From: Emanuele Ghidoli <emanuele.ghidoli(a)toradex.com> On a few platforms such as TI's AM69 device, disable_irq() fails to keep track of the interrupts that happen between disable_irq() and enable_irq() and those interrupts are missed. Use the ->irq_unmask() and ->irq_mask() methods instead of ->irq_enable() and ->irq_disable() to correctly keep track of edges when disable_irq is called. This solves the issue of disable_irq() not working as expected on such platforms. Fixes: 23265442b02b ("ARM: davinci: irq_data conversion.")

[PATCH 0/2] pinctrl: intel: platform: fix error path in device_for_each_child_node()

This series fixes an error path where the reference of a child node is not decremented upon early return.

[PATCH] PM / devfreq: Fix atomicity violation in devfreq_update_interval()

by Qiu-ji Chen

The atomicity violation occurs when the variables cur_delay and new_delay are defined. Imagine a scenario where, while defining cur_delay and new_delay, the values stored in devfreq->profile->polling_ms and the delay variable change. After acquiring the mutex_lock and entering the critical section, due to possible concurrent modifications, cur_delay and new_delay may no longer represent the correct values. Subsequent usage, such as if (cur_delay > new_delay), could cause the program to run incorrectly, resulting in inconsistencies. To address this issue, it is recommended to acquire a lock in advance, ensuring that devfreq->profile->polling_ms and delay are protected by the lock when being read. This will help ensure the consistency of the program. This possible bug is found by an experimental static analysis tool developed by our team. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations.

[PATCH] Input: adp5588-keys - Added checking of key and key_val variables

by Denis Arefev

If the adp5588_read function returns 0, then there will be an overflow of the kpad->keycode buffer. If the adp5588_read function returns a negative value, then the logic is broken - the wrong value is used as an index of the kpad->keycode array.

[PATCH v3 1/3] Drivers: hv: vmbus: Disable Suspend-to-Idle for VMBus

by Erni Sri Satya Vennela

This change is specific to Hyper-V based VMs. If the Virtual Machine Connection window is focused, a Hyper-V VM user can unintentionally touch the keyboard/mouse when the VM is hibernating or resuming, and consequently the hibernation or resume operation can be aborted unexpectedly. Fix the issue by no longer registering the keyboard/mouse as wakeup devices (see the other two patches for the changes to drivers/input/serio/hyperv-keyboard.c and drivers/hid/hid-hyperv.c). The keyboard/mouse were registered as wakeup devices because the VM needs to be woken up from the Suspend-to-Idle state after a user runs "echo freeze > /sys/power/state". It seems like the Suspend-to-Idle feature has no real users in practice, so let's no longer support that by returning -EOPNOTSUPP if a user tries to use that. $echo freeze > /sys/power/state > bash: echo: write error: Operation not supported Fixes: 1a06d017fb3f ("Drivers: hv: vmbus: Fix Suspend-to-Idle for Generation-2 VM") Cc: stable(a)vger.kernel.org Signed-off-by: Saurabh Sengar <ssengar(a)linux.microsoft.com> Signed-off-by: Erni Sri Satya Vennela <ernis(a)linux.microsoft.com> --- Changes in v2: * Add "#define vmbus_freeze NULL" when CONFIG_PM_SLEEP is not enabled. * Change commit message to clarify that this change is specifc to Hyper-V based VMs. Changes in v3: * Add 'Cc: stable(a)vger.kernel.org' in sign-off area. --- drivers/hv/vmbus_drv.c | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-) diff --git a/drivers/hv/vmbus_drv.c b/drivers/hv/vmbus_drv.c index 965d2a4efb7e..8f445c849512 100644 --- a/drivers/hv/vmbus_drv.c +++ b/drivers/hv/vmbus_drv.c @@ -900,6 +900,19 @@ static void vmbus_shutdown(struct device *child_device) } #ifdef CONFIG_PM_SLEEP +/* + * vmbus_freeze - Suspend-to-Idle + */ +static int vmbus_freeze(struct device *child_device) +{ +/* + * Do not support Suspend-to-Idle ("echo freeze > /sys/power/state") as + * that would require registering the Hyper-V synthetic mouse/keyboard + * devices as wakeup devices, which can abort hibernation/resume unexpectedly. + */ + return -EOPNOTSUPP; +} + /* * vmbus_suspend - Suspend a vmbus device */ @@ -938,6 +951,7 @@ static int vmbus_resume(struct device *child_device) return drv->resume(dev); } #else +#define vmbus_freeze NULL #define vmbus_suspend NULL #define vmbus_resume NULL #endif /* CONFIG_PM_SLEEP */ @@ -969,7 +983,7 @@ static void vmbus_device_release(struct device *device) */ static const struct dev_pm_ops vmbus_pm = { - .suspend_noirq = NULL, + .suspend_noirq = vmbus_freeze, .resume_noirq = NULL, .freeze_noirq = vmbus_suspend, .thaw_noirq = vmbus_resume, -- 2.34.1

