate, a custom IP core module has been implemented with a QSPI interface with DDR (Double Data Rate) mode. The design is actually using the DAC backend since the register map is the same of the generic DAC IP, except for some customized bitfields. For this reason, a new "compatible" has been added in adi-axi-dac.c. Also, backend has been extended with all the needed functions for this use case, keeping the names gneric. The following patch is actually applying to linux-iio/testing. --- Changes in v2: - use unsigned int on bus_reg_read/write - add a compatible in axi-dac backend for the ad3552r DAC IP - minor code alignment fixes - fix a return value not checked - change devicetree structure setting ad3552r-axi as a backend subnode - add synchronous_mode_available in the ABI doc Changes in v3: - changing AXI backend approach using a dac ip compatible - fdt bindings updates accordingly - fdt, ad3552r device must be a subnode of the backend - allow probe of child devices - passing QSPI bus access function by platform data - move synchronous mode as a fdt parameter - reorganizing defines in proper patches - fix make dt_binding_check errors - fix ad3552r maximum SPI speed - fix samplerate calulcation - minor code style fixes Changes in v4: - fix Kconfig - fix backend documentation - driver renamed to a more gneric "high speed" (ad3552r-hs) - restyled axi-dac register names - removed synchronous support, dead code (could be added in the future with David sugestions if needed) - renaming backend buffer enable/disable calls - using model_data in common code - using devm_add_action_or_reset - minor code style fixes Changes in v5: - patch 2/11 set before fix of ADI_DAC_R1_MODE patch - fix dt binding check error - patch 4/11 removed - fix stream enable/disable call names - fix axi-dac clock names - fix axi-dac platform device unregistering - minor code style fixes Signed-off-by: Angelo Dureghello <adureghello(a)baylibre.com> --- Angelo Dureghello (10): iio: dac: adi-axi-dac: fix wrong register bitfield iio: dac: adi-axi-dac: update register names dt-bindings: iio: dac: ad3552r: add iio backend support dt-bindings: iio: dac: adi-axi-dac: add ad3552r axi variant iio: backend: extend features iio: dac: adi-axi-dac: extend features iio: dac: ad3552r: changes to use FIELD_PREP iio: dac: ad3552r: extract common code (no changes in behavior intended) iio: dac: ad3552r: add high-speed platform driver iio: dac: adi-axi-dac: add registering of child fdt node .../devicetree/bindings/iio/dac/adi,ad3552r.yaml | 7 + .../devicetree/bindings/iio/dac/adi,axi-dac.yaml | 56 ++- drivers/iio/dac/Kconfig | 14 + drivers/iio/dac/Makefile | 3 +- drivers/iio/dac/ad3552r-common.c | 170 +++++++ drivers/iio/dac/ad3552r-hs.c | 526 +++++++++++++++++++++ drivers/iio/dac/ad3552r.c | 461 +++--------------- drivers/iio/dac/ad3552r.h | 207 ++++++++ drivers/iio/dac/adi-axi-dac.c | 483 ++++++++++++++++--- drivers/iio/industrialio-backend.c | 78 +++ include/linux/iio/backend.h | 17 + include/linux/platform_data/ad3552r-hs.h | 18 + 12 files changed, 1573 insertions(+), 467 deletions(-) --- base-commit: a620cae575523a8c922ad0842647ca38fc6ccd3c change-id: 20241008-wip-bl-ad3552r-axi-v0-iio-testing-3d15e90e1eb5 Best regards, -- Angelo Dureghello <adureghello(a)baylibre.com>

[PATCH] ASoC: qcom: sc7280: Fix missing Soundwire runtime stream alloc

by Krzysztof Kozlowski

Commit 15c7fab0e047 ("ASoC: qcom: Move Soundwire runtime stream alloc to soundcards") moved the allocation of Soundwire stream runtime from the Qualcomm Soundwire driver to each individual machine sound card driver, except that it forgot to update SC7280 card. Just like for other Qualcomm sound cards using Soundwire, the card driver should allocate and release the runtime. Otherwise sound playback will result in a NULL pointer dereference or other effect of uninitialized memory accesses (which was confirmed on SDM845 having similar issue).

[PATCH 6.1.y] rust: macros: provide correct provenance when constructing THIS_MODULE

by Boqun Feng

commit a5a3c952e82c1ada12bf8c55b73af26f1a454bd2 upstream. Currently while defining `THIS_MODULE` symbol in `module!()`, the pointer used to construct `ThisModule` is derived from an immutable reference of `__this_module`, which means the pointer doesn't have the provenance for writing, and that means any write to that pointer is UB regardless of data races or not. However, the usage of `THIS_MODULE` includes passing this pointer to functions that may write to it (probably in unsafe code), and this will create soundness issues. One way to fix this is using `addr_of_mut!()` but that requires the unstable feature "const_mut_refs". So instead of `addr_of_mut()!`, an extern static `Opaque` is used here: since `Opaque<T>` is transparent to `T`, an extern static `Opaque` will just wrap the C symbol (defined in a C compile unit) in an `Opaque`, which provides a pointer with writable provenance via `Opaque::get()`. This fix the potential UBs because of pointer provenance unmatched.

[PATCH 5.15.y 5.10.y 5.4.y] RDMA/rxe: Fix seg fault in rxe_comp_queue_pkt

by Sherry Yang

From: Bob Pearson <rpearsonhpe(a)gmail.com> [ Upstream commit 2b23b6097303ed0ba5f4bc036a1c07b6027af5c6 ] In rxe_comp_queue_pkt() an incoming response packet skb is enqueued to the resp_pkts queue and then a decision is made whether to run the completer task inline or schedule it. Finally the skb is dereferenced to bump a 'hw' performance counter. This is wrong because if the completer task is already running in a separate thread it may have already processed the skb and freed it which can cause a seg fault. This has been observed infrequently in testing at high scale. This patch fixes this by changing the order of enqueuing the packet until after the counter is accessed.

[PATCH 5.15.y] platform/x86: panasonic-laptop: Fix SINF array out of bounds accesses

by Sherry Yang

From: Hans de Goede <hdegoede(a)redhat.com> commit f52e98d16e9bd7dd2b3aef8e38db5cbc9899d6a4 upstream. The panasonic laptop code in various places uses the SINF array with index values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array is big enough. Not all panasonic laptops have this many SINF array entries, for example the Toughbook CF-18 model only has 10 SINF array entries. So it only supports the AC+DC brightness entries and mute. Check that the SINF array has a minimum size which covers all AC+DC brightness entries and refuse to load if the SINF array is smaller. For higher SINF indexes hide the sysfs attributes when the SINF array does not contain an entry for that attribute, avoiding show()/store() accessing the array out of bounds and add bounds checking to the probe() and resume() code accessing these.

[PATCH 1/1] nfsd: fix race between laundromat and free_stateid

by Olga Kornievskaia

There is a race between laundromat handling of revoked delegations and a client sending free_stateid operation. Laundromat thread finds that delegation has expired and needs to be revoked so it marks the delegation stid revoked and it puts it on a reaper list but then it unlock the state lock and the actual delegation revocation happens without the lock. Once the stid is marked revoked a racing free_stateid processing thread does the following (1) it calls list_del_init() which removes it from the reaper list and (2) frees the delegation stid structure. The laundromat thread ends up not calling the revoke_delegation() function for this particular delegation but that means it will no release the lock lease that exists on the file. Now, a new open for this file comes in and ends up finding that lease list isn't empty and calls nfsd_breaker_owns_lease() which ends up trying to derefence a freed delegation stateid.

[PATCH RFC v2] mm: Enforce the stack gap when changing inaccessible VMAs

by Jann Horn

As explained in the comment block this change adds, we can't tell what userspace's intent is when the stack grows towards an inaccessible VMA. We should ensure that, as long as code is compiled with something like -fstack-check, a stack overflow in this code can never cause the main stack to overflow into adjacent heap memory - so the bottom of a stack should never be directly adjacent to an accessible VMA. As suggested by Lorenzo, enforce this by blocking attempts to: - make an inaccessible VMA accessible with mprotect() when it is too close to a stack - replace an inaccessible VMA with another VMA using MAP_FIXED when it is too close to a stack I have a (highly contrived) C testcase for 32-bit x86 userspace with glibc that mixes malloc(), pthread creation, and recursion in just the right way such that the main stack overflows into malloc() arena memory, see the linked list post. I don't know of any specific scenario where this is actually exploitable, but it seems like it could be a security problem for sufficiently unlucky userspace. Link: https://lore.kernel.org/r/CAG48ez2v=r9-37JADA5DgnZdMLCjcbVxAjLt5eH5uoBohRdq… Suggested-by: Lorenzo Stoakes <lorenzo.stoakes(a)oracle.com> Fixes: 561b5e0709e4 ("mm/mmap.c: do not blow on PROT_NONE MAP_FIXED holes in the stack") Cc: stable(a)vger.kernel.org Signed-off-by: Jann Horn <jannh(a)google.com> --- This is an attempt at the alternate fix approach suggested by Lorenzo. This turned into more code than I would prefer to have for a scenario like this... Also, the way the gap is enforced in my patch for MAP_FIXED_NOREPLACE is a bit ugly. In the existing code, __get_unmapped_area() normally already enforces the stack gap even when it is called with a hint; but when MAP_FIXED_NOREPLACE is used, we kinda lie to __get_unmapped_area() and tell it we'll do a MAP_FIXED mapping (introduced in commit a4ff8e8620d3f when MAP_FIXED_NOREPLACE was created), then afterwards manually reject overlapping mappings. So I ended up also doing the gap check separately for MAP_FIXED_NOREPLACE.

[PATCH v2] x86/CPU/AMD: Only apply Zenbleed fix for Zen2 during late microcode load

by John Allen

A problem was introduced with commit f69759be251d ("x86/CPU/AMD: Move Zenbleed check to the Zen2 init function") where a bit in the DE_CFG MSR is getting set after a microcode late load. The problem seems to be that the microcode late load path calls into amd_check_microcode() and subsequently zen2_zenbleed_check(). Since the patch removes the cpu_has_amd_erratum() check from zen2_zenbleed_check(), this will cause all non-Zen2 CPUs to go through the function and set the bit in the DE_CFG MSR. Call into the zenbleed fix path on Zen2 CPUs only.

[PATCH] pinctrl: nuvoton: fix a double free in ma35_pinctrl_dt_node_to_map_func()

by Harshit Mogalapalli

'new_map' is allocated using devm_* which takes care of freeing the allocated data on device removal, call to .dt_free_map = pinconf_generic_dt_free_map double frees the map as pinconf_generic_dt_free_map() calls pinctrl_utils_free_map().

[PATCH v3] xhci: tegra: fix checked USB2 port number

If USB virtualizatoin is enabled, USB2 ports are shared between all Virtual Functions. The USB2 port number owned by an USB2 root hub in a Virtual Function may be less than total USB2 phy number supported by the Tegra XUSB controller.

[PATCH] arm64: dts: rockchip: Prevent thermal runaways in RK3308 SoC dtsi

by Dragan Simic

Until the TSADC, thermal zones, thermal trips and cooling maps are defined in the RK3308 SoC dtsi, none of the CPU OPPs except the slowest one may be enabled under any circumstances. Allowing the DVFS to scale the CPU cores up without even just the critical CPU thermal trip in place can rather easily result in thermal runaways and damaged SoCs, which is bad. Thus, leave only the lowest available CPU OPP enabled for now.

