6 boinc_project_selinux - Security Enhanced Linux Policy for the
7 boinc_project processes
8
10 Security-Enhanced Linux secures the boinc_project processes via flexi‐
11 ble mandatory access control.
12 The boinc_project processes execute with the boinc_project_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep boinc_project_t
20
24 The boinc_project_t SELinux type can be entered via the
25 boinc_project_var_lib_t file type.
26 The default entrypoint paths for the boinc_project_t domain are the
28 following:
29 /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?
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 boinc_project policy is very flexible allowing users to setup their
40 boinc_project processes in as secure a method as possible.
41 The following process types are defined for boinc_project:
43 boinc_project_t
45 Note: semanage permissive -a boinc_project_t can be used to make the
47 process type boinc_project_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 boinc_project policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run boinc_project with the
56 tightest access possible.
57 If you want to deny user domains applications to map a memory region as
61 both executable and writable, this is dangerous and the executable
62 should be reported in bugzilla, you must turn on the deny_execmem bool‐
63 ean. Enabled by default.
64 setsebool -P deny_execmem 1
66 If you want to deny any process from ptracing or debugging any other
70 processes, you must turn on the deny_ptrace boolean. Enabled by
71 default.
72 setsebool -P deny_ptrace 1
74 If you want to allow any process to mmap any file on system with
78 attribute file_type, you must turn on the domain_can_mmap_files bool‐
79 ean. Enabled by default.
80 setsebool -P domain_can_mmap_files 1
82 If you want to allow all domains write to kmsg_device, while kernel is
86 executed with systemd.log_target=kmsg parameter, you must turn on the
87 domain_can_write_kmsg boolean. Disabled by default.
88 setsebool -P domain_can_write_kmsg 1
90 If you want to allow all domains to use other domains file descriptors,
94 you must turn on the domain_fd_use boolean. Enabled by default.
95 setsebool -P domain_fd_use 1
97 If you want to allow all domains to have the kernel load modules, you
101 must turn on the domain_kernel_load_modules boolean. Disabled by
102 default.
103 setsebool -P domain_kernel_load_modules 1
105 If you want to allow all domains to execute in fips_mode, you must turn
109 on the fips_mode boolean. Enabled by default.
110 setsebool -P fips_mode 1
112 If you want to enable reading of urandom for all domains, you must turn
116 on the global_ssp boolean. Disabled by default.
117 setsebool -P global_ssp 1
119 If you want to control the ability to mmap a low area of the address
123 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
124 the mmap_low_allowed boolean. Disabled by default.
125 setsebool -P mmap_low_allowed 1
127 If you want to disable kernel module loading, you must turn on the
131 secure_mode_insmod boolean. Enabled by default.
132 setsebool -P secure_mode_insmod 1
134 If you want to boolean to determine whether the system permits loading
138 policy, setting enforcing mode, and changing boolean values. Set this
139 to true and you have to reboot to set it back, you must turn on the
140 secure_mode_policyload boolean. Enabled by default.
141 setsebool -P secure_mode_policyload 1
143 If you want to allow unconfined executables to make their heap memory
147 executable. Doing this is a really bad idea. Probably indicates a
148 badly coded executable, but could indicate an attack. This executable
149 should be reported in bugzilla, you must turn on the selin‐
150 uxuser_execheap boolean. Disabled by default.
151 setsebool -P selinuxuser_execheap 1
153 If you want to allow all unconfined executables to use libraries
157 requiring text relocation that are not labeled textrel_shlib_t, you
158 must turn on the selinuxuser_execmod boolean. Enabled by default.
159 setsebool -P selinuxuser_execmod 1
161 If you want to allow unconfined executables to make their stack exe‐
165 cutable. This should never, ever be necessary. Probably indicates a
166 badly coded executable, but could indicate an attack. This executable
167 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
168 stack boolean. Enabled by default.
169 setsebool -P selinuxuser_execstack 1
171 If you want to support X userspace object manager, you must turn on the
175 xserver_object_manager boolean. Enabled by default.
176 setsebool -P xserver_object_manager 1
178
182 The SELinux process type boinc_project_t can manage files labeled with
183 the following file types. The paths listed are the default paths for
184 these file types. Note the processes UID still need to have DAC per‐
185 missions.
186 file_type
188 all files on the system
190
193 SELinux requires files to have an extended attribute to define the file
194 type.
195 You can see the context of a file using the -Z option to ls
197 Policy governs the access confined processes have to these files.
199 SELinux boinc_project policy is very flexible allowing users to setup
200 their boinc_project processes in as secure a method as possible.
201 STANDARD FILE CONTEXT
203 SELinux defines the file context types for the boinc_project, if you
205 wanted to store files with these types in a diffent paths, you need to
206 execute the semanage command to sepecify alternate labeling and then
207 use restorecon to put the labels on disk.
208 semanage fcontext -a -t boinc_project_var_lib_t
210 '/srv/myboinc_project_content(/.*)?'
211 restorecon -R -v /srv/myboinc_project_content
212 Note: SELinux often uses regular expressions to specify labels that
214 match multiple files.
215 The following file types are defined for boinc_project:
217 boinc_project_tmp_t
221 - Set files with the boinc_project_tmp_t type, if you want to store
223 boinc project temporary files in the /tmp directories.
224 boinc_project_var_lib_t
228 - Set files with the boinc_project_var_lib_t type, if you want to store
230 the boinc project files under the /var/lib directory.
231 Paths:
234 /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?
235 Note: File context can be temporarily modified with the chcon command.
238 If you want to permanently change the file context you need to use the
239 semanage fcontext command. This will modify the SELinux labeling data‐
240 base. You will need to use restorecon to apply the labels.
241
244 semanage fcontext can also be used to manipulate default file context
245 mappings.
246 semanage permissive can also be used to manipulate whether or not a
248 process type is permissive.
249 semanage module can also be used to enable/disable/install/remove pol‐
251 icy modules.
252 semanage boolean can also be used to manipulate the booleans
254 system-config-selinux is a GUI tool available to customize SELinux pol‐
257 icy settings.
