6 mencoder_selinux - Security Enhanced Linux Policy for the mencoder pro‐
7 cesses
8
10 Security-Enhanced Linux secures the mencoder processes via flexible
11 mandatory access control.
12 The mencoder processes execute with the mencoder_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep mencoder_t
20
24 The mencoder_t SELinux type can be entered via the mencoder_exec_t file
25 type.
26 The default entrypoint paths for the mencoder_t domain are the follow‐
28 ing:
29 /usr/bin/mencoder
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 mencoder policy is very flexible allowing users to setup their mencoder
40 processes in as secure a method as possible.
41 The following process types are defined for mencoder:
43 mencoder_t
45 Note: semanage permissive -a mencoder_t can be used to make the process
47 type mencoder_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. men‐
54 coder policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run mencoder with the tightest access
56 possible.
57 If you want to deny user domains applications to map a memory region as
61 both executable and writable, this is dangerous and the executable
62 should be reported in bugzilla, you must turn on the deny_execmem bool‐
63 ean. Enabled by default.
64 setsebool -P deny_execmem 1
66 If you want to deny any process from ptracing or debugging any other
70 processes, you must turn on the deny_ptrace boolean. Enabled by
71 default.
72 setsebool -P deny_ptrace 1
74 If you want to allow any process to mmap any file on system with
78 attribute file_type, you must turn on the domain_can_mmap_files bool‐
79 ean. Enabled by default.
80 setsebool -P domain_can_mmap_files 1
82 If you want to allow all domains write to kmsg_device, while kernel is
86 executed with systemd.log_target=kmsg parameter, you must turn on the
87 domain_can_write_kmsg boolean. Disabled by default.
88 setsebool -P domain_can_write_kmsg 1
90 If you want to allow all domains to use other domains file descriptors,
94 you must turn on the domain_fd_use boolean. Enabled by default.
95 setsebool -P domain_fd_use 1
97 If you want to allow all domains to have the kernel load modules, you
101 must turn on the domain_kernel_load_modules boolean. Disabled by
102 default.
103 setsebool -P domain_kernel_load_modules 1
105 If you want to allow all domains to execute in fips_mode, you must turn
109 on the fips_mode boolean. Enabled by default.
110 setsebool -P fips_mode 1
112 If you want to enable reading of urandom for all domains, you must turn
116 on the global_ssp boolean. Disabled by default.
117 setsebool -P global_ssp 1
119 If you want to determine whether mplayer can make its stack executable,
123 you must turn on the mplayer_execstack boolean. Disabled by default.
124 setsebool -P mplayer_execstack 1
126 If you want to allow all unconfined executables to use libraries
130 requiring text relocation that are not labeled textrel_shlib_t, you
131 must turn on the selinuxuser_execmod boolean. Enabled by default.
132 setsebool -P selinuxuser_execmod 1
134 If you want to support NFS home directories, you must turn on the
138 use_nfs_home_dirs boolean. Disabled by default.
139 setsebool -P use_nfs_home_dirs 1
141 If you want to support SAMBA home directories, you must turn on the
145 use_samba_home_dirs boolean. Disabled by default.
146 setsebool -P use_samba_home_dirs 1
148
152 The SELinux process type mencoder_t can manage files labeled with the
153 following file types. The paths listed are the default paths for these
154 file types. Note the processes UID still need to have DAC permissions.
155 cifs_t
157 mplayer_home_t
160 /home/[^/]+/.mplayer(/.*)?
162 nfs_t
164 user_home_t
167 /home/[^/]+/.+
169 user_tmp_t
171 /dev/shm/mono.*
173 /var/run/user(/.*)?
174 /tmp/.X11-unix(/.*)?
175 /tmp/.ICE-unix(/.*)?
176 /dev/shm/pulse-shm.*
177 /tmp/.X0-lock
178 /tmp/hsperfdata_root
179 /var/tmp/hsperfdata_root
180 /home/[^/]+/tmp
181 /home/[^/]+/.tmp
182 /tmp/gconfd-[^/]+
183
186 SELinux requires files to have an extended attribute to define the file
187 type.
188 You can see the context of a file using the -Z option to ls
190 Policy governs the access confined processes have to these files.
192 SELinux mencoder policy is very flexible allowing users to setup their
193 mencoder processes in as secure a method as possible.
194 The following file types are defined for mencoder:
196 mencoder_exec_t
200 - Set files with the mencoder_exec_t type, if you want to transition an
202 executable to the mencoder_t domain.
203 Note: File context can be temporarily modified with the chcon command.
207 If you want to permanently change the file context you need to use the
208 semanage fcontext command. This will modify the SELinux labeling data‐
209 base. You will need to use restorecon to apply the labels.
210
213 semanage fcontext can also be used to manipulate default file context
214 mappings.
215 semanage permissive can also be used to manipulate whether or not a
217 process type is permissive.
218 semanage module can also be used to enable/disable/install/remove pol‐
220 icy modules.
221 semanage boolean can also be used to manipulate the booleans
223 system-config-selinux is a GUI tool available to customize SELinux pol‐
226 icy settings.