[PATCH] ASoC: qcom: sdm845: add missing soundwire runtime stream alloc

by Alexey Klimov

During the migration of Soundwire runtime stream allocation from the Qualcomm Soundwire controller to SoC's soundcard drivers the sdm845 soundcard was forgotten. At this point any playback attempt or audio daemon startup, for instance on sdm845-db845c (Qualcomm RB3 board), will result in stream pointer NULL dereference: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020 Mem abort info: ESR = 0x0000000096000004 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x04: level 0 translation fault Data abort info: ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000 CM = 0, WnR = 0, TnD = 0, TagAccess = 0 GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 user pgtable: 4k pages, 48-bit VAs, pgdp=0000000101ecf000 [0000000000000020] pgd=0000000000000000, p4d=0000000000000000 Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP Modules linked in: ...

[PATCH V2] x86/apic: Stop the TSC Deadline timer during lapic timer shutdown

by Zhang Rui

This 12-year-old bug prevents some modern processors from achieving maximum power savings during suspend. For example, Lunar Lake systems gets 0% package C-states during suspend to idle and this causes energy star compliance tests to fail. According to Intel SDM, for the local APIC timer, 1. "The initial-count register is a read-write register. A write of 0 to the initial-count register effectively stops the local APIC timer, in both one-shot and periodic mode." 2. "In TSC deadline mode, writes to the initial-count register are ignored; and current-count register always reads 0. Instead, timer behavior is controlled using the IA32_TSC_DEADLINE MSR." "In TSC-deadline mode, writing 0 to the IA32_TSC_DEADLINE MSR disarms the local-APIC timer." Stop the TSC Deadline timer in lapic_timer_shutdown() by writing 0 to MSR_IA32_TSC_DEADLINE.

From: Oliver Neukum <oneukum(a)suse.com> commit 8d2b1a1ec9f559d30b724877da4ce592edc41fdc upstream. A broken device may give an extreme offset like 0xFFF0 and a reasonable length for a fragment. In the sanity check as formulated now, this will create an integer overflow, defeating the sanity check. Both offset and offset + len need to be checked in such a manner that no overflow can occur.

[PATCH 4.19] net: ipv6: ensure we call ipv6_mc_down() at most once

by hsimeliere.opensource＠witekio.com

From: "j.nixdorf(a)avm.de" <j.nixdorf(a)avm.de> commit 9995b408f17ff8c7f11bc725c8aa225ba3a63b1c upstream. There are two reasons for addrconf_notify() to be called with NETDEV_DOWN: either the network device is actually going down, or IPv6 was disabled on the interface. If either of them stays down while the other is toggled, we repeatedly call the code for NETDEV_DOWN, including ipv6_mc_down(), while never calling the corresponding ipv6_mc_up() in between. This will cause a new entry in idev->mc_tomb to be allocated for each multicast group the interface is subscribed to, which in turn leaks one struct ifmcaddr6 per nontrivial multicast group the interface is subscribed to. The following reproducer will leak at least $n objects: ip addr add ff2e::4242/32 dev eth0 autojoin sysctl -w net.ipv6.conf.eth0.disable_ipv6=1 for i in $(seq 1 $n); do ip link set up eth0; ip link set down eth0 done Joining groups with IPV6_ADD_MEMBERSHIP (unprivileged) or setting the sysctl net.ipv6.conf.eth0.forwarding to 1 (=> subscribing to ff02::2) can also be used to create a nontrivial idev->mc_list, which will the leak objects with the right up-down-sequence. Based on both sources for NETDEV_DOWN events the interface IPv6 state should be considered: - not ready if the network interface is not ready OR IPv6 is disabled for it - ready if the network interface is ready AND IPv6 is enabled for it The functions ipv6_mc_up() and ipv6_down() should only be run when this state changes. Implement this by remembering when the IPv6 state is ready, and only run ipv6_mc_down() if it actually changed from ready to not ready. The other direction (not ready -> ready) already works correctly, as: - the interface notification triggered codepath for NETDEV_UP / NETDEV_CHANGE returns early if ipv6 is disabled, and - the disable_ipv6=0 triggered codepath skips fully initializing the interface as long as addrconf_link_ready(dev) returns false - calling ipv6_mc_up() repeatedly does not leak anything Fixes: 3ce62a84d53c ("ipv6: exit early in addrconf_notify() if IPv6 is disabled") Signed-off-by: Johannes Nixdorf <j.nixdorf(a)avm.de> Signed-off-by: David S.

[PATCH 0/3] drm: logicvc: add of_node_put() and switch to a more secure approach

by Javier Carrasco

This driver has faced several issues due to the wrong or missing usage of of_node_put() to release device nodes after they are no longer required. The first implementation was missing the of_node_put() for 'layers_node', and it put 'layer_node' twice. Then commit 'd3a453416270 ("drm: fix device_node_continue.cocci warnings")' removed the extra of_node_put(layer_node), which would have been ok if it had stayed only in the error path. Later, commit 'e9fcc60ddd29 ("drm/logicvc: add missing of_node_put() in logicvc_layers_init()")' added the missing of_node_put(layers_node), but not the one for the child node. It should be clear how easy someone can mess up with this pattern, especially with variables that have similar names. To fix the bug for stable kernels, and provide a more robust solution that accounts for new error paths, this series provides a first patch with the classical approach of adding the missing of_node_put(), and two more patches to use the cleanup attribute and avoid issues with device nodes again.

[PATCH 5.10.y 0/4] Backport fix commit for kprobe_non_uniq_symbol.tc test failure

by Sherry Yang

5.10.y backported the commit 09bcf9254838 ("selftests/ftrace: Add new test case which checks non unique symbol") which added a new test case to check non-unique symbol. However, 5.10.y didn't backport the kernel commit b022f0c7e404 ("tracing/kprobes: Return EADDRNOTAVAIL when func matches several symbols")to support the functionality from kernel side. Backport it in this patch series. The first two patches are presiquisites. The 4th commit is a fix commit for the 3rd one. Build and test case passed.

[PATCH v6 5/8] clk: qcom: gcc-x1e80100: Fix halt_check for pipediv2 clocks

by Qiang Yu

The pipediv2_clk's source from the same mux as pipe clock. So they have same limitation, which is that the PHY sequence requires to enable these local CBCs before the PHY is actually outputting a clock to them. This means the clock won't actually turn on when we vote them. Hence, let's skip the halt bit check of the pipediv2_clk, otherwise pipediv2_clk may stuck at off state during bootup.

The LBR bit is only removed from xfeatures_mask_independent when LBR is not supported by the CPU, but there is no validation of XSTATE support. If XSAVES does not support LBR the write to IA32_XSS causes a #GP fault, leaving the state of IA32_XSS unchanged, i.e. zero. The fault is handled with a warning and the boot continues. Consequently the next XRSTORS which tries to restore supervisor state fails with #GP because the RFBM has zero for all supervisor features, which does not match the XCOMP_BV field. As XFEATURE_MASK_FPSTATE includes supervisor features setting up the FPU causes a #GP, which ends up in fpu_reset_from_exception_fixup(). That fails due to the same problem resulting in recursive #GPs until the kernel runs out of stack space and double faults. Prevent this by storing the supported independent features in fpu_kernel_cfg during XSTATE initialization and use that cached value for retrieving the independent feature bits to be written into IA32_XSS.

[PATCH] platform/chrome: cross_ec_type: fix missing fwnode reference decrement

by Javier Carrasco

The device_for_each_child_node() macro requires explicit calls to fwnode_handle_put() upon early exits (return, break, goto) to decrement the fwnode's refcount, and avoid levaing a node reference behind. Add the missing fwnode_handle_put() after the common label for all error paths. Cc: stable(a)vger.kernel.org Fixes: fdc6b21e2444 ("platform/chrome: Add Type C connector class driver") Signed-off-by: Javier Carrasco <javier.carrasco.cruz(a)gmail.com> --- I usually switch to the scoped variant of the macro to fix such issues, but given that the fix is relevant for stable kernels, I have provided the "classical" approach by adding the missing fwnode_handle_put(). If switching to the scoped variant is desired, please let me know. This driver and cross_typec_switch could be easily converted. By the way, I wonder why all error paths are redirected to the same label to unregister ports, even before registering them (which seems to be harmless because unregistered ports are ignored, but still). With this fix, that jump to the label is definitely required, but if the scoped variant is used, maybe some simple returns would be enough. --- drivers/platform/chrome/cros_ec_typec.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/platform/chrome/cros_ec_typec.c b/drivers/platform/chrome/cros_ec_typec.c index c7781aea0b88..f1324466efac 100644 --- a/drivers/platform/chrome/cros_ec_typec.c +++ b/drivers/platform/chrome/cros_ec_typec.c @@ -409,6 +409,7 @@ static int cros_typec_init_ports(struct cros_typec_data *typec) return 0; unregister_ports: + fwnode_handle_put(fwnode); cros_unregister_ports(typec); return ret; } --- base-commit: b6270c3bca987530eafc6a15f9d54ecd0033e0e3 change-id: 20241009-cross_ec_typec_fwnode_handle_put-9f13b4bd467f Best regards, -- Javier Carrasco <javier.carrasco.cruz(a)gmail.com>

[PATCHSET v5.0 3/9] xfs: metadata inode directory trees

by Darrick J. Wong

Hi all, This series delivers a new feature -- metadata inode directories. This is a separate directory tree (rooted in the superblock) that contains only inodes that contain filesystem metadata. Different metadata objects can be looked up with regular paths. Start by creating xfs_imeta{dir,file}* functions to mediate access to the metadata directory tree. By the end of this mega series, all existing metadata inodes (rt+quota) will use this directory tree instead of the superblock. Next, define the metadir on-disk format, which consists of marking inodes with a new iflag that says they're metadata. This prevents bulkstat and friends from ever getting their hands on fs metadata files. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. This has been running on the djcloud for months with no problems. Enjoy!

[PATCH v2] usb: dwc3: core: Fix system suspend on TI AM62 platforms

by Roger Quadros

Since commit 6d735722063a ("usb: dwc3: core: Prevent phy suspend during init"), system suspend is broken on AM62 TI platforms. Before that commit, both DWC3_GUSB3PIPECTL_SUSPHY and DWC3_GUSB2PHYCFG_SUSPHY bits (hence forth called 2 SUSPHY bits) were being set during core initialization and even during core re-initialization after a system suspend/resume. These bits are required to be set for system suspend/resume to work correctly on AM62 platforms. Since that commit, the 2 SUSPHY bits are not set for DEVICE/OTG mode if gadget driver is not loaded and started. For Host mode, the 2 SUSPHY bits are set before the first system suspend but get cleared at system resume during core re-init and are never set again. This patch resovles these two issues by ensuring the 2 SUSPHY bits are set before system suspend and restored to the original state during system resume.

