[PATCH] bridge: separate querier and query timer into IGMP/IPv4 and MLD/IPv6 ones
Currently we would still potentially suffer multicast packet loss if there
is just either an IGMP or an MLD querier: For the former case, we would
possibly drop IPv6 multicast packets, for the latter IPv4 ones. This is
because we are currently assuming that if either an IGMP or MLD querier
is present that the other one is present, too.
This patch makes the behaviour and fix added in

[Bridge] VLAN-aware multicast querier after if link up
...to do multicast querying for some vid. This then does
not work for ports that come up later. It works only for those ports
that were already up when I set the global vlan options.
Debugging through the kernel I can see that the timers are simply never
started. Unless I disable and re-enable the querier for that particular vid.
Admittedly, I'm working with 5.15 at the moment. But even on mainline, I
do not see any relevant changes that would make this work.
I have a simple-ish patch, but I'm wondering whether I'm missing
something? Is maybe some action from userspace expected when...

[Bridge] [Patch net] bridge: do not expire mdb entry when bridge still uses it
From: Cong Wang <amwang at redhat.com>
This is a long-standing bug and reported several times:
https://bugzilla.redhat.com/show_bug.cgi?id=880035
http://marc.info/?l=linux-netdev&m=136164389416341&w=2
This bug can be observed in virt environment, when a KVM guest
communicates with the host via multicast. After some time (should
be 260 sec, I didn't measure), the multicast

[Bridge] bride: IPv6 multicast snooping enhancements
...anges I would like to submit to increase
the usefulness of the multicast snooping of the bridge code.
The first patch is an unaltered one I had submitted before, but since it
got no feedback I'm resubmitting it here for net-next. With the recently
added patch to disable snooping if there is no querier (b00589af + 248ba8ec05
+ 8d50af4fb), it should be a safe choice now (without these, patch 1/2 would
have introduced another potential for lost IPv6 multicast packets).
Both conceptually and also with some testing and fuzzing, I couldn't spot
any more causes for potential packet loss. And since...

query account expired state
...which, as far as I can tell,
> Samba knows nothing about.
The unfortunate situation is that Samba (4.19.2) does not implement the
'ADS_UF_PASSWORD_EXPIRED' flag. It does support
'msDS-UserPasswordExpiry', but that returns and LDAP time value so it
requires computation by the querier to figure out expiry.
Another suggestion from ldapwiki.com: "All expired user accounts:
'(&(objectCategory=Person)(objectClass=User)(!accountExpires=0)(!accountExpires=9223372036854775807))'"
does not work either. Accounts on Samba always have the value

I am on 4.18.8 and that doesn't have 'msDS-UserPasswordExpiry' or
'ms-DS-User-Password-Expired', but if it did, then the time stored
would be, as you say, in Windows format.

Re: multicast traffic no longer working after reboot
...I seem to have found the cause of the issue
but I'm not sure what the proper fix is.
The cause seems to be a kernel "regression":
https://bugzilla.redhat.com/show_bug.cgi?id=880035#c56
It seems that multicast now requires explicitly setting
/sys/class/<bridge>/bridge/multicast_querier to 1.
What is puzzling about this is that im wonder why this behavior
changeing patch was included in the RHEL/CentOS kernel. This is the
first time I ever ran into this kind of problem and previously multicast
seemed to work just out of the box.
The other issue is that I'm not sure how to ma...

[Bridge] [RFC PATCH net-next 0/5] Add layer 2 miss indication and filtering
tl;dr
=====
This patchset adds a single bit to the skb to indicate that a packet
encountered a layer 2 miss in the bridge and extends flower to match on
this metadata. This is required for non-DF (Designated Forwarder)
filtering in EVPN multi-homing which prevents decapsulated BUM packets
from being forwarded multiple times to the same multi-homed host.

KVM networking issue
Hi Mike,
Thanks for the info. I'd rather run monitoring such as tcpdump from
the VM if possible and not the host as a simulation of a network
appliance and with the intent eventually of giving others access to
the VM and not the host. Here is the xml file for the private network:
