There's a chance that not backporting 111e6b45315c (selftests/bpf: make test_verifier run most programs) will cause possible bugs on the changes added by a25d38b54163 (bpf: relax verifier restriction on BPF_MOV | BPF_ALU) to remain uncaught. + + ------------------------------------------------ ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-1040-gke 4.15.0-1040.42 ProcVersionSignature: Ubuntu 4.15.0-1040.42-gke 4.15.18 Uname: Linux 4.15.0-1040-gke x86_64 ApportVersion: 2.20.9-0ubuntu7.7 Architecture: amd64 Date: Wed Aug 21 15:09:32 2019 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=C.UTF-8 SHELL=/bin/bash SourcePackage: linux-signed-gke-4.15 UpgradeStatus: No upgrade log present (probably fresh install)
