Subject: [PATCH] libsemanage: always write kernel policy when
|
|
check_ext_changes is specified
|
|
Content-type: text/plain
|
|
|
|
For the use case of rebuilding the policy after package updates, we need
|
|
the check_ext_changes operation to always do at least the do_write_kernel
|
|
step, because the various semanage dbs may have also changed content
|
|
relative to the current binary policy. As this step is itself relatively
|
|
fast, we can do it unconditionally.
|
|
|
|
Fixes: 286a679fadc4 ("libsemanage: optionally rebuild policy when modules are changed externally")
