[Bug 1749058] Re: incorrect source address in IGMP Membership Report messages
I'm sorry, I tried 4.16.0-rc2 when I got to physically access the server in the PoC cluster this morning, but the driver called "hpsa" for the RAID controller didn't work in the boot-up phase, I guess it could've possibly been because of the failed hard disk drive in the array of RAID 1. I had to roll back to 4.13.0 that comes with the HWE package in Ubuntu 16.04, but I'd like to try to run the new kernel and see if it does fix the problem so I'm going to do it on my laptop this weekend.

[Bug 1749058] Re: incorrect source address in IGMP Membership Report messages
I think I should also have mentioned that I had tried a couple of things all in vain, they all resulted in the same unchanged value at source address field in the IGMP packets: 1) A route-map in quagga: ip prefix-list p4-multicast seq 5 permit 224.0.0.0/4 ! route-map filter-multicast-4 permit 10 match ip address prefix-list p4-multicast set src 10.0.0.48 ! route-map set-src permit 10 set src 10.0.0.48 ! ip protocol any route-map filter-multicast-4 2) A route directly in the linux routing table: ip route replace 224.0.0.0/4 src 10.0.0.48 dev fabric1 3) A SNAT line in iptables: iptables -t nat -A POSTROUTING --dst 224.0.0.0/4 -j SNAT --to-source 10.0.0.48 Thank you, Gunwoo -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1749058 Title: incorrect source address in IGMP Membership Report messages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1749058/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1749058] Re: incorrect source address in IGMP Membership Report messages
apport information
** Tags added: apport-collected xenial
** Description changed:
I found that linux kernel had had a bug in the implementation of IGMP
membership report packet generation. the RFC documents for IGMP version 2
and 3 says that you must ignore the reports with a source ip address that
you can't identify as belonging to a network assigned to the interface on
which the packet was received. and the networking OS in the ToR switch,
Force10 OS 9 does ignore it.
I've also figured out a patch has been made for this bug in Linus's Github.
and there was a mark on Github that reads "v4.16-rc1". (
https://github.com/torvalds/linux/commit/a46182b00290839fa3fa159d54fd3237bd8669f0
)
I honestly have no idea how Ubuntu LTS team works with regard to this kind
of patches from the fresh new upstream version of linux kernel. hope you
guys will easily fix it for people like me who has no experience at
building and distributing custom built kernels over a few servers.
Test environment:
I used two ToR switches and one linux machine for this test.
I only used 2 ethernet ports on the linux machine.
There was a recent version of Ubuntu with HWE kernel. I'm not sure if
no-HWE one would be the same case - the version of linux-generic-hwe-16.04
was 4.13.0.32.52 -
To test networking router stuff, I used the quagga from Cumulus Routing on
the Host 3.3.2 (
https://cumulusnetworks.com/products/cumulus-routing-on-the-host/#roh-download-section
)
What I did and saw in my case:
1. set a network interface (A) so it gets an IPv4 address, but also in vain
issue "ip link set ${if_name} multicast off"
2. assign an IPv4 address to another network interface (B), but in this
case with a 31-bit-long subnet mask length.
3. install quagga from cumulus, launch zebra and pimd, issue "ip pim sm" in
the interface configuration mode for the interface (B) with a 31-bit-long
subnet mask length
4. I checked that the source IP address part of the IGMP membership report
packets from the linux machine is the address I assigned to the network
interface (A) with 27-bit-long subnet mask -using dumpcap and tshark-, and
that the PIM service on the switch ignored the Reports printing debugging
messages including : "Invalid sender address"
affects ubuntu

[Bug 1749058] Re: incorrect source address in IGMP Membership Report messages
I'm sorry that I confused with the IGMP service with the PIM service on Dell FTOS 9, which printed the debugging message "Invalid sender address" and I think you can just test the igmp connection by issuing "ping 224.0.0.1" instead of installing quagga and launching pimd.
