It has been discussed here before, that the user and group IDs as well
as the auxiliary groups are a process property in POSIX and therefore a
process group property in Linux. There has been some disagreement on
how to implement this. As a first step I therefore created a patch
which virtualizes access to the IDs and group informatin in the task
struct. Andrew described the function names and from then on everything
was straight forward. The changes are numerous (98k patch) and all over
the place. But I think I caught most of the changes. Failures to do
this will show up right away since the task structure element has been
renamed.
The patch is at
