Subject: [PATCH 01/23] Remove a rule from RHEL 9 OSPP
|
|
|
49eb97 |
|
|
|
49eb97 |
Remove rule sysctl_net_core_bpf_jit_harden from RHEL 9 OSPP. This rule
|
|
|
49eb97 |
requires to set net.core.bpf_jit_harden value to 2, the RHEL 9 default
|
|
|
49eb97 |
is 1. However, bpf_jit_harden=1 disables kallsyms access from bpf
|
|
|
49eb97 |
programs and all users, and it turns on constants blinding by using
|
|
|
49eb97 |
random value + XOR for CAP_BPF; so the only thing in which value 1 and 2
|
|
|
49eb97 |
differ is the constants blinding for CAP_SYS_ADMIN processes in the
|
|
|
49eb97 |
initial user namespaces. The extra constants blinding with
|
|
|
49eb97 |
bpf_jit_harden=2 does not really help with CVE mitigation.

Subject: [PATCH 02/23] Rename IDs in sysctl OVAL template
|
|
|
49eb97 |
|
|
|
49eb97 |
The sysctl template uses its sysctlvar parameter value as a part of OVAL
|
|
|
49eb97 |
object IDs, test IDs and state IDs. That means we can't have multiple
|
|
|
49eb97 |
rules using the sysctl template with the same value of sysctlvar
|
|
|
49eb97 |
parameter (only differ in other parameters) because there would be
|
|
|
49eb97 |
duplicate elements. We will fix this by using the rule ID as a part of
|
|
|
49eb97 |
OVAL object IDs, test IDs and state IDs. That will allow to use the
|
|
|
49eb97 |
template for the same sysctlvar in different rules.

Subject: [PATCH 03/23] Use a list of values in sysctl template
|
|
|
49eb97 |
|
|
|
49eb97 |
This patch adds an ability to use a list of values instead of a single
|
|
|
49eb97 |
value in the sysctlval parameter of the sysctl template. This is useful
|
|
|
49eb97 |
for situations when we want to create a rule that passes for multiple
|
|
|
49eb97 |
different sysctl values. This commit modifies the OVAL for the runtime
|
|
|
49eb97 |
configuration. The runtime configuration will be allowed to be any of
|
|
|
49eb97 |
the values in the list. There is an OR relation between the values. In
|
|
|
49eb97 |
fact, this is a first step to enable multiple values in the sysctlval
|
|
|
49eb97 |
parameter in the sysctl template, because we will also need to check the
|
|
|
49eb97 |
static configuration, which is not done in this commit.

Subject: [PATCH 04/23] Move check unrelated to the test scenarios
|
|
|
49eb97 |
|
|
|
49eb97 |
The check for an mepty list is unrelated to the test scenarios,
|
|
|
49eb97 |
rather is a generic check to avoid problems during the build.
|
|
|
49eb97 |
Therefore, it shouldn't be inside code block that is handling
|
|
|
49eb97 |
data for test scenarios, but can be extracted to a sooner position.

Subject: [PATCH 05/23] Allow multiple values in sysctl static configuration
|
|
|
49eb97 |
|
|
|
49eb97 |
This extends the OVAL checks for sysctl static configuration
|
|
|
49eb97 |
to enable a list of values instead of a single value in the
|
|
|
49eb97 |
sysctlval parameter of the sysctl template. The template
|
|
|
49eb97 |
will generate OVAL tests for each value in the sysctlval
|
|
|
49eb97 |
list.

Subject: [PATCH 06/23] Add option to allow system default
|
|
|
49eb97 |
|
|
|
49eb97 |
Introduce new template option `missing_static_pass` to the
|
|
|
49eb97 |
systemctl template. If this option is set to `"true"` in rule.yml
|
|
|
49eb97 |
the OVAL will be generated in a way that the check will pass if
|
|
|
49eb97 |
there is no sysctl static configuration option in the watched sysctl
|
|
|
49eb97 |
configuration files. In other words, the OVAL check will pass if
|
|
|
49eb97 |
the system default isn't overridden.

Subject: [PATCH 07/23] Accept multiple values in the sysctl remediation
|
|
|
49eb97 |
|
|
|
49eb97 |
A new parameter sysctlval_remediate is introduced to the sysctl
|
|
|
49eb97 |
template. This allows to choose which of the multiple values in
|
|
|
49eb97 |
the sysctl list will be used in the Bash and Ansible remediations.

