From 7fb0a5ee8889488f7568ffddffeb66ddeb50917e Mon Sep 17 00:00:00 2001 From: "Nikunj A. Dadhania" Date: Mon, 9 Apr 2012 13:52:23 +0530 Subject: perf kvm: Finding struct machine fails for PERF_RECORD_MMAP Running 'perf kvm --host --guest --guestmount /tmp/guestmount record -a -g -- sleep 2' Was resulting in a segfault. For event type PERF_RECORD_MMAP, event->ip.pid is being used in perf_session__find_machine_for_cpumode, which is not correct. The event->ip.pid field happens to be 0 in this case and results in returning a NULL machine object. Finally, access to self->pid in machine__mmap_name, results in a segfault later. For PERF_RECORD_MMAP type, pass event->mmap.pid. Signed-off-by: Nikunj A.
