Subject: [Intel-wired-lan] [PATCH net v1 0/2] Fix close path on shutdown and remove in iavf driver.
Date: Wed,  6 Jul 2022 15:54:35 +0200	[thread overview]
Message-ID: <20220706135437.1695672-1-mateusz.palczewski@intel.com> (raw)

iavf_shutdown was implementing an incomplete version
of iavf_remove. It misses several calls to the kernel like
iavf_free_misc_irq, iavf_reset_interrupt_capability, iounmap
that might break the system on reboot or hibernation.

Fix a deadlock introduced by commit
974578017fc1f ("iavf: Add waiting so the port is initialized in remove")
due to race condition between iavf_shutdown and iavf_remove, where
iavf_remove stucks forever in while loop since iavf_shutdown already
set __IAVF_REMOVE adapter state.

  iavf: Fix shutdown pci callback to match the remove one
  iavf: Fix race condition between iavf_shutdown and iavf_remove
