Hi all, in the past week I've been having problems with the latest
cryptodev-2.6 tree under UML. One was resolved; but 2 wasn't.
PROBLEM ONE: Compilation
When compiling, I get
In file included from include2/asm/rwsem.h:4,
from /var/tmp/uml/cryptodev-2.6/include/linux/rwsem.h:24,
... <snipped> ...
include/asm/arch/rwsem.h:165: error: 'struct cpuinfo_um' has no
member named 'x86'
I wasn't alone, as this post showed:
<http://www.mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg233332.html>.
Thankfully that post mentioned the patch at
<http://lkml.org/lkml/2007/11/19/220> which resolved it.
PROBLEM TWO: setkey()
After compilation I was able to run UML. But "modprobe tcrypt mode=3"
gave the following error:
... snipped...
testing cbc(des) encryption
test 1 (64 bit key):
setkey() failed flags=200000
testing cbc(des) decryption
test 1 (64 bit key):
setkey() failed flags=200000
PROBLEM THREE: Unable to remove chainiv
Once loaded, chainiv could not be removed. For example:
[root@localhost ~]# lsmod
Module Size Used by
cbc 3392 0
des_generic 16480 0
ecb 2496 0
chainiv 2232 3
crypto_blkcipher 8516 3 cbc,ecb,chainiv
cryptomgr 2688 0
crypto_algapi 11936 6
cbc,des_generic,ecb,chainiv,crypto_blkcipher,cryptomgr
binfmt_misc 7816 1
[root@localhost ~]# modprobe -r cbc des ecb
[root@localhost ~]# lsmod
Module Size Used by
chainiv 2232 4
crypto_blkcipher 8516 1 chainiv
cryptomgr 2688 0
crypto_algapi 11936 3 chainiv,crypto_blkcipher,cryptomgr
binfmt_misc 7816 1
[root@localhost ~]# modprobe -r chainiv
FATAL: Module chainiv is in use.
Notice that the chainiv "Used by" field seems to be wrong.
Anyone else facing the same problems? I've resorted to rolling back to
19f4711b.... in the meantime but obviously this is not a long-term
solution. Would be glad if someone can point me in the right
directions to resolve these problems.
