Description of problem: I tried to change directory XFCE uses to find background images. Directory in question appears to be my home directory, which is not fuse mounted. I have some sshfs directories mounted inside my home directory but I was not accessing them when this error occured. SELinux is preventing lightdm from 'write' accesses on the directory huginn. ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If you want to allow use to fusefs home dirs Then you must tell SELinux about this by enabling the 'use_fusefs_home_dirs' boolean. You can read 'None' man page for more details. Do setsebool -P use_fusefs_home_dirs 1 ***** Plugin catchall (11.6 confidence) suggests ************************** If you believe that lightdm should be allowed write access on the huginn directory 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 'lightdm' --raw | audit2allow -M my-lightdm # semodule -X 300 -i my-lightdm.pp Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:object_r:fusefs_t:s0 Target Objects huginn [ dir ] Source lightdm Source Path lightdm Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-191.17.fc24.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.7.4-200.fc24.x86_64 #1 SMP Thu Sep 15 18:42:09 UTC 2016 x86_64 x86_64 Alert Count 5 First Seen 2016-09-27 17:31:39 EEST Last Seen 2016-09-28 09:38:14 EEST Local ID 62579515-60e3-42fa-9bd0-4f461ffec25f Raw Audit Messages type=AVC msg=audit(1475044694.817:218): avc: denied { write } for pid=1704 comm="lightdm" name="huginn" dev="dm-3" ino=5242881 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:fusefs_t:s0 tclass=dir permissive=0 Hash: lightdm,xdm_t,fusefs_t,dir,write Version-Release number of selected component: selinux-policy-3.13.1-191.17.fc24.noarch Additional info: reporter: libreport-2.7.2 hashmarkername: setroubleshoot kernel: 4.7.4-200.fc24.x86_64 type: libreport
I am getting this denial even before mounting any fuse file systems in my home directory.
Kakoskin, FIX is included in your report: ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If you want to allow use to fusefs home dirs Then you must tell SELinux about this by enabling the 'use_fusefs_home_dirs' boolean.

I apologise for the mess my mistake has caused. Issue was caused by mislabeling entire home directory to system_u:object_r:fusefs_t by mistyped command "cp -a .* ~/". Is there any reason to allow users to set the context of any file to system_u:object_r:fusefs_t outside of actual fuse mounts?
