FS#2371 - Multicast/IGMP/DSA Issues

- Device problem occurs on

Linksys WRT3200ACM

- Software versions of OpenWrt/LEDE release, packages, etc.

Latest trunk (with 4.19 kernel)

I have enabled DSA in my router with the kernel version 4.14, and it worked well, but since the kernel was bumped to 4.19 DSA has been giving some issues, namely:

- When I add a interface, for example a DHCP client and select for the interface wan.12 OpenWRT crashes and bootloops until it reboots to the last system. After some testing I found out that if I added a interface connected to wan and thern connect the mentioned DHCP client interface to wan.12 the system doesn’t crash

-When I have the system working and connect a IPTV STB to the lan interface, with the exact configuration as in kernel 4.14 the TV works for a while but then image stops. After some testing found out that only the channel that stopped wouldn’t work, while other channels worked, until they stopped working (the same issue as the first channel) and it goes on and on and on until either something (I don’t know what) times out or I restart the router.

This only happened after the kernel 4.14 bump, and I believe this issue also happens with Turris omnia devices.
If you need I’m currently able to test patches as you need.
My question is, Is this a OpenWRT bug or a device drive issue that must be reported to the kernel develp team?
Either way I’m posting the same in the forums.

OpenWRT crashes

Please ideally provide the exact steps to reproduce the issue and complete crashlog.

Steps for the Vlan bug:

  1. Flash a OpenWRT image with the latest trunk
  2. Create a bridge connected to a vlan interface (for example wan.12)
  3. Apply the configuration
  4. The system will bootloop until it boots to the other partition or if you're lucky it will discard changes and restore your previous settings

Workaround for the Vlan bug:

  1. Create a dummy bridge interface connected to a interface without vlan (for example wan)
  2. Apply the configuration
  3. Create the bridge you need connected to the vlan interface (for example wan.12)
  4. Apply the configuration
  5. Now the interface works as expected

Steps for the bridge bug:

  1. Create a bridge connected to a vlan interface (for example wan.12) and to a interface without vlan (for example lan1)
  2. If a device is connected it won't get any trafic/be able to comunicate with devices on the other vlan's network (vlan 12)

Steps for the IPTV bug:

  1. Use the default OpenWRT configuration
  2. Install omcproxy
  3. Connect any STB to the lan and the TV will stop randomly ant no specific time, but if you change channels it returns to normal

About the crashlogs I can't take one from my device but a forum member posted this one on a device with similar specs:

I believe I have found something
http://lists.openwrt.org/pipermail/openwrt-devel/2019-March/016332.html 7

I tried the same steps in this website and the symptoms are the same!

Also, just found out that the issue is related to vlan filtering in the bridge, when I compiled a openwrt version with it disabled the issue is gone!

This patch fixed vlan interfaces for me:

https://lore.kernel.org/patchwork/patch/1043590/

But the issue with IPTV and vlan interface to non-vlan interface bridging doesn't work.
