6 cifs_helper_selinux - Security Enhanced Linux Policy for the
7 cifs_helper processes
8
10 Security-Enhanced Linux secures the cifs_helper processes via flexible
11 mandatory access control.
12 The cifs_helper processes execute with the cifs_helper_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep cifs_helper_t
20
24 The cifs_helper_t SELinux type can be entered via the
25 cifs_helper_exec_t file type.
26 The default entrypoint paths for the cifs_helper_t domain are the fol‐
28 lowing:
29 /usr/sbin/cifs.idmap, /usr/sbin/cifs.upcall
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 cifs_helper policy is very flexible allowing users to setup their
40 cifs_helper processes in as secure a method as possible.
41 The following process types are defined for cifs_helper:
43 cifs_helper_t
45 Note: semanage permissive -a cifs_helper_t can be used to make the
47 process type cifs_helper_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 cifs_helper policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run cifs_helper with the tight‐
56 est access possible.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64
68 SELinux requires files to have an extended attribute to define the file
69 type.
70 You can see the context of a file using the -Z option to ls
72 Policy governs the access confined processes have to these files.
74 SELinux cifs_helper policy is very flexible allowing users to setup
75 their cifs_helper processes in as secure a method as possible.
76 STANDARD FILE CONTEXT
78 SELinux defines the file context types for the cifs_helper, if you
80 wanted to store files with these types in a different paths, you need
81 to execute the semanage command to specify alternate labeling and then
82 use restorecon to put the labels on disk.
83 semanage fcontext -a -t cifs_helper_exec_t '/srv/cifs_helper/con‐
85 tent(/.*)?'
86 restorecon -R -v /srv/mycifs_helper_content
87 Note: SELinux often uses regular expressions to specify labels that
89 match multiple files.
90 The following file types are defined for cifs_helper:
92 cifs_helper_exec_t
96 - Set files with the cifs_helper_exec_t type, if you want to transition
98 an executable to the cifs_helper_t domain.
99 Paths:
102 /usr/sbin/cifs.idmap, /usr/sbin/cifs.upcall
103 Note: File context can be temporarily modified with the chcon command.
106 If you want to permanently change the file context you need to use the
107 semanage fcontext command. This will modify the SELinux labeling data‐
108 base. You will need to use restorecon to apply the labels.
109
112 semanage fcontext can also be used to manipulate default file context
113 mappings.
114 semanage permissive can also be used to manipulate whether or not a
116 process type is permissive.
117 semanage module can also be used to enable/disable/install/remove pol‐
119 icy modules.
120 semanage boolean can also be used to manipulate the booleans
122 system-config-selinux is a GUI tool available to customize SELinux pol‐
125 icy settings.
