And what bug is this? (Sorry if you already stated it, I didn't see it while
going through the archives of this conversation).  I use taskfile and have a
vested interest in getting all taskfile bugs fixed.  FYI there was a bug
where pio-out taskfile commands could oops because of a null request
pointer; the patch I submitted for that one should be in the 2.6.14 rc
series now.

I've attached a crash ooops log from 2.6.12.

Email me (mlord@pobox.com) if you'd like to get in touch
with the chap who has been painstakingly working this
from the userspace side of the TASKFILE ioctls.

Cheers

at runlevel 1 i get marks crashes too, first the null pointer (which is
evertime at same address and hopefully fixed with tims patch) then after
journal commit intervall (mounted xfs,ext3) panic in irq handler and on
unmounted drives lost interrupt without system stall.

(yes i want to be able to seclock down mounted fs drives)

strange: with the system full running at level 2 i got only what i
reported yesterday on 4 tries.

ive setup a debug 2.6.13.4 and check now, but i can patch up to latest
2.6.14 rc.

no logs from the irq-handler panic so far.

hdparm ATA Security Options return errors

[thomas schorpp]

hi,

hdparm

ATA Security Options:
 --security-unlock PWD          Unlock drive, using password PWD (DANGEROUS)
 --security-set-pass PWD        Lock drive, using password PWD (DANGEROUS)
 --security-disable PWD         Disable drive locking, using password
PWD (DANGEROUS)
 --security-mode MODE           Specify user/master password and
high/maximum security

fail by returning errors "cannot allocate mem", "invalid argument", with

hdparm binary from debian stable...sid / whax /knoppix with kernels

.

does it help to compile hdparm from source against the vanilla kernel?

wheres the latest source? biblio? or is there a cvs?

meanwhile ill take a look at the debian sid source package's code...

hdparm.c line 101

static char security_password[64];

shouldnt it be 128? passphrase + padding to 128 bytes?

Re: hdparm ATA Security Options return errors

[Mark Lord]

I think the entire set of ATA security patches that were
sent to me for hdparm are bogus -- I lack the setup here
to try them, but another kind person is preparing patches
for hdparm to fix them.

Along the way, he has also discovered bugs in the ATA_TASKFILE
ioctls, but we have yet to work out a good description/patch
for the broken bits there.

Cheers

yes, ive just tried to debug this for the last hours, but ive more
trivial problems here, cant run suid root executables anymore, same with
cdrecord *shame*

dont expect too much, ive to read about this taskfile stuff first.
but i can test with an older 20gb ata-6 seagate...

if no one mentioned before:

these security features should be TODO for linux-usb, scsi-emu ata, too,
to lock external usb harddrives or SATA for (relative secure) transport.

theres some work for enabling S.M.A.R.T for external usb drives and SATA
going on.

suggest integrating the efforts, if not done yet.

hdparm-6.3 is now out, with working security commands.

But there is still a bug deep in the IDE taskfile code
that sometimes causes problems.  Someday I might have time
to dig deeper into the kernel and fix that issue.

test01:

vanilla kernel 2.6.13.4

no security enabled before, no passwort.

hdparm --security-disable xxxx /dev/hde
