YES! KDE6 landed in OpenBSD -current

Rafael Sadowski (rsadowski@) writes in his most recent blog entry on KDE6 on OpenBSD, and goes on to say

We are currently in an excellent phase ahead of the upcoming OpenBSD release 7.6, which gives us plenty time to thoroughly test KDE Plasma 6. My goal is to make sure it works well and is stable for everyone.

Also worth noting is some still in progress work,

Stay tuned for more updates as we progress towards the integration of KDE Plasma 6 into OpenBSD 7.6.

But don't just take our word for it, read the whole thing, KDE6 on OpenBSD over at Rafael's blog. There you will find detailed descriptions of how to perform the upgrade, and a video of the important points.

With the following commit, Damien Miller (djm@) commenced the process of splitting sshd(8) into multiple binaries:

Is the classical TCP congestion control mechanism known as Nagle's algorithm (RFC 896 - Congestion Control) headed for the scrap heap of history?

A recent post on tech@ titled Add sysctl to disable Nagle's algorithm (RFC 896 - Congestion Control) from Job Snijders (job@) with a patch to implement the disabling sysctl indicates that some at least think that deprecation is in order.

The message leads in,

Dear all,

Back in the early 1980s, a suggestion was put forward how to improve TCP
congestion control, also known as "Nagle's algorithm". See RFC 896.

Nagle's algorithm can cause consecutive small packets from userland
applications to be coalesced into a single TCP packet. This happens at
the cost of an increase in latency: the sender is locally queuing up
data until it either receives an acknowledgement from the remote side or
sufficient additional data piled up to send a full-sized segment.

The LibreSSL project has announced the release of [bugfix] version 3.9.2 of the software:

We have released LibreSSL 3.9.2, which will be arriving in the
LibreSSL directory of your local OpenBSD mirror soon.

It includes the following change from LibreSSL 3.9.1:

 * Bugfixes
   - OpenBSD 7.5 errata 003. A missing bounds check could lead to a crash
     due to dereferencing a zero-sized allocation.

The LibreSSL project continues improvement of the codebase to reflect modern,
safe programming practices. We welcome feedback and improvements from the
broader community. Thanks to all of the contributors who helped make this
release possible.

Version 0.99 of Game of Trees has been released (and the port updated).

* got 0.99; 2024-05-05
  see git repository history for per-change authorship information
- make 'got fetch' work with URLs which refer to $HOME via a tilde: ~user
- replace strftime %G-%m-%d with %F to prevent 2024-12-30 -> 2025-12-30
- fix spurious errors from got-fetch-http when server has no more data to send
- prevent gotd notification process from exiting due to EPIPE
- fix I/O hangs with TLS in got-notify-http
- document http and https protocol support in got.conf(5), too
- fix an fd leak in gotd's notify process causing endless CPU spin
- back out got stage -R option addition; deemed too inconvenient in practice
- fix got-fetch-http GET request URL; add leading slash and avoid double slashes
- allow custom GOT_TEST_HTTP_PORT when running regression tests
- gotwebd: add magic ".git" handling; try foo.git if repository foo is not found
- expose authenticated gotd user account in HTTP notifications
- gotd.conf(5) HTTP/JSON documentation fixes
- fix endless loop upon Ctrl-D (EOF) input during got stage/unstage/revert -p
- make gotd notifications work when 'git push' is used instead of 'got send'
- make got stage -p behave the same way in interactive and -F modes for 'q'
- fix lingering gotd processes from clients closing connections early
- regress: prevent spurious failure of gotd test_clone_basic_access_denied
- fix an issue where 'git fetch' would error or hang against gotd
- use polling read in got_pkt_readn() to avoid endless hangs in gotsh

And we, too, are curious what the next version number will be :)

Regular readers will be aware that OpenBSD ships with its own mail server implementation, OpenSMTPD, in its base system.

In a recent message to the tech@ mailing list, Omar Polo (op@) asked for comments or oks for a patches implementing a change of table protocols. A little later, Gilles Chehade (gilles@) posted to the misc@opensmtpd.org mailing list with the backstory for this change.

The message follows in full below (apparently the otherwise fine marc.info archive site no longer archives the list):

Subject: smtpd: change the table protocol

Hello,

This is a copy of a mail I sent to OpenBSD hackers a few days ago so you are aware of work
being done on OpenSMTPD by Omar Polo.

~~~

TL;DR: proposal to change table backends wire protocol to one that's closer to filters, it
       has proven to work for years now, comes with many benefits and it is a very trivial
       change that we can pull in a handful of hours:

Have you had your laptop accidentally un-hibernate while you weren't looking, leaving you with a totally drained battery?

Now OpenBSD-current has a fix for that, thanks to this commit by Klemens Nanni (kn@). The commit message reads,

The version control system gameoftrees 0.98 has been released and should soon show up in OpenBSD -current packages. An update for the -portable version will follow as well.

The main improvements in the new release are listed in the release notes as

- speed up got tag -l by caching timestamps in got_ref_cmp_tags()
- provide a macro for vi(1) path for use by -portable at compile time
- avoid a rename/stat race when gotd installs a new pack and then uses it
- make 'got ref -l' output consistent when packed references exist
- make 'got ref -l' work consistently when a reference argument is given
- add initial support for notifications to gotd(8), via email and http/json

The OpenBSD toolbox for network debugging just got better. In a recent thread on tech@ titled pfctl show fragment info, Alexander Bluhm (bluhm@) posted a patch to enable packet reassembly statistics in pfctl(8).

Several other developers joined in, and Claudio Jeker (claudio@) suggested that systat(8) should too be enhanced to display packet reassembly data in pf(4) related views.

This suggestion was well received, and the resulting code has now been committed,
