10Subject: [PATCH] upstream: implement "strict key exchange" in ssh and sshd
11
12This adds a protocol extension to improve the integrity of the SSH
13transport protocol, particular in and around the initial key exchange
14(KEX) phase.
15
16Full details of the extension are in the PROTOCOL file.

43+1.9 transport: strict key exchange extension
44+
45+OpenSSH supports a number of transport-layer hardening measures under
46+a "strict KEX" feature. This feature is signalled similarly to the
47+RFC8308 ext-info feature: by including a additional algorithm in the
48+initiial SSH2_MSG_KEXINIT kex_algorithms field. The client may append
49+"kex-strict-c-v00@openssh.com" to its kex_algorithms and the server
50+may append "kex-strict-s-v00@openssh.com". These pseudo-algorithms
51+are only valid in the initial SSH2_MSG_KEXINIT and MUST be ignored
52+if they are present in subsequent SSH2_MSG_KEXINIT packets.
53+
54+When an endpoint that supports this extension observes this algorithm
55+name in a peer's KEXINIT packet, it MUST make the following changes to
56+the the protocol:
57+
58+a) During initial KEX, terminate the connection if any unexpected or
59+ out-of-sequence packet is received. This includes terminating the
60+ connection if the first packet received is not SSH2_MSG_KEXINIT.
61+ Unexpected packets for the purpose of strict KEX include messages
62+ that are otherwise valid at any time during the connection such as
63+ SSH2_MSG_DEBUG and SSH2_MSG_IGNORE.
64+b) After sending or receiving a SSH2_MSG_NEWKEYS message, reset the
65+ packet sequence number to zero. This behaviour persists for the
66+ duration of the connection (i.e. not just the first
67+ SSH2_MSG_NEWKEYS).

4Subject: [PATCH] upstream: fix AuthorizedPrincipalsCommand when
5 AuthorizedKeysCommand

9 therefore I dropped that chunk of the code.
