2018-02-26upstream: Add experimental support for PQC XMSS keys (Extendedmarkus@openbsd.org
Hash-Based Signatures) The code is not compiled in by default (see WITH_XMSS in Makefile.inc) Joint work with stefan-lukas_gazdag at genua.eu See https://tools.ietf.org/html/draft-irtf-cfrg-xmss-hash-based-signatures-12 ok djm@ OpenBSD-Commit-ID: ef3eccb96762a5d6f135d7daeef608df7776a7ac

Drop compatibility hacks for some ancient SSH implementations, including ssh.com <=2.* and OpenSSH <= 3.*. These versions were all released in or before 2001 and predate the final SSH RFCs. The hacks in question aren't necessary for RFC- compliant SSH implementations. ok markus@ OpenBSD-Commit-ID: 4be81c67db57647f907f4e881fb9341448606138

downgrade a couple more request parsing errors from process-fatal to just returning failure, making them consistent with the others that were already like that. OpenBSD-Commit-ID: c111461f7a626690a2d53018ef26557b34652918

fix regression in 7.6: failure to parse a signature request message shouldn't be fatal to the process, just the request. Reported by Ron Frederick OpenBSD-Commit-ID: e5d01b3819caa1a2ad51fc57d6ded43f48bbcc05

Replace <sys/param.h> with <limits.h> and other less dirty headers where possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution.
