<title>selftests: mirror_gre_bridge_1q: Avoid changing PVID while interface is operational</title>

<content type='text'>
In emulated environments, the bridge ports enslaved to br1 get a carrier
before changing br1's PVID. This means that by the time the PVID is
changed, br1 is already operational and configured with an IPv6
link-local address.

When the test is run with netdevs registered by mlxsw, changing the PVID
is vetoed, as changing the VID associated with an existing L3 interface
is forbidden. This restriction is similar to the 8021q driver's
restriction of changing the VID of an existing interface.

Fix this by taking br1 down and bringing it back up when it is fully
configured.

With this fix, the test reliably passes on top of both the SW and HW
data paths (emulated or not).

<title>selftests: forwarding: Use same VRF for port and VLAN upper</title>

The test creates a separate VRF for the VLAN upper, but does not destroy
it during cleanup, resulting in "RTNETLINK answers: File exists" errors.

Fix by using the same VRF for the port and its VLAN upper. This is OK
since their IP addresses do not overlap.

no 'host' can communicate (ping) through a locked port unless the
MAC address of the 'host' interface is in the forwarding database of
the bridge.

<title>net/sched: act_police: more accurate MTU policing</title>

<id>4ddc844eb81da59bfb816d8d52089aba4e59e269</id>
<content type='text'>
in current Linux, MTU policing does not take into account that packets at
the TC ingress have the L2 header pulled. Thus, the same TC police action
(with the same value of tcfp_mtu) behaves differently for ingress/egress.
In addition, the full GSO size is compared to tcfp_mtu: as a consequence,
the policer drops GSO packets even when individual segments have the L2 +
L3 + L4 + payload length below the configured valued of tcfp_mtu.

Improve the accuracy of MTU policing as follows:
 - account for mac_len for non-GSO packets at TC ingress.
 - compare MTU threshold with the segmented size for GSO packets.
Also, add a kselftest that verifies the correct behavior.

Add a test that checks that pedit adjusts source and destination
addresses of IPv4 and IPv6 packets.

Output example:

$ ./pedit_ip.sh
TEST: ping                                                          [ OK ]
TEST: ping6                                                         [ OK ]
TEST: dev swp2 ingress pedit ip src set 198.51.100.1                [ OK ]
TEST: dev swp3 egress pedit ip src set 198.51.100.1                 [ OK ]
TEST: dev swp2 ingress pedit ip dst set 198.51.100.1                [ OK ]
TEST: dev swp3 egress pedit ip dst set 198.51.100.1                 [ OK ]
TEST: dev swp2 ingress pedit ip6 src set 2001:db8:2::1              [ OK ]
TEST: dev swp3 egress pedit ip6 src set 2001:db8:2::1               [ OK ]
TEST: dev swp2 ingress pedit ip6 dst set 2001:db8:2::1              [ OK ]
TEST: dev swp3 egress pedit ip6 dst set 2001:db8:2::1               [ OK ]
