3 daysUSB: gadgetfs: do not WARN about excessively large memory allocationsZi Yan
GadgetFS passes an excessively large user input len to kmalloc and kmalloc gives a WARN (see below for details). Suppress it by passing __GFP_NOWARN to kmalloc used by both ep_write_iter() and ep_read_iter(). Follow the same method as commit 4f2629ea67e72 ("USB: usbfs: Don't WARN about excessively large memory allocations"). kmalloc is used to allocate physically contiguous memory for kernel allocations. For requests larger than KMALLOC_MAX_CACHE_SIZE, kmalloc uses the page allocator and can only support up to KMALLOC_MAX_SIZE. For request sizes bigger than KMALLOC_MAX_SIZE, the page allocator can emit a WARN because kmalloc allocates an order greater than MAX_PAGE_ORDER.

4 daystreewide: refresh kmalloc_obj() conversionsKees Cook
This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

speedtch_upload_firmware() allocates a temporary buffer used to feed the firmware to the device. This buffer can be allocated with kmalloc() as there's nothing special about it to go directly to the page allocator. kmalloc() provides a better API that does not require ugly casts and kfree() does not need to know the size of the freed object. Performance difference between kmalloc() and __get_free_pages() is not measurable as both allocators take an object/page from a per-CPU list for fast path allocations. For the slow path the performance is anyway determined by the amount of reclaim involved rather than by what allocator is used. Replace use of __get_free_page() with kmalloc() and free_page() with kfree().

7 daysscsi: core: Drop Scsi_Host.default_lockJohn Garry
Back in the 2.6.xx days, it was possible to for low-level drivers to set the shost lock pointer. That is why there is a default lock and a pointer to the shost lock. However, support for this has long been removed, so drop Scsi_Host.default_lock and make Scsi_Host.host_lock as the actual lock. Getting the address of embedded host_lock structure just requires adding a fixed offset value to the shost pointer. However, getting the value of the host_lock pointer requires loading from a fixed offset to the shost pointer. The latter should be very slightly slower, which is relevant as this lock is used a lot throughout the core code and drivers.

7 daysusb: typec: qcom-pmic-typec: drain cc_debounce_dwork if port_start() failsFan Wu
cc_debounce_dwork can be queued before port_start() fails: tcpm_register_port() runs first, and its state machine may invoke set_cc() or start_toggling() from the TCPM worker. The error path then calls tcpm_unregister_port(), whose worker flush may queue the delayed work before devres frees pmic_typec_port. Disable and drain the delayed work directly at port_start()'s error exit. Do not use port_stop() for this path: its IRQs use IRQF_NO_AUTOEN and are enabled only after a successful port_start(). This issue was found by an in-house static analysis tool.

7 daysusb: typec: qcom-pmic-typec: disable cc_debounce_dwork on stopFan Wu
cc_debounce_dwork is queued from the set_cc() and start_toggling() callbacks, which run from TCPM's kthread worker. port_stop() returns before tcpm_unregister_port() destroys that worker. Flushing the worker during unregister may therefore run a callback which queues the delayed work after port_stop() has returned. The delayed work can then run after devres has freed pmic_typec_port. Use disable_delayed_work_sync() in port_stop() to cancel a pending instance and prevent the TCPM callbacks from queueing another one. This issue was found by an in-house static analysis tool.

7 daysusb: gadget: fix null pointer dereference in usb_put_function_instance()Jeffin Philip
usb_put_function_instance() attempts to dereference fd inside fi struct to get mod in uvc_alloc_inst() error path.

7 daysusb: cdnsp: fix wakeup from S3 after controller context lossPawel Laszczak
CDNSP controller may lose its runtime register programming across S3 suspend/resume, depending on SoC power domain configuration. After resume the operational and interrupter registers may contain reset values, which prevents the gadget side from recovering correctly and breaks wakeup from S3. Fix this by detecting whether the controller lost its register context after resume and handling both cases: - If context was lost (CFG_3XPORT_U1_PIPE_CLK_GATE_EN set or power lost): reset the controller and reprogram the state required for normal operation, including the command ring, DCBAA pointer, doorbell base, event ring, ERST base/size and event ring dequeue pointer. - If context was retained: restart the controller directly without reprogramming registers. Issue a wakeup if the link was in U3 before suspend. Move the basic controller register programming out of the one-time memory initialization path and make it reusable from the resume path. Also separate ring allocation from ring initialization so that rings can be reinitialized without reallocating DMA memory. Always perform the full suspend sequence regardless of the current link state. Previously, if the device was already in U3, the suspend callback returned early without stopping the controller, which could lead to commands being issued on a disabled slot during resume.

ene_ub6250_probe() calls usb_stor_probe2(), which starts the usb-storage infrastructure and schedules the delayed scan work. The driver then calls ene_get_card_type(), which sends an ENE command through ene_send_scsi_cmd() and the usb-storage bulk transfer helpers. Both the delayed scan work, through usb_stor_Bulk_max_lun(), and ene_get_card_type() use us->current_urb. The scan work serializes this access with us->dev_mutex, but the ENE card-type probe does not. If the scan work runs while ene_get_card_type() is still using us->current_urb, usb_submit_urb() warns that the URB is already active. Serialize ene_get_card_type() with us->dev_mutex, matching the locking used by the scan path.

