This commit fixes a change in behaviour introduced by "460906d0552d" ("skip adding

Fix mstp settings ordering issues when bridge stp is toggled on and off
(when mstp settings are specified under the port)
Ticket: CM-6626
Reviewed By: CCR-3599
Testing Done: Tested the problem case mentioned in the bug (Plan to
re-work the fix a bit for 2.5.5)
problem:
mstp parameters can be specified under the port or under the bridge
When they are specified under the bridge, there should be no problem
(When you process the bridge, all things on the bridge port are set in
order)
When they are specified under the port:
we check if the bridge is up, if yes, and stp is already configured,
we process mstpctl settings
This check today only checks running stp_state
We should also check the user configured stp state for the bridge
Note that the problem exists only if the bridge and ports are
already up and user executes ifup again and when we need to re-evaluate
the bridge port settings
solution:
When the bridge port is being checked for mstp settings, not only
check running stp state, but also check user specified stp state and
correct bridge stp state before proceeding with mstp configuration
Few things to note with this patch:
- If user changed stp state on bridge to 'on', and did `ifup
<bridge_port>'`,
though the user has not ifup'ed the bridge yet, the bridge stp state
will be applied (very few people will run into this and practically this
should not be a problem atall. But from correctness POV it is
a voilation. ).
- To avoid this, the other solution would have been to let the bridge
port code be as is, but handle this during bringing up the bridge,
but, this can confuse the user, because when processing the
bridge_port, you will still throw warnings even if the port stp config
is later reapplied when the bridge comes up
- note that the patch only handles the case when stp state is not on and
somebody turned it on. For the case where stp state was on and somebody
turned it off, this patch wont throw warnings for the mstpctl config. But
it will not cause any issues because once stp is off things will be ok
everywhere. I want to keep any changes here out of this patch. I will
document this in the bug...and see if i can handle this in 2.5.5

add param in ifupdown2.conf to prevent fupdown2 users from specify interface config file on the CLI
Ticket: CM-7066
Reviewed By: scotte,roopa,olson
Testing Done: Unit testing and regression testing
This patch does two things:
1. It moves the interfaces config file name to the ifupdown2.conf file in /etc/network/ifupdown2.
This should allow administrators to specify a config file location different from the default and allow
subsets of users to use it without giving them access to specifying their own with the -i option in ifup/ifdown.
2. It also adds a new config setting called "disable_cli_interfacesfile" used to prevent users
from specifying their own interfaces file. This defaults to "1" (even if it is not configured).
Note: this new default takes away users ability to specify an interfaces file.
This should close the vulnerability where users could specify their own interfaces file
and add arbitrary user commands.
This leaves the shell=True option in the user commands add-on module since the ifup/ifdown/ifreload/ifquery
commands already require root access to run and the interfaces config file also requires root access to modify.
Currently, ifupdown implicitly configures pvid on a bridge port
in case user doesn't configure it. There is no way to configure
a bridge port to not accept untagged packets. The new option
allows user to do that without changing the current default
behavior.
The "ip batch command to add a bridge port and flush the dev" command with 1k netdevices was taking 1.4G of memory. With 2k netdevices batch, this command was causing a OOM condition. To avoid this, commit the batch after 250 ports. Ideally we have to look at the internal batch implementation to see if there is an underlying issue.

some notes from CCR:
ifreload was designed to be an optimization for 'service networking
restart' or 'ifdown -a + ifup -a'.
essentially it is a combination of 'ifdown + ifup' with some smarts in
which interfaces it will execute ifdown on.
By default it does the below:
ifdown all interfaces that were deleted from the interfaces file
ifdown all interfaces that were changed from the last time they were
ifup'ed
ifup -a (execute ifup on all interfaces marked auto)
Did not realize people will use ifreload as much as they do today. Also,
they may execute it on a production box when changes are made. ifdown on a production box can be
disruptive because if the ifdown which is part of the ifreload.
To have a non-disruptive option to ifreload, 2.5 added a new option -c
that only executed 'ifup' on all interfaces. Thus reloading all auto +
any other interfaces that were once brought up on the box (essentially
all interfaces present in the saved state file). This by default did not
do anything to the interfaces that got deleted from the file. But had an
ifupdown2.conf toggle to do so.
Looking at the evo use case, they do want to use a single command that
modifies, adds, deletes with
minimum disruption. we can achieve maybe what they want with multiple
commands (But there is also a case of a bug in the build evo is running
which makes it not so easy ).
This patch fixes the bug and also tries to change the default ifreload
behaviour controllable via a variable in ifupdown2.conf.
when ifreload_down_changed=0 in ifupdown2.conf, ifreload will only
ifdown interfaces that were deleted
from the file but not the ones that changed. subsequent ifup as part of
ifreload on the interfaces
that changed will apply the delta. And ifreload_down_changed default
value is '0'.
WIth the patch, ifreload by default will do the below (going back to the
previous default is just a toggle in the ifupdown.conf file):
ifdown all interfaces that were deleted from the interfaces file
ifup -a (execute ifup on all interfaces marked auto)
It sounds like a big change of behaviour for a hotfix release, but
essentially the patch just moves a few things around. And the change in
behaviour is so subtle that it is not very visible.
It just makes it non-disruptive.

