Description of problem: SELinux is preventing dmidecode from 'map' accesses on the file /etc/ld.so.cache. ***** Plugin restorecon (94.8 confidence) suggests ************************ If you want to fix the label. /etc/ld.so.cache default label should be ld_so_cache_t. Then you can run restorecon. The access attempt may have been stopped due to insufficient permissions to access a parent directory in which case try to change the following command accordingly. Do # /sbin/restorecon -v /etc/ld.so.cache ***** Plugin catchall_labels (5.21 confidence) suggests ******************* If you want to allow dmidecode to have map access on the ld.so.cache file Then you need to change the label on /etc/ld.so.cache Do # semanage fcontext -a -t FILE_TYPE '/etc/ld.so.cache' where FILE_TYPE is one of the following: dmidecode_exec_t, fonts_cache_t, fonts_t, ld_so_cache_t, ld_so_t, lib_t, locale_t, prelink_exec_t, textrel_shlib_t. Then execute: restorecon -v '/etc/ld.so.cache' ***** Plugin catchall (1.44 confidence) suggests ************************** If you believe that dmidecode should be allowed map access on the ld.so.cache file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'dmidecode' --raw | audit2allow -M my-dmidecode # semodule -X 300 -i my-dmidecode.pp Additional Information: Source Context system_u:system_r:dmidecode_t:s0-s0:c0.c1023 Target Context system_u:object_r:etc_t:s0 Target Objects /etc/ld.so.cache [ file ] Source dmidecode Source Path dmidecode Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages glibc-2.26-26.fc27.x86_64 glibc-2.26-26.fc27.i686 Policy RPM selinux-policy-3.13.1-283.26.fc27.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.15.6-300.fc27.x86_64 #1 SMP Mon Feb 26 18:43:03 UTC 2018 x86_64 x86_64 Alert Count 1 First Seen 2018-03-12 16:01:35 EDT Last Seen 2018-03-12 16:01:35 EDT Local ID 2d9408e2-b5ef-413c-a6ac-167f8dfad2cc Raw Audit Messages type=AVC msg=audit(1520884895.405:196): avc: denied { map } for pid=1884 comm="dmidecode" path="/etc/ld.so.cache" dev="dm-1" ino=1050448 scontext=system_u:system_r:dmidecode_t:s0-s0:c0.c1023 tcontext=system_u:object_r:etc_t:s0 tclass=file permissive=0 Hash: dmidecode,dmidecode_t,etc_t,file,map Version-Release number of selected component: selinux-policy-3.13.1-283.26.fc27.noarch Additional info: component: selinux-policy reporter: libreport-2.9.3 hashmarkername: setroubleshoot kernel: 4.15.6-300.fc27.x86_64 type: libreport
