6 keepalived_unconfined_script_selinux - Security Enhanced Linux Policy
7 for the keepalived_unconfined_script processes
8
10 Security-Enhanced Linux secures the keepalived_unconfined_script pro‐
11 cesses via flexible mandatory access control.
12 The keepalived_unconfined_script processes execute with the
14 keepalived_unconfined_script_t SELinux type. You can check if you have
15 these processes running by executing the ps command with the -Z quali‐
16 fier.
17 For example:
19 ps -eZ | grep keepalived_unconfined_script_t
21
25 The keepalived_unconfined_script_t SELinux type can be entered via the
26 keepalived_unconfined_script_exec_t file type.
27 The default entrypoint paths for the keepalived_unconfined_script_t
29 domain are the following:
30 /usr/libexec/keepalived(/.*)?
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 keepalived_unconfined_script policy is very flexible allowing users to
41 setup their keepalived_unconfined_script processes in as secure a
42 method as possible.
43 The following process types are defined for keepalived_uncon‐
45 fined_script:
46 keepalived_unconfined_script_t
48 Note: semanage permissive -a keepalived_unconfined_script_t can be used
50 to make the process type keepalived_unconfined_script_t permissive.
51 SELinux does not deny access to permissive process types, but the AVC
52 (SELinux denials) messages are still generated.
53
56 SELinux policy is customizable based on least access required.
57 keepalived_unconfined_script policy is extremely flexible and has sev‐
58 eral booleans that allow you to manipulate the policy and run
59 keepalived_unconfined_script with the tightest access possible.
60 If you want to deny user domains applications to map a memory region as
64 both executable and writable, this is dangerous and the executable
65 should be reported in bugzilla, you must turn on the deny_execmem bool‐
66 ean. Enabled by default.
67 setsebool -P deny_execmem 1
69 If you want to allow all domains to execute in fips_mode, you must turn
73 on the fips_mode boolean. Enabled by default.
74 setsebool -P fips_mode 1
76 If you want to control the ability to mmap a low area of the address
80 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
81 the mmap_low_allowed boolean. Disabled by default.
82 setsebool -P mmap_low_allowed 1
84 If you want to disable kernel module loading, you must turn on the
88 secure_mode_insmod boolean. Enabled by default.
89 setsebool -P secure_mode_insmod 1
91 If you want to allow unconfined executables to make their heap memory
95 executable. Doing this is a really bad idea. Probably indicates a
96 badly coded executable, but could indicate an attack. This executable
97 should be reported in bugzilla, you must turn on the selin‐
98 uxuser_execheap boolean. Disabled by default.
99 setsebool -P selinuxuser_execheap 1
101 If you want to allow unconfined executables to make their stack exe‐
105 cutable. This should never, ever be necessary. Probably indicates a
106 badly coded executable, but could indicate an attack. This executable
107 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
108 stack boolean. Enabled by default.
109 setsebool -P selinuxuser_execstack 1

115 The SELinux process type keepalived_unconfined_script_t can manage
116 files labeled with the following file types. The paths listed are the
117 default paths for these file types. Note the processes UID still need
118 to have DAC permissions.
119 file_type
121 all files on the system
123
126 SELinux requires files to have an extended attribute to define the file
127 type.
128 You can see the context of a file using the -Z option to ls
130 Policy governs the access confined processes have to these files.
132 SELinux keepalived_unconfined_script policy is very flexible allowing
133 users to setup their keepalived_unconfined_script processes in as
134 secure a method as possible.
135 The following file types are defined for keepalived_unconfined_script:
137 keepalived_unconfined_script_exec_t
141 - Set files with the keepalived_unconfined_script_exec_t type, if you
143 want to transition an executable to the keepalived_unconfined_script_t
144 domain.
145 Note: File context can be temporarily modified with the chcon command.
149 If you want to permanently change the file context you need to use the
150 semanage fcontext command. This will modify the SELinux labeling data‐
151 base. You will need to use restorecon to apply the labels.
152
155 semanage fcontext can also be used to manipulate default file context
156 mappings.
157 semanage permissive can also be used to manipulate whether or not a
159 process type is permissive.
160 semanage module can also be used to enable/disable/install/remove pol‐
162 icy modules.
163 semanage boolean can also be used to manipulate the booleans
165 system-config-selinux is a GUI tool available to customize SELinux pol‐
168 icy settings.
