Re: [gentoo-user] Where are the AMD microcode updates for spectre?

[Volker Armin Hemmann]

Also... be prepared for a lot of trouble with intel cpu's soon...

the bigger the drive, the greater the chance of fs corruption. Just by
statistics. Better one minor partition is lost than everything.

You can disagree as much as you like, but with the size of drives and
the current error rate of consumer hard drives it is not a question of
'if' but just a matter of 'when'.

it is not so much about cow, but integrity checks all the way from the
moment the cpu spends some cycles on it. Caught some silent file
corruptions that way. Switched to ECC ram and never saw them again.

the journal does not add any data integrity benefits at all. It just

ext2 is on every system, exfat not. ext2 is very stable, tested and well
aged. exfat is some fuse something crap. New, hardly tested and unstable
as it gets.

And why use exfat if you use linux? It is just not needed at all.

so it is not turned on on x86. Not sure about amd64. IIRC it is default
on amd64, but I am not sure and too lazy to google. Just like the thread
starter.

so you got away with stupid behaviour for a while, but now reality has
caught up with you. But instead of rethinking your approach or listening
to the advise of others you insist on continuing with your broken crap.

you do stupid things and then complain that the system does not work.

Why don't you stop doing stupid things?

That said, C 1.0 blocks A 1.0 but updating to C 2.0 would solve it, does
happen, even if you do not act retarded, BUT those instances are usually
easy to solve.

Instead of letting portage hang to dry and ranting on this ml, smart
people just emerge -u C and then go on with the rest of the updates.
Wow, that was hard. I am sweating all over. Maybe I should lay down for
a while. After a long shower.

hm, back then and everytime kdbus came up on lkml the consensus was
'speed? you do it for speed? Get userspace dbus in order and the speed
argument collapses'. Pretty much everybody also voiced problems with
security (none) and the statefulness of dbus.

All problems, blissfully ignored by the kdbus bunch.

I have a 125w CPU and a R7 370 plus a shitload of HDDs and all those are
quite happily fed by a 450W PSU. A pretty old 450W BeQuiet PSU.

Go figure.

What does my 600VA UPS says about this?
27% load at the moment.

a) I know what happens if you have a bad PSU. That is why I am using
BeQuiet.

b) those 27% include the monitor and router.

b) I know how much my computer draws at full load. 300W. Absolut
maximum. All inclusive. Screen, fritzbox, powered usb hubs, computer

Mount Points
   Creating  a ZFS file system is a simple operation, so the number
of file systems per system is likely to be numerous. To cope with this, ZFS
   automatically manages mounting and unmounting file systems
without the need to edit the /etc/fstab file. All automatically managed
file sys-
   tems are mounted by ZFS at boot time.


   By  default,  file  systems are mounted under /path, where path
is the name of the file system in the ZFS namespace. Directories are created
   and destroyed as needed.


   A file system can also have a mount point set in the mountpoint
property. This directory is created as needed, and ZFS automatically  mounts
   the  file  system  when  the  zfs  mount -a command is invoked
(without editing /etc/fstab). The mountpoint property can be inherited,
so if
   pool/home has a mount point of /export/stuff, then pool/home/user
automatically inherits a mount point of /export/stuff/user.


   A file system mountpoint property of none prevents the file
system from being mounted.


   If needed, ZFS file systems can also be managed with traditional
tools (mount, umount, /etc/fstab). If a file system's mount point is set to
   legacy, ZFS makes no attempt to manage the file system, and the
administrator is responsible for mounting and unmounting the file system.

 Yeah. I don't remember what the exact error message was, other than it

 Booting from USB worked fine. Compiling while booted from USB worked
 until I chroot'ed to the failed SSD. Then a bunch of segfaults and other
 weird errors.

 I've seen this before both at home and work, where SSDs do this with no
 warning. IMO they're way too unreliable. I don't have one in my server
 or workstation at home. I had one in my server and it lasted two years
 before similar issues above. It (server SSD) was replaced with a

 Well, I sure haven't had much luck with SSDs. This will be the third one
 I've lost.

