SELinux is preventing /sbin/load_policy from read, write access on the unix_stream_socket unix_stream_socket. ***** Plugin leaks (50.5 confidence) suggests ****************************** If you want to ignore load_policy trying to read write access the unix_stream_socket unix_stream_socket, because you believe it should not need this access. Then you should report this as a bug. You can generate a local policy module to dontaudit this access. Do # grep /sbin/load_policy /var/log/audit/audit.log | audit2allow -D -M mypol # semodule -i mypol.pp ***** Plugin catchall (50.5 confidence) suggests *************************** If you believe that load_policy should be allowed read write access on the unix_stream_socket unix_stream_socket 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 load_policy /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:load_policy_t:s0-s0:c0.c 1023 Target Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Objects unix_stream_socket [ unix_stream_socket ] Source load_policy Source Path /sbin/load_policy Port <Unknown> Host (removed) Source RPM Packages policycoreutils-2.0.85-28.fc14 Target RPM Packages Policy RPM selinux-policy-3.9.7-40.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 2.6.35.13-91.fc14.i686 #1 SMP Tue May 3 13:36:36 UTC 2011 i686 i686 Alert Count 1 First Seen Mon 23 May 2011 12:48:42 PM CDT Last Seen Mon 23 May 2011 12:48:42 PM CDT Local ID 6141500a-b9e4-4989-a799-219bf75ff145 Raw Audit Messages type=AVC msg=audit(1306172922.535:121): avc: denied { read write } for pid=5469 comm="load_policy" path="socket:[117938]" dev=sockfs ino=117938 scontext=unconfined_u:unconfined_r:load_policy_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=unix_stream_socket type=SYSCALL msg=audit(1306172922.535:121): arch=i386 syscall=execve success=yes exit=0 a0=9f08a20 a1=9c00360 a2=0 a3=0 items=0 ppid=5422 pid=5469 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=1 comm=load_policy exe=/sbin/load_policy subj=unconfined_u:unconfined_r:load_policy_t:s0-s0:c0.c1023 key=(null) Hash: load_policy,load_policy_t,unconfined_t,unix_stream_socket,read,write audit2allow #============= load_policy_t ============== allow load_policy_t unconfined_t:unix_stream_socket { read write }; audit2allow -R #============= load_policy_t ============== allow load_policy_t unconfined_t:unix_stream_socket { read write };
This seems to be a leaked file descriptor issue but besides that seems that this functionality is currently also missing i suspect. Could you please try: mkdir ~/mytest; cd ~/mytest; echo "policy_module(mytest, 1.0.0) gen_require(\` type unconfined_t; role unconfined_r; ') seutil_run_loadpolicy(unconfined_t, unconfined_r)" > mytest.pp make -f /usr/share/selinux/devel/Makefile mytest.pp sudo semodule -i mytest.pp ... reproduce the issue and see if this solves your problem?
Actually that seems to be a bad idea. Please remove the module i suggested above if you have installed it: semodule -r mytest Do you have any custom modules implemented with regard to running load_policy? unconfined_t probably should not transition to the load_policy_t domain i suspect. Could you provide us with some background information as to what you were trying to achieve?
I have a feeling this is happening as part of a transaction, like yum, which is leaking a file descriptor to load_policy. unconfined_t transitions to semanage_t which transitions to load_policy. It needs to do this in order to keep the labeling correct. In F15 we dontaudit these types of leaks.
We could add the seutil_run_load_policy(unconfined_t) to unconfineduser.te. It is already able to transition to many other seutils. Adding this call will also take care of the leaks and any labeling issues.
yes
