[Test case] Run grep with systemd-run -t --property MemoryDenyWriteExecute=yes /bin/grep crashkernel /proc/cmdline [Regression potential] The fix is a simple rebuild, so should have minimal potential for regression. ------------------------- # systemd-run -t --property MemoryDenyWriteExecute=yes /bin/grep crashkernel /proc/cmdline Running as unit: run-u54.service Press ^] three times within 1s to disconnect TTY. /bin/grep: error while loading shared libraries: cannot restore segment prot after reloc: Operation not permitted # Under ppc64el, grep can't be used under udev, because it restricts mapping to be Write+Execute, with MemoryDenyWriteExecute=yes. A rebuild of grep under bionic fixes the issue.
