It does not support runtime switching without a full restart. On older firmware, this accidentally worked to some degree due to missing checks, but couldn't be supported properly, because it left the 6 GHz channels uncalibrated. Newer firmware refuses to start on either band if the passed EEPROM data indicates support for both. Deal with this limitation by using a module parameter to specify the preferred band in case both are supported.

Fix the crash by introducing open() and close() methods for the port and check if the port is open before trying to access psmouse instance.

Usually, this is solved by just using the MODULE_DEVICE_TABLE() macro to export all the device IDs as module aliases. But this driver is special due how matches with devices and decides what platform supports. There are two of_device_id lists, an allow list that are for CPU devices that always match and a deny list that's for devices that must not match. The driver registers a cpufreq-dt platform device for all the CPU device nodes that either are in the allow list or contain an operating-points-v2 property and are not in the deny list. Enforce builtin compile of cpufreq-dt-platdev to make autoload work.

The bug reports suggest a refcount underflow on struct page due to a use after free or double free. The bisected commit switches fuse_readahead() to readahead_folio() which includes a folio_put() and removes folio_put() from fuse_readpages_end(). As a result folios on the ap->folios (previously ap->pages) don't have an elevated refcount. According to Matthew the folio lock should protect them from being freed prematurely. It's unclear why not, but before this is fully resolved we can stop the kernels from crashing by having the refcount relevated again. Thus switch to __readahead_folio() that does not drop the refcount, and reinstate folio_put() in fuse_readpages_end().

[PATCH] mm/cma: add an API to enable/disable concurrent memory allocation for the CMA

by yangge1116＠126.com

From: yangge <yangge1116(a)126.com> Commit 60a60e32cf91 ("Revert "mm/cma.c: remove redundant cma_mutex lock"") simply reverts to the original method of using the cma_mutex to ensure that alloc_contig_range() runs sequentially. This change was made to avoid concurrency allocation failures. However, it can negatively impact performance when concurrent allocation of CMA memory is required. To address this issue, we could introduce an API for concurrency settings, allowing users to decide whether their CMA can perform concurrent memory allocations or not.

[PATCH v3 2/5] misc: pci_endpoint_test: Fix disyplaying irq_type after request_irq error

by Kunihiko Hayashi

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

[PATCH v2 1/3] misc: pci_endpoint_test: Avoid issue of interrupts remaining after request_irq error

After devm_request_irq() fails with error, pci_endpoint_test_free_irq_vectors() is called to free allocated vectors with pci_free_irq_vectors(). However some requested IRQs are still allocated, so there are still /proc/irq/* entries remaining and we encounters WARN() with the following message: remove_proc_entry: removing non-empty directory 'irq/30', leaking at least 'pci-endpoint-test.0' WARNING: CPU: 0 PID: 80 at fs/proc/generic.c:717 remove_proc_entry +0x190/0x19c To solve this issue, set the number of remaining IRQs and release the IRQs in advance by calling pci_endpoint_test_release_irq().

The code in mptcp_pm_nl_fullmesh() expects to change it only on 'subflow' endpoints, to recreate more or less subflows using the linked address. Unfortunately, the set_flags() hook was a bit more permissive, and allowed 'implicit' endpoints to get the 'fullmesh' flag while it is not allowed before.

Please Apply: Revert "drm/amd/display: Fix green screen issue after suspend"

by Mingcong Bai

The display on Lenovo Xiaoxin Pro 13 2019 (Lenovo XiaoXinPro-13API 2019) briefly shows a garbled screen upon wakeup from S3 with kernel v6.13.2, but not with v6.14-rc1. I have bisected to 04d6273faed083e619fc39a738ab0372b6a4db20 ("Revert "drm/amd/display: Fix green screen issue after suspend"") as the fix to this issue. However, it is quite strange that the title indicated a revert to the fix for the exact issue I was experiencing - despite the commit claiming that the maintainers "cannot see the issue" any more. It seems that I'm running into some sort of unexpected issue that is outside of AMD's test case. In any case, this commit fixes the issue on the device I have tested and applies cleanly on 6.13. I would therefore like to request for this commit to be backported to 6.13 (and maybe other branches, but I think the maintainers may have a better idea on this).

[PATCH v9 05/13] drm/bridge: cdns-dsi: Wait for Clk and Data Lanes to be ready

by Aradhya Bhatia

From: Aradhya Bhatia <a-bhatia1(a)ti.com> Once the DSI Link and DSI Phy are initialized, the code needs to wait for Clk and Data Lanes to be ready, before continuing configuration. This is in accordance with the DSI Start-up procedure, found in the Technical Reference Manual of Texas Instrument's J721E SoC[0] which houses this DSI TX controller.

[PATCH v9 03/13] drm/bridge: cdns-dsi: Fix the clock variable for mode_valid()

by Aradhya Bhatia

From: Aradhya Bhatia <a-bhatia1(a)ti.com> The crtc_* mode parameters do not get generated (duplicated in this case) from the regular parameters before the mode validation phase begins. The rest of the code conditionally uses the crtc_* parameters only during the bridge enable phase, but sticks to the regular parameters for mode validation. In this singular instance, however, the driver tries to use the crtc_clock parameter even during the mode validation, causing the validation to fail. Allow the D-Phy config checks to use mode->clock instead of mode->crtc_clock during mode_valid checks, like everywhere else in the driver.

[PATCH v9 02/13] drm/bridge: cdns-dsi: Fix phy de-init and flag it so

by Aradhya Bhatia

From: Aradhya Bhatia <a-bhatia1(a)ti.com> The driver code doesn't have a Phy de-initialization path as yet, and so it does not clear the phy_initialized flag while suspending. This is a problem because after resume the driver looks at this flag to determine if a Phy re-initialization is required or not. It is in fact required because the hardware is resuming from a suspend, but the driver does not carry out any re-initialization causing the D-Phy to not work at all. Call the counterparts of phy_init() and phy_power_on(), that are phy_exit() and phy_power_off(), from _bridge_post_disable(), and clear the flags so that the Phy can be initialized again when required.

[PATCH v9 01/13] drm/bridge: cdns-dsi: Fix connecting to next bridge

by Aradhya Bhatia

From: Aradhya Bhatia <a-bhatia1(a)ti.com> Fix the OF node pointer passed to the of_drm_find_bridge() call to find the next bridge in the display chain. The code to find the next panel (and create its panel-bridge) works fine, but to find the next (non-panel) bridge does not. To find the next bridge in the pipeline, we need to pass "np" - the OF node pointer of the next entity in the devicetree chain. Passing "of_node" to of_drm_find_bridge (which is what the code does currently) will fetch the bridge for the cdns-dsi which is not what's required. Fix that.

[PATCH] crypto: ccp - Fix check for the primary ASP device

by Tom Lendacky

Currently, the ASP primary device check does not have support for PCI domains, and, as a result, when the system is configured with PCI domains (PCI segments) the wrong device can be selected as primary. This results in commands submitted to the device timing out and failing. The device check also relies on specific device and function assignments that may not hold in the future. Fix the primary ASP device check to include support for PCI domains and to perform proper checking of the Bus/Device/Function positions.

[PATCH] mtd: rawnand: qcom: fix broken config in qcom_param_page_type_exec

by Christian Marangi

[PATCH net 2/6] can: j1939: j1939_sk_send_loop(): fix unable to send messages with data length zero

by Marc Kleine-Budde

From: Alexander Hölzl <alexander.hoelzl(a)gmx.net> The J1939 standard requires the transmission of messages of length 0. For example proprietary messages are specified with a data length of 0 to 1785. The transmission of such messages is not possible. Sending results in no error being returned but no corresponding can frame being generated. Enable the transmission of zero length J1939 messages. In order to facilitate this two changes are necessary: 1) If the transmission of a new message is requested from user space the message is segmented in j1939_sk_send_loop(). Let the segmentation take into account zero length messages, do not terminate immediately, queue the corresponding skb. 2) j1939_session_skb_get_by_offset() selects the next skb to transmit for a session. Take into account that there might be zero length skbs in the queue.

[PATCH 6.1.y] cachefiles: Fix NULL pointer dereference in object->file

by lanbincn＠qq.com

From: Zizhi Wo <wozizhi(a)huawei.com> commit 31ad74b20227ce6b40910ff78b1c604e42975cf1 upstream. At present, the object->file has the NULL pointer dereference problem in ondemand-mode. The root cause is that the allocated fd and object->file lifetime are inconsistent, and the user-space invocation to anon_fd uses object->file. Following is the process that triggers the issue: [write fd] [umount] cachefiles_ondemand_fd_write_iter fscache_cookie_state_machine cachefiles_withdraw_cookie if (!file) return -ENOBUFS cachefiles_clean_up_object cachefiles_unmark_inode_in_use fput(object->file) object->file = NULL // file NULL pointer dereference! __cachefiles_write(..., file, ...) Fix this issue by add an additional reference count to the object->file before write/llseek, and decrement after it finished.

