The commit message summarizes why this makes sense,

Splitting this code into a separate binary ensures that the crucial pre-authentication attack surface has an entirely disjoint address space from the code used for the rest of the connection. It also yields a small runtime memory saving as the authentication code will be unloaded after thhe authentication phase completes.

The code is in snapshots as we type.

Omar Polo (op@) has announced the release of version 7.6.0p0 of OpenSMTPD.

The changes (including the table protocol change on which we reported earlier) are:

See the release announcement for full details.

So the diffstat looks a bit odd, because one of the fixes here caused the UTF tables to be regenerated, and an effective one-liner change turned into 6703 lines of diff.

But if you ignore that effect, everything looks normal.

At Kangrejos, Gary Guo wanted to discuss three problems with the way Rust and C code in the kernel interact: mismatched types, too many type casts, and the overhead of helper functions. To fix the first two problems, Guo proposed changing the way the kernel maps C types into Rust types. The last problem was a bit trickier, but he has a clever workaround for that, based on tricking the compiler into inlining the helper functions across language boundaries.

First, let me paraphrase something from my LiveJournal profile: These posts are my own, and in particular do not necessarily reflect my employer's positions, strategies, or opinions.

With that said, some say that the current geopolitical outlook is grim.  And far be it from me to minimize the present-day geopolitical problems, nor am I at all interested in comparing them to their counterparts in the "good old days".  But neither do I wish to obsess on these problems.  I will instead call attention to a few instances of global cooperation, current and past.

Last month, NASA's oldest active astronaut traveled to Kazakhstan's Baikonur Cosmodrome, entered a Soyuz capsule atop a Roscosmos rocket and flew to the International Space Station. For me, this is especially inspiring: If he can do that at age 69, I should certainly be able to continue doing my much less demanding job for many years to come.

Some decades ago, during the Cold War, I purchased an English translation of Gradshteyn's and Ryzhik's classic "Table of Integrals, Series, and Products".  Although computer-algebra systems have largely replaced this book, I have used it within the past few years and I used it heavily in the 1980s and early 1990s.  Thus, along with many others, I am indebted to the longstanding Russian tradition of excellence in mathematics.

So just this past month, I was happy to receive hard copies of "Параллельное программирование – так ли это сложно?", which is a Russian translation of "Is Parallel Programming Hard, And, If So, What Can You Do About It?"  I would like to think that this might be a down payment on my aforementioned debt.

Many other countries have also made many excellent contributions to mathematics, science, and technology.  For example, the smartphone that I used hails from South Korea.  And earlier this year, SeongJae (SJ) Park completed a Korean translation of the Second Edition of "Is Parallel Programming Hard, And, If So, What Can You Do About It?"

Returning to rocketry, China started working with rockets in the 1200s, if not earlier, and has made a great deal of more recent progress in a wide variety of fields.  And rumor has it that a Chinese translation of the Second Edition will be appearing shortly.

So if you tried reading this book, but the English got in the way, you now have two other options and hopefully soon a third!  But what if you want a fourth option?  Then you, too, can do a translation!  Just send me a translated chapter and I will add it to the list in the book's FAQ.txt file.

Version 24.10 of the Ubuntu distribution is out. This release includes GNOME 47, Linux 6.11, security enhancements for managing Personal Package Archives (PPAs), experimental security controls for Snap packages, and more.