[PATCH v3 5/9] serial: qcom-geni: fix receiver enable

by Johan Hovold

The receiver is supposed to be enabled in the startup() callback and not in set_termios() which is called also during console setup. This specifically avoids accepting input before the port has been opened (and interrupts enabled), something which can also break the GENI firmware (cancel fails and after abort, the "stale" counter handling appears to be broken so that later input is not processed until twelve chars have been received). There also does not appear to be any need to keep the receiver disabled while updating the port settings. Since commit 6f3c3cafb115 ("serial: qcom-geni: disable interrupts during console writes") the calls to manipulate the secondary interrupts, which were done without holding the port lock, can also lead to the receiver being left disabled when set_termios() races with the console code (e.g. when init opens the tty during boot). This can manifest itself as a serial getty not accepting input. The calls to stop and start rx in set_termios() can similarly race with DMA completion and, for example, cause the DMA buffer to be unmapped twice or the mapping to be leaked.

[PATCH] mm: Enforce a minimal stack gap even against inaccessible VMAs

by Jann Horn

As explained in the comment block this change adds, we can't tell what userspace's intent is when the stack grows towards an inaccessible VMA. I have a (highly contrived) C testcase for 32-bit x86 userspace with glibc that mixes malloc(), pthread creation, and recursion in just the right way such that the main stack overflows into malloc() arena memory. (Let me know if you want me to share that.) I don't know of any specific scenario where this is actually exploitable, but it seems like it could be a security problem for sufficiently unlucky userspace. I believe we should ensure that, as long as code is compiled with something like -fstack-check, a stack overflow in it can never cause the main stack to overflow into adjacent heap memory. My fix effectively reverts the behavior for !vma_is_accessible() VMAs to the behavior before commit 1be7107fbe18 ("mm: larger stack guard gap, between vmas"), so I think it should be a fairly safe change even in case A.

[PATCH] drm/vblank: Require a driver register vblank support for 0 or all CRTCs

by Lyude Paul

Currently, there's nothing actually stopping a driver from only registering vblank support for some of it's CRTCs and not for others. As far as I can tell, this isn't really defined behavior on the C side of things - as the documentation explicitly mentions to not use drm_vblank_init() if you don't have vblank support - since DRM then steps in and adds its own vblank emulation implementation. So, let's fix this edge case and check to make sure it's all or none.

[PATCH stable 6.1] devlink: Fix RCU stall when unregistering a devlink instance

by Ido Schimmel

When a devlink instance is unregistered the following happens (among other things): t0 - The instance is marked with 'DEVLINK_UNREGISTERING'. t1 - Blocking until an RCU grace period passes. t2 - The 'DEVLINK_UNREGISTERING' mark is cleared from the instance. When iterating over devlink instances (f.e., when requesting a dump of available instances) and encountering an instance that is currently being unregistered, the current code will loop around until the 'DEVLINK_UNREGISTERING' mark is cleared. The iteration over devlink instances happens in an RCU critical section, so if the instance that is currently being unregistered was encountered between t0 and t1, the system will deadlock and RCU stalls will be reported [1]. The task unregistering the instance will forever wait for an RCU grace period to pass and the task iterating over the instances will forever wait for the mark to be cleared. The issue can be reliably reproduced by increasing the time window between t0 and t1 (used a 60 seconds sleep) and running the following reproducer [2]. Fix by skipping over instances that are currently being unregistered.

[PATCH net] udp: Compute L4 checksum as usual when not segmenting the skb

by Jakub Sitnicki

If: 1) the user requested USO, but 2) there is not enough payload for GSO to kick in, and 3) the egress device doesn't offer checksum offload, then we want to compute the L4 checksum in software early on. In the case when we taking the GSO path, but it has been requested, the software checksum fallback in skb_segment doesn't get a chance to compute the full checksum, if the egress device can't do it. As a result we end up sending UDP datagrams with only a partial checksum filled in, which the peer will discard.

[PATCH v6 0/4] ov08x40: Enable use of ov08x40 on Qualcomm X1E80100 CRD

by Bryan O'Donoghue

Changes in v6: - As I was applying a suggested fix from V5 of this series to other yaml schema in media/i2c it seemed to me that there were a number of properties that would be affected by converting properites: endpoint: additionalProperties: false to unevaluatedProperites: false I pinged Laurent, Sakari, Rob and Krsysztof about that leading to: link-frequencies: true is considered a valid hardware description. We don't want everything in /schemas/media/video-interfaces.yaml to be valid for each of the port{} descriptions for sensors so: a) use additionalProperties: false listing valid properties directly. b) Fixup various schema to list the valid properties in line with above. - Convert unevaluatedProperites: false to additionalProperties: false Laurent - This isn't exactly what Krsysztof gave his RB for so, I've omitted that - Add remote-endpoint: true to port{} - required as result of additionalProperties: false - I'll still follow up this series with a more general fix in-line with the above as TBH I just copy/pasted from some upstream yaml so it looks like a more general remediation is warranted, saving someone else from repeating my mistake. - Add remote-endpoint: true to port{} - required as result of additionalProperties: false - Use schemas/media/video-interface-devices.yaml# with unevaluatedProperites: false So that rotation and orientation are valid - bod - Link to v5: https://lore.kernel.org/r/20241005-b4-master-24-11-25-ov08x40-v5-0-5f1eb2e1… Changes in v5: - Fixes smatch CI splat - Link to v4: https://lore.kernel.org/r/20241003-b4-master-24-11-25-ov08x40-v4-0-7ee2c45f… Changes in v4: - Drops link-frequencies from properties: as discussed here: https://lore.kernel.org/r/Zv6STSKeNNlT83ux@kekkonen.localdomain - Link to v3: https://lore.kernel.org/r/20241002-b4-master-24-11-25-ov08x40-v3-0-483bcdcf… Changes in v3: - Drops assigned-clock-* from description retains in example - Sakari, Krzysztof - Updates example fake clock names to ov08x40_* instead of copy/paste ov9282_clk -> ov08x40_clk, ov9282_clk_parent -> ov08x40_clk_parent - bod - Link to v2: https://lore.kernel.org/r/20241001-b4-master-24-11-25-ov08x40-v2-0-e478976b… Changes in v2: - Drops "-" in ovti,ov08x40.yaml after description: - Rob - Adds ":" after first line of description text - Rob - dts -> DT in commit log - Rob - Removes dependency on 'xvclk' as a name in yaml and driver - Sakari - Uses assigned-clock, assigned-clock-parents and assigned-clock-rates - Sakari - Drops clock-frequency - Sakarai, Krzysztof - Drops dovdd-supply, avdd-supply, dvdd-supply and reset-gpios as required, its perfectly possible not to have the reset GPIO or the power rails under control of the SoC. - bod - Link to v1: https://lore.kernel.org/r/20240926-b4-master-24-11-25-ov08x40-v1-0-e4d5fbd3… V1: This series brings fixes and updates to ov08x40 which allows for use of this sensor on the Qualcomm x1e80100 CRD but also on any other dts based system. Firstly there's a fix for the pseudo burst mode code that was added in 8f667d202384 ("media: ov08x40: Reduce start streaming time"). Not every I2C controller can handle an arbitrary sized write, this is the case on Qualcomm CAMSS/CCI I2C sensor interfaces which limit the transaction size and communicate this limit via I2C quirks. A simple fix to optionally break up the large submitted burst into chunks not exceeding adapter->quirk size fixes. Secondly then is addition of a yaml description for the ov08x40 and extension of the driver to support OF probe and powering on of the power rails from the driver instead of from ACPI. Once done the sensor works without further modification on the Qualcomm x1e80100 CRD.

[PATCH v2] ASoC: dapm: avoid container_of() to get component

by Benjamin Bara

From: Benjamin Bara <benjamin.bara(a)skidata.com> The current implementation does not work for widgets of DAPMs without component, as snd_soc_dapm_to_component() requires it. If the widget is directly owned by the card, e.g. as it is the case for the tegra implementation, the call leads to UB. Therefore directly access the component of the widget's DAPM to be able to check if a component is available. Fixes: f82eb06a40c8 ("ASoC: tegra: machine: Handle component name prefix") Cc: stable(a)vger.kernel.org # v6.7+ Signed-off-by: Benjamin Bara <benjamin.bara(a)skidata.com> --- Hi! I handled the new patch as V2 of the initial one, although it has a different summary. Hope this is fine. --- Changes in v2: - fix snd_soc_dapm_widget_name_cmp() instead of reverting commit - don't pick up R-b of Krzysztof, as different implementation - Link to v1: https://lore.kernel.org/r/20241007-tegra-dapm-v1-1-bede7983fa76@skidata.com --- sound/soc/soc-dapm.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/sound/soc/soc-dapm.c b/sound/soc/soc-dapm.c index 9330f1a3f7589dc467c04238830f2009a619a998..c34934c31ffec3970b34b24dcaa0826dfb7d8e86 100644 --- a/sound/soc/soc-dapm.c +++ b/sound/soc/soc-dapm.c @@ -2785,10 +2785,10 @@ EXPORT_SYMBOL_GPL(snd_soc_dapm_update_dai); int snd_soc_dapm_widget_name_cmp(struct snd_soc_dapm_widget *widget, const char *s) { - struct snd_soc_component *component = snd_soc_dapm_to_component(widget->dapm); + struct snd_soc_component *component = widget->dapm->component; const char *wname = widget->name; - if (component->name_prefix) + if (component && component->name_prefix) wname += strlen(component->name_prefix) + 1; /* plus space */ return strcmp(wname, s); --- base-commit: 8cf0b93919e13d1e8d4466eb4080a4c4d9d66d7b change-id: 20241007-tegra-dapm-ef969b8f762a Best regards, -- Benjamin Bara <benjamin.bara(a)skidata.com>

Linux 6.6.56

by Greg Kroah-Hartman

I'm announcing the release of the 6.6.56 kernel. This fixes a build error in perf that I should have caught before 6.6.55 was released (my fault, it was correctly reported...). If you do not use the perf tool in the 6.6.y tree, there is no need to upgrade. The updated 6.6.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.6.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Makefile | 4 ++-- tools/perf/util/machine.c | 17 ++--------------- tools/perf/util/thread.c | 4 ---- tools/perf/util/thread.h | 1 - 4 files changed, 4 insertions(+), 22 deletions(-) Greg Kroah-Hartman (2): Revert "perf callchain: Fix stitch LBR memory leaks" Linux 6.6.56

Linux 6.10.14

by Greg Kroah-Hartman

---------------------------- Note, this is the LAST 6.10.y kernel to be released. There will not be any more 6.10.y releases and this branch is now end-of-life and you should move to the 6.11.y branch at this point in time. ---------------------------- I'm announcing the release of the 6.10.14 kernel. All users of the 6.10 kernel series must upgrade. The updated 6.10.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-6.10.y and can be browsed at the normal kernel.org git web browser:

[PATCH] leds: lp55xx: Fix check for invalid channel number

by Michal Vokáč

Prior to commit 92a81562e695 ("leds: lp55xx: Add multicolor framework support to lp55xx") the reg property (chan_nr) was parsed and stored as it was. Then, in lp55xx_init_led() function, it was checked if it is within valid range. In case it was not, an error message was printed and the driver probe failed. With the mentioned commit the reg property is checked right after it is read from the device tree. Comparison to the upper range is not correct though. Valid reg values are 0 to (max_channel - 1). So in case the parsed value is out of this (wrong) range the probe just fails and no error message is shown. Fix it by using proper comparison and print a message in case of an error. The check that is done in lp55xx_init_led() function is now redundant and can be removed.