[PATCH] usb: cdns3: exit cdns3_gadget_udc_start if FAST_REG_ACCESS cannot be set

by Siddharth Vadapalli

When the device is in a low power state, access to the following registers takes a long time: - EP_CFG - EP_TRADDR - EP_CMD - EP_SEL - EP_STS - USB_CONF To address this, the fast register access feature can be enabled by setting PUSB_PWR_FST_REG_ACCESS bit of the USB_PWR register, which allows quick access by software. Software is expected to poll on PUSB_PWR_FST_REG_ACCESS_STAT to ensure that fast register access has been enabled by the controller. Attempting to access any of the aforementioned registers after setting PUSB_PWR_FST_REG_ACCESS but before PUSB_PWR_FST_REG_ACCESS_STAT has been set will result in undefined behavior and potentially result in system hang.

[PATCH 6.1.y v2] net: dsa: fix netdev_priv() dereference before check on non-DSA netdevice events

by jetlan9＠163.com

From: Vladimir Oltean <vladimir.oltean(a)nxp.com> commit 844f104790bd69c2e4dbb9ee3eba46fde1fcea7b upstream. After the blamed commit, we started doing this dereference for every NETDEV_CHANGEUPPER and NETDEV_PRECHANGEUPPER event in the system. static inline struct dsa_port *dsa_user_to_port(const struct net_device *dev) { struct dsa_user_priv *p = netdev_priv(dev); return p->dp; } Which is obviously bogus, because not all net_devices have a netdev_priv() of type struct dsa_user_priv. But struct dsa_user_priv is fairly small, and p->dp means dereferencing 8 bytes starting with offset 16. Most drivers allocate that much private memory anyway, making our access not fault, and we discard the bogus data quickly afterwards, so this wasn't caught. But the dummy interface is somewhat special in that it calls alloc_netdev() with a priv size of 0. So every netdev_priv() dereference is invalid, and we get this when we emit a NETDEV_PRECHANGEUPPER event with a VLAN as its new upper: $ ip link add dummy1 type dummy $ ip link add link dummy1 name dummy1.100 type vlan id 100 [ 43.309174] ================================================================== [ 43.316456] BUG: KASAN: slab-out-of-bounds in dsa_user_prechangeupper+0x30/0xe8 [ 43.323835] Read of size 8 at addr ffff3f86481d2990 by task ip/374 [ 43.330058] [ 43.342436] Call trace: [ 43.366542] dsa_user_prechangeupper+0x30/0xe8 [ 43.371024] dsa_user_netdevice_event+0xb38/0xee8 [ 43.375768] notifier_call_chain+0xa4/0x210 [ 43.379985] raw_notifier_call_chain+0x24/0x38 [ 43.384464] __netdev_upper_dev_link+0x3ec/0x5d8 [ 43.389120] netdev_upper_dev_link+0x70/0xa8 [ 43.393424] register_vlan_dev+0x1bc/0x310 [ 43.397554] vlan_newlink+0x210/0x248 [ 43.401247] rtnl_newlink+0x9fc/0xe30 [ 43.404942] rtnetlink_rcv_msg+0x378/0x580 Avoid the kernel oops by dereferencing after the type check, as customary.

[PATCH 6.1.y] net: dsa: fix netdev_priv() dereference before check on non-DSA netdevice events

by jetlan9＠163.com

From: Vladimir Oltean <vladimir.oltean(a)nxp.com> After the blamed commit, we started doing this dereference for every NETDEV_CHANGEUPPER and NETDEV_PRECHANGEUPPER event in the system. static inline struct dsa_port *dsa_user_to_port(const struct net_device *dev) { struct dsa_user_priv *p = netdev_priv(dev); return p->dp; } Which is obviously bogus, because not all net_devices have a netdev_priv() of type struct dsa_user_priv. But struct dsa_user_priv is fairly small, and p->dp means dereferencing 8 bytes starting with offset 16. Most drivers allocate that much private memory anyway, making our access not fault, and we discard the bogus data quickly afterwards, so this wasn't caught. But the dummy interface is somewhat special in that it calls alloc_netdev() with a priv size of 0. So every netdev_priv() dereference is invalid, and we get this when we emit a NETDEV_PRECHANGEUPPER event with a VLAN as its new upper: $ ip link add dummy1 type dummy $ ip link add link dummy1 name dummy1.100 type vlan id 100 [ 43.309174] ================================================================== [ 43.316456] BUG: KASAN: slab-out-of-bounds in dsa_user_prechangeupper+0x30/0xe8 [ 43.323835] Read of size 8 at addr ffff3f86481d2990 by task ip/374 [ 43.330058] [ 43.342436] Call trace: [ 43.366542] dsa_user_prechangeupper+0x30/0xe8 [ 43.371024] dsa_user_netdevice_event+0xb38/0xee8 [ 43.375768] notifier_call_chain+0xa4/0x210 [ 43.379985] raw_notifier_call_chain+0x24/0x38 [ 43.384464] __netdev_upper_dev_link+0x3ec/0x5d8 [ 43.389120] netdev_upper_dev_link+0x70/0xa8 [ 43.393424] register_vlan_dev+0x1bc/0x310 [ 43.397554] vlan_newlink+0x210/0x248 [ 43.401247] rtnl_newlink+0x9fc/0xe30 [ 43.404942] rtnetlink_rcv_msg+0x378/0x580 Avoid the kernel oops by dereferencing after the type check, as customary.

Add a field for DAMOS scheme object that can be used by the underlying ops to know what was the last entity that the scheme's action has applied. The core layer unsets the field when each DAMOS-regions-walk is done for the given scheme. And update 'paddr' ops to use the infrastructure to avoid the problem.

DAMON operations set for physical address space, namely 'paddr', treats tail pages as unaccessed always. It can also apply DAMOS action to a large folio multiple times within single DAMOS' regions walking. As a result, the monitoring output has poor quality and DAMOS works in unexpected ways when large folios are being used. Fix those. The patches were parts of Usama's hugepage_size DAMOS filter patch series[1]. The first fix has collected from there with a slight commit message change for the subject prefix. The second fix is re-written by SJ and posted as an RFC before this series. The second one also got a slight commit message change for the subject prefix. [1] https://lore.kernel.org/20250203225604.44742-1-usamaarif642@gmail.com [2] https://lore.kernel.org/20250206231103.38298-1-sj@kernel.org This patch (of 2): This effectively adds support for large folios in damon for paddr, as damon_pa_mkold/young won't get a null folio from this function and won't ignore it, hence access will be checked and reported. This also means that larger folios will be considered for different DAMOS actions like pageout, prioritization and migration.

[PATCH v3 0/2] rust: lockdep: Fix soundness issue affecting LockClassKeys

by Mitchell Levy

This series is aimed at fixing a soundness issue with how dynamically allocated LockClassKeys are handled. Currently, LockClassKeys can be used without being Pin'd, which can break lockdep since it relies on address stability. Similarly, these keys are not automatically (de)registered with lockdep. At the suggestion of Alice Ryhl, this series includes a patch for -stable kernels that disables dynamically allocated keys. This prevents backported patches from using the unsound implementation. Currently, this series requires that all dynamically allocated LockClassKeys have a lifetime of 'static (i.e., they must be leaked after allocation). This is because Lock does not currently keep a reference to the LockClassKey, instead passing it to C via FFI. This causes a problem because the rust compiler would allow creating a 'static Lock with a 'a LockClassKey (with 'a < 'static) while C would expect the LockClassKey to live as long as the lock. This problem represents an avenue for future work. --- Changes in v3: - Rebased on rust-next - Fixed clippy/compiler warninings (Thanks Boqun Feng) - Link to v2: https://lore.kernel.org/r/20241219-rust-lockdep-v2-0-f65308fbc5ca@gmail.com Changes in v2: - Dropped formatting change that's already fixed upstream (Thanks Dirk Behme). - Moved safety comment to the right point in the patch series (Thanks Dirk Behme and Boqun Feng). - Added an example of dynamic LockClassKey usage (Thanks Boqun Feng). - Link to v1: https://lore.kernel.org/r/20241004-rust-lockdep-v1-0-e9a5c45721fc@gmail.com Changes from RFC: - Split into two commits so that dynamically allocated LockClassKeys are removed from stable kernels. (Thanks Alice Ryhl) - Extract calls to C lockdep functions into helpers so things build properly when LOCKDEP=n. (Thanks Benno Lossin) - Remove extraneous `get_ref()` calls.

Qualcomm Kryo 400-series Gold cores have a derivative of an ARM Cortex A76 in them.

[PATCH 5.4 5.10 5.15 0/3] nilfs2: protect busy buffer heads from being force-cleared

by Ryusuke Konishi

Please apply this series to the stable trees indicated by the subject prefix. This series makes it possible to backport the latter two patches (fixing some syzbot issues and a use-after-free issue) that could not be backported as-is. To achieve this, one dependent patch (patch 1/3) is included, and each patch is tailored to avoid extensive page/folio conversion. Both adjustments are specific to nilfs2 and do not include tree-wide changes. It has also been tested against the latest versions of each tree. Thanks, Ryusuke Konishi Ryusuke Konishi (3): nilfs2: do not output warnings when clearing dirty buffers nilfs2: do not force clear folio if buffer is referenced nilfs2: protect access to buffers with no active references fs/nilfs2/inode.c | 4 ++-- fs/nilfs2/mdt.c | 6 ++--- fs/nilfs2/page.c | 55 ++++++++++++++++++++++++++------------------- fs/nilfs2/page.h | 4 ++-- fs/nilfs2/segment.c | 4 +++- 5 files changed, 42 insertions(+), 31 deletions(-) -- 2.43.5

Kernel panic - not syncing: Oops - BUG: Fatal exception This happens because pps_device_destruct() frees the pps_device with the embedded cdev immediately after calling cdev_del(), but, as the comment above cdev_del() notes, fops for previously opened cdevs are still callable even after cdev_del() returns. I think this bug has always been there: I can't explain why it suddenly started happening every time I reboot this particular board. In commit d953e0e837e6 ("pps: Fix a use-after free bug when unregistering a source."), George Spelvin suggested removing the embedded cdev. That seems like the simplest way to fix this, so I've implemented his suggestion, using __register_chrdev() with pps_idr becoming the source of truth for which minor corresponds to which device. But now that pps_idr defines userspace visibility instead of cdev_add(), we need to be sure the pps->dev refcount can't reach zero while userspace can still find it again. So, the idr_remove() call moves to pps_unregister_cdev(), and pps_idr now holds a reference to pps->dev. pps_core: source serial1 got cdev (251:1) <...> pps pps1: removed pps_core: unregistering pps1 pps_core: deallocating pps1 Fixes: d953e0e837e6 ("pps: Fix a use-after free bug when unregistering a source.")

