perf/x86/intel: Fix crash in icl_update_topdown_event()
In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel: Fix crash in icl_update_topdown_event() The perf_fuzzer found a hard-lockup crash on a RaptorLake machine: Oops: general protection fault, maybe for address 0xffff89aeceab400: 0000 CPU: 23 UID: 0 PID: 0 Comm: swapper/23 Tainted: [W]=WARN Hardware name: Dell Inc. Precision 9660/0VJ762 RIP: 0010:native_read_pmc+0x7/0x40 Code: cc e8 8d a9 01 00 48 89 03 5b cd cc cc cc cc 0f 1f ... RSP: 000:fffb03100273de8 EFLAGS: 00010046 .... Call Trace: icl_update_topdown_event+0x165/0x190 ? ktime_get+0x38/0xd0 intel_pmu_read_event+0xf9/0x210 __perf_event_read+0xf9/0x210 CPUs 16-23 are E-core CPUs that don't support the perf metrics feature. The icl_update_topdown_event() should not be invoked on these CPUs. It's a regression of commit: f9bdf1f95339 ("perf/x86/intel: Avoid disable PMU if !cpuc->enabled in sample read") The bug introduced by that commit is that the is_topdown_event() function is mistakenly used to replace the is_topdown_count() call to check if the topdown functions for the perf metrics feature should be invoked. Fix it.
