2021-11-18net: ethernet: dec: tulip: de4x5: fix possible array overflows in ↵Teng Qi
type3_infoblock() The definition of macro MOTO_SROM_BUG is: #define MOTO_SROM_BUG (lp->active == 8 && (get_unaligned_le32( dev->dev_addr) & 0x00ffffff) == 0x3e0008) and the if statement if (MOTO_SROM_BUG) lp->active = 0; using this macro indicates lp->active could be 8. If lp->active is 8 and the second comparison of this macro is false. lp->active will remain 8 in: lp->phy[lp->active].gep = (*p ? p : NULL); p += (2 * (*p) + 1); lp->phy[lp->active].rst = (*p ? p : NULL); p += (2 * (*p) + 1); lp->phy[lp->active].mc = get_unaligned_le16(p); p += 2; lp->phy[lp->active].ana = get_unaligned_le16(p); p += 2; lp->phy[lp->active].fdx = get_unaligned_le16(p); p += 2; lp->phy[lp->active].ttm = get_unaligned_le16(p); p += 2; lp->phy[lp->active].mci = *p; However, the length of array lp->phy is 8, so array overflows can occur. To fix these possible array overflows, we first check lp->active and then return -EINVAL if it is greater or equal to ARRAY_SIZE(lp->phy) (i.e. 8).

Michal adds tracking for when a VSI is being released to prevent null pointer dereference when managing filters.

As reported in [1], e100 was no longer working for suspend/resume cycles. The previous commit mentioned in the fixes appears to have broken things and this attempts to practice best known methods for device power management and keep wake-up working while allowing suspend/resume to work. To do this, I reorder a little bit of code and fix the resume path to make sure the device is enabled.

hns_dsaf_ge_srst_by_port() The if statement: if (port >= DSAF_GE_NUM) return; limits the value of port less than DSAF_GE_NUM (i.e., 8).

2021-11-18ata: libahci: Adjust behavior when StorageD3Enable _DSD is setMario Limonciello
The StorageD3Enable _DSD is used for the vendor to indicate that the disk should be opted into or out of a different behavior based upon the platform design. For AMD's Renoir and Green Sardine platforms it's important that any attached SATA storage has transitioned into DevSlp when s2idle is used. If the disk is left in active/partial/slumber, then the system is not able to resume properly. When the StorageD3Enable _DSD is detected, check the system is using s2idle and DevSlp is enabled and if so explicitly wait long enough for the disk to enter DevSlp.

2021-11-17iio: trigger: Fix reference countingLars-Peter Clausen
In viio_trigger_alloc() device_initialize() is used to set the initial reference count of the trigger to 1. Then another get_device() is called on trigger. This sets the reference count to 2 before the trigger is returned. iio_trigger_free(), which is the matching API to viio_trigger_alloc(), calls put_device() which decreases the reference count by 1. But the second reference count acquired in viio_trigger_alloc() is never dropped. As a result the iio_trigger_release() function is never called and the memory associated with the trigger is never freed. Since there is no reason for the trigger to start its lifetime with two reference counts just remove the extra get_device() in viio_trigger_alloc(). Fixes: 5f9c035cae18 ("staging:iio:triggers.

2021-11-17iio: adc: stm32: fix a current leak by resetting pcsel before disabling vddaFabrice Gasnier
Some I/Os are connected to ADC input channels, when the corresponding bit in PCSEL register are set on STM32H7 and STM32MP15. This is done in the prepare routine of stm32-adc driver. There are constraints here, as PCSEL shouldn't be set when VDDA supply is disabled. Enabling/disabling of VDDA supply in done via stm32-adc-core runtime PM routines (before/after ADC is enabled/disabled). Currently, PCSEL remains set when disabling ADC. Later on, PM runtime can disable the VDDA supply. This creates some conditions on I/Os that can start to leak current. So PCSEL needs to be cleared when disabling the ADC.