[PATCH v1 1/1] ufs: core: set SDEV_OFFLINE when ufs shutdown.

by Seunghwan Baek

There is a history of dead lock as reboot is performed at the beginning of booting. SDEV_QUIESCE was set for all lu's scsi_devices by ufs shutdown, and at that time the audio driver was waiting on blk_mq_submit_bio holding a mutex_lock while reading the fw binary. After that, a deadlock issue occurred while audio driver shutdown was waiting for mutex_unlock of blk_mq_submit_bio. To solve this, set SDEV_OFFLINE for all lus except wlun, so that any i/o that comes down after a ufs shutdown will return an error.

This confuses region_intersects(), which expects all "System RAM" resources to be at the top level of iomem_resource. This can lead to bugs. For example, when the following command line is executed to write some memory in CXL memory range via /dev/mem, $ dd if=data of=/dev/mem bs=$((1 << 10)) seek=$((0x490000000 >> 10)) count=1 dd: error writing '/dev/mem': Bad address 1+0 records in 0+0 records out 0 bytes copied, 0.0283507 s, 0.0 kB/s the command fails as expected. However, the error code is wrong. It should be "Operation not permitted" instead of "Bad address". More seriously, the /dev/mem permission checking in devmem_is_allowed() passes incorrectly. Although the accessing is prevented later because ioremap() isn't allowed to map system RAM, it is a potential security issue. During command executing, the following warning is reported in the kernel log for calling ioremap() on system RAM. ioremap on RAM at 0x0000000490000000 - 0x0000000490000fff WARNING: CPU: 2 PID: 416 at arch/x86/mm/ioremap.c:216 __ioremap_caller.constprop.0+0x131/0x35d Call Trace: memremap+0xcb/0x184 xlate_dev_mem_ptr+0x25/0x2f write_mem+0x94/0xfb vfs_write+0x128/0x26d ksys_write+0xac/0xfe do_syscall_64+0x9a/0xfd entry_SYSCALL_64_after_hwframe+0x4b/0x53 The details of command execution process are as follows. In the above resource tree, "System RAM" is a descendant of "CXL Window 0" instead of a top level resource. So, region_intersects() will report no System RAM resources in the CXL memory region incorrectly, because it only checks the top level resources. Consequently, devmem_is_allowed() will return 1 (allow access via /dev/mem) for CXL memory region incorrectly. Fortunately, ioremap() doesn't allow to map System RAM and reject the access. So, region_intersects() needs to be fixed to work correctly with the resource tree with "System RAM" not at top level as above. To fix it, if we found a unmatched resource in the top level, we will continue to search matched resources in its descendant resources. So, we will not miss any matched resources in resource tree anymore. In the new implementation, an example resource tree |------------- "CXL Window 0" ------------| |-- "System RAM" --| will behave similar as the following fake resource tree for region_intersects(, IORESOURCE_SYSTEM_RAM, ), |-- "System RAM" --||-- "CXL Window 0a" --| Where "CXL Window 0a" is part of the original "CXL Window 0" that isn't covered by "System RAM".

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

by Guo Xuenan

commit 575689fc0ffa6c4bb4e72fd18e31a6525a6124e0 upstream. xfs log io error will trigger xlog shut down, and end_io worker call xlog_state_shutdown_callbacks to unpin and release the buf log item.

[PATCH 6.1] Drivers: hv: vmbus: Leak pages if set_memory_encrypted() fails

by Xiangyu Chen

From: Rick Edgecombe <rick.p.edgecombe(a)intel.com> In CoCo VMs it is possible for the untrusted host to cause set_memory_encrypted() or set_memory_decrypted() to fail such that an error is returned and the resulting memory is shared. Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page allocator, which could lead to functional or security issues. VMBus code could free decrypted pages if set_memory_encrypted()/decrypted() fails. Leak the pages if this happens.

[PATCH] spmi: pmic-arb: fix return path in for_each_available_child_of_node()

by Javier Carrasco

This loop requires explicit calls to of_node_put() upon early exits (break, goto, return) to decrement the child refcounter and avoid memory leaks if the child is not required out of the loop. A more robust solution is using the scoped variant of the macro, which automatically calls of_node_put() when the child goes out of scope.

[PATCH 1/1] nfsd: fix possible badness in FREE_STATEID

by Olga Kornievskaia

When multiple FREE_STATEIDs are sent for the same delegation stateid, it can lead to a possible either use-after-tree or counter refcount underflow errors. In nfsd4_free_stateid() under the client lock we find a delegation stateid, however the code drops the lock before calling nfs4_put_stid(), that allows another FREE_STATE to find the stateid again. The first one will proceed to then free the stateid which leads to either use-after-free or decrementing already zerod counter.

by Alexander Lobakin

kthread_create_on_cpu() always requires format string to contain one '%u' at the end, as it automatically adds the CPU ID when passing it to kthread_create_on_node(). The former isn't marked as __printf() as it's not printf-like itself, which effectively hides this from the compiler. If you convert this function to printf-like, you'll see the following: In file included from drivers/firmware/psci/psci_checker.c:15: drivers/firmware/psci/psci_checker.c: In function 'suspend_tests': drivers/firmware/psci/psci_checker.c:401:48: warning: too many arguments for format [-Wformat-extra-args] 401 | "psci_suspend_test"); | ^~~~~~~~~~~~~~~~~~~ drivers/firmware/psci/psci_checker.c:400:32: warning: data argument not used by format string [-Wformat-extra-args] 400 | (void *)(long)cpu, cpu, | ^ 401 | "psci_suspend_test"); | ~~~~~~~~~~~~~~~~~~~ Add the missing format literal to fix this. Now the corresponding kthread will be named as "psci_suspend_test-<cpuid>", as it's meant by kthread_create_on_cpu().

[PATCH v3 4/9] serial: qcom-geni: fix dma rx cancellation

by Johan Hovold

Make sure to wait for the DMA transfer to complete when cancelling the rx command on stop_rx(). This specifically prevents the DMA completion interrupt from firing after rx has been restarted, something which can lead to an IOMMU fault and hosed rx when the interrupt handler unmaps the DMA buffer for the new command: qcom_geni_serial 988000.serial: serial engine reports 0 RX bytes in! arm-smmu 15000000.iommu: FSR = 00000402 [Format=2 TF], SID=0x563 arm-smmu 15000000.iommu: FSYNR0 = 00210013 [S1CBNDX=33 WNR PLVL=3] Bluetooth: hci0: command 0xfc00 tx timeout Bluetooth: hci0: Reading QCA version information failed (-110) Also add the missing state machine reset which is needed in case cancellation fails.

[PATCH v3 2/9] serial: qcom-geni: revert broken hibernation support

by Johan Hovold

This reverts commit 35781d8356a2eecaa6074ceeb80ee22e252fcdae. Hibernation is not supported on Qualcomm platforms with mainline kernels yet a broken vendor implementation for the GENI serial driver made it upstream. This is effectively dead code that cannot be tested and should just be removed, but if these paths were ever hit for an open non-console port they would crash the machine as the driver would fail to enable clocks during restore() (i.e. all ports would have to be closed by drivers and user space before hibernating the system to avoid this as a comment in the code hinted at). The broken implementation also added a random call to enable the receiver in the port setup code where it does not belong and which enables the receiver prematurely for console ports.

[PATCH] mm/mremap: Fix move_normal_pmd/retract_page_tables race

by Jann Horn

In mremap(), move_page_tables() looks at the type of the PMD entry and the specified address range to figure out by which method the next chunk of page table entries should be moved. At that point, the mmap_lock is held in write mode, but no rmap locks are held yet. For PMD entries that point to page tables and are fully covered by the source address range, move_pgt_entry(NORMAL_PMD, ...) is called, which first takes rmap locks, then does move_normal_pmd(). move_normal_pmd() takes the necessary page table locks at source and destination, then moves an entire page table from the source to the destination. The problem is: The rmap locks, which protect against concurrent page table removal by retract_page_tables() in the THP code, are only taken after the PMD entry has been read and it has been decided how to move it. So we can race as follows (with two processes that have mappings of the same tmpfs file that is stored on a tmpfs mount with huge=advise); note that process A accesses page tables through the MM while process B does it through the file rmap: process A process B ========= ========= mremap mremap_to move_vma move_page_tables get_old_pmd alloc_new_pmd *** PREEMPT *** madvise(MADV_COLLAPSE) do_madvise madvise_walk_vmas madvise_vma_behavior madvise_collapse hpage_collapse_scan_file collapse_file retract_page_tables i_mmap_lock_read(mapping) pmdp_collapse_flush i_mmap_unlock_read(mapping) move_pgt_entry(NORMAL_PMD, ...) take_rmap_locks move_normal_pmd drop_rmap_locks When this happens, move_normal_pmd() can end up creating bogus PMD entries in the line `pmd_populate(mm, new_pmd, pmd_pgtable(pmd))`. The effect depends on arch-specific and machine-specific details; on x86, you can end up with physical page 0 mapped as a page table, which is likely exploitable for user->kernel privilege escalation. Fix the race by letting process B recheck that the PMD still points to a page table after the rmap locks have been taken. Otherwise, we bail and let the caller fall back to the PTE-level copying path, which will then bail immediately at the pmd_none() check. Bug reachability: Reaching this bug requires that you can create shmem/file THP mappings - anonymous THP uses different code that doesn't zap stuff under rmap locks. File THP is gated on an experimental config flag (CONFIG_READ_ONLY_THP_FOR_FS), so on normal distro kernels you need shmem THP to hit this bug. As far as I know, getting shmem THP normally requires that you can mount your own tmpfs with the right mount flags, which would require creating your own user+mount namespace; though I don't know if some distros maybe enable shmem THP by default or something like that. Bug impact: This issue can likely be used for user->kernel privilege escalation when it is reachable.

[PATCH v2] ata: libata: avoid superfluous disk spin down + spin up during hibernation

by Niklas Cassel

A user reported that commit aa3998dbeb3a ("ata: libata-scsi: Disable scsi device manage_system_start_stop") introduced a spin down + immediate spin up of the disk both when entering and when resuming from hibernation. This behavior was not there before, and causes an increased latency both when when entering and when resuming from hibernation. Hibernation is done by three consecutive PM events, in the following order: 1) PM_EVENT_FREEZE 2) PM_EVENT_THAW 3) PM_EVENT_HIBERNATE Commit aa3998dbeb3a ("ata: libata-scsi: Disable scsi device manage_system_start_stop") modified ata_eh_handle_port_suspend() to call ata_dev_power_set_standby() (which spins down the disk), for both event PM_EVENT_FREEZE and event PM_EVENT_HIBERNATE. Documentation/driver-api/pm/devices.rst, section "Entering Hibernation", explicitly mentions that PM_EVENT_FREEZE does not have to be put the device in a low-power state, and actually recommends not doing so. Thus, let's not spin down the disk on PM_EVENT_FREEZE. (The disk will instead be spun down during the subsequent PM_EVENT_HIBERNATE event.) This way, PM_EVENT_FREEZE will behave as it did before commit aa3998dbeb3a ("ata: libata-scsi: Disable scsi device manage_system_start_stop"), while PM_EVENT_HIBERNATE will continue to spin down the disk. This will avoid the superfluous spin down + spin up when entering and resuming from hibernation, while still making sure that the disk is spun down before actually entering hibernation.

