What were you trying to do in the container. Seems to be something that should be blocked? Allowing a container to modify this is probably required to run a privileged container or at least disable SELinux. --privileged or --security-opt label=disabled If you believe a non privileged container should be allowed to modify the ptrace_scope, then please reopen the container. Do you know if ptrace_scope is namespaced? The issues is present with current Fedora hosts and fedora images when upgrading elfutils-default-yama-scope, bug 1602914. |
Description of problem: SELinux is preventing systemd-sysctl from 'write' accesses on the file ptrace_scope. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that systemd-sysctl should be allowed write access on the ptrace_scope file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'systemd-sysctl' --raw | audit2allow -M my-systemdsysctl # semodule -X 300 -i my-systemdsysctl.pp Additional Information: Source Context system_u:system_r:container_t:s0:c248,c817 Target Context system_u:object_r:sysctl_kernel_t:s0 Target Objects ptrace_scope [ file ] Source systemd-sysctl Source Path systemd-sysctl Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-225.11.fc25.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.9.14-200.fc25.x86_64 #1 SMP Mon Mar 13 19:26:40 UTC 2017 x86_64 x86_64 Alert Count 1 First Seen 2017-03-24 22:53:43 PDT Last Seen 2017-03-24 22:53:43 PDT Local ID 2818407c-c1fe-4b4d-8c6b-d61d649dbc78 Raw Audit Messages type=AVC msg=audit(1490421223.448:1164): avc: denied { write } for pid=20081 comm="systemd-sysctl" name="ptrace_scope" dev="proc" ino=3972199 scontext=system_u:system_r:container_t:s0:c248,c817 tcontext=system_u:object_r:sysctl_kernel_t:s0 tclass=file permissive=0 Hash: systemd-sysctl,container_t,sysctl_kernel_t,file,write Version-Release number of selected component: selinux-policy-3.13.1-225.11.fc25.noarch Additional info: reporter: libreport-2.8.0 hashmarkername: setroubleshoot kernel: 4.9.14-200.fc25.x86_64 type: libreport
