I think Ubuntu is tracking Debian.

The Debian package is located at
https://packages.debian.org/bullseye/trustedqsl (Bullseye is the
latest Debian Stable). On the right, there is "Developer Information",
which eventually leads back to SourceForge.

From Debian's Developer Information page, the package is maintained by
debian-h...@lists.debian.org. And it looks like Debian supplies
2.5.7-1 in Stable, and 2.6.3-1 in Unstable.

It will take some time for the package to move from Debian Unstable to
Debian Testing and finally Debian Stable. Debian Testing is also where
the next stable release is tested. So 2.6.3 will be available in
Debian Bookworm, which is Debian's next stable release.

So, I don't think Ubuntu will be able to update to 2.6.3 anytime soon.
Ubuntu will probably stay at 2.5.7. If you want 2.6.2 or above, you
will probably have to build it yourself in the near future.

Please backport kernel patches for ACPI parsing errors

2022-06-29 Thread Jeffrey Walton
Hi Everyone,

Some machines experience ACPI parsing errors. Also see
https://bugzilla.kernel.org/show_bug.cgi?id=201981 . Comment 24 offers
that Ubuntu should consider backporting these two commits:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dc6a6ab58379f25bf991d8e4a13b001ed806e881

It would be helpful if the Ubuntu kernel maintainers backported the commits.

Thanks in advance.

One area Linux is not user friendly is a simple-to-use Senior edition.
I think this is an instance problem of Accessibility.

I've found I can't set the font to a larger size without hassles and
troubles. Even if you manage to increase the font size for the
particular desktop, the boot and login screens don't honor the
settings.

It would be nice to set the font size in one place, and have it used
everywhere. For senior citizens and visually impaired users.

Start here: https://packages.ubuntu.com/. Select a Release. Scroll

memcached.

It looks like 1.5.6 is part of Bionic. SO ga back one release from Bionic.

Yes, you're right. do-release-upgrade looks like the similar command.

Do you know if do-release-upgrade will move from one LTS version to
another? I usually select Ubuntu LTS when I want long term stability,
like over 3 or 5 years. In fact, my main desktop machine is Ubuntu
18.04 LTS.

Fedora does not really offer long term stability. Fedora is more
suited for the latest stable release every 6 months. Select it when
you want as close to the bleeding edge as possible while staying
stable.

You can see Nginx versions supplied with Ubuntu releases by searching
packages at https://packages.ubuntu.com/.

But you may be interested in... Nginx is pretty easy to build from
sources. It has several dependencies - zLib, PCRE and OpenSSL. None of
them are difficult to build, and all of them are available from
Ubuntu, so you don't need to build them yourself.

The downside to Nginx is a non-standard configure program. Nginx does
not do things like most other packages. It also has a lot of options
so you will need to spend some time at
https://nginx.org/en/docs/configure.html.

In case anyone is interested... I have a GitHub that allows us to
install modern cURL, Wget, Git, SSH, etc. It is a hack and piss-poor
excuse for a package manager, but it works great on this old stuff to
get modern tools. The rub is, we need autotools, a compiler, and a few
other tools to get started. You can find it here:
https://github.com/noloader/Build-Scripts.

Set up an antique machine for testing

2022-01-10 Thread Jeffrey Walton
Hi Everyone,

I need to test a few security controls for an antique piece of
hardware and software. The antique software includes Java 1.5
environment (SEPT 2004 - NOV 2009). The company has not been able to
upgrade for several reasons, and I don't have control over it.

I want to install a Ubuntu Server from that era. Hardy/8.04 was
contemporary around that time. I found the ISO at
https://old-releases.ubuntu.com/releases/. I doubt there are any Hardy
mirrors out there nowadays.

I need to get autotools, package-config, gcc, python and perl
installed. I also need to get Java or OpenJDK installed, which should
be about Java 1.5.

Apt wants to update its index files which is pointless for this setup.
It results in an error that stops subsequent install operations.

My question is, how do I get 'apt-get install' to work in this case?

Thanks in advance.

Related, if you want the latest version of a package like Wireguard
(or GCC, or Python, or Perl, ...), then you might want to look at
Fedora.

