RFT: hdapsd for Intel MacBooks and Hewlett-Packard laptops

evgeni — Sun, 07 Mar 2010 19:29:36 GMT

After quite some time (last release 01-04-2009), hdapsd got a bit of love. Brice Arnould has contributed some code for Hewlett-Packard laptops (those supported by the hp_accel module, see drivers/hwmon/hp_accel.c) and I finally crossed all lines and wrote support for Apple MacBooks (the Intel ones, via applesmc module, see drivers/hwmon/applesmc.c). The HP code is interesting, as it support a hardware-logic mode, where hdapsd only parks the heads when told so by the HP hardware. As I do not own any compatible hardware, this is only tested by Brice himself. The Apple SMC code isn't tested at all, as I don't have the hardware either. That's why I want YOU to test it further (both, on HP and Apple) and report me bugs (mail to evgeni@debian.org preferred) if you find any :) You can get the latest source either via git from github:

git clone -b new-interfaces git://github.com/evgeni/hdapsd.git

Or from githubs tarball generator: http://github.com/evgeni/hdapsd/tarball/eb711f30395ac9bc682b14c22d8445b7ddf0b4a0 After you got the source, a simple

./autogen.sh

make

should produce a src/hdapsd binary, that you can test. I can provide Debian and Ubuntu .debs if needed too.

thinkfan_0.5.0.1-1_amd64.changes ACCEPTED

evgeni — Mon, 14 Sep 2009 16:00:57 GMT

Yay, thinkfan just got accepted by the ftp-masters.

Now all owners of noisy fans (like on my Thinkpad X300) can control these and make them a lot nicer for daily usage.
(the package has sane defaults in thinkfan.conf, but I still decided to deactivate it in /etc/default/thinkfan because you can demage your hardware quite easily when you don't know what you're doing)

How do you call your ThinkPad?

evgeni — Wed, 07 May 2008 01:41:15 GMT

ThinkPad sounds so solid and brave, not like what I am doing with it :)
So I am interested how one could call it (still having some connection to "ThinkPad").

On the net you can find:
denkmatte (hi #debian.de - anyone reading?)
denkblock (not like this cartoon)
stinkpad (even urbandictionary knows it)

Mine are called:
shinkupaddo - that what comes out if you try to "translate" ThinkPad to Japanese
chiisai - and this when you are as creative as I am and translate "small" to Japanese

And how is yours called?

Destroying data the professional way

evgeni — Thu, 19 Jul 2007 20:23:24 GMT

Yesterday I decided to reinstall my Windows XP on my Thinkpad Z61m. As I have the nice 7CD recovery set from IBM, I thought I'll just use it. ThinkWiki said, it would only remove the first partition on my drive and push its data there.
Well, it didn't.
I did not have any own recovery discs, so I just could do a "full factory reset", which wiped my whole disk :(
It didn't really wipe it, but deleted the partition table, created one big FAT partition, and one small (5GB) for the "Rescue and Recovery" tool. Only the first 8GB of the big one were filled with new data, the rest was not touched. The 5GB one was almost full.

Now I was fucked. I had backups of my home, but they were not completely up to date, and I did not have any backups of /...
So lets try some recovery.

I know my disk looked like this before RnR destroyed the partition table:
sda1: 10GB WinXP NTFS
sda2: 10GB Linux ext3 (/)
sda3: 1GB Linux swap (encrypted with LUKS)
sda4: 75GB Linux ext3 (/home, encrypted with LUKS)

Now I boot grml and use gpart (it guesses the partitions of disk), to get the real start- and end-sectors of the partitions, as they have to match exactly:
# gpart -f -l gpart.log -v /dev/sda
This needs about an hour for my 100GB disk, so get some coffee ;)

When it was done, I opened gpart.log and got some entries like this one:
type: 005(0x05)(Extended DOS)
size: 10144mb #s(20775888) s(8192016-28967903)
chs: (1023/15/63)-(1023/15/63)d (8127/0/1)-(28737/15/63)r

The "size" line looks interesing, it shows the size of the guessed partition and the start and end sectors, exactly what I wanted.
Two of the entries were ext3 (10GB) and swap (1GB), that are my / and swap, but no /home (and not the old NTFS, it was overwritten).

So I started fdisk and deleted the two IBM partitions, then I switched to sectors-view (press "u"<ENTER>).
Then I created 4 primary partitions from the data I got from gpart:
sda1: 63-<first of ext3-1>
sda2: <first of ext3>-<last of ext3>
sda3: <first of swap>-<last of swap>
sda4: <last of swap+1>-<end>

The partition table was back, now I tried to reach my data.
sda2 was perfectly mountable and contained all my / - nice!
sda3 could be opened with cryptsetup luksOpen and contained swap - nice!
sda4 - which SHOULD contain my /home - could NOT be opened with luks :(

I posted on the luks/dm-crypt mailing-list about my problem, and got the answer, I should search for the "LUKS 0xBA 0xBE" (= LUKS BABE, funny developers) header of the luks partition (I assumend the start of sda4 was wrong).
This was did by: hexdump -C /dev/sdaX |grep "4c 55 4b 53 ba be"
where X was 3 and 4, as I did not know, where exactly sda4 should start (maybe IN the swap? :()
sda3 contained only one header at offset 0, so the real header of the luks-swap.
sda4 contained one too, but not at offset 0 (where cryptsetup searched it), but at 0x00000600 (1536 decimal).

So I just needed to push the start of sda4 a bit, open fdisk, remember sector where sda4 begins, remove sda4.
Now I need to know how many sectors I should add. fdisk tells me, 1 sector=512 bytes, my offset was 1536 bytes, so exactly 3 sectors. I create a new sda4, but now it starts 3 sectors later, write the partition table, and reboot (fdisk told me to, don't ask me why).

