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.

This is extremely useful for faking it as "i386" on x86_64 systems, for
instance.

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

For the specific case that is clearly the better solution,
as it already exists, and it handles the weird 32/64bit
logic. The ELF_PLATFORM bit I was commenting on was 32bit
only.

I'm not ready to implement any new functionality at the moment,
but what I heard suggested and was it may be reasonable to allow
machine to be modified on a per uts namespace basis. If that
kind of thing is ever to happen ELF_PLATFORM needs to be per
uts on x86. Actually allowing modification of machine is
an entirely different conversation.

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.

I've added a deprecation entry for the kernel_thread export and plan
to convert all users to the kthread API. Any help on that is of course
greatly appreciated.

Odd. I haven't been getting bounces, and I'm not subscribed.

I wonder if some of the principals in the conversation were given an
explicit exception. If so that is a subtle pain.

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)

Quoting Serge E. Hallyn (serue@us.ibm.com):
> Here is a new version of the init_utsname patch. I'm sending a

> patch.

Then again, I can't find the rest of the /7 series. I'm assuming at
least those cc:d got the full set, so will the resend.

Here is the updated the utsname() usage patch.

From: Serge Hallyn <serue@us.ibm.com>
Subject: [PATCH 2/7] uts namespaces: switch to using uts namespaces

Replace references to system_utsname to the per-process uts namespace
where appropriate. This includes things like uname.

Changes: Per Eric Biederman's comments, use the per-process uts namespace
for ELF_PLATFORM, sunrpc, and parts of net/ipv4/ipconfig.c

Signed-off-by: Serge E. Hallyn <serue@us.ibm.com>