Fedora has a 6 month release cycle. Each version you are on has the
latest releases of its packages and gets full updates. And in 6 months
you move onto the next stable version. At the 6 month release in the
life cycle, you simply run dnf-system-upgrade [1] and you are on the
next version of Fedora. dnf-system-upgrade is a lot like a Ubuntu
dist-upgrade.

I really like Fedora's model, the use of SELinux in enforcing mode,
and Fedora's desire to provide the latest versions of software. In
fact, I run Fedora Workstations to test the latest GCC compilers, and
Fedora Servers when I need a web server.

I no longer bother with CentOS or Red Hat servers. I can't stand that
antique software that makes you use Software Collections (SCL) to get
something semi-modern. I gave up on CentOS and Red Hat servers when
trying to get Mediawiki running on them. CentOS and Red Hat servers
with their old software was just too much work.

I also use Ubuntu workstations and servers. But every now and again
you want the latest software for a server, and that's when you want to
consider Fedora.

Add a ca root to ca-certificates in WSL environment?

2021-12-13 Thread Jeffrey Walton
Hi Everyone,

I'm working on a Windows machine with Windows Subsystem Linux (WSL).
The machine hosts Ubuntu 20.04. We are having some TLS problems due to
an interception proxy. I need to add a CA root to the ca-certificates
package or store.

I checked the Ubuntu wiki and found one article on ca-certificates at
https://wiki.ubuntu.com/IncidentReports/2011-09-20-ca-certificates-removes-libnss3.

I'm Ok with dropping the root CA in the filesystem and running
c_rehash, if needed. I'm happy to use the method if that is
recommended.

My question is, how would I go about adding a root CA to the machine's
trusted root store?

Thanks in advance.

Typically (or most often with GNU software) you run a configure
script. There is literally a script called 'configure' in the tarball.
The configure script generates the makefiles for you.

GNU software comes with README and INSTALL files. You should check
them for instructions on building and installing the software. For
non-GNU software you have to look through the files provided in the
tarball.

I'm not familiar with SBCL. If it is https://github.com/sbcl/sbcl,
then it looks like you may need to run install.sh. See the INSTALL
file for details at https://github.com/sbcl/sbcl/blob/master/INSTALL.

In the old days you just installed ia32-libs.

Nowadays you do something like this:

$ sudo apt-get install lib32z1 lib32ncurses5
$ sudo apt-get install gcc-multilib gcc-7-multilib
$ sudo apt-get install g++-multilib g++-7-multilib

You should check the version of GCC that comes with the platform and
use the specific version when installing. My -m32 test system happens
to use GCC 7 by default, hence gcc-7-multilib and g++-7-multilib.

If you have dependencies, then you use the :i386 syntax, like:

$ sudo apt-get install libfoo:i386

Also see https://help.ubuntu.com/community/MultiArch, which is kind of
dated nowadays.

Re: rng-tools and VIA chipsets with Padlock

2021-05-17 Thread Jeffrey Walton

This looks like a problem I encountered in the past with rng-tools.
The problem in the past was, rngd is an old System V service. It does
not start correctly under Systemd.

I believe I fixed the problem in the past using a proper Systemd
service file. In fact, I think sysv wrapper would actually work if
Systemd retired the failed start.

rng-tools and VIA chipsets with Padlock

2021-05-17 Thread Jeffrey Walton
Hi Everyone,

I have an old VIA C7-D machine I use for testing Padlock. Padlock is a
security engine provides AES, SHA and a RNG for some of the VIA
processors. (It predates Intel's gear by about 15 years).

With rng-tools installed I'm seeing failures in /dev/random. Draining
/dev/random and then trying to read from it is causing prolonged
blocking. Blocking should not occur since Padlock has a hardware RNG.

It also appears draining /dev/random is breaking /dev/urandom.
/dev/urandom is blocking on 1024 bytes. It took about 6 minutes to
read 1024 bytes from /dev/urandom after draining /dev/random.

I pinged Thorsten and Henrique but did not receive a response.
(Henrique is CC'd in case it fell off his radar).

I believe this is the package:
https://packages.ubuntu.com/bionic/rng-tools. But I may be mistaken.

My question is, is this something Ubuntu would like to investigate?

