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 do‐
29 main 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. Disabled by default.
67 setsebool -P deny_execmem 1
69 If you want to control the ability to mmap a low area of the address
73 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
74 the mmap_low_allowed boolean. Disabled by default.
75 setsebool -P mmap_low_allowed 1
77 If you want to disable kernel module loading, you must turn on the se‐
81 cure_mode_insmod boolean. Disabled by default.
82 setsebool -P secure_mode_insmod 1
84 If you want to allow unconfined executables to make their heap memory
88 executable. Doing this is a really bad idea. Probably indicates a
89 badly coded executable, but could indicate an attack. This executable
90 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
91 echeap boolean. Disabled by default.
92 setsebool -P selinuxuser_execheap 1
94 If you want to allow unconfined executables to make their stack exe‐
98 cutable. This should never, ever be necessary. Probably indicates a
99 badly coded executable, but could indicate an attack. This executable
100 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
101 stack boolean. Enabled by default.
102 setsebool -P selinuxuser_execstack 1
104
108 The SELinux process type keepalived_unconfined_script_t can manage
109 files labeled with the following file types. The paths listed are the
110 default paths for these file types. Note the processes UID still need
111 to have DAC permissions.
112 file_type
114 all files on the system
116
119 SELinux requires files to have an extended attribute to define the file
120 type.
121 You can see the context of a file using the -Z option to ls
123 Policy governs the access confined processes have to these files.
125 SELinux keepalived_unconfined_script policy is very flexible allowing
126 users to setup their keepalived_unconfined_script processes in as se‐
127 cure a method as possible.
128 STANDARD FILE CONTEXT
130 SELinux defines the file context types for the keepalived_uncon‐
132 fined_script, if you wanted to store files with these types in a dif‐
133 ferent paths, you need to execute the semanage command to specify al‐
134 ternate labeling and then use restorecon to put the labels on disk.
135 semanage fcontext -a -t keepalived_unconfined_script_exec_t
137 '/srv/keepalived_unconfined_script/content(/.*)?'
138 restorecon -R -v /srv/mykeepalived_unconfined_script_content
139 Note: SELinux often uses regular expressions to specify labels that
141 match multiple files.
142 The following file types are defined for keepalived_unconfined_script:
144 keepalived_unconfined_script_exec_t
148 - Set files with the keepalived_unconfined_script_exec_t type, if you
150 want to transition an executable to the keepalived_unconfined_script_t
151 domain.
152 Note: File context can be temporarily modified with the chcon command.
156 If you want to permanently change the file context you need to use the
157 semanage fcontext command. This will modify the SELinux labeling data‐
158 base. You will need to use restorecon to apply the labels.
159
162 semanage fcontext can also be used to manipulate default file context
163 mappings.
164 semanage permissive can also be used to manipulate whether or not a
166 process type is permissive.
167 semanage module can also be used to enable/disable/install/remove pol‐
169 icy modules.
170 semanage boolean can also be used to manipulate the booleans
172 system-config-selinux is a GUI tool available to customize SELinux pol‐
175 icy settings.
