6 sosreport_selinux - Security Enhanced Linux Policy for the sosreport
7 processes
8
10 Security-Enhanced Linux secures the sosreport processes via flexible
11 mandatory access control.
12 The sosreport processes execute with the sosreport_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 sosreport_t
20
24 The sosreport_t SELinux type can be entered via the sosreport_exec_t
25 file type.
26 The default entrypoint paths for the sosreport_t domain are the follow‐
28 ing:
29 /usr/sbin/sosreport
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 sosreport policy is very flexible allowing users to setup their sosre‐
40 port processes in as secure a method as possible.
41 The following process types are defined for sosreport:
43 sosreport_t
45 Note: semanage permissive -a sosreport_t can be used to make the
47 process type sosreport_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. sosre‐
54 port policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run sosreport with the tightest access
56 possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 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.
72 setsebool -P deny_execmem 1
74 If you want to deny any process from ptracing or debugging any other
78 processes, you must turn on the deny_ptrace boolean. Enabled by
79 default.
80 setsebool -P deny_ptrace 1
82 If you want to allow any process to mmap any file on system with
86 attribute file_type, you must turn on the domain_can_mmap_files bool‐
87 ean. Enabled by default.
88 setsebool -P domain_can_mmap_files 1
90 If you want to allow all domains write to kmsg_device, while kernel is
94 executed with systemd.log_target=kmsg parameter, you must turn on the
95 domain_can_write_kmsg boolean. Disabled by default.
96 setsebool -P domain_can_write_kmsg 1
98 If you want to allow all domains to use other domains file descriptors,
102 you must turn on the domain_fd_use boolean. Enabled by default.
103 setsebool -P domain_fd_use 1
105 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.
111 setsebool -P domain_kernel_load_modules 1
113 If you want to allow all domains to execute in fips_mode, you must turn
117 on the fips_mode boolean. Enabled by default.
118 setsebool -P fips_mode 1
120 If you want to enable reading of urandom for all domains, you must turn
124 on the global_ssp boolean. Disabled by default.
125 setsebool -P global_ssp 1
127 If you want to allow confined applications to run with kerberos, you
131 must turn on the kerberos_enabled boolean. Enabled by default.
132 setsebool -P kerberos_enabled 1
134 If you want to control the ability to mmap a low area of the address
138 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
139 the mmap_low_allowed boolean. Disabled by default.
140 setsebool -P mmap_low_allowed 1
142 If you want to allow system to run with NIS, you must turn on the
146 nis_enabled boolean. Disabled by default.
147 setsebool -P nis_enabled 1
149 If you want to allow confined applications to use nscd shared memory,
153 you must turn on the nscd_use_shm boolean. Disabled by default.
154 setsebool -P nscd_use_shm 1
156 If you want to disable kernel module loading, you must turn on the
160 secure_mode_insmod boolean. Enabled by default.
161 setsebool -P secure_mode_insmod 1
163 If you want to boolean to determine whether the system permits loading
167 policy, setting enforcing mode, and changing boolean values. Set this
168 to true and you have to reboot to set it back, you must turn on the
169 secure_mode_policyload boolean. Enabled by default.
170 setsebool -P secure_mode_policyload 1
172 If you want to allow unconfined executables to make their heap memory
176 executable. Doing this is a really bad idea. Probably indicates a
177 badly coded executable, but could indicate an attack. This executable
178 should be reported in bugzilla, you must turn on the selin‐
179 uxuser_execheap boolean. Disabled by default.
180 setsebool -P selinuxuser_execheap 1
182 If you want to allow all unconfined executables to use libraries
186 requiring text relocation that are not labeled textrel_shlib_t, you
187 must turn on the selinuxuser_execmod boolean. Enabled by default.
188 setsebool -P selinuxuser_execmod 1
190 If you want to allow unconfined executables to make their stack exe‐
194 cutable. This should never, ever be necessary. Probably indicates a
195 badly coded executable, but could indicate an attack. This executable
196 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
197 stack boolean. Enabled by default.
198 setsebool -P selinuxuser_execstack 1
200 If you want to support NFS home directories, you must turn on the
204 use_nfs_home_dirs boolean. Disabled by default.
205 setsebool -P use_nfs_home_dirs 1

211 use_samba_home_dirs boolean. Disabled by default.
212 setsebool -P use_samba_home_dirs 1
214 If you want to support X userspace object manager, you must turn on the
218 xserver_object_manager boolean. Enabled by default.
219 setsebool -P xserver_object_manager 1
221
225 The SELinux process type sosreport_t can manage files labeled with the
226 following file types. The paths listed are the default paths for these
227 file types. Note the processes UID still need to have DAC permissions.
228 file_type
230 all files on the system
232
235 SELinux requires files to have an extended attribute to define the file
236 type.
237 You can see the context of a file using the -Z option to ls
239 Policy governs the access confined processes have to these files.
241 SELinux sosreport policy is very flexible allowing users to setup their
242 sosreport processes in as secure a method as possible.
243 STANDARD FILE CONTEXT
245 SELinux defines the file context types for the sosreport, if you wanted
247 to store files with these types in a diffent paths, you need to execute
248 the semanage command to sepecify alternate labeling and then use
249 restorecon to put the labels on disk.
250 semanage fcontext -a -t sosreport_var_run_t '/srv/mysosreport_con‐
252 tent(/.*)?'
253 restorecon -R -v /srv/mysosreport_content
254 Note: SELinux often uses regular expressions to specify labels that
256 match multiple files.
257 The following file types are defined for sosreport:
259 sosreport_exec_t
263 - Set files with the sosreport_exec_t type, if you want to transition
265 an executable to the sosreport_t domain.
266 sosreport_tmp_t
270 - Set files with the sosreport_tmp_t type, if you want to store sosre‐
272 port temporary files in the /tmp directories.
273 sosreport_tmpfs_t
277 - Set files with the sosreport_tmpfs_t type, if you want to store sos‐
279 report files on a tmpfs file system.
280 sosreport_var_run_t
284 - Set files with the sosreport_var_run_t type, if you want to store the
286 sosreport files under the /run or /var/run directory.
287 Note: File context can be temporarily modified with the chcon command.
291 If you want to permanently change the file context you need to use the
292 semanage fcontext command. This will modify the SELinux labeling data‐
293 base. You will need to use restorecon to apply the labels.
294
297 semanage fcontext can also be used to manipulate default file context
298 mappings.
299 semanage permissive can also be used to manipulate whether or not a
301 process type is permissive.
302 semanage module can also be used to enable/disable/install/remove pol‐
304 icy modules.
305 semanage boolean can also be used to manipulate the booleans
307 system-config-selinux is a GUI tool available to customize SELinux pol‐
310 icy settings.