7 daysusb: gadget: midi2: Fix null-pointer dereference in f_midi2_free_ep_reqsAleksandr Nogikh
A null-pointer dereference occurs in f_midi2_free_ep_reqs() when attempting to clean up an endpoint that was never initialized. When configuring the MIDI 2.0 gadget via configfs and setting the block direction to SNDRV_UMP_DIR_INPUT, the initialization of the midi1_ep_out endpoint is explicitly skipped during the gadget bind phase (f_midi2_bind()). As a result, the usb_ep->card field remains NULL. Later, when the host sets the alternate setting, f_midi2_set_alt() unconditionally stops both the IN and OUT endpoints by calling f_midi2_stop_eps(), which in turn calls f_midi2_free_ep_reqs() for both endpoints. When f_midi2_free_ep_reqs() is called for the uninitialized midi1_ep_out, it attempts to dereference usb_ep->card to determine the number of requests to free, leading to a crash. Fix this by using usb_ep->num_reqs instead of usb_ep->card->info.num_reqs in f_midi2_free_ep_reqs(). usb_ep->num_reqs is correctly set during f_midi2_init_ep() and remains 0 if the endpoint was never initialized, safely avoiding the loop. For consistency, apply the same change to f_midi2_alloc_ep_reqs().

7 daysusb: dwc3: clear forceRM when issuing EndTransferElson Serrao
The forceRM bit of the DEPCMD register controls the behavior of the EndTransfer command used to stop an active transfer. Older DWC3 programming guide revisions recommended setting forceRM=1 when issuing EndTransfer. Newer programming guide revisions recommend issuing EndTransfer with forceRM cleared. With forceRM=1 on DWC_usb31 v2.00a and v2.10a controllers, a transfer aborted through the ep_dequeue path was observed to remain active after EndTransfer completion. A subsequent StartTransfer issued on the same endpoint triggered writes associated with the aborted transfer. This resulted in an SMMU fault because the transfer buffer had already been unmapped during EndTransfer command-completion cleanup. Using forceRM=0 eliminates the issue. Although older DWC3 programming guide revisions recommended setting forceRM=1, no issues are known from using forceRM=0.

7 daysusb: typec: mux: Fix typec_switch_match()Marek Vasut
The fwnode_typec_switch_get() sporadically returns NULL instead of an -EPROBE_DEFER for orientation-switch described in DT. This makes it impossible to discern whether the DT does describe an orientation-switch which did not probe yet, or whether the DT does not describe the switch. This happens with gpio-sbu-mux connected to an I2C GPIO expander. The class_find_device() on typec_switch_match() may return NULL in case the mux did not probe just yet early on boot. The sw_devs[] array can be empty on boot as well. If these two conditions occur, then the conditional if (to_typec_switch_dev(dev) == sw_devs[i]) evaluates to true and the match function returns NULL, which propagates to fwnode_typec_switch_get() which makes it look as if the orientation-switch was not described in DT. This is incorrect, because the mux driver will probe a bit later on, but at that point, the caller of fwnode_typec_switch_get() already got the NULL return value. The NULL return value also does not trigger IS_ERR(), therefore the caller driver interprets this as if the orientation-switch is not described in DT, and does not return -EPROBE_DEFER to try again, even if it should. Fix this by checking the class_find_device() return value, and return -EPROBE_DEFER if it is NULL right away. If the return value is not NULL, perform the deduplication test, and if that test passes, consider the return value to be already non-NULL.

7 daysusb: dwc3: qcom: Add support to skip phy management by USB coreKrishna Kurapati
DWC3 driver does manage phys itself sufficiently for Qualcomm platforms. If xhci-skip-phy-init is not set, the HCD core does a phy_init and phy_ exit is done only when roothub is being destroyed. Due to this, during system suspend in host mode, although phy_exit is done by DWC3 core, the init_count on phy is never down to zero since HCD core also did an init. consequently causing phy's exit routine to not be called. Hence, add support to skip phy management by USB core. Some Exynos platforms still do rely on USB core for phy_calibrate calls, hence disable USB core management for Qualcomm platforms only.
