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 file_type, unla‐
25 beled_t, proc_type, filesystem_type, sge_execd_exec_t, mtrr_device_t,
26 sysctl_type file types.
27 The default entrypoint paths for the sge_execd_t domain are the follow‐
29 ing:
30 all files on the system, /usr/bin/sge_execd, /dev/cpu/mtrr
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 sge_execd policy is very flexible allowing users to setup their
41 sge_execd processes in as secure a method as possible.
42 The following process types are defined for sge_execd:
44 sge_execd_t
46 Note: semanage permissive -a sge_execd_t can be used to make the
48 process type sge_execd_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required.
55 sge_execd policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run sge_execd with the tightest
57 access possible.
58 If you want to allow all daemons to write corefiles to /, you must turn
62 on the allow_daemons_dump_core boolean. Disabled by default.

114 If you want to allow unconfined executables to make their stack exe‐
118 cutable. This should never, ever be necessary. Probably indicates a
119 badly coded executable, but could indicate an attack. This executable
120 should be reported in bugzilla), you must turn on the allow_execstack
121 boolean. Enabled by default.
122 setsebool -P allow_execstack 1
124 If you want to allow confined applications to run with kerberos, you
128 must turn on the allow_kerberos boolean. Enabled by default.
129 setsebool -P allow_kerberos 1

149 daemons_enable_cluster_mode boolean. Disabled by default.
150 setsebool -P daemons_enable_cluster_mode 1
152 If you want to allow all domains to have the kernel load modules, you
156 must turn on the domain_kernel_load_modules boolean. Disabled by
157 default.
158 setsebool -P domain_kernel_load_modules 1
160 If you want to allow all domains to execute in fips_mode, you must turn
164 on the fips_mode boolean. Enabled by default.
165 setsebool -P fips_mode 1
167 If you want to enable reading of urandom for all domains, you must turn
171 on the global_ssp boolean. Disabled by default.
172 setsebool -P global_ssp 1
174 If you want to enable support for upstart as the init program, you must
178 turn on the init_upstart boolean. Enabled by default.
179 setsebool -P init_upstart 1
181 If you want to allow certain domains to map low memory in the kernel,
185 you must turn on the mmap_low_allowed boolean. Disabled by default.
186 setsebool -P mmap_low_allowed 1

192 you must turn on the nscd_use_shm boolean. Enabled by default.
193 setsebool -P nscd_use_shm 1
195 If you want to boolean to determine whether the system permits loading
199 policy, setting enforcing mode, and changing boolean values. Set this
200 to true and you have to reboot to set it back, you must turn on the
201 secure_mode_policyload boolean. Disabled by default.

226
230 The SELinux process type sge_execd_t can manage files labeled with the
231 following file types. The paths listed are the default paths for these
232 file types. Note the processes UID still need to have DAC permissions.
233 file_type
235 all files on the system
237
240 SELinux requires files to have an extended attribute to define the file
241 type.
242 You can see the context of a file using the -Z option to ls
244 Policy governs the access confined processes have to these files.
246 SELinux sge_execd policy is very flexible allowing users to setup their
247 sge_execd processes in as secure a method as possible.
248 The following file types are defined for sge_execd:
250 sge_execd_exec_t
254 - Set files with the sge_execd_exec_t type, if you want to transition
256 an executable to the sge_execd_t domain.
257 Note: File context can be temporarily modified with the chcon command.
261 If you want to permanently change the file context you need to use the
262 semanage fcontext command. This will modify the SELinux labeling data‐
263 base. You will need to use restorecon to apply the labels.
264
267 semanage fcontext can also be used to manipulate default file context
268 mappings.
269 semanage permissive can also be used to manipulate whether or not a
271 process type is permissive.
272 semanage module can also be used to enable/disable/install/remove pol‐
274 icy modules.
275 semanage boolean can also be used to manipulate the booleans
277 system-config-selinux is a GUI tool available to customize SELinux pol‐
280 icy settings.
