Yes, that seems to be exactly my problem. So it's not intentionally
disabled. Then I can hope that it may be fixed some day. Thanks for

To be precise, it is the passphrase do decrypt your *private* key. A 
public key may be known to anybody. Private key is a secret that allows 
to prove that you have it without disclosing of this private key. 
Encryption using a passphrase is a means to mitigate consequences if the 
private key is stolen.


An ssh agent opens a socket and exposes its location through an 
environment variable (perhaps using "systemctl set-environment", but I 
am not sure). Try


env | grep SSH

There are multiple implementations of SSH agents: openssh, gpg, 
keepassxc(?), perhaps gnome has more (seahorse? I am unsure concerning 
the role of secrets service). It may happen that in your case multiple 
instances are running:


/usr/lib/systemd/user/ssh-agent.service
/usr/lib/systemd/user/gpg-agent-ssh.socket
/etc/X11/Xsession.d/90x11-common_ssh-agent

GUI prompt may be just a proxy to an actual ssh agent. It just listens 
its socket and displaying a password prompt on demand and passing other 
messages literally.



Now, while typing this email all keyring PIDs have vanished!


It may be a way to minimize RAM usage. The agent may be a 
socket-activated process.


systemctl --user list-sockets

Check owner of $SSH_AUTH_SOCK using ss or lsof. It may give some clue 
what is really happening in your case.


I suggest you to add "f" option to "ps" to see process tree. It may help 
to find details concerning starting of particular agent.


   ps xwwf

P.S. At certain moment gnome designers decided that password prompt must 
be a modal dialog completely blocking interaction with any other 
applications (including 3rd party password manager). For me it was 
another reason to avoid gnome. I am aware that X11 protocol allows to 
sniff keyboard events and a measure against it is grabbing input. 
However I believe mouse still may be a way to call an external password 
manager. After all, there are may be an option to temporary suspend 
keyboard grabbing. I learned about multiple ways to start a ssh agent 
during initialization of user session when I was trying to figure out 
which way GUI prompt is implemented and if a more flexible dialog could 
be used instead.

FWIW, I've had very serious write performance issues on my Thinkpad T61
(8GB RAM + SSD) when using a 32bit PAE kernel (occasionally below 1MB/s,
tho not reliably reproducible, e.g. not right after boot).

Those problems disappeared when I switched to an amd64 kernel (while
keeping the userland 32bit).

https://serverfault.com/questions/996495/writes-throttled-to-500kb-s

Your symptoms seem quite different, but with 16GB of RAN, I'd strongly
suggest you try an amd64 kernel, just in case.

Re : FFMPEG ?

Bonjour Ptitlou,
Je ne sais pas pour FFMPEG, mais tu parles aussi de format RAW pour Canon.

Pour ce point UFRAW existe soit en plugin pour GIMP, soit en utilitaire 
indépendant.
L'interface indépendante permet de tirer le meilleur des fichiers RAW.
Cela demande un peu d'apprentissage par essais de manipulation mais on obtient 
de très bons résultats.

quelqu'un connait une avec Debian ?
(onworks[dot]net/fr/programs/ffmpeg-all-online?amp=0)

Et en plus comme pour Canon, le rendu image/video donne quoi ? 
Y a t'il une amélioration concrete ?

J'ai une IA qui me veillit les personnes donc améliorer la qualité c'est pas 
plus facile sous Debian ?
( Je ne sais pas si l'IA est libre ?)

Sinon en proposition d'amelioration je vien de me rendre comptze que les

Thanks for that! I think I had searched the bug list but somehow did
not find that bug. Glad to know that it has already been reported.
There is plenty of detail in there so no need for me to add to it. I
did a quick test a few minutes ago and can confirm that disabling
paravirtualization fixes the issue, as stated in the last comment in
the bug report. So it is good that there are two workarounds, and this
one is better than disabling EFI in some use cases.

Disk writes much slower in Bookworm i386 [Was: svnadmin dump ...]

[kjohnson]

I have done additional research, and it now appears that programs that do 
extensive disk writes run much slower (3-6x) in Bookworm than they did in 
Bullseye.  The two cases I have observed are 'svnadmin dump', and extracting an 
SQL backup of a Bacula database from Postgresql (backup file about 3 GB).  
Operations that perform extensive reads (a Bacula backup operation to magnetic 
tape, 600 GB) seem to run at the same speed as before.

At the moment, this is a 32-bit PAE system.  I don't know of an obvious reason 
why that would matter.  At the time of the upgrade, the system memory was 
enlarged from 16 to 32GB, in anticipation of converting the system from i386 to 
amd64.

Suggestions for tracking this down would be welcome.

Subject: svnadmin dump much slower in Bookworm

A set of svnadmin dump commands that run as part of a backup procedure seem to 
be _much_ slower in Bookworm than in Bullseye.  Prior to the upgrade to 
Bullseye, these commands took slightly less than one hour.  After the upgrade, 
similar commands (dumping a few more revisions) require more than six hours.  
The script that performs these commands has not been changed.  Has anyone else 
seen this problem?

