Description of problem: SELinux is preventing systemd from 'getattr' accesses on the file /etc/ssh/ssh_host_rsa_key. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that systemd should be allowed getattr access on the ssh_host_rsa_key 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 systemd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:init_t:s0 Target Context system_u:object_r:sshd_key_t:s0 Target Objects /etc/ssh/ssh_host_rsa_key [ file ] Source systemd Source Path systemd Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-166.fc24.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.4.0-1.fc24.x86_64 #1 SMP Mon Jan 11 16:48:24 UTC 2016 x86_64 x86_64 Alert Count 9 First Seen 2016-01-16 00:16:32 CET Last Seen 2016-01-16 01:02:02 CET Local ID 309aa1c1-7df2-484c-bc12-f0d5b2f09067 Raw Audit Messages type=AVC msg=audit(1452902522.632:89): avc: denied { getattr } for pid=1 comm="systemd" path="/etc/ssh/ssh_host_rsa_key" dev="dm-1" ino=1837544 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:sshd_key_t:s0 tclass=file permissive=0 Hash: systemd,init_t,sshd_key_t,file,getattr Version-Release number of selected component: selinux-policy-3.13.1-166.fc24.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.4.0-1.fc24.x86_64 type: libreport
I had a discussion with ssh maintainer Jakub Jelen, and we ended up with that getattr si enough. Here is patch which caused the issue. http://pkgs.fedoraproject.org/cgit/rpms/openssh.git/commit/?id=af94f46861844cbd6ba4162115039bebcc8f78ba I'm going to allow this.
