Hello:

What is systemctl in Devuan? Can it imitate systemd services management?

See here.

Description-en:
daemonless "systemctl" command to manage services without systemd "systemctl" is a replacement command to control system daemons without systemd. "systemctl" is useful in application containers where systemd is not available to start/stop services.

This script can also be run as init of an application container (i.e. the main "CMD" on PID 1) where it will automatically bring up all enabled services in the "multi-user.target" and where it will reap all zombies from background processes in the container. When stopping such a container it will also bring down all configured services correctly before exit.

#702 Re: Desktop and Multimedia » [Solved] xarchiver 0.5.4.14 issue » 2024-01-15 20:37:32

Hello:

I have finally made progress with xarchiver and encryption.

For better or worse, the process of adding a password to protect a compressed file using xarchiver is not too at all intuitive.

To wit:

If you open PCManFM, point to select a file and right-click/select 'Compress ...' and save it, you get exactly that.
A compressed file.

/rant start
Now ...
Do you want an extra serving of password with that?
Forget it, not on the menu.
/rant end

You have to do it the proper way:

Step 1.
Open up the xarchiver application
Applications -> Accesories -> xarchiver
Archive -> New

Step 2.
Add a name, a location to save to and and hit 'Create'
You now you have an empty *.zip file* with a name and the xarchiver UI open. 
* this provided you have chosen the default compression file type as zip in Preferences -> Preferred archive format.

Step 3.
Now ...
Action -> Add gets you the 'Add files' window where in the 'Selection' tab you can choose a file and whether to store full paths or not.

Right next to it is the 'Options' tab with the 'Actions' | 'Compression' | 'Encryption Options'.

The rest is straightforward.

Cannot imagine why pointing to select a file in PCManFM and right-clicking/selecting 'Compress ...' does not take you directly Step 3.
Maybe it is a PacManFM thing?

Right ...

Have you seen any evidence that xarchiver can do anything with encryption?

The answer is yes.
Pity that finding out how it had to be done proved to be an ordeal worthy of a much better cause.

But make no mistake, this may probably be the fastest/lightest and most versatile archiving utility for Linux.
It is mature and still works a wonder, which is why I have insisted on using it.

Problem solved.

Best,

A.

#703 Re: Other Issues » Ceph on Devuan » 2024-01-15 15:51:15

Hello:

... interesting for the larger community

Indeed.

https://docs.ceph.com/en/latest/start/o … endations/
the above claims ceph can use sysvinit or systemd

Does it?
Or is it open to interpretation?

... any distribution that includes a supported kernel and supported system startup framework ...

Does the Daedalus kernel actually fit into that definition?
ie: is sysvinit a supported system startup framework for Debian?

the below says systemd is required for cephadm
https://docs.ceph.com/en/latest/cephadm/install/

Yes.
BUT at the top of the page it has a banner that reads:

This document is for a development version of Ceph.

That said, maybe it is just showing, as with many other packages, the road to be taken as of sysvinit's demise?

Also see https://pkginfo.devuan.org/cgi-bin/pack … .2.11+ds-2

Package: cephadm
Version: 16.2.11+ds-2
--- snip ---
Depends:
adduser, lvm2, python3:any
--- snip ---
Description-en:
utility to bootstrap ceph daemons with systemd and containers
Ceph is a massively scalable, open-source, distributed
storage system that runs on commodity hardware and delivers object,
block and file system storage.

The cephadm utility is used to bootstrap a Ceph cluster and to manage
ceph daemons deployed with systemd and containers.

According to the Devuan Package information page, there is no systemd dependency in that package.

Maybe there is some detail that our (overworked) Devuan maintainers missed.

Could it be that the dyne.org system/software checks the sender's credentials ie: registered, etc. and if not rejects the message?
To be able to reject it, it has to be able to reply to the sender's email address which is why you are getting the error message.

I have sent a test message from an email account that is not registered at dng[at]lists.dyne.org.
That was roughtly 30' ago and it has not yet appeared on the list of 'newest messages'.

#709 Re: Desktop and Multimedia » [Solved] xarchiver 0.5.4.14 issue » 2024-01-06 20:46:51

Hello:

xarchiver is very fast, very lean and still works.

Seems I have made some progress ...

See this bug report against PCManFM from long ago, aparently overlooked:

https://bugs.debian.org/cgi-bin/bugrepo … bug=932461
ie: File -> Compress would not work in PCManFM 1.3.1-1

So I followed the workaround instructions and edited /usr/share/libfm/archivers.list:

[xarchiver]
# create=xarchiver --add-to %F       # create command is wrong
create=xarchiver --compress %F
extract=xarchiver --extract %F
extract_to=xarchiver --extract-to %d %F

Now compress works and I can choose from a boatload of file types.
Talk about options.  8^°

But still no joy with Action -> Enter password, which remains greyed out.
Cannot find any information on that.

Maybe I would have to see if there is a PCManFM backport for beowulf?

Just what do you think systemd and all the Linux friendly moves from the Redmond camp actually amount to?

And just who do you think are bankrolling all of it?

Redmond and their time proven "Embrace, extend, and extinguish" (EEE) never ceased.
It has always been there, laying dormant and now has set the stage to rear its ugly head again.

Meanwhile, the rest of Linuxland is furiously defending choice without coming to terms with the fact that a dead OS has no use for choice.

========================================================================
X.Org Security Advisory: December 13, 2023

Issues in X.Org X server prior to 21.1.10 and Xwayland prior to 23.2.3
========================================================================

Multiple issues have been found in the X server and Xwayland implementations
published by X.Org for which we are releasing security fixes for in
xorg-server-21.1.10 and xwayland-23.2.3.