Kernel panic - not syncing: Oops - BUG: Fatal exception This happens because pps_device_destruct() frees the pps_device with the embedded cdev immediately after calling cdev_del(), but, as the comment above cdev_del() notes, fops for previously opened cdevs are still callable even after cdev_del() returns. I think this bug has always been there: I can't explain why it suddenly started happening every time I reboot this particular board. In commit d953e0e837e6 ("pps: Fix a use-after free bug when unregistering a source."), George Spelvin suggested removing the embedded cdev. That seems like the simplest way to fix this, so I've implemented his suggestion, using __register_chrdev() with pps_idr becoming the source of truth for which minor corresponds to which device.

[PATCH] Documentation/no_hz: Remove description that states boot CPU cannot be nohz_full

by Krishanth Jagaduri via B4 Relay

From: Oleg Nesterov <oleg(a)redhat.com> [ Upstream commit 5097cbcb38e6e0d2627c9dde1985e91d2c9f880e ] Documentation/timers/no_hz.rst states that the "nohz_full=" mask must not include the boot CPU, which is no longer true after: commit 08ae95f4fd3b ("nohz_full: Allow the boot CPU to be nohz_full").

This was fixed upstream by commit 5097cbcb38e6 ("sched/isolation: Prevent boot crash when the boot CPU is nohz_full"). While it fixes the document description, it also fixes issue introduced by another commit aae17ebb53cd ("workqueue: Avoid using isolated cpus' timers on queue_delayed_work"). It is unlikely that it will be backported to stable kernels which does not contain the commit that introduced the issue.

Kernel panic - not syncing: Oops - BUG: Fatal exception This happens because pps_device_destruct() frees the pps_device with the embedded cdev immediately after calling cdev_del(), but, as the comment above cdev_del() notes, fops for previously opened cdevs are still callable even after cdev_del() returns. I think this bug has always been there: I can't explain why it suddenly started happening every time I reboot this particular board. In commit d953e0e837e6 ("pps: Fix a use-after free bug when unregistering a source."), George Spelvin suggested removing the embedded cdev. That seems like the simplest way to fix this, so I've implemented his suggestion, using __register_chrdev() with pps_idr becoming the source of truth for which minor corresponds to which device. But now that pps_idr defines userspace visibility instead of cdev_add(), we need to be sure the pps->dev refcount can't reach zero while userspace can still find it again. So, the idr_remove() call moves to pps_unregister_cdev(), and pps_idr now holds a reference to pps->dev. pps_core: source serial1 got cdev (251:1) <...> pps pps1: removed pps_core: unregistering pps1 pps_core: deallocating pps1 Fixes: d953e0e837e6 ("pps: Fix a use-after free bug when unregistering a source.")

Kernel panic - not syncing: Oops - BUG: Fatal exception This happens because pps_device_destruct() frees the pps_device with the embedded cdev immediately after calling cdev_del(), but, as the comment above cdev_del() notes, fops for previously opened cdevs are still callable even after cdev_del() returns. I think this bug has always been there: I can't explain why it suddenly started happening every time I reboot this particular board. In commit d953e0e837e6 ("pps: Fix a use-after free bug when unregistering a source."), George Spelvin suggested removing the embedded cdev. That seems like the simplest way to fix this, so I've implemented his suggestion, using __register_chrdev() with pps_idr becoming the source of truth for which minor corresponds to which device. But now that pps_idr defines userspace visibility instead of cdev_add(), we need to be sure the pps->dev refcount can't reach zero while userspace can still find it again. So, the idr_remove() call moves to pps_unregister_cdev(), and pps_idr now holds a reference to pps->dev. pps_core: source serial1 got cdev (251:1) <...> pps pps1: removed pps_core: unregistering pps1 pps_core: deallocating pps1 Fixes: d953e0e837e6 ("pps: Fix a use-after free bug when unregistering a source.")

[PATCH 6.1 5.15 5.10 5.4 0/3] Backport ASIX AX99100 support

by Tomita Moeko

This patchset backports ASIX AX99100 pcie serial/parallel port controller support to linux 6.1 5.15 5.10 5.4. It just add a device ID, no functional changes included. The commit 3029ad913353("can: ems_pci: move ASIX AX99100 ids to pci_ids.h") was renamed to "PCI: add ASIX AX99100 ids to pci_ids.h", and changes in drivers/net/can/sja1000/ems_pci.c were dropped as the ems_pci change are only relevant for linux 6.3 and later.

[PATCH 6.1 0/3] nilfs2: protect busy buffer heads from being force-cleared

by Ryusuke Konishi

Please apply this series to the 6.1-stable tree. This series makes it possible to backport the latter two patches (fixing some syzbot issues and a use-after-free issue) that could not be backported to 6.1.y. To achieve this, one dependent patch (patch 1/3) is included, and each patch is tailored to avoid extensive page/folio conversion. Both adjustments are specific to nilfs2 and do not include tree-wide changes. It has also been tested against the latest 6.1.y.

[PATCH Linux-6.12.y 1/1] selftests/bpf: Add test to verify tailcall and freplace restrictions

by Yifei Liu

From: Leon Hwang <leon.hwang(a)linux.dev> [ Upstream commit 021611d33e78694f4bd54573093c6fc70a812644 ] Add a test case to ensure that attaching a tail callee program with an freplace program fails, and that updating an extended program to a prog_array map is also prohibited. This test is designed to prevent the potential infinite loop issue caused by the combination of tail calls and freplace, ensuring the correct behavior and stability of the system. Additionally, fix the broken tailcalls/tailcall_freplace selftest because an extension prog should not be tailcalled. cd tools/testing/selftests/bpf; ./test_progs -t tailcalls 337/25 tailcalls/tailcall_freplace:OK 337/26 tailcalls/tailcall_bpf2bpf_freplace:OK 337 tailcalls:OK Summary: 1/26 PASSED, 0 SKIPPED, 0 FAILED Acked-by: Eduard Zingerman <eddyz87(a)gmail.com> Signed-off-by: Leon Hwang <leon.hwang(a)linux.dev> Link: https://lore.kernel.org/r/20241015150207.70264-3-leon.hwang@linux.dev Signed-off-by: Alexei Starovoitov <ast(a)kernel.org> (cherry picked from commit 021611d33e78694f4bd54573093c6fc70a812644) [Yifei: bpf freplace update is backported to linux-6.12 by commit 987aa730bad3 ("bpf: Prevent tailcall infinite loop caused by freplace").

[PATCH 0/2] mm/damon/paddr: fix large folios access and schemes handling

by SeongJae Park

DAMON operations set for physical address space, namely 'paddr', treats tail pages as unaccessed always. It can also apply DAMOS action to a large folio multiple times within single DAMOS' regions walking. As a result, the monitoring output has poor quality and DAMOS works in unexpected ways when large folios are being used. Fix those. The patches were parts of Usama's hugepage_size DAMOS filter patch series[1]. The first fix has collected from there with a slight commit message change for the subject prefix. The second fix is re-written by SJ and posted as an RFC before this series. The second one also got a slight commit message change for the subject prefix.

