6 sge_job_selinux - Security Enhanced Linux Policy for the sge_job pro‐
7 cesses
8
10 Security-Enhanced Linux secures the sge_job processes via flexible
11 mandatory access control.
12
13 The sge_job processes execute with the sge_job_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 sge_job_t
20
21
22
24 The sge_job_t SELinux type can be entered via the shell_exec_t,
25 sge_job_exec_t file types.
26
27 The default entrypoint paths for the sge_job_t domain are the follow‐
28 ing:
29
30 /bin/d?ash, /bin/zsh.*, /bin/ksh.*, /usr/bin/d?ash, /usr/bin/ksh.*,
31 /usr/bin/zsh.*, /bin/esh, /bin/mksh, /bin/sash, /bin/tcsh, /bin/yash,
32 /bin/bash, /bin/fish, /bin/bash2, /usr/bin/esh, /usr/bin/sash,
33 /usr/bin/tcsh, /usr/bin/yash, /usr/bin/mksh, /usr/bin/fish,
34 /usr/bin/bash, /sbin/nologin, /usr/sbin/sesh, /usr/bin/bash2,
35 /usr/sbin/smrsh, /usr/bin/scponly, /usr/sbin/nologin,
36 /usr/libexec/sesh, /usr/sbin/scponlyc, /usr/bin/git-shell,
37 /usr/libexec/sudo/sesh, /usr/bin/cockpit-bridge, /usr/libexec/cockpit-
38 agent, /usr/libexec/git-core/git-shell

41 SELinux defines process types (domains) for each process running on the
42 system
43
44 You can see the context of a process using the -Z option to ps
45
46 Policy governs the access confined processes have to files. SELinux
47 sge_job policy is very flexible allowing users to setup their sge_job
48 processes in as secure a method as possible.
49
50 The following process types are defined for sge_job:
51
52 sge_job_t, sge_job_ssh_t
53
54 Note: semanage permissive -a sge_job_t can be used to make the process
55 type sge_job_t permissive. SELinux does not deny access to permissive
56 process types, but the AVC (SELinux denials) messages are still gener‐
57 ated.
58
59
61 SELinux policy is customizable based on least access required. sge_job
62 policy is extremely flexible and has several booleans that allow you to
63 manipulate the policy and run sge_job with the tightest access possi‐
64 ble.
65
66
67
68 If you want to deny user domains applications to map a memory region as
69 both executable and writable, this is dangerous and the executable
70 should be reported in bugzilla, you must turn on the deny_execmem bool‐
71 ean. Enabled by default.

94 executed with systemd.log_target=kmsg parameter, you must turn on the
95 domain_can_write_kmsg boolean. Disabled by default.

102 you must turn on the domain_fd_use boolean. Enabled by default.
103
104 setsebool -P domain_fd_use 1
105
106
107
108 If you want to allow all domains to have the kernel load modules, you
109 must turn on the domain_kernel_load_modules boolean. Disabled by
110 default.

113
114

131 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
132 the mmap_low_allowed boolean. Disabled by default.
133

212 The SELinux process type sge_job_t can manage files labeled with the
213 following file types. The paths listed are the default paths for these
214 file types. Note the processes UID still need to have DAC permissions.
215
216 file_type
217
218 all files on the system
219
220
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224
225 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227
228 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
230
231 semanage boolean can also be used to manipulate the booleans
232
