Below race can come, if trace_open and resize of cpu buffer is running parallely on different cpus CPUX CPUY ring_buffer_resize atomic_read(&buffer->resize_disabled) tracing_open tracing_reset_online_cpus ring_buffer_reset_cpu rb_reset_cpu rb_update_pages remove/insert pages resetting pointer This race can cause data abort or some times infine loop in rb_remove_pages and rb_insert_pages while checking pages for sanity. Take ring buffer lock in rb reset to avoid resetting of cpu buffer. Change-Id: I1d3344cca99e936d4e04a0e430e0ef9a975404c8 Signed-off-by: Gaurav Kohli <gkohli@codeaurora.org> |
