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 all domains to execute in fips_mode, you must turn
78 on the fips_mode boolean. Enabled by default.
79 setsebool -P fips_mode 1
81 If you want to control the ability to mmap a low area of the address
85 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
86 the mmap_low_allowed boolean. Disabled by default.
87 setsebool -P mmap_low_allowed 1
89 If you want to disable kernel module loading, you must turn on the
93 secure_mode_insmod boolean. Enabled by default.
94 setsebool -P secure_mode_insmod 1
96 If you want to allow unconfined executables to make their heap memory
100 executable. Doing this is a really bad idea. Probably indicates a
101 badly coded executable, but could indicate an attack. This executable
102 should be reported in bugzilla, you must turn on the selin‐
103 uxuser_execheap boolean. Disabled by default.
104 setsebool -P selinuxuser_execheap 1
106 If you want to allow unconfined executables to make their stack exe‐
110 cutable. This should never, ever be necessary. Probably indicates a
111 badly coded executable, but could indicate an attack. This executable
112 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
113 stack boolean. Enabled by default.
114 setsebool -P selinuxuser_execstack 1
116
120 The SELinux process type boinc_project_t can manage files labeled with
121 the following file types. The paths listed are the default paths for
122 these file types. Note the processes UID still need to have DAC per‐
123 missions.
124 file_type
126 all files on the system
128
131 SELinux requires files to have an extended attribute to define the file
132 type.
133 You can see the context of a file using the -Z option to ls
135 Policy governs the access confined processes have to these files.
137 SELinux boinc_project policy is very flexible allowing users to setup
138 their boinc_project processes in as secure a method as possible.
139 STANDARD FILE CONTEXT
141 SELinux defines the file context types for the boinc_project, if you
143 wanted to store files with these types in a diffent paths, you need to
144 execute the semanage command to sepecify alternate labeling and then
145 use restorecon to put the labels on disk.
146 semanage fcontext -a -t boinc_project_var_lib_t
148 '/srv/myboinc_project_content(/.*)?'
149 restorecon -R -v /srv/myboinc_project_content
150 Note: SELinux often uses regular expressions to specify labels that
152 match multiple files.
153 The following file types are defined for boinc_project:
155 boinc_project_tmp_t
159 - Set files with the boinc_project_tmp_t type, if you want to store
161 boinc project temporary files in the /tmp directories.
162 boinc_project_var_lib_t
166 - Set files with the boinc_project_var_lib_t type, if you want to store
168 the boinc project files under the /var/lib directory.
169 Paths:
172 /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?
173 Note: File context can be temporarily modified with the chcon command.
176 If you want to permanently change the file context you need to use the
177 semanage fcontext command. This will modify the SELinux labeling data‐
178 base. You will need to use restorecon to apply the labels.
179
182 semanage fcontext can also be used to manipulate default file context
183 mappings.
184 semanage permissive can also be used to manipulate whether or not a
186 process type is permissive.
187 semanage module can also be used to enable/disable/install/remove pol‐
189 icy modules.
190 semanage boolean can also be used to manipulate the booleans
192 system-config-selinux is a GUI tool available to customize SELinux pol‐
195 icy settings.
