Reasons for deleting years (copied as-is from curl):
- they are mostly pointless in all major jurisdictions
- many big corporations and projects already don't use them
- saves us from pointless churn
- git keeps history for us
- the year range is kept in COPYING
Closes#1082
Make sure these files get LF newlines on checkout. Before this patch
a checked out libssh2 Git repository may have used CRLF newlines in text
files, include test keys. Private keys with CRLF newlines could confuse
sshd on Windows:
```
# sshd version: 'OpenSSH_9.2, OpenSSL 1.1.1t 7 Feb 2023'
Unable to load host key "/d/a/libssh2/libssh2/tests/openssh_server/ssh_host_ed25519_key": invalid format
Unable to load host key: /d/a/libssh2/libssh2/tests/openssh_server/ssh_host_ed25519_key

Cherry-picked from #1017
- add #included C files to `EXTRA_DIST`.
Regression from 4f0f4bff5a
- fix `tests/sshd_fixture.sh` to not write into the test dir, by using
a pre-assembled `TrustedUserCAKeys` file. Update `Dockerfile` too to
use this.
Regression from a459a25302
Also update `tests/sshd_fixture.sh` to use
`openssh_server/authorized_keys` like `Dockerfile` does. And a few more
cosmetic updates.
Closes#1006
TL;DR: Sync test builds between autotools and CMake. Sync sshd
configuration between Docker and non-Docker fixtures. Bump up
sshd_config for recent OpenSSH releases.
This also opens up the path to have non-Docker tests that use a
local sshd process. Though sshd is practically unusable on Windows
CI machines out of the box, so this will need further efforts.
Details:
- cmake: run sshd fixture test just like autotool did already.
- sync tests and their order between autotools and CMake.
It makes `test_aa_warmup` the first test with both.
- cmake: load test lists from `Makefile.am`.
Needed to update the loader to throw away certain lines to keep the
converted output conform CMake syntax. Using regexp might be an
alternative way of doing this, but couldn't make it work.
- cmake: use the official way to configure test environment variables.
Switch to syntax that's extendable.
- cmake: allow to run the same test both under Docker and sshd fixture.
Useful for testing the sshd fixture runner, or how the same test
behaves in each fixture.
- update test fixture to read the username from `USER` envvar instead of
using the Dockfile-specific hardwired one, when running outside Docker.
- rework `ssh2.sh` into `sshd_fixture.sh`, to:
- allow running any tests (not just `test_ssh2`).
- configure Docker tests for running outside Docker.
- fixup `SSHD` path when running on Windows (e.g. in AppVeyor CI).
Fixes: `sshd re-exec requires execution with an absolute path`
- allow overriding `PUBKEY` and `PRIVKEY` envvars.
- allow overriding `ssh_config` via `SSHD_FIXTURE_CONFIG`.
- prepare support for running multiple tests via sshd_fixture.
Add a TAP runner for autotools and extend CMake logic. The TAP runner
loads the test list from `Makefile.am`.
Notice however that on Windows, `sshd_fixture.sh` is very flaky with
GitHub Actions. And consistently broken for subsequent tests in
AppVeyor CI:
'libssh2_session_handshake failed (-43): Failed getting banner'
Another way to try is a single sshd instance serving all tests.
For CMake this would probably mean using an external script.
- ed25519 test keys were identical for auth and host. Regenerate the
auth keypair to make them distinct.
- sync the sshd environment between Docker and sshd_fixture.
- use common via `openssh_server/sshd_config`.
- accept same auth keys.
- offer the same host keys.
- sync TrustedUserCAKeys.
- delete now unused keypairs: `etc/host*`, `etc/user*`.
- bump up startup delay for Windows (randomly, to 5 secs, from 3).
- delete `UsePrivilegeSeparation no` to avoid deprecation warnings.
`command-line line 0: Deprecated option UsePrivilegeSeparation`
- delete `Protocol 2` to avoid deprecation warnings.
It has been the default since OpenSSH 3.0 (2001-11-06).
- delete `StrictModes no` (CI tests work without it, Docker tests
never used it).
- bump `Dockerfile` base image to `testing-slim` (from `bullseye-slim`).
It needed `sshd_config` updates to keep things working with
OpenSSH 9.2 (compared to bullseye's 8.4).
