CIFS mount is failed on 5.23

[Ilya Zonov]

Hello!

 

I have faced with following issue on CubieBoard. After upgrade from 5.11 to 5.23 I can't mount cifs remote drive (Apple Time Capsule). There is only one log in syslog during mount attempt.

sun4i-ss 1c15000.crypto-engine: ERROR: Empty IV

Is it known issue?

[Igor]

Unknown issue.

 

Try upgrade kernel to the one from daily (4.8.6) or development build (4.9.x).

[gTs2]

or try putting

blacklist sun4i_ss

into 

 

/etc/modprobe.d/sun4i.conf

[Ilya Zonov]

Hello!

 

I have tested @gTS2 solution. Cifs mount works fine with sun4i_ss in blacklist. What I miss with this option?

 

@Igor, I will test daily and dev kernels later.

[Ilya Zonov]

Hi, Igor!

 

I have tested 4.9.0 kernel on my Cubieboard (A10, Debian jessie). The same issue:

Also I have tried to downgrade to 3.4 kernel. But I received unbootable image. Board just switch off after "Starting kernel". The same issue after clean install 5.20 with legacy 3.4 kernel.

 

It seems module blacklist is the only option now.

[sooperior]

I think as a new bug on the allwinner security system sun4i-ss kernel module (maybe new version in armbian) or something changed on the armbian kernel that conflicts with this module.

 

I have come to the same problem with ecryptfs, which internally uses ss.

sun4i-ss 1c15000.crypto-engine: ERROR: Empty IV

 

I have tested the same solution (blacklisting module) and it works. You just lose hardware acceleration (=slower)

sooperior, thanks for info. Where can we report this issue?

hello i have a same problem, 

 

mount.cifs //192.168.1.10/Elements /media/elements/

Password for root@//192.168.1.10/Elements:  

mount error(22): Invalid argument

Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

how can fix problem??

 

thx

[martinayotte]

You need to provide option to specify username, look at the man page. Also you can avoid calling mount.cifs directly and use traditional mount :

mount -t cifs //server/share /mnt --verbose -o user=username

[eternalWalker]

(?)

 apt-get install cifs-utils

 

great
