6 brctl_selinux - Security Enhanced Linux Policy for the brctl processes
7
9 Security-Enhanced Linux secures the brctl processes via flexible manda‐
10 tory access control.
11
12 The brctl processes execute with the brctl_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep brctl_t
19
20
21
23 The brctl_t SELinux type can be entered via the brctl_exec_t file type.
24
25 The default entrypoint paths for the brctl_t domain are the following:
26
27 /usr/sbin/brctl
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 brctl policy is very flexible allowing users to setup their brctl pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for brctl:
40
41 brctl_t
42
43 Note: semanage permissive -a brctl_t can be used to make the process
44 type brctl_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. brctl
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run brctl with the tightest access possible.
53
54
55
56 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
64 The SELinux process type brctl_t can manage files labeled with the fol‐
65 lowing file types. The paths listed are the default paths for these
66 file types. Note the processes UID still need to have DAC permissions.
67
68 sysfs_t
69
70 /sys(/.*)?
71
72
74 SELinux requires files to have an extended attribute to define the file
75 type.
76
77 You can see the context of a file using the -Z option to ls
78
79 Policy governs the access confined processes have to these files.
80 SELinux brctl policy is very flexible allowing users to setup their
81 brctl processes in as secure a method as possible.
82
83 The following file types are defined for brctl:
84
85
86
87 brctl_exec_t
88
89 - Set files with the brctl_exec_t type, if you want to transition an
90 executable to the brctl_t domain.
91
92
93
94 Note: File context can be temporarily modified with the chcon command.
95 If you want to permanently change the file context you need to use the
96 semanage fcontext command. This will modify the SELinux labeling data‐
97 base. You will need to use restorecon to apply the labels.
98
99
101 semanage fcontext can also be used to manipulate default file context
102 mappings.
103
104 semanage permissive can also be used to manipulate whether or not a
105 process type is permissive.
106
107 semanage module can also be used to enable/disable/install/remove pol‐
108 icy modules.
109
110 semanage boolean can also be used to manipulate the booleans
111
112
113 system-config-selinux is a GUI tool available to customize SELinux pol‐
114 icy settings.
