6 usbmuxd_selinux - Security Enhanced Linux Policy for the usbmuxd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the usbmuxd processes via flexible
11 mandatory access control.
12 The usbmuxd processes execute with the usbmuxd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep usbmuxd_t
20
24 The usbmuxd_t SELinux type can be entered via the usbmuxd_exec_t file
25 type.
26 The default entrypoint paths for the usbmuxd_t domain are the follow‐
28 ing:
29 /usr/sbin/usbmuxd
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 usbmuxd policy is very flexible allowing users to setup their usbmuxd
40 processes in as secure a method as possible.
41 The following process types are defined for usbmuxd:
43 usbmuxd_t
45 Note: semanage permissive -a usbmuxd_t can be used to make the process
47 type usbmuxd_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. usbmuxd
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run usbmuxd with the tightest access possi‐
56 ble.
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 confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69 setsebool -P allow_kerberos 1
71 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76 setsebool -P allow_ptrace 1
78 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83 setsebool -P allow_ypbind 1
85 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91 setsebool -P domain_kernel_load_modules 1
93 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98 setsebool -P fips_mode 1
100 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105 setsebool -P global_ssp 1
107 If you want to allow confined applications to use nscd shared memory,
111 you must turn on the nscd_use_shm boolean. Enabled by default.
112 setsebool -P nscd_use_shm 1
114
118 The SELinux process type usbmuxd_t can manage files labeled with the
119 following file types. The paths listed are the default paths for these
120 file types. Note the processes UID still need to have DAC permissions.
121 initrc_tmp_t
123 mnt_t
126 /mnt(/[^/]*)
128 /mnt(/[^/]*)?
129 /rhev(/[^/]*)?
130 /media(/[^/]*)
131 /media(/[^/]*)?
132 /etc/rhgb(/.*)?
133 /media/.hal-.*
134 /net
135 /afs
136 /rhev
137 /misc
138 tmp_t
140 /tmp
142 /usr/tmp
143 /var/tmp
144 /tmp-inst
145 /var/tmp-inst
146 /var/tmp/vi.recover
147 usbmuxd_var_run_t
149 /var/run/usbmuxd.*
151
154 SELinux requires files to have an extended attribute to define the file
155 type.
156 You can see the context of a file using the -Z option to ls
158 Policy governs the access confined processes have to these files.
160 SELinux usbmuxd policy is very flexible allowing users to setup their
161 usbmuxd processes in as secure a method as possible.
162 STANDARD FILE CONTEXT
164 SELinux defines the file context types for the usbmuxd, if you wanted
166 to store files with these types in a diffent paths, you need to execute
167 the semanage command to sepecify alternate labeling and then use
168 restorecon to put the labels on disk.
169 semanage fcontext -a -t usbmuxd_var_run_t '/srv/myusbmuxd_con‐
171 tent(/.*)?'
172 restorecon -R -v /srv/myusbmuxd_content
173 Note: SELinux often uses regular expressions to specify labels that
175 match multiple files.
176 The following file types are defined for usbmuxd:
178 usbmuxd_exec_t
182 - Set files with the usbmuxd_exec_t type, if you want to transition an
184 executable to the usbmuxd_t domain.
185 usbmuxd_var_run_t
189 - Set files with the usbmuxd_var_run_t type, if you want to store the
191 usbmuxd files under the /run or /var/run directory.
192 Note: File context can be temporarily modified with the chcon command.
196 If you want to permanently change the file context you need to use the
197 semanage fcontext command. This will modify the SELinux labeling data‐
198 base. You will need to use restorecon to apply the labels.
199
202 semanage fcontext can also be used to manipulate default file context
203 mappings.
204 semanage permissive can also be used to manipulate whether or not a
206 process type is permissive.
207 semanage module can also be used to enable/disable/install/remove pol‐
209 icy modules.
210 semanage boolean can also be used to manipulate the booleans
212 system-config-selinux is a GUI tool available to customize SELinux pol‐
215 icy settings.
