Will we be able to have a single application be in multiple name-spaces?
A single application certainly. But then an application can be composed
of multiple processes which can be composed of multiple threads.
In my current patches a single task_struct belongs to a single network
namespace. That namespace is used when creating sockets. The sockets
themselves have a namespace tag and that is used when transmitting
packets, or otherwise operating on the socket.
So if you pass a socket from one process to another you can have
sockets that belong to different network namespaces in a single task.
Any chance it could allow one to use a single threaded, single process
and do something like
int fd1 = socket(...., namespace1);
int fd2 = socket(...., namespace2);
Or, maybe a sockopt or similar call to move a socket into a particular
namespace?
I can certainly see it being useful to allow a default name-space per
process, but it would be nice
to also allow explicit assignment of a socket to a name-space for
applications that want to span
a large number of name-spaces.
Thanks,
Ben
