Actor and Partner details can be accessed via proc-fs, sys-fs
entries or netlink interface. These interfaces are world readable
at this moment. The earlier patch-series made the LACP communication
secure to avoid nuisance attack from within the same L2 domain but
it did not prevent "someone unprivileged" looking at that information
on host and perform the same act.
This patch essentially avoids spitting those entries if the user
in question does not have enough privileges.

With this patch, actor_oper_port_state and partner_oper.port_state are
not displayed in /proc, but that information is available via netlink
from bond_fill_slave_info().
I suspect you do not deem these two values as critical to the security
of the system, but wanted to confirm before ACKing.

Yes, one can very easily figure out that LACP is used in the system
with parameters like bond-mode, lacp-rate, or the port-state. I feel
these do not need to be hidden from unprivileged users to ensure
security. Principally hiding enough to ensure security would be good
rather than hiding everything. However if there is a scenario where
exposing these values is a threat (in the same sense) then it's not
lot of extra work to achieve that and I'm open to make those change.

Sounds fine to me. I just wanted to be sure the diffrence between the
information displayed in various modes was intentional (or at least not
unintentional) and did not conflict with your plans.
