Subject: [PATCH 0/3] perf/x86/intel/pt: Address filtering fixes for perf/urgent
Date: Thu, 15 Sep 2016 16:29:41 +0300 [thread overview]
Message-ID: <20160915132944.10331-1-alexander.shishkin@linux.intel.com> (raw)
Hi,
Hoping that it's not too late, here are fixes for issues that Adrian
found. All three are good for -stable afaict. Two of the bugs result
in a #GP and one in a misconfigured filter.
2/3 can be moved into the PT driver as well, but I decided that others
may benefit from it at least theoretically.
Alexander Shishkin (3):
perf/x86/intel/pt: Fix an off-by-one in address filter configuration
perf/x86: Tighten up the kernel_ip() check
perf/x86/intel/pt: Do validate the size of a kernel address filter
