    smc: switch to usage of IB_PD_UNSAFE_GLOBAL_RKEY · 263eec9b
    Ursula Braun authored
    Currently, SMC enables remote access to physical memory when a user
    has successfully configured and established an SMC-connection until ten
    minutes after the last SMC connection is closed. Because this is considered
    a security risk, drivers are supposed to use IB_PD_UNSAFE_GLOBAL_RKEY in
    such a case.
    
    This patch changes the current SMC code to use IB_PD_UNSAFE_GLOBAL_RKEY.
    This improves user awareness, but does not remove the security risk itself.
