6 fcoemon_selinux - Security Enhanced Linux Policy for the fcoemon pro‐
7 cesses
8
10 Security-Enhanced Linux secures the fcoemon processes via flexible
11 mandatory access control.
12 The fcoemon processes execute with the fcoemon_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 fcoemon_t
20
24 The fcoemon_t SELinux type can be entered via the fcoemon_exec_t file
25 type.
26 The default entrypoint paths for the fcoemon_t domain are the follow‐
28 ing:
29 /usr/sbin/fcoemon
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 fcoemon policy is very flexible allowing users to setup their fcoemon
40 processes in as secure a method as possible.
41 The following process types are defined for fcoemon:
43 fcoemon_t
45 Note: semanage permissive -a fcoemon_t can be used to make the process
47 type fcoemon_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. fcoemon
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run fcoemon with the tightest access possi‐
56 ble.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the daemons_dump_core boolean. Disabled by default.

90 default.

93 If you want to allow any process to mmap any file on system with
97 attribute file_type, you must turn on the domain_can_mmap_files bool‐
98 ean. Enabled by default.
99 setsebool -P domain_can_mmap_files 1
101 If you want to allow all domains write to kmsg_device, while kernel is
105 executed with systemd.log_target=kmsg parameter, you must turn on the
106 domain_can_write_kmsg boolean. Disabled by default.
107 setsebool -P domain_can_write_kmsg 1
109 If you want to allow all domains to use other domains file descriptors,
113 you must turn on the domain_fd_use boolean. Enabled by default.
114 setsebool -P domain_fd_use 1
116 If you want to allow all domains to have the kernel load modules, you
120 must turn on the domain_kernel_load_modules boolean. Disabled by
121 default.
122 setsebool -P domain_kernel_load_modules 1
124 If you want to allow all domains to execute in fips_mode, you must turn
128 on the fips_mode boolean. Enabled by default.
129 setsebool -P fips_mode 1
131 If you want to enable reading of urandom for all domains, you must turn
135 on the global_ssp boolean. Disabled by default.
136 setsebool -P global_ssp 1

142 The SELinux process type fcoemon_t can manage files labeled with the
143 following file types. The paths listed are the default paths for these
144 file types. Note the processes UID still need to have DAC permissions.

192 SELinux requires files to have an extended attribute to define the file
193 type.
194 You can see the context of a file using the -Z option to ls
196 Policy governs the access confined processes have to these files.
198 SELinux fcoemon policy is very flexible allowing users to setup their
199 fcoemon processes in as secure a method as possible.
200 STANDARD FILE CONTEXT
202 SELinux defines the file context types for the fcoemon, if you wanted
204 to store files with these types in a diffent paths, you need to execute
205 the semanage command to sepecify alternate labeling and then use
206 restorecon to put the labels on disk.
207 semanage fcontext -a -t fcoemon_var_run_t '/srv/myfcoemon_con‐
209 tent(/.*)?'
210 restorecon -R -v /srv/myfcoemon_content
211 Note: SELinux often uses regular expressions to specify labels that
213 match multiple files.
214 The following file types are defined for fcoemon:
216 fcoemon_exec_t
220 - Set files with the fcoemon_exec_t type, if you want to transition an
222 executable to the fcoemon_t domain.
223 fcoemon_initrc_exec_t
227 - Set files with the fcoemon_initrc_exec_t type, if you want to transi‐
229 tion an executable to the fcoemon_initrc_t domain.
230 fcoemon_var_run_t
234 - Set files with the fcoemon_var_run_t type, if you want to store the
236 fcoemon files under the /run or /var/run directory.
237 Paths:
240 /var/run/fcm(/.*)?, /var/run/fcoemon.pid
241 Note: File context can be temporarily modified with the chcon command.
244 If you want to permanently change the file context you need to use the
245 semanage fcontext command. This will modify the SELinux labeling data‐
246 base. You will need to use restorecon to apply the labels.
247
250 semanage fcontext can also be used to manipulate default file context
251 mappings.
252 semanage permissive can also be used to manipulate whether or not a
254 process type is permissive.
255 semanage module can also be used to enable/disable/install/remove pol‐
257 icy modules.
258 semanage boolean can also be used to manipulate the booleans
260 system-config-selinux is a GUI tool available to customize SELinux pol‐
263 icy settings.
