Reference: https://git.kernel.org/torvalds/linux/c/4bc59477c329

-------------------------------

ksmbd limit read/write/trans buffer size not to exceed maximum 8MB.
And set the minimum value of max response buffer size to 64KB.
Windows client doesn't send session setup request if ksmbd set max
trans/read/write size lower than 64KB in smb2 negotiate.
It means windows allow at least 64 KB or more about this value.

Permission checking and copying over ownership information is the task
of the underlying filesystem not ksmbd. The order is also wrong here.
This modifies the inode before notify_change(). If notify_change() fails
this will have changed ownership nonetheless. All of this is unnecessary
though since the underlying filesystem's ->setattr handler will do all
this (if required) by itself.

-------------------------------

ksmbd create socket with IPv6 to listen both IPv4 and IPv6 connection
from client. Server should send IP addresses of NICs through network
interface info response. If Client connection is IPv4, Server should
fill IPv4 address in response buffer. But ss_family is always PF_INET6
on IPv6 socket. So This patch add ipv6_addr_v4mapped check to know
client connection is IPv4.

Both Windows 10's SMB server and samba return STATUS_OBJECT_PATH_NOT_FOUND
when trying to access a nonexistent path.

This fixes Windows 10 File History tool. The latter relies on the server
returning STATUS_OBJECT_PATH_NOT_FOUND to figure out what part of the
target path needs to be created. Returning STATUS_OBJECT_NAME_INVALID
will make it stop and display an error to the user.

-------------------------------

Support for faster packet signing (using GMAC instead of CMAC) can
now be negotiated to some newer servers, including Windows.
See MS-SMB2 section 2.2.3.17.

This patch adds support for sending the new negotiate context with two
supported signing algorithms(AES-CMAC, HMAC-SHA256).
If client add support for AES_GMAC, Server will be supported later
depend on it.
