Re: [PATCH net 0/3] net: ethernet: disable async work before teardown

[BeaCox]

Hi,

The issues were found by manual code inspection while auditing
Ethernet remove paths for async work that can outlive the netdev (the
same teardown pattern as a missing cancel/disable_work_sync before
free_netdev). They were not hit in production and are not from syzbot.

Testing is as described in the cover letter: KASAN on QEMU/KVM
(x86-64, 2 vCPUs). There is no physical atl1 / enc28j60 / xgmac
hardware in the test setup; platform/SPI teardown was exercised with
test devices, and the atl1 probe path was not exercised.

If a later revision is needed for other reasons I will fold this into
the commit messages.

Thanks,
BeaCox
