Systemd 249 release candidate includes better support for immutable OSes and provisioning images

NullNix

What? sysv init scripts, both as originally implemented on sysv and as now present on (non-systemd) Linux distros are an almost wholly undocumented nightmare of barely-commented shell scripts rife with poor interactions and no error handling whatsoever. Even BSD single-rc-file was better: at least you could have conditionals that crossed multiple services easily.

sysv init scripts are a total mess and clearly crocked together from whatever pieces lay to hand at the time. No design was involved, and they're as far removed from the clean design of the Unix philosophy as the Windows kernel was.

I might not like systemd a great deal, but that doesn't mean I'm willing to engage in obvious lies to attack it. There are good reasons to dislike systemd. This is not one.

Re: Thinks I like about systemd

... why on earth are you editing things in /usr/lib and expecting them *not* to get changed by upgrades? That's got disaster written all over it, and has on every distro from Slackware on. Mess with /usr at your peril: it belongs to the distro's package manager. /etc is yours, as is /usr/local, but /usr is the distro's.

systemd has a whole scheme for letting you make changes like this and have them persist: copy /usr/lib/tmpfiles.d/tmp.conf to /etc/tmpfles.d/tmp.conf and edit that: those changes will override distro changes and will not be overridden by upgrades. This is the same for every single configuration file in systemd, and is spreading to other applications because it's such a good idea.

Linux laptop biz System76 makes its first foray into the mechanical keyboard world with dinky, hackable Launch

NullNix

Ergonomic is a different price world thought

Of course, Maltron can basically charge what they like, because their customers are a captive market: they buy because they have to, because they're escaping a world of non-metaphorical pain. Well, OK, they could also buy a Kinesis if they didn't mind it wearing out in three years, but if you want a contoured keyboard that'll last a decade or so there is really only one choice.

I mean... all these firmware-updatable hackable keyboards look really nice to me and I'd be in the market for one in a shot, *but* it'd need to have Maltron/Kinesis's contouring, or for me it's not a keyboard, it's a portable agony device I can't use for more than five minutes at a stretch. And oddly almost all these keyboards are flat, flat, flat. Some of them have interesting key layouts, but still flat, flat, flat. I guess it's cheaper to make things that are flat. Shame the human hand isn't really bult for it...

Re: Follow the money

Microsoft is also one of the biggest Linux-using companies in the world, and its largest single cash cow these days, Azure, runs more Linux instances than Windows.

Microsoft attacking Linux would be shooting itself in the financial foot. This is a thing MS has never been accused of, therefore they aren't doing it. (The same thing applies to Oracle, which maintains its own Linux distro and values the ability to hack at the OS as needed. I should know, I work on it. Obvious disclaimers regarding not speaking for Oracle, having no actual idea what our lawyers are up to etc apply. I'd be extremely surprised if they were up to *this*, but of course I could be wrong.)

Linus Torvalds went six days without electricity, swears smaller 5.12 kernel is co-incidental

That's not what LTO does

No, it slows the compiler down (quite a lot actually). It can make for better compiler *optimization*, i.e. better *runtime* performance. (It can also make for larger binaries and worse runtime performance due to increased icache bloat, though this is somewhat rarer than it used to be.)

Linux 5.10 to make Year 2038 problem the Year 2486 problem

With the release of glibc 2.33 (install with care, I found several bugs and the fixes haven't hit the release branch quite yet), it has now trickled down! This has of course instantly broken OpenSSH because it didn't have all the necessary syscalls in its seccomp filter list... (patch submitted).

Re: Linux kernel

Can't do that. Real users might have used touch to set file times to any date in the currently-valid range, so we have to expand the range in a compatible fashion, not just slide it along. (Sure, maybe you could say "bugger any users doing such crazy things", but that's the difference between a hobby filesystem and a bulletproof one. :) )

There are also (mostly-invisible) timestamps in places like the quota format that needed handling (that one was handled by reducing its precision by a factor of four, quadrupling its range with almost certainly zero visible impact on any users ever).

Re: Glad to see the legacy of Silicon Graphics living on

Um... Darrick has been an XFS hacker at Oracle for over five years now. If nearly a thousand commits aren't enough to leach this of its irony, I don't know what is.

NullNix

64-bit time_t on 32-bit platforms is not a thing which has been around for "ages": indeed the user interface (well, programmer interface, like -D_FILE_OFFSET_BITS) for 64-bit time_t on 32-bit was only finalized earlier this year and has basically not trickled out to anyone yet.