Thanks,

Ken
 
 

Please could we calm down? [WAS List administrators - request]

[Andrew M.A. Cater]

People,

I'm not claiming any huge authority here: I'm a volunteer here and a reader
and contributor.

Recent threads have got out of hand, at least in part.

It is *really helpful* to be constructive and to try and put yourself in
someone else's place. There have been long rambling threads, some degree
of discontent and personal attacks. 

These don't help those reading this list for the first time. They don't help
the reputation of this list for long rambling threads that don't go anywhere.
They don't help people who actually come here seeking help for a Debian
problem.

Can I ask people to reconsider immediate responses to threads if you can
avoid it - sit on your hands for six hours or so and see if anyone else
jumps in before adding more UNLESS you can help someone immediately.

I post the FAQ every month in an effort to explain how this list might work.
Debian is odd because we still use mailing lists. Not everyone knows
to avoid top-posting, how to formulate a clear reply.

The Code of Conduct applies here as elsewhere in Debian: try and make this
a welcoming, useful place. You never know who you might help or who might
be driven away by someone's bad attitude.

Can we try this for a couple of days, please? If you can't add help 
immediately,maybe wait?

With thanks for your consideration

So apparently randomness from a TPM is completely disabled in Debian 12

Debian Bug #1041007
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1041007#10

 Message #10
 From: Vincent Blut
 [...]
 Subject: linux-image-6.1.0-0.deb11.7-amd64: Please enable TPM hardware RNG 
support (CONFIG_HW_RANDOM_TPM)
 Date: Sat, 29 Jul 2023 00:33:35 +0200

 [...]
 Indeed, this regression compared to the kernel provided in bullseye
 is due to a configuration issue.
 For HW_RANDOM_TPM to be enabled, the TCG_TPM and HW_RANDOM config
 symbols are required but there is a subtlety in the way they have to
 be built. If TCG_TPM is built-in then HW_RANDOM must not be loadable
 (built as a module).

 If we take a look at the kernel configuration files prior being
 constructed, we can see that both TCG_TPM and HW_RANDOM config
 symbols should be built as modules:

 $ grep -Er "TCG_TPM|HW_RANDOM="
 arm64/config:CONFIG_TCG_TPM=m
 kernelarch-x86/config:CONFIG_TCG_TPM=m
 config:CONFIG_HW_RANDOM=m
 config.cloud:CONFIG_TCG_TPM=m

 However after these files have been constructed, the TCG_TPM config
 symbol is no longer provided as module but built-in:

If it worked, you will find in the syslog :

Should you specifically need UEFI next time, an alternative solution
can be to temporarily disable KVM paravirtualization (default for
Linux-based guests). It can be reenabled back after you are done with
installation. See

Thanks. And look at that:

# grep CONFIG_HW_RANDOM_TPM /boot/config-*
/boot/config-5.10.0-23-amd64:CONFIG_HW_RANDOM_TPM=y
# grep CONFIG_HW_RANDOM_TPM /boot/config-6.1.0-11-amd64 ; echo $?
1

So apparently randomness from a TPM is completely disabled in Debian 12
regardless of manufacturer. Next question: Why?

Unfortunately no matter how advanced your MUA is, it doesn't help
against prolific posters who derail nearly every thread with
copious amounts of irrelevance and outright false information.


This is a higher bar than merely neutralising the disruption (to
one's own use of the list) caused by a popular thread that one has
little interest in.

And here, my instincts are screaming "Leave it here. Stop
now. Leave well enough alone for the sake of all that is holy!"

However, and speaking only for myself, I'll bite:

Being able to see a thread's messages structured as a tree of
message headers (author, subject) can indeed help me infer quite a
bit about what's going on, before I bother to dig in and actually
read any of the messages' content.

For example, let P and Q be two regularly prolific participants, P
with exceptionally high signal-to-noise contributions, and Q a hot
willfully clueless mess. If there is a branch of the tree that is
just a chain of back-and-forth between P and Q --Q.P.Q.P.Q...--
then I know what's going on in there and so some OTHER branch will
be my first destination, unless I'm in the mood for a laugh.


You can easily see from looking at most of the large threads here,
the points at which they go off the rails and the common factors
involved there.


I can indeed. Without seeing the tree structure, I do not think it
would be so easy to see.


It is a difficult problem to solve as mailing lists like this tend
to promote a volume-wins approach,


You may be correct, but this isn't clear to me. (Unless the object

and the baseline user will not have an advanced MUA nor necessarily
the experience to know that they're reading nonsense.


When I conquer the world, you will know because /etc/motd will
contain something like this:

   Don't enter commands you don't understand, and you won't
   understand the commands unless you read the manual. If you read
   the manual, you STILL may not understand the
   commands. Nevertheless, keep trying, Curious Human. We are
   rooting for you!


