undefined smb_messages in samba-4.3.13

[sandeep nag]

Below is the smbd generated after building samba-4.3.13
[sandeep at machine-10 samba-4.3.13]$ nm ./bin/default/source3/smbd/smbd |
grep smb_messages
[sandeep at machine-10 samba-4.3.13]$


I see in the following in samba-4.3.13 code's  smb_server folder:
[sandeep at r320-sys-10 source4]$ ls smb_server/
blob.c  handle.c  management.c  service_smb.c  session.c  smb  smb2
smb_server.c  smb_server.h  tcon.c  wscript_build
[sandeep at r320-sys-10 source4]$ ls smb_server/smb2
fileinfo.c  fileio.c  find.c  keepalive.c  negprot.c  receive.c
sesssetup.c  smb2_server.h  tcon.c  wscript_build


Which says that receive.c is built only for SMB,SMB2 protocol whereas in
SMB3 it is not.


I am looking for help in:
How can we intercept operations in SMB3?
Should i include receive.c in SMB3 build or is their any alternative?


Thanks in advance,
