Description of problem: sensord is being denied access to /proc/loadavg. I have run audit2allow and semodule countless times trying to fix this, and get no errors when I do, but the policy is not being applied. Version-Release number of selected component (if applicable): lm_sensors-sensord-3.3.4-10.fc20.x86_64 selinux-policy-3.12.1-182.fc20.noarch policycoreutils-python-2.2.5-4.fc20.x86_64 policycoreutils-2.2.5-4.fc20.x86_64 How reproducible: 100% Steps to Reproduce: 1. Install lmsensors-sensord 2. Configure sensord to read the loadaverage 3. start sensord Actual results: journal fills up with AVC denials for sensord reading /proc/loadavg Expected results: quiet journal, loadaverage readings being recorded in sensord database. Additional info: sealert for (one of) the incidents: [root@repohost ~]# sealert -l cf9056f1-ef5e-44e9-aaaa-b7d2125a43f1 SELinux is preventing /usr/sbin/sensord.#prelink#.eHFdJ5 (deleted) from getattr access on the file . ***** Plugin catchall (100. confidence) suggests ************************** If you believe that sensord.#prelink#.eHFdJ5 (deleted) should be allowed getattr access on the 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: # grep sensord /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:sensord_t:s0 Target Context system_u:object_r:proc_t:s0 Target Objects [ file ] Source sensord Source Path /usr/sbin/sensord.#prelink#.eHFdJ5 (deleted) Port <Unknown> Host repohost.localdomain.net Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.12.1-182.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name repohost.localdomain.net Platform Linux repohost.localdomain.net 3.15.10-201.fc20.x86_64 #1 SMP Wed Aug 27 21:10:06 UTC 2014 x86_64 x86_64 Alert Count 4 First Seen 2014-09-17 22:24:00 CDT Last Seen 2014-09-17 22:27:00 CDT Local ID cf9056f1-ef5e-44e9-aaaa-b7d2125a43f1 Raw Audit Messages type=AVC msg=audit(1411010820.596:34291): avc: denied { getattr } for pid=523 comm="sensord" path="/proc/loadavg" dev="proc" ino=4026532000 scontext=system_u:system_r:sensord_t:s0 tcontext=system_u:object_r:proc_t:s0 tclass=file type=SYSCALL msg=audit(1411010820.596:34291): arch=x86_64 syscall=fstat success=no exit=EACCES a0=1 a1=7fff5d2e3440 a2=7fff5d2e3440 a3=7f48392419c0 items=0 ppid=1 pid=523 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=sensord exe=2F7573722F7362696E2F73656E736F72642E237072656C696E6B232E654846644A35202864656C6574656429 subj=system_u:system_r:sensord_t:s0 key=(null) Hash: sensord,sensord_t,proc_t,file,getattr
commit 1de9e6691094b4269cb764484014746583221f70 Author: Lukas Vrabec <lvrabec> Date: Mon Sep 22 10:59:47 2014 +0200 Allow sensord read in /proc BZ(#1143799) https://github.com/selinux-policy/selinux-policy/commit/1de9e6691094b4269cb764484014746583221f70
The point is you need to have all AVC msgs from permissive mode to create a local policy. So you would need to run # semanage permissive -a sensord_t re-test # grep sensord_t /var/log/audit/audit.log |audit2allow -M mypol # semodule -i mypol.pp # semanage permissive -d sensord_t

This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. 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 '20'. 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 20 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 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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.
