ifupdown2: Disable IPv6 duplicate address detection on VRR interfaces
Ticket: CM-11511
Reviewed By: CCR-4890
Testing Done: Used "address-virtual" keyword to create VRR interface with IPv6
address. Checked sysctl and dad failures.
In a VRR setup, both switches are programmed with the same IPv6 address and that
address is active on both switches. This causes the IPv6 duplicate address
detection to kick in and diable the use of one of the address on one of the
switches. This patch causes duplicate address detection to be disabled on VRR
interfaces by setting the net.ipv6.conf.<ifname>.accept_dad and
net.ipv6.conf.<ifname>.dad_transmits sysctl's to 0. The only IPv6 addresses
which are defined on these interfaces are the virtual addresses and the link
local address (which is unused). No other operational IPv6 addresses should ever
be assigned to these interfaces. Instead, operational IPv6 addresses should be
assigned to the "base", or lower, interface of the VRR interface.

ifreload always deletes and adds back a host IP address
if that address is specified without a "/" and without a "netmask" config.
The problem is fixed so that _inet_address_convert_to_cidr() handles a missing
"/" and a missing "netmask" config. The host addresses is no longer added to a
list of addresses we will del/add. The patch was simply to add a case for the
missing "/" and a missing "netmask".
ifupdown2.TestMakoJson test was failing because the json values werent trimmed
Because of a trailing whitespace, a list of iface had an empty value, ifupdown2
was throwing an exception.
If called with close_fds=True the subprocess module will try to close every fd
from 3 to MAXFD before executing the specified command. This is done in Python
not even with a C-implementation which truly affecting performances.
This patch aims to better handle the file descriptor used by ifupdown2. Either
by closing them after use or by setting the close-on-exec flag for the file
descriptor, which causes the file descriptor to be automatically
(and atomically) closed when any of the exec-family functions succeed.
With the actual patch all tests are passing, I can't think of any future issue
but if any a possible future modification might be to use the parameter
'preexec_fn', which allows us to set function which will be executed in the
child process before executing the command line. We can always manually close
any remaining open file descriptors with something like:
>>> os.listdir('/proc/self/fd/')
['0', '1', '2', ‘3’, etc..]
>>> for fd in os.listdir('/proc/self/fd/')
>>> if int(fd) > 2:
>>> os.close(fd)
This patch is also totally re-organising the use of subprocesses. By removing
all subprocess code redundancy.

- This patch makes sure a slave brings up a vrf master only

is brought up, skip master bring up and throw an error.
- Since the addon modules also need to use the ALL and WITH_DEPENDS

In which case we end up not configuring the static address because we