 On Wednesday I was watching my mythtv frontend when it hardlocked. Last
 time this happened the 7-year-old rust recordings drive failed. However,
 all that checked out and I found out I couldn't ssh in to the frontend
 to kill mythfrontend.

 I checked the CPU  RAM by booting via USB and it all checked out. I
 tried booting the SSD and the kernel panicked. After rebooting again, it
 started, but every command run ended with a segmentation fault.

 I decided to try flashing the drive's firmware, and that did so
 successfully. It booted right away after that with no panic, but the
 frontend decided that it couldn't find the backend any longer. I found
 this was not true, I (as root) could ping and connect via mysql using
 remote credentials.

 After another twenty minutes of fiddling around, I discovered the setUID
 root bit on /bin/ping had been removed somehow and this was preventing
 mythtv from finding its backend. At this point I restored from backup
 and then I discovered after restoring /bin/ping lost it setuid root bit
 again.

 After that I gave up (thinking what else has changed on the disk) and
 yesterday bought a new SSD, this time a SanDisk model. It was cheap and
 I hope I don't regret this in the future. So my frontend is once again
 running.

 That aside, the drive that failed is a Crucial m4. I have done some
 searching as how to run diagnostics on an SSD. This drive should still
 have eight or so months of warranty left. These drive did have a bug if
 they ran longer than 51xx hours but:

   9 Power_On_Hours  0x0032   100   100   001Old_age   Always
   -   2382

 ...there's only 2382 on this drive. It also accesses all media remotely
 through the LAN.

 Currently I'm running shred on the affected SSD. I also could run
 smartctl on the drive. Do other diagnostic tools even work on SSDs? This
 is where I'm sort of lost, I've not tried diagnostics on them. I usually
 send them back for warranty, but this time I'm curious.

  If anyone can splain what introspection does I'd be grateful.

 Alan did a fine job explaining what introspection is in general. In
 Gentoo, the introspection flag is only used by GObject based
 libraries; all the languages that natively supports introspection does
 it inconditionally, and (as far as I am aware) GObject is the only C
 object oriented library that provides introspection.

 Some years ago, you could get away without activating it, but nowadays
 is for all practical purposes mandatory. At least this is the case for
 GNOME 3; but I would not be surprised if it's also the case for
 basically any GObject based software; that covers all GTK+ 2 and 3
 applications. The instrospection infrastructure is not only used (as
 Alan mentioned) to look inside a compiled class; it's also part of
 the automatic binding generation for other programming languages used
 by all GObject libraries (or at lest that's what I understand, please
 correct me if I'm wrong). Therefore, if you use Inkscape, for example,
 you'll need introspection since Inkscape is wrote in C++ using the
 gtk-- bindings.

 In general, I would recommend not to set USE=-* (an opinion shared
 by basically all Gentoo devs and most rational people), and let the
 default use flags to do their magic. But everyone is free to break
 their systems as they please.

You believe in some urban legend you never dared to question.


 If you're concerned about somebody reading the contents of the drive
 using the standard ATA commands, then once with zeros is just fine.
 Secure erase is probably easier/faster.

 If you're concerned about somebody removing the disks from the drive
 and reading them with specialized equipment then you really want
 multiple rounds of complete overwrites with random data.  Even then
 you run the risk of relocation blocks and all that stuff, so the
 secure erase at the end is still a wise move but it may or may not
 completely do the job.

even then one time is enough. Links are below.



 If you're concerned about somebody leaving the disks in the drive but
 having access to directly manipulate the drive heads to possibly
 access data not accessible using the standard ATA commands then one
 pass is probably good enough, but I'd still use random data instead of
 zeros.  The reason is that a clever firmware (especially on an SSD)
 might not actually record zeros to the regular disk space, but instead
 just mark the block range as containing zeros, leaving the actual data
 intact.  For random data the drive has to actually store the contents
 as it cannot be represented in any more concise way.

 If I'm not in a rush I prefer to just do the multiple passes.  Why
 take a chance?

if you do it, it is your problem, but recommending something stupid is
something else altogether.


 And of course full-disk encryption is the solution to all of the
 above, as it defeats any kind of attack at the level of the drive and
 is proactive in nature.

