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 control the ability to mmap a low area of the address
70 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
71 the mmap_low_allowed boolean. Disabled by default.
72 setsebool -P mmap_low_allowed 1
74 If you want to disable kernel module loading, you must turn on the se‐
78 cure_mode_insmod boolean. Enabled by default.
79 setsebool -P secure_mode_insmod 1
81 If you want to allow unconfined executables to make their heap memory
85 executable. Doing this is a really bad idea. Probably indicates a
86 badly coded executable, but could indicate an attack. This executable
87 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
88 echeap boolean. Disabled by default.
89 setsebool -P selinuxuser_execheap 1

95 The SELinux process type boinc_project_t can manage files labeled with
96 the following file types. The paths listed are the default paths for
97 these file types. Note the processes UID still need to have DAC per‐
98 missions.
99 file_type
101 all files on the system
103
106 SELinux requires files to have an extended attribute to define the file
107 type.
108 You can see the context of a file using the -Z option to ls
110 Policy governs the access confined processes have to these files.
112 SELinux boinc_project policy is very flexible allowing users to setup
113 their boinc_project processes in as secure a method as possible.
114 STANDARD FILE CONTEXT
116 SELinux defines the file context types for the boinc_project, if you
118 wanted to store files with these types in a diffent paths, you need to
119 execute the semanage command to specify alternate labeling and then use
120 restorecon to put the labels on disk.
121 semanage fcontext -a -t boinc_project_var_lib_t '/srv/my‐
123 boinc_project_content(/.*)?'
124 restorecon -R -v /srv/myboinc_project_content
125 Note: SELinux often uses regular expressions to specify labels that
127 match multiple files.
128 The following file types are defined for boinc_project:
130 boinc_project_tmp_t
134 - Set files with the boinc_project_tmp_t type, if you want to store
136 boinc project temporary files in the /tmp directories.
137 boinc_project_var_lib_t
141 - Set files with the boinc_project_var_lib_t type, if you want to store
143 the boinc project files under the /var/lib directory.
144 Paths:
147 /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?
148 Note: File context can be temporarily modified with the chcon command.
151 If you want to permanently change the file context you need to use the
152 semanage fcontext command. This will modify the SELinux labeling data‐
153 base. You will need to use restorecon to apply the labels.
154
157 semanage fcontext can also be used to manipulate default file context
158 mappings.
159 semanage permissive can also be used to manipulate whether or not a
161 process type is permissive.
162 semanage module can also be used to enable/disable/install/remove pol‐
164 icy modules.
165 semanage boolean can also be used to manipulate the booleans
167 system-config-selinux is a GUI tool available to customize SELinux pol‐
170 icy settings.