After the reboot, head -c4 /dev/sda4 says "LUKS", yay. cryptsetup isLuks reports partition being LUKS too, and luksOpen opens it. So I have my partition back, but what is about the data (the last 5GB were overwritten).
mount mounts it without problems, but I wanted to ask fsck.
fsck /dev/mapper/home gave many inode errors, so I ran
fsck -y /dev/mapper/home after some time it was ready and had my data.

Now I can be really happy getting my stuff back, thanks open source, damn lenovo.

Created a feed for a website I needed

evgeni — Mon, 02 Apr 2007 18:52:28 GMT

After reading Nico's post about creating RSS feed for a website you want I first didn't think I could use the service, but now I recognized that I need it.

I own a ThinkPad Z61m from IBM/Lenovo and hate to track the new BIOS versions from the website.
Now I have created a RSS feed for this website, which you can find here: http://feed43.com/thinkpad-z61-bios.xml, and added it to my Firefox^WIceweasel LiveBookmarks. So I do not have to visit the IBM website for a new BIOS.

Thanks Nico!

Your battery is being recalled.

Pimp My Laptop

evgeni — Tue, 13 Feb 2007 14:39:24 GMT

oder vielleicht doch
Pimp My ThinkPad? Wie auch immer:

So sieht jetzt mein Laptop links in der Ecke aus. Wo das Designed for Debian ist, war früher ein Designed for Windows XP, aber das ist leider freiwillig abgegangen ;-)

Same procedure as every XSS, James.

Und hier sind zehn weitere nette Cross Site Scriptings, unter anderem ein paar namhafte Hardware Hersteller und Software-Giganten...
Aber zunächst eine kleine Statusmeldung wegen den alten Meldungen:
Auf Mail Nummer 1 kamen keine neuen Antworten, auf Mail Nummer 2 erhielt ich ein BOUNCE von RTL, deren Server sei nicht für Mails an Clipfish.de zuständig (laut DNS ist er das), ein Auto-Reply von hamburg.de und tatsächlich hat es Andi von netsplit.de als einziger Mensch geschafft meine Mail zu lesen, zu verstehen und zu Herzen zu nehmen. Der Fehler ist behoben, un dich erhielt einen netten Gruß und Dank per Mail. An dieser Stelle deswegen auch Dank an Andi für das Supporten von uns kleinen IRC-Netzwerken, aber ich glaube er hat in meiner formellen Mail gar nicht erkannt, dass er mich eigentlich kennt ;-)

Jaja, ihr wollt Links, HIER:

jvc-europe.com
real.de
sony-bmg.de
debian.org
ibm.com
linsprire.com
sueddeutsche.de
medion.de
teufel.de

Gleich mal wieder eine nette Mail rausschicken und auf die BOUNCEs freuen.
Schönen Sonntag-Abend noch.

PS: Vielen Dank an den netten Kölner, der XSS in meinem Gästebuch ausprobiert hat. htmlspecialchars() ist sowas von seKure ;-)

Unfaehiger Support bei unfaehigen Herstellern

evgeni — Fri, 29 Dec 2006 12:42:42 GMT

Wie ich bereits berichtet habe, besitzte ich einen beschnittenen Z61m von IBM/Lenovo. Dazu habe ich auch am 15.12. eine Mail an den Support geschickt, wie dass denn jetzt mit VT Unterstuetzung im BIOS aussieht.
Am 27.12. kam dann eine nette Mail, die ich mal auszugsweise zittiere:

"IBM/Lenovo provides free software support for the first 30 days after the
purchase of the machine.

Unfortunately, we have been unable to verify your support entitlement. This
could be because [...] it is more then 30 days
since the computer was manufactured.

Since we can not determine which country you are in" please fuckoff and search a local support (Anm: letzter Teil ist sinngemaess ergaenzt)

Aha? Was interssiert mich Software-Support? Ich will das meine Hardware nach Spezifikation funktioniert, nicht mehr.
Naja dachte ich mir, antworte ich halt mal nett wenn ich vom 23C3 in berlin wieder zuhause bin. Heute kam aber eine Erinnerung, ich soll doch bitte Antworten. Nach 2 Tagen eine Erinnerung? Boah ;-)

Nagut, hab ich gemacht, inkl CC an IBM-Germany, da die ja es nicht schaffen zu peilen dass ich aus Deutschland komme. Hab auch nett erwaehnt, dass ich Hardware- und keinen Software-Support suche und meine letzte Mail nochmal angehaengt. Mal schauen was das so wird.

Unfaehiger Hersteller des Tages - Lenovo

evgeni — Fri, 15 Dec 2006 00:18:33 GMT

Ich hab ja einen Thinkpad mit einem Core Duo T2500 drin, der von Haus aus wunderbar Intel VT (Virtualisierung) unterstützt. Aber da dachte sich Lenovo, die sind schlauer, und haben das deaktiviert, und ich kanns nicht aktivieren. Also mal ne Mail (folgt) geschickt, und ma sehen was das wird.

--

Hi,

I have a Z61m featuring an Intel Core Duo T2500, which _should_ support Intel VT ([1], [2]). However, when I try to start an application, which would use this virtualization extension, it says VT is disabled in the BIOS, but there is no BIOS-option for enabling VT (only SMP, which is enabled). So my question is: are there plans for adding such a BIOS-option to the next versions or will I have to drive a Ferrari without gear-shift until I get a Lamborghini?

Kind Regards
Evgeni Golov
