Daniel Cohen afb6bcd081 ssh: remove slow unnecessary diffie-hellman-group-exchange primality check 
The existing implementation validates that the prime returned by the server is, in fact, prime, which is extremely slow, especially for large key sizes.

As other implementations, including OpenSSH, do not verify the primality of the provided parameters, this change removes that check.

and sometimes:

Erick Tryzelaar 279210d13f ssh: don't err out on channel request msgs to unknown channels 
rfc4254 section 5.4 states that channel request messages sent to an
unrecognized channel should be replied with a `SSH_MSG_CHANNEL_FAILURE`,
rather than erring out and closing the mux. This can occur with servers
like openssh-portable, which can begin to close a channel and also use
that channel for keepalives before it has received a closed response
from the client.

Michael Munday 4b2356b1ed poly1305: modify s390x assembly to implement MAC interface 
The vector (vx) implementation has been updated to read in the
state and update it - as opposed to being a single shot function.
This has allowed the new MAC interface can be implemented.

For performance reasons s390x uses a larger buffer than the generic
implementation. There is a relatively high fixed cost to read the
state, calculate the key coefficients and serialize the state, so
it makes sense to buffer more blocks before calling it.

For now I've had to remove the faster VMSL implementation. It is
too complex for me to update in time for Go 1.15. At some point
I'd like to revisit it but for now it looks like using the MAC
interface is more of a win than using VMSL.

The benchmarks show considerable improvements when using the MAC
interface. The Sum benchmarks show slowdown due to a combination
of the removal of the VMSL implementation and also the added
overhead from splitting the summation function into multiple parts.

Filippo Valsorda 44a6062868 poly1305: add (*MAC).Verify API and use it in chacha20poly1305 
Also, make sure New inlines so it does not cause an allocation. With
this, we have a zero allocation poly1305 flow and a zero allocation
generic chacha20poly1305 composition! \o/

While at it, remove some redundant code, and prepare to drop some
complexity once the last assembly implementation of sum is dropped.

Redundant bound checks on loading key and nonce as uint32s in newUnauthenticatedCipher
are eliminated.

In the main block loop, two changes were made:
1. Specialise the xor function to addXor, so the final block state variables don't need to be
separately incremented by the initial block state before XORing with the input block.
2. Change the loop condition to be bound by len(src) >=64 and len(dst) >= 64.
This eliminates all bound checks later in the load-xor-store stage.
As a result, src and dst are resliced in-place after each block.

Ian Lance Taylor 32487eceac openpgp/packet: ensure that first partial packet is 512 bytes 
This requirement is from RFC 4880 4.2.2.4.

Also simplify the partialLengthWriter loop. The old code worked but
was written in a confusing way, with a loop whose terminating condition
didn't make sense and was never true in practice.
Rewrite it to more clearly do a set of partial writes of decreasing size.

Fixes golang/go#32474

Filippo Valsorda bac4c82f69 ssh: return an error for malformed ed25519 public keys rather than panic 
An attacker can craft an ssh-ed25519 or sk-ssh-ed25519@openssh.com
public key, such that the library will panic when trying to verify a
signature with it. Clients can deliver such a public key and signature
to any golang.org/x/crypto/ssh server with a PublicKeyCallback, and
servers can deliver them to any golang.org/x/crypto/ssh client.

This issue was discovered and reported by Alex Gaynor, Fish in a Barrel,
and is tracked as CVE-2020-9283.

You can test that you're using the correct OID by performing a TLS-ALPN-01 challenge against a Pebble (https://github.com/letsencrypt/pebble) ACME server running with the -strict argument. This implementation will reject the obsolete OID.

Alex Brainman ecb85df213 ssh/terminal: adjust ReadConsole rules on windows 
CL 212377 changed end of input character on windows - from \n to \r.
But CL 212377 did not adjust ReadConsole accordingly. For example,
after CL 212377 \n was still used to end of password processing,
and \r was ignored.

This CL swaps these rules - \r is now used to end password processing,
and \n are ignored. The change only affects windows, all non windows
code should work as before.

This CL also adjusts TestReadPasswordLineEnd to fit new rules.