Re: [gentoo-user] OT: Southbridge chip on laptop overheating

[Volker Armin Hemmann]

Am 08.06.2015 um 00:15 schrieb Daniel Frey:
 Hi all,

 Not really Gentoo-related (well except the overheating part - lots of
 compiling ;-) )

 I have a very old laptop. It is an LG F1 laptop (circa 2005/2006 I
 believe) about nine years old. This has a Core2 1.6GHz chip and 4GB RAM,
 even though it only sees 3GB (that should tell you it's pretty old!)

 Anyway, I noticed during my last compile-fest on my laptop (reinstalled,
 switched to systemd for testing) that a corner of the laptop is getting
 really hot. We are talking a fair bit of heat here, you can't keep it on
 your lap when it warms up.

 So I took it apart yesterday, figuring I should re-do the thermal paste.
 During this process, I discovered it's the southbridge ICH chip that's
 overheating. There's no cooler at all on this chip (the northbridge and
 CPU have heat piping), it's a bare chip.

 Now, I suspect there's not much I can do about this given it being a
 laptop and I might have to resign myself to the fact that I'm going to
 have to buy a laptop later this year/early next year.

 I am curious though, what causes this chip to overheat, and can I do
 something about it?

 I'm using lm_sensors, which doesn't provide a temperature for this
 particular chip. I've monitored processes and nothing really stands out.
 I've even tried disabling plasma, no luck.

 Dan



are you sure it is overheating and not operating within spec?

A lot of laptops have 'hot spots'.

 I also think so.

 I have

 Hi all,
  I've been using Firefox for ages and something struck me recently as a
 bit odd. In the Windows version, if I click up into the address or
 search boxes, the existing contents are highlighted and if I begin
 typing, the existing text is deleted and what I'm typing becomes the
 contents. On the Linux version, under KDE, it doesn't. I have to click
 into the appropriate edit box, highlight the contents and start typing
 or hit either home/end and then start deleting before typing my new URL.
 If, for example, the existing text happens to be a google search string,
 this can be quite a bit of text to delete.

  So my question, I suppose, is multipart:

 1) Is this by design? Is this the normal behaviour?

 2) Have I set a USE flag wrong somewhere that causes this behaviour?

 3) How do people get around the problem I mentioned above regarding long
 URL's, such as a Google search results?

  Any thoughts, greatly appreciated,

 Hi Andrew,

 You might be interested in these settings (from about:config):

 browser.urlbar.clickSelectsAll
 browser.urlbar.doubleClickSelectsAll

 You can configure what happens when you click in the address bar.

 I have no idea why the defaults on win/linux are different, though,

 Cheers,

maybe because in linux selecting = copying. So if you select with a
simple click you might overwrite the contents of the clipboard = highly
annoying.

 No. Optimizer paths may be very unobvious, i.e. I'll not be

 instructions for int code.

 The kernel uses -O2 and several -march variants (e.g. -march=core2).
 Several other options are used to prevent GCC from generating
 unsuitable code.

 Specifying another -march variant does not affect the optimizer
 though. It only affects the code generator. If you don't modify the
 other CFLAGS and only change -march, you will not get FP instructions
 unless you use FP in the code.

 Also, I'd be very interested to see *any* optimization that would
 somehow transform integer code to FP code (note that SIMD is not FP
 and is perfectly fine in the kernel.) In fact, optimizers tend to
 transform FP into SIMD, at least on x86 (and other architectures that
 have fast SIMD instructions.) If I inspect the generated assembly from
 GCC or Clang, I cannot find FP anywhere, even for code using float
 and double operations. They get converted to SIMD on modern CPUs
 (unless you specify a compiler flag that tells it to use the FPU, for
 example if you need 80-bit extended precision, which is supported by
 the x86 FPU.)

saves time in case no
more than one thread uses these registers. The lazy saving scheme is not
supported in
kernel mode. Any device driver that attempts to use these registers
improperly will cause an
exception that will probably make the system crash. A device driver that
needs to use vector
registers must first save these registers by calling the function
kernel_fpu_begin() and
restore the registers by calling kernel_fpu_end() before returning or
sleeping. These
functions also prevent pre-emptive interruption of the device driver
which could otherwise
mess up the registers. kernel_fpu_begin() saves all floating point
registers and vector
registers if available.
There is no red zone in 64-bit Linux kernel mode.
The programmer should be aware of these restrictions if calling any
other library than the
system kernel libraries from a device driver.