[PATCH v2 4/7] serial: qcom-geni: fix receiver enable

by Johan Hovold

The receiver should be enabled in the startup() callback and there is no need to stop it on every termios update. Since commit 6f3c3cafb115 ("serial: qcom-geni: disable interrupts during console writes") the calls to manipulate the secondary interrupts, which were done without holding the port lock, can lead to the receiver being left disabled when set_termios() races with the console code (e.g. when init opens the tty during boot). The calls to stop and start rx in set_termios() can similarly race with DMA completion and, for example, cause the DMA buffer to be unmapped twice or the mapping to be leaked.

[PATCH v2] drm/amdgpu: prevent BO_HANDLES error from being overwritten

by Mohammed Anees

Before this patch, if multiple BO_HANDLES chunks were submitted, the error -EINVAL would be correctly set but could be overwritten by the return value from amdgpu_cs_p1_bo_handles(). This patch ensures that if there are multiple BO_HANDLES, we stop.

[PATCH v5.10-v5.4] btrfs: get rid of warning on transaction commit when using flushoncommit

by hsimeliere.opensource＠witekio.com

From: Filipe Manana <fdmanana(a)suse.com> commit a0f0cf8341e34e5d2265bfd3a7ad68342da1e2aa upstream. When using the flushoncommit mount option, during almost every transaction commit we trigger a warning from __writeback_inodes_sb_nr(): $ cat fs/fs-writeback.c: (...) static void __writeback_inodes_sb_nr(struct super_block *sb, ... { (...) WARN_ON(!rwsem_is_locked(&sb->s_umount)); (...) } (...) The trace produced in dmesg looks like the following: [947.473890] WARNING: CPU: 5 PID: 930 at fs/fs-writeback.c:2610 __writeback_inodes_sb_nr+0x7e/0xb3 [947.481623] Modules linked in: nfsd nls_cp437 cifs asn1_decoder cifs_arc4 fscache cifs_md4 ipmi_ssif [947.489571] CPU: 5 PID: 930 Comm: btrfs-transacti Not tainted 95.16.3-srb-asrock-00001-g36437ad63879 #186 [947.497969] RIP: 0010:__writeback_inodes_sb_nr+0x7e/0xb3 [947.502097] Code: 24 10 4c 89 44 24 18 c6 (...)

This change was made by commit ce8ea7cc6eb313 ("btrfs: don't call btrfs_start_delalloc_roots in flushoncommit"). After that change we started producing that warning, and every now and then a user reports this since the warning happens too often, it spams dmesg/syslog, and a user is unsure if this reflects any problem that might compromise the filesystem's reliability. We can not just lock the sb->s_umount semaphore before calling writeback_inodes_sb(), because that would at least deadlock with filesystem freezing, since at fs/super.c:freeze_super() sync_filesystem() is called while we are holding that semaphore in write mode, and that can trigger a transaction commit, resulting in a deadlock. It would also trigger the same type of deadlock in the unmount path. Possibly, it could also introduce some other locking dependencies that lockdep would report. To fix this call try_to_writeback_inodes_sb() instead of writeback_inodes_sb(), because that will try to read lock sb->s_umount and then will only call writeback_inodes_sb() if it was able to lock it. This is fine because the cases where it can't read lock sb->s_umount are during a filesystem unmount or during a filesystem freeze - in those cases sb->s_umount is write locked and sync_filesystem() is called, which calls writeback_inodes_sb(). In other words, in all cases where we can't take a read lock on sb->s_umount, writeback is already being triggered elsewhere. An alternative would be to call btrfs_start_delalloc_roots() with a number of pages different from LONG_MAX, for example matching the number of delalloc bytes we currently have, in which case we would end up starting all delalloc with filemap_fdatawrite_wbc() and not with an async flush via filemap_flush() - that is only possible after the rather recent commit e076ab2a2ca70a ("btrfs: shrink delalloc pages instead of full inodes"). However that creates a whole new can of worms due to new lock dependencies, which lockdep complains, like for example: [ 8948.247280] ====================================================== [ 8948.247823] WARNING: possible circular locking dependency detected [ 8948.248353] 5.17.0-rc1-btrfs-next-111 #1 Not tainted [ 8948.248786] ------------------------------------------------------ [ 8948.249320] kworker/u16:18/933570 is trying to acquire lock: [ 8948.249812] ffff9b3de1591690 (sb_internal#2){.+.+}-{0:0}, at: find_free_extent+0x141e/0x1590 [btrfs] [ 8948.250638] but task is already holding lock: [ 8948.251140] ffff9b3e09c717d8 (&root->delalloc_mutex){+.+.}-{3:3}, at: start_delalloc_inodes+0x78/0x400 [btrfs] [ 8948.252018] which lock already depends on the new lock.

So just adopt the simple approach of calling try_to_writeback_inodes_sb() at btrfs_start_delalloc_flush().

[PATCH] Drivers: hv: vmbus: Leak pages if set_memory_encrypted() fails

by libo.chen.cn＠windriver.com

From: Rick Edgecombe <rick.p.edgecombe(a)intel.com> commit 03f5a999adba ("Drivers: hv: vmbus: Leak pages if set_memory_encrypted() fails") In CoCo VMs it is possible for the untrusted host to cause set_memory_encrypted() or set_memory_decrypted() to fail such that an error is returned and the resulting memory is shared. Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page allocator, which could lead to functional or security issues. VMBus code could free decrypted pages if set_memory_encrypted()/decrypted() fails. Leak the pages if this happens.

[PATCH] x86/stackprotector: Work around strict Clang TLS symbol requirements

by Ard Biesheuvel

From: Ard Biesheuvel <ardb(a)kernel.org> GCC and Clang both implement stack protector support based on Thread Local Storage (TLS) variables, and this is used in the kernel to implement per-task stack cookies, by copying a task's stack cookie into a per-CPU variable every time it is scheduled in. Both now also implement -mstack-protector-guard-symbol=, which permits the TLS variable to be specified directly. This is useful because it will allow us to move away from using a fixed offset of 40 bytes into the per-CPU area on x86_64, which requires a lot of special handling in the per-CPU code and the runtime relocation code. However, while GCC is rather lax in its implementation of this command line option, Clang actually requires that the provided symbol name refers to a TLS variable (i.e., one declared with __thread), although it also permits the variable to be undeclared entirely, in which case it will use an implicit declaration of the right type. The upshot of this is that Clang will emit the correct references to the stack cookie variable in most cases, e.g., 10d: 64 a1 00 00 00 00 mov %fs:0x0,%eax 10f: R_386_32 __stack_chk_guard However, if a non-TLS definition of the symbol in question is visible in the same compilation unit (which amounts to the whole of vmlinux if LTO is enabled), it will drop the per-CPU prefix and emit a load from a bogus address. Work around this by using a symbol name that never occurs in C code, and emit it as an alias in the linker script.

[PATCH v2 0/6] sysctl: prepare sysctl core for const struct ctl_table

by Thomas Weißschuh

Adapt the internal and external APIs of the sysctl core to handle read-only instances of "struct ctl_table". Patch 1: Bugfix for the sysctl core, the bug can be reliably triggered with the series applied Patch 2: Trivial preparation commit for the sysctl BPF hook Patch 3: Adapts the internal sysctl APIs Patch 4: Adapts the external sysctl APIs Patch 5: Constifies the sysctl internal tables as proof that it works Patch 6: Updates scripts/const_structs.checkpatch for "struct ctl_table" Motivation ========== Moving structures containing function pointers into unmodifiable .rodata prevents attackers or bugs from corrupting and diverting those pointers. Also the "struct ctl_table" exposed by the sysctl core were never meant to be mutated by users. For this goal changes to both the sysctl core and "const" qualifiers for various sysctl APIs are necessary. Full Process ============ * Drop ctl_table modifications from the sysctl core ([0], in mainline) * Constify arguments to ctl_table_root::{set_ownership,permissions} ([1], in mainline) * Migrate users of "ctl_table_header::ctl_table_arg" to "const". (in mainline) * Afterwards convert "ctl_table_header::ctl_table_arg" itself to const. (in mainline) * Prepare helpers used to implement proc_handlers throughout the tree to use "const struct ctl_table *". ([2], in mainline) * Afterwards switch over all proc_handlers callbacks to use "const struct ctl_table *" in one commit. (in mainline) * Switch over the internals of the sysctl core to "const struct ctl_table *" (this series) * Switch include/linux/sysctl.h to "const struct ctl_table *" (this series) * Transition instances of "struct ctl_table" through the tree to const (to be done) This series is meant to be applied through the sysctl tree.

[PATCH] usb: dwc3: core: Fix system suspend on TI AM62 platforms

by Roger Quadros

Since commit 6d735722063a ("usb: dwc3: core: Prevent phy suspend during init"), system suspend is broken on AM62 TI platforms. Before that commit, both DWC3_GUSB3PIPECTL_SUSPHY and DWC3_GUSB2PHYCFG_SUSPHY bits (hence forth called 2 SUSPHY bits) were being set during core initialization and even during core re-initialization after a system suspend/resume. These bits are required to be set for system suspend/resume to work correctly on AM62 platforms. Since that commit, the 2 SUSPHY bits are not set for DEVICE/OTG mode if gadget driver is not loaded and started. For Host mode, the 2 SUSPHY bits are set before the first system suspend but get cleared at system resume during core re-init and are never set again. This patch resovles these two issues by ensuring the 2 SUSPHY bits are set before system suspend and restored to the original state during system resume.

[PATCH v5 5/7] clk: qcom: gcc-x1e80100: Fix halt_check for pipediv2 clocks

by Qiang Yu

The pipediv2_clk's source from the same mux as pipe clock. So they have same limitation, which is that the PHY sequence requires to enable these local CBCs before the PHY is actually outputting a clock to them. This means the clock won't actually turn on when we vote them. Hence, let's skip the halt bit check of the pipediv2_clk, otherwise pipediv2_clk may stuck at off state during bootup.

This is because segment registers with an arbitrary user value can result in #GP when executing VERW. Intel SDM vol. 2C documents the following behavior for VERW instruction: #GP(0) - If a memory operand effective address is outside the CS, DS, ES, FS, or GS segment limit. CLEAR_CPU_BUFFERS macro executes VERW instruction before returning to user space. Use %cs selector to reference VERW operand. This ensures VERW will not #GP for an arbitrary user %ds.

