On systems where /etc/sudoers.d might be updated often by some automated means, this
check might raise a critical when a previously present file (during the ls) is no longer
present (during its attempted read), so before raising a critical, re-check that it
does exists first.
Introduce Debian 11 compatibility
Based on CIS_Debian_Linux_11_Benchmark_v1.0.0
After review, here are the notable changes :
- Harden /var/log more (noexec,nodev,nosuid)
- Harden /var/log/audit more (noexec,nodev,nosuid)
- Harden /home more (nosuid)
- Disable cramfs
- Fix 5.3.4_acc_pam_sha512.sh
- Deprecate Debian 9 and remove useless docker images
NB : more audit log rules have been introduced and will be inserted in the checks later
Fix#158
The 99.1.3_acc_sudoers_no_all.sh script can sometimes timeout
on servers where /etc/sudoers.d/ has thousands of files.
This patch makes it run roughly 5x faster, as tested on a
server with 1500 files in sudoers.d/.
Closes#167.

When the tested server has its iptables heavily manipulated (e.g Kubernetes)
The lock aquirement can sometimes fail, hence generating false positives
The command will retry 10 times with a 1 second interval
* fix: add filter to hfs
* fix is_kernel_option_enabled check
as the module in question could have dependencies which have been blacklisted as well we need to make sure that the comparison only checks for the module in question - the last line in the output.
