2022-05-04	wireguard: selftests: set panic_on_warn=1 from cmdline	Jason A. Donenfeld	1	-1/+1
	Rather than setting this once init is running, set panic_on_warn from the kernel command line, so that it catches splats from WireGuard initialization code and the various crypto selftests. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-05-06	wireguard: selftests: use normal kernel stack size on ppc64	Jason A. Donenfeld	1	-0/+1
	While at some point it might have made sense to be running these tests on ppc64 with 4k stacks, the kernel hasn't actually used 4k stacks on 64-bit powerpc in a long time, and more interesting things that we test don't really work when we deviate from the default (16k). So, we stop pushing our luck in this commit, and return to the default instead of the minimum. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-12-16	wireguard: selftests: import harness makefile for test suite	Jason A. Donenfeld	1	-0/+12
	WireGuard has been using this on build.wireguard.com for the last several years with considerable success. It allows for very quick and iterative development cycles, and supports several platforms. To run the test suite on your current platform in QEMU: $ make -C tools/testing/selftests/wireguard/qemu -j$(nproc) To run it with KASAN and such turned on: $ DEBUG_KERNEL=yes make -C tools/testing/selftests/wireguard/qemu -j$(nproc) To run it emulated for another platform in QEMU: $ ARCH=arm make -C tools/testing/selftests/wireguard/qemu -j$(nproc) At the moment, we support aarch64_be, aarch64, arm, armeb, i686, m68k, mips64, mips64el, mips, mipsel, powerpc64le, powerpc, and x86_64. The system supports incremental rebuilding, so it should be very fast to change a single file and then test it out and have immediate feedback. This requires for the right toolchain and qemu to be installed prior. I've had success with those from musl.cc. This is tailored for WireGuard at the moment, though later projects might generalize it for other network testing. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: David S.
