Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: All my services in F26 with PrivateDevices=true fail because the SELinux transition from init_t to the daemon domain is blocked, rendering the PrivateDevices directive unusable. The services worked in F25, so something has changed between versions. Version-Release number of selected component (if applicable): selinux-policy-3.13.1-259.fc26.noarch systemd-233-6.fc26.x86_64 kernel-4.11.8-300.fc26.x86_64 How reproducible: Always Steps to Reproduce: 1. Run a SELinux confined daemon with PrivateDevices=true Actual results: Daemon runs with init_t Expected results: Daemon process transitions to its own domain Additional info: This is an example AVC of amavisd.service in F26: SELinux is preventing amavisd from ioctl access on the file /usr/sbin/amavisd. ***** Plugin catchall (100. confidence) suggests ************************** If cree que de manera predeterminada, amavisd debería permitir acceso ioctl sobre amavisd file. Then debería reportar esto como un error. Puede generar un módulo de política local para permitir este acceso. Do allow this access for now by executing: # ausearch -c 'amavisd' --raw | audit2allow -M my-amavisd # semodule -X 300 -i my-amavisd.pp Additional Information: Source Context system_u:system_r:init_t:s0 Target Context system_u:object_r:antivirus_exec_t:s0 Target Objects /usr/sbin/amavisd [ file ] Source amavisd Source Path amavisd Port <Unknown> Host argon Source RPM Packages Target RPM Packages amavisd-new-2.11.0-6.fc26.noarch Policy RPM selinux-policy-3.13.1-259.fc26.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name argon Platform Linux argon 4.11.8-300.fc26.x86_64 #1 SMP Thu Jun 29 20:09:48 UTC 2017 x86_64 x86_64 Alert Count 93 First Seen 2017-07-08 12:09:18 CEST Last Seen 2017-07-08 23:06:09 CEST Local ID c08e43e9-df1b-4f1b-9ede-5557463000a1 Raw Audit Messages type=AVC msg=audit(1499547969.808:321): avc: denied { ioctl } for pid=3018 comm="amavisd" path="/usr/sbin/amavisd" dev="dm-0" ino=16844128 ioctlcmd=0x5401 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:antivirus_exec_t:s0 tclass=file permissive=0 Hash: amavisd,init_t,antivirus_exec_t,file,ioctl
