I am developing an UEFI App that will need to perform a GET request through http.
As a start up point, I want to make sure my setup is working properly so that the http requests can actually go through.
To that end, I spent the last few days trying to make the http command work in the EFI Shell launched inside QEMU.
I can get the ping command to work properly, but calling:
http httpbin.org/get
Always returns:
Unable to open http protocol on `eth0` - Unsupported
Unable to download the file `/get` on `eth0` - Unsupported
This is my startup.nsh script to configure the EFI Shell's interface:
connect
ifconfig -r eth0
ifconfig -s eth0 dhcp
ifconfig -l eth0
These were my different attempts at invoking Qemu properly:
-netdev user,id=mynet0,hostfwd=tcp::8080-:80 -device e1000,netdev=mynet0 \
-netdev user,id=user.0 -device e1000,netdev=user.0 \
-nic user,ipv6=off,model=e1000,mac=52:54:98:76:54:32 \
And following this guide I tried to setup a tap, albeit without luck, I'd launch qemu with the following configuration:
-netdev tap,id=mynet0,ifname=tap0,script=no,downscript=no -device e1000,netdev=mynet0,mac=52:55:00:d1:55:01 \
Do you have any clue what step am I missing?
Where do you believe I could be failing in making eth0 supported?
Is the tap crucial?
Are you able to make this setup work on your side?
Update:
Very good suggestion @MiSimon, I hadn't realized that the HttpDxe driver wasn't being built with the OvmfPkg.
I have now added its INF to OvmfPkgX64.dsc and OvmfPkgX64.fdf.
Although, running drivers is displaying a duplicate entry:
0000000A D - - 1 - HttpDxe HttpDxe
0000000A ? - - - - HttpDxe HttpDxe
With respect to calling the http command, the error has progressed to:
Downloading 'http://httpbin.org/get'
Unable to download the file '/get' on 'eth0' - Unsupported
The debug log shows:
HttpNotify: Event - 0, EventStatus - Unsupported
Error: Could not retrieve the host address from DNS server.
The tool requires nearly all network drivers to be loaded.
Make sure your image contains the following drivers:
All of them are can be found in EDK2 inside the NetworkPkg.
