6 rpm_script_selinux - Security Enhanced Linux Policy for the rpm_script
7 processes
8
10 Security-Enhanced Linux secures the rpm_script processes via flexible
11 mandatory access control.
12 The rpm_script processes execute with the rpm_script_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep rpm_script_t
20
24 The rpm_script_t SELinux type can be entered via the usr_t, ldcon‐
25 fig_exec_t, bin_t, shell_exec_t file types.
26 The default entrypoint paths for the rpm_script_t domain are the fol‐
28 lowing:
29 All executeables with the default executable label, usually stored in
31 /usr/bin and /usr/sbin. /opt/.*, /usr/.*, /emul/.*, /export(/.*)?,
32 /ostree(/.*)?, /usr/doc(/.*)?/lib(/.*)?, /usr/inclu.e(/.*)?,
33 /usr/share/rpm(/.*)?, /usr/share/doc(/.*)?/README.*, /usr/lib/mod‐
34 ules(/.*)/vmlinuz, /usr/lib/modules(/.*)/initramfs.img, /usr/lib/sysim‐
35 age(/.*)?, /usr/lib/ostree-boot(/.*)?, /opt, /usr, /emul, /sbin/sln,
36 /usr/sbin/sln, /sbin/ldconfig, /usr/sbin/ldconfig, /bin/d?ash,
37 /bin/ksh.*, /bin/zsh.*, /usr/bin/d?ash, /usr/bin/ksh.*, /usr/bin/zsh.*,
38 /bin/esh, /bin/bash, /bin/fish, /bin/mksh, /bin/sash, /bin/tcsh,
39 /bin/yash, /bin/bash2, /usr/bin/esh, /sbin/nologin, /usr/bin/bash,

47 SELinux defines process types (domains) for each process running on the
48 system
49 You can see the context of a process using the -Z option to ps
51 Policy governs the access confined processes have to files. SELinux
53 rpm_script policy is very flexible allowing users to setup their
54 rpm_script processes in as secure a method as possible.
55 The following process types are defined for rpm_script:
57 rpm_script_t
59 Note: semanage permissive -a rpm_script_t can be used to make the
61 process type rpm_script_t permissive. SELinux does not deny access to
62 permissive process types, but the AVC (SELinux denials) messages are
63 still generated.
64
67 SELinux policy is customizable based on least access required.
68 rpm_script policy is extremely flexible and has several booleans that
69 allow you to manipulate the policy and run rpm_script with the tightest
70 access possible.
71 If you want to allow users to resolve user passwd entries directly from
75 ldap rather then using a sssd server, you must turn on the authlo‐
76 gin_nsswitch_use_ldap boolean. Disabled by default.
77 setsebool -P authlogin_nsswitch_use_ldap 1
79 If you want to deny user domains applications to map a memory region as
83 both executable and writable, this is dangerous and the executable
84 should be reported in bugzilla, you must turn on the deny_execmem bool‐
85 ean. Enabled by default.
86 setsebool -P deny_execmem 1
88 If you want to allow all domains to execute in fips_mode, you must turn
92 on the fips_mode boolean. Enabled by default.
93 setsebool -P fips_mode 1
95 If you want to allow confined applications to run with kerberos, you
99 must turn on the kerberos_enabled boolean. Disabled by default.
100 setsebool -P kerberos_enabled 1
102 If you want to control the ability to mmap a low area of the address
106 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
107 the mmap_low_allowed boolean. Disabled by default.
108 setsebool -P mmap_low_allowed 1
110 If you want to allow system to run with NIS, you must turn on the
114 nis_enabled boolean. Disabled by default.
115 setsebool -P nis_enabled 1
117 If you want to allow confined applications to use nscd shared memory,
121 you must turn on the nscd_use_shm boolean. Disabled by default.
122 setsebool -P nscd_use_shm 1
124 If you want to disable kernel module loading, you must turn on the
128 secure_mode_insmod boolean. Enabled by default.
129 setsebool -P secure_mode_insmod 1
131 If you want to allow unconfined executables to make their heap memory
135 executable. Doing this is a really bad idea. Probably indicates a
136 badly coded executable, but could indicate an attack. This executable
137 should be reported in bugzilla, you must turn on the selin‐
138 uxuser_execheap boolean. Disabled by default.
139 setsebool -P selinuxuser_execheap 1
141 If you want to allow unconfined executables to make their stack exe‐
145 cutable. This should never, ever be necessary. Probably indicates a
146 badly coded executable, but could indicate an attack. This executable
147 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
148 stack boolean. Disabled by default.
149 setsebool -P selinuxuser_execstack 1

155 The SELinux process type rpm_script_t can manage files labeled with the
156 following file types. The paths listed are the default paths for these
157 file types. Note the processes UID still need to have DAC permissions.
158 file_type
160 all files on the system
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.
