From 7809f29b68e17a455478990ae9b22728381a126b Mon Sep 17 00:00:00 2001

Subject: [PATCH] semodule,libsemanage: move module hashing into libsemanage
The main goal of this move is to have the SHA-256 implementation under
libsemanage, since upcoming patches will make use of SHA-256 for a
different (but similar) purpose in libsemanage. Having the hashing code
in libsemanage will reduce code duplication and allow for easier hash
algorithm upgrade in the future.
Note that libselinux currently also contains a hash function
implementation (for yet another different purpose). This patch doesn't
make any effort to address that duplicity yet.
This patch also changes the format of the hash string printed by
semodule to include the name of the hash. The intent is to avoid
ambiguity and potential collisions when the algorithm is potentially
changed in the future.

Subject: [PATCH] semodule: add command-line option to detect module changes
Add a new command-line option "--rebuild-if-modules-changed" to control
the newly introduced check_ext_changes libsemanage flag.
For example, running `semodule --rebuild-if-modules-changed` will ensure
that any externally added/removed modules (e.g. by an RPM transaction)
are reflected in the compiled policy, while skipping the most expensive
part of the rebuild if no module change was deteceted since the last
libsemanage transaction.
