68b41854b2 Merge "Install ndisc6 package in element script" 2019-12-03 22:41:09 +00:00
Harald Jensås
7948fee7e2 Install ndisc6 package in element script
The ndisc6 package is not yet available in EPEL 8.
See: https://bugzilla.redhat.com/show_bug.cgi?id=1779134

Until the package is available set the pkg-map to "" for
the ndisc6 package when distro is redhat and install the
package using || true in the element script instead so
that CentOS 8 build's do not fail because of the missing
package.

Once the package is in EPEL 8 this change can be reverted.

b91e212434 Break retry loop on success in dhcp-all-interfaces
If rdisc6 is available, a node using this element will loops until
DIB_DHCP_TIMEOUT is reached because of a missing 'break' when rdisc6
return code is 0.
This will mark the dhcp-interface@.service unit as failed (because it
has the same timeout) and not bring any network interface online.

f94508d537 Add IPv6 support in dhcp-all-interfaces
When the rdisc6 utility is available probe for router
advertisement. configure eni and rhel-netscripts interfaces
to do IPv6 address configuration according to the flags
in the RA recived from the router.

The systemd service file timeout is DIB_DHCP_TIMEOUT * 2,
so that DHCPv4 can timout, and dhcpv6 run before the service
times out.

Retries are commented in dhclient.conf, without it we end up
trying DIB_DHCP_TIMEOUT * 60 before the client move on to
IPv6.

WHEN:
  Stateful address conf.    :          No
  Stateful other conf.      :          No
THEN:
  Do not run dhclient at all, autoconfiguration via
  SLAAC only.

WHEN:
  Stateful address conf.    :          No
  Stateful other conf.      :          Yes
THEN:
  Run "dhclient -6 -S", The ``-S`` option makes the
  dhcp client not request an address, only other
  options such as DNS servers and NTP servers from
  DHCPv6 server.

WHEN:
  Stateful address conf.    :          Yes
  Stateful other conf.      :          Yes
THEN:
  The dhcp client should request an address _and_ other
  options such as DNS servers and NTP servers from
  DHCPv6 server.

NOTE: No IPv6 support added for suse-netscripts

7e4e6cfff4 Add expected semicolons for dhclient.conf
This patch adds an expected semicolon to an end of statement in
dhclient.conf for dhcp-all-interfaces element. Without this fix, an
error occurs when an image is booted with a message,
'semicolon expected.'.

11d91501d0 Fix /etc/network/interfaces file contents
According to http://bit.ly/2HA4oDO and
the official Ubuntu manual
http://manpages.ubuntu.com/manpages/xenial/man5/interfaces.5.html
source-dir support has been removed from Ubuntu >= 16.04/Xenial

Once an image is generated and booted, moving the dhcp interface(s)
declaration(s) from /etc/network/interfaces into specific subentries
of /etc/network/interfaces.d and calling 'service networking restart'
just make your instance unreachable and all interfaces are left
unconfigured.

This patchset fixes this issue

97399e9bb1 Set the dhclient timeout to match DIB_DHCP_TIMEOUT
On initial boot when networking is brought up by cloud-init this
is the timeout that dhclient adheres to. Centos configures
"timeout 300" (for an EC2 bug) in their cloud image, which results
in a 5 minutes delay to boot in cases where no dhcp available (e.g. IPv6
SLAAC). To reduce this boot delay and to provide consistency with
places where we have set other dhcp timeouts set this to DIB_DHCP_TIMEOUT.

f249cec9f3 Checking link status according to DIB_DHCP_TIMEOUT
In slow networks like Infiniband it takes much time for the
interface to get the carrier. This patch enables this service
to run more then 20 seconds and limited by DIB_DHCP_TIMEOUT.

6d64a2aee6 Fix cylical systemd config for dhcp-all-interfaces
In Ubuntu/Debian, the default dependencies cannot be relied
upon as we enter into a cyclical dependency relationship which
prevents the unit from starting.

Added the required configuration to the systemd unit file.

This issue has also been observed in glean[0], which has a nearly
identical unit file for interface start-up.

97c01e48ed Move elements & lib relative to diskimage_builder package
Currently we have all our elements and library files in a top-level
directory and install them into
<root>/share/diskimage-builder/[elements|lib] (where root is either /
or the root of a virtualenv).

The problem with this is that editable/development installs (pip -e)
do *not* install data_files.  Thus we have no canonical location to
look for elements -- leading to the various odd things we do such as a
whole bunch of guessing at the top of disk-image-create and having a
special test-loader in tests/test_elements.py so we can run python
unit tests on those elements that have it.

data_files is really the wrong thing to use for what are essentially
assets of the program.  data_files install works well for things like
config-files, init.d files or dropping documentation files.

By moving the elements under the diskimage_builder package, we always
know where they are relative to where we import from.  In fact,
pkg_resources has an api for this which we wrap in the new
diskimage_builder/paths.py helper [1].

We use this helper to find the correct path in the couple of places we
need to find the base-elements dir, and for the paths to import the
library shell functions.

Elements such as svc-map and pkg-map include python unit-tests, which
we do not need tests/test_elements.py to special-case load any more.
They just get found automatically by the normal subunit loader.

I have a follow-on change (I69ca3d26fede0506a6353c077c69f735c8d84d28)
to move disk-image-create to a regular python entry-point.

Unfortunately, this has to move to work with setuptools.  You'd think
a symlink under diskimage_builder/[elements|lib] would work, but it
doesn't.

[1] this API handles stuff like getting files out of .zip archive
modules, which we don't do.  Essentially for us it's returning
__file__.
