[PATCH 1/7] net: macb: manage the netdev lifetime with devres

[Jiale Yao]

macb_remove() frees the netdev while its managed IRQs are only
released after the remove callback returns. An interrupt in that window
can dereference the freed netdev or queue data.

Allocate the netdev with devres as well. Since the IRQs are registered
later, devres releases them before freeing the netdev and closes the
lifetime gap.

[PATCH 3/7] net: hip04: manage the netdev lifetime with devres

[Jiale Yao]

hip04_remove() frees the netdev before the managed IRQ is released
after the remove callback. Since the IRQ handler receives the netdev as
its data pointer, a late interrupt can access freed memory.

Use a managed netdev allocation. Devres then releases the IRQ, which is
registered later, before releasing the netdev.

hisi_femac_drv_remove() frees the netdev while the shared managed IRQ

[PATCH 6/7] net: ravb: fix resource teardown ordering

[Jiale Yao]

ravb_remove() frees the netdev before devres releases the managed IRQs.
The handlers use the netdev as their data pointer, so an interrupt during
that window can access freed memory. Probe error paths have the same
ordering problem.

The remove callback also returns when runtime resume fails. That leaves
the netdev registered while the driver core still releases its managed
resources. A running interface already holds a runtime PM reference, so
the extra get cannot invoke a failing resume. A resume failure therefore
occurs while the interface is down and ndo_stop() will not be called.

Place the IRQ resources in a dedicated devres group and release it before
freeing the netdev. Continue unregistering and freeing software resources
when runtime resume fails, but skip the unmatched runtime PM put.

[PATCH 7/7] net: sxgbe: manage IRQ data lifetimes with devres

[Jiale Yao]

sxgbe_drv_remove() frees the netdev and hardware operations while
managed IRQs remain registered until the remove callback returns. The
handlers dereference these objects, so an interrupt in that window can
access freed memory.

Allocate both objects with devres. They are acquired before the IRQs and
are consequently released only after the IRQ resources have been
removed.