- replace `ChallengeResponseAuthentication` alias with
`KbdInteractiveAuthentication`.
The former is no longer present in default `sshd_config` since
OpenSSH 8.7 (2021-08-20). This broke the `Dockerfile` script.
The new name is documented since OpenSSH 4.9 (2008-03-31)
- add `PubkeyAcceptedKeyTypes +ssh-rsa,ssh-dss,ssh-rsa-cert-v01@openssh.com`
and `HostKeyAlgorithms +ssh-rsa`.
Original-patch-by: Eric van Gyzen (@vangyzen on github)
Fixes#691
There is a new name for `PubkeyAcceptedKeyTypes`:
`PubkeyAcceptedAlgorithms`.
It requires OpenSSH 8.5 (2021-03-03) and breaks some envs so we're
not using it just yet.
- drop `rijndael-cbc@lysator.liu.se` tests and references from config.
This is a draft alias for `aes256-cbc`. No need to test it twice.
Also this alias is no longer recognized by OpenSSH 8.5 (2021-03-03).
- update `mansyntax.sh` and `sshd_fixture.sh` to not rely on `srcdir`.
Hopefully this works with out-of-tree builds.
- fix `test_read_algos.test` to honor CRLF EOLs in their inputs
(necessary when running on Windows.)
- fix `test_read_algos.test` to honor `EXEEXT`. Might be useful when
running tests under cross-builds?
- `test_ssh2.c`:
- use libssh2 API to set blocking mode. This makes it support all
platforms.
- adapt socket open timeout logic from `openssh_fixture.c`.
Sadly this did not help fix flakiness on GHA Windows.
- tests: delete unused C headers and variable initialization.
- delete unused test files: `sshd_fixture.sh.in`, `sshdwrap`,
`etc/sshd_config`.
Ref: cf80f2f4b5
- autotools: delete stray `.c` test sources from `EXTRA_DIST` in tests.
- `tests/.gitignore`: drop two stray tests.
- autotools: fix passing `SSHD` containing space (Windows needs this).
- autotools: sort `EXTRA_DIST` in tests.
- cmake: fix to add `test_ssh2` to `TEST_TARGETS`.
- fix `authorized_key` order in `tests/gen_keys.sh`.
- silence shellcheck warning in `ci/checksrc.sh`.
- set `SSHD` for autotools on GitHub Actions Windows. [skipped]
Auto-detection doesn't work (maybe because sshd is installed via
Git for Windows and we're using MSYS2's shell.)
It enables running sshd fixture (non-Docker) tests in these jobs.
I did not include this in the final patch due to flakiness:
```
Connection to 127.0.0.1:4711 attempt #0 failed: retrying...
Connection to 127.0.0.1:4711 attempt #1 failed: retrying...
Connection to 127.0.0.1:4711 attempt #2 failed: retrying...
Failure establishing SSH session: -43
```
Can be enabled with:
`export SSHD='C:/Program Files/Git/usr/bin/sshd.exe'`

OpenSSH Key and ED25519 support #39
Added _libssh2_explicit_zero() to explicitly zero sensitive data in memory #120
* ED25519 Key file support - Requires OpenSSL 1.1.1 or later
* OpenSSH Key format reading support - Supports RSA/DSA/ECDSA/ED25519 types
* New string buffer reading functions - These add build-in bounds checking and convenance methods. Used for OpenSSL PEM file reading.
* Added new tests for OpenSSH formatted Keys
This commit lands full ECDSA key support when using the OpenSSL
backend. Which includes:
New KEX methods:
ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521
Can now read OpenSSL formatted ECDSA key files.
Now supports known host keys of type ecdsa-sha2-nistp256.
New curve types:
NID_X9_62_prime256v1, NID_secp384r1, NID_secp521r1
Default host key preferred ordering is now nistp256, nistp384,
nistp521, rsa, dss.

This introduces a test suite for libssh2. It runs OpenSSH in a Docker
container because that works well on Windows (via docker-machine) as
well as Linux. Presumably it works on Mac too with docker-machine, but
I've not tested that.
Because the test suite is docker-machine aware, you can also run it
against a cloud provider, for more realistic network testing, by setting
your cloud provider as your active docker machine. The Appveyor CI setup
in this commit does that because Appveyor doesn't support docker
locally.
