spnego_negtokeninit.asn1.h and spnego_negtokentarg.asn1.h
have to be generated before asn1.o is compiled.
Because of parallel build, the dependency could be broken,
we need to specify the dependency in Makefile.

When running generic/591 after smb2 leases is enable, all smb2 lease ack
requests failed in ksmbd. because cifs client seems to support only smb2
v2 lease. So cifs doesn't update lease state in ack request if epoch is
not set in smb2 lease break request from ksmbd. epoch is used for smb2
v2 leases. So this patch add smb2 create v2 lease context and set
increased epoch in smb2 lease break response.

If *pos or *pos + count is greater than v_len, It will read beyond

size of the buffer.

If ksmbd_vfs_getcasexattr() returns -ENOMEM, stream_buf is NULL,
it will cause null-ptr-deref when using it to copy memory. So we
need check the return value of ksmbd_vfs_getcasexattr() by comparing
with 0.

Returning TreeID=0 is valid behaviour according to [MS-SMB2] 2.2.1.2:
TreeId (4 bytes): Uniquely identifies the tree connect for the command.
This MUST be 0 for the SMB2 TREE_CONNECT Request. The TreeId can be
any unsigned 32-bit integer that is received from a previous
SMB2 TREE_CONNECT Response. TreeId SHOULD be set to 0 for the
following commands:
[...]
However, some client implementations reject it as invalid. Windows10
assigns ids starting from 1, and samba4 returns a random uint32_t
which suggests there may be other clients that consider it is
invalid behaviour.
