This describes more accurately that the example exposes
containerd to the host.

We already had this increased above the defaults, but even larger values
seem to be recommended.

"It’s common to tune this setting in HPC clusters, and is particularly
relevant in Kubernetes clusters since every pod has its own IP address
which consumes space in the ARP cache."

* receive: treat packet checking as irrelevant for timers
Small simplification to the state machine, as discussed with Mathias
Hall-Andersen.
* socket: check for null socket before fishing out sport
* wg-quick: ifnames have max len of 15
* tools: plug memleak in config error path
Important bug fixes.
* external-tests: add python implementation
Piotr Lizonczyk has contributed a test vector written in Python.
* poly1305: remove indirect calls
From Samuel Neves, we now are in a better position to mitigate speculative
execution attacks.
* curve25519: modularize implementation
* curve25519: import 32-bit fiat-crypto implementation
* curve25519: import 64-bit hacl-star implementation
* curve25519: resolve symbol clash between fe types
* curve25519: wire up new impls and remove donna
* tools: import new curve25519 implementations
* contrib: keygen-html: update curve25519 implementation
Two of our Curve25519 implementations now use formally verified C. Read this

- Enable RETPOLINE by default. Note, however, this will
only be used if the compiler supports it.
- Enable sysfs interface for vulnerabilities

The 4.4.14 has a number of important fixes/additions:
- New support for retpolines (enabled but requires newer gcc
to take advantage of). This provides mitigation for Spectre
style attacks.
- Various KPTI fixes including fixes for EFI booting
- More eBPF fixes around out-of-bounds and overflow of
maps. These were used for variant 1 of CVE-2017-5753.
- Several KVM related to CVE-2017-5753, CVE-2017-5715,
CVE-2017-17741.
- New sysfs interface listing vulnerabilities:
/sys/devices/system/cpu/vulnerabilities
The 4.9.77 kernel also has seems to have most/all of the above
back-ported.
See https://lwn.net/SubscriberLink/744287/1fc3c18173f732e7/
for more details on the Spectre mitigation.

If the flag is set on push, then the image will have the license
set to enabled the currently experimental netsted virtualisation
feature. The flag currently also needs to be set on run to make
sure the right CPU model (at least Haswell) is selected.

This package is primarily for users of custom or foreign
kernels which may have drivers enabled for which the
'firmware' package does not contain the firmware blobs.
Signed-off-by: Rolf Neugebauer <rolf.neugebauer@docker.com>
This new 'firmware' package contains the firmware blobs required
by the device drivers in a LinuxKit kernel. The list of required
blobs is determined by calling 'modinfo' on each module.
We also unconditionally include the AMD CPU microcode and the
licence files.
