6 samba_unconfined_net_selinux - Security Enhanced Linux Policy for the
7 samba_unconfined_net processes
8
10 Security-Enhanced Linux secures the samba_unconfined_net processes via
11 flexible mandatory access control.
12 The samba_unconfined_net processes execute with the samba_uncon‐
14 fined_net_t SELinux type. You can check if you have these processes
15 running by executing the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep samba_unconfined_net_t
20
24 The samba_unconfined_net_t SELinux type can be entered via the
25 file_type, samba_net_exec_t, unlabeled_t, proc_type, filesystem_type,
26 mtrr_device_t, sysctl_type file types.
27 The default entrypoint paths for the samba_unconfined_net_t domain are
29 the following:
30 all files on the system, /usr/bin/net, /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 samba_unconfined_net policy is very flexible allowing users to setup
41 their samba_unconfined_net processes in as secure a method as possible.
42 The following process types are defined for samba_unconfined_net:
44 samba_unconfined_net_t
46 Note: semanage permissive -a samba_unconfined_net_t can be used to make
48 the process type samba_unconfined_net_t permissive. SELinux does not
49 deny access to permissive process types, but the AVC (SELinux denials)
50 messages are still generated.
51
54 SELinux policy is customizable based on least access required.
55 samba_unconfined_net policy is extremely flexible and has several bool‐
56 eans that allow you to manipulate the policy and run samba_uncon‐
57 fined_net with 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 samba_unconfined_net_t can manage files
159 labeled with the following file types. The paths listed are the
160 default paths for these file types. Note the processes UID still need
161 to have DAC 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.
