But nobody likes checking configs manually. So let the computers do their job!
__kconfig-hardened-check.py__ helps me to check the Linux kernel Kconfig option list
-against my hardening preferences for `x86_64`, which are based on the
-[KSPP recommended settings][1] and last public [grsecurity][2] patch (options
-which they disable).
+against my hardening preferences, which are based on the
+
+ - [KSPP recommended settings][1],
+ - [CLIP OS kernel configuration][2],
+ - last public [grsecurity][3] patch (options which they disable).
Please don't cry if my Python code looks like C. I'm just a kernel developer.
+## Supported microarchitectures
+
+ - X86_64
+ - X86_32
+ - ARM64
+ - ARM

## Script output examples
### Usage
```
-#./kconfig-hardened-check.py
-usage: kconfig-hardened-check.py [-h] [-p] [-c CONFIG] [--debug]
+usage: kconfig-hardened-check.py [-h] [-p {X86_64,X86_32,ARM64,ARM}]
+ [-c CONFIG] [--debug] [--json]
Checks the hardening options in the Linux kernel config
optional arguments:
-h, --help show this help message and exit
- -p, --print print hardening preferences
+ -p {X86_64,X86_32,ARM64,ARM}, --print {X86_64,X86_32,ARM64,ARM}
+ print hardening preferences for selected architecture
-c CONFIG, --config CONFIG
check the config_file against these preferences
--debug enable internal debug mode
+ --json print results in JSON format
+
```

+
+### Questions and answers
+
+__Q:__ How disabling `CONFIG_USER_NS` cuts the attack surface? It's needed for containers!
+
+__A:__ Yes, the `CONFIG_USER_NS` option provides some isolation between the userspace programs,
+but the script recommends disabling it to cut the attack surface __of the kernel__.
+
+The rationale:
+
+ - A nice LWN article about the corresponding LKML discussion: https://lwn.net/Articles/673597/
+
+ - A twitter thread about `CONFIG_USER_NS` and security: https://twitter.com/robertswiecki/status/1095447678949953541
+
+<br />
+
+__Q:__ Why `CONFIG_GCC_PLUGINS` is automatically disabled during the kernel compilation?
+
+__A:__ It means that your gcc doesn't support plugins. For example, if you have `gcc-7` on Ubuntu,
+try to install `gcc-7-plugin-dev` package, it should help.
