Summary: radiusd cannot write to tmp

Fixed In Version: selinux-policy-2.4.6-351.el5 Doc Type: Bug Fix
Doc Text:
Due to missing rules in the SELinux policy, the radiusd daemon was unable to write to the /tmp/ directory. Consequently, when radiusd was integrated with the Kerberos network authentication system, an attempt to authenticate a user failed. This update applies a new SELinux policy module so that radiusd works correctly in the described scenario.

Comment 2 Miroslav Grepl 2014-05-13 07:46:02 UTC 
Could you re-test it with

$ cat mypol.te
policy_module(mypol,1.0)

require{
 type radiusd_t;
}

type radiusd_tmp_t;
files_tmp_file(radiusd_tmp_t)

allow radiusd_t radiusd_tmp_t:dir create_dir_perms;
allow radiusd_t radiusd_tmp_t:file create_file_perms;
files_tmp_filetrans(radiusd_t, radiuesd_tmp_t, { file dir })

optional_policy(`
    kerberos_keytab_template(radiusd, radiusd_t)
    kerberos_manage_host_rcache(radiusd_t)
')


# make -f /usr/share/selinux/devel/Makefile mypol.pp
# semodule -i mypol.pp
Comment 3 Patrik Kis 2014-05-13 09:04:00 UTC 
# cat mypol.te 
policy_module(mypol,1.0)

require{
 type radiusd_t;
}

type radiusd_tmp_t;
files_tmp_file(radiusd_tmp_t)

allow radiusd_t radiusd_tmp_t:dir create_dir_perms;
allow radiusd_t radiusd_tmp_t:file create_file_perms;
files_tmp_filetrans(radiusd_t, radiuesd_tmp_t, { file dir })

optional_policy(`
    kerberos_keytab_template(radiusd, radiusd_t)
    kerberos_manage_host_rcache(radiusd_t)
')
# make -f /usr/share/selinux/devel/Makefile mypol.pp

Comment 4 Miroslav Grepl 2014-05-13 09:13:44 UTC 
There is a typo.

-files_tmp_filetrans(radiusd_t, radiuesd_tmp_t, { file dir })
+files_tmp_filetrans(radiusd_t, radiusd_tmp_t, { file dir })
Comment 5 Patrik Kis 2014-05-13 10:01:28 UTC 
The test is working with the custom policy and no new AVC denials appeared.
