Revision bd91b56cb3b27492963caeb5fccefe20a986ca8d authored by Thomas Tai on 26 July 2018, 17:13:04 UTC, committed by Bjorn Helgaas on 26 July 2018, 17:13:04 UTC
When an fatal error is received by a non-bridge device, the device is
removed, and pci_stop_and_remove_bus_device() deallocates the device
structure. The freed device structure is used by subsequent code to send
uevents and print messages.
Hold a reference on the device until we're finished using it. This is not
an ideal fix because pcie_do_fatal_recovery() should not use the device at
all after removing it, but that's too big a project for right now.

# This example script retrieves the DHCP state of a given interface.
# In the interest of keeping the KVP daemon code free of distro specific
# information; the kvp daemon code invokes this external script to gather
# DHCP setting for the specific interface.
#
# Input: Name of the interface
#
# Output: The script prints the string "Enabled" to stdout to indicate
# that DHCP is enabled on the interface. If DHCP is not enabled,
# the script prints the string "Disabled" to stdout.
#
# Each Distro is expected to implement this script in a distro specific
# fashion. For instance on Distros that ship with Network Manager enabled,
# this script can be based on the Network Manager APIs for retrieving DHCP
# information.
