6 condor_master_selinux - Security Enhanced Linux Policy for the con‐
7 dor_master processes
8
10 Security-Enhanced Linux secures the condor_master processes via flexi‐
11 ble mandatory access control.
12 The condor_master processes execute with the condor_master_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep condor_master_t
20
24 The condor_master_t SELinux type can be entered via the file_type, con‐
25 dor_master_exec_t, unlabeled_t, proc_type, filesystem_type,
26 mtrr_device_t, sysctl_type file types.
27 The default entrypoint paths for the condor_master_t domain are the
29 following:
30 all files on the system, /usr/sbin/condor_master, /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 condor_master policy is very flexible allowing users to setup their
41 condor_master processes in as secure a method as possible.
42 The following process types are defined for condor_master:
44 condor_master_t
46 Note: semanage permissive -a condor_master_t can be used to make the
48 process type condor_master_t permissive. SELinux does not deny access
49 to permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required. con‐
55 dor_master policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run condor_master with the
57 tightest access possible.

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
131 If you want to allow sysadm to debug or ptrace all processes, you must
135 turn on the allow_ptrace boolean. Disabled by default.
136 setsebool -P allow_ptrace 1

142 allow_ypbind boolean. Disabled by default.
143 setsebool -P allow_ypbind 1
145 If you want to allow codnor domain to connect to the network using TCP,
149 you must turn on the condor_domain_can_network_connect boolean. Dis‐
150 abled by default.
151 setsebool -P condor_domain_can_network_connect 1
153 If you want to enable cluster mode for daemons, you must turn on the
157 daemons_enable_cluster_mode boolean. Disabled by default.
158 setsebool -P daemons_enable_cluster_mode 1
160 If you want to allow all domains to have the kernel load modules, you
164 must turn on the domain_kernel_load_modules boolean. Disabled by
165 default.
166 setsebool -P domain_kernel_load_modules 1
168 If you want to allow all domains to execute in fips_mode, you must turn
172 on the fips_mode boolean. Enabled by default.
173 setsebool -P fips_mode 1
175 If you want to enable reading of urandom for all domains, you must turn
179 on the global_ssp boolean. Disabled by default.
180 setsebool -P global_ssp 1
182 If you want to enable support for upstart as the init program, you must
186 turn on the init_upstart boolean. Enabled by default.
187 setsebool -P init_upstart 1
189 If you want to allow certain domains to map low memory in the kernel,
193 you must turn on the mmap_low_allowed boolean. Disabled by default.
194 setsebool -P mmap_low_allowed 1
196 If you want to allow confined applications to use nscd shared memory,
200 you must turn on the nscd_use_shm boolean. Enabled by default.
201 setsebool -P nscd_use_shm 1
203 If you want to boolean to determine whether the system permits loading
207 policy, setting enforcing mode, and changing boolean values. Set this

209 secure_mode_policyload boolean. Disabled by default.

223 The SELinux process type condor_master_t can manage files labeled with
224 the following file types. The paths listed are the default paths for
225 these file types. Note the processes UID still need to have DAC per‐
226 missions.
227 file_type
229 all files on the system
231
234 SELinux requires files to have an extended attribute to define the file
235 type.
236 You can see the context of a file using the -Z option to ls
238 Policy governs the access confined processes have to these files.
240 SELinux condor_master policy is very flexible allowing users to setup
241 their condor_master processes in as secure a method as possible.
242 The following file types are defined for condor_master:
244 condor_master_exec_t
248 - Set files with the condor_master_exec_t type, if you want to transi‐
250 tion an executable to the condor_master_t domain.
251 Note: File context can be temporarily modified with the chcon command.
255 If you want to permanently change the file context you need to use the
256 semanage fcontext command. This will modify the SELinux labeling data‐
257 base. You will need to use restorecon to apply the labels.
258
261 semanage fcontext can also be used to manipulate default file context
262 mappings.
263 semanage permissive can also be used to manipulate whether or not a
265 process type is permissive.
266 semanage module can also be used to enable/disable/install/remove pol‐
268 icy modules.
269 semanage boolean can also be used to manipulate the booleans
271 system-config-selinux is a GUI tool available to customize SELinux pol‐
274 icy settings.
