2025-02-14firmware: imx: IMX_SCMI_MISC_DRV should depend on ARCH_MXCGeert Uytterhoeven
The i.MX System Controller Management Interface firmware is only present on Freescale i.MX SoCs. Hence add a dependency on ARCH_MXC, to prevent asking the user about this driver when configuring a kernel without Freescale i.MX platform support.

2025-02-14phy: tegra: xusb: reset VBUS & ID OVERRIDEBH Hsieh
Observed VBUS_OVERRIDE & ID_OVERRIDE might be programmed with unexpected value prior to XUSB PADCTL driver, this could also occur in virtualization scenario. For example, UEFI firmware programs ID_OVERRIDE=GROUNDED to set a type-c port to host mode and keeps the value to kernel. If the type-c port is connected a usb host, below errors can be observed right after usb host mode driver gets probed. The errors would keep until usb role class driver detects the type-c port as device mode and notifies usb device mode driver to set both ID_OVERRIDE and VBUS_OVERRIDE to correct value by XUSB PADCTL driver.

2025-02-14phy: ti: gmii-sel: Do not use syscon helper to build regmapAndrew Davis
The syscon helper device_node_to_regmap() is used to fetch a regmap registered to a device node. It also currently creates this regmap if the node did not already have a regmap associated with it. This should only be used on "syscon" nodes. This driver is not such a device and instead uses device_node_to_regmap() on its own node as a hacky way to create a regmap for itself. This will not work going forward and so we should create our regmap the normal way by defining our regmap_config, fetching our memory resource, then using the normal regmap_init_mmio() function.

2025-02-14fuse: revert back to __readahead_folio() for readaheadJoanne Koong
In commit 3eab9d7bc2f4 ("fuse: convert readahead to use folios"), the logic was converted to using the new folio readahead code, which drops the reference on the folio once it is locked, using an inferred reference on the folio. Previously we held a reference on the folio for the entire duration of the readpages call. This is fine, however for the case for splice pipe responses where we will remove the old folio and splice in the new folio (see fuse_try_move_page()), we assume that there is a reference held on the folio for ap->folios, which is no longer the case. To fix this, revert back to __readahead_folio() which allows us to hold the reference on the folio for the duration of readpages until either we drop the reference ourselves in fuse_readpages_end() or the reference is dropped after it's replaced in the page cache in the splice case. This will fix the UAF bug that was reported.

2025-02-14sched/fair: Refactor can_migrate_task() to elimate loopingI Hsin Cheng
The function "can_migrate_task()" utilize "for_each_cpu_and" with a "if" statement inside to find the destination cpu. It's the same logic to find the first set bit of the result of the bitwise-AND of "env->dst_grpmask", "env->cpus" and "p->cpus_ptr". Refactor it by using "cpumask_first_and_and()" to perform bitwise-AND for "env->dst_grpmask", "env->cpus" and "p->cpus_ptr" and pick the first cpu within the intersection as the destination cpu, so we can elimate the need of looping and multiple times of branch.

2025-02-14sched: Reduce the default slice to avoid tasks getting an extra tickzihan zhou
The old default value for slice is 0.75 msec * (1 + ilog(ncpus)) which means that we have a default slice of: 0.75 for 1 cpu 1.50 up to 3 cpus 2.25 up to 7 cpus 3.00 for 8 cpus and above. For HZ=250 and HZ=100, because of the tick accuracy, the runtime of tasks is far higher than their slice. For HZ=1000 with 8 cpus or more, the accuracy of tick is already satisfactory, but there is still an issue that tasks will get an extra tick because the tick often arrives a little faster than expected. In this case, the task can only wait until the next tick to consider that it has reached its deadline, and will run 1ms longer. vruntime + sysctl_sched_base_slice = deadline |-----------|-----------|-----------|-----------| 1ms 1ms 1ms 1ms ^ ^ ^ ^ tick1 tick2 tick3 tick4(nearly 4ms) There are two reasons for tick error: clockevent precision and the CONFIG_IRQ_TIME_ACCOUNTING/CONFIG_PARAVIRT_TIME_ACCOUNTING. with CONFIG_IRQ_TIME_ACCOUNTING every tick will be less than 1ms, but even without it, because of clockevent precision, tick still often less than 1ms. In order to make scheduling more precise, we changed 0.75 to 0.70, Using 0.70 instead of 0.75 should not change much for other configs and would fix this issue: 0.70 for 1 cpu 1.40 up to 3 cpus 2.10 up to 7 cpus 2.8 for 8 cpus and above. This does not guarantee that tasks can run the slice time accurately every time, but occasionally running an extra tick has little impact.

