6 rtas_errd_selinux - Security Enhanced Linux Policy for the rtas_errd
7 processes
8
10 Security-Enhanced Linux secures the rtas_errd processes via flexible
11 mandatory access control.
12 The rtas_errd processes execute with the rtas_errd_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 rtas_errd_t
20
24 The rtas_errd_t SELinux type can be entered via the rtas_errd_exec_t
25 file type.
26 The default entrypoint paths for the rtas_errd_t domain are the follow‐
28 ing:
29 /usr/sbin/rtas_errd, /usr/libexec/ppc64-diag/rtas_errd
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 rtas_errd policy is very flexible allowing users to setup their
40 rtas_errd processes in as secure a method as possible.
41 The following process types are defined for rtas_errd:
43 rtas_errd_t
45 Note: semanage permissive -a rtas_errd_t can be used to make the
47 process type rtas_errd_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.
54 rtas_errd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run rtas_errd with the tightest
56 access 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 allow all domains to execute in fips_mode, you must turn
78 on the fips_mode boolean. Enabled by default.
79 setsebool -P fips_mode 1
81 If you want to allow confined applications to run with kerberos, you
85 must turn on the kerberos_enabled boolean. Enabled by default.
86 setsebool -P kerberos_enabled 1
88 If you want to control the ability to mmap a low area of the address
92 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
93 the mmap_low_allowed boolean. Disabled by default.
94 setsebool -P mmap_low_allowed 1
96 If you want to allow system to run with NIS, you must turn on the
100 nis_enabled boolean. Disabled by default.
101 setsebool -P nis_enabled 1
103 If you want to allow confined applications to use nscd shared memory,
107 you must turn on the nscd_use_shm boolean. Disabled by default.
108 setsebool -P nscd_use_shm 1
110 If you want to disable kernel module loading, you must turn on the
114 secure_mode_insmod boolean. Enabled by default.
115 setsebool -P secure_mode_insmod 1
117 If you want to allow unconfined executables to make their heap memory
121 executable. Doing this is a really bad idea. Probably indicates a
122 badly coded executable, but could indicate an attack. This executable
123 should be reported in bugzilla, you must turn on the selin‐
124 uxuser_execheap boolean. Disabled by default.
125 setsebool -P selinuxuser_execheap 1
127 If you want to allow unconfined executables to make their stack exe‐
131 cutable. This should never, ever be necessary. Probably indicates a
132 badly coded executable, but could indicate an attack. This executable
133 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
134 stack boolean. Enabled by default.
135 setsebool -P selinuxuser_execstack 1
137
141 The SELinux process type rtas_errd_t can manage files labeled with the
142 following file types. The paths listed are the default paths for these
143 file types. Note the processes UID still need to have DAC permissions.
144 file_type
146 all files on the system
148
151 SELinux requires files to have an extended attribute to define the file
152 type.
153 You can see the context of a file using the -Z option to ls
155 Policy governs the access confined processes have to these files.
157 SELinux rtas_errd policy is very flexible allowing users to setup their
158 rtas_errd processes in as secure a method as possible.
159 STANDARD FILE CONTEXT
161 SELinux defines the file context types for the rtas_errd, if you wanted
163 to store files with these types in a diffent paths, you need to execute
164 the semanage command to sepecify alternate labeling and then use
165 restorecon to put the labels on disk.
166 semanage fcontext -a -t rtas_errd_tmpfs_t '/srv/myrtas_errd_con‐
168 tent(/.*)?'
169 restorecon -R -v /srv/myrtas_errd_content
170 Note: SELinux often uses regular expressions to specify labels that
172 match multiple files.
173 The following file types are defined for rtas_errd:
175 rtas_errd_exec_t
179 - Set files with the rtas_errd_exec_t type, if you want to transition
181 an executable to the rtas_errd_t domain.
182 Paths:
185 /usr/sbin/rtas_errd, /usr/libexec/ppc64-diag/rtas_errd
186 rtas_errd_log_t
189 - Set files with the rtas_errd_log_t type, if you want to treat the
191 data as rtas errd log data, usually stored under the /var/log direc‐
192 tory.
193 Paths:
196 /var/log/platform.*, /var/log/rtas_errd.*, /var/log/epow_status.*
197 rtas_errd_tmp_t
200 - Set files with the rtas_errd_tmp_t type, if you want to store rtas
202 errd temporary files in the /tmp directories.
203 rtas_errd_tmpfs_t
207 - Set files with the rtas_errd_tmpfs_t type, if you want to store rtas
209 errd files on a tmpfs file system.
210 rtas_errd_unit_file_t
214 - Set files with the rtas_errd_unit_file_t type, if you want to treat
216 the files as rtas errd unit content.
217 rtas_errd_var_lock_t
221 - Set files with the rtas_errd_var_lock_t type, if you want to treat
223 the files as rtas errd var lock data, stored under the /var/lock direc‐
224 tory
225 Paths:
228 /var/lock/.*librtas, /var/lock/subsys/rtas_errd
229 rtas_errd_var_run_t
232 - Set files with the rtas_errd_var_run_t type, if you want to store the
234 rtas errd files under the /run or /var/run directory.
235 Note: File context can be temporarily modified with the chcon command.
239 If you want to permanently change the file context you need to use the
240 semanage fcontext command. This will modify the SELinux labeling data‐
241 base. You will need to use restorecon to apply the labels.
242
245 semanage fcontext can also be used to manipulate default file context
246 mappings.
247 semanage permissive can also be used to manipulate whether or not a
249 process type is permissive.
250 semanage module can also be used to enable/disable/install/remove pol‐
252 icy modules.
253 semanage boolean can also be used to manipulate the booleans
255 system-config-selinux is a GUI tool available to customize SELinux pol‐
258 icy settings.
