Why I did it

New security feature for enforcing strong passwords when login or changing passwords of existing users into the switch.

How I did it

By using mainly Linux package named pam-cracklib that support the enforcement of user passwords, the daemon named hostcfgd, will support add/modify password policies that enforce and strengthen the user passwords.

How to verify it

Manually Verification-

  1. Enable the feature, using the new sonic-cli command passw-hardening or manually add the password hardening table like shown in HLD by using redis-cli command

  2. Change password policies manually like in step 1.
    Notes:
    password hardening CLI can be found in sonic-utilities repo-
    P.R: Add support for Password Hardening sonic-utilities#2121
    code config path: config/plugins/sonic-passwh_yang.py
    code show path: show/plugins/sonic-passwh_yang.py

  3. Create a new user (using adduser command) or modify an existing password by using passwd command in the terminal. And it will now request a strong password instead of default linux policies.

Automatic Verification - Unitest:
This P.R contained unitest that cover:

  1. test default init values of the feature in PAM files
  2. test all the types of classes policies supported by the feature in PAM files
  3. test aging policy configuration in PAM files

the package in bullseye is an older version than the version that I used.
I don't think the feature will be broken if we used an older version, but I think it is better to save it.

I double-checked, you are correct, probably confused with the buster version.
I pushed a commit that is doing just apt-get install, instead download & dpkg Debian pkg
