Looks like an apps is leaking. Do you want what you were doing when this happened. Probably this relates with vmware. Looks like whoever opens the file /run/vmware-active-nics is leaking the file descriptor to ifconfig. Running restorecon on the /run should fix the label but the problem is the vmware instance is probably running with the wrong label. ps -eZ | grep initrc_t @Comment1: Yes I wanted to install and configure the vmware tools by the pl-file as instructed by them. I initiated the process at the command-line by hand. I've not succeeded in installing the whole thing completely. As far as I have googled that might partially(?) be the fault of that vmware-script. (may not be related to this issue) I'm not a pro, if I can/should provide specific info please instruct on how to obtain them. Just run in terminal # ps -eZ | grep initrc_t That results in the following output: system_u:system_r:initrc_t:s0 1111 ? 00:00:00 lldpad system_u:system_r:initrc_t:s0 1185 ? 00:00:00 tpvmlp Looks like it is tpvmlp, which has shown itself to leak in the past. I would just dontaudit this # grep init_var_run_t /var/log/audit/audit.log | audit2alow -D -M myifconfig # semodule -i myifconfig.pp |
SELinux is preventing /sbin/ifconfig from 'read' accesses on the file /run/vmware-active-nics. ***** Plugin restorecon (99.5 confidence) suggests ************************* If you want to fix the label. /run/vmware-active-nics default label should be vmware_host_pid_t. Then you can run restorecon. Do # /sbin/restorecon -v /run/vmware-active-nics ***** Plugin catchall (1.49 confidence) suggests *************************** If you believe that ifconfig should be allowed read access on the vmware-active-nics 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 ifconfig /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:ifconfig_t:s0 Target Context system_u:object_r:init_var_run_t:s0 Target Objects /run/vmware-active-nics [ file ] Source ifconfig Source Path /sbin/ifconfig Port <Unbekannt> Host (removed) Source RPM Packages net-tools-1.60-117.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.16-38.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.40.4-5.fc15.i686 #1 SMP Tue Aug 30 14:54:41 UTC 2011 i686 i686 Alert Count 6 First Seen Mi 07 Sep 2011 21:01:12 CEST Last Seen Mi 07 Sep 2011 21:05:43 CEST Local ID fdf6d4be-77de-4fe8-9a1e-89c9b4043930 Raw Audit Messages type=AVC msg=audit(1315422343.350:113): avc: denied { read } for pid=23249 comm="ifconfig" path="/run/vmware-active-nics" dev=tmpfs ino=43976 scontext=system_u:system_r:ifconfig_t:s0 tcontext=system_u:object_r:init_var_run_t:s0 tclass=file type=SYSCALL msg=audit(1315422343.350:113): arch=i386 syscall=execve success=yes exit=0 a0=9198fb8 a1=9198fa8 a2=91981e0 a3=9198fa8 items=0 ppid=23015 pid=23249 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=ifconfig exe=/sbin/ifconfig subj=system_u:system_r:ifconfig_t:s0 key=(null) Hash: ifconfig,ifconfig_t,init_var_run_t,file,read audit2allow #============= ifconfig_t ============== allow ifconfig_t init_var_run_t:file read; audit2allow -R #============= ifconfig_t ============== allow ifconfig_t init_var_run_t:file read;
