When pstore_post_reboot test gets skipped because of unmet dependencies and/or unsupported configuration, it returns 0 which is treated as a pass by the Kselftest framework. This leads to false positive result even when the test could not be run. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run.

Modern distroes increasingly make use of BPF programs. Default Ubuntu 18.04 installation boots with a number of cgroup_skb programs loaded. test_offloads.py tries to check if programs and maps are not leaked on error paths by confirming the list of programs on the system is empty between tests. Since we can no longer expect the system to have no BPF objects at boot try to remember the programs and maps present at the start, and skip those when scanning the system.

2018-06-13tools/bpftool: fix a bug in bpftool perfYonghong Song1-2/+3
Commit b04df400c302 ("tools/bpftool: add perf subcommand") introduced bpftool subcommand perf to query bpf program kuprobe and tracepoint attachments. The perf subcommand will first test whether bpf subcommand BPF_TASK_FD_QUERY is supported in kernel or not. It does it by opening a file with argv[0] and feeds the file descriptor and current task pid to the kernel for querying. Such an approach won't work if the argv[0] cannot be opened successfully in the current directory. This is especially true when bpftool is accessible through PATH env variable. The error below reflects the open failure for file argv[0] at home directory. [yhs@localhost ~]$ which bpftool /usr/local/sbin/bpftool [yhs@localhost ~]$ bpftool perf Error: perf_query_support: No such file or directory To fix the issue, let us open root directory ("/") which exists in every linux system. With the fix, the error message will correctly reflect the permission issue.
