Problems with crypto-patches in kernel 2.4.21??

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,
I am using kernel 2.4.21 with the corresponding
crypto-patches (patch-int-2.4.21.0.bz2) and loop-patch
(loop-jari-2.4.21.0.patch). When writing a large
amount of data to an encrypted folder residing in a
single file, the complete system crashes.

I am doing the following:

# dd if=/dev/urandom of=~/.crypto bs=1024 count=2048
# losetup -e aes -k 256 /dev/loop0 ~/.crypto
# mke2fs /dev/loop0
# mount /dev/loop0 ~/crypto
# cp -a ~/unencrypted_folder ~/crypto

After a few minutes of copying data there is no more
harddisk activity but the last cp command does not
complete. Any services on the machine (sshd, httpd,
ftpd) are no longer reachable. It is possible to type
the user name after the login prompt at the local
console, but pressing enter then does not give the
prompt for the password. The kernel is still routing
ip packets though.

I eventually have to press the reset button.

Any clues?
