6 sge_execd_selinux - Security Enhanced Linux Policy for the sge_execd
7 processes
8
10 Security-Enhanced Linux secures the sge_execd processes via flexible
11 mandatory access control.
12 The sge_execd processes execute with the sge_execd_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 For example:
18 ps -eZ | grep sge_execd_t
20
24 The sge_execd_t SELinux type can be entered via the sge_execd_exec_t
25 file type.
26 The default entrypoint paths for the sge_execd_t domain are the follow‐
28 ing:
29 /usr/bin/sge_execd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 sge_execd policy is very flexible allowing users to setup their sge_ex‐
40 ecd processes in as secure a method as possible.
41 The following process types are defined for sge_execd:
43 sge_execd_t
45 Note: semanage permissive -a sge_execd_t can be used to make the
47 process type sge_execd_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. sge_ex‐
54 ecd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run sge_execd with the tightest access
56 possible.
57 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1
79
83 The SELinux process type sge_execd_t can manage files labeled with the
84 following file types. The paths listed are the default paths for these
85 file types. Note the processes UID still need to have DAC permissions.

149 SELinux requires files to have an extended attribute to define the file
150 type.
151 You can see the context of a file using the -Z option to ls
153 Policy governs the access confined processes have to these files.
155 SELinux sge_execd policy is very flexible allowing users to setup their
156 sge_execd processes in as secure a method as possible.
157 STANDARD FILE CONTEXT
159 SELinux defines the file context types for the sge_execd, if you wanted
161 to store files with these types in a different paths, you need to exe‐
162 cute the semanage command to specify alternate labeling and then use
163 restorecon to put the labels on disk.
164 semanage fcontext -a -t sge_execd_exec_t '/srv/sge_execd/content(/.*)?'
166 restorecon -R -v /srv/mysge_execd_content
167 Note: SELinux often uses regular expressions to specify labels that
169 match multiple files.
170 The following file types are defined for sge_execd:
172 sge_execd_exec_t
176 - Set files with the sge_execd_exec_t type, if you want to transition
178 an executable to the sge_execd_t domain.
179 Note: File context can be temporarily modified with the chcon command.
183 If you want to permanently change the file context you need to use the
184 semanage fcontext command. This will modify the SELinux labeling data‐
185 base. You will need to use restorecon to apply the labels.
186
189 semanage fcontext can also be used to manipulate default file context
190 mappings.
191 semanage permissive can also be used to manipulate whether or not a
193 process type is permissive.
194 semanage module can also be used to enable/disable/install/remove pol‐
196 icy modules.
197 semanage boolean can also be used to manipulate the booleans
199 system-config-selinux is a GUI tool available to customize SELinux pol‐
202 icy settings.