[PATCH 5.10/5.15] i3c: master: cdns: Fix use after free vulnerability in cdns_i3c_master Driver Due to Race Condition

[PATCH v2] mtd: Add check and kfree() for kcalloc()

[PATCH RFC] soc: qcom: pmic_glink: Fix device access from worker during suspend

by Abel Vesa

The pmic_glink_altmode_worker() currently gets scheduled on the system_wq. When the system is suspended (s2idle), the fact that the worker can be scheduled to run while devices are still suspended provesto be a problem when a Type-C retimer, switch or mux that is controlled over a bus like I2C, because the I2C controller is suspended. This has been proven to be the case on the X Elite boards where such retimers (ParadeTech PS8830) are used in order to handle Type-C orientation and altmode configuration. The following warning is thrown: [ 35.134876] i2c i2c-4: Transfer while suspended [ 35.143865] WARNING: CPU: 0 PID: 99 at drivers/i2c/i2c-core.h:56 __i2c_transfer+0xb4/0x57c [i2c_core] [ 35.352879] Workqueue: events pmic_glink_altmode_worker [pmic_glink_altmode] [ 35.360179] pstate: 61400005 (nZCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--) [ 35.455242] Call trace: [ 35.457826] __i2c_transfer+0xb4/0x57c [i2c_core] (P) [ 35.463086] i2c_transfer+0x98/0xf0 [i2c_core] [ 35.467713] i2c_transfer_buffer_flags+0x54/0x88 [i2c_core] [ 35.473502] regmap_i2c_write+0x20/0x48 [regmap_i2c] [ 35.478659] _regmap_raw_write_impl+0x780/0x944 [ 35.483401] _regmap_bus_raw_write+0x60/0x7c [ 35.487848] _regmap_write+0x134/0x184 [ 35.491773] regmap_write+0x54/0x78 [ 35.495418] ps883x_set+0x58/0xec [ps883x] [ 35.499688] ps883x_sw_set+0x60/0x84 [ps883x] [ 35.504223] typec_switch_set+0x48/0x74 [typec] [ 35.508952] pmic_glink_altmode_worker+0x44/0x1fc [pmic_glink_altmode] [ 35.515712] process_scheduled_works+0x1a0/0x2d0 [ 35.520525] worker_thread+0x2a8/0x3c8 [ 35.524449] kthread+0xfc/0x184 [ 35.527749] ret_from_fork+0x10/0x20 The solution here is to schedule the altmode worker on the system_freezable_wq instead of the system_wq.

From: Niravkumar L Rabara <niravkumar.l.rabara(a)intel.com> This patchset introduces improvements and fixes for cadence nand driver. The changes include: 1. Support deferred prob mechanism when DMA driver is not probed yet. 2. Map the slave DMA address using dma_map_resource. When ARM SMMU is enabled, using a direct physical address of SDMA results in DMA transaction failure. 3.

[PATCH v2] serial: 8250: Fix fifo underflow on flush

by John Keeping

When flushing the serial port's buffer, uart_flush_buffer() calls kfifo_reset() but if there is an outstanding DMA transfer then the completion function will consume data from the kfifo via uart_xmit_advance(), underflowing and leading to ongoing DMA as the driver tries to transmit another 2^32 bytes. This is readily reproduced with serial-generic and amidi sending even short messages as closing the device on exit will wait for the fifo to drain and in the underflow case amidi hangs for 30 seconds on exit in tty_wait_until_sent(). A trace of that gives: kworker/1:1-84 [001] 51.769423: bprint: serial8250_tx_dma: tx_size=3 fifo_len=3 amidi-763 [001] 51.769460: bprint: uart_flush_buffer: resetting fifo irq/21-fe530000-76 [000] 51.769474: bprint: __dma_tx_complete: tx_size=3 irq/21-fe530000-76 [000] 51.769479: bprint: serial8250_tx_dma: tx_size=4096 fifo_len=4294967293 irq/21-fe530000-76 [000] 51.781295: bprint: __dma_tx_complete: tx_size=4096 irq/21-fe530000-76 [000] 51.781301: bprint: serial8250_tx_dma: tx_size=4096 fifo_len=4294963197 irq/21-fe530000-76 [000] 51.793131: bprint: __dma_tx_complete: tx_size=4096 irq/21-fe530000-76 [000] 51.793135: bprint: serial8250_tx_dma: tx_size=4096 fifo_len=4294959101 irq/21-fe530000-76 [000] 51.804949: bprint: __dma_tx_complete: tx_size=4096 Since the port lock is held in when the kfifo is reset in uart_flush_buffer() and in __dma_tx_complete(), adding a flush_buffer hook to adjust the outstanding DMA byte count is sufficient to avoid the kfifo underflow.

[PATCH] pidfs: improve ioctl handling

by Christian Brauner

Pidfs supports extensible and non-extensible ioctls. The extensible ioctls need to check for the ioctl number itself not just the ioctl command otherwise both backward- and forward compatibility are broken. The pidfs ioctl handler also needs to look at the type of the ioctl command to guard against cases where "[...] a daemon receives some random file descriptor from a (potentially less privileged) client and expects the FD to be of some specific type, it might call ioctl() on this FD with some type-specific command and expect the call to fail if the FD is of the wrong type; but due to the missing type check, the kernel instead performs some action that userspace didn't expect."

[PATCH 4/4] batman-adv: Fix incorrect offset in batadv_tt_tvlv_ogm_handler_v1()

by Simon Wunderlich

From: Remi Pommarel <repk(a)triplefau.lt> Since commit 4436df478860 ("batman-adv: Add flex array to struct batadv_tvlv_tt_data"), the introduction of batadv_tvlv_tt_data's flex array member in batadv_tt_tvlv_ogm_handler_v1() put tt_changes at invalid offset. Those TT changes are supposed to be filled from the end of batadv_tvlv_tt_data structure (including vlan_data flexible array), but only the flex array size is taken into account missing completely the size of the fixed part of the structure itself. Fix the tt_change offset computation by using struct_size() instead of flex_array_size() so both flex array member and its container structure sizes are taken into account.

[PATCH 3/4] batman-adv: Drop unmanaged ELP metric worker

by Simon Wunderlich

From: Sven Eckelmann <sven(a)narfation.org> The ELP worker needs to calculate new metric values for all neighbors "reachable" over an interface. Some of the used metric sources require locks which might need to sleep. This sleep is incompatible with the RCU list iterator used for the recorded neighbors. The initial approach to work around of this problem was to queue another work item per neighbor and then run this in a new context. Even when this solved the RCU vs might_sleep() conflict, it has a major problems: Nothing was stopping the work item in case it is not needed anymore - for example because one of the related interfaces was removed or the batman-adv module was unloaded - resulting in potential invalid memory accesses. Directly canceling the metric worker also has various problems: * cancel_work_sync for a to-be-deactivated interface is called with rtnl_lock held. But the code in the ELP metric worker also tries to use rtnl_lock() - which will never return in this case. This also means that cancel_work_sync would never return because it is waiting for the worker to finish. * iterating over the neighbor list for the to-be-deactivated interface is currently done using the RCU specific methods. Which means that it is possible to miss items when iterating over it without the associated spinlock - a behaviour which is acceptable for a periodic metric check but not for a cleanup routine (which must "stop" all still running workers) The better approch is to get rid of the per interface neighbor metric worker and handle everything in the interface worker. The original problems are solved by: * creating a list of neighbors which require new metric information inside the RCU protected context, gathering the metric according to the new list outside the RCU protected context * only use rcu_trylock inside metric gathering code to avoid a deadlock when the cancel_delayed_work_sync is called in the interface removal code (which is called with the rtnl_lock held) Cc: stable(a)vger.kernel.org Fixes: c833484e5f38 ("batman-adv: ELP - compute the metric based on the estimated throughput") Signed-off-by: Sven Eckelmann <sven(a)narfation.org> Signed-off-by: Simon Wunderlich <sw(a)simonwunderlich.de> --- net/batman-adv/bat_v.c | 2 -- net/batman-adv/bat_v_elp.c | 71 ++++++++++++++++++++++++++------------ net/batman-adv/bat_v_elp.h | 2 -- net/batman-adv/types.h | 3 -- 4 files changed, 48 insertions(+), 30 deletions(-) diff --git a/net/batman-adv/bat_v.c b/net/batman-adv/bat_v.c index ac11f1f08db0..d35479c465e2 100644 --- a/net/batman-adv/bat_v.c +++ b/net/batman-adv/bat_v.c @@ -113,8 +113,6 @@ static void batadv_v_hardif_neigh_init(struct batadv_hardif_neigh_node *hardif_neigh) { ewma_throughput_init(&hardif_neigh->bat_v.throughput); - INIT_WORK(&hardif_neigh->bat_v.metric_work, - batadv_v_elp_throughput_metric_update); } /** diff --git a/net/batman-adv/bat_v_elp.c b/net/batman-adv/bat_v_elp.c index 65e52de52bcd..b065578b4436 100644 --- a/net/batman-adv/bat_v_elp.c +++ b/net/batman-adv/bat_v_elp.c @@ -18,6 +18,7 @@ #include <linux/if_ether.h> #include <linux/jiffies.h> #include <linux/kref.h> +#include <linux/list.h> #include <linux/minmax.h> #include <linux/netdevice.h> #include <linux/nl80211.h> @@ -26,6 +27,7 @@ #include <linux/rcupdate.h> #include <linux/rtnetlink.h> #include <linux/skbuff.h> +#include <linux/slab.h> #include <linux/stddef.h> #include <linux/string.h> #include <linux/types.h> @@ -41,6 +43,18 @@ #include "routing.h" #include "send.h" +/** + * struct batadv_v_metric_queue_entry - list of hardif neighbors which require + * and metric update + */ +struct batadv_v_metric_queue_entry { + /** @hardif_neigh: hardif neighbor scheduled for metric update */ + struct batadv_hardif_neigh_node *hardif_neigh; + + /** @list: list node for metric_queue */ + struct list_head list; +}; + /** * batadv_v_elp_start_timer() - restart timer for ELP periodic work * @hard_iface: the interface for which the timer has to be reset @@ -137,10 +151,17 @@ static bool batadv_v_elp_get_throughput(struct batadv_hardif_neigh_node *neigh, goto default_throughput; } + /* only use rtnl_trylock because the elp worker will be cancelled while + * the rntl_lock is held. the cancel_delayed_work_sync() would otherwise + * wait forever when the elp work_item was started and it is then also + * trying to rtnl_lock + */ + if (!rtnl_trylock()) + return false; + /* if not a wifi interface, check if this device provides data via * ethtool (e.g. an Ethernet adapter) */ - rtnl_lock(); ret = __ethtool_get_link_ksettings(hard_iface->net_dev, &link_settings); rtnl_unlock(); if (ret == 0) { @@ -175,31 +196,19 @@ static bool batadv_v_elp_get_throughput(struct batadv_hardif_neigh_node *neigh, /** * batadv_v_elp_throughput_metric_update() - worker updating the throughput * metric of a single hop neighbour - * @work: the work queue item + * @neigh: the neighbour to probe */ -void batadv_v_elp_throughput_metric_update(struct work_struct *work) +static void +batadv_v_elp_throughput_metric_update(struct batadv_hardif_neigh_node *neigh) { - struct batadv_hardif_neigh_node_bat_v *neigh_bat_v; - struct batadv_hardif_neigh_node *neigh; u32 throughput; bool valid; - neigh_bat_v = container_of(work, struct batadv_hardif_neigh_node_bat_v, - metric_work); - neigh = container_of(neigh_bat_v, struct batadv_hardif_neigh_node, - bat_v); - valid = batadv_v_elp_get_throughput(neigh, &throughput); if (!valid) - goto put_neigh; + return; ewma_throughput_add(&neigh->bat_v.throughput, throughput); - -put_neigh: - /* decrement refcounter to balance increment performed before scheduling - * this task - */ - batadv_hardif_neigh_put(neigh); } /** @@ -273,14 +282,16 @@ batadv_v_elp_wifi_neigh_probe(struct batadv_hardif_neigh_node *neigh) */ static void batadv_v_elp_periodic_work(struct work_struct *work) { + struct batadv_v_metric_queue_entry *metric_entry; + struct batadv_v_metric_queue_entry *metric_safe; struct batadv_hardif_neigh_node *hardif_neigh; struct batadv_hard_iface *hard_iface; struct batadv_hard_iface_bat_v *bat_v; struct batadv_elp_packet *elp_packet; + struct list_head metric_queue; struct batadv_priv *bat_priv; struct sk_buff *skb; u32 elp_interval; - bool ret; bat_v = container_of(work, struct batadv_hard_iface_bat_v, elp_wq.work); hard_iface = container_of(bat_v, struct batadv_hard_iface, bat_v); @@ -316,6 +327,8 @@ static void batadv_v_elp_periodic_work(struct work_struct *work) atomic_inc(&hard_iface->bat_v.elp_seqno); + INIT_LIST_HEAD(&metric_queue); + /* The throughput metric is updated on each sent packet.

