Description of problem: After updating the selinux-policy package to version 3.13.1-166.el7.noarch, tomcat service does not start any longer due to an AVC denial: avc: denied { setsched } for pid=... comm="java" scontext=system_u:system_r:tomcat_t:s0 tcontext=system_u:system_r:tomcat_t:s0 tclass=process Version-Release number of selected component (if applicable): tomcat-7.0.76-2.el7.noarch java-1.8.0-ibm-1.8.0.4.10-1jpp.3.el7.x86_64 selinux-policy-3.13.1-166.el7_4.4.noarch How reproducible: Always Steps to Reproduce: 1. Update the selinux-package 2. Start tomcat service Actual results: service did not start, traces with classpath values Expected results: service started Additional info: Downgrading selinux-policy to version 3.13.1-102.el7_3.16 has been confirmed as a workaround. The tomcat_t domain used to be an unconfined domain in RHEL 7.3. In RHEL 7.4, only some permissions are allowed for the process class: # sesearch -A -s tomcat_t -t tomcat_t -c process Found 1 semantic av rules: allow tomcat_t tomcat_t : process { fork sigchld sigkill sigstop signull signal getsched getcap execmem } ;
