v2:
- update comments of smb2_get_data_area_len().
- fix wrong buffer size check in fsctl_query_iface_info_ioctl().
- fix 32bit overflow in smb2_set_info.
v3:
- add buffer check for ByteCount of smb negotiate request.
- Moved buffer check of to the top of loop to avoid unneeded behavior when
out_buf_len is smaller than network_interface_info_ioctl_rsp.
- get correct out_buf_len which doesn't exceed max stream protocol length.
- subtract single smb2_lock_element for correct buffer size check in
ksmbd_smb2_check_message().
Namjae Jeon (5):
ksmbd: add the check to vaildate if stream protocol length exceeds
maximum value
ksmbd: add validation in smb2_ioctl
ksmbd: add request buffer validation in smb2_set_info
ksmbd: check strictly data area in ksmbd_smb2_check_message()
ksmbd: add validation in smb2 negotiate
