This helper obtains the active namespace from current and returns pid, tgid,
device and namespace id as seen from that namespace, allowing to instrument
a process inside a container.
Device is read from /proc/self/ns/pid, as in the future it's possible that
different pid_ns files may belong to different devices, according
to the discussion between Eric Biederman and Yonghong in 2017 linux plumbers
conference.
Currently bpf_get_current_pid_tgid(), is used to do pid filtering in bcc's
scripts but this helper returns the pid as seen by the root namespace which is
fine when a bcc script is not executed inside a container.
When the process of interest is inside a container, pid filtering will not work
if bpf_get_current_pid_tgid() is used. This helper addresses this limitation
returning the pid as it's seen by the current namespace where the script is
executing.

This helper has the same use cases as bpf_get_current_pid_tgid() as it can be
used to do pid filtering even inside a container.

For example a bcc script using bpf_get_current_pid_tgid() (tools/funccount.py):

        u32 pid = bpf_get_current_pid_tgid() >> 32;
        if (pid != <pid_arg_passed_in>)
                return 0;
Could be modified to use bpf_get_current_pidns_info() as follows:

        struct bpf_pidns pidns;
        bpf_get_current_pidns_info(&pidns, sizeof(struct bpf_pidns));
        u32 pid = pidns.tgid;
        u32 nsid = pidns.nsid;
        if ((pid != <pid_arg_passed_in>) && (nsid != <nsid_arg_passed_in>))
                return 0;

To find out the name PID namespace id of a process, you could use this command:

$ ps -h -o pidns -p <pid_of_interest>

Or this other command:

$ ls -Li /proc/<pid_of_interest>/ns/pid

I prefer to break this into two patches to reduce
the potential merging conflicts:
   patch 1: fs/internal.h, fs/namei.c, include/linux/namei.h
   patch 2: rest of changes
patch 1 is simply a preparing patches to make filename_lookup
available later.

Copies => Copy.
Maybe something like below:
Get tgid, pid and namespace id as seen by the current namespace, and 
device major/minor numbers from device /proc/self/ns/pid. Such
information is stored in *pidns* of size *size*.

Let us remove ECHILD and ENOTDIR and replace it with ENOENT as I
described below.

Please *do verify* what happens when namespaces or pid_ns are not
configured.

Please add a comment for dev for how device major and minor number are 
derived. User space gets device major and minor number, they need to
compare to the corresponding major/minor numbers returned by this helper.

Please put an empty line. As a general rule for readability,
put an empty line if control flow is interrupted, e.g., by
"return", "break" or "continue". At least this is what
I saw most in bpf mailing list.

An empty line. Also, there is nothing to clear.
I prefer an error code -ENOENT.

You can set
	ret = -EINVAL;
here

Different functionality, an empty line.

Adding below to free kmem cache memory
	kmem_cache_free(names_cachep, fname);

In the above, we checked task_active_pid_ns().
If not returning NULL, we have a valid pid ns. So the above
filename_lookup should not go wrong. We can still keep
the error checking though.

To prevent we are running in arbitrary task (e.g., idle task)
context which may introduce sleeping issues, the following
probably appropriate:

        if (in_nmi() || in_softirq())
                return -EPERM;

Anyway, if in nmi or softirq, the namespace and pid/tgid
we get may be just accidentally associated with the bpf running
context, but it could be in a different context. So such info
is not reliable any way.

Could you use new map definitions. Search
"SEC(".maps")" for examples.

I would like you to compare device major/minor, namespace id,
pid and tid. We should test everything here.

Please use libbpf perf APIs.

It would be good if the test actually create a namespace and do the test.

Do you think it is possible to use the existing test_progs 
infrastructure. The current one without creating pid namespace
surely fit in. Not sure if we add creating/deleting namespace,
I would think it should fit in as well.

A better condition is (from helper bpf_probe_write_user()):
