RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2015:0458 0 normal SHIPPED_LIVE selinux-policy bug fix and enhancement update 2015-03-05 15:17:00 UTC

Description Milos Malik 2014-10-15 20:27:07 UTC 
Description of problem:
 * tomcat unit file executes a wrapper instead of the server and the wrapper is labeled bin_t

Version-Release number of selected component (if applicable):
selinux-policy-targeted-3.13.1-4.el7.noarch
selinux-policy-3.13.1-4.el7.noarch
tomcat-7.0.54-1.el7.noarch

How reproducible:
always

Steps to Reproduce:
# ps -efZ | grep tomcat
unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 root 19076 12359  0 22:25 pts/0 00:00:00 grep --color=auto tomcat
# service tomcat start
Redirecting to /bin/systemctl start  tomcat.service
# ps -efZ | grep tomcat
system_u:system_r:unconfined_service_t:s0 tomcat 19170 1 80 22:25 ?    00:00:01 java -classpath /usr/share/tomcat/bin/bootstrap.jar:/usr/share/tomcat/bin/tomcat-juli.jar:/usr/share/java/commons-daemon.jar -Dcatalina.base=/usr/share/tomcat -Dcatalina.home=/usr/share/tomcat -Djava.endorsed.dirs= -Djava.io.tmpdir=/var/cache/tomcat/temp -Djava.util.logging.config.file=/usr/share/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager org.apache.catalina.startup.Bootstrap start
unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 root 19207 12359  0 22:25 pts/0 00:00:00 grep --color=auto tomcat
#

Actual results:
 * the service runs as unconfined_service_t

Expected results:
 * the service runs as tomcat_t again
Comment 1 Miroslav Grepl 2014-10-16 13:36:08 UTC 
Does it work at all if you label the wrapper correctly?
