9 years agonspawn: fallback on bind mount when mknod fails

nspawn: fallback on bind mount when mknod fails

Some systems abusively restrict mknod, even when the device node already
exists in /dev. This is unfortunate because it prevents systemd-nspawn
from creating the basic devices in /dev in the container.

This patch implements a workaround: when mknod fails, fallback on bind
mounts.

Additionally, /dev/console was created with a mknod with the same
major/minor as /dev/null before bind mounting a pts on it. This patch
removes the mknod and creates an empty regular file instead.

In order to test this patch, I used the following configuration, which I
think should replicate the system with the abusive restriction on mknod:

  # grep devices /proc/self/cgroup
  4:devices:/user.slice/restrict
  # cat /sys/fs/cgroup/devices/user.slice/restrict/devices.list
  c 1:9 r
  c 5:2 rw
  c 136:* rw
  # systemd-nspawn --register=false -D .

v2:
 - remove "bind", it is not needed since there is already MS_BIND
v3:
 - fix error management when calling touch()
 - fix lowercase in error message

ARM: detect-virt: detect QEMU/KVM

QEMU/KVM guests do not have hypervisor nodes, but they do have
fw-cfg nodes (since qemu v2.3.0-rc0). fw-cfg nodes are documented,
see kernel doc Documentation/devicetree/bindings/arm/fw-cfg.txt,
and therefore we should be able to rely on it in this detection.

Unfortunately, we currently don't have enough information in the
DT, or elsewhere, to determine if we're using KVM acceleration
with QEMU or not, so we can only report 'qemu' at this time, even
if KVM is in use. This shouldn't really matter in practice though,
because if detect-virt is used interactively it will be clear to
the user whether or not KVM acceleration is present by the overall
speed of the guest. If used by a script, then the script's behavior
should not change whether it's 'qemu' or 'kvm'. QEMU emulated
guests and QEMU/KVM guests of the same type should behave
identically, only the speed at which they run should differ.

systemd-bootchart: Prevent closing random file descriptors

If the kernel has no CONFIG_SCHED_DEBUG option set, systemd-bootchart produces

many places where file descriptors are closed on failure (missing SCHED_DEBUG

 - following iterations in the loop see that the descriptor is non zero and do
   not open the corresponding file again;
 - "some cleanup" code closes already closed files and the descriptors are reused
   already, in particular for resulting .svg file;