Subject: [PATCH 08/23] Introduce new rule
|
|
|
49eb97 |
sysctl_kernel_unprivileged_bpf_disabled_accept_default
|
|
|
49eb97 |
|
|
|
49eb97 |
This rule is very similar to the existing rule
|
|
|
49eb97 |
sysctl_kernel_unprivileged_bpf_disabled, but it allows the sysctl
|
|
|
49eb97 |
setting kernel.unprivileged_bpf_disabled to be either 1 or 2. Also, the
|
|
|
49eb97 |
rule will pass when the explicit configuration isn't present, allowing
|
|
|
49eb97 |
to honor the system's default value which is 2. The goal of this rule is
|
|
|
49eb97 |
to prevent unnecessary modification of the RHEL system default value
|
|
|
49eb97 |
while still checking for the secure configuration.
|
|
|
49eb97 |
|
|
|
49eb97 |
See the explanation in
|
|
|
49eb97 |
https://bugzilla.redhat.com/show_bug.cgi?id=2081728:
|
|
|
49eb97 |
sysctl_kernel_unprivileged_bpf_disabled sets the
|
|
|
49eb97 |
kernel.unprivileged_bpf_disabled value to 1. However, on RHEL 9 the
|
|
|
49eb97 |
kernel supports new value 2 which per
|
|
|
49eb97 |
https://www.kernel.org/doc/html/latest/admin-guide/sysctl/kernel.html#unprivileged-bpf-disabled
|
|
|
49eb97 |
makes it for a privileged admin to re-enable unprivileged BPF. The value
|
|
|
49eb97 |
2 is also the RHEL 9 default. So the current
|
|
|
49eb97 |
sysctl_kernel_unprivileged_bpf_disabled rule unnecessarily modifies
|
|
|
49eb97 |
the RHEL 9 default.

+ The runtime status of the kernel.unprivileged_bpf_disabled
|
|
|
49eb97 |
+ kernel parameter can be queried by running the following command:
|
|
|
49eb97 |
+ $ sysctl kernel.unprivileged_bpf_disabled
|
|
|
49eb97 |
+ The output of the command should indicate either:
|

|
49eb97 |
+ kernel.unprivileged_bpf_disabled = 1
|
|
|
49eb97 |
+ or:
|
|
|

+ kernel.unprivileged_bpf_disabled = 2
|
|
|

|
49eb97 |
+ kernel.unprivileged_bpf_disabled = 0
|

+
|

|

+ The preferable way how to assure the runtime compliance is to have
|

49eb97 |
+ correct persistent configuration, and rebooting the system.
|
|
|
49eb97 |
+
|
|
|
49eb97 |
+ The persistent kernel parameter configuration is performed by specifying the appropriate
|
|
|
49eb97 |
+ assignment in any file located in the /etc/sysctl.d directory.
|
|
|
49eb97 |
+ Verify that there is not any existing incorrect configuration by executing the following command:
|
|
|
49eb97 |
+ $ grep -r '^\s*{{{ sysctl }}}\s*=' /etc/sysctl.conf /etc/sysctl.d
|
|
|
49eb97 |
+ The command should not find any assignments other than:
|
|
|
49eb97 |
+ kernel.unprivileged_bpf_disabled = 1

|
|
|

Subject: [PATCH 13/23] Introduce sysctlval_wrong parameter
|
|
|
49eb97 |
|
|
|
49eb97 |
When the `sysctalval` parameter is a list, this parameter will be
|
|
|
49eb97 |
substitued into the SYSCTL_WRONG_VALUE parameter in test scenarios. This
|
|
|
49eb97 |
is better than current computing of the SYSCTL_WRONG_VALUE parameter
|
|
|
49eb97 |
which is done by prepending "1" to the string value, because the
|
|
|
49eb97 |
computed value could be invalid and the `sysctl -w` command used in the
|
|
|
49eb97 |
test scenario wrong_runtime.fail.sh could fail to set the value to
|
|
|
49eb97 |
SYSCTL_WRONG_VALUE therefore not changing the runtime. If at the same
|
|
|
49eb97 |
time the `missing_static_pass` is set to `true` and the system is set to
|
|
|
49eb97 |
system default, then the unchanged runtime would cause the check to pass
|
|
|
49eb97 |
and therefore the test scenario wrong_runtime.fail.sh to error.

Subject: [PATCH 15/23] Simplify sysctl template
|
|
|
49eb97 |
|
|
|
49eb97 |
Instead of using multiple OVAL tests in OR relation we can have
|
|
|
49eb97 |
a single OVAL test containing multiple OVAL states in OR relation.
|
|
|
49eb97 |
That will simplify the code.

Subject: [PATCH 16/23] Replace the sysctlval_remediate template parameter
|
|
|
49eb97 |
|
|
|
49eb97 |
Replace the sysctlval_remediate template parameter by using an XCCDF
|
|
|
49eb97 |
value. The variable would be only used in the remediation and would
|
|
|
49eb97 |
allow users to tailor the value, instead of the current solution where
|
|
|
49eb97 |
the value is hardcoded and can be only changed during build time.

Subject: [PATCH 18/23] Rename parameter missing_static_pass
|
|
|
49eb97 |
|
|
|
49eb97 |
Rename the parameter missing_static_pass to missing_parameter_pass
|
|
|
49eb97 |
to make the naming consistent with other templates where a parameter
|
|
|
49eb97 |
with a similar meaning exist.