 Also, I'd be very interested to see *any* optimization that would

 transform FP into SIMD, at least on x86 (and other architectures that
 have fast SIMD instructions.) If I inspect the generated assembly from
 GCC or Clang, I cannot find FP anywhere, even for code using float
 and double operations. They get converted to SIMD on modern CPUs
 (unless you specify a compiler flag that tells it to use the FPU, for
 example if you need 80-bit extended precision, which is supported by
 the x86 FPU.)

 Not sure why you think that. The kernel crypto routines are full of

 But -march is not going to introduce that

 If you are using systemd, there are a few modules that it always loads
 (ipv6, autofs4, stuff like that). Everything else is loaded
 automatically, by udevm, as-needed.

 My guess (but I could be wrong); you are using an initramfs, and
 didn't included the modules in it. In that case, the modules are not
 loaded because they are not available.

 I have no idea if OpenRC tries to load modules.

yes it does. You poor bunny. All those years using openrc all but

  I wonder if that's accurate.  I know that OpenRC also uses cgroups

 According to [1]:

 
 # If you have cgroups turned on in your kernel, this switch controls

 [...]
 # Set this to YES if yu want all of the processes in a service's cgroup

 # This should not be set globally because it kills all of the service's
 # child processes, and most of the time this is undesirable. Please set
 # it in /etc/conf.d/service.
 # To perform this cleanup manually for a stopped service, you can
 # execute cgroup_cleanup with /etc/init.d/service cgroup_cleanup or
 # rc-service service cgroup_cleanup.
 # rc_cgroup_cleanup=NO
 

 So it's available if you have cgroups turned on, and then you need to
 set it up globally (which is not recommended), or by service. That
 wasn't available when I stopped using OpenRC; but then again, that was
 almost five years ago.

 Is nice to see OpenRC catching up to systemd.

 Well, the old answer would be that you need to use sudo to run it, as

 I suspect that the new answer is that with appropriate

 sitting at a physical console to shut down the system, or any
 logged-in user if you prefer.  However, I haven't actually set that up
 myself.
 logind does that for you automagically™. The first seat has the rights to
 poweroff or reboot the machine, and it can differentiate between local and
 remote logins. You can check if your user session has the permissions to
 poweroff/reboot via dbus:

 $ gdbus call --system --dest org.freedesktop.login1 --object-path
 /org/freedesktop/login1 --method org.freedesktop.login1.Manager.CanPowerOff
 ('yes',)

 $ gdbus call --system --dest org.freedesktop.login1 --object-path
 /org/freedesktop/login1 --method org.freedesktop.login1.Manager.CanReboot
 ('yes',)

 But you need systemd to use logind1. There has been some attempts to
 reimplement logind outside systemd, but I'm not sure how advanced they are.

 This kind of problems were one of the reasons for creating logind.

 and dump people keep talking nonsencely that sysvinit is enough while it

 Yesterday I installed 4GB more of RAM in this machine for a total of 8GB, and

 I let memtest86+ run overnight and it found zero memory errors. Today I
 exchanged the new RAM anyway and got a different brand this time, and
 that fixed the problem.

 My question is why didn't memtest86+ find any errors?  Could it be that the
 first RAM I bought was actually okay but this machine didn't like it for some
 reason?  Both were DDR3/1333MHz, just from different manufacturers.




Since this was not mentioned yet:

Maybe because the ram was not faulty at all.

Maybe it really operated in the range of allowed tolerances - and those
were never crossed with memtest as a very light system load.

But with an OS booted, the CPU, graphics solution, harddisks all sucking
power like mad, your mainboard or PSU might not be able to deliver as
stable currents as the specifications demand. Some memory is more

 I'd say the problem is not about the devs themselves causing conflicts
 but the environment and frame devs are working in the current workflow.
 Everybody look baffled with the current way of doing things in Gentoo.

