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 file_type, unla‐
25 beled_t, proc_type, filesystem_type, sosreport_exec_t, mtrr_device_t,
26 sysctl_type file types.
27 The default entrypoint paths for the sosreport_t domain are the follow‐
29 ing:
30 all files on the system, /usr/sbin/sosreport, /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 sosreport policy is very flexible allowing users to setup their sosre‐
41 port processes in as secure a method as possible.
42 The following process types are defined for sosreport:
44 sosreport_t
46 Note: semanage permissive -a sosreport_t can be used to make the
48 process type sosreport_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. sosre‐
55 port policy is extremely flexible and has several booleans that allow
56 you to manipulate the policy and run sosreport with the tightest access
57 possible.
58 If you want to allow all domains to use other domains file descriptors,
62 you must turn on the allow_domain_fd_use boolean. Enabled by default.
63 setsebool -P allow_domain_fd_use 1
65 If you want to allow unconfined executables to make their heap memory
69 executable. Doing this is a really bad idea. Probably indicates a
70 badly coded executable, but could indicate an attack. This executable
71 should be reported in bugzilla, you must turn on the allow_execheap
72 boolean. Disabled by default.
73 setsebool -P allow_execheap 1
75 If you want to allow unconfined executables to map a memory region as
79 both executable and writable, this is dangerous and the executable
80 should be reported in bugzilla), you must turn on the allow_execmem
81 boolean. Enabled by default.
82 setsebool -P allow_execmem 1
84 If you want to allow all unconfined executables to use libraries
88 requiring text relocation that are not labeled textrel_shlib_t), you
89 must turn on the allow_execmod boolean. Enabled by default.
90 setsebool -P allow_execmod 1
92 If you want to allow unconfined executables to make their stack exe‐
96 cutable. This should never, ever be necessary. Probably indicates a
97 badly coded executable, but could indicate an attack. This executable
98 should be reported in bugzilla), you must turn on the allow_execstack
99 boolean. Enabled by default.
100 setsebool -P allow_execstack 1
102 If you want to allow confined applications to run with kerberos, you
106 must turn on the allow_kerberos boolean. Enabled by default.
107 setsebool -P allow_kerberos 1
109 If you want to allow sysadm to debug or ptrace all processes, you must
113 turn on the allow_ptrace boolean. Disabled by default.
114 setsebool -P allow_ptrace 1
116 If you want to allow system to run with NIS, you must turn on the
120 allow_ypbind boolean. Disabled by default.
121 setsebool -P allow_ypbind 1
123 If you want to allow all domains to have the kernel load modules, you
127 must turn on the domain_kernel_load_modules boolean. Disabled by
128 default.
129 setsebool -P domain_kernel_load_modules 1
131 If you want to allow all domains to execute in fips_mode, you must turn
135 on the fips_mode boolean. Enabled by default.
136 setsebool -P fips_mode 1
138 If you want to enable reading of urandom for all domains, you must turn
142 on the global_ssp boolean. Disabled by default.
143 setsebool -P global_ssp 1
145 If you want to allow certain domains to map low memory in the kernel,
149 you must turn on the mmap_low_allowed boolean. Disabled by default.
150 setsebool -P mmap_low_allowed 1
152 If you want to allow confined applications to use nscd shared memory,
156 you must turn on the nscd_use_shm boolean. Enabled by default.
157 setsebool -P nscd_use_shm 1
159 If you want to boolean to determine whether the system permits loading
163 policy, setting enforcing mode, and changing boolean values. Set this
164 to true and you have to reboot to set it back, you must turn on the
165 secure_mode_policyload boolean. Disabled by default.
166 setsebool -P secure_mode_policyload 1
168 If you want to support X userspace object manager, you must turn on the
172 xserver_object_manager boolean. Disabled by default.
173 setsebool -P xserver_object_manager 1
175
179 The SELinux process type sosreport_t can manage files labeled with the
180 following file types. The paths listed are the default paths for these
181 file types. Note the processes UID still need to have DAC permissions.
182 file_type
184 all files on the system
186
189 SELinux requires files to have an extended attribute to define the file
190 type.
191 You can see the context of a file using the -Z option to ls
193 Policy governs the access confined processes have to these files.
195 SELinux sosreport policy is very flexible allowing users to setup their
196 sosreport processes in as secure a method as possible.
197 STANDARD FILE CONTEXT
199 SELinux defines the file context types for the sosreport, if you wanted
201 to store files with these types in a diffent paths, you need to execute
202 the semanage command to sepecify alternate labeling and then use
203 restorecon to put the labels on disk.
204 semanage fcontext -a -t sosreport_tmpfs_t '/srv/mysosreport_con‐
206 tent(/.*)?'
207 restorecon -R -v /srv/mysosreport_content
208 Note: SELinux often uses regular expressions to specify labels that
210 match multiple files.
211 The following file types are defined for sosreport:
213 sosreport_exec_t
217 - Set files with the sosreport_exec_t type, if you want to transition
219 an executable to the sosreport_t domain.
220 sosreport_tmp_t
224 - Set files with the sosreport_tmp_t type, if you want to store sosre‐
226 port temporary files in the /tmp directories.
227 sosreport_tmpfs_t
231 - Set files with the sosreport_tmpfs_t type, if you want to store sos‐
233 report files on a tmpfs file system.
234 Note: File context can be temporarily modified with the chcon command.
238 If you want to permanently change the file context you need to use the
239 semanage fcontext command. This will modify the SELinux labeling data‐
240 base. You will need to use restorecon to apply the labels.
241
244 semanage fcontext can also be used to manipulate default file context
245 mappings.
246 semanage permissive can also be used to manipulate whether or not a
248 process type is permissive.
249 semanage module can also be used to enable/disable/install/remove pol‐
251 icy modules.
252 semanage boolean can also be used to manipulate the booleans
254 system-config-selinux is a GUI tool available to customize SELinux pol‐
257 icy settings.