Description-en: Daemon to use a Hardware TRNG
 The rngd daemon acts as a bridge between a Hardware TRNG (true random number
 generator) such as the ones in some Intel/AMD/VIA chipsets, and the kernel's
 PRNG (pseudo-random number generator).
 .
 It tests the data received from the TRNG using the FIPS 140-2 (2002-10-10)
 tests to verify that it is indeed random, and feeds the random data to the
 kernel entropy pool.
 .
 This increases the bandwidth of the /dev/random device, from a source that
 does not depend on outside activity.  It may also improve the quality
 (entropy) of the randomness of /dev/random.
 .
 A TRNG kernel module such as hw_random, or some other source of true
 entropy that is accessible as a device or fifo, is required to use this
 package.
 .
 This is an unofficial version of rng-tools which has been extensively
 modified to add multithreading and a lot of new functionality.

Clang 10 patch for function multiversioning

Hi Everyone,

Would you mind picking up this patch for Clang 10 on Ubuntu 18?

* https://github.com/llvm/llvm-project/commit/0ed613612c5d

It looks like Clang is up to version 12. The patch may apply to 11 and 12, too.

Ubuntu 16 is kind of old...

I would start by trying to get the machine in a good state:

  $ sudo dpkg --configure -a
  $ sudo apt install -f

followed by:

  $ sudo apt update
  $ sudo apt upgrade

Then, attempt the install.

I would not be surprised if a modern libpng package cannot be
installed on an old Ubuntu. In this case, you might want to build
libpng from sources.

Power problem with Radeon 7750 card and Nouveau driver

2021-02-09 Thread Jeffrey Walton
Hi Everyone,

I'm working on Ubuntu 20.04, x86_64, fully patched. It has the
5.4.0-64 kernel. The machine is a Dell XPS 8930 with an i7-8700,
https://www.amazon.com/gp/product/B078N85NCR.

I'm having a power management problem. The monitor goes to sleep and
does not wake up. Power Management applet settings are (a) turn
monitor off after 15 minutes, and (b) never go to sleep. Moving the
mouse and tapping on the keyboard does not seem to wake the monitor.
In this state I can SSH into the machine.

I think this issue has to do with Noveau. The problem started after I
removed the original GeForce GTX 1060 (Nvidia driver) and installed a
Radeon 7750 (Nouveau driver). I switched cards for the open source
driver. The Radeon 7750 card is
https://www.amazon.com/gp/product/B00C7EPSVS. The monitor cable is
HDMI to Mini DisplayPort. It is a new cable for use with the Radeon
card. https://www.amazon.com/gp/product/B00YONKZ72.

I have the package xserver-xorg-video-nouveau installed. I removed all
the Nvidia and purged all the packages.

The logs I have found look like this (from log viewer):


12:10 PM radeon_dp_aux_transfer_native: 2510 callbacks suppressed
 2:00 PM radeon_dp_aux_transfer_native: 1040 callbacks suppressed

 2:01 PM [drm:radeon_dp_link_train [radeon]] *ERROR* displayport link

 2:01 PM [drm:radeon_dp_link_train [radeon]] *ERROR* clock recovery failed
 2:01 PM [drm:radeon_dp_link_train [radeon]] *ERROR* displayport link
status failed
 2:01 PM [drm:radeon_dp_link_train [radeon]] *ERROR* clock recovery failed
 2:05 PM radeon_dp_aux_transfer_native: 566 callbacks suppressed


I searched Freedesktop's GitLab issues
(https://gitlab.freedesktop.org/drm/nouveau/-/issues) related to
"*ERROR* displayport link status failed" and "*ERROR* clock recovery
failed". GitLab did not return any hits.

I noticed I was missing the nouveau-firmware package. When I added it
I lost the monitor completely. The monitor displayed a message similar
to "No HDMI signal present", even during a reboot. nouveau-firmware
definitely made things worse. Removing nouveau-firmware did not help.
The "No HDMI signal" problem persisted. I had to switch back to the
GeForce card and the Nvidia driver.

Does anyone have suggestions how to troubleshoot this further?

That would be a bad idea. Asking people without knowledge of the
problem domain is just plain stupid. It is a recipe for disaster.

The people with the knowledge of the problem domain should perform the work.

Sorry, but I have no idea what the policies say.

Leaving IPv6 broken in 2018 or 2020 means there's a broken policy in
place, if that's the case. We (in the US) have been experiencing a lot
of broken policies lately. Like the ones that allow police to murder
black people at will without any accountability.

