Hi
Since linux currently doesn't support more than 32 groups per process, I created a patch which expands this limit (65536 at the moment, but this is quite abitrary).
It replaces the static groups array with a dynamically allocated array (which is reference counted, so that we don't need to copy it on forking).
The groups array is kept sorted (which is easy, because sys_setgroups always replaces the whole array), and is searched efficiently by using a binary search algorithmn.
Since I'm not very experienced in kernel hacking, I'd like to know if someone has done a similar patch (at least I could then compare my code with it).
If there is interest, I'll post my patch here - but I didn't want to fill your inboxes with something most people will find useless (2^16 groups is quite a lot ;-) ).
