This avc shows that the fail2ban script is trying to create a directory in /? This is probably not what you wanted, so SELinux blocks it. I would figure you intend fail2ban to write to a homedir, which is not setup correctly when fail2ban runs. |
Description of problem: SELinux is preventing mkdir from 'write' accesses on the directory /. ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If you want to allow daemons to dump core Then you must tell SELinux about this by enabling the 'daemons_dump_core' boolean. You can read 'None' man page for more details. Do setsebool -P daemons_dump_core 1 ***** Plugin catchall (11.6 confidence) suggests ************************** If you believe that mkdir should be allowed write access on the 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 mkdir --raw | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:fail2ban_t:s0 Target Context system_u:object_r:root_t:s0 Target Objects / [ dir ] Source mkdir Source Path mkdir Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages filesystem-3.2-35.fc23.x86_64 Policy RPM selinux-policy-3.13.1-158.12.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.4.6-301.fc23.x86_64 #1 SMP Wed Mar 30 16:43:58 UTC 2016 x86_64 x86_64 Alert Count 1 First Seen 2016-04-09 13:19:15 YEKT Last Seen 2016-04-09 13:19:15 YEKT Local ID 92150f7f-c3bb-41a0-a8bc-d52de3461075 Raw Audit Messages type=AVC msg=audit(1460189955.3:276): avc: denied { write } for pid=1148 comm="mkdir" name="/" dev="sda4" ino=2 scontext=system_u:system_r:fail2ban_t:s0 tcontext=system_u:object_r:root_t:s0 tclass=dir permissive=0 Hash: mkdir,fail2ban_t,root_t,dir,write Version-Release number of selected component: selinux-policy-3.13.1-158.12.fc23.noarch Additional info: reporter: libreport-2.6.4 hashmarkername: setroubleshoot kernel: 4.4.6-301.fc23.x86_64 type: libreport
