[PATCH 0/2] vt: Miscellaneous fixes for keyboard input handling

by Myrrh Periwinkle

This patch series fixes two long standing bugs that when combined results in a ^@ (NUL) sequence being generated on the virtual terminal even when the keyboard mode is set to OFF every suspend/resume cycle on ACPI systems.

This flushing did however trigger new issues on Raspberry Pi 3B+, which doesn't have USB3 ports, and doesn't queue any post resume delayed work. The flushed 'hub->init_work' item is used for several purposes, and is originally initialized with a 'NULL' work function. The work function is also changed on the fly, which may contribute to the issue. Solve this by creating a dedicated delayed work item for post resume work, and flush that delayed work in hub_quiesce() Cc: stable <stable(a)kernel.org> Fixes: a49e1e2e785f ("usb: hub: Fix flushing and scheduling of delayed work that tunes runtime pm") Reported-by: Mark Brown <broonie(a)kernel.org> Closes: https://lore.kernel.org/linux-usb/aF5rNp1l0LWITnEB@finisterre.sirena.org.uk Signed-off-by: Mathias Nyman <mathias.nyman(a)linux.intel.com> Tested-by: Konrad Dybcio <konrad.dybcio(a)oss.qualcomm.com> # SC8280XP CRD Tested-by: Mark Brown <broonie(a)kernel.org> Link: https://lore.kernel.org/r/20250627164348.3982628-2-mathias.nyman@linux.inte… Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> diff --git a/drivers/usb/core/hub.c b/drivers/usb/core/hub.c index 08562711dcf2..3e1215f7a9a0 100644 --- a/drivers/usb/core/hub.c +++ b/drivers/usb/core/hub.c @@ -1074,12 +1074,11 @@ int usb_remove_device(struct usb_device *udev) enum hub_activation_type { HUB_INIT, HUB_INIT2, HUB_INIT3, /* INITs must come first */ - HUB_POST_RESET, HUB_RESUME, HUB_RESET_RESUME, HUB_POST_RESUME, + HUB_POST_RESET, HUB_RESUME, HUB_RESET_RESUME, }; static void hub_init_func2(struct work_struct *ws); static void hub_init_func3(struct work_struct *ws); -static void hub_post_resume(struct work_struct *ws); static void hub_activate(struct usb_hub *hub, enum hub_activation_type type) { @@ -1103,12 +1102,6 @@ static void hub_activate(struct usb_hub *hub, enum hub_activation_type type) goto init3; } - if (type == HUB_POST_RESUME) { - usb_autopm_put_interface_async(to_usb_interface(hub->intfdev)); - hub_put(hub); - return; - } - hub_get(hub); /* The superspeed hub except for root hub has to use Hub Depth @@ -1362,8 +1355,8 @@ static void hub_activate(struct usb_hub *hub, enum hub_activation_type type) usb_autopm_get_interface_no_resume( to_usb_interface(hub->intfdev)); - INIT_DELAYED_WORK(&hub->init_work, hub_post_resume); - queue_delayed_work(system_power_efficient_wq, &hub->init_work, + queue_delayed_work(system_power_efficient_wq, + &hub->post_resume_work, msecs_to_jiffies(USB_SS_PORT_U0_WAKE_TIME)); return; } @@ -1388,9 +1381,10 @@ static void hub_init_func3(struct work_struct *ws) static void hub_post_resume(struct work_struct *ws) { - struct usb_hub *hub = container_of(ws, struct usb_hub, init_work.work); + struct usb_hub *hub = container_of(ws, struct usb_hub, post_resume_work.work); - hub_activate(hub, HUB_POST_RESUME); + usb_autopm_put_interface_async(to_usb_interface(hub->intfdev)); + hub_put(hub); } enum hub_quiescing_type { @@ -1418,7 +1412,7 @@ static void hub_quiesce(struct usb_hub *hub, enum hub_quiescing_type type) /* Stop hub_wq and related activity */ timer_delete_sync(&hub->irq_urb_retry); - flush_delayed_work(&hub->init_work); + flush_delayed_work(&hub->post_resume_work); usb_kill_urb(hub->urb); if (hub->has_indicators) cancel_delayed_work_sync(&hub->leds); @@ -1977,6 +1971,7 @@ static int hub_probe(struct usb_interface *intf, const struct usb_device_id *id) hub->hdev = hdev; INIT_DELAYED_WORK(&hub->leds, led_work); INIT_DELAYED_WORK(&hub->init_work, NULL); + INIT_DELAYED_WORK(&hub->post_resume_work, hub_post_resume); INIT_WORK(&hub->events, hub_event); INIT_LIST_HEAD(&hub->onboard_devs); spin_lock_init(&hub->irq_urb_lock); diff --git a/drivers/usb/core/hub.h b/drivers/usb/core/hub.h index e6ae73f8a95d..9ebc5ef54a32 100644 --- a/drivers/usb/core/hub.h +++ b/drivers/usb/core/hub.h @@ -70,6 +70,7 @@ struct usb_hub { u8 indicator[USB_MAXCHILDREN]; struct delayed_work leds; struct delayed_work init_work; + struct delayed_work post_resume_work; struct work_struct events; spinlock_t irq_urb_lock; struct timer_list irq_urb_retry;

[PATCH] x86/bugs: Fix use of possibly uninit value in amd_check_tsa_microcode()

by Michael Zhivich

Note: I believe this change only applies to stable backports. For kernels compiled with CONFIG_INIT_STACK_NONE=y, the value of __reserved bitfield in zen_patch_rev union on the stack may be garbage. If so, it will prevent correct microcode check when consulting p.ucode_rev, resulting in incorrect mitigation selection.

[PATCH] scsi: ufs: exynos: fix programming of HCI_UTRL_NEXUS_TYPE

by André Draszik

On Google gs101, the number of UTP transfer request slots (nutrs) is 32, and in this case the driver ends up programming the UTRL_NEXUS_TYPE incorrectly as 0. This is because the left hand side of the shift is 1, which is of type int, i.e. 31 bits wide. Shifting by more than that width results in undefined behaviour. Fix this by switching to the BIT() macro, which applies correct type casting as required. This ensures the correct value is written to UTRL_NEXUS_TYPE (0xffffffff on gs101), and it also fixes a UBSAN shift warning: UBSAN: shift-out-of-bounds in drivers/ufs/host/ufs-exynos.c:1113:21 shift exponent 32 is too large for 32-bit type 'int' For consistency, apply the same change to the nutmrs / UTMRL_NEXUS_TYPE write.
