            Bug ID: 228854
           Summary: dynamically loading ipsec module broken for
                    VIMAGE/VNET enabled kernel
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: zarychtam at plan-b.pwste.edu.pl

the first introduction of dynamically loadable ipsec and tcpmd5 modules into
STABLE branch. Since VIMAGE + 11-STABLE is officially unsupported I didn't
report this issue before. Now I have a box running CURRNENT, so I could test
this and confirm that CURRENT branch is also affected.

Loading dynamically ipsec.ko module is broken for both STABLE and CURRENT.

Quick steps for reproduction. 

KERNCONF:
include GENERIC
nooptions       IPSEC

# kldload ipsec
kldload: an error occurred while loading module ipsec. Please check dmesg(8)
for more details.

# dmesg | tail -1
linker_load_file: /boot/kernel/ipsec.ko - unsupported file type

Let me also mention, that presence of VIMAGE option is and always was
irrelevant to loading tcpmd5.ko module.
