6 policykit_resolve_selinux - Security Enhanced Linux Policy for the pol‐
7 icykit_resolve processes
8
10 Security-Enhanced Linux secures the policykit_resolve processes via
11 flexible mandatory access control.
12 The policykit_resolve processes execute with the policykit_resolve_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep policykit_resolve_t
20
24 The policykit_resolve_t SELinux type can be entered via the poli‐
25 cykit_resolve_exec_t file type.
26 The default entrypoint paths for the policykit_resolve_t domain are the
28 following:
29 /usr/libexec/polkit-resolve-exe-helper.*, /usr/lib/policykit/polkit-
31 resolve-exe-helper.*
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 policykit_resolve policy is very flexible allowing users to setup their
41 policykit_resolve processes in as secure a method as possible.
42 The following process types are defined for policykit_resolve:
44 policykit_resolve_t
46 Note: semanage permissive -a policykit_resolve_t can be used to make
48 the process type policykit_resolve_t permissive. SELinux does not deny
49 access to permissive process types, but the AVC (SELinux denials) mes‐
50 sages are still generated.
51
54 SELinux policy is customizable based on least access required. poli‐
55 cykit_resolve policy is extremely flexible and has several booleans
56 that allow you to manipulate the policy and run policykit_resolve with
57 the tightest access possible.
58 If you want to allow users to resolve user passwd entries directly from
62 ldap rather then using a sssd server, you must turn on the authlo‐
63 gin_nsswitch_use_ldap boolean. Disabled by default.
64 setsebool -P authlogin_nsswitch_use_ldap 1
66 If you want to allow all daemons the ability to read/write terminals,
70 you must turn on the daemons_use_tty boolean. Disabled by default.
71 setsebool -P daemons_use_tty 1
73 If you want to deny any process from ptracing or debugging any other
77 processes, you must turn on the deny_ptrace boolean. Enabled by
78 default.
79 setsebool -P deny_ptrace 1
81 If you want to allow any process to mmap any file on system with
85 attribute file_type, you must turn on the domain_can_mmap_files bool‐
86 ean. Enabled by default.
87 setsebool -P domain_can_mmap_files 1
89 If you want to allow all domains write to kmsg_device, while kernel is
93 executed with systemd.log_target=kmsg parameter, you must turn on the
94 domain_can_write_kmsg boolean. Disabled by default.
95 setsebool -P domain_can_write_kmsg 1
97 If you want to allow all domains to use other domains file descriptors,
101 you must turn on the domain_fd_use boolean. Enabled by default.
102 setsebool -P domain_fd_use 1
104 If you want to allow all domains to have the kernel load modules, you
108 must turn on the domain_kernel_load_modules boolean. Disabled by
109 default.
110 setsebool -P domain_kernel_load_modules 1
112 If you want to allow all domains to execute in fips_mode, you must turn
116 on the fips_mode boolean. Enabled by default.
117 setsebool -P fips_mode 1
119 If you want to enable reading of urandom for all domains, you must turn
123 on the global_ssp boolean. Disabled by default.
124 setsebool -P global_ssp 1
126 If you want to allow confined applications to run with kerberos, you
130 must turn on the kerberos_enabled boolean. Enabled by default.
131 setsebool -P kerberos_enabled 1
133 If you want to allow system to run with NIS, you must turn on the
137 nis_enabled boolean. Disabled by default.
138 setsebool -P nis_enabled 1
140 If you want to allow confined applications to use nscd shared memory,
144 you must turn on the nscd_use_shm boolean. Disabled by default.
145 setsebool -P nscd_use_shm 1
147
151 SELinux requires files to have an extended attribute to define the file
152 type.
153 You can see the context of a file using the -Z option to ls
155 Policy governs the access confined processes have to these files.
157 SELinux policykit_resolve policy is very flexible allowing users to
158 setup their policykit_resolve processes in as secure a method as possi‐
159 ble.
160 The following file types are defined for policykit_resolve:
162 policykit_resolve_exec_t
166 - Set files with the policykit_resolve_exec_t type, if you want to
168 transition an executable to the policykit_resolve_t domain.
169 Paths:
172 /usr/libexec/polkit-resolve-exe-helper.*, /usr/lib/poli‐
173 cykit/polkit-resolve-exe-helper.*
174 Note: File context can be temporarily modified with the chcon command.
177 If you want to permanently change the file context you need to use the
178 semanage fcontext command. This will modify the SELinux labeling data‐
179 base. You will need to use restorecon to apply the labels.
180
183 semanage fcontext can also be used to manipulate default file context
184 mappings.
185 semanage permissive can also be used to manipulate whether or not a
187 process type is permissive.
188 semanage module can also be used to enable/disable/install/remove pol‐
190 icy modules.
191 semanage boolean can also be used to manipulate the booleans
193 system-config-selinux is a GUI tool available to customize SELinux pol‐
196 icy settings.
