What kind of hooks ?

I've been idling around the LSM hooks for quite a while and
I never had the need to add any... So, I'm quite puzzled to
know what kind of hooks do you need. :)

Sorry, but I don't see your point here...

You want to be able to restrict the access to a network card on the
basis of the MAC address ?

But, why don't you consider using the socket_create (and more generally,
the socket_* family) in place of adding new hooks ?

The point of a hook is to insert check-points to prevent people to
access features/data on the system. I hardly see the mac layer as a
feature/data by itself as it is part of "can I access network or not ?".

I might as well have missed your point, respected Sir (may I call you
respected Sir ?). :)

adding new lsm hooks

[umesh chandak]

hi ,

In wireless network ,most of the attacks occurs at mac
layer .so i think ,we should detect this attack at mac
layer itself.so I think we can add lsm hooks at mac
layer
in linux for wireless networks.so i want to add new
hooks in it  . therefore i want to know the procedure
of adding new hooks,which file should i change,which
functions should i write and like that .Hooks may be
of any type for time being .
                help me out.
                                        bye
