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 allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62 setsebool -P allow_domain_fd_use 1
64 If you want to allow unconfined executables to map a memory region as
68 both executable and writable, this is dangerous and the executable
69 should be reported in bugzilla), you must turn on the allow_execmem
70 boolean. Enabled by default.
71 setsebool -P allow_execmem 1
73 If you want to allow all unconfined executables to use libraries
77 requiring text relocation that are not labeled textrel_shlib_t), you
78 must turn on the allow_execmod boolean. Enabled by default.
79 setsebool -P allow_execmod 1
81 If you want to allow mplayer executable stack, you must turn on the
85 allow_mplayer_execstack boolean. Disabled by default.
86 setsebool -P allow_mplayer_execstack 1
88 If you want to allow sysadm to debug or ptrace all processes, you must
92 turn on the allow_ptrace boolean. Disabled by default.
93 setsebool -P allow_ptrace 1
95 If you want to allow all domains to have the kernel load modules, you
99 must turn on the domain_kernel_load_modules boolean. Disabled by
100 default.
101 setsebool -P domain_kernel_load_modules 1
103 If you want to allow all domains to execute in fips_mode, you must turn
107 on the fips_mode boolean. Enabled by default.
108 setsebool -P fips_mode 1
110 If you want to enable reading of urandom for all domains, you must turn
114 on the global_ssp boolean. Disabled by default.
115 setsebool -P global_ssp 1
117 If you want to support NFS home directories, you must turn on the
121 use_nfs_home_dirs boolean. Disabled by default.
122 setsebool -P use_nfs_home_dirs 1
124 If you want to support SAMBA home directories, you must turn on the
128 use_samba_home_dirs boolean. Disabled by default.
129 setsebool -P use_samba_home_dirs 1

135 The SELinux process type mencoder_t can manage files labeled with the
136 following file types. The paths listed are the default paths for these
137 file types. Note the processes UID still need to have DAC permissions.
138 cifs_t
140 initrc_tmp_t
143 mnt_t
146 /mnt(/[^/]*)
148 /mnt(/[^/]*)?
149 /rhev(/[^/]*)?
150 /media(/[^/]*)
151 /media(/[^/]*)?
152 /etc/rhgb(/.*)?
153 /media/.hal-.*
154 /net
155 /afs
156 /rhev
157 /misc
158 mplayer_home_t
160 /home/[^/]*/.mplayer(/.*)?
162 /home/staff/.mplayer(/.*)?
163 nfs_t
165 tmp_t
168 /tmp
170 /usr/tmp
171 /var/tmp
172 /tmp-inst
173 /var/tmp-inst
174 /var/tmp/vi.recover

178 SELinux requires files to have an extended attribute to define the file
179 type.
180 You can see the context of a file using the -Z option to ls
182 Policy governs the access confined processes have to these files.
184 SELinux mencoder policy is very flexible allowing users to setup their
185 mencoder processes in as secure a method as possible.
186 The following file types are defined for mencoder:
188 mencoder_exec_t
192 - Set files with the mencoder_exec_t type, if you want to transition an
194 executable to the mencoder_t domain.
195 Note: File context can be temporarily modified with the chcon command.
199 If you want to permanently change the file context you need to use the
200 semanage fcontext command. This will modify the SELinux labeling data‐
201 base. You will need to use restorecon to apply the labels.
202
205 semanage fcontext can also be used to manipulate default file context
206 mappings.
207 semanage permissive can also be used to manipulate whether or not a
209 process type is permissive.
210 semanage module can also be used to enable/disable/install/remove pol‐
212 icy modules.
213 semanage boolean can also be used to manipulate the booleans
215 system-config-selinux is a GUI tool available to customize SELinux pol‐
218 icy settings.
