NAME

6       sysadm_su_selinux  -  Security  Enhanced Linux Policy for the sysadm_su
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the sysadm_su  processes  via  flexible
11       mandatory access control.
12
13       The  sysadm_su processes execute with the sysadm_su_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 sysadm_su_t
20
21
22

ENTRYPOINTS

24       The  sysadm_su_t  SELinux  type  can  be entered via the su_exec_t file
25       type.
26
27       The default entrypoint paths for the sysadm_su_t domain are the follow‐
28       ing:
29
30       /usr/(local/)?bin/ksu, /bin/su, /usr/bin/kdesu
31

PROCESS TYPES

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       sysadm_su  policy  is  very  flexible  allowing  users  to  setup their
40       sysadm_su processes in as secure a method as possible.
41
42       The following process types are defined for sysadm_su:
43
44       sysadm_su_t, sysadm_sudo_t
45
46       Note: semanage permissive -a  sysadm_su_t  can  be  used  to  make  the
47       process  type  sysadm_su_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       sysadm_su policy is extremely flexible and has  several  booleans  that
55       allow  you to manipulate the policy and run sysadm_su with the tightest
56       access possible.
57
58
59
60       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.

68       must turn on the allow_kerberos boolean. Enabled by default.
69
70       setsebool -P allow_kerberos 1
71
72
73

78
79
80
81       If  you want to allow sysadm to debug or ptrace all processes, you must

92
93
94
95       If  you  want to allow all domains to have the kernel load modules, you
96       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
97       default.

99       setsebool -P domain_kernel_load_modules 1
100
101
102

104       on the fips_mode boolean. Enabled by default.
105
106       setsebool -P fips_mode 1
107
108
109
110       If you want to enable reading of urandom for all domains, you must turn
111       on the global_ssp boolean. Disabled by default.
112
113       setsebool -P global_ssp 1
114
115
116
117       If  you  want to allow confined applications to use nscd shared memory,
118       you must turn on the nscd_use_shm boolean. Enabled by default.
119
120       setsebool -P nscd_use_shm 1
121
122
123
124       If you want to support NFS home  directories,  you  must  turn  on  the
125       use_nfs_home_dirs boolean. Disabled by default.
126
127       setsebool -P use_nfs_home_dirs 1
128
129
130
131       If  you  want  to  support SAMBA home directories, you must turn on the
132       use_samba_home_dirs boolean. Disabled by default.
133
134       setsebool -P use_samba_home_dirs 1

MANAGED FILES

139       The SELinux process type sysadm_su_t can manage files labeled with  the
140       following file types.  The paths listed are the default paths for these
141       file types.  Note the processes UID still need to have DAC permissions.
