Paul, Thank you for reporting the issue. This AVC will be dontaudited in the next version of the selinux-policy package. Apart from the denial reported, do you also see any functionality issue?
Thanks, no functionality issues so far.
I saw a few more right after install, if you would like I can open separate bugs.
Listed below:

Paul, No need to create bugzillas for the setsched permission unless you see an issue with the software. With the update the denials will no longer be audited. Closing this bz as duplicate of bz#1795524, you can find additional information there if interested. *** This bug has been marked as a duplicate of bug 1795524 *** |
Description of problem: After fresh install of Fedora Server (Fedora-32-20200306.n.0 compose) SELinux is preventing ModemManager from using the setsched access on a process. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that ModemManager should be allowed setsched access on processes labeled modemmanager_t 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 'ModemManager' --raw | audit2allow -M my-ModemManager # semodule -X 300 -i my-ModemManager.pp Additional Information: Source Context system_u:system_r:modemmanager_t:s0 Target Context system_u:system_r:modemmanager_t:s0 Target Objects Unknown [ process ] Source ModemManager Source Path ModemManager Port <Unknown> Host localhost.localdomain Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.14.5-28.fc32.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name localhost.localdomain Platform Linux localhost.localdomain 5.6.0-0.rc3.git0.1.fc32.aarch64 #1 SMP Mon Feb 24 21:17:09 UTC 2020 aarch64 aarch64 Alert Count 1 First Seen 2020-03-06 10:22:16 EST Last Seen 2020-03-06 10:22:16 EST Local ID c49dbc7d-44cd-48e2-9872-fdba6a3b9225 Raw Audit Messages type=AVC msg=audit(1583508136.643:131): avc: denied { setsched } for pid=1156 comm="ModemManager" scontext=system_u:system_r:modemmanager_t:s0 tcontext=system_u:system_r:modemmanager_t:s0 tclass=process permissive=0 Hash: ModemManager,modemmanager_t,modemmanager_t,process,setsched
