Ian Rogers b01a706f9e perf bpf-event: Fix use-after-free in synthesis ... [ Upstream commit d7b67dd6f9 ] Calls to perf_env__insert_bpf_prog_info may fail as a sideband thread may already have inserted the bpf_prog_info. Such failures may yield info_linear being freed which then causes use-after-free issues with the internal bpf_prog_info info struct. Make it so that perf_env__insert_bpf_prog_info trigger early non-error paths and fix the use-after-free in perf_event__synthesize_one_bpf_prog. Add proper return error handling to perf_env__add_bpf_info (that calls perf_env__insert_bpf_prog_info) and propagate the return value in its callers.
