From 3c4fc7bf4c9e66fe71abcbf93f62f4ddb89b7f15 Mon Sep 17 00:00:00 2001 From: David Gow Date: Fri, 23 Sep 2022 13:00:39 +0800 Subject: kunit: tool: Don't download risc-v opensbi firmware with wget When running a RISC-V test kernel under QEMU, we need an OpenSBI BIOS file. In the original QEMU support patchset, kunit_tool would optionally download this file from GitHub if it didn't exist, using wget. These days, it can usually be found in the distro's qemu-system-riscv package, and is located in /usr/share/qemu on all the distros I tried (Debian, Arch, OpenSUSE). Use this file, and thereby don't do any downloading in kunit_tool. In addition, we used to shell out to whatever 'wget' was in the path, which could have potentially been used to trick the developer into running another binary. By not using wget at all, we nicely sidestep this issue.
