From 34fe3cfda826e221d15610aa07364384bf8adb94 Mon Sep 17 00:00:00 2001 From: Alexander Kapshuk Date: Thu, 31 May 2018 22:22:46 +0300 Subject: ver_linux: Process input coming from procmaps that matches libc only Currently, input coming from /proc/self/maps is split into fields without checking whether or not it matches libc.so. This is not efficient. All text processing should only be performed on lines of input that match libc.so.
