6 publicfile_selinux - Security Enhanced Linux Policy for the publicfile
7 processes
8
10 Security-Enhanced Linux secures the publicfile processes via flexible
11 mandatory access control.
12 The publicfile processes execute with the publicfile_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep publicfile_t
20
24 The publicfile_t SELinux type can be entered via the publicfile_exec_t
25 file type.
26 The default entrypoint paths for the publicfile_t domain are the fol‐
28 lowing:
29 /usr/bin/ftpd, /usr/bin/httpd
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 publicfile policy is very flexible allowing users to setup their pub‐
40 licfile processes in as secure a method as possible.
41 The following process types are defined for publicfile:
43 publicfile_t
45 Note: semanage permissive -a publicfile_t can be used to make the
47 process type publicfile_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. public‐
54 file policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run publicfile with the tightest
56 access possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.
62 setsebool -P allow_daemons_dump_core 1
64 If you want to allow all daemons to use tcp wrappers, you must turn on
68 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
69 setsebool -P allow_daemons_use_tcp_wrapper 1
71 If you want to allow all daemons the ability to read/write terminals,
75 you must turn on the allow_daemons_use_tty boolean. Disabled by
76 default.
77 setsebool -P allow_daemons_use_tty 1
79 If you want to allow all domains to use other domains file descriptors,
83 you must turn on the allow_domain_fd_use boolean. Enabled by default.
84 setsebool -P allow_domain_fd_use 1
86 If you want to allow sysadm to debug or ptrace all processes, you must
90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1
93 If you want to enable cluster mode for daemons, you must turn on the
97 daemons_enable_cluster_mode boolean. Disabled by default.
98 setsebool -P daemons_enable_cluster_mode 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1

133 The SELinux process type publicfile_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

196 SELinux requires files to have an extended attribute to define the file
197 type.
198 You can see the context of a file using the -Z option to ls
200 Policy governs the access confined processes have to these files.
202 SELinux publicfile policy is very flexible allowing users to setup
203 their publicfile processes in as secure a method as possible.
204 STANDARD FILE CONTEXT
206 SELinux defines the file context types for the publicfile, if you
208 wanted to store files with these types in a diffent paths, you need to
209 execute the semanage command to sepecify alternate labeling and then
210 use restorecon to put the labels on disk.
211 semanage fcontext -a -t publicfile_content_t '/srv/mypublicfile_con‐
213 tent(/.*)?'
214 restorecon -R -v /srv/mypublicfile_content
215 Note: SELinux often uses regular expressions to specify labels that
217 match multiple files.
218 The following file types are defined for publicfile:
220 publicfile_content_t
224 - Set files with the publicfile_content_t type, if you want to treat
226 the files as publicfile content.
227 publicfile_exec_t
231 - Set files with the publicfile_exec_t type, if you want to transition
233 an executable to the publicfile_t domain.
234 Paths:
237 /usr/bin/ftpd, /usr/bin/httpd
238 Note: File context can be temporarily modified with the chcon command.
241 If you want to permanently change the file context you need to use the
242 semanage fcontext command. This will modify the SELinux labeling data‐
243 base. You will need to use restorecon to apply the labels.
244
247 semanage fcontext can also be used to manipulate default file context
248 mappings.
249 semanage permissive can also be used to manipulate whether or not a
251 process type is permissive.
252 semanage module can also be used to enable/disable/install/remove pol‐
254 icy modules.
255 semanage boolean can also be used to manipulate the booleans
257 system-config-selinux is a GUI tool available to customize SELinux pol‐
260 icy settings.
