[Bug 3356] sshconnect2: SSH_MSG_EXT_INFO implementation seems broken based on RFC 8308
...nately, the 2nd KEX_INFO message is fairly useless anyway because it happens too late to affect userauth. E.g. it's not possible to use EXT_INFO to vary server-sig-algs per user which is the one thing we'd want to be able to do with it currently. It would be usable for the other options in RFC8308, but IMO they are either irrelevant to OpenSSH ("elevation"), already implemented differently in OpenSSH ("zlib at openssh.com") just useless "no-flow-control" (a peer could just advertise arbitrarily large channel windows). The attached patch relaxes reception of the...

Automatic FIDO2 key negotiation (request for comments)
...nformation or accessible key material so this is safe to do) 2. Add a method to send a list of understood *-sk" publickeys from authorized_keys to the client An appropriate method to implement #2 without reverting to the more invasive alternate-auth-method would seem to be via SSH extensions (RFC8308). If both the client and the server signal their support for the extension a list of known *-sk keys could be sent after a user is selected. This would then let the client select a key without needing the private key file. This should also prevent any incompatibilities between clients with and with...

[PATCH] PROTOCOL: make section numbers unique
...duration of the connection (i.e. not just the first SSH2_MSG_NEWKEYS). -1.10 transport: SSH2_MSG_EXT_INFO during user authentication +1.11 transport: SSH2_MSG_EXT_INFO during user authentication This protocol extension allows the SSH2_MSG_EXT_INFO to be sent during user authentication. RFC8308 does allow a second -- 2.42.1
