Maybe duplicate of Bug 1377037, because I changed the reason/title of the bug for more clarification! Also there are complaints about files in subdirectories: SELinux is preventing nfs-server-gene from write access on the file /run/systemd/generator/nfs-server.service.d/order-with-mounts.conf. ***** Plugin restorecon (99.5 confidence) suggests ************************ If you want to fix the label. /run/systemd/generator/nfs-server.service.d/order-with-mounts.conf default label should be nfsd_unit_file_t. Then you can run restorecon. Do # /sbin/restorecon -v /run/systemd/generator/nfs-server.service.d/order-with-mounts.conf ***** Plugin catchall (1.49 confidence) suggests ************************** If you believe that nfs-server-gene should be allowed write access on the order-with-mounts.conf 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 'nfs-server-gene' --raw | audit2allow -M my-nfsservergene # semodule -X 300 -i my-nfsservergene.pp Additional Information: Source Context system_u:system_r:nfsd_t:s0 Target Context system_u:object_r:systemd_unit_file_t:s0 Target Objects /run/systemd/generator/nfs-server.service.d/order- with-mounts.conf [ file ] Source nfs-server-gene Source Path nfs-server-gene Port <Unknown> Host aschmidt.graphtek.local Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-220.fc25.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name aschmidt.graphtek.local Platform Linux aschmidt.graphtek.local 4.8.4-301.fc25.x86_64 #1 SMP Tue Oct 25 00:01:49 UTC 2016 x86_64 x86_64 Alert Count 8 First Seen 2016-10-29 13:09:52 PDT Last Seen 2016-10-31 07:43:04 PDT Local ID 7e8399f8-c435-4018-9a7d-1665b9a8134e Raw Audit Messages type=AVC msg=audit(1477924984.269:589): avc: denied { write } for pid=2424 comm="nfs-server-gene" path="/run/systemd/generator/nfs-server.service.d/order-with-mounts.conf" dev="tmpfs" ino=173613 scontext=system_u:system_r:nfsd_t:s0 tcontext=system_u:object_r:systemd_unit_file_t:s0 tclass=file permissive=1 Hash: nfs-server-gene,nfsd_t,systemd_unit_file_t,file,write ***** Plugin restorecon (99.5 confidence) suggests ************************ If you want to fix the label. /run/systemd/generator/nfs-server.service.d/order-with-mounts.conf default label should be nfsd_unit_file_t. Then you can run restorecon. Do # /sbin/restorecon -v /run/systemd/generator/nfs-server.service.d/order-with-mounts.conf So, one of the following is true: 1) NFS + SELinux + systemd SHOULD conflict out of the box unless and until an admin makes wise choices about what should be allowed, and makes a small number of local policies. 2) I have misconfigured NFS. One way or another, I've failed to grasp something essential. I /did/ suspect that setting it up was just too easy for safety. I will try to google for relevant docs. I know bug reports are no place for support requests. But if you're feeling magnanimous, "order-with-mounts.conf nfs-server-gene selinux" isn't getting me anything I can identify as an explanation for what nfs thinks it's trying to do. Any hints?

Every time DNF updates software, I hit this bug! I had a new error: SELinux is preventing nfs-server-gene from add_name access on the directory nfs-server.service.d. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that nfs-server-gene should be allowed add_name access on the nfs-server.service.d directory by default.

Next Fedora update should fix it. selinux-policy-3.13.1-222.fc25 has been submitted as an update to Fedora 25. https://bodhi.fedoraproject.org/updates/FEDORA-2016-d1908bac81 selinux-policy-3.13.1-222.fc25 has been pushed to the Fedora 25 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2016-d1908bac81 selinux-policy-3.13.1-222.fc25 has been pushed to the Fedora 25 stable repository.
