The commands used were (roughly): hack/pin-dependency.sh github.com/opencontainers/runc v1.0.0 hack/lint-dependencies.sh # Follow its recommendations. hack/pin-dependency.sh github.com/cilium/ebpf v0.6.1 hack/pin-dependency.sh github.com/opencontainers/selinux v1.8.2 hack/pin-dependency.sh github.com/sirupsen/logrus v1.8.1 # Recheck. hack/lint-dependencies.sh GO111MODULE=on go mod edit -dropreplace github.com/willf/bitset hack/update-vendor.sh # Recheck. hack/lint-dependencies.sh hack/update-internal-modules.sh # Recheck. hack/lint-dependencies.sh [v2: rebased, updated runc 3a0234e1fe2e82 -> 2f8e8e9d977500] [v3: testing master + runc pr 3019] [v4: updated to 93a01cd4d0b7a0f08a] [v5: updated to f093cca13d3cf8a484] [v6: rebased] [v7: updated to runc v1.0.0] [v8: rebased] Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
