Description of problem: Simple upgrade of my Fedora 30 box. This box has been continuously upgraded for 5 or more years so there may be cruft lying around. SELinux is preventing grub2-set-bootf from 'write' accesses on the directory /boot/grub2. ***** Plugin kernel_modules (91.4 confidence) suggests ******************** If you do not think grub2-set-bootf should try write access on grub2. Then you may be under attack by a hacker, since confined applications should not need this access. Do contact your security administrator and report this issue. ***** Plugin catchall (9.59 confidence) suggests ************************** If you believe that grub2-set-bootf should be allowed write access on the grub2 directory 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 'grub2-set-bootf' --raw | audit2allow -M my-grub2setbootf # semodule -X 300 -i my-grub2setbootf.pp Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:object_r:boot_t:s0 Target Objects /boot/grub2 [ dir ] Source grub2-set-bootf Source Path grub2-set-bootf Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages grub2-common-2.02-88.fc30.noarch Policy RPM selinux-policy-3.14.3-57.fc30.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 5.5.9-100.fc30.x86_64 #1 SMP Thu Mar 12 14:15:32 UTC 2020 x86_64 x86_64 Alert Count 2 First Seen 2020-04-08 10:24:30 EDT Last Seen 2020-04-08 10:24:53 EDT Local ID 510d453a-7fcd-46e5-9973-aa7db603acba Raw Audit Messages type=AVC msg=audit(1586355893.738:357): avc: denied { write } for pid=9180 comm="grub2-set-bootf" name="grub2" dev="dm-3" ino=1316974 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:boot_t:s0 tclass=dir permissive=0 Hash: grub2-set-bootf,xdm_t,boot_t,dir,write Version-Release number of selected component: selinux-policy-3.14.3-57.fc30.noarch Additional info: component: selinux-policy reporter: libreport-2.12.0 hashmarkername: setroubleshoot kernel: 5.5.10-100.fc30.x86_64 type: libreport

This message is a reminder that Fedora 30 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 30 on 2020-05-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '30'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 30 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
