linux-firmware: Compress firmware on disk
This patch enabled that we can compress any firmware files on disk. This
will save some space since /lib/firmware is becoming larger with every
release.
From formerly 828MiB, this is now using ~349MiB which is a saving of
about 480MiB on disk. This is helping us a lot fighting to contain the
distribution to 2GB on /.
Some other firmware that is installed in other packages is not
compressed with this patch which is a bit sad, but potentially not worth
the effort.
In order to ship this change with a Core Update, it might be intuitive
to remove /lib/firmware first and then extract the new update with all
new files. However, I do not know if this all will compress as well as
before since now the files are already individually compressed. It might
be a challenge to ship this.

TCP connections with keep-response-order enabled could leave the TCP

shut down the connection. (CVE-2022-0396) [GL #3112]
Feature Changes
DEBUG(1)-level messages were added when starting and ending the BIND
9 task-exclusive mode that stops normal DNS operation (e.g. for
reconfiguration, interface scans, and other events that require
exclusive access to a shared resource). [GL #3137]
Bug Fixes
The max-transfer-time-out and max-transfer-idle-out options were not
implemented when the BIND 9 networking stack was refactored in 9.16.
The missing functionality has been re-implemented and outgoing zone
transfers now time out properly when not progressing. [GL #1897]
TCP connections could hang indefinitely if the other party did not
read sent data, causing the TCP write buffers to fill. This has been
fixed by adding a “write” timer. Connections that are hung while
writing now time out after the tcp-idle-timeout period has elapsed.
[GL #3132]
The statistics counter representing the current number of clients
awaiting recursive resolution results (RecursClients) could

a contributing fact is that most software today has these informations

Someone now could argue that new people just a too * to look at the

think so because of several points:
First people get used to look for information at a readme. I guees that

Second starting in a new project is hard. Finding the right place where

openssl: Update to 1.1.1n
OpenSSL Security Advisory [15 March 2022]
============================================
Infinite loop in BN_mod_sqrt() reachable when parsing certificates
(CVE-2022-0778)
==================================================================================
Severity: High
The BN_mod_sqrt() function, which computes a modular square root,
contains
a bug that can cause it to loop forever for non-prime moduli.
Internally this function is used when parsing certificates that contain
elliptic curve public keys in compressed form or explicit elliptic curve
parameters with a base point encoded in compressed form.
It is possible to trigger the infinite loop by crafting a certificate
that
has invalid explicit curve parameters.
Since certificate parsing happens prior to verification of the
certificate
signature, any process that parses an externally supplied certificate
may thus
be subject to a denial of service attack. The infinite loop can also be
reached when parsing crafted private keys as they can contain explicit
elliptic curve parameters.
Thus vulnerable situations include:
- TLS clients consuming server certificates
- TLS servers consuming client certificates
- Hosting providers taking certificates or private keys from customers
- Certificate authorities parsing certification requests from
subscribers
- Anything else which parses ASN.1 elliptic curve parameters
Also any other applications that use the BN_mod_sqrt() where the
attacker
can control the parameter values are vulnerable to this DoS issue.
In the OpenSSL 1.0.2 version the public key is not parsed during initial
parsing of the certificate which makes it slightly harder to trigger
the infinite loop. However any operation which requires the public key
from the certificate will trigger the infinite loop. In particular the
attacker can use a self-signed certificate to trigger the loop during
verification of the certificate signature.
This issue affects OpenSSL versions 1.0.2, 1.1.1 and 3.0. It was
addressed in the releases of 1.1.1n and 3.0.2 on the 15th March 2022.
OpenSSL 1.0.2 users should upgrade to 1.0.2zd (premium support customers
only)
OpenSSL 1.1.1 users should upgrade to 1.1.1n
OpenSSL 3.0 users should upgrade to 3.0.2
This issue was reported to OpenSSL on the 24th February 2022 by Tavis
Ormandy
from Google. The fix was developed by David Benjamin from Google and
Tomáš Mráz
from OpenSSL.
