Start the process of splitting sshd into separate binaries. This step splits sshd into a listener and a session binary. More splits are planned. After this changes, the listener binary will validate the configuration, load the hostkeys, listen on port 22 and manage MaxStartups only. All session handling will be performed by a new sshd-session binary that the listener fork+execs. This reduces the listener process to the minimum necessary and sets us up for future work on the sshd-session binary. feedback/ok markus@ deraadt@ NB. if you're updating via source, please restart sshd after installing, otherwise you run the risk of locking yourself out.

add "ext-info-in-auth@openssh.com" extension This adds another transport protocol extension to allow a sshd to send SSH2_MSG_EXT_INFO during user authentication, after the server has learned the username that is being logged in to. This lets sshd to update the acceptable signature algoritms for public key authentication, and allows these to be varied via sshd_config(5) "Match" directives, which are evaluated after the server learns the username being authenticated.

Update/replace the experimental post-quantim hybrid key exchange method based on Streamlined NTRU Prime (coupled with X25519). The previous sntrup4591761x25519-sha512@tinyssh.org method is replaced with sntrup761x25519-sha512@openssh.com. Per the authors, sntrup4591761 was replaced almost two years ago by sntrup761. The sntrup761 implementaion, like sntrup4591761 before it, is public domain code extracted from the SUPERCOP cryptography benchmark suite (https://bench.cr.yp.to/supercop.html). Thanks for Daniel J Bernstein for guidance on algorithm selection. Patch from Tobias Heider; feedback & ok markus@ and myself (note this both the updated method and the one that it replaced are disabled by default)

Improve strictness and control over RSA-SHA2 signature types: In ssh, when an agent fails to return a RSA-SHA2 signature when requested and falls back to RSA-SHA1 instead, retry the signature to ensure that the public key algorithm sent in the SSH_MSG_USERAUTH matches the one in the signature itself. In sshd, strictly enforce that the public key algorithm sent in the SSH_MSG_USERAUTH message matches what appears in the signature. Make the sshd_config PubkeyAcceptedKeyTypes and HostbasedAcceptedKeyTypes options control accepted signature algorithms (previously they selected supported key types). This allows these options to ban RSA-SHA1 in favour of RSA-SHA2. Add new signature algorithms "rsa-sha2-256-cert-v01@openssh.com" and "rsa-sha2-512-cert-v01@openssh.com" to force use of RSA-SHA2 signatures with certificate keys. feedback and ok markus@

ECDH/ECDSA compliance fix: these methods vary the hash function they use (SHA256/384/512) depending on the length of the curve in use. The previous code incorrectly used SHA256 in all cases. This fix will cause authentication failure when using 384 or 521-bit curve keys if one peer hasn't been upgraded and the other has. (256-bit curve keys work ok). In particular you may need to specify HostkeyAlgorithms when connecting to a server that has not been upgraded from an upgraded client. ok naddy@

Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer better performance than plain DH and DSA at the same equivalent symmetric key length, as well as much shorter keys. Only the mandatory sections of RFC5656 are implemented, specifically the three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and ECDSA. Point compression (optional in RFC5656 is NOT implemented). Certificate host and user keys using the new ECDSA key types are supported.

generate a 2*need size (~300 instead of 1024/2048) random private
exponent during the DH key agreement. according to Niels (the great
german advisor) this is safe since /etc/primes contains strong
primes only.

add support for RSA to SSH2. please test. there are now 3 types of keys: RSA1 is used by ssh-1 only, RSA and DSA are used by SSH2. you can use 'ssh-keygen -t rsa -f ssh2_rsa_file' to generate RSA keys for SSH2 and use the RSA keys for hostkeys or for user keys. SSH2 RSA or DSA keys are added to .ssh/authorised_keys2 as before. IdentityFile2, HostDsaKey and DSAAuthentication are obsolete. you can use multiple IdentityFile and HostKey for all types of keys. the option DSAAuthentication is replaced by PubkeyAuthetication.
