Hello,
currently i'm running vanilla 3.8.8 kernel with some tap devices using
VLANs on top of a bridge on top of a bond.
This works fine and everything is great.
Now i started to test 3.10.9 and all my VLANs stopped working no matter
i disable or enable CONFIG_BRIDGE_VLAN_FILTERING.
The packets never reach the TAP device.
Here is an output of ip a l (vlan 3021):

Just enabling config option doesn't turn on the filtering behavior.

I can only guess that the configuration based on the above data. Can
you give a diagram of the config.
On the off chance that you are actually trying to configure vlan
filtering, can you give this patch a try (net-2.6 tree):
Author: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp>
Date: Tue Aug 20 17:10:18 2013 +0900
bridge: Use the correct bit length for bitmap functions in the VLAN
code
I don't think it made it to stable yet.
Thanks

Sure:
# brctl show
bridge name bridge id STP enabled interfaces
vmbr0 8000.00259084dea8 no bond0
tap320i0
vmbr1 8000.00259084deaa no bond1
vmbr1v3021 8000.00259084deaa no tap320i1

I addd that patch and now the vlan stuff works at least on the host
node. But my tap devices still don't work.
I also tried to attach the tap device on top of a vlan attached to bond1
but then gvrp does not work anymore. The kernel announces gvrp once and
then does not answer the query packets from the switch.

vmbr1v3021 (bridge)
/ \
tap320i1 vmbr1.3021 (vlan)
\
vmbr1 (bridge)
\
bond1
\
eth X
Is that right? Is this the setup that has the problem you are
describing?

In my attempts to reproduce your problem I didn't configuring filtering
on the upper bridge, but that is what could have been causing
your problem. I'll attempt it and let you know.

Can you provide the filtering settings for both bridges you use?

I don't filter at all right now it's compiled in but not enabled - but i
have these problems since these patches were included.
It only start to work if i set the eth0 and eth1 (slaves of the bond) to
promisc mode. So the problem seems to be that the ethernet devices do
not accept the VLAN tagged packages.

That doesn't make much sense. If the filtering is not enabled, then
this code isn't in use. It will not try to set any vlan filtering
so you should be running with essentially stock bridge.
Bridge sets promisc mode on all its ports, so your bond device should
be in promisc mode. Bonding code sets different set of slaves into
promisc mode depending on the mode you use. Which mode do you have
your bond configured in?
Does, dmesg tell you if devices have entered promisc mode?