2025-02-14sched: Cancel the slice protection of the idle entityzihan zhou
A wakeup non-idle entity should preempt idle entity at any time, but because of the slice protection of the idle entity, the non-idle entity has to wait, so just cancel it. This patch is aimed at minimizing the impact of SCHED_IDLE on SCHED_NORMAL. For example, a task with SCHED_IDLE policy that sleeps for 1s and then runs for 3 ms, running cyclictest on the same cpu, has a maximum latency of 3 ms, which is caused by the slice protection of the idle entity. It is unreasonable. With this patch, the cyclictest latency under the same conditions is basically the same on the cpu with idle processes and on empty cpu.

2025-02-14serial: 8250: Fix fifo underflow on flushJohn 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.

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

2025-02-14usb: typec: tcpm: PSSourceOffTimer timeout in PR_Swap enters ERROR_RECOVERYJos Wang
As PD2.0 spec ("6.5.6.2 PSSourceOffTimer"),the PSSourceOffTimer is used by the Policy Engine in Dual-Role Power device that is currently acting as a Sink to timeout on a PS_RDY Message during a Power Role Swap sequence. This condition leads to a Hard Reset for USB Type-A and Type-B Plugs and Error Recovery for Type-C plugs and return to USB Default Operation. Therefore, after PSSourceOffTimer timeout, the tcpm state machine should switch from PR_SWAP_SNK_SRC_SINK_OFF to ERROR_RECOVERY. This can also solve the test items in the USB power delivery compliance test: TEST.PD.PROT.SNK.12 PR_Swap – PSSourceOffTimer Timeout [1] https://usb.org/document-library/usb-power-delivery-compliance-test-specification-0/USB_PD3_CTS_Q4_2025_OR.zip Fixes: f0690a25a140 ("staging: typec: USB Type-C Port Manager (tcpm)") Cc: stable <stable@kernel.org> Signed-off-by: Jos Wang <joswang@lenovo.com> Reviewed-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Tested-by: Amit Sunil Dhamne <amitsd@google.com> Link: https://lore.kernel.org/r/20250213134921.3798-1-joswang1221@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2025-02-14usb: roles: set switch registered flag early onElson 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. Below timeline summarizes this behavior Thread1 | Thread2 usb_role_switch_register() | | | ---> allocate switch | | | ---> component_add() | usb_role_switch_set_role() | | | | | --> Drop role notifications | | since sw->registered | | flag is not set. | | --->Set registered flag.| To avoid this, set the registered flag early on in the switch register API.

2025-02-14usb: core: fix pipe creation for get_bMaxPacketSize0Stefan Eichenberger
When usb_control_msg is used in the get_bMaxPacketSize0 function, the USB pipe does not include the endpoint device number. This can cause failures when a usb hub port is reinitialized after encountering a bad cable connection. As a result, the system logs the following error messages: usb usb2-port1: cannot reset (err = -32) usb usb2-port1: Cannot enable. Maybe the USB cable is bad? usb usb2-port1: attempt power cycle usb 2-1: new high-speed USB device number 5 using ci_hdrc usb 2-1: device descriptor read/8, error -71 The problem began after commit 85d07c556216 ("USB: core: Unite old scheme and new scheme descriptor reads"). There usb_get_device_descriptor was replaced with get_bMaxPacketSize0. Unlike usb_get_device_descriptor, the get_bMaxPacketSize0 function uses the macro usb_rcvaddr0pipe, which does not include the endpoint device number. usb_get_device_descriptor, on the other hand, used the macro usb_rcvctrlpipe, which includes the endpoint device number. By modifying the get_bMaxPacketSize0 function to use usb_rcvctrlpipe instead of usb_rcvaddr0pipe, the issue can be resolved. This change will ensure that the endpoint device number is included in the USB pipe, preventing reinitialization failures. If the endpoint has not set the device number yet, it will still work because the device number is 0 in udev.

2025-02-14usb: dwc3: Fix timeout issue during controller enter/exit from halt stateSelvarasu Ganesan
There is a frequent timeout during controller enter/exit from halt state after toggling the run_stop bit by SW. This timeout occurs when performing frequent role switches between host and device, causing device enumeration issues due to the timeout. This issue was not present when USB2 suspend PHY was disabled by passing the SNPS quirks (snps,dis_u2_susphy_quirk and snps,dis_enblslpm_quirk) from the DTS. However, there is a requirement to enable USB2 suspend PHY by setting of GUSB2PHYCFG.ENBLSLPM and GUSB2PHYCFG.SUSPHY bits when controller starts in gadget or host mode results in the timeout issue. This commit addresses this timeout issue by ensuring that the bits GUSB2PHYCFG.ENBLSLPM and GUSB2PHYCFG.SUSPHY are cleared before starting the dwc3_gadget_run_stop sequence and restoring them after the dwc3_gadget_run_stop sequence is completed.

2025-02-14landlock: Fix non-TCP sockets restrictionMikhail Ivanov
Use sk_is_tcp() to check if socket is TCP in bind(2) and connect(2) hooks. SMC, MPTCP, SCTP protocols are currently restricted by TCP access rights. The purpose of TCP access rights is to provide control over ports that can be used by userland to establish a TCP connection. Therefore, it is incorrect to deny bind(2) and connect(2) requests for a socket of another protocol. However, SMC, MPTCP and RDS implementations use TCP internal sockets to establish communication or even to exchange packets over a TCP connection [1]. Landlock rules that configure bind(2) and connect(2) usage for TCP sockets should not cover requests for sockets of such protocols. These protocols have different set of security issues and security properties, therefore, it is necessary to provide the userland with the ability to distinguish between them (eg. [2]). Control over TCP connection used by other protocols can be achieved with upcoming support of socket creation control [3].

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.

If we receive an initial fragment of size 8 bytes which specifies a wLength of 1 byte (so the reassembled message is supposed to be 9 bytes long), and we then receive a second fragment of size 9 bytes (which is not supposed to happen), we currently wrongly bypass the fragment reassembly code but still pass the pointer to the acm->notification_buffer to acm_process_notification(). Make this less wrong by always going through fragment reassembly when we expect more fragments.

If the first fragment is shorter than struct usb_cdc_notification, we can't calculate an expected_size.

This issue has been present since the beginning of git history; however, it only leads to memory corruption since commit ea2583529cd1 ("cdc-acm: reassemble fragmented notifications"). A mitigating factor is that acm_ctrl_irq() can only execute after userspace has opened /dev/ttyACM*; but if ModemManager is running, ModemManager will do that automatically depending on the USB device's vendor/product IDs and its other interfaces.

2025-02-14iommu/vt-d: Make intel_iommu_drain_pasid_prq() cover faults for RIDLu Baolu
This driver supports page faults on PCI RID since commit <9f831c16c69e> ("iommu/vt-d: Remove the pasid present check in prq_event_thread") by allowing the reporting of page faults with the pasid_present field cleared to the upper layer for further handling. The fundamental assumption here is that the detach or replace operations act as a fence for page faults. This implies that all pending page faults associated with a specific RID or PASID are flushed when a domain is detached or replaced from a device RID or PASID. However, the intel_iommu_drain_pasid_prq() helper does not correctly handle faults for RID. This leads to faults potentially remaining pending in the iommu hardware queue even after the domain is detached, thereby violating the aforementioned assumption.

2025-02-14iommu/amd: Expicitly enable CNTRL.EPHEn bit in resume pathVasant Hegde
With recent kernel, AMDGPU failed to resume after suspend on certain laptop. Sample log: ----------- Nov 14 11:52:19 Thinkbook kernel: iommu ivhd0: AMD-Vi: Event logged [ILLEGAL_DEV_TABLE_ENTRY device=0000:06:00.0 pasid=0x00000 address=0x135300000 flags=0x0080] Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[0]: 7d90000000000003 Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[1]: 0000100103fc0009 Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[2]: 2000000117840013 Nov 14 11:52:19 Thinkbook kernel: AMD-Vi: DTE[3]: 0000000000000000 This is because in resume path, CNTRL[EPHEn] is not set. Fix this by setting CNTRL[EPHEn] to 1 in resume path if EFR[EPHSUP] is set. Note May be better approach is to save the control register in suspend path and restore it in resume path instead of trying to set indivisual bits. We will have separate patch for that.

2025-02-14ALSA: hda: Add error check for snd_ctl_rename_id() in ↵Wentao Liang
snd_hda_create_dig_out_ctls() Check the return value of snd_ctl_rename_id() in snd_hda_create_dig_out_ctls(). Ensure that failures are properly handled. [ Note: the error cannot happen practically because the only error condition in snd_ctl_rename_id() is the missing ID, but this is a rename, hence it must be present. But for the code consistency, it's safer to have always the proper return check -- tiwai ] Fixes: 5c219a340850 ("ALSA: hda: Fix kctl->id initialization") Cc: stable@vger.kernel.org # 6.4+ Signed-off-by: Wentao Liang <vulab@iscas.ac.cn> Link: https://patch.msgid.link/20250213074543.1620-1-vulab@iscas.ac.cn Signed-off-by: Takashi Iwai <tiwai@suse.de>