Things get easier when you use an advanced MUA, so people should
invest the time to do so, but let's not pretend that this will avoid
a mega-thread next time some outlandish thread hijack by one of the
usual suspects happens.


My point was simply this: threads I've lost interest in (regardless
of size) are a single line in my mailbox, provided I do not delete
its initial message.


Does this particular thread go much better if you assume that
everyone participating (except the OP, who doesn't know how to
unsubscribe, or how to spell it) is fully competent at efficiently
managing email but still posts as they posted?


Funnily enough, if you look carefully, you can see some utterly
slapstick confusion of that very nature in this thread, over who is to

I'm not a priest. And, just for the record since you seem to have read
me otherwise, I happen to think everyone's behavior so far has been
pretty normal human behavior, given reasonable assumptions about what
each knew at the time of their respective contributions.

The sheer normality of it is what makes it a good example, and perfect
comedy.


I sincerely apologize for posting an incorrect link to an Alpine
mailing list.  I am so sorry I troubled you for it.  I hope you can
find it in your heart to forgive me for the transgression, and the
inconvenience I caused to all members of the list.


I welcome your evident sarcasm here as a sign that we both agree that

I see the 6.1 branch contains the first attempt at working around the
stutter problem, which disables randomness only from certain known
broken firmware versions:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/char/tpm/tpm-chip.c?h=linux-6.1.y#n510

It's supposed to log a warning when it takes effect:
"AMD fTPM version 0x%llx causes system stutter; hwrng disabled\n"
That message does not appear in my logs.

The new workaround, which disables randomness from all AMD firmware TPUs
and doesn't log, can be in effect only if it has been backported to
Debian's kernel very recently. That does not seem to be the case, if
this is the right way to look for backports:
https://salsa.debian.org/kernel-team/linux/-/commits/bookworm/

I'll check what the manufacturer number is on my system, if I can
figure out how to get at it.

The only loaded module with "rng" in its name is "rng_core". That one
is present in both kernels, but four TPM-related modules are absent
from Linux 6.1:

# uname -v
#1 SMP Debian 5.10.179-3 (2023-07-27)
# lsmod | egrep -i 'rng|tpm'
tpm_crb20480  0
tpm_tis16384  0
tpm_tis_core   28672  1 tpm_tis
tpm73728  3 tpm_tis,tpm_crb,tpm_tis_core
rng_core   16384  3 ccp,tpm

# uname -v
#1 SMP PREEMPT_DYNAMIC Debian 6.1.38-3 (2023-08-07)
# lsmod | egrep -i 'rng|tpm'
rng_core   20480  1 ccp

And yet /dev/tpm0 exists in both kernels, but disappears when I
physically remove the TPM, so the TPM is recognized to some degree even
without those modules.

Those four TPM-related modules are also present as files under
/lib/modules in Linux 5.10, but absent in Linux 6.1. The corresponding
source files still exist in the source tree. Have they been disabled in
Debian 12? Have they been moved to some "extra modules" package that I
haven't found? Or are they just not modules because they're statically
built-in?

> or identify the rng hardware a little better

As I wrote in my first email, it seems to be an Infineon SLB 9665TT2.0.
It says "SLB9665TT20" on the chip package.

These characters are also written on the package. They mean nothing to
me, but maybe they can be used to identify the hardware better:
G1946KIV
51ZA947148IA1
(It's extremely difficult to tell I from 1 though.)

> and look
> for it in the kernel sources at 
> https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/char/hw_random

In that directory I don't see anything that looks relevant.

The identifier "tpm-rng-0" comes from tpm_add_hwrng in
drivers/char/tpm/tpm-chip.c, which is still there:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/drivers/char/tpm/tpm-chip.c?h=v6.1=830b3c68c1fb1e9176028d02ef86f3cf76aa2476#n517

Other functions in the same source file create /dev/tpm0, and it looks
like the random number generator should get registered together with
the TPM. It's conditional on CONFIG_HW_RANDOM_TPM. Where can I check
the value of that option?

Thanks for the reply. I tried debian di too but wasn't successful in that

The problem is out of my range of experience and probably out of the

To improve your chances for helpful replies you should give them tangible

- The possibile configuration of the installer,
- the commands used to bring it into the directory tree which later
  becomes the ISO content,
- the exact error messages you get from the attempt to use the installer.

I agree that the patch looks ok, but I remember being hit by a kernel
change that inadvertently changed the behavior on other systems too
(ECC RAM background scrubbing), but nobody really noticed because it
was not in much use.

I suspect that the case of having an external TPM on an AMD system is
such an unusual case, and I couldn't trace exactly where that patch
checked the AMD string, so perhaps it's picking up the AMD string
earlier on, and decides to disable all TPM on the AMD system. At least
the timing of the problem and the patch is suspicious.
