It is not too difficult to fix up the conflicts. But this is a fairly
big change, so I think this bug should now be 'wontfix' for wheezy.
Sorry we didn't get it fixed earlier.
Sorry to hear that. Would a patch that simply increases the static
number of entries in the names array be an acceptable workaround? It
would decrease the change of hitting this bug.
Perhaps; do you have any idea what the limit should be?
Not really. I'm currently building a test kernel with the limit set to
25 (instead of 20). I'll see if I can boot that kernel one of these days
to see if 25 is enough.
The 25 might be enough for my situation, but other users could of course
need an even bigger number...
We do need to consider that this costs 76 bytes per name per task for
which auditing is enabled, and there are normally hundreds or thousands
of tasks running, so extra names aren't cheap.
What would you consider the upper limit to which we could increase the
number? Just so I know at which limit I can stop building test kernels.

Rik
