Do not bump to a more recent version, as the build system has
fundamentally changed.
See the release notes:
- https://github.com/netdata/netdata/releases/tag/1.34.0
- https://github.com/netdata/netdata/releases/tag/v1.34.1
- https://github.com/netdata/netdata/releases/tag/v1.35.0

In addition, add upstream patch to fix cross-compilation.
This fixes the following vulnerabilities:
- CVE-2023-22496:
Netdata is an open source option for real-time infrastructure
monitoring and troubleshooting. An attacker with the ability to
establish a streaming connection can execute arbitrary commands on the
targeted Netdata agent. When an alert is triggered, the function
`health_alarm_execute` is called. This function performs different
checks and then enqueues a command by calling `spawn_enq_cmd`. This
command is populated with several arguments that are not sanitized.
One of them is the `registry_hostname` of the node for which the alert
is raised. By providing a specially crafted `registry_hostname` as
part of the health data that is streamed to a Netdata (parent) agent,
an attacker can execute arbitrary commands at the remote host as a
side-effect of the raised alert. Note that the commands are executed
as the user running the Netdata Agent. This user is usually named
`netdata`. The ability to run arbitrary commands may allow an attacker
to escalate privileges by escalating other vulnerabilities in the
system, as that user. The problem has been fixed in: Netdata agent
v1.37 (stable) and Netdata agent v1.36.0-409 (nightly). As a
workaround, streaming is not enabled by default. If you have
previously enabled this, it can be disabled. Limiting access to the
port on the recipient Agent to trusted child connections may mitigate
the impact of this vulnerability.

- CVE-2023-22497:
Netdata is an open source option for real-time infrastructure
monitoring and troubleshooting. Each Netdata Agent has an
automatically generated MACHINE GUID. It is generated when the agent
first starts and it is saved to disk, so that it will persist across
restarts and reboots. Anyone who has access to a Netdata Agent has
access to its MACHINE_GUID. Streaming is a feature that allows a
Netdata Agent to act as parent for other Netdata Agents (children),
offloading children from various functions (increased data retention,
ML, health monitoring, etc) that can now be handled by the parent
Agent. Configuration is done via `stream.conf`. On the parent side,
users configure in `stream.conf` an API key (any random UUID can do)
to provide common configuration for all children using this API key
and per MACHINE GUID configuration to customize the configuration for
each child. The way this was implemented, allowed an attacker to use a
valid MACHINE_GUID as an API key. This affects all users who expose
their Netdata Agents (children) to non-trusted users and they also
expose to the same users Netdata Agent parents that aggregate data
from all these children. The problem has been fixed in: Netdata agent
v1.37 (stable) and Netdata agent v1.36.0-409 (nightly). As a
workaround, do not enable streaming by default. If you have previously
enabled this, it can be disabled. Limiting access to the port on the
recipient Agent to trusted child connections may mitigate the impact
of this vulnerability.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
