In the Linux kernel, the following vulnerability has been resolved:
net: fec: remove .ndo_poll_controller to avoid deadlocks
There is a deadlock issue found in sungem driver, please refer to the
commit ac0a230f719b (“eth: sungem: remove .ndo_poll_controller to avoid
deadlocks”). The root cause of the issue is that netpoll is in atomic
context and disable_irq() is called by .ndo_poll_controller interface
of sungem driver, however, disable_irq() might sleep. After analyzing
the implementation of fec_poll_controller(), the fec driver should have
the same issue. Due to the fec driver uses NAPI for TX completions, the
.ndo_poll_controller is unnecessary to be implemented in the fec driver,
so fec_poll_controller() can be safely removed.
