Merge patch series "Fix device removal order for Apple dart iommu"
Janne Grunau <j@jannau.net> says:
Starting with v2024.10 dev_iommu_dma_unmap calls during device removal
trigger a NULL pointer dereference in the Apple dart iommu driver. The
iommu device is removed before its user. The sparsely used DM_FLAG_VITAL
flag is intended to describe this dependency. Add it to the driver.
Adding this flag is unfortunately not enough since the boot routines
except the arm one simply remove all drivers. Add and use a new function
which calls
dm_remove_devioce_flags(DM_REMOVE_ACTIVE_ALL | DM_REMOVE_NON_VITAL);
dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);
to ensure this order dependency is head consistently.
Janne Grunau [Sat, 23 Nov 2024 21:44:05 +0000 (22:44 +0100)]
dm: Add dm_remove_devices_active() for ordered device removal
This replaces dm_remove_devices_flags() calls in all boot
implementations to ensure non vital devices are consistently removed
first. All boot implementation except arch/arm/lib/bootm.c currently
just call dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL). This can result
in crashes when dependencies between devices exists. The driver model's
design document describes DM_FLAG_VITAL as "indicates that the device is
'vital' to the operation of other devices". Device removal at boot
should follow this.
Instead of adding dm_remove_devices_flags() with (DM_REMOVE_ACTIVE_ALL |
DM_REMOVE_NON_VITAL) everywhere add dm_remove_devices_active() which
does this.
Fixes a NULL pointer deref in the apple dart IOMMU driver during EFI
boot. The xhci-pci (driver which depends on the IOMMU to work) removes
its mapping on removal. This explodes when the IOMMU device was removed
first.
dm_remove_devices_flags() is kept since it is used for testing of
device_remove() calls in dm.

Skipping SPI calibration doesn't bring harm since there's no need
for the flash golden values stored during SPI calibration.
Instead, they are now read during the spi_nor_read_id call in the

alignment of 1 byte is used. Thus, the buffer doesn't work for performing
DMA, and garbage data is read.
While looking at this issue, I also noticed that if no alignment specified

default is no alignment. Therefore, other users of fs_read_alloc() which
specify align=0 may be broken as well.

Historically other filesystems such as ext4 or fat have not been

as printf.

still within its working temperature range.