 I agree with hasukel that the distributed Gentoo as proposed today is
 a wrong answer.  Not that the issues raised are not valid. They do.

 Also, I agree with hasukel that the main problem is about having a
 correct distributed model. Posting on bugzilla for ebuilds updates or
 new ebuilds is seriously damaging when almost every where else it is
 just about sending your git patches. Becoming an official Gentoo dev is
 not a solution either due to the recruiting process.

 As you say, official devs can work on whatever they like and their
 contributions will likely hit the users at some point while at the same
 time occasional devs are asked to work with old tools like bugzilla. So
 yes, the whole review process is broken and the contribution process is
 broken too.

 About that, there's no other way than break the whole recruiting process
 and change of tools. Have your core team handle git repositories and let
 others request pull or send patches like almost all the other open
 source softwares in the world. Let's exploit the anarchy and openness
 instead of partitionning things into devs/non-devs or main-tree/overlays.


 Back to the original request. Here is how starts the distributed
 Gentoo model:

   Imagine you would say I like gentoo, but I don't like the way the
   toolchain is handled, so I want to do it differently. Currently, your
   only way is to fork the whole distro or do dangerous stuff with
   overlays.
   
   Imagine gentoo would actually be a small repository of core packages
   with lots of optional user contributed extenions of all kinds. You'd
   only need to fork the core and add those extensions you like.
   
   Similarly... you don't like the way ruby is handled? Well, apart from
   dev-lang/ruby maybe, there'd be no ruby gems in the tree anyway. So
   there can be different approaches of packaging ruby gems and you choose
   which to use or if you want to do it completely different. And there
   would be no complicated configuration required to prevent in-tree ruby
   packages getting pulled in, because there are none.

 Isn't this all stuff about handling some kind of pointers? Don't like
 the toolchain? Point to another one. Don't like the way ruby is handled?
 Point to another one.

 So, is it about overlays? No. I'd say overlays are some kind of poor
 pointers for many reasons.

 Hence, why not adding the pointers we are all missing and rethinking the
 other pointers?


am I the only one who thinks that this way leads to madness?

Version conflicts are bad enough. No multiply that with a bunch of
overlays, all having their own libXY with just some tiny, tiny
differences, and another bunch of overlays who want libXY from certain
others

if that does not give you nightmares, I don't know what.

 Version conflicts are bad enough.
 First, version conflicts have their roots in the support for versions of
 libraries in softwares. This is the best place to fix that when
 possible.

 When it comes to ebuilds maintainers, version conflicts are about all
 about DECLARATIONS. If software A need Y-v1..12, we should have a way
 for the maintainers to declare that A relies on Y-v1..12 and let the
 dependency softwares to the hard job and admin/users handle them the way
 they want.
 Today, this is badly managed with implicit expectations everywhere.

 Also, there are ways to overcome version conflicts. Slots are one of
 them.

   No multiply that with a bunch of
 overlays, all having their own libXY with just some tiny, tiny

 That's a reason why I said that overlays are a poor kind of pointers.

 For overlay maintainers today, if the main portage tree does not offer
 what they expect, the only option they have is to rewrite their own
 static dependency tree with their own ebuilds. That sucks.

 Portage should support a way to expose ALL the conditions for a software
 to work and update installed libraries to match the requirements.

 I don't think having exposed requirements would explode the time needed
 to calculate the dependency tree because this does not add paths to the
 tree. It only validates or invalidates paths.

 And if time for dependency resolution would become a real problem, there
 are ways to solve that. One could be making pre-calcultated caches of
 parts of tree/paths.


which works so well with different useflags.

portage is already almost unbearable slow. The 'distributed model' would
add so much complexity, we can forget USE.

 This sounds nice in principle, but making it work is not trivial.

 Suppose my package works with gcc-1.2.3.4 with a list of 14 specific
 patches and no others, and glibc-1.2.3.4 with another list of 14
 patches and no others.  Now suppose 300 other packages have similar
 requirements.
 To make it simple, this is almost irrelevant IMHO.
