After the updates I have a permission problem with my samba share. The share is mounted via fstab:
# Openwrt Transfer
//192.168.3.2/transfer /mnt/transfer cifs guest,uid=1000,_netdev,noauto,x-systemd.automount,user,vers=1.0 0 0
After the update the permissons of user shown in dolphin is "65534", group is "nobody".
So, I'm unable to create or copy anything on the share.
I rollback the updates and everythings fine again.
But, I don't know, if this is a problem with the kernel or an other update.
