RFC: Is SM_SIMU_CRASH (in rpc.statd) needed?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Does anybody know who uses SM_SIMU_CRASH and is it
still needed? I'm getting some push back from our
security folks to plug this DoS hole up...

How is it a DoS? statd ignores any SM_SIMU_CRASH from a non-loopback address that does not use a privileged port. To invoke it, you basically have to be a privileged local user.

Right now, no one uses it, but I think we should reserve the right to use it in the future. This could be part of a more robust interface between lockd and statd.
