Description

HTTP download of a small file from the webserver stalls, while large file works flawlessly.

Setup is as follows:

  • Embedded Router, Gluon, batman-adv 2016.5

connected to Gateway via Ethernet (1500 MTU), speaking BATMAN IV

  • Gatway, batman-adv 2017.0

connected to Webserver via Ethernet (1500 MTU), reachable via Routing

  • Webserver

ships Firmware manifests and updates

Since upgrading to batman-adv 2017.0 on the gateway our autoupdater is unable to download its update manifest, a downgrade to 2016.5 resolved this.

I've attached pcaps of the upper (bat0) and lower (bat0 slave interface) interfaces of both router and gateway, as well as the file that fails to download.
