Title: powerpc/perf: Cap 64bit userspace backtraces to PERF_MAX_STACK_DEPTH Status in linux package in Ubuntu: In Progress Status in linux-lts-utopic package in Ubuntu: Invalid Status in linux source package in Trusty: Fix Released Status in linux-lts-utopic source package in Trusty: Fix Released Status in linux source package in Utopic: Fix Released Status in linux-lts-utopic source package in Utopic: Invalid Status in linux source package in Vivid: In Progress Status in linux-lts-utopic source package in Vivid: Invalid Bug description: Cap 64bit userspace backtraces to PERF_MAX_STACK_DEPTH We cap 32bit userspace backtraces to PERF_MAX_STACK_DEPTH (currently 127), but we forgot to do the same for 64bit backtraces. If userspace creates a stack frame that points to itself we will loop forever in the backtrace code with interrupts off.
