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.

Comment 2 Alexander Bokovoy 2021-06-09 08:37:37 UTC 
Moving to selinux-policy.

On Fedora 34 I have this:

# sesearch --source sssd_t --target proc_t --allow 
allow domain file_type:blk_file map; [ domain_can_mmap_files ]:True
allow domain file_type:chr_file map; [ domain_can_mmap_files ]:True
allow domain file_type:file map; [ domain_can_mmap_files ]:True
allow domain file_type:lnk_file map; [ domain_can_mmap_files ]:True
allow domain proc_t:dir { getattr open search };
allow domain proc_t:filesystem getattr;
allow domain proc_t:lnk_file { getattr read };
allow kernel_system_state_reader proc_t:dir { ioctl lock read };
allow kernel_system_state_reader proc_t:file { getattr ioctl lock open read };

e.g. proc_t:filesystem getattr is allowed

On RHEL 8.5.0 I have this:

# sesearch --source sssd_t --target proc_t --allow
allow domain file_type:blk_file map; [ domain_can_mmap_files ]:True
allow domain file_type:chr_file map; [ domain_can_mmap_files ]:True
allow domain file_type:file map; [ domain_can_mmap_files ]:True
allow domain file_type:lnk_file map; [ domain_can_mmap_files ]:True
allow domain proc_t:dir { getattr open search };
allow domain proc_t:dir { getattr open search }; [ fips_mode ]:True
allow domain proc_t:dir { getattr open search }; [ fips_mode ]:True
allow domain proc_t:lnk_file { getattr read };
allow kernel_system_state_reader proc_t:dir { getattr ioctl lock open read search };
allow kernel_system_state_reader proc_t:file { getattr ioctl lock open read };
allow kernel_system_state_reader proc_t:lnk_file { getattr read };
allow sssd_t proc_t:dir { getattr open search };

e.g. proc_t:filesystem getattr is not allowed.
