[PATCH net-next 0/4] rocker: transaction fixes

[Simon Horman <simon.horman@netronome.com>]

Hi,

this series addresses what appear to be errors in the handling of
prepare and then commit transactions in the rocker driver.

In all cases the problem is that data structures visible outside of
the transaction are modified during the prepare phase.

In the case of the first two patches this results in the kernel reporting a
BUG. I have noted test-cases in the change logs.

The remaining two patches do not fix bugs that manifest as far as
I can tell. Rather, they are correctness fixes.

Simon Horman (4):
  rocker: do not delete fdb entries in rocker_port_fdb_flush() when
    preparing transactions
  rocker: do not modify fdb table in rocker_port_fdb() when preparing
    transactions
  rocker: do not make neighbour entry changes when preparing
    transactions
  rocker: make rocker_port_internal_vlan_id_{get,put}()
    non-transactional
