( not all on samba topic but one i wanted to share. ) 


I did read :  https://wiki.samba.org/index.php/LinuxCIFSKernel 

mainly because of, from that page, 

4.7 Kernel 

Fix badlock regression for guest mounts (mount with -o guest can fail to Samba servers when patched for badlock). 

I encountered such a problem yesterday. Luckly not in the office.. 


The fix. 

Cifs.ko version updated to 2.09. 

Minor fixes: including NetApp DFSpathname issue and SPNEGO fix. Persistent handle reconnect fixes 

(https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5a4f7e8e7ff5e81f57b08797cca41d307878dfc7 ) 

But thats kernel 4.7 


Now i saw my debian systems is running 3.16.0 kernel ( cifs 2.03 ), anyone tried a 4.7 kernel already? 



And  https://wiki.samba.org/index.php/SMB3_kernel_status for the SMB3.1.1  

The minimum version for use of the Linux kernel SMB3 support is kernel version 3.12 (or backport of cifs.ko module version 2.02 or later)

 but kernel version 3.18 or later (or equivalent, ie cifs module version 2.04 or later) is recommended for best SMB3 support.


And I saw in the win10 the SMB Direct so i was bit reading into this. 

Im looking in to the SMB 3.0 over RDMA, i can asume this is not implementes yet? 

Not that im in a rush here.



( and off topic ) 

Just got a email about flip feng shui attacks from my hoster. If you use VM’s you better read this. 

Read here :  https://www.vusec.net/projects/flip-feng-shui/  

Flip Feng Shui (FFS) is a new exploitation vector that allows an attacker virtual machine (VM) to flip a bit in a memory page of a victim VM that runs on the same host as the attacker VM
