6 condor_startd_selinux - Security Enhanced Linux Policy for the con‐
7 dor_startd processes
8
10 Security-Enhanced Linux secures the condor_startd processes via flexi‐
11 ble mandatory access control.
12 The condor_startd processes execute with the condor_startd_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_startd_t
20
24 The condor_startd_t SELinux type can be entered via the con‐
25 dor_startd_exec_t file type.
26 The default entrypoint paths for the condor_startd_t domain are the
28 following:
29 /usr/sbin/condor_startd, /usr/sbin/condor_starter
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 condor_startd policy is very flexible allowing users to setup their
40 condor_startd processes in as secure a method as possible.
41 The following process types are defined for condor_startd:
43 condor_startd_t, condor_startd_ssh_t
45 Note: semanage permissive -a condor_startd_t can be used to make the
47 process type condor_startd_t permissive. SELinux does not deny access
48 to permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. con‐
54 dor_startd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run condor_startd with the
56 tightest access possible.
57 If you want to control the ability to mmap a low area of the address
61 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
62 the mmap_low_allowed boolean. Disabled by default.
63 setsebool -P mmap_low_allowed 1
65 If you want to disable kernel module loading, you must turn on the se‐
69 cure_mode_insmod boolean. Enabled by default.
70 setsebool -P secure_mode_insmod 1
72 If you want to allow unconfined executables to make their heap memory
76 executable. Doing this is a really bad idea. Probably indicates a
77 badly coded executable, but could indicate an attack. This executable
78 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
79 echeap boolean. Disabled by default.
80 setsebool -P selinuxuser_execheap 1
82 If you want to allow unconfined executables to make their stack exe‐
86 cutable. This should never, ever be necessary. Probably indicates a
87 badly coded executable, but could indicate an attack. This executable
88 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
89 stack boolean. Enabled by default.
90 setsebool -P selinuxuser_execstack 1

96 The SELinux process type condor_startd_t can manage files labeled with
97 the following file types. The paths listed are the default paths for
98 these file types. Note the processes UID still need to have DAC per‐
99 missions.
100 file_type
102 all files on the system
104
107 SELinux requires files to have an extended attribute to define the file
108 type.
109 You can see the context of a file using the -Z option to ls
111 Policy governs the access confined processes have to these files.
113 SELinux condor_startd policy is very flexible allowing users to setup
114 their condor_startd processes in as secure a method as possible.
115 STANDARD FILE CONTEXT
117 SELinux defines the file context types for the condor_startd, if you
119 wanted to store files with these types in a diffent paths, you need to
120 execute the semanage command to specify alternate labeling and then use
121 restorecon to put the labels on disk.
122 semanage fcontext -a -t condor_startd_tmpfs_t '/srv/mycon‐
124 dor_startd_content(/.*)?'
125 restorecon -R -v /srv/mycondor_startd_content
126 Note: SELinux often uses regular expressions to specify labels that
128 match multiple files.
129 The following file types are defined for condor_startd:
131 condor_startd_exec_t
135 - Set files with the condor_startd_exec_t type, if you want to transi‐
137 tion an executable to the condor_startd_t domain.
138 Paths:
141 /usr/sbin/condor_startd, /usr/sbin/condor_starter
142 condor_startd_tmp_t
145 - Set files with the condor_startd_tmp_t type, if you want to store
147 condor startd temporary files in the /tmp directories.
148 condor_startd_tmpfs_t
152 - Set files with the condor_startd_tmpfs_t type, if you want to store
154 condor startd files on a tmpfs file system.
155 Note: File context can be temporarily modified with the chcon command.
159 If you want to permanently change the file context you need to use the
160 semanage fcontext command. This will modify the SELinux labeling data‐
161 base. You will need to use restorecon to apply the labels.
162
165 semanage fcontext can also be used to manipulate default file context
166 mappings.
167 semanage permissive can also be used to manipulate whether or not a
169 process type is permissive.
170 semanage module can also be used to enable/disable/install/remove pol‐
172 icy modules.
173 semanage boolean can also be used to manipulate the booleans
175 system-config-selinux is a GUI tool available to customize SELinux pol‐
178 icy settings.