[PATCH] media: i2c: tc358743: Fix crash in the probe error path when using polling

If an error occurs in the probe() function, we should remove the polling timer that was alarmed earlier, otherwise the timer is called with arguments that are already freed, which results in a crash. ------------[ cut here ]------------ WARNING: CPU: 3 PID: 0 at kernel/time/timer.c:1830 __run_timers+0x244/0x268 Modules linked in: CPU: 3 UID: 0 PID: 0 Comm: swapper/3 Not tainted 6.11.0 #226 Hardware name: Diasom DS-RK3568-SOM-EVB (DT) pstate: 804000c9 (Nzcv daIF +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : __run_timers+0x244/0x268 lr : __run_timers+0x1d4/0x268 sp : ffffff80eff2baf0 x29: ffffff80eff2bb50 x28: 7fffffffffffffff x27: ffffff80eff2bb00 x26: ffffffc080f669c0 x25: ffffff80efef6bf0 x24: ffffff80eff2bb00 x23: 0000000000000000 x22: dead000000000122 x21: 0000000000000000 x20: ffffff80efef6b80 x19: ffffff80041c8bf8 x18: ffffffffffffffff x17: ffffffc06f146000 x16: ffffff80eff27dc0 x15: 000000000000003e x14: 0000000000000000 x13: 00000000000054da x12: 0000000000000000 x11: 00000000000639c0 x10: 000000000000000c x9 : 0000000000000009 x8 : ffffff80eff2cb40 x7 : ffffff80eff2cb40 x6 : ffffff8002bee480 x5 : ffffffc080cb2220 x4 : ffffffc080cb2150 x3 : 00000000000f4240 x2 : 0000000000000102 x1 : ffffff80eff2bb00 x0 : ffffff80041c8bf0 Call trace: __run_timers+0x244/0x268 timer_expire_remote+0x50/0x68 tmigr_handle_remote+0x388/0x39c run_timer_softirq+0x38/0x44 handle_softirqs+0x138/0x298 __do_softirq+0x14/0x20 ____do_softirq+0x10/0x1c call_on_irq_stack+0x24/0x4c do_softirq_own_stack+0x1c/0x2c irq_exit_rcu+0x9c/0xcc el1_interrupt+0x48/0xc0 el1h_64_irq_handler+0x18/0x24 el1h_64_irq+0x7c/0x80 default_idle_call+0x34/0x68 do_idle+0x23c/0x294 cpu_startup_entry+0x38/0x3c secondary_start_kernel+0x128/0x160 __secondary_switched+0xb8/0xbc ---[ end trace 0000000000000000 ]--- Fixes: 4e66a52a2e4c ("[media] tc358743: Add support for platforms without IRQ line") Signed-off-by: Alexander Shiyan <eagle.alexander923(a)gmail.com> Cc: stable(a)vger.kernel.org --- drivers/media/i2c/tc358743.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/drivers/media/i2c/tc358743.c b/drivers/media/i2c/tc358743.c index 65d58ddf0287..344a670e732f 100644 --- a/drivers/media/i2c/tc358743.c +++ b/drivers/media/i2c/tc358743.c @@ -2168,8 +2168,10 @@ static int tc358743_probe(struct i2c_client *client) err_work_queues: cec_unregister_adapter(state->cec_adap); - if (!state->i2c_client->irq) + if (!state->i2c_client->irq) { + del_timer(&state->timer); flush_work(&state->work_i2c_poll); + } cancel_delayed_work(&state->delayed_work_enable_hotplug); mutex_destroy(&state->confctl_mutex); err_hdl: -- 2.39.1

[PATCH 4.19.y] Input: synaptics-rmi4 - fix UAF of IRQ domain on driver removal

by Tzung-Bi Shih

From: Mathias Krause <minipli(a)grsecurity.net> commit fbf8d71742557abaf558d8efb96742d442720cc2 upstream. Calling irq_domain_remove() will lead to freeing the IRQ domain prematurely. The domain is still referenced and will be attempted to get used via rmi_free_function_list() -> rmi_unregister_function() -> irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer. With PaX's MEMORY_SANITIZE this will lead to an access fault when attempting to dereference embedded pointers, as in Torsten's report that was faulting on the 'domain->ops->unmap' test. Fix this by releasing the IRQ domain only after all related IRQs have been deactivated.

[PATCH] USB: chaoskey: fail open after removal

by Oliver Neukum

chaoskey_open() takes the lock only to increase the counter of openings. That means that the mutual exclusion with chaoskey_disconnect() cannot prevent an increase of the counter and chaoskey_open() returning a success. If that race is hit, chaoskey_disconnect() will happily free all resources associated with the device after it has dropped the lock, as it has read the counter as zero. To prevent this race chaoskey_open() has to check the presence of the device under the lock. However, the current per device lock cannot be used, because it is a part of the data structure to be freed. Hence an additional global mutex is needed. The issue is as old as the driver.

[PATCH 6.6.y] Input: synaptics-rmi4 - fix UAF of IRQ domain on driver removal

by Tzung-Bi Shih

From: Mathias Krause <minipli(a)grsecurity.net> commit fbf8d71742557abaf558d8efb96742d442720cc2 upstream. Calling irq_domain_remove() will lead to freeing the IRQ domain prematurely. The domain is still referenced and will be attempted to get used via rmi_free_function_list() -> rmi_unregister_function() -> irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer. With PaX's MEMORY_SANITIZE this will lead to an access fault when attempting to dereference embedded pointers, as in Torsten's report that was faulting on the 'domain->ops->unmap' test. Fix this by releasing the IRQ domain only after all related IRQs have been deactivated.

[PATCH] sched: psi: fix bogus pressure spikes from aggregation race

by Yo-Jung (Leo) Lin

From: Johannes Weiner <hannes(a)cmpxchg.org> Brandon reports sporadic, non-sensical spikes in cumulative pressure time (total=) when reading cpu.pressure at a high rate. This is due to a race condition between reader aggregation and tasks changing states. While it affects all states and all resources captured by PSI, in practice it most likely triggers with CPU pressure, since scheduling events are so frequent compared to other resource events. The race context is the live snooping of ongoing stalls during a pressure read. The read aggregates per-cpu records for stalls that have concluded, but will also incorporate ad-hoc the duration of any active state that hasn't been recorded yet. This is important to get timely measurements of ongoing stalls. Those ad-hoc samples are calculated on-the-fly up to the current time on that CPU; since the stall hasn't concluded, it's expected that this is the minimum amount of stall time that will enter the per-cpu records once it does. The problem is that the path that concludes the state uses a CPU clock read that is not synchronized against aggregators; the clock is read outside of the seqlock protection. This allows aggregators to race and snoop a stall with a longer duration than will actually be recorded. With the recorded stall time being less than the last snapshot remembered by the aggregator, a subsequent sample will underflow and observe a bogus delta value, resulting in an erratic jump in pressure. Fix this by moving the clock read of the state change into the seqlock protection. This ensures no aggregation can snoop live stalls past the time that's recorded when the state concludes.

[PATCH] usb: dwc3: Wait for EndXfer completion before restoring GUSB2PHYCFG

by Prashanth K

DWC3 programming guide mentions that when operating in USB2.0 speeds, if GUSB2PHYCFG[6] or GUSB2PHYCFG[8] is set, it must be cleared prior to issuing commands and may be set again after the command completes. But currently while issuing EndXfer command without CmdIOC set, we wait for 1ms after GUSB2PHYCFG is restored. This results in cases where EndXfer command doesn't get completed and causes SMMU faults since requests are unmapped afterwards. Hence restore GUSB2PHYCFG after waiting for EndXfer command completion.

[PATCH] iwlegacy: Clear stale interrupts before enabling interrupts

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> iwl4965 fails upon resume from hibernation on my laptop. The reason seems to be a stale interrupt which isn't being cleared out before interrupts are enabled. We end up with a race beween the resume trying to bring things back up, and the restart work (queued form the interrupt handler) trying to bring things down. Eventually the whole thing blows up. Fix the problem by clearing out any stale interrupts before interrupts get enabled. Here's a debug log of the indicent: [ 12.042589] ieee80211 phy0: il_isr ISR inta 0x00000080, enabled 0xaa00008b, fh 0x00000000 [ 12.042625] ieee80211 phy0: il4965_irq_tasklet inta 0x00000080, enabled 0x00000000, fh 0x00000000 [ 12.042651] iwl4965 0000:10:00.0: RF_KILL bit toggled to enable radio.

Dell WD19TB Thunderbolt Dock not working with kernel > 6.6.28-1

by Fabian Stäber

Hi, I got a Dell WD19TBS Thunderbolt Dock, and it has been working with Linux for years without issues. However, updating to linux-lts-6.6.29-1 or newer breaks the USB ports on my Dock. Using the latest non-LTS kernel doesn't help, it also breaks the USB ports. Downgrading the kernel to linux-lts-6.6.28-1 works. This is the last working version. I opened a thread on the Arch Linux forum https://bbs.archlinux.org/viewtopic.php?id=299604 with some dmesg output. However, it sounds like this is a regression in the Linux kernel, so I'm posting this here as well. Let me know if you need any more info. Thanks a lot Fabian

[tip: irq/urgent] irqchip/gic-v4: Don't allow a VMOVP on a dying VPE

by tip-bot2 for Marc Zyngier

The following commit has been merged into the irq/urgent branch of tip: Commit-ID: 1442ee0011983f0c5c4b92380e6853afb513841a Gitweb: https://git.kernel.org/tip/1442ee0011983f0c5c4b92380e6853afb513841a Author: Marc Zyngier <maz(a)kernel.org> AuthorDate: Wed, 02 Oct 2024 21:49:59 +01:00 Committer: Thomas Gleixner <tglx(a)linutronix.de> CommitterDate: Tue, 08 Oct 2024 17:44:27 +02:00 irqchip/gic-v4: Don't allow a VMOVP on a dying VPE Kunkun Jiang reported that there is a small window of opportunity for userspace to force a change of affinity for a VPE while the VPE has already been unmapped, but the corresponding doorbell interrupt still visible in /proc/irq/.

[PATCH v2] irqchip/sifive-plic: Unmask interrupt in plic_irq_enable()

by Nam Cao

It is possible that an interrupt is disabled and masked at the same time. When the interrupt is enabled again by enable_irq(), only plic_irq_enable() is called, not plic_irq_unmask(). The interrupt remains masked and never raises. An example where interrupt is both disabled and masked is when handle_fasteoi_irq() is the handler, and IRQS_ONESHOT is set. The interrupt handler: 1. Mask the interrupt 2. Handle the interrupt 3. Check if interrupt is still enabled, and unmask it (see cond_unmask_eoi_irq()) If another task disables the interrupt in the middle of the above steps, the interrupt will not get unmasked, and will remain masked when it is enabled in the future. The problem is occasionally observed when PREEMPT_RT is enabled, because PREEMPT_RT add the IRQS_ONESHOT flag. But PREEMPT_RT only makes the problem more likely to appear, the bug has been around since commit a1706a1c5062 ("irqchip/sifive-plic: Separate the enable and mask operations"). Fix it by unmasking interrupt in plic_irq_enable().

This bug is only reachable if either CONFIG_READ_ONLY_THP_FOR_FS is set or THP shmem is usable. (Unprivileged namespaces can be used to set up a tmpfs that can contain THP shmem pages with "huge=advise".) If userspace triggers this bug *in multiple processes*, this could likely be used to create stale TLB entries pointing to freed pages or cause kernel UAF by breaking an invariant the rmap code relies on. Fix it by moving the rmap locking up so that it covers the span from reading the PMD entry to moving the page table.

