attached is the first in a series of patches that is intended to
remove the current limitation on group membership.
this patch should remove the dependancy on the definition of
NGROUPS_MAX as a static constant and implement it as a writable
sysconf variable of the same. it should also make the necessary
changes to the codebase to support those.
i need some guidance as to what i should re-define NGROUPS_MAX to be
(so that code that depends on it can continue to operate, i'm thinking
just make it 16 but perhaps it would be worth extending the default
while we're at it to something like 64??). i also need feedback on
any braindamage in the current changes.
the next step will be to extend the kernel groups and map them back
to the user structs / calls. finally i'll extend the user groups
and implement those calls.
nb: not tested the code (it builds) ... was intending to test it on
my XEN box but only just realised that Xen on amd64 isn't working.
:-(
happy for any questions that may help guide the process.
What do you do about NFS?
I seem to remember that NFWS had a maximum number of groups supported..
