libssh2: convert over to use dynbuf

2020-05-05T12:54:07+00:00

In my very basic test that lists sftp://127.0.0.1/tmp/, this patched
code makes 161 allocations compared to 194 in git master. A 17%
reduction.

Closes #5336

libssh2: set the expected total size in SCP upload init

2020-05-02T14:38:48+00:00

... as otherwise the progress callback gets called without that
information, making the progress meter have less info.

libssh: avoid options override by configuration files

2020-04-24T22:53:11+00:00

Previously, options set explicitly through command line options could be
overridden by the configuration files parsed automatically when
ssh_connect() was called.

By calling ssh_options_parse_config() explicitly, the configuration
files are parsed before setting the options, avoiding the options
override.  Once the configuration files are parsed, the automatic
configuration parsing is not executed.

libssh: Use new ECDSA key types to check known hosts

2020-04-17T21:22:26+00:00

From libssh 0.9.0, ssh_key_type() returns different key types for ECDSA
keys depending on the curve.

libssh: Fix matching user-specified MD5 hex key

2020-03-07T08:06:11+00:00

Prior to this change a match would never be successful because it
was mistakenly coded to compare binary data from libssh to a
user-specified hex string (ie CURLOPT_SSH_HOST_PUBLIC_KEY_MD5).

libssh: improve known hosts handling

2020-02-27T09:03:07+00:00

Previously, it was not possible to get a known hosts file entry due to
the lack of an API.  ssh_session_get_known_hosts_entry(), introduced in
libssh-0.9.0, allows libcurl to obtain such information and behave the
same as when compiled with libssh2.

This also tries to avoid the usage of deprecated functions when the
replacements are available.  The behaviour will not change if versions
older than libssh-0.8.0 are used.

libssh2: fix variable type

2020-01-16T09:03:59+00:00

This led to a conversion warning on 64-bit MinGW, which has 32-bit
`long` but 64-bit `size_t`.
