Description of problem: SELinux is preventing rpcbind 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 rpcbind 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: file_context_t, fonts_cache_t, fonts_t, ld_so_cache_t, ld_so_t, lib_t, locale_t, prelink_exec_t, rpcbind_exec_t, shell_exec_t, sssd_public_t, systemd_tmpfiles_exec_t, textrel_shlib_t. Then execute: restorecon -v '/etc/ld.so.cache' ***** Plugin catchall (1.44 confidence) suggests ************************** If you believe that rpcbind 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 'rpcbind' --raw | audit2allow -M my-rpcbind # semodule -X 300 -i my-rpcbind.pp Additional Information: Source Context system_u:system_r:rpcbind_t:s0 Target Context system_u:object_r:etc_t:s0 Target Objects /etc/ld.so.cache [ file ] Source rpcbind Source Path rpcbind Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages glibc-2.26-27.fc27.x86_64 glibc-2.26-27.fc27.i686 Policy RPM selinux-policy-3.13.1-283.32.fc27.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.16.5-200.fc27.x86_64 #1 SMP Fri Apr 27 19:05:44 UTC 2018 x86_64 x86_64 Alert Count 1 First Seen 2018-05-04 12:12:52 CEST Last Seen 2018-05-04 12:12:52 CEST Local ID 42fd9027-014d-453f-a509-520c3c927df5 Raw Audit Messages type=AVC msg=audit(1525428772.970:172): avc: denied { map } for pid=1054 comm="rpcbind" path="/etc/ld.so.cache" dev="dm-0" ino=918835 scontext=system_u:system_r:rpcbind_t:s0 tcontext=system_u:object_r:etc_t:s0 tclass=file permissive=0 Hash: rpcbind,rpcbind_t,etc_t,file,map Version-Release number of selected component: selinux-policy-3.13.1-283.32.fc27.noarch Additional info: component: selinux-policy reporter: libreport-2.9.3 hashmarkername: setroubleshoot kernel: 4.16.5-200.fc27.x86_64 type: libreport