[PATCH] fs/xattr: actually support O_PATH fds in *xattrat() syscalls

by Mike Yuan

Cited from commit message of original patch [1]: > One use case will be setfiles(8) setting SELinux file contexts > ("security.selinux") without race conditions and without a file > descriptor opened with read access requiring SELinux read permission. Also, generally all *at() syscalls operate on O_PATH fds, unlike f*() ones. Yet the O_PATH fds are rejected by *xattrat() syscalls in the final version merged into tree. Instead, let's switch things to CLASS(fd_raw). Note that there's one side effect: f*xattr() starts to work with O_PATH fds too. It's not clear to me whether this is desirable (e.g. fstat() accepts O_PATH fds as an outlier).

[tip: timers/urgent] timers/migration: Fix off-by-one root mis-connection

by tip-bot2 for Frederic Weisbecker

The following commit has been merged into the timers/urgent branch of tip: Commit-ID: 868c9037df626b3c245ee26a290a03ae1f9f58d3 Gitweb: https://git.kernel.org/tip/868c9037df626b3c245ee26a290a03ae1f9f58d3 Author: Frederic Weisbecker <frederic(a)kernel.org> AuthorDate: Wed, 05 Feb 2025 17:02:20 +01:00 Committer: Thomas Gleixner <tglx(a)linutronix.de> CommitterDate: Fri, 07 Feb 2025 09:02:16 +01:00 timers/migration: Fix off-by-one root mis-connection Before attaching a new root to the old root, the children counter of the new root is checked to verify that only the upcoming CPU's top group have been connected to it. However since the recently added commit b729cc1ec21a ("timers/migration: Fix another race between hotplug and idle entry/exit") this check is not valid anymore because the old root is pre-accounted as a child to the new root. Therefore after connecting the upcoming CPU's top group to the new root, the children count to be expected must be 2 and not 1 anymore. This omission results in the old root to not be connected to the new root. Then eventually the system may run with more than one top level, which defeats the purpose of a single idle migrator. Also the old root is pre-accounted but not connected upon the new root creation. But it can be connected to the new root later on. Therefore the old root may be accounted twice to the new root. The propagation of such overcommit can end up creating a double final top-level root with a groupmask incorrectly initialized. Although harmless given that the final top level roots will never have a parent to walk up to, this oddity opportunistically reported the core issue: WARNING: CPU: 8 PID: 0 at kernel/time/timer_migration.c:543 tmigr_requires_handle_remote CPU: 8 UID: 0 PID: 0 Comm: swapper/8 RIP: 0010:tmigr_requires_handle_remote Call Trace: <IRQ> ? tmigr_requires_handle_remote ? hrtimer_run_queues update_process_times tick_periodic tick_handle_periodic __sysvec_apic_timer_interrupt sysvec_apic_timer_interrupt </IRQ> Fix the problem by taking the old root into account in the children count of the new root so the connection is not omitted.

[PATCH v1 2/2] arm64: dts: qcom: ipq9574: Fix USB vdd info

by Varadarajan Narayanan

USB phys in ipq9574 use the 'L5' regulator. The commit ec4f047679d5 ("arm64: dts: qcom: ipq9574: Enable USB") incorrectly specified it as 'L2'. Because of this when the phy module turns off/on its regulators, 'L2' is turned off/on resulting in 2 issues, namely 'L5' is not turned off/on and the network module powered by the 'L2' is turned off/on.

[PATCH] x86: rust: set rustc-abi=x86-softfloat on rustc>=1.86.0

by Alice Ryhl

When using Rust on the x86 architecture, we are currently using the unstable target.json feature to specify the compilation target. Rustc is going to change how softfloat is specified in the target.json file on x86, thus update generate_rust_target.rs to specify softfloat using the new option. Note that if you enable this parameter with a compiler that does not recognize it, then that triggers a warning but it does not break the build.

[PATCH] arm64: tegra: delete the Orin NX/Nano suspend key

by Ivy Huang

From: Ninad Malwade <nmalwade(a)nvidia.com> As per the Orin Nano Dev Kit schematic, GPIO_G.02 is not available on this device family. It should not be used at all on Orin NX/Nano. Having this unused pin mapped as the suspend key can lead to unpredictable behavior for low power modes. Orin NX/Nano uses GPIO_EE.04 as both a "power" button and a "suspend" button. However, we cannot have two gpio-keys mapped to the same GPIO. Therefore delete the "suspend" key.

[PATCH v3 1/2] seccomp: passthrough uretprobe systemcall without filtering

by Eyal Birger

When attaching uretprobes to processes running inside docker, the attached process is segfaulted when encountering the retprobe. The reason is that now that uretprobe is a system call the default seccomp filters in docker block it as they only allow a specific set of known syscalls. This is true for other userspace applications which use seccomp to control their syscall surface. Since uretprobe is a "kernel implementation detail" system call which is not used by userspace application code directly, it is impractical and there's very little point in forcing all userspace applications to explicitly allow it in order to avoid crashing tracked processes. Pass this systemcall through seccomp without depending on configuration. Note: uretprobe isn't supported in i386 and __NR_ia32_rt_tgsigqueueinfo uses the same number as __NR_uretprobe so the syscall isn't forced in the compat bitmap.

[PATCH 1/2] smb: client: change lease epoch type from unsigned int to __u16

by meetakshisetiyaoss＠gmail.com

From: Meetakshi Setiya <msetiya(a)microsoft.com> MS-SMB2 section 2.2.13.2.10 specifies that 'epoch' should be a 16-bit unsigned integer used to track lease state changes. Change the data type of all instances of 'epoch' from unsigned int to __u16. This simplifies the epoch change comparisons and makes the code more compliant with the protocol spec.

[PATCH] USB: Add USB_QUIRK_NO_LPM quirk for sony xperia xz1 smartphone

by Mathias Nyman

The fastboot tool for communicating with Android bootloaders does not work reliably with this device if USB 2 Link Power Management (LPM) is enabled. Various fastboot commands are affected, including the following, which usually reproduces the problem within two tries: fastboot getvar kernel getvar:kernel FAILED (remote: 'GetVar Variable Not found') This issue was hidden on many systems up until commit 63a1f8454962 ("xhci: stored cached port capability values in one place") as the xhci driver failed to detect USB 2 LPM support if USB 3 ports were listed before USB 2 ports in the "supported protocol capabilities". Adding the quirk resolves the issue. No drawbacks are expected since the device uses different USB product IDs outside of fastboot mode, and since fastboot commands worked before, until LPM was enabled on the tested system by the aforementioned commit. Based on a patch from Forest <forestix(a)nom.one> from which most of the code and commit message is taken.

