mtu crash
Raw
gistfile1.txt
possible timeline:
- gets dhcp lease, calls dhcp_lease_acquired
- sets mtu to 9000 (asynchronously, does not fail when the iface is up, may either claim to succeed or fail with the link down)
- calls dhcp4_update_address which then calls address_configure with dhcp4_address_handler
- address_configure builds a rtnl message to configure the link with the dhcp4_address_handler as the callback
- sends that message async
- link goes down, event generated
- link lease cleaned up
- link comes back up
- rtnl sends reply, triggers dhcp4_address_handler which calls link_set_dhcp_routes
- link->lease is bad, causes crash
