+# Extra package: lkrg
+
+## EL8 and EL9
+
+- Version `lkrg-0.9.7-4.el9_2.security`
+- Based on upstream version `0.9.7`
+
+### Package summary
+
+LKRG, or Linux Kernel Runtime Guard, is a kernel module that performs runtime integrity checking of the Linux kernel and detection of security vulnerability exploits against the kernel.
+
+More information is available on the [LKRG homepage](https://lkrg.org) and in the documentation files included in the package.
+
+### Usage in Rocky Linux
+
+Due to EL's kABI stability and the `weak-modules` mechanism, which this package uses, the same binary package of LKRG works across different kernel revisions/builds within the same EL minor release (e.g., 9.2). Once there's a new minor release (e.g., 9.2 is upgraded to 9.3), we'll provide a new build of LKRG accordingly.
+
+Installing the package does not automatically start LKRG nor enable it to start on system bootup. To start LKRG please use:
+
+```
+systemctl start lkrg
+```
+
+To enable LKRG on bootup please use:
+
+```
+systemctl enable lkrg
+```
+
+### Testing and recovery
+
+Although the current package passed our own testing (on 8.8 and 9.2), we recommend that you only enable LKRG to start on system bootup after you've tested it for a while to ensure its compatibility with your system. If you nevertheless run into a boot time issue with LKRG later, you can disable it with the `nolkrg` kernel command-line option.
+
+### Change log
+
+```
+* Wed Nov 08 2023 Solar Designer <solar@openwall.com> 0.9.7-4
+- Add a couple of upstream patches, most notably to fix kINT false positives on
+EL 8.8.
+
+* Tue Oct 24 2023 Solar Designer <solar@openwall.com> 0.9.7-3
+- Use weak-modules if available so that on RHEL and its rebuilds the same LKRG
+  package build works across different kABI-compatible kernel revisions/builds
+- Drop 32-bit x86 from ExclusiveArch since recent RHEL lacks such kernel-devel
+
+* Thu Sep 14 2023 Solar Designer <solar@openwall.com> 0.9.7-2
+- Use kernel build directory corresponding to the kernel-devel package, not to
+the currently running kernel
+- "BuildRequires: kernel" for the /lib/modules/* directory
+- "BuildRequires: elfutils-libelf-devel" to support CONFIG_UNWINDER_ORC=y
+
+* Thu Sep 14 2023 Solar Designer <solar@openwall.com> 0.9.7-1
+- Wrote this rough RPM spec file for Red Hat'ish distros, seems to work fine on
+RHEL 7, 8, 9 rebuilds, but is only reliable when there's exactly one
+kernel-devel package installed at build time and it exactly matches the target
+kernel version.

+# Extra package: passwdqc

+- Version `2.0.3-2.el9_2.security`
+- Based on upstream version `2.0.3-2` as packaged in Fedora
+
+### Package summary
+
+`passwdqc` is a password/passphrase strength checking and policy enforcement toolset, including a PAM module (`pam_passwdqc`), command-line programs (`pwqcheck`, `pwqfilter`, and `pwqgen`), and a library (`libpasswdqc`).
+
+More information is available on the [passwdqc homepage](https://www.openwall.com/passwdqc/) and in the documentation files (man pages and a README) included in the sub-packages below.
+
+### Usage in Rocky Linux
+
+There are 4 sub-packages:
+
+#### pam_passwdqc
+
+`pam_passwdqc` is a PAM module that is normally invoked on password changes by programs such as `passwd(1)`. It is capable of checking password or passphrase strength, enforcing a policy, and offering randomly-generated passphrases, with all of these features being optional and easily (re-)configurable.
+
+Merely installing this sub-package does not yet configure the system to use the PAM module. To do so, please edit PAM configuration files e.g. like [shown here](https://github.com/openwall/passwdqc/issues/19#issuecomment-1140262371).
+
+#### passwdqc-utils
+
+`pwqcheck` and `pwqgen` are standalone password/passphrase strength checking and random passphrase generator programs, respectively, which are usable from scripts.
+
+The `pwqfilter` program searches, creates, or updates binary passphrase filter files, which can also be used with `pwqcheck` and `pam_passwdqc`. This can be used for checking of user-provided passwords against existing data breaches, which is recommended in the current NIST guidance, specifically in publication 800-63B sections 5.1.1.2 and A.3. Paid pre-generated filter files are available from Openwall at the project homepage above, but with this tool you can also generate your own.
+
+#### libpasswdqc
+
+`libpasswdqc` is the underlying library, which may also be used from third-party programs.
+
+#### passwdqc
+
+`passwdqc` is a meta sub-package that installs (via dependencies) all 3 actual sub-packages above.
