Bug ID: 222684
Summary: AH hmac-sha2-384 is incompatible with Linux AH
hmac(sha384)
Product: Base System
Version: 11.1-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: freebsd-bugs at FreeBSD.org
Reporter: jasonmader at gmail.com
I thought the problem might be because Linux is putting too many bits on the
wire, but it might be a IPv6 padding issue covered here,
https://bugzilla.suse.com/show_bug.cgi?id=1019412
FreeBSD side:
add -n ::SRC ::DST ah 0xSPI -m transport -A hmac-sha2-384 0xKEY;
Linux side:
ip xfrm state add src ::SRC dst ::DST proto ah spi 0xSPI auth "hmac(sha384)"
0xKEY mode transport
If the SUSE people are correct about the behavior, FreeBSD IPv6 Authenticated
Header might not be properly padded.
