RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

After installing ibus-table-chinese-yong, rpm verify shows an error:

# rpm -V ibus-table-chinese-yong
..5....T.    /usr/share/ibus-table/tables/yong.db

This signals that the file was modified (different md5) compared to the packaged one, which is a warning that a malicious user might have tampered with it.

However in this case, the file seems to be created with

postinstall scriptlet (using /bin/sh):
ibus-table-createdb -i -n /usr/share/ibus-table/tables/yong.db

so please consider not installing it and marking it as %ghost in the spec file, indicating that the package owns it, but not included by default, to be created during runtime.

(See ie. how the rpm package itself uses %ghost on its own rpmdb.)


Version-Release number of selected component (if applicable):
ibus-table-chinese-yong-1.8.3-9.el9

The yong.db file is created when build the package, and only slightly modified when install the package.

I think I will use the following line in the spec file.

%verify(not size md5 mtime) %{ibus_tables_dir}/yong.db

I think the databases should not be indexed in the post install scripts at all. 

If any indexing is necessary, it should better be done at build time.
Currently no indexing is done anyway, i.e. the “indexing” currently done in post install scripts achieves nothing apart from changing the time stamps of the files.