Fix the issue by no longer registering the keyboard/mouse as wakeup devices (see the other two patches for the changes to drivers/input/serio/hyperv-keyboard.c and drivers/hid/hid-hyperv.c). The keyboard/mouse were registered as wakeup devices because the VM needs to be woken up from the Suspend-to-Idle state after a user runs "echo freeze > /sys/power/state". It seems like the Suspend-to-Idle feature has no real users in practice, so let's no longer support that by returning -EOPNOTSUPP if a user tries to use that. $echo freeze > /sys/power/state > bash: echo: write error: Operation not supported Fixes: 1a06d017fb3f ("Drivers: hv: vmbus: Fix Suspend-to-Idle for Generation-2 VM") Signed-off-by: Saurabh Sengar <ssengar(a)linux.microsoft.com> Signed-off-by: Erni Sri Satya Vennela <ernis(a)linux.microsoft.com> --- Changes in v2: * Add "#define vmbus_freeze NULL" when CONFIG_PM_SLEEP is not enabled. * Change commit message to clarify that this change is specifc to Hyper-V based VMs. --- drivers/hv/vmbus_drv.c | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-) diff --git a/drivers/hv/vmbus_drv.c b/drivers/hv/vmbus_drv.c index 965d2a4efb7e..8f445c849512 100644 --- a/drivers/hv/vmbus_drv.c +++ b/drivers/hv/vmbus_drv.c @@ -900,6 +900,19 @@ static void vmbus_shutdown(struct device *child_device) } #ifdef CONFIG_PM_SLEEP +/* + * vmbus_freeze - Suspend-to-Idle + */ +static int vmbus_freeze(struct device *child_device) +{ +/* + * Do not support Suspend-to-Idle ("echo freeze > /sys/power/state") as + * that would require registering the Hyper-V synthetic mouse/keyboard + * devices as wakeup devices, which can abort hibernation/resume unexpectedly. + */ + return -EOPNOTSUPP; +} + /* * vmbus_suspend - Suspend a vmbus device */ @@ -938,6 +951,7 @@ static int vmbus_resume(struct device *child_device) return drv->resume(dev); } #else +#define vmbus_freeze NULL #define vmbus_suspend NULL #define vmbus_resume NULL #endif /* CONFIG_PM_SLEEP */ @@ -969,7 +983,7 @@ static void vmbus_device_release(struct device *device) */ static const struct dev_pm_ops vmbus_pm = { - .suspend_noirq = NULL, + .suspend_noirq = vmbus_freeze, .resume_noirq = NULL, .freeze_noirq = vmbus_suspend, .thaw_noirq = vmbus_resume, -- 2.34.1

[PATCH net] Revert "net: libwx: fix alloc msix vectors failed"

by Duanqiang Wen

This reverts commit 69197dfc64007b5292cc960581548f41ccd44828. commit 937d46ecc5f9 ("net: wangxun: add ethtool_ops for channel number") changed NIC misc irq from most significant bit to least significant bit, the former condition is not required to apply this patch, because we only need to set irq affinity for NIC queue irq vectors. this patch is required after commit 937d46ecc5f9 ("net: wangxun: add ethtool_ops for channel number") was applied, so this is only relevant to 6.6.y branch.
