Recent review has revealed several bugs in obscure protocol
implementations that can be exploited by local users for denial of
service or privilege escalation.
The x25 protocol (PF_X25) receives only 'odd fixes'. There appear to
be no published applications for it, and it has never progressed
beyond 'experimental' status.
This protocol generally should not be enabled by distributions, since
the cost of a security flaw affecting all installed systems presumably
outweighs the benefit to the few (if any) legitimate users.

I'm somewhat less sure about this one; maybe it's improving? But there
is little enough sign of any usefulness after 10 years.
There are several X25 dependencies that presumably should be moved too.
Ben.

No. If you don't like it then don't enable it.

There are users of linux X.25 for production environments, please don't..
It works well enough, there have been some X.25 over TCP bits of code
floating around the Internet and mailing lists.
There is an x25 loopback device on sourceforge using tuntap which I
have been using to test slowly removing the bkls.
Regards,
Andrew.
