Greetings! After three months in /testing, the PAM merge into the main tree is now complete. When updating, be sure to install the new pam, cracklib, and libpwquality packages or you may find yourself locked out of your machine. Otherwise, these changes should be completely transparent and you shouldn't notice any obvious operational differences. Be careful if you make any changes in /etc/pam.d/ - leaving an extra console logged in while testing PAM config changes is a recommended standard procedure. Thanks again to Robby Workman, Vincent Batts, Phantom X, and ivandi for help implementing this. It's not done yet and there will be more fine-tuning of the config files, but now we can move on to build some other updates. Enjoy! a/cracklib-2.9.7-x86_64-1.txz: Added. a/kernel-firmware-20200517_f8d32e4-noarch-1.txz: Upgraded. a/libcgroup-0.41-x86_64-7.txz: Rebuilt.

+Subject: [PATCH] pam_unix: Report unusable hashes found by checksalt to
+ syslog.
+
+libxcrypt can be build-time configured to support (or not support)
+various hashing methods. Future versions will also have support for
+runtime configuration by the system's vendor and/or administrator.
+
+For that reason adminstrator should be notified by pam if users cannot
+log into their account anymore because of such a change in the system's
+configuration of libxcrypt.
+
+Also check for malformed hashes, like descrypt hashes starting with
+"$2...", which might have been generated by unsafe base64 encoding
+functions as used in glibc <= 2.16.
+Such hashes are likely to be rejected by many recent implementations
+of libcrypt.
+
+* modules/pam_unix/passverify.c (verify_pwd_hash): Report unusable
+hashes found by checksalt to syslog.
