This keeps the flag but makes it hidden so that existing clients do not
encounter an error if we were to have removed the flag.

nsenter: simplify netlink parsing
This just moves everything to one function so we don't have to pass a
bunch of things to functions when there's no real benefit. It also makes
the API nicer.

Carl Henrik Lunde 0a45903563 Support 32 bit UID on i386
The original SETUID takes a 16 bit UID.  Linux 2.4 introduced  a new
syscall, SETUID32, with support for 32 bit UIDs.  The setgid wrapper
already uses SETGID32.

Zhao Lei bb067f55aa Test: Make TestCaptureTestFunc pass in localunittest
TestCaptureTestFunc failed in localunittest:
 # make localunittest
 === RUN   TestCaptureTestFunc
 --- FAIL: TestCaptureTestFunc (0.00s)
         capture_test.go:26: expected package "github.com/opencontainers/runc/libcontainer/stacktrace" but received "_/root/runc/libcontainer/stacktrace"
 #

Reason: the path for stacktrace is a fixed string which
only valid for container environment.
And we can switch to relative path to make both in-container
and out-of-container test works.

After patch:
 # make localunittest
 === RUN   TestCaptureTestFunc
 --- PASS: TestCaptureTestFunc (0.00s)

nsenter: major cleanup
Removed a lot of clutter, improved the style of the code, removed
unnecessary complexity. In addition, made errors unique by making bail()
exit with a unique error code. Most of this code comes from the current
state of the rootless containers branch.

Justin Cormack 834e53144b Do not create /dev/fuse by default
This device is not required by the OCI spec.

The rationale for this was linked to https://github.com/docker/docker/issues/2393

So a non functional /dev/fuse was created, and actual fuse use still is
required to add the device explicitly. However even old versions of the JVM
on Ubuntu 12.04 no longer require the fuse package, and this is all not
needed.

Davanum Srinivas 27915db384 Adding /proc/timer_list to the masked paths list
/proc/timer_list seems to leak information about the host. Here is
an example from a busybox container running on docker+kubernetes.

tests: add requires cgroups_kmem
On older kernels or kernels were CONFIG_MEMCG_KMEM is not set some cgroup tests
cannot be run. We simply test for the existence of the file
"${CGROUP_BASE_PATH}/memory/memory.kmem.limit_in_bytes" which should be
sufficient to conclude that CONFIG_MEMCG_KMEM is not set.

Alexander Morozov 7679c80be5 libcontainer/configs: make hooks run safer
It's possible that `cmd.Process` is still nil when we reach timeout.
Start creates `Process` field synchronously, and there is no way to such
race.
