SELinux is preventing /usr/bin/ps from 'getattr' accesses on the directory /proc/<pid>.
Last modified: 2013-10-24 13:51:51 EDT
Description of problem: SELinux is preventing /usr/bin/ps from 'getattr' accesses on the directory /proc/<pid>. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that ps should be allowed getattr access on the <pid> 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: # grep ps /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:rabbitmq_beam_t:s0 Target Context system_u:system_r:rabbitmq_epmd_t:s0 Target Objects /proc/<pid> [ dir ] Source ps Source Path /usr/bin/ps Port <Unknown> Host (removed) Source RPM Packages procps-ng-3.3.8-8.fc19.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-59.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 3.9.9-301.fc19.x86_64 #1 SMP Thu Jul 4 15:10:36 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-07-08 11:42:25 CEST Last Seen 2013-07-08 11:42:25 CEST Local ID 7d21963a-49c2-41f7-9ed8-cca12a8761f7 Raw Audit Messages type=AVC msg=audit(1373276545.908:474): avc: denied { getattr } for pid=1179 comm="ps" path="/proc/557" dev="proc" ino=19577 scontext=system_u:system_r:rabbitmq_beam_t:s0 tcontext=system_u:system_r:rabbitmq_epmd_t:s0 tclass=dir type=SYSCALL msg=audit(1373276545.908:474): arch=x86_64 syscall=stat success=yes exit=0 a0=1bcb5b0 a1=3e8f612a80 a2=3e8f612a80 a3=0 items=0 ppid=378 pid=1179 auid=4294967295 uid=990 gid=988 euid=990 suid=990 fsuid=990 egid=988 sgid=988 fsgid=988 ses=4294967295 tty=(none) comm=ps exe=/usr/bin/ps subj=system_u:system_r:rabbitmq_beam_t:s0 key=(null) Hash: ps,rabbitmq_beam_t,rabbitmq_epmd_t,dir,getattr Additional info: reporter: libreport-2.1.5 hashmarkername: setroubleshoot kernel: 3.9.9-301.fc19.x86_64 type: libreport

I'm still seeing the issue with selinux-policy-3.12.1-63.fc19: type=AVC msg=audit(1373983035.745:640): avc: denied { getattr } for pid=18732 comm="ps" path="/proc/493" dev="proc" ino=12914 scontext=system_u:system_r:rabbitmq_beam_t:s0 tcontext=system_u:system_r:initrc_t:s0 tclass=dir
What does # ps -eZ |grep initrc on your system?
It doesn't return anything.
I picked another entry from the audit log after attemping to start rabbitmq: type=SYSCALL msg=audit(1374517789.081:24532): arch=c000003e syscall=4 success=no exit=-13 a0=10405c0 a1=7fd6a7f93a80 a2=7fd6a7f93a80 a3=0 items=0 ppid=1969 pid=2018 auid=4294967295 uid=996 gid=997 euid=996 suid=996 fsuid=996 egid=997 sgid=997 fsgid=997 ses=4294967295 tty=(none) comm="ps" exe="/usr/bin/ps" subj=system_u:system_r:rabbitmq_beam_t:s0 key=(null) type=AVC msg=audit(1374517789.081:24533): avc: denied { getattr } for pid=2018 comm="ps" path="/proc/350" dev="proc" ino=10558 scontext=system_u:system_r:rabbitmq_beam_t:s0 tcontext=system_u:system_r:syslogd_t:s0 tclass=dir type=SYSCALL msg=audit(1374517789.081:24533): arch=c000003e syscall=4 success=no exit=-13 a0=10405c0 a1=7fd6a7f93a80 a2=7fd6a7f93a80 a3=0 items=0 ppid=1969 pid=2018 auid=4294967295 uid=996 gid=997 euid=996 suid=996 fsuid=996 egid=997 sgid=997 fsgid=997 ses=4294967295 tty=(none) comm="ps" exe="/usr/bin/ps" subj=system_u:system_r:rabbitmq_beam_t:s0 key=(null) ps -eZ | grep syslogd gives: system_u:system_r:syslogd_t:s0 270 ? 00:00:00 systemd-journal system_u:system_r:syslogd_t:s0 350 ? 00:00:00 rsyslogd
Ah, and the log in the previous message is with selinux-policy-3.12.1-65.fc19.
Can this bug be reopened? It's marked as closed but there's nobody in https://admin.fedoraproject.org/updates/FEDORA-2013-12762/selinux-policy-3.12.1-63.fc19 who seems to have tested it. I currently have to disable SELinux to be able to start the distro version of RabbitMQ.
What AVC are you currently seeing?
I've retested with selinux-policy-3.12.1-69.fc19 and the ps related denials are gone. It's still not starting though: there are now a bunch of name_bind denials and one name_connect denial. I've filed a new report for that: https://bugzilla.redhat.com/show_bug.cgi?id=993279 .