The major advantage of this fix is that it can be applied to existing filesystems with a single traversal over the inodes to fix them up. Going to true 64-bit time_t would require a mkfs (which means most systems would never do it).

Microsoft delays disabling Basic Authentication for several Exchange Online protocols 'until further notice'

NullNix

Re: Modern authentication is not a standard

So... all of a sudden your email (possibly automated) stops working unless you log into a browser and tweak the password your automated systems are using on a frequent basis?

This sounds *terribly* impractical.

Fortunately, it's not actually quite that bad: if it works like other oauth2 implementations, you can get new tokens via a fairly simple curl call, i.e. automatically. You don't need a full web browser, JavaScript or any of that crap (but then again since you can do this automatically I'm not sure what actual security it brings). It's just that every single client needs changing, and with some, like getmail, not even up to migrating away from Python 2, this might be a fairly long wait for the "long tail". And I bet a bunch of MS's own employees are using said long tail of clients... hence the stay of execution.

How do you fix a problem like open-source security? Google has an idea, though constraints may not go down well

NullNix

That's not what they meant when they said "unilateral", though, is it? The same section that talks about unilaterality also talks about all changes needing review, which *is* a good thing and isn't done remotely enough. Many of the projects cited are exceptions to this rule and do have someone not the author review every change: ffmpeg, for example.

Google aren't saying "these projects can't change without checking with us". They're saying "these projects are security-critical so more than one pair of eyes should look at all changes". Which is, well, good. Also a bit pie in the sky, I fear... :/

Passwords begone: GitHub will ban them next year for authenticating Git operations

NullNix

Re: A self-defeating approach?

It's commonplace. Most banks have *ancient* systems, and this is just one of many ways that shows.

If you want ridiculous, until last year the Coventry had a scheme where you had an eight-char password, uppercase alphanumerics only, changeable on request -- they posted you a form with eight boxes in it which you filled out and posted back, and then a few days later the password was changed. This was obviously grossly insecure so they pasted other security challenges over the top of it over time (and lately have replaced it entirely).

I bet this is because the password in question was an actual mainframe account password of some sort, changeable only from an operator console. It had that smell. (This year, they changed to allowing really long passwords, and better yet passwords with no stupid restrictions on what characters must be present, so I can just use the result of a yubikey's HMAC-SHA1 challenge-response as the password. Finally.)

NullNix

I'd bet that SSH keys will stick around, simply because they are ubiquitous in git usage and definitely not insecure -- but I suspect they'll start encouraging "sk"-format keys stored on U2F hardware tokens sooner or later, to prevent attackers stealing keys off client disks or out of client memory. (SK keys are new in OpenSSH 8.2+: it's the only hardware token mechanism I've ever found to be in any way usable. As long as both client and server are new enough -- a requirement, since this is a new key type -- I've found it as reliable as ordinary on-disk keys, something I could never have said of the old CCID-backed PIV or GPG-based nightmares.)

Re: Wang Care

Not just American companies. None other than the great Jack Vance, perhaps one of the finest wordsmiths then alive, wrote a book titled _Servants of the Wankh_, silent h and all. Admittedly, he wanted the book's title to be different, but the Wankh *were* a pivotal species in the book and he definitely didn't see anything wrong with their name. Many years later he renamed them to the 'Wannek' after being told what 'wank' meant in Britain.

If Vance didn't know... it's safe to say that next to nobody in the US did other than immigrants from countries speaking British English variants, at least not a few decades back.

It's a hell of a lot more work than it would otherwise be (and I can say this as someone who's been on both sides of that fence, both throwing code over the wall in a project my then bosses didn't allow me to open, and trying to integrate another such project with a larger system, which was much like trying to get blood out of a stone only less pleasant).

Linus Torvalds hails 'historic' Linux 5.10 for ditching defunct addressing artefact

NullNix

But then what was the thing being "made redundant by chipmakers"? As far as I can tell the only possible answer to this is "nothing": segment overrides still exist and still work just as well as they did last year. This change is not being implemented because of changes from "chipmakers" (Intel? AMD? the RISC-V Foundation? At this point it could be anyone).

The article is more than half nonsense.

