The kernel 5.15 is out and has many new features and improvements.
The new kernel has already implemented on the my tinylinux: changelog.
I have tested the new ntfs driver ( NTFS3 ) and the SMB3 server support ( ksmbd ), the ksmbd userspace tools have been added to the tinylinux.
ksmbd quick test. ( KSMBD screencast )
Start a VM with vmstart, here a screencast that shows how to start a VM screencast
- Enter the VM:
sshe 10.0.3.1 - Load the ksmb module:
modprobe ksmbd - Create the configuration directory:
mkdir /etc/ksmbd - Add a share “on the fly”:
ksmbd.addshare -a myshare -o "guest ok = yes, writable = yes, path = /usr/share/doc" - Start ksmbd user space daemon:
ksmbd.mountd
Now the share can be mounted or accessed from the host, e.g:
smbclient //10.0.3.1/myshare
Enter WORKGROUP\root's password:
Anonymous login successful
Try "help" to get a list of possible commands.
smb: >ls

- Connecting the monitor interface to check the block devices already connected:
echo "info block" | ncat -U /tmp/mon.1

- Now I add the sdb1 partition that contains window 10 ( I use only for testing and doesn’t contain any important data )
echo "drive_add 1 if=none,file=/dev/sdb1,format=raw,id=disk1" | ncat -U /tmp/mon.1
OK
echo "device_add virtio-blk-pci,drive=disk1,id=myvirtio1" | ncat -U /tmp/mon.1