[PATCH v2] ASoC: SOF: ipc4-topology: Harden loops for looking up ALH copiers

by Peter Ujfalusi

Other, non DAI copier widgets could have the same stream name (sname) as the ALH copier and in that case the copier->data is NULL, no alh_data is attached, which could lead to NULL pointer dereference. We could check for this NULL pointer in sof_ipc4_prepare_copier_module() and avoid the crash, but a similar loop in sof_ipc4_widget_setup_comp_dai() will miscalculate the ALH device count, causing broken audio. The correct fix is to harden the matching logic by making sure that the 1. widget is a DAI widget - so dai = w->private is valid 2. the dai (and thus the copier) is ALH copier Fixes: a150345aa758 ("ASoC: SOF: ipc4-topology: add SoundWire/ALH aggregation support") Reported-by: Seppo Ingalsuo <seppo.ingalsuo(a)linux.intel.com> Link: https://github.com/thesofproject/sof/pull/9652 Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)linux.intel.com> Reviewed-by: Liam Girdwood <liam.r.girdwood(a)intel.com> Reviewed-by: Ranjani Sridharan <ranjani.sridharan(a)linux.intel.com> Reviewed-by: Bard Liao <yung-chuan.liao(a)linux.intel.com> --- Hi, Changes since v1: - correct SHA in Fixes tag Regards, Peter sound/soc/sof/ipc4-topology.c | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/sound/soc/sof/ipc4-topology.c b/sound/soc/sof/ipc4-topology.c index c04c62478827..6d5cda813e48 100644 --- a/sound/soc/sof/ipc4-topology.c +++ b/sound/soc/sof/ipc4-topology.c @@ -765,10 +765,16 @@ static int sof_ipc4_widget_setup_comp_dai(struct snd_sof_widget *swidget) } list_for_each_entry(w, &sdev->widget_list, list) { - if (w->widget->sname && + struct snd_sof_dai *alh_dai; + + if (!WIDGET_IS_DAI(w->id) || !w->widget->sname || strcmp(w->widget->sname, swidget->widget->sname)) continue; + alh_dai = w->private; + if (alh_dai->type != SOF_DAI_INTEL_ALH) + continue; + blob->alh_cfg.device_count++; } @@ -2061,11 +2067,13 @@ sof_ipc4_prepare_copier_module(struct snd_sof_widget *swidget, list_for_each_entry(w, &sdev->widget_list, list) { u32 node_type; - if (w->widget->sname && + if (!WIDGET_IS_DAI(w->id) || !w->widget->sname || strcmp(w->widget->sname, swidget->widget->sname)) continue; dai = w->private; + if (dai->type != SOF_DAI_INTEL_ALH) + continue; alh_copier = (struct sof_ipc4_copier *)dai->private; alh_data = &alh_copier->data; node_type = SOF_IPC4_GET_NODE_TYPE(alh_data->gtw_cfg.node_id); -- 2.48.1

[PATCH 0/8] KVM: arm64: FPSIMD/SVE/SME fixes

by Mark Rutland

These patches fix some isuses with the way KVM manages FPSIMD/SVE?SME state. The series supersedes my earlier attempt at fixing the host SVE state corruption issue: https://lore.kernel.org/linux-arm-kernel/20250121100026.3974971-1-mark.rutl… Patch 1 addreses the host SVE state corruption issue by always saving and unbinding the host state when loading a vCPU, as discussed on the earlier patch: https://lore.kernel.org/linux-arm-kernel/Z4--YuG5SWrP_pW7@J2N7QTR9R3/ https://lore.kernel.org/linux-arm-kernel/86plkful48.wl-maz@kernel.org/ Patches 2 to 4 remove code made redundant by patch 1. These probably warrant backporting along with patch 1 as there is some historical brokenness in the code they remove. Patches 5 to 7 are preparatory refactoring for patch 8, and are not intended to have any functional impact. Patch 8 addreses some mismanagement of ZCR_EL{1,2} which can result in the host VMM unexpectedly receiving a SIGKILL. To fix this, we eagerly swith ZCR_EL{1,2} at guest<->host transitions, as discussed on another series: https://lore.kernel.org/linux-arm-kernel/Z4pAMaEYvdLpmbg2@J2N7QTR9R3/ https://lore.kernel.org/linux-arm-kernel/86o6zzukwr.wl-maz@kernel.org/ https://lore.kernel.org/linux-arm-kernel/Z5Dc-WMu2azhTuMn@J2N7QTR9R3/ The end result is that KVM loses ~100 lines of code, and becomes a bit simpler to reaason about. I've pushed these patches (with some additional debug patches that can be used for testing) to the arm64-kvm-fpsimd-fixes-20250204 tag on my kernel.org repo: https://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git/ git://git.kernel.org/pub/scm/linux/kernel/git/mark/linux.git I've given this some basic testing on a virtual platform, booting a host and a guest with and without constraining the guet's max SVE VL, with: * kvm_arm.mode=vhe * kvm_arm.mode=nvhe * kvm_arm.mode=protected (IIUC this will default to hVHE) Any additional testing would be much appreciated.

[PATCH v1 01/16] mm: hugetlb: Add huge page size param to huge_ptep_get_and_clear()

by Ryan Roberts

In order to fix a bug, arm64 needs to be told the size of the huge page for which the huge_pte is being set in huge_ptep_get_and_clear(). Provide for this by adding an `unsigned long sz` parameter to the function. This follows the same pattern as huge_pte_clear() and set_huge_pte_at(). This commit makes the required interface modifications to the core mm as well as all arches that implement this function (arm64, loongarch, mips, parisc, powerpc, riscv, s390, sparc). The actual arm64 bug will be fixed in a separate commit.

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

by Chen-Yu Tsai

From: Chen-Yu Tsai <wens(a)csie.org> The DWMAC 1000 DMA capabilities register does not provide actual FIFO sizes, nor does the driver really care. If they are not provided via some other means, the driver will work fine, only disallowing changing the MTU setting. The recent commit 8865d22656b4 ("net: stmmac: Specify hardware capability value when FIFO size isn't specified") changed this by requiring the FIFO sizes to be provided, breaking devices that were working just fine. Provide the FIFO sizes through the driver's platform data, to not only fix the breakage, but also enable MTU changes. The FIFO sizes are confirmed to be the same across RK3288, RK3328, RK3399 and PX30, based on their respective manuals. It is likely that Rockchip synthesized their DWMAC 1000 with the same parameters on all their chips that have it. Fixes: eaf4fac47807 ("net: stmmac: Do not accept invalid MTU values") Fixes: 8865d22656b4 ("net: stmmac: Specify hardware capability value when FIFO size isn't specified") Cc: <stable(a)vger.kernel.org> Signed-off-by: Chen-Yu Tsai <wens(a)csie.org> --- The reason for stable inclusion is not to fix the device breakage (which only broke in v6.14-rc1), but to provide the values so that MTU changes can work in older kernels.

[PATCH v2] Documentation/no_hz: Remove description that states boot CPU cannot be nohz_full

by Krishanth Jagaduri via B4 Relay

From: Oleg Nesterov <oleg(a)redhat.com> sched/isolation: Prevent boot crash when the boot CPU is nohz_full [ Upstream commit 5097cbcb38e6e0d2627c9dde1985e91d2c9f880e ] Documentation/timers/no_hz.rst states that the "nohz_full=" mask must not include the boot CPU, which is no longer true after: commit 08ae95f4fd3b ("nohz_full: Allow the boot CPU to be nohz_full"). However after: aae17ebb53cd ("workqueue: Avoid using isolated cpus' timers on queue_delayed_work") the kernel will crash at boot time in this case; housekeeping_any_cpu() returns an invalid CPU number until smp_init() brings the first housekeeping CPU up. Change housekeeping_any_cpu() to check the result of cpumask_any_and() and return smp_processor_id() in this case. This is just the simple and backportable workaround which fixes the symptom, but smp_processor_id() at boot time should be safe at least for type == HK_TYPE_TIMER, this more or less matches the tick_do_timer_boot_cpu logic. There is no worry about cpu_down(); tick_nohz_cpu_down() will not allow to offline tick_do_timer_cpu (the 1st online housekeeping CPU).

When trying LTS kernels between 5.4 and 6.6, we noticed we could use boot CPU as nohz_full but the information in the document was misleading. This was fixed upstream by commit 5097cbcb38e6 ("sched/isolation: Prevent boot crash when the boot CPU is nohz_full").

[PATCH net] selftests: mptcp: connect: -f: no reconnect

by Matthieu Baerts (NGI0)

The '-f' parameter is there to force the kernel to emit MPTCP FASTCLOSE by closing the connection with unread bytes in the receive queue. The xdisconnect() helper was used to stop the connection, but it does more than that: it will shut it down, then wait before reconnecting to the same address. This causes the mptcp_join's "fastclose test" to fail all the time. This failure is due to a recent change, with commit 218cc166321f ("selftests: mptcp: avoid spurious errors on disconnect"), but that went unnoticed because the test is currently ignored. The recent modification only shown an existing issue: xdisconnect() doesn't need to be used here, only the shutdown() part is needed.

[PATCH] usb: roles: cache usb roles received during switch registration

by Elson Roy Serrao

The role switch registration and set_role() can happen in parallel as they are invoked independent of each other. There is a possibility that a driver might spend significant amount of time in usb_role_switch_register() API due to the presence of time intensive operations like component_add() which operate under common mutex. This leads to a time window after allocating the switch and before setting the registered flag where the set role notifications are dropped.