NullNix

But in that case the article makes no sense! Linux never *used* 286 protected mode: 286 protected mode is not "being removed by chipmakers" but rather (depending on your viewpoint) either is still here

or ceased to exist as soon as the 386 came along (386 protected mode is a strict superset except for 286 LOADALL, which was never documented). 386 protected mode is also not being removed, not for a very long time. Segment prefix overrides, ditto (heck, gas just had a bug fixed with regard to segment override printing), though many overrides do nothing in long mode.

Regardless, Linux never worked on the 286 in any case.

So... nothing has been "made redundant by chipmakers", this change has little or nothing to do with the 286 (on which %fs never existed, so set_fs obviously never worked there even back in the days when it used %fs)... and set_fs being removed is a purely kernel-internal thing that has no relationship with anything being made obsolete by Intel... or whichever "chipmaker" is being vaguely alluded to here. It stopped using the %fs register ages ago, but that doesn't mean %fs has been removed, just that this particular use for it has gone away. (It is in the ABI. It cannot be removed without breaking every program that uses thread-local storage. %fs is forever.)

My impression of an article written by someone who didn't know what he was talking about persists.

Re: RISC OS did this in the 1980s

The 64-bit time_t stuff has been landing for many releases now, and time_t has always been 64-bit on 64-bit platforms. This is all filesystem work, which is much harder because the data is persistent and people like not to lose it. In this case, XFS format v5 is gaining 64-bit stuff for filesystem timestamps, in a backwardly-compatible way that does not require a mkfs: that's all. (Bear in mind that the original XFS is a child of the early 90s, so not all that much newer than RISC OS.)

NullNix

This article almost entirely wrong, to the point that I wonder whether the author has done any research whatsoever or knows anything at all about the x86, even the names of the registers in its register file.

%fs and %gs originated with the 386, not the 286, as ten seconds research would show. As Linus himself said in the very announcement you link to, the kernel hasn't used %fs to point to user memory since sometime before the start of git history, and it certainly hasn't been 'made redundant by chipmakers': %fs and %gs are the only two segment registers that are still useful in x86_64 long mode, and indeed the kernel still uses them, as does userspace.

It's just that the kernel no longer uses a function call that happens to still be called set_fs() (for purely historical reasons) to address userspace memory while in kernel mode, that's all. (Instead this security-sensitive thing is now done at the lowest possible level, in the smallest possible number of places, in the access primitives themselves, not scattered across all the individual drivers that do the accesses.)

Re: That's downright cheap!

I didn't say you couldn't get mechanical keyboards: I said they weren't going to be cheap. This is not a bad thing, as you still save money in the end because the thing'll take many times longer to wear out than a cheap keyboard would. It's Vimes's "Boots" theory of socio-economic unfairness applied to keyboards.

(Ergonomic *everything* is much more expensive. It doesn't matter: my trusty Maltron might cost a lot but I bought it in the early 2000s, have used it to the exclusion of everything else, and it still works. The keyswitches wore out once and were replaced: doing the replacement cost about £70, and was worth every penny. It *is* important that you have a method in place to avoid the possibility of ever spilling anything on the keyboard!)

NullNix

That's downright cheap!

You can't get *decent* mechanical keyboards (the sort that'll live for a decade or more) for much less than this is going for. Ergonomic ones routinely cost two or three times as much.

It looks good to me (though I'm not interested in it because RSI means I'm forced to use ludicrously expensive ergonomic keyboards -- and, because spending that much money is a sort of mind control, I'm forced to evangelise them at every possible opportunity too QWERTY SUCKS even when it makes no sense and is SPLIT KEYBOARDS FOREVER obviously shoehorned into the FNORD conversation.)

Linux kernel maintainers tear Paragon a new one after firm submits read-write NTFS driver in 27,000 lines of code

NullNix

Re: So?

> 27,000 lines of code isn't really that much, its a substantial chunk but it should break down into components that can be individually reviewed and tested.

Yes, and doing that was Paragon's job, not the reviewer's. It's not like it's hard to split a huge ugly pile of work into neat commits. Picking an example totally at random because it's one I'm familiar with: it's not quite as big perhaps, but I did that for 10,000-odd lines of work just last month, originally in perhaps 250 completely unreviewable use-git-as-a-backup-system commits with commit log messages reading things like "fix the fix" and "giant pile of unsplit work" (https://sourceware.org/pipermail/binutils/2020-June/112012.html). It took perhaps two days to split up six months or so of work.

If you can't be bothered to do even that much to make your code easier to follow, I don't think it says much about your likely long-term commitment to the contribution or about your consideration for the maintainer you're dumping this stuff on.

