Ah, well, I dont care about various vendors. I only care about Linux,
BSD and SunOS kernel behaviour ;)

That said, TCP-MD5 signature renders this mostly moot, and deployment
of TCP-MD5 has increased a lot since the last round of "BGP TCP is
insecure!" non-issues came up. Many IXes and peers now require
TCP-MD5.

The rights and wrongs of TCP-MD5 notwithstanding, it'd be nice if
Linux could support this. Anyone running BGP on Linux at moment must
patch their kernel - or else just switch to Free/Open BSD.