failure, the "set -e" on line 3, the commands on lines 20 and 22 will
fail if the files being looked for do not exist, causing the script to
exit with a non-zero exit code. Causing apt to fail the upgrade.
The solution requires having the newer version of the ifupdown2 package
provide a preinst script that gets run before the older package's postrm
script is run[1,2]. This gives us the opportunity to quietly fix the
problem. We also fix the postrm script in newer versions of the package
so it cannot bomb out in this way.
Replaced vxlan-peernodeip attribute with vxlan-remoteip. Updated
the vxlan and iproute2 modules to configure head end replication
using bridge fdb commands.
Dont follow dependents during down of interfaces as part of ifreload
Ticket: CM-5571
Reviewed By:
Testing Done: tested ifreload with example in the bug
ifdown of the bridge svi was following the lowerdev and downing the
bridge. kernel implicitly deletes all svi's on bridge down.
ifup of the bridge usually handles it, but a change done in 2.5.1
was causing it not to. Thinking about this some more, its safe
to not follow dependents on down during a ifreload. This patch does
just that.
MTU settings are defaulted 1500 when interface is ifdowned.
This has the effect of changing the MTU on the interface and any subinterfaces to
1500. And if these subinterfaces are in a bridge, the bridge will pick the MIN MTU
so the bridge keeps this MTU even after the interface is brought back up. The sub
interface does not change to a higher value then 1500 (kernel VLAN driver only
moves the MTU is the decreasing direction.
1. Earlier various clag components where using link admin state for enforcing
proto_down. With the introduction of a seperate proto_down state this is no
longer needed. Now on clag bond "proto_down" the bond and its slaves are
explicitly placed in a proto_down state. This carrier downs the slaves and
oper-downs the clag-bond. Change has been done in clagd, clag-monit script and
bonding driver.
2. Earlier misc tricks where needed in ifupdown2 to prevent slave state changes
for clag bond outside of clagd. These tricks are no longer needed and have been
reverted to keep ifupdown2 handling simple/consistent. This change basically
reverts #6985e1a376b538fbfa2346ef657427ae7e8f117a.

Check for zero address on bridge ports before enslaving it to the bridge
Ticket: CM-4859, CM-4382
Reviewed By:
Testing Done: Tested with config which included bond bridge ports with
zero address on the bond.
The bridge driver rejects the port add with -EINVAL.
A bond with no slaves is one usecase where the bond interface
has a zero hw address and is rejected by the bridge.
EINVAL currently is very confusing.
This patch checks for a valid ether add before enslaving the port to the
bridge.

Move clag_enable setting to ifupdown2 ifenslave.
Ticket: CM-4802
Reviewed By:
Testing Done: yes
1. clag_enable needs to be set before slaves are added to the bond. Otherwise
bonding driver will bring the slaves up independent of clagd.
2. also added post_down clagd addon to cleanup the clag-id on ifdown.
1. For clag bonds the slaves are kept down under various conditions (when clagd
is holding the bond in an errDisabled state). ifupdown2 should not set the slave
states for clag bonds.
2. Bonding driver sets the slave states on enslave and release (also for
non-clag bonds) so ifupdown2 doesn't need to set the slave state.
On tunnel delete, tunnel termination object in BCM sdk is not cleaned properly.
As a result, mpls_entry in the hardware is left around even though software has
deleted the tunnel. This prevents subsequent dynamic creation of the same tunnel
and also mac learning, as mpls_entry points to invalid SVP with no CML setting
to do hardware learning.
Also, changes in ifupdown2 to make "vxlan-learning on" as default, so that
user/script doesn't have to explicitly turn on the learning.
