Hi all,
I face some strange issues with SSH/SCP/SFTP connection hangs on a 3B+. While transfering a huge file to a Linux Server, the connection hangs. I do observe this 100% time, when the file is like 1Gb or more I never observed this with smaller files, like RPMS.
After some googling, I found the following threads: https://github.com/raspberrypi/linux/issues/2449 https://github.com/raspberrypi/linux/issues/2482
Made some attempts this morning, and I can confirm that I face the 1st one. I have no time, yet, to check the 2nd thread.
OK. Both threads tend to indicate that TSO should be disabled, by default: sudo |ethtool -K eth0 tx-tcp-segmentation off| and it works perfectly ...
Any chance to have the patch reported to CentOS ? https://github.com/raspberrypi/linux/commit/d3b70445bcf2ab9b132138dc1d320a28...
Regards,
Stephan, we are waiting for the raspberrypi kernel to be updated to 4.14.51 (or 52) to fix some CVEs. Once they do that, since the patch you mentioned has already been pushed, it should be automatically picked up.
Pablo.

OK. Thx Pablo,
Just to know if I have to impletement a small workaround for our needs or wait for this kernel, do you have an idea when this kernel will come ? 1 week, 2 weeks, 1 month, more, less ?
Thx.

The truth is, we don't know, but rather soon. Since we already decided to make this new kernel (due to CVE), we are actually waiting for the raspberrypi kernel to be updated so we can release our generic and raspberrypi kernels in sync. As soon as they update, we should have a kernel to test within a few days.

I checked today and RPI foundation rebased to 4.14.52 (skipping 4.14.51) : https://github.com/raspberrypi/linux/commits/rpi-4.14.y
So I bumped the release and newer rpi kernel (that works on rpi2/rpi3/rpi3b+) has been built.
If people can give feedback on the following kernel, we can then proceed with sign+push to official mirrors. Here is where the (unsigned) pkgs are located : https://buildlogs.centos.org/c7-kernels.armhfp/raspberrypi2/20180628075123/4...
Cheers,

I just tested the huge file transfer via SCP, with a few different scripts. Issue fixed on my side.
Thx for all.