[PATCH 00/15] media: stm32: introduction of CSI / DCMIPP for STM32MP25

by Alain Volmat

This series introduces the camera pipeline support for the STM32MP25 SOC. The STM32MP25 has 3 pipelines, fed from a single camera input which can be either parallel or csi. This series adds the basic support for the 1st pipe (dump) which, in term of features is same as the one featured on the STM32MP13 SOC. It focuses on introduction of the CSI input stage for the DCMIPP, and the CSI specific new control code for the DCMIPP. One of the subdev of the DCMIPP, dcmipp_parallel is now renamed as dcmipp_input since it allows to not only control the parallel but also the csi interface.

[PATCH] vdpa: solidrun: Fix UB bug with devres

by Philipp Stanner

In psnet_open_pf_bar() and snet_open_vf_bar() a string later passed to pcim_iomap_regions() is placed on the stack. Neither pcim_iomap_regions() nor the functions it calls copy that string.

[PATCH] [PATCH v3] perf/x86/amd: check event before enable to avoid GPF

by George Kennedy

On AMD machines cpuc->events[idx] can become NULL in a subtle race condition with NMI->throttle->x86_pmu_stop(). Check event for NULL in amd_pmu_enable_all() before enable to avoid a GPF. This appears to be an AMD only issue. Syzkaller reported a GPF in amd_pmu_enable_all.

[PATCH RFC 6.6.y 00/15] Some missing CVE fixes

by Vegard Nossum

Hi, We noticed some cases where a mainline commit that fixes a CVE has a Fixes: tag pointing to a commit that has been backported to 6.6 but where the fix is not present. Harshit and I have backported some of these patches. We are not subsystem experts and that's why we have marked this series as RFC -- any review or feedback is welcome. We've tried to document the conflicts and their causes in the changelogs. We haven't done targeted testing beyond our usual stable tests, but this includes for example the netfilter test suite, which did not show any new failures. Greg: feel free to take these patches or leave it as you want. Conflict resolution always comes with the risk of missing something and we want to be up-front about that. On the other hand, these were identified as CVE fixes so presumably we're not the only ones who want them. [Note: we added some other people to Cc that we think would be interested, let me know privately if you don't want to receive emails like these in the future.] Thanks, Vegard --- Benjamin Gaignard (1): media: usbtv: Remove useless locks in usbtv_video_free() Chen Yu (1): efi/unaccepted: touch soft lockup during memory accept Christophe JAILLET (1): null_blk: Remove usage of the deprecated ida_simple_xx() API Luiz Augusto von Dentz (3): Bluetooth: hci_sock: Fix not validating setsockopt user input Bluetooth: ISO: Fix not validating setsockopt user input Bluetooth: L2CAP: Fix not validating setsockopt user input Mads Bligaard Nielsen (1): drm/bridge: adv7511: fix crash on irq during probe Mark Pearson (1): platform/x86: think-lmi: Fix password opcode ordering for workstations Nicolin Chen (1): iommufd: Fix protection fault in iommufd_test_syz_conv_iova Pablo Neira Ayuso (2): netfilter: nf_tables: fix memleak in map from abort path netfilter: nf_tables: restore set elements when delete set fails Vladimir Oltean (1): net: dsa: fix netdev_priv() dereference before check on non-DSA netdevice events Xiaolei Wang (1): net: stmmac: move the EST lock to struct stmmac_priv Yu Kuai (1): null_blk: fix null-ptr-dereference while configuring 'power' and 'submit_queues' Zhihao Cheng (1): ubifs: ubifs_symlink: Fix memleak of inode->i_link in error path drivers/block/null_blk/main.c | 44 ++++++++------ drivers/firmware/efi/unaccepted_memory.c | 4 ++ drivers/gpu/drm/bridge/adv7511/adv7511_drv.c | 22 +++---- drivers/iommu/iommufd/selftest.c | 27 +++++++-- drivers/media/usb/usbtv/usbtv-video.c | 7 --- drivers/net/ethernet/stmicro/stmmac/stmmac.h | 2 + .../net/ethernet/stmicro/stmmac/stmmac_ptp.c | 8 +-- .../net/ethernet/stmicro/stmmac/stmmac_tc.c | 18 +++--- drivers/platform/x86/think-lmi.c | 16 +++--- fs/ubifs/dir.c | 2 + include/linux/stmmac.h | 1 - net/bluetooth/hci_sock.c | 21 +++---- net/bluetooth/iso.c | 36 ++++-------- net/bluetooth/l2cap_sock.c | 52 +++++++---------- net/dsa/slave.c | 7 ++- net/netfilter/nf_tables_api.c | 57 +++++++++++++++++-- net/netfilter/nft_set_bitmap.c | 4 +- net/netfilter/nft_set_hash.c | 8 +-- net/netfilter/nft_set_pipapo.c | 5 +- net/netfilter/nft_set_rbtree.c | 4 +- 20 files changed, 192 insertions(+), 153 deletions(-) -- 2.34.1

[PATCH for 6.12] ASoC: SOF: Intel: hda-loader: do not wait for HDaudio IOC

by Peter Ujfalusi

From: Kai Vehmanen <kai.vehmanen(a)linux.intel.com> Commit 9ee3f0d8c999 ("ASOC: SOF: Intel: hda-loader: only wait for HDaudio IOC for IPC4 devices") removed DMA wait for IPC3 case. Proceed and remove the wait for IPC4 devices as well. There is no dependency to IPC version in the load logic and checking the firmware status is a sufficient check in case of errors. The removed code also had a bug in that -ETIMEDOUT is returned without stopping the DMA transfer.

[PATCH v4 0/2] drm/nouveau/dmem: Fix Vulnerability and Device Channels configuration

by Yonatan Maman

From: Yonatan Maman <Ymaman(a)Nvidia.com> This patch series addresses two critical issues in the Nouveau driver related to device channels, error handling, and sensitive data leaks. - Vulnerability in migrate_to_ram: The migrate_to_ram function might return a dirty HIGH_USER page when a copy push command (FW channel) fails, potentially exposing sensitive data and posing a security risk. To mitigate this, the patch ensures the allocation of a non-dirty (zero) page for the destination, preventing the return of a dirty page and enhancing driver security in case of failure. - Privileged Error in Copy Engine Channel: An error was observed when the nouveau_dmem_copy_one function is executed, leading to a Host Copy Engine Privileged error on channel 1. The patch resolves this by adjusting the Copy Engine channel configuration to permit privileged push commands, resolving the error.

[PATCH] fcntl: make F_DUPFD_QUERY associative

by Christian Brauner

Currently when passing a closed file descriptor to fcntl(fd, F_DUPFD_QUERY, fd_dup) the order matters: fd = open("/dev/null"); fd_dup = dup(fd); When we now close one of the file descriptors we get: (1) fcntl(fd, fd_dup) // -EBADF (2) fcntl(fd_dup, fd) // 0 aka not equal depending on which file descriptor is passed first. That's not a huge deal but it gives the api I slightly weird feel. Make it so that the order doesn't matter by requiring that both file descriptors are valid: (1') fcntl(fd, fd_dup) // -EBADF (2') fcntl(fd_dup, fd) // -EBADF Fixes: c62b758bae6a ("fcntl: add F_DUPFD_QUERY fcntl()") Cc: <stable(a)vger.kernel.org> Reported-by: Lennart Poettering <lennart(a)poettering.net> Signed-off-by: Christian Brauner <brauner(a)kernel.org> --- fs/fcntl.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/fs/fcntl.c b/fs/fcntl.c index 22dd9dcce7ec..3d89de31066a 100644 --- a/fs/fcntl.c +++ b/fs/fcntl.c @@ -397,6 +397,9 @@ static long f_dupfd_query(int fd, struct file *filp) { CLASS(fd_raw, f)(fd); + if (fd_empty(f)) + return -EBADF; + /* * We can do the 'fdput()' immediately, as the only thing that * matters is the pointer value which isn't changed by the fdput. -- 2.45.2

This change was made by commit ce8ea7cc6eb313 ("btrfs: don't call btrfs_start_delalloc_roots in flushoncommit"). After that change we started producing that warning, and every now and then a user reports this since the warning happens too often, it spams dmesg/syslog, and a user is unsure if this reflects any problem that might compromise the filesystem's reliability. We can not just lock the sb->s_umount semaphore before calling writeback_inodes_sb(), because that would at least deadlock with filesystem freezing, since at fs/super.c:freeze_super() sync_filesystem() is called while we are holding that semaphore in write mode, and that can trigger a transaction commit, resulting in a deadlock. It would also trigger the same type of deadlock in the unmount path. Possibly, it could also introduce some other locking dependencies that lockdep would report. To fix this call try_to_writeback_inodes_sb() instead of writeback_inodes_sb(), because that will try to read lock sb->s_umount and then will only call writeback_inodes_sb() if it was able to lock it. This is fine because the cases where it can't read lock sb->s_umount are during a filesystem unmount or during a filesystem freeze - in those cases sb->s_umount is write locked and sync_filesystem() is called, which calls writeback_inodes_sb(). In other words, in all cases where we can't take a read lock on sb->s_umount, writeback is already being triggered elsewhere. An alternative would be to call btrfs_start_delalloc_roots() with a number of pages different from LONG_MAX, for example matching the number of delalloc bytes we currently have, in which case we would end up starting all delalloc with filemap_fdatawrite_wbc() and not with an async flush via filemap_flush() - that is only possible after the rather recent commit e076ab2a2ca70a ("btrfs: shrink delalloc pages instead of full inodes"). However that creates a whole new can of worms due to new lock dependencies, which lockdep complains, like for example: [ 8948.247280] ====================================================== [ 8948.247823] WARNING: possible circular locking dependency detected [ 8948.248353] 5.17.0-rc1-btrfs-next-111 #1 Not tainted [ 8948.248786] ------------------------------------------------------ [ 8948.249320] kworker/u16:18/933570 is trying to acquire lock: [ 8948.249812] ffff9b3de1591690 (sb_internal#2){.+.+}-{0:0}, at: find_free_extent+0x141e/0x1590 [btrfs] [ 8948.250638] but task is already holding lock: [ 8948.251140] ffff9b3e09c717d8 (&root->delalloc_mutex){+.+.}-{3:3}, at: start_delalloc_inodes+0x78/0x400 [btrfs] [ 8948.252018] which lock already depends on the new lock.

[PATCH] arm64: dts: mediatek: mt8186-corsola-voltorb: Merge speaker codec nodes

by Chen-Yu Tsai

The Voltorb device uses a speaker codec different from the original Corsola device. When the Voltorb device tree was first added, the new codec was added as a separate node when it should have just replaced the existing one. Merge the two nodes. The only differences are the compatible string and the GPIO line property name. This keeps the device node path for the speaker codec the same across the MT8186 Chromebook line.

