NAME

6       cronjob_selinux  -  Security Enhanced Linux Policy for the cronjob pro‐
7       cesses
8

DESCRIPTION

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

22

ENTRYPOINTS

24       The  cronjob_t  SELinux  type can be entered via the user_cron_spool_t,
25       shell_exec_t file types.
26
27       The default entrypoint paths for the cronjob_t domain are  the  follow‐
28       ing:
29
30       /var/spool/at(/.*)?,     /var/spool/cron,    /bin/d?ash,    /bin/zsh.*,
31       /bin/ksh.*,  /bin/sash,  /bin/tcsh,  /bin/yash,  /bin/mksh,  /bin/fish,
32       /bin/bash,  /bin/bash2,  /usr/bin/fish,  /sbin/nologin, /usr/sbin/sesh,
33       /usr/sbin/smrsh, /usr/bin/scponly, /usr/libexec/sesh,  /usr/sbin/scpon‐
34       lyc, /usr/bin/git-shell, /usr/libexec/git-core/git-shell

PROCESS TYPES

37       SELinux defines process types (domains) for each process running on the
38       system
39
40       You can see the context of a process using the -Z option to ps
41
42       Policy governs the access confined processes have  to  files.   SELinux
43       cronjob  policy  is very flexible allowing users to setup their cronjob
44       processes in as secure a method as possible.
45
46       The following process types are defined for cronjob:
47
48       cronjob_t
49
50       Note: semanage permissive -a cronjob_t can be used to make the  process
51       type  cronjob_t  permissive. SELinux does not deny access to permissive
52       process types, but the AVC (SELinux denials) messages are still  gener‐
53       ated.
54
55

BOOLEANS

57       SELinux policy is customizable based on least access required.  cronjob
58       policy is extremely flexible and has several booleans that allow you to
59       manipulate  the  policy and run cronjob with the tightest access possi‐
60       ble.
61
62
63
64       If you want to allow all domains to use other domains file descriptors,
65       you must turn on the allow_domain_fd_use boolean. Enabled by default.
66
67       setsebool -P allow_domain_fd_use 1
68
69
70
71       If  you want to allow sysadm to debug or ptrace all processes, you must
72       turn on the allow_ptrace boolean. Disabled by default.
73
74       setsebool -P allow_ptrace 1
75
76
77
78       If you want to allow system to run with  NIS,  you  must  turn  on  the
79       allow_ypbind boolean. Disabled by default.
80
81       setsebool -P allow_ypbind 1
82
83
84
85       If  you  want to allow all domains to have the kernel load modules, you
86       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
87       default.
88
89       setsebool -P domain_kernel_load_modules 1
90
91
92
93       If you want to allow all domains to execute in fips_mode, you must turn
94       on the fips_mode boolean. Enabled by default.
95
96       setsebool -P fips_mode 1
97
98
99
100       If you want to enable reading of urandom for all domains, you must turn
101       on the global_ssp boolean. Disabled by default.
102
103       setsebool -P global_ssp 1

MANAGED FILES

108       The  SELinux  process  type cronjob_t can manage files labeled with the
109       following file types.  The paths listed are the default paths for these
110       file types.  Note the processes UID still need to have DAC permissions.
111
112       initrc_tmp_t
113
114
115       mnt_t
116
117            /mnt(/[^/]*)
118            /mnt(/[^/]*)?

120            /media(/[^/]*)
121            /media(/[^/]*)?
122            /etc/rhgb(/.*)?
123            /media/.hal-.*
124            /net
125            /afs

COMMANDS

150       semanage  fcontext  can also be used to manipulate default file context
151       mappings.
152
153       semanage permissive can also be used to manipulate  whether  or  not  a
154       process type is permissive.
155
156       semanage  module can also be used to enable/disable/install/remove pol‐
157       icy modules.
158
159       semanage boolean can also be used to manipulate the booleans
160
161
162       system-config-selinux is a GUI tool available to customize SELinux pol‐
163       icy settings.