1) CVE-2023-6377 can be triggered by forcing a logical device change on a device
with buttons which will result in an out-of-bounds memory write.

2) CVE-2023-6478 can be triggered by sending a specially crafted
request RRChangeProviderProperty or RRChangeOutputProperty. This will trigger
an integer overflow and lead to disclosure of information.

------------------------------------------------------------------------------------------------------------------------------

1) CVE-2023-6377: X.Org server: Out-of-bounds memory write in XKB button actions

Introduced in: xorg-server-1.6.0 (2009)
Fixed in: xorg-server-21.1.10 and xwayland-23.2.3
Fix: https://gitlab.freedesktop.org/xorg/xse … 4f93810afd
Found by: Jan-Niklas Sohn working with Trend Micro Zero Day Initiative

A device has XKB button actions for each button on the device. When a logical
device switch happens (e.g. moving from a touchpad to a mouse), the server
re-calculates the information available on the respective master device
(typically the Virtual Core Pointer). This re-calculation only allocated enough
memory for a single XKB action rather instead of enough for the newly active
physical device's number of button. As a result, querying or changing the XKB
button actions results in out-of-bounds memory reads and writes.

This may lead to local privilege escalation if the server is run as root or
remote code execution (e.g. x11 over ssh).

xorg-server-21.1.10 and xwayland-23.2.3 have been patched to fix this issue.

2) CVE-2023-6478: X.Org server: Out-of-bounds memory read in RRChangeOutputProperty and RRChangeProviderProperty

Introduced in: xorg-server-1.4.0 (2007) and xorg-server-1.13.0 (2012), respectively
Fixed in: xorg-server-21.1.10 and xwayland-23.2.3
Fix: https://gitlab.freedesktop.org/xorg/xse … fff81ad632
Found by: Jan-Niklas Sohn working with Trend Micro Zero Day Initiative

This fixes an OOB read and the resulting information disclosure.

Length calculation for the request was clipped to a 32-bit integer. With
the correct stuff->nUnits value the expected request size was
truncated, passing the REQUEST_FIXED_SIZE check.

The server then proceeded with reading at least stuff->nUnits bytes
(depending on stuff->format) from the request and stuffing whatever it
finds into the property. In the process it would also allocate at least
stuff->nUnits bytes, i.e. 4GB.

See also CVE-2022-46344 where this issue was fixed for other requests.

xorg-server-21.1.10 and xwayland-23.2.3 have been patched to fix this issue.

Hello:

Altoid wrote:

... anyone here give me some idea as to what could be causing this?
ie: what all this means.

Hmm ....
Maybe with some additional information?

For the sake of clarity/brevity I will skip the long story:

1.
Discovered the problem and rolled back to a VM snapshot from 30 days
ago, the oldest one I have.

Concurrently, rolled back to VBox (7.0.6) along with its
GuestAdditions 7.0.6. 

I thought that it would rule out (?) a VBox update or some corruption
in the XPSP3 VM as everything happened way after that date.   

At least I did not notice it as I do not use the XP VM often.

Problem did *not* go away.

2.
Removed VBox 7.0.6 / GuestAdditions 7.0.6, reinstalled the latest
available (7.0.12) along with GuestAdditions and the Extension Pack
which was missing.

Problem did *not* go away.

3.
Went back to the last snapshot and tried to fix things by mucking
around the XPSP3 installation but only managed to screw it up even
more.

The net result being that it is now on a 'black screen select how to
boot' and 'blue screen with whatever' loop.

4.
I attempted to add a new XP VM using three or four of the
downloadable XP isos I found on the web and was able to install one
of them as a VM.

Problem did *not* go away and shutdown does not work.
Not even shutting down X via ctrl+backspace.
Have to reboot my box.

TL;DR

The problem exists whether I use VirtualBox 7.06 or 7.0.12, with a
recovered version of the VM or the latest one.

Installing a new XPSP3 VM, whether in VirtualBox 7.0.6 or 7.0.12,
complete with GA+EP does not solve the problem.

In all cases, disconnecting the host from the web (cable and all)
does not solve the problem so phoning home does not seem to be a
posible cause.

This is (part of) what I get in a rolling dmesg screen:

------------[ cut here ]------------
--- snip ---

WARNING: CPU: 0 PID: 16511 at arch/x86/kernel/fpu/core.c:129

The warning is always the same.
ie:
at arch/x86/kernel/fpu/core.c:129 kernel_fpu_begin_mask+0xc9/0xe0

The call trace starts with the same line.
ie:
SUPR0FpuBegin+0x13/0x20 [vboxdrv]

And it is all about the same module:
ie:

? VBoxHost_RTThreadCtxHookEnable+0x32/0x40 [vboxdrv]
? VBoxHost_RTThreadCtxHookEnable+0x32/0x40 [vboxdrv]
? supdrvIOCtlFast+0x58/0xb0 [vboxdrv]
? VBoxDrvLinuxIOCtl_7_0_12+0x57/0x230 [vboxdrv]
~$ lsmod | grep vbox
vboxnetadp             28672  0
vboxnetflt             32768  1
vboxdrv               589824  4 vboxnetadp,vboxnetflt   # <- this one
~$ 

One of the important packages updated lately was linux-kbuild.
ie: 5.10.179-5~deb10u1 to 5.10.197-1~deb10u1

I understand that it is closely related to module handling by the kernel.

If anyone has a clue as to what the trace in dmesg indicates, I'm
all ears.

Thanks in advance.

Best.
