6 unconfined_cronjob_selinux - Security Enhanced Linux Policy for the
7 unconfined_cronjob processes
8
10 Security-Enhanced Linux secures the unconfined_cronjob processes via
11 flexible mandatory access control.
12 The unconfined_cronjob processes execute with the unconfined_cronjob_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 unconfined_cronjob_t
20
24 The unconfined_cronjob_t SELinux type can be entered via the file_type,
25 unlabeled_t, proc_type, filesystem_type, mtrr_device_t, sysctl_type
26 file types.
27 The default entrypoint paths for the unconfined_cronjob_t domain are
29 the following:
30 all files on the system, /dev/cpu/mtrr
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 unconfined_cronjob policy is very flexible allowing users to setup
41 their unconfined_cronjob processes in as secure a method as possible.
42 The following process types are defined for unconfined_cronjob:
44 unconfined_cronjob_t
46 Note: semanage permissive -a unconfined_cronjob_t can be used to make
48 the process type unconfined_cronjob_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. uncon‐
55 fined_cronjob policy is extremely flexible and has several booleans
56 that allow you to manipulate the policy and run unconfined_cronjob with
57 the tightest access possible.
58 If you want to allow all domains to use other domains file descriptors,
62 you must turn on the allow_domain_fd_use boolean. Enabled by default.
63 setsebool -P allow_domain_fd_use 1
65 If you want to allow unconfined executables to make their heap memory
69 executable. Doing this is a really bad idea. Probably indicates a
70 badly coded executable, but could indicate an attack. This executable
71 should be reported in bugzilla, you must turn on the allow_execheap
72 boolean. Disabled by default.
73 setsebool -P allow_execheap 1
75 If you want to allow unconfined executables to map a memory region as
79 both executable and writable, this is dangerous and the executable
80 should be reported in bugzilla), you must turn on the allow_execmem
81 boolean. Enabled by default.
82 setsebool -P allow_execmem 1
84 If you want to allow all unconfined executables to use libraries
88 requiring text relocation that are not labeled textrel_shlib_t), you
89 must turn on the allow_execmod boolean. Enabled by default.
90 setsebool -P allow_execmod 1
92 If you want to allow unconfined executables to make their stack exe‐
96 cutable. This should never, ever be necessary. Probably indicates a
97 badly coded executable, but could indicate an attack. This executable
98 should be reported in bugzilla), you must turn on the allow_execstack
99 boolean. Enabled by default.
100 setsebool -P allow_execstack 1
102 If you want to allow sysadm to debug or ptrace all processes, you must
106 turn on the allow_ptrace boolean. Disabled by default.
107 setsebool -P allow_ptrace 1
109 If you want to allow all domains to have the kernel load modules, you
113 must turn on the domain_kernel_load_modules boolean. Disabled by
114 default.
115 setsebool -P domain_kernel_load_modules 1
117 If you want to allow all domains to execute in fips_mode, you must turn
121 on the fips_mode boolean. Enabled by default.
122 setsebool -P fips_mode 1
124 If you want to enable reading of urandom for all domains, you must turn
128 on the global_ssp boolean. Disabled by default.
129 setsebool -P global_ssp 1
131 If you want to allow certain domains to map low memory in the kernel,
135 you must turn on the mmap_low_allowed boolean. Disabled by default.
136 setsebool -P mmap_low_allowed 1
138 If you want to boolean to determine whether the system permits loading
142 policy, setting enforcing mode, and changing boolean values. Set this
143 to true and you have to reboot to set it back, you must turn on the
144 secure_mode_policyload boolean. Disabled by default.
145 setsebool -P secure_mode_policyload 1
147 If you want to support X userspace object manager, you must turn on the
151 xserver_object_manager boolean. Disabled by default.
152 setsebool -P xserver_object_manager 1

158 The SELinux process type unconfined_cronjob_t can manage files labeled
159 with the following file types. The paths listed are the default paths
160 for these file types. Note the processes UID still need to have DAC
161 permissions.
162 file_type
164 all files on the system
166
169 semanage fcontext can also be used to manipulate default file context
170 mappings.
171 semanage permissive can also be used to manipulate whether or not a
173 process type is permissive.
174 semanage module can also be used to enable/disable/install/remove pol‐
176 icy modules.
177 semanage boolean can also be used to manipulate the booleans
179 system-config-selinux is a GUI tool available to customize SELinux pol‐
182 icy settings.
