[PATCH v5 net 0/7] i40e: re-init and UAF fixes

[Maciej Fijalkowski <maciej.fijalkowski@intel.com>]

v5:
- include three new patches to address last Sashiko review
  *
- do not release the irq lump in rebuild path in patch 7
- clear dangling pointers from rx and xdp rings arrays
v4:
- add preceding patch that fixes a case when some of re-init allocations
  failed and we missed de-registering netdev at failure path
- pull out i40e_vsi_setup() changes onto separate patch
v3:
- address UAF when ring arrays were freed before q_vector's ring
  containers (Sashiko, Jacob)
- remove bool params from alloc/free array routines (Simon)
v2:
- NULL vsi->tx_rings in i40e_vsi_alloc_arrays() (Sashiko)


Maciej Fijalkowski (7):
  i40e: unregister netdev before clearing VSI on reinit failure
  i40e: avoid null ptr dereference in i40e_ptp_stop()
  i40e: make ring pointers unreachable before freeing via rcu
  i40e: avoid deadlock when calling unregister_netdev()
  i40e: fix potential UAF in i40e_vsi_setup()'s error path
  i40e: do not expose netdev too early
  i40e: keep q_vectors array in sync with channel count changes
