Description of problem: run perf top as sysadm_r SELinux is preventing /usr/bin/perf from 'read' accesses on the file . ***** Plugin catchall (100. confidence) suggests ************************** If you believe that perf should be allowed read access on the 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 perf /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context staff_u:sysadm_r:sysadm_t:s0-s0:c0.c1023 Target Context system_u:object_r:proc_kcore_t:s0 Target Objects [ file ] Source perf Source Path /usr/bin/perf Port <Unknown> Host (removed) Source RPM Packages perf-3.14.4-200.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-163.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.14.4-200.fc20.x86_64 #1 SMP Thu May 22 17:12:34 CST 2014 x86_64 x86_64 Alert Count 1 First Seen 2014-05-23 10:10:13 CST Last Seen 2014-05-23 10:10:13 CST Local ID 6077a442-98d8-495e-92e9-9799d870e8e9 Raw Audit Messages type=AVC msg=audit(1400805613.895:472): avc: denied { read } for pid=7935 comm="perf" name="kcore" dev="proc" ino=4026532004 scontext=staff_u:sysadm_r:sysadm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:proc_kcore_t:s0 tclass=file type=SYSCALL msg=audit(1400805613.895:472): arch=x86_64 syscall=open success=no exit=EACCES a0=7fffde1938b0 a1=0 a2=0 a3=0 items=1 ppid=7591 pid=7935 auid=1343600009 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts0 ses=2 comm=perf exe=/usr/bin/perf subj=staff_u:sysadm_r:sysadm_t:s0-s0:c0.c1023 key=(null) type=CWD msg=audit(1400805613.895:472): cwd=/root type=PATH msg=audit(1400805613.895:472): item=0 name=/proc/kcore inode=4026532004 dev=00:02 mode=0100400 ouid=0 ogid=0 rdev=00:00 obj=system_u:object_r:proc_kcore_t:s0 nametype=NORMAL Hash: perf,sysadm_t,proc_kcore_t,file,read Additional info: reporter: libreport-2.2.2 hashmarkername: setroubleshoot kernel: 3.14.4-200.fc20.x86_64 type: libreport
