NAME

6       sftpd_selinux - Security Enhanced Linux Policy for the sftpd processes
7

DESCRIPTION

9       Security-Enhanced Linux secures the sftpd processes via flexible manda‐
10       tory access control.
11
12       The sftpd processes execute with the  sftpd_t  SELinux  type.  You  can
13       check  if  you have these processes running by executing the ps command
14       with the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep sftpd_t

PROCESS TYPES

23       SELinux defines process types (domains) for each process running on the
24       system
25
26       You can see the context of a process using the -Z option to ps
27
28       Policy  governs  the  access confined processes have to files.  SELinux
29       sftpd policy is very flexible allowing users to setup their sftpd  pro‐
30       cesses in as secure a method as possible.
31
32       The following process types are defined for sftpd:
33
34       sftpd_t
35
36       Note:  semanage  permissive  -a sftpd_t can be used to make the process
37       type sftpd_t permissive. SELinux does not  deny  access  to  permissive
38       process  types, but the AVC (SELinux denials) messages are still gener‐
39       ated.

BOOLEANS

43       SELinux policy is customizable based on least access  required.   sftpd
44       policy is extremely flexible and has several booleans that allow you to
45       manipulate the policy and run sftpd with the tightest access possible.
46
47
48
49       If you want to deny any process from ptracing or  debugging  any  other
50       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
51       default.
52
53       setsebool -P deny_ptrace 1
54
55
56
57       If you want to allow any process  to  mmap  any  file  on  system  with
58       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
59       ean. Enabled by default.
60
61       setsebool -P domain_can_mmap_files 1
62
63
64
65       If you want to allow all domains write to kmsg_device, while kernel  is
66       executed  with  systemd.log_target=kmsg parameter, you must turn on the
67       domain_can_write_kmsg boolean. Disabled by default.
68
69       setsebool -P domain_can_write_kmsg 1
70
71
72
73       If you want to allow all domains to use other domains file descriptors,
74       you must turn on the domain_fd_use boolean. Enabled by default.
75
76       setsebool -P domain_fd_use 1
77
78
79
80       If  you  want to allow all domains to have the kernel load modules, you
81       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
82       default.
83
84       setsebool -P domain_kernel_load_modules 1
85
86
87
88       If you want to allow all domains to execute in fips_mode, you must turn
89       on the fips_mode boolean. Enabled by default.
90
91       setsebool -P fips_mode 1
92
93
94
95       If you want to enable reading of urandom for all domains, you must turn
96       on the global_ssp boolean. Disabled by default.
97
98       setsebool -P global_ssp 1
99
100
101
102       If  you want to support ecryptfs home directories, you must turn on the
103       use_ecryptfs_home_dirs boolean. Disabled by default.
104
105       setsebool -P use_ecryptfs_home_dirs 1
106
107
108
109       If you want to support fusefs home directories, you must  turn  on  the
110       use_fusefs_home_dirs boolean. Disabled by default.
111
112       setsebool -P use_fusefs_home_dirs 1
113
114
115
116       If  you  want  to  support  NFS  home directories, you must turn on the
117       use_nfs_home_dirs boolean. Disabled by default.
118
119       setsebool -P use_nfs_home_dirs 1
120
121
122
123       If you want to support SAMBA home directories, you  must  turn  on  the
124       use_samba_home_dirs boolean. Disabled by default.
125
126       setsebool -P use_samba_home_dirs 1

MANAGED FILES

131       The SELinux process type sftpd_t can manage files labeled with the fol‐
132       lowing file types.  The paths listed are the default  paths  for  these
133       file types.  Note the processes UID still need to have DAC permissions.
134
135       user_home_t
136
137            /home/[^/]+/.+
138
139       user_tmp_t
140
141            /dev/shm/mono.*
142            /var/run/user(/.*)?
143            /tmp/.X11-unix(/.*)?
144            /tmp/.ICE-unix(/.*)?
145            /dev/shm/pulse-shm.*
146            /tmp/.X0-lock
147            /tmp/hsperfdata_root
148            /var/tmp/hsperfdata_root
149            /home/[^/]+/tmp
150            /home/[^/]+/.tmp
151            /tmp/gconfd-[^/]+

COMMANDS

155       semanage  fcontext  can also be used to manipulate default file context
156       mappings.
157
158       semanage permissive can also be used to manipulate  whether  or  not  a
159       process type is permissive.
160
161       semanage  module can also be used to enable/disable/install/remove pol‐
162       icy modules.
163

165
