6 smbmount_selinux - Security Enhanced Linux Policy for the smbmount pro‐
7 cesses
8
10 Security-Enhanced Linux secures the smbmount processes via flexible
11 mandatory access control.
12
13 The smbmount processes execute with the smbmount_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
17 For example:
18
19 ps -eZ | grep smbmount_t
20
21
22
24 The smbmount_t SELinux type can be entered via the smbmount_exec_t file
25 type.
26
27 The default entrypoint paths for the smbmount_t domain are the follow‐
28 ing:
29
30 /usr/bin/smbmnt, /usr/bin/smbmount
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 smbmount policy is very flexible allowing users to setup their smbmount
40 processes in as secure a method as possible.
41
42 The following process types are defined for smbmount:
43
44 smbmount_t
45
46 Note: semanage permissive -a smbmount_t can be used to make the process
47 type smbmount_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. smb‐
54 mount policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run smbmount with the tightest access
56 possible.
57
58
59
60 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
63 setsebool -P fips_mode 1
64
65
66
68 The SELinux process type smbmount_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

72 krb5_host_rcache_t
73
74 /var/tmp/krb5_0.rcache2
75 /var/cache/krb5rcache(/.*)?
76 /var/tmp/nfs_0
77 /var/tmp/DNS_25
78 /var/tmp/host_0

93 /etc/samba/passdb.tdb

99 SELinux requires files to have an extended attribute to define the file
100 type.
101
102 You can see the context of a file using the -Z option to ls
103
104 Policy governs the access confined processes have to these files.
105 SELinux smbmount policy is very flexible allowing users to setup their
106 smbmount processes in as secure a method as possible.
107
108 The following file types are defined for smbmount:
109
110
111
112 smbmount_exec_t
113
114 - Set files with the smbmount_exec_t type, if you want to transition an
115 executable to the smbmount_t domain.
116
117
118 Paths:
119 /usr/bin/smbmnt, /usr/bin/smbmount
120
121
122 Note: File context can be temporarily modified with the chcon command.
123 If you want to permanently change the file context you need to use the
124 semanage fcontext command. This will modify the SELinux labeling data‐
125 base. You will need to use restorecon to apply the labels.
126
127
129 semanage fcontext can also be used to manipulate default file context
130 mappings.
131
132 semanage permissive can also be used to manipulate whether or not a
133 process type is permissive.
134
135 semanage module can also be used to enable/disable/install/remove pol‐
136 icy modules.
137
138 semanage boolean can also be used to manipulate the booleans
139
140
141 system-config-selinux is a GUI tool available to customize SELinux pol‐
142 icy settings.
