From be17dc9d31e805c03372b690dde67838b3bfc12d Mon Sep 17 00:00:00 2001

Subject: [PATCH] libssh: when keyboard-interactive auth fails, try password
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The state machine had a mistake in that it would not carry on to that
next step.
This also adds a verbose output what methods that are available from the
server and renames the macros that change to the next auth methods to
try.
Reported-by: 左潇峰
Fixes #11196
Closes #11197

Subject: [PATCH] lib: unify the upload/method handling
By making sure we set state.upload based on the set.method value and not
independently as set.upload, we reduce confusion and mixup risks, both
internally and externally.

From 61275672b46d9abb3285740467b882e22ed75da8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] cookie: remove unnecessary struct fields
Plus: reduce the hash table size from 256 to 63. It seems unlikely to
make much of a speed difference for most use cases but saves 1.5KB of
data per instance.
Closes #11862
