Do you know what you were doing when this happened? Looks like aleak. (In reply to comment #1) > Do you know what you were doing when this happened? i'm not sure, but it happened not long after i updated to the "kernel-2.6.40" and installed a "H3C" client. then it happened when i run the client.

So h3c is probably leaking an open file descriptor to proc_net_t. You can safely load a policy to ignore this AVC # grep consoletype /var/log/audit/audit.log | audit2allow -D -M myconsoletype # semodule -I myconsoletype.pp Should fix the problem.

Thank you now, the problem fixed thank you all again for the help, and i think something more must be done before i report something next time. |
SELinux is preventing /sbin/consoletype from 'read' accesses on the file /proc/<pid>/net/dev. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that consoletype should be allowed read access on the dev 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 consoletype /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:consoletype_t:s0 Target Context system_u:object_r:proc_net_t:s0 Target Objects /proc/<pid>/net/dev [ file ] Source consoletype Source Path /sbin/consoletype Port <未知> Host (removed) Source RPM Packages initscripts-9.30-2.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.16-37.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.40-4.fc15.i686.PAE #1 SMP Fri Jul 29 18:47:58 UTC 2011 i686 i686 Alert Count 2 First Seen 2011年08月07日 星期日 16时32分40秒 Last Seen 2011年08月07日 星期日 16时32分41秒 Local ID 8fea2b19-8e85-47ca-955f-963b04296a4f Raw Audit Messages type=AVC msg=audit(1312705961.240:56): avc: denied { read } for pid=2307 comm="consoletype" path="/proc/1098/net/dev" dev=proc ino=4026531973 scontext=system_u:system_r:consoletype_t:s0 tcontext=system_u:object_r:proc_net_t:s0 tclass=file type=SYSCALL msg=audit(1312705961.240:56): arch=i386 syscall=execve success=yes exit=0 a0=99b0100 a1=99b5418 a2=99b1a38 a3=99b5418 items=0 ppid=2306 pid=2307 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=consoletype exe=/sbin/consoletype subj=system_u:system_r:consoletype_t:s0 key=(null) Hash: consoletype,consoletype_t,proc_net_t,file,read audit2allow #============= consoletype_t ============== allow consoletype_t proc_net_t:file read; audit2allow -R #============= consoletype_t ============== allow consoletype_t proc_net_t:file read;
