Hi,

We saw similar issue in bug 1169467.
Can you help to double confirm
1. Is it always failed for Z3 to send MMS over T-Mobile network no matter what multimedia content you have attached?
2. Can you help to collect main, radio logcat and tcpdump for further clarification by following the instruction in https://github.com/bevis-tseng/Debug_Tools?

Thanks!

Yes, I am seeing this happen with .jpg images, .mp3 audio files, and .3gp video files

I am attaching the tcpdump and logcats now.

Hi Martin,

It seems that you attached the command file instead of the capture.pcap file.

Can you help to provide the correct one?

Thanks!

I have a rildebug version that he can use.

Marty, please use this build to provide Bevis with the information he requires.

Here is the requested file.  I let it run for about 30 seconds after reproducing the bug so hopefully it caught all information you needed.

After checking the logs, the root cause seems the same to what we've seen in bug 1169467 comment 41.

We have to figure a way to have a test build with MTU correctly configured for sending MMS to see if we won't get any complaint about "Packet Too Big" anymore.

netd (KitKat) supports the following command :
"interface setmtu <interface> <val>"
we could add a path to send this command to netd.

However, I wonder why this doesn't happen on Flame...

What I have found so far is that, according to the log/tcpdump in bug 1169467 comment 21 and bug 1169467 comment 22 and the information in [1] , this works on flame because only ipv4 available in Flame device. :(

Thanks Bevis, it makes sense then. 

Path MTU Discovery should be enabled by default for IPv6, but I am not sure if it's working on AOSP. This blogs [1] says that setting 'net.ipv4.tcp_mtu_probing' affects ipv6 connections as well, maybe it worths a try. Another option is to use IPv6 default minimum MTU (1280) for ipv6 connections.

Could one of you please take this?

	Bevis Tseng[:bevis][:btseng](Exited) Assignee
	Comment 17 • 9 years ago

I'll take this to follow up.
We can have a short-term solution to set MTU to 1280 for IPv6 and adopt the MTU from either apn settings or the one reported from modem for long-term solution.

	Comment 18 • 9 years ago

Just to let you know, we are considering disabling ipv6 on Aries/Shinano, please see bug 1171185 comment 21, so this issue will no longer exist if we use ipv4 only.

This bug is fixed by the fix for bug 1171185. The fix has just landed, we can verify this on next nightly that contains the fix.

I just tried this on my Aries device/TMobile SIM and it is still not working for me.

I confirmed with nhirata that I need to do a full flash instead of shallow, so will have to try again once I do that.

Confirming what marcia is stating in comment 22, the verify performed above was conducted on a full flash of the latest Aries build available to us by dogfood-debug.

	Marcia Knous [:marcia]
	Comment 25 • 9 years ago

Just tested after a full flash, confirming I can send an MMS successfully.
