Merge branch 'bpf-add-support-for-sys-enter-exit-tracepoints'
Yonghong Song says: ==================== bpf: add support for sys_{enter|exit}_* tracepoints Currently, bpf programs cannot be attached to sys_enter_* and sys_exit_* style tracepoints. The main reason is that syscalls/sys_enter_* and syscalls/sys_exit_* tracepoints are treated differently from other tracepoints and there is no bpf hook to it. This patch set adds bpf support for these syscalls tracepoints and also adds a test case for it. Changelogs: v3 -> v4: - Check the legality of ctx offset access for syscall tracepoint as well. trace_event_get_offsets will return correct max offset for each specific syscall tracepoint. - Use variable length array to avoid hardcode 6 as the maximum arguments beyond syscall_nr. v2 -> v3: - Fix a build issue v1 -> v2: - Do not use TRACE_EVENT_FL_CAP_ANY to identify syscall tracepoint. Instead use trace_event_call->class. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
