6 checkpc_selinux - Security Enhanced Linux Policy for the checkpc pro‐
7 cesses
8
10 Security-Enhanced Linux secures the checkpc processes via flexible
11 mandatory access control.
12 The checkpc processes execute with the checkpc_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep checkpc_t
20
24 The checkpc_t SELinux type can be entered via the checkpc_exec_t file
25 type.
26 The default entrypoint paths for the checkpc_t domain are the follow‐
28 ing:
29 /usr/sbin/checkpc
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 checkpc policy is very flexible allowing users to setup their checkpc
40 processes in as secure a method as possible.
41 The following process types are defined for checkpc:
43 checkpc_t
45 Note: semanage permissive -a checkpc_t can be used to make the process
47 type checkpc_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. checkpc
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run checkpc with the tightest access possi‐
56 ble.
57 If you want to allow all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63 setsebool -P allow_daemons_use_tty 1
65 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70 setsebool -P allow_domain_fd_use 1
72 If you want to allow sysadm to debug or ptrace all processes, you must
76 turn on the allow_ptrace boolean. Disabled by default.
77 setsebool -P allow_ptrace 1
79 If you want to allow system to run with NIS, you must turn on the
83 allow_ypbind boolean. Disabled by default.
84 setsebool -P allow_ypbind 1
86 If you want to allow all domains to have the kernel load modules, you
90 must turn on the domain_kernel_load_modules boolean. Disabled by
91 default.
92 setsebool -P domain_kernel_load_modules 1
94 If you want to allow all domains to execute in fips_mode, you must turn
98 on the fips_mode boolean. Enabled by default.
99 setsebool -P fips_mode 1
101 If you want to enable reading of urandom for all domains, you must turn
105 on the global_ssp boolean. Disabled by default.
106 setsebool -P global_ssp 1

112 The SELinux process type checkpc_t can manage files labeled with the
113 following file types. The paths listed are the default paths for these
114 file types. Note the processes UID still need to have DAC permissions.
115 checkpc_log_t
117 initrc_tmp_t
120 mnt_t
123 /mnt(/[^/]*)
125 /mnt(/[^/]*)?
126 /rhev(/[^/]*)?
127 /media(/[^/]*)
128 /media(/[^/]*)?
129 /etc/rhgb(/.*)?
130 /media/.hal-.*
131 /net
132 /afs
133 /rhev
134 /misc
135 print_spool_t
137 /var/spool/lpd(/.*)?
139 /var/spool/cups(/.*)?
140 /var/spool/cups-pdf(/.*)?
141 tmp_t
143 /tmp
145 /usr/tmp
146 /var/tmp
147 /tmp-inst
148 /var/tmp-inst
149 /var/tmp/vi.recover

153 SELinux requires files to have an extended attribute to define the file
154 type.
155 You can see the context of a file using the -Z option to ls
157 Policy governs the access confined processes have to these files.
159 SELinux checkpc policy is very flexible allowing users to setup their
160 checkpc processes in as secure a method as possible.
161 STANDARD FILE CONTEXT
163 SELinux defines the file context types for the checkpc, if you wanted
165 to store files with these types in a diffent paths, you need to execute
166 the semanage command to sepecify alternate labeling and then use
167 restorecon to put the labels on disk.
168 semanage fcontext -a -t checkpc_log_t '/srv/mycheckpc_content(/.*)?'
170 restorecon -R -v /srv/mycheckpc_content
171 Note: SELinux often uses regular expressions to specify labels that
173 match multiple files.
174 The following file types are defined for checkpc:
176 checkpc_exec_t
180 - Set files with the checkpc_exec_t type, if you want to transition an
182 executable to the checkpc_t domain.
183 checkpc_log_t
187 - Set files with the checkpc_log_t type, if you want to treat the data
189 as checkpc log data, usually stored under the /var/log directory.
190 Note: File context can be temporarily modified with the chcon command.
194 If you want to permanently change the file context you need to use the
195 semanage fcontext command. This will modify the SELinux labeling data‐
196 base. You will need to use restorecon to apply the labels.
197
200 semanage fcontext can also be used to manipulate default file context
201 mappings.
202 semanage permissive can also be used to manipulate whether or not a
204 process type is permissive.
205 semanage module can also be used to enable/disable/install/remove pol‐
207 icy modules.
208 semanage boolean can also be used to manipulate the booleans
210 system-config-selinux is a GUI tool available to customize SELinux pol‐
213 icy settings.
