GSSAPI key exchange support
This patch has been rejected upstream: "None of the OpenSSH developers are
in favour of adding this, and this situation has not changed for several
years. This is not a slight on Simon's patch, which is of fine quality, but
just that a) we don't trust GSSAPI implementations that much and b) we don't
like adding new KEX since they are pre-auth attack surface. This one is
particularly scary, since it requires hooks out to typically root-owned
system resources."
However, quite a lot of people rely on this in Debian, and it's better to
have it merged into the main openssh package rather than having separate
-krb5 packages (as we used to have). It seems to have a generally good
security history.

1 | Portable OpenSSH with GSSAPI Key Exchange patches | ||
2 | ================================================= | ||
3 | |||
4 | Currently, there are two branches with gssapi key exchange related | ||
5 | patches: | ||
6 | |||
7 | * fedora/master: Changes that are shipped in Fedora | ||
8 | * debian/master: Changes that are shipped in Debian | ||
9 | |||
10 | The target is to converge to a shared repository with single master | ||
11 | branch from where we could build releases for both OSes. | ||
12 | |||
13 | |||
14 | What is in: | ||
15 | |||
16 | * The original patch implementing missing parts of RFC4462 by Simon Wilkinson | ||
17 | adapted to the current OpenSSH versions and with several fixes | ||
18 | * New methods for GSSAPI Kex from IETF draft [1] from Jakub Jelen | ||
19 | |||
20 | |||
21 | Missing kerberos-related parts: | ||
22 | |||
23 | * .k5login and .kusers support available in Fedora [2] [3]. | ||
24 | * Improved handling of kerberos ccache location [4] | ||
