geli init -a hmac/sha256 does not work properly

2008-09-05 Thread Cem Kayali


Hello all there!...

Once i would like to enable disk encryption with geli approcah, i 
noticed following problem:




CASE 1 | SUCCES
---
geli init -b -e aes -l 256 -s 4096 /dev/ad4s1
  
This initializes geli without problem, and then once you run 'bsdlabel 
-w /dev/ad4s1' it goes as expected.
  
 
CASE 2 | FAIL

---
geli init -b -e aes -l 256 -s 8192 /dev/ad4s1

This initializes geli with a warning message 'sector size is bigger than 
the page size' and also 'bsdlabel -w /dev/ad4s1' fails with following 
notice: 'bsdlabel: /dev/ad4s1 read: invalid argument'
 

CASE 3 | FAIL

---
geli init -b -e aes -l 256 -s 4096 -a hmac/sha256 /dev/ad4s1

This initializes geli with a warning message 'sector size is bigger than 
the page size' and also 'bsdlabel -w /dev/ad4s1' fails with following 
notice: 'bsdlabel: /dev/ad4s1 read: invalid argument'
  

   

In short, if i enable 'data integrity verification' or if i increase 
'sector size', 'bsdlabel -w' gives error message.




I thank you in advance for advises.


Regards,
Cem

Sorry, forgot to mention: This is FreeBSD 7.0 on i386 machine with SATA 
mode enabled on bios.
