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 Ladar Levison 2020-10-28 14:46:31 UTC
The selinux-targeted-policy for vnstat needs additional permissions. Specifically:

module my-vnstatd 1.0;

require {
	type vnstatd_var_lib_t;
	type init_t;
	class dir { mounton read setattr };
}

#============= init_t ==============
allow init_t vnstatd_var_lib_t:dir mounton;
allow init_t vnstatd_var_lib_t:dir { read setattr };

Comment 1 Zdenek Pytela 2020-11-06 13:12:51 UTC
Hi,

all of these permissions are allowed in the current selinux-policy version in RHEL 8.3

# sesearch -A -s init_t -t vnstatd_var_lib_t -c dir
allow init_t file_type:dir { getattr ioctl lock open read relabelfrom relabelto search };
allow init_t non_security_file_type:dir { create getattr }; [ init_create_dirs ]:True
allow init_t non_security_file_type:dir { mounton setattr write }; [ init_create_dirs ]:True
allow init_t non_security_file_type:dir { read setattr }; [ init_create_dirs ]:True
