Subject: Regression in selabel_lookup after "rework selabel_file database"
Date: Wed, 16 Apr 2025 22:01:35 +0200	[thread overview]
Message-ID: <878qnzzxi8.fsf@redhat.com> (raw)

Hi,

we have a report [1] that in specific cases local fcontext modifications
are not considered or correctly resolved in `selabel_lookup`:

    [root@default-0 selinux]# matchpathcon /usr/bin/cloud-init
    /usr/bin/cloud-init     system_u:object_r:cloud_init_exec_t:s0
    [root@default-0 selinux]# semanage fcontext -a -t bin_t /usr/bin/cloud-init
    [root@default-0 selinux]# semanage fcontext -l -C
    SELinux fcontext                                   type               Context
    
    /usr/bin/cloud-init                                all files          system_u:object_r:bin_t:s0 
    [root@default-0 selinux]# matchpathcon /usr/bin/cloud-init
    /usr/bin/cloud-init     system_u:object_r:cloud_init_exec_t:s0


The bad commit seems to be 92306daf5219e73f6 ("libselinux: rework selabel_file(5) database")

Please take a look.
