CI failure is being fixed in #3909. Once that one is merged, we need to rebase this PR. |

We do not use all the files from scripts, only seccomp.sh and lib.sh. This prevents unneeded rebuild of the image if e.g. scripts/release_build.sh has changed. Signed-off-by: Kir Kolyshkin <[email protected]> (cherry picked from commit d542ad6)
Dockerfile used to install libseccomp-dev packages for different architectures. This is no longer true since commit f30244e, which changed to cross-compiling libseccomp (so we can get a static library to link against). Thus, adding extra architectures is no longer needed. Signed-off-by: Kir Kolyshkin <[email protected]> (cherry picked from commit 476aa18)
All we need is gcc, libc-dev, and binutils. In addition to that, crossbuild-essential installs g++, libstdc++-dev, and a bunch of perl packages and libraries which we do not need. This should speed up image building, as well as make it smaller. Signed-off-by: Kir Kolyshkin <[email protected]> (cherry picked from commit f0f1b5f)
LDFLAGS_COMMON are used from two places, so it makes sense to dedup. LDFLAGS_STATIC is a preparation for the next commit. Signed-off-by: Kir Kolyshkin <[email protected]> (cherry picked from commit f2f6e59)
1. Set to empty value by default. 2. Assume Linux (remove GOOS check, since we do not support other OSes). 3. Instead of using a "not-supported" list, use a "supported" list (as Go release notes usually say which platforms are supported). As of today, -buildmode=pie is supported for: * linux/386, linux/amd64, linux/arm, linux/arm64, and linux/ppc64le (since Go 1.6, see https://tip.golang.org/doc/go1.6#compiler) * linux/s390x (since Go 1.7, which adds the initial port) * linux/riscv64 (since Go 1.16, see https://tip.golang.org/doc/go1.16#riscv) NOTE this does not mean we support these architectures; it is merely a way to see if -buildmode=pie can be used.

It doesn't matter whether static or dynamic linking is used, runc always needs libcontainer/nsenter, which is written in C and thus requires cgo. Same is true for libcontainer/integration. In addition, contrib/pkg/seccompagent also needs cgo (if seccomp build tag is set), as it need to be linked against libseccomp C library. By default, cgo is disabled when cross-compiling, meaning that CGO_ENABLED=1 has to be set explicitly in such cases. In all other cases (e.g. other contrib binaries) we do not need cgo. Remove CGO_ENABLED=1 from GO_BUILD_STATIC (as it does not have anything to do with static linking), and add it to all targets that require it.

This is necessary for running on RISC-V using K3s.
Many projects - including K3s - depend on runc 1.1.x, so waiting for a 2.0.x release and then porting to any changes introduced may probably be a much larger effort. This includes all changes done in #3446, which are really minimal but necessary to support the new architecture.
With this patch I have successfully compiled and run K3s on a RISC-V QEMU VM and have verified that I can create Pods.
