In some places, particularly drivers and __init code, the init utsns is the
appropriate one to use. This patch replaces those with a the init_utsname
helper.

I think this one needs to be utsname()->machine.
Currently it doesn't matter. But Herbert has expressed
the desire to make a machine appear like an older one.

This also probably makes sense as utsname(). It doesn't
really matter as this is before init is executed. But logically
this is a user space or per namespace action.

Using nodename is practically the definition of something
that should per namespace I think. Plus it would be really inconsistent
to use utsname() and the init_utsname for the nfs rpc calls.
Unless I am missing something.

Right, I was kind of favoring using init_utsname() for anything
__init. But utsname() will of course work just as well there.

It seemed like this would be happening in any old context, so that
current->uts_ns could be any process'. Tracing it back further,
it seems like nfs+lockd should have the context available. So I'll
switch this as well.

Could 'setarch' be of any help here? Works fine for us. Or am I missing
something?

Basically anything that should move to klibc I favor using
utsname() for. That tends to make it clear it follows
the usual user space rules.
With a little luck HPA might actually have this code deleted
in -mm before we get to far.

I have not traced that path recently. So I don't remember.
This is one of those odd cases that makes a real difference.
This reminds me of another piece of the conversation.
kernel_thread vs. kthread, and the oddities of daemonize.
In general user space cannot kill kernel threads, so having
a kernel thread inside a namespace is dangerous because it
means the namespace can never exit.
There are two ways to avoid the associated problems.
- modify daemonize to always use the instance of that
namespace associated with init_task.
- modify all interesting kernel threads to use the
kthread api instead of kernel_thread. Using kthread
makes the kernel threads children of keventd and always
in the initial namespace instance. As such we know
we aren't inside of any user space namespace instance.

Here is a new version of the init_utsname patch. I'm sending a
new version of the utsname() patch in reply to the original [2/7]
patch.
From: Serge Hallyn <serue@us.ibm.com>
Subject: [PATCH 3/7] uts namespaces: use init_utsname when appropriate
In some places, particularly drivers and __init code, the init utsns is the
appropriate one to use. This patch replaces those with a the init_utsname
helper.
Changes: Removed several uses of init_utsname(). Hope I picked all the
right ones in net/ipv4/ipconfig.c. These are now changed to
utsname() (the per-process namespace utsname) in the previous
patch (2/7)
Signed-off-by: Serge E. Hallyn <serue@us.ibm.com>
