I am glad that it was not just me being blind, then. ;-) And thank you for trying this out! > I'm probably doing something wrong but all the tests say that init > segfaulted in the log file: > > [ 5.505986] init[1]: segfault at 28 ip 000000000040101f sp 00007fff1bbf6fc0 error 4 in init[101f,401000+1000] likely on CPU 12 (core 12, socket 0) > [ 5.509949] Code: Unable to access opcode bytes at 0x400ff5. > [ 5.512314] coredump: 1(init): over coredump resource limit, skipping core dump > [ 5.514976] coredump: 1(init): coredump has not been created, error -7 > [ 5.516911] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b You are right, that is not the expected result. > Pasting the command output: > > $ tools/testing/selftests/rcutorture/bin/kvm.sh --allcpus --duration 1m --configs "2*TREE01" --trust-make > tools/testing/selftests/rcutorture/initrd/init already exists, no need to create it There was already an "init" program, so one thing to try is to remove it and re-run. The kvm.sh script will then rebuild it. I just tried that in case some recent change made this fail to work, and it "worked for me": Creating a statically linked C-language initrd Done creating a statically linked C-language initrd I will also be testing next-20240821 in case it magically got better.
