There appeared a "shadow" border around the window containing Thunderbird, so I reverted to the previous version. Other than that, I didn't use it long. Change for the sake of change. No real improvements, IMHO.

It's a major change. Since this is for current I couldn't understand not to test that...

I even would say : last KDE + new thunderbird could be a good milestone for a 15.1 release

cwizardone · 07-14-2023, 04:32 PM

When Thunderbird-115.1 becomes available, I'll take another look.

Hey folks! It's time to acknowledge another one of those milestones... 30 (!)
years since I made the post linked below announcing Slackware's first stable
release after months of beta testing. Thanks to all of our dedicated
contributors, loyal users, and those who have helped us to keep the lights on
here. It's really been a remarkable journey that I couldn't have anticipated
starting out back in 1993. Cheers! :-)

  OK, usually I won't use rc versions even in -current, but in this case I'm
  going to. Some time ago my desktop machine with RS880 / Radeon HD 4290
  graphics on the motherboard began acting up with the screen going black
  for a few seconds before returning. This after an hour or so of uptime,
  usually, then becoming more frequent with more uptime. Eventually I'd lose
  mouse and/or keyboard too, and have to reboot. Here's a couple of errors
  from dmesg:
    [ 9942.677675] [drm:r600_ib_test [radeon]] *ERROR* radeon: fence wait
                   timed out.
    [ 9942.677741] [drm:radeon_ib_ring_tests [radeon]] *ERROR* radeon: failed
                   testing IB on GFX ring (-110).
  I also noticed that the backtrace started with ttm_bo_release, and seeing
  this in recent kernel patches had been chalking this up to a kernel bug.
  I *still* think it could be, and there are a bunch of kernel patches coming
  soon to -stable from Alex Deucher that could address the underlying causes
  (not for 6.1.39 though, unfortunately). Anyway, I'd recently figured out
  that reverting Mesa sufficiently made the issue go away. And now it seems
  this 23.2.0 release candidate also fixes the issue.
  Yes, I could go search for the commits to cherry-pick, but we'll be moving
  to mesa-23.2.0 when it's released, so we might as well start testing now.

When I moved to "amdgpu" module from "radeon" (due to Mesa update requirement), I started seeing these alot. Maybe someone recalls me posting about it. A number of people have posted about it on various dev forums (search ttm_bo_release or amdgpu_bo_unref). Regardless, there's no solution. Mostly I gave up on it.

Now, I have 12 days uptime, mesa-23.1.3, and kernel 6.4.1. So far so good except for some screen tearing.

n/dhcpcd-10.0.2-x86_64-1.txz:  Upgraded.
n/openssh-9.3p2-x86_64-1.txz:  Upgraded.
  This update fixes a security issue:
  ssh-agent(1) in OpenSSH between and 5.5 and 9.3p1 (inclusive): remote code
  execution relating to PKCS#11 providers.
  The PKCS#11 support ssh-agent(1) could be abused to achieve remote code
  execution via a forwarded agent socket if the following conditions are met:
  * Exploitation requires the presence of specific libraries on the victim
    system.
  * Remote exploitation requires that the agent was forwarded to an
    attacker-controlled system.
  Exploitation can also be prevented by starting ssh-agent(1) with an empty
  PKCS#11/FIDO allowlist (ssh-agent -P '') or by configuring an allowlist that
  contains only specific provider libraries.
  This vulnerability was discovered and demonstrated to be exploitable by the
  Qualys Security Advisory team.
  Potentially-incompatible changes:
  * ssh-agent(8): the agent will now refuse requests to load PKCS#11 modules
  issued by remote clients by default. A flag has been added to restore the
  previous behaviour: "-Oallow-remote-pkcs11".
  For more information, see:
    https://www.openssh.com/txt/release-9.3p2

  (* Security fix *)
n/samba-4.18.5-x86_64-1.txz:  Upgraded.
  This update fixes security issues:
  When winbind is used for NTLM authentication, a maliciously crafted request
  can trigger an out-of-bounds read in winbind and possibly crash it.
  SMB2 packet signing is not enforced if an admin configured
  "server signing = required" or for SMB2 connections to Domain Controllers
  where SMB2 packet signing is mandatory.
  An infinite loop bug in Samba's mdssvc RPC service for Spotlight can be
  triggered by an unauthenticated attacker by issuing a malformed RPC request.
  Missing type validation in Samba's mdssvc RPC service for Spotlight can be
  used by an unauthenticated attacker to trigger a process crash in a shared
  RPC mdssvc worker process.
  As part of the Spotlight protocol Samba discloses the server-side absolute
  path of shares and files and directories in search results.

a/kernel-firmware-20230724_59fbffa-noarch-1.txz:  Upgraded.
  AMD microcode updated to fix a use-after-free in AMD Zen2 processors.
  From Tavis Ormandy's annoucement of the issue:
    "The practical result here is that you can spy on the registers of other
    processes. No system calls or privileges are required.
    It works across virtual machines and affects all operating systems.
    I have written a poc for this issue that's fast enough to reconstruct
    keys and passwords as users log in."