[PATCH] soc: qcom: mark pd-mapper as broken

by Johan Hovold

When using the in-kernel pd-mapper on x1e80100, client drivers often fail to communicate with the firmware during boot, which specifically breaks battery and USB-C altmode notifications. This has been observed to happen on almost every second boot (41%) but likely depends on probe order: pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to send altmode request: 0x10 (-125) pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to request altmode notifications: -125 ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI read request: -125 qcom_battmgr.pmic_glink_power_supply pmic_glink.power-supply.0: failed to request power notifications In the same setup audio also fails to probe albeit much more rarely: PDR: avs/audio get domain list txn wait failed: -110 PDR: service lookup for avs/audio failed: -110 Chris Lew has provided an analysis and is working on a fix for the ECANCELED (125) errors, but it is not yet clear whether this will also address the audio regression. Even if this was first observed on x1e80100 there is currently no reason to believe that these issues are specific to that platform. Disable the in-kernel pd-mapper for now, and make sure to backport this to stable to prevent users and distros from migrating away from the user-space service.

[PATCH v2] scsi: core: Do not retry I/Os during depopulation

by Igor Pylypiv

Fail I/Os instead of retry to prevent user space processes from being blocked on the I/O completion for several minutes. Retrying I/Os during "depopulation in progress" or "depopulation restore in progress" results in a continuous retry loop until the depopulation completes or until the I/O retry loop is aborted due to a timeout by the scsi_cmd_runtime_exceeced(). Depopulation is slow and can take 24+ hours to complete on 20+ TB HDDs. Most I/Os in the depopulation retry loop end up taking several minutes before returning the failure to user space.

[PATCH v2] mm,madvise,hugetlb: check for 0-length range after end address adjustment

by Ricardo Cañuelo Navarro

Add a sanity check to madvise_dontneed_free() to address a corner case in madvise where a race condition causes the current vma being processed to be backed by a different page size. During a madvise(MADV_DONTNEED) call on a memory region registered with a userfaultfd, there's a period of time where the process mm lock is temporarily released in order to send a UFFD_EVENT_REMOVE and let userspace handle the event. During this time, the vma covering the current address range may change due to an explicit mmap done concurrently by another thread. If, after that change, the memory region, which was originally backed by 4KB pages, is now backed by hugepages, the end address is rounded down to a hugepage boundary to avoid data loss (see "Fixes" below). This rounding may cause the end address to be truncated to the same address as the start. Make this corner case follow the same semantics as in other similar cases where the requested region has zero length (ie. return 0). This will make madvise_walk_vmas() continue to the next vma in the range (this time holding the process mm lock) which, due to the prev pointer becoming stale because of the vma change, will be the same hugepage-backed vma that was just checked before. The next time madvise_dontneed_free() runs for this vma, if the start address isn't aligned to a hugepage boundary, it'll return -EINVAL, which is also in line with the madvise api. From userspace perspective, madvise() will return EINVAL because the start address isn't aligned according to the new vma alignment requirements (hugepage), even though it was correctly page-aligned when the call was issued.

Now cow_file_range() returned -ENOSPC. - btrfs_run_delalloc_range() do error cleanup <<< ROOT CAUSE Call btrfs_cleanup_ordered_extents() with locked folio 1536K and range [1568K, 1636K) Function btrfs_cleanup_ordered_extents() normally needs to skip the ranges inside the folio, as it will normally be cleaned up by extent_writepage(). Such split error handling is already problematic in the first place. What's worse is the folio range skipping itself, which is not taking subpage cases into consideration at all, it will only skip the range if the page start >= the range start. In our case, the page start < the range start, since for subpage cases we can have delalloc ranges inside the folio but not covering the folio. So it doesn't skip the page range at all. This means all the ordered extents, both [1568K, 1584K) and [1584K, 1596K) will be marked as IOERR. And these two ordered extents have no more pending ios, they are marked finished, and *QUEUED* to be deleted from the io tree. - extent_writepage() do error cleanup Call btrfs_mark_ordered_io_finished() for the range [1536K, 1600K). Although ranges [1568K, 1584K) and [1584K, 1596K) are finished, the deletion from io tree is async, it may or may not happen at this time. If the ranges have not yet been removed, we will do double cleaning on those ranges, triggering the above ordered extent warnings. In theory there are other bugs, like the cleanup in extent_writepage() can cause double accounting on ranges that are submitted asynchronously (compression for example). But that's much harder to trigger because normally we do not mix regular and compression delalloc ranges. [FIX] The folio range split is already buggy and not subpage compatible, it was introduced a long time ago where subpage support was not even considered. So instead of splitting the ordered extents cleanup into the folio range and out of folio range, do all the cleanup inside writepage_delalloc(). - Pass @NULL as locked_folio for btrfs_cleanup_ordered_extents() in btrfs_run_delalloc_range() - Skip the btrfs_cleanup_ordered_extents() if writepage_delalloc() failed So all ordered extents are only cleaned up by btrfs_run_delalloc_range(). - Handle the ranges that already have ordered extents allocated If part of the folio already has ordered extent allocated, and btrfs_run_delalloc_range() failed, we also need to cleanup that range. Now we have a concentrated error handling for ordered extents during btrfs_run_delalloc_range().

Now cow_file_range() returned -ENOSPC. - btrfs_run_delalloc_range() do error cleanup <<< ROOT CAUSE Call btrfs_cleanup_ordered_extents() with locked folio 1536K and range [1568K, 1636K) Function btrfs_cleanup_ordered_extents() normally needs to skip the ranges inside the folio, as it will normally be cleaned up by extent_writepage(). Such split error handling is already problematic in the first place. What's worse is the folio range skipping itself, which is not taking subpage cases into consideration at all, it will only skip the range if the page start >= the range start. In our case, the page start < the range start, since for subpage cases we can have delalloc ranges inside the folio but not covering the folio. So it doesn't skip the page range at all. This means all the ordered extents, both [1568K, 1584K) and [1584K, 1596K) will be marked as IOERR. And these two ordered extents have no more pending ios, they are marked finished, and *QUEUED* to be deleted from the io tree. - extent_writepage() do error cleanup Call btrfs_mark_ordered_io_finished() for the range [1536K, 1600K). Although ranges [1568K, 1584K) and [1584K, 1596K) are finished, the deletion from io tree is async, it may or may not happen at this time. If the ranges have not yet been removed, we will do double cleaning on those ranges, triggering the above ordered extent warnings. In theory there are other bugs, like the cleanup in extent_writepage() can cause double accounting on ranges that are submitted asynchronously (compression for example). But that's much harder to trigger because normally we do not mix regular and compression delalloc ranges. [FIX] The folio range split is already buggy and not subpage compatible, it was introduced a long time ago where subpage support was not even considered. So instead of splitting the ordered extents cleanup into the folio range and out of folio range, do all the cleanup inside writepage_delalloc(). - Pass @NULL as locked_folio for btrfs_cleanup_ordered_extents() in btrfs_run_delalloc_range() - Skip the btrfs_cleanup_ordered_extents() if writepage_delalloc() failed So all ordered extents are only cleaned up by btrfs_run_delalloc_range(). - Handle the ranges that already have ordered extents allocated If part of the folio already has ordered extent allocated, and btrfs_run_delalloc_range() failed, we also need to cleanup that range. Now we have a concentrated error handling for ordered extents during btrfs_run_delalloc_range().

Now cow_file_range() returned -ENOSPC. - btrfs_run_delalloc_range() do error cleanup <<< ROOT CAUSE Call btrfs_cleanup_ordered_extents() with locked folio 1536K and range [1568K, 1636K) Function btrfs_cleanup_ordered_extents() normally needs to skip the ranges inside the folio, as it will normally be cleaned up by extent_writepage(). Such split error handling is already problematic in the first place. What's worse is the folio range skipping itself, which is not taking subpage cases into consideration at all, it will only skip the range if the page start >= the range start. In our case, the page start < the range start, since for subpage cases we can have delalloc ranges inside the folio but not covering the folio. So it doesn't skip the page range at all. This means all the ordered extents, both [1568K, 1584K) and [1584K, 1596K) will be marked as IOERR. And these two ordered extents have no more pending ios, they are marked finished, and *QUEUED* to be deleted from the io tree. - extent_writepage() do error cleanup Call btrfs_mark_ordered_io_finished() for the range [1536K, 1600K). Although ranges [1568K, 1584K) and [1584K, 1596K) are finished, the deletion from io tree is async, it may or may not happen at this time. If the ranges have not yet been removed, we will do double cleaning on those ranges, triggering the above ordered extent warnings. In theory there are other bugs, like the cleanup in extent_writepage() can cause double accounting on ranges that are submitted asynchronously (compression for example). But that's much harder to trigger because normally we do not mix regular and compression delalloc ranges. [FIX] The folio range split is already buggy and not subpage compatible, it was introduced a long time ago where subpage support was not even considered. So instead of splitting the ordered extents cleanup into the folio range and out of folio range, do all the cleanup inside writepage_delalloc(). - Pass @NULL as locked_folio for btrfs_cleanup_ordered_extents() in btrfs_run_delalloc_range() - Skip the btrfs_cleanup_ordered_extents() if writepage_delalloc() failed So all ordered extents are only cleaned up by btrfs_run_delalloc_range(). - Handle the ranges that already have ordered extents allocated If part of the folio already has ordered extent allocated, and btrfs_run_delalloc_range() failed, we also need to cleanup that range. Now we have a concentrated error handling for ordered extents during btrfs_run_delalloc_range().