Broken policies carry no weight with me.

Wget 1.21 was released on DEC 31, 2020. It is still failing its self tests.

Is there any hope of getting Perl fixed before Ubuntu 18 goes end-of-life?

Ubuntu 18.04 and "Bad arg length for Socket::inet_ntoa" when using IPv6

2020-12-12 Thread Jeffrey Walton
Hi Everyone,

Would someone have a look at
https://bugs.launchpad.net/ubuntu/+source/libhttp-daemon-perl/+bug/1904907
when time is available.

The issue causes self tests failures in a lot of packages, including
Wget and Wget2. When 'make check' fails it munges up the install
process. We don't have authority to install a package that fails its
self tests.

If I am parsing the issue properly, the fix has been available for
several years. This may also be helpful from Red Hat
https://access.redhat.com/errata/RHBA-2018:0665:

* BZ - 1413065 - HTTP-Daemon does not support IPv6: Arg length for inet_ntoa
* BZ - 1492760 - IO::Socket::IP->new() fails to listen on unspecified
local address

Thanks Dimitri,

It's nothing urgent. The issue fell out of a script I was working on.
But I've got a feeling it's going to take a few years for the kmod
changes to become readily available.

I'll probably switch to a C program using OpenSSL to do it.

Ubuntu 18.04 and "sig_hashalgo: md4"

2020-09-05 Thread Jeffrey Walton
Hi Everyone,

Ubuntu 18.04's modinfo looks like it is subject to
https://bugzilla.redhat.com/show_bug.cgi?id=1320921 and
https://bugzilla.redhat.com/show_bug.cgi?id=1490975.

$ modinfo crypto_simd
filename:   /lib/modules/5.3.0-66-generic/kernel/crypto/crypto_simd.ko
license:GPL
srcversion: 701320EC07F22E0D8427859
depends:cryptd
retpoline:  Y
intree: Y
name:   crypto_simd
vermagic:   5.3.0-66-generic SMP mod_unload
signat: PKCS#7
signer:
sig_key:
sig_hashalgo:   md4

A quick Google search did not pick up a similar Ubuntu bug report,
like Red Hat's 1320921 and 1490975.

It looks like the fix was checked in about a year and a half ago. Also
see https://lwn.net/Articles/779249/.

Would it be possible to pick up the fix?

Thanks in advance.

Crypto++ and Patch for CVE-2015-2141 committed

2015-06-27 Thread Jeffrey Walton
Hello,

You are receiving this email because you are (or were) listed as a
package maintainer for Crypto++. Emails are also being sent to the
well known security@ address from RFC 2142. Please accept apologies if
you receive this email multiple times.

Crypto++ committed the patch for CVE-2015-2141 today. For SVN, the
commit of interest is r542. You can find it at
https://sourceforge.net/p/cryptopp/code/542/. For GitHub, the commit
of interest is 9425e16437439e68c7d96abef922167d68fafaff. You can find
it at 
https://github.com/weidai11/cryptopp/commit/9425e16437439e68c7d96abef922167d68fafaff.

* CVE-2015-2141 Details *

Evgeny Sidorov discovered he could recover the private key when using
Rabin-Williams signatures due to a bad interaction with the blinding
value used to mask private key operations. The bad interaction had to
do with the random value not meeting certain Jacobi requirements. The
full writeup can be found at https://eprint.iacr.org/2015/368.

Jean-Pierre Münch suggested a simple fix to avoid the bad interaction:
square the random value. Squaring the random value meant the value
satisfied the Jacobi requirements, and it avoid trial-and-error on
producing the random value in a loop. Avoiding trial-and-error saved
about 6-8 iterations of the loop, and about 12 Jacobi tests on
average.

* Obtain the latest sources *

To checkout from SVN, issue:

   svn checkout https://svn.code.sf.net/p/cryptopp/code/trunk/c5 cryptopp

To clone from Wei Dai's GitHub, issue:

git clone https://github.com/weidai11/cryptopp.git cryptopp

The ZIP files from the website do *not* include the latest revisions.
You should not build a package based upon it.

* DataDir patch *

As a maintainer, you may be interested in the DataDir patch. The patch
ensures the self tests and benchmarks run after the library is
installed.

For the patch and a script to help integrate it, see
http://www.cryptopp.com/wiki/DataDir.