Alex reports that syzkaller has managed to trigger a use-after-free when tearing down a VM: BUG: KASAN: slab-use-after-free in kvm_put_kvm+0x300/0xe68 virt/kvm/kvm_main.c:5769 Read of size 8 at addr ffffff801c6890d0 by task syz.3.2219/10758 CPU: 3 UID: 0 PID: 10758 Comm: syz.3.2219 Not tainted 6.11.0-rc6-dirty #64 Hardware name: linux,dummy-virt (DT) Call trace: dump_backtrace+0x17c/0x1a8 arch/arm64/kernel/stacktrace.c:317 show_stack+0x2c/0x3c arch/arm64/kernel/stacktrace.c:324 __dump_stack lib/dump_stack.c:93 [inline] dump_stack_lvl+0x94/0xc0 lib/dump_stack.c:119 print_report+0x144/0x7a4 mm/kasan/report.c:377 kasan_report+0xcc/0x128 mm/kasan/report.c:601 __asan_report_load8_noabort+0x20/0x2c mm/kasan/report_generic.c:381 kvm_put_kvm+0x300/0xe68 virt/kvm/kvm_main.c:5769 kvm_vm_release+0x4c/0x60 virt/kvm/kvm_main.c:1409 __fput+0x198/0x71c fs/file_table.c:422 ____fput+0x20/0x30 fs/file_table.c:450 task_work_run+0x1cc/0x23c kernel/task_work.c:228 do_notify_resume+0x144/0x1a0 include/linux/resume_user_mode.h:50 el0_svc+0x64/0x68 arch/arm64/kernel/entry-common.c:169 el0t_64_sync_handler+0x90/0xfc arch/arm64/kernel/entry-common.c:730 el0t_64_sync+0x190/0x194 arch/arm64/kernel/entry.S:598 Upon closer inspection, it appears that we do not properly tear down the MMIO registration for a vCPU that fails creation late in the game, e.g. a vCPU w/ the same ID already exists in the VM. It is important to consider the context of commit that introduced this bug by moving the unregistration out of __kvm_vgic_vcpu_destroy(). That change correctly sought to avoid an srcu v. config_lock inversion by breaking up the vCPU teardown into two parts, one guarded by the config_lock. Fix the use-after-free while avoiding lock inversion by adding a special-cased unregistration to __kvm_vgic_vcpu_destroy(). This is safe because failed vCPUs are torn down outside of the config_lock.

[PATCH] HID: plantronics: Workaround for an unexcepted opposite volume key

by Wade Wang

Some Plantronics headset as the below send an unexcept opposite volume key's HID report for each volume key press after 200ms, like unecepted Volume Up Key following Volume Down key pressed by user. This patch adds a quirk to hid-plantronics for these devices, which will ignore the second unexcepted opposite volume key if it happens within 220ms from the last one that was handled. Plantronics EncorePro 500 Series (047f:431e) Plantronics Blackwire_3325 Series (047f:430c) The patch was tested on the mentioned model, it shouldn't affect other models, however, this quirk might be needed for them too. Auto-repeat (when a key is held pressed) is not affected per test result.

Regression in 6.11.2

by Mario Limonciello

Hi, commit 872b8f14d772 ("drm/amd/display: Validate backlight caps are sane") was added to stable trees to fix a brightness problem on one laptop on a buggy firmware but with how aggressive it was it caused a problem on another. Fortunately the problem on the other was already fixed in 6.12 though! commit 87d749a6aab7 ("drm/amd/display: Allow backlight to go below `AMDGPU_DM_DEFAULT_MIN_BACKLIGHT`") Can that commit please be brought everywhere that 872b8f14d772 went? Thanks!

The only disadvantage of zsmalloc in comparison is the dependency on MMU, and zbud is a more common option for !MMU as it was the default zswap allocator for a long time. Historically, zsmalloc had worse latency than zbud and z3fold but offered better memory savings. This is no longer the case as shown by a simple recent analysis [1]. That analysis showed that z3fold does not have any advantage over zsmalloc or zbud considering both performance and memory usage. In a kernel build test on tmpfs in a limited cgroup, z3fold took 3% more time and used 1.8% more memory. The latency of zswap_load() was 7% higher, and that of zswap_store() was 10% higher. Zsmalloc is better in all metrics. Moreover, z3fold apparently has latent bugs, which was made noticeable by a recent soft lockup bug report with z3fold [2]. Switching to zsmalloc not only fixed the problem, but also reduced the swap usage from 6~8G to 1~2G. Other users have also reported being bitten by mistakenly enabling z3fold. Other than hurting users, z3fold is repeatedly causing wasted engineering effort. Apart from investigating the above bug, it came up in multiple development discussions (e.g. [3]) as something we need to handle, when there aren't any legit users (at least not intentionally). The natural course of action is to deprecate z3fold, and remove in a few cycles if no objections are raised from active users. Next on the list should be zbud, as it offers marginal latency gains at the cost of huge memory waste when compared to zsmalloc. That one will need to wait until zsmalloc does not depend on MMU. Rename the user-visible config option from CONFIG_Z3FOLD to CONFIG_Z3FOLD_DEPRECATED so that users with CONFIG_Z3FOLD=y get a new prompt with explanation during make oldconfig. Also, remove CONFIG_Z3FOLD=y from defconfigs.

Approximately, a series of changes to this code by the three commits cited below resulted in subtle resource cleanup to be missed. The main culprit is the change in error handling in 2d31604 which meant that a failure in init_request would no longer cause cleanup to be called. That would prevent the ceph_put_cap_refs which would cleanup the leaked cap ref.

[PATCH] mm: remove the newlines, which are added for unknown reasons and interfere with bug analysis

by Jeongjun Park

Looking at the source code links for mm/memory.c in the sample reports in the syzbot report links [1]. it looks like the line numbers are designated as lines that have been increased by 1. This may seem like a problem with syzkaller or the addr2line program that assigns the line numbers, but there is no problem with either of them. In the previous commit d61ea1cb0095 ("userfaultfd: UFFD_FEATURE_WP_ASYNC"), when modifying mm/memory.c, an unknown line break is added to the very first line of the file. However, the git.kernel.org site displays the source code with the added line break removed, so even though addr2line has assigned the correct line number, it looks like the line number has increased by 1. This may seem like a trivial thing, but I think it would be appropriate to remove all the newline characters added to the upstream and stable versions, as they are not only incorrect in terms of code style but also hinder bug analysis.

At that point, the mmap_lock is held in write mode, but no rmap locks are held yet. For PMD entries that point to page tables and are fully covered by the source address range, move_pgt_entry(NORMAL_PMD, ...) is called, which first takes rmap locks, then does move_normal_pmd(). move_normal_pmd() takes the necessary page table locks at source and destination, then moves an entire page table from the source to the destination. The problem is: The rmap locks, which protect against concurrent page table removal by retract_page_tables() in the THP code, are only taken after the PMD entry has been read and it has been decided how to move it. So we can race as follows (with two processes that have mappings of the same tmpfs file that is stored on a tmpfs mount with huge=advise); note that process A accesses page tables through the MM while process B does it through the file rmap: process A process B ========= ========= mremap mremap_to move_vma move_page_tables get_old_pmd alloc_new_pmd *** PREEMPT *** madvise(MADV_COLLAPSE) do_madvise madvise_walk_vmas madvise_vma_behavior madvise_collapse hpage_collapse_scan_file collapse_file retract_page_tables i_mmap_lock_read(mapping) pmdp_collapse_flush i_mmap_unlock_read(mapping) move_pgt_entry(NORMAL_PMD, ...) take_rmap_locks move_normal_pmd drop_rmap_locks When this happens, move_normal_pmd() can end up creating bogus PMD entries in the line `pmd_populate(mm, new_pmd, pmd_pgtable(pmd))`. The effect depends on arch-specific and machine-specific details; on x86, you can end up with physical page 0 mapped as a page table, which is likely exploitable for user->kernel privilege escalation. Fix the race by letting process B recheck that the PMD still points to a page table after the rmap locks have been taken. Otherwise, we bail and let the caller fall back to the PTE-level copying path, which will then bail immediately at the pmd_none() check. Bug reachability: Reaching this bug requires that you can create shmem/file THP mappings - anonymous THP uses different code that doesn't zap stuff under rmap locks. File THP is gated on an experimental config flag (CONFIG_READ_ONLY_THP_FOR_FS), so on normal distro kernels you need shmem THP to hit this bug. As far as I know, getting shmem THP normally requires that you can mount your own tmpfs with the right mount flags, which would require creating your own user+mount namespace; though I don't know if some distros maybe enable shmem THP by default or something like that. Bug impact: This issue can likely be used for user->kernel privilege escalation when it is reachable.

[to-be-updated] mm-mremap-prevent-racing-change-of-old-pmd-type.patch removed from -mm tree

by Andrew Morton

The quilt patch titled Subject: mm/mremap: prevent racing change of old pmd type has been removed from the -mm tree. Its filename was mm-mremap-prevent-racing-change-of-old-pmd-type.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Jann Horn <jannh(a)google.com> Subject: mm/mremap: prevent racing change of old pmd type Date: Wed, 02 Oct 2024 23:07:06 +0200 Prevent move_normal_pmd() in mremap() from racing with retract_page_tables() in MADVISE_COLLAPSE such that pmd_populate(mm, new_pmd, pmd_pgtable(pmd)) operates on an empty source pmd, causing creation of a new pmd which maps physical address 0 as a page table. This bug is only reachable if either CONFIG_READ_ONLY_THP_FOR_FS is set or THP shmem is usable. (Unprivileged namespaces can be used to set up a tmpfs that can contain THP shmem pages with "huge=advise".) If userspace triggers this bug *in multiple processes*, this could likely be used to create stale TLB entries pointing to freed pages or cause kernel UAF by breaking an invariant the rmap code relies on. Fix it by moving the rmap locking up so that it covers the span from reading the PMD entry to moving the page table.

[net PATCH v2] net: phy: Remove LED entry from LEDs list on unregister

by Christian Marangi

Commit c938ab4da0eb ("net: phy: Manual remove LEDs to ensure correct ordering") correctly fixed a problem with using devm_ but missed removing the LED entry from the LEDs list. This cause kernel panic on specific scenario where the port for the PHY is torn down and up and the kmod for the PHY is removed. On setting the port down the first time, the assosiacted LEDs are correctly unregistered. The associated kmod for the PHY is now removed. The kmod is now added again and the port is now put up, the associated LED are registered again. On putting the port down again for the second time after these step, the LED list now have 4 elements. With the first 2 already unregistered previously and the 2 new one registered again. This cause a kernel panic as the first 2 element should have been removed. Fix this by correctly removing the element when LED is unregistered.

Its filename is mm-enforce-a-minimal-stack-gap-even-against-inaccessible-vmas.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: Jann Horn <jannh(a)google.com> Subject: mm: enforce a minimal stack gap even against inaccessible VMAs Date: Tue, 08 Oct 2024 00:55:39 +0200 As explained in the comment block this change adds, we can't tell what userspace's intent is when the stack grows towards an inaccessible VMA. I have a (highly contrived) C testcase for 32-bit x86 userspace with glibc that mixes malloc(), pthread creation, and recursion in just the right way such that the main stack overflows into malloc() arena memory. I don't know of any specific scenario where this is actually exploitable, but it seems like it could be a security problem for sufficiently unlucky userspace. I believe we should ensure that, as long as code is compiled with something like -fstack-check, a stack overflow in it can never cause the main stack to overflow into adjacent heap memory. My fix effectively reverts the behavior for !vma_is_accessible() VMAs to the behavior before commit 1be7107fbe18 ("mm: larger stack guard gap, between vmas"), so I think it should be a fairly safe change even in case A.
