    pfkey: fix SA and SP flush sequence · 8be987d7
    Jamal Hadi Salim authored
    RFC 2367 says flushing behavior should be:
    1) user space -> kernel: flush
    2) kernel: flush
    3) kernel -> user space: flush event to ALL listeners
    
    This is not realistic today in the presence of selinux policies
    which may reject the flush etc. So we make the sequence become:
    1) user space -> kernel: flush
    2) kernel: flush
    3) kernel -> user space: flush response to originater from #1
    4) if there were no errors then:
    kernel -> user space: flush event to ALL listeners