Now cow_file_range() returned -ENOSPC. - btrfs_run_delalloc_range() do error cleanup <<< ROOT CAUSE Call btrfs_cleanup_ordered_extents() with locked folio 1536K and range [1568K, 1636K) Function btrfs_cleanup_ordered_extents() normally needs to skip the ranges inside the folio, as it will normally be cleaned up by extent_writepage(). Such split error handling is already problematic in the first place. What's worse is the folio range skipping itself, which is not taking subpage cases into consideration at all, it will only skip the range if the page start >= the range start. In our case, the page start < the range start, since for subpage cases we can have delalloc ranges inside the folio but not covering the folio. So it doesn't skip the page range at all. This means all the ordered extents, both [1568K, 1584K) and [1584K, 1596K) will be marked as IOERR. And these two ordered extents have no more pending ios, they are marked finished, and *QUEUED* to be deleted from the io tree. - extent_writepage() do error cleanup Call btrfs_mark_ordered_io_finished() for the range [1536K, 1600K). Although ranges [1568K, 1584K) and [1584K, 1596K) are finished, the deletion from io tree is async, it may or may not happen at this time. If the ranges have not yet been removed, we will do double cleaning on those ranges, triggering the above ordered extent warnings. In theory there are other bugs, like the cleanup in extent_writepage() can cause double accounting on ranges that are submitted asynchronously (compression for example). But that's much harder to trigger because normally we do not mix regular and compression delalloc ranges. [FIX] The folio range split is already buggy and not subpage compatible, it was introduced a long time ago where subpage support was not even considered. So instead of splitting the ordered extents cleanup into the folio range and out of folio range, do all the cleanup inside writepage_delalloc(). - Pass @NULL as locked_folio for btrfs_cleanup_ordered_extents() in btrfs_run_delalloc_range() - Skip the btrfs_cleanup_ordered_extents() if writepage_delalloc() failed So all ordered extents are only cleaned up by btrfs_run_delalloc_range(). - Handle the ranges that already have ordered extents allocated If part of the folio already has ordered extent allocated, and btrfs_run_delalloc_range() failed, we also need to cleanup that range. Now we have a concentrated error handling for ordered extents during btrfs_run_delalloc_range().

Now cow_file_range() returned -ENOSPC. - btrfs_run_delalloc_range() do error cleanup <<< ROOT CAUSE Call btrfs_cleanup_ordered_extents() with locked folio 1536K and range [1568K, 1636K) Function btrfs_cleanup_ordered_extents() normally needs to skip the ranges inside the folio, as it will normally be cleaned up by extent_writepage(). Such split error handling is already problematic in the first place. What's worse is the folio range skipping itself, which is not taking subpage cases into consideration at all, it will only skip the range if the page start >= the range start. In our case, the page start < the range start, since for subpage cases we can have delalloc ranges inside the folio but not covering the folio. So it doesn't skip the page range at all. This means all the ordered extents, both [1568K, 1584K) and [1584K, 1596K) will be marked as IOERR. And these two ordered extents have no more pending ios, they are marked finished, and *QUEUED* to be deleted from the io tree. - extent_writepage() do error cleanup Call btrfs_mark_ordered_io_finished() for the range [1536K, 1600K). Although ranges [1568K, 1584K) and [1584K, 1596K) are finished, the deletion from io tree is async, it may or may not happen at this time. If the ranges have not yet been removed, we will do double cleaning on those ranges, triggering the above ordered extent warnings. In theory there are other bugs, like the cleanup in extent_writepage() can cause double accounting on ranges that are submitted asynchronously (compression for example). But that's much harder to trigger because normally we do not mix regular and compression delalloc ranges. [FIX] The folio range split is already buggy and not subpage compatible, it was introduced a long time ago where subpage support was not even considered. So instead of splitting the ordered extents cleanup into the folio range and out of folio range, do all the cleanup inside writepage_delalloc(). - Pass @NULL as locked_folio for btrfs_cleanup_ordered_extents() in btrfs_run_delalloc_range() - Skip the btrfs_cleanup_ordered_extents() if writepage_delalloc() failed So all ordered extents are only cleaned up by btrfs_run_delalloc_range(). - Handle the ranges that already have ordered extents allocated If part of the folio already has ordered extent allocated, and btrfs_run_delalloc_range() failed, we also need to cleanup that range. Now we have a concentrated error handling for ordered extents during btrfs_run_delalloc_range().

This should be very rare, as submit_one_sector() only fails when we failed to grab the extent map, and such extent map should exist inside the memory and has been pinned. [CAUSE] For example we have the following folio layout: 0 4K 32K 48K 60K 64K |//| |//////| |///| Where |///| is the dirty range we need to writeback. The 3 different dirty ranges are submitted for regular COW. Now we hit the following sequence: - submit_one_sector() returned 0 for [0, 4K) - submit_one_sector() returned 0 for [32K, 48K) - submit_one_sector() returned error for [60K, 64K) - btrfs_mark_ordered_io_finished() called for the whole folio This will mark the following ranges as finished: * [0, 4K) * [32K, 48K) Both ranges have their IO already submitted, this cleanup will lead to double accounting. * [60K, 64K) That's the correct cleanup. The only good news is, this error is only theoretical, as the target extent map is always pinned, thus we should directly grab it from memory, other than reading it from the disk.

This should be very rare, as submit_one_sector() only fails when we failed to grab the extent map, and such extent map should exist inside the memory and has been pinned. [CAUSE] For example we have the following folio layout: 0 4K 32K 48K 60K 64K |//| |//////| |///| Where |///| is the dirty range we need to writeback. The 3 different dirty ranges are submitted for regular COW. Now we hit the following sequence: - submit_one_sector() returned 0 for [0, 4K) - submit_one_sector() returned 0 for [32K, 48K) - submit_one_sector() returned error for [60K, 64K) - btrfs_mark_ordered_io_finished() called for the whole folio This will mark the following ranges as finished: * [0, 4K) * [32K, 48K) Both ranges have their IO already submitted, this cleanup will lead to double accounting. * [60K, 64K) That's the correct cleanup. The only good news is, this error is only theoretical, as the target extent map is always pinned, thus we should directly grab it from memory, other than reading it from the disk. [FIX] Instead of calling btrfs_mark_ordered_io_finished() for the whole folio range, which can touch ranges we should not touch, instead move the error handling inside extent_writepage_io(). So that we can cleanup exact sectors that ought to be submitted but failed. This provides much more accurate cleanup, avoiding the double accounting.

[PATCH] ima: Reset IMA_NONACTION_RULE_FLAGS after post_setattr

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> Commit 0d73a55208e9 ("ima: re-introduce own integrity cache lock") mistakenly reverted the performance improvement introduced in commit 42a4c603198f0 ("ima: fix ima_inode_post_setattr"). The unused bit mask was subsequently removed by commit 11c60f23ed13 ("integrity: Remove unused macro IMA_ACTION_RULE_FLAGS"). Restore the performance improvement by introducing the new mask IMA_NONACTION_RULE_FLAGS, equal to IMA_NONACTION_FLAGS without IMA_NEW_FILE, which is not a rule-specific flag. Finally, reset IMA_NONACTION_RULE_FLAGS instead of IMA_NONACTION_FLAGS in process_measurement(), if the IMA_CHANGE_ATTR atomic flag is set (after file metadata modification). With this patch, new files for which metadata were modified while they are still open, can be reopened before the last file close (when security.ima is written), since the IMA_NEW_FILE flag is not cleared anymore. Otherwise, appraisal fails because security.ima is missing (files with IMA_NEW_FILE set are an exception).

Hello, we are seeing broken CPU PSI metrics across our infrastructure running 6.12, with messages like "psi: inconsistent task state! task=1831:hackbench cpu=8 psi_flags=14 clear=0 set=4" in dmesg. I believe commit 7d9da040575b343085287686fa902a5b2d43c7ca might fix this issue. psi: Fix race when task wakes up before psi_sched_switch() adjusts flags Thanks Paul

[PATCH V2 1/1] x86/tdx: Route safe halt execution via tdx_safe_halt()

by Vishal Annapurve

Direct HLT instruction execution causes #VEs for TDX VMs which is routed to hypervisor via tdvmcall. This process renders HLT instruction execution inatomic, so any preceding instructions like STI/MOV SS will end up enabling interrupts before the HLT instruction is routed to the hypervisor. This creates scenarios where interrupts could land during HLT instruction emulation without aborting halt operation leading to idefinite halt wait times. Commit bfe6ed0c6727 ("x86/tdx: Add HLT support for TDX guests") already upgraded x86_idle() to invoke tdvmcall to avoid such scenarios, but it didn't cover pv_native_safe_halt() which can be invoked using raw_safe_halt() from call sites like acpi_safe_halt(). raw_safe_halt() also returns with interrupts enabled so upgrade tdx_safe_halt() to enable interrupts by default and ensure that paravirt safe_halt() executions invoke tdx_safe_halt(). Earlier x86_idle() is now handled via tdx_idle() which simply invokes tdvmcall while preserving irq state. To avoid future call sites which cause HLT instruction emulation with irqs enabled, add a warn and fail the HLT instruction emulation.