This NSA, FBI security advisory has four words you never want to see together: Fancy Bear Linux rootkit

Re: Get Root?

Not that I can see, which makes this whole thing a panic over nothing. Yes, if you run malicious code as root it *can* persist itself. This is nothing new. Don't run malicious code as root. (And keep your machine as safe as possible from holes that allow unprivileged users or network daemons to escalate to root.)

(Secure Boot only saves the boot process and firmware, anyway -- it won't save you from things that persist in network card firmware, disk controller firmware etc. Like, oh, the NSA uses, and since they do I'm sure the Russians can deploy that real soon now as well. Again, just don't run it as root and you're safe.)

NullNix

Re: Alternatives?

Yeah. I will admit I don't understand people who say they do a lot of typing and then insist on buying a cheap keyboard. If you do a lot of typing the keyboard is critical equipment, and it's critical stuff that your hands hit a lot. That means it's also health-critical. Why would you *not* spend a reasonable sum on something like that? Why aim for the cheapest thing you possibly can? I am mystified.

Also... if you buy a keyboard with good switches -- which means expense, I'm sorry -- you can expect it to not fail for decades. The Cherry keyswitches I'm using in the keyboard here did need replacement, but that was after *twenty years of continuous use*, and the thing about a keyboard that costs a lot is that if the vendor is still going after that long they'll probably be happy to replace the switches for you for less than the cost of a replacement keyboard.

Cheaper keyboards wear out much faster, and are nastier to type on as well.

Oh come on she wasn't selected on that basis. She was selected on the basis of being pro-Brexit, just like everyone else in Cabinet. She just happens to combine that with being so right-wing that she makes Rees-Mogg look like Neil Kinnock, so short-tempered that she makes our recently-ex Speaker look like the kindest person who ever was, and "as thick as mince" (and that was from one of her *supporters*, off the record).

However, she didn't manage the biggest own-goal of this Cabinet so far, infecting half of it with SARS-CoV-2. That was probably Nadine Dorries' doing -- and that's another sign of a terrible low-competence cabinet: why the hell is she a health minister, even a lowly one? her only interest in public health historically has been to use every possible opportunity to try to ban abortion, even though doing so is *massively* unpopular in the UK outside Northern Ireland and would get any government that tried to do it turned out on its ear. Answer: she's pro-Brexit and they long ago run out of *competent* pro-Brexiteers, given that in order to be an enthusiastic Brexiteer you more or less have to be incapable of foresight or know nothing whatsoever about international trade while imagining that you know a lot.

Re: Read the PDFs

A horrific disease happened to it.

Re: And use food delivery services where you can.”

That's OK: every single UK supermarket has buckled under the load, and is either not accepting new registrations (Sainsburys) or hanging when you try to do it (Waitrose) or not allowing you to buy anything (Tesco) or simply not bothering with a website any more (Ocado). So I guess it's go out and try to pick what food there is off the nearly-bare shelves.

Food markets *are* still open, so those of us lucky enough to live in market towns can still use those as our primary fresh food supply. They seem to be a bit less stricken by panic-buying than the supermarkets.

Without Karl I would be crippled. (But not because of Subversion: because he's one of the very few users of the Maltron keyboard, and back when my RSI started to bite I asked him if it was any good. He said it was. He was quite thoroughly correct.)

One thing Karl has is good taste. The interior of Subversion shows that: it's lovely, enormously extensible, and far more cleanly architected than the interior of Git. However... most of that complexity, in hindsight, is epicyclic: you don't need it if you start from the right place, and in hindsight, Git started from the right place, and Subversion didn't. Of course, Subversion *couldn't* start from the right place, given the design goals, and also one can hardly fault Karl or anyone for not having the insight that led to Git in the first place. You cannot force insights.

Re: It's all very fascinating

You always have at least two keys (in different places), and register both of them with everything. If you don't, you will sooner or later be regretting it: USB devices don't last forever even if you don't carry them on your keyring. Any site that doesn't allow registration of multiple tokens against a single user identity is arguably broken: don't use it for 2FA unless it provides some sort of fallback (and even then, the fallback serves as a lower-security way in, reducing the security benefits of the key).

(Currently, I have four, but that's more because I lost one and then found it long after, and my then-backup didn't have NFC and I found I needed NFC on at least two of them, than because having that many keys is actually sane.)
