hi , every body ,I install selinux-policy-targeted in my F11,and run

now I want to change selinux context of /tmp/test,but failed.I thought current shell

sysadm_t ,but also failed.
my project team plan to develop selinux policy for our system based on
selinux-policy.src.rpm. I guess is this package have not been developed? If it has been
developed ,why I cannot change to sysadm_r: sysadm_t?

[root@localhost ~]# ls -lZ /tmp/testselinux
root root unconfined_u:object_r:user_t:user_tmp_t: s0 /tmp/testselinux
This does
security context does not makes senseto me .
[root@localhost ~]#chcon unconfined_u:object_r:mytest_t /tmp/testselinux
chcon:failed to change context of '/tmp/testselinux' to
'unconfined_u:object_r:testselinux: s0 : permission denied
This also does not
make sense.
## here mytest_t defined in myapp.pp,which has successfully loaded by "semodule -i
myapp.pp"
Can you show us the module?
[root@localhost ~]# newrole -r sysadm_r -t sysadm_t
unconfined_u:unconfined_r:unconfined_t: s0 is not valid context
[root@localhost ~]# semanage login -m -s root -r s0-s0:c0.c1023 root
after reboot, graphic terminal cannot run. audit says that system_u:system_r: xdm_t
require "read" permission for system_u:object_r:httpd_sys_content_t.
I think this may be related to seuser roots default contexts in
/etc/selinux/targeted/contexts/users/root. It seems theres is not default context defined
for xdm_t there
[root@localhost ~]# id
context= root:unconfined_r:unconfined_t: s0-s0:c0-c1023
[root@localhost ~]# newrole -r sysadm_r -t sysadm_t
failed to exec shell: permission denied

With regard to mapping root to seuser root i am not sure what you are trying to achieve. i
think the root seuser is for MLS usage. But in either way i think if you edit the defaults
contexts you should be able to make it work
As for the labeling issue: the only sensible explanation i can come up with now is that
mytest_t may not be defined a files_type.
