# Date: Sun, 20 Apr 2014 17:14:08 +1000 (EST)
# From: Damien Miller <djm@mindrot.org>
# To: openssh-unix-dev@mindrot.org
# Subject: bad bignum encoding for curve25519-sha256@libssh.org
# Message-ID: <alpine.BSO.2.11.1404201713390.26134@natsu.mindrot.org>
#
# Hi,
#
# So I screwed up when writing the support for the curve25519 KEX method
# that doesn't depend on OpenSSL's BIGNUM type - a bug in my code left
# leading zero bytes where they should have been skipped. The impact of
# this is that OpenSSH 6.5 and 6.6 will fail during key exchange with a
# peer that implements curve25519-sha256@libssh.org properly about 0.2%
# of the time (one in every 512ish connections).
#
# We've fixed this for OpenSSH 6.7 by avoiding the curve25519-sha256
# key exchange for previous versions, but I'd recommend distributors
# of OpenSSH apply this patch so the affected code doesn't become
# too entrenched in LTS releases.
#
# The patch fixes the bug and makes OpenSSH identify itself as 6.6.1 so as
# to distinguish itself from the incorrect versions so the compatibility
# code to disable the affected KEX isn't activated.
#
# I've committed this on the 6.6 branch too.
#
# Apologies for the hassle.
#

# HG changeset patch
# Parent 717873621cf4991164c61caafd9ac07473231f10
# Simple implementation of FIPS 140-2 selfchecks. Use OpenSSL to generate and
# verify checksums of binaries. Any hash iused in OpenSSH can be used (MD5 would
# obviously be a poor choice, since OpenSSL would barf and abort immediately in
# FIPS mode). SHA-2 seems to be a reasonable choice.
#
# The logic of the checks is as follows: decide whether FIPS mode is mandated
# (either by checking /proc/sys/crypto/fips_enabled or envoroinment variable
# SSH_FORCE_FIPS. In FIPS mode, checksums are required to match (inability to
# retrieve pre-calculated hash is a fatal error). In non-FIPS mode the checks
# still must be performed, unless the hashes are not installed. Thus if the hash
# file is not found (or the hash matches), proceed in non-FIPS mode and abort
# otherwise.

+HOW TO CONFIGURE SSH FOR OTHER LDAP CONFIGURATION / SERVER /SCHEMA
+
+You can adjust search format string in /etc/ldap.conf using
+ 1) SSH_Filter option to limit results for only specified users
+ (this appends search condition after original query)
+ 2) Search_Format option to define your own search string using expansion
+ characters %u for username, %c for objectclass and %f for above mentioned filter.
+
+Example:
+Search_Format (&(objectclass=posixAccount)(objectclass=ldapPublicKey)(uid=%u)%f)
