Also:
- uppercase `(C)`.
- add missing 'All rights reserved.' lines.
- drop duplicate 'Author' lines.
- add copyright headers where missing.
- enable copyright header check in checksrc.
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
Twice. This tests are flaky and we haven't figured out why. In the
meantime use this workaround to test and log these issues, but also
ensure that CI run aren't flagged red because of it.
Also:
- kex: add debug message when hostkey `sig_verify` fails,
to help tracking WinCNG KEX failures.
- test_ssh2: also add retry logic.
I'm not quite sure this is correct. Please let me know.
- session_fixture: bump up `src_path` slots to fit retries and show
message when hitting the limit.
- session_fixture: clear `kbd_password` static variable after use.
- session_fixture: close and deinit socket after use.
- session_fixture: deinit libssh2 after use.
Ref: #804#846#979#1012#1015
Cherry-picked from #1017Closes#1023
Add macOS CI jobs, both cmake and autotools for all supported crypto
backends (except BoringSSL), with debug, zlib enabled. Without running
tests. It also introduces OpenSSL 1.1 into the CI with a non-MSVC
compiler.
Credits to curl's `macos.yml`, that I used as a base.
Fix these issues uncovered by the new tests:
- openssl: fix warning when built with wolfSSL, or OpenSSL 1.1 and
earlier. CI missed it because apparently the only OpenSSL 1.1 test
we had used MSVC, which did not complain.
```
../src/openssl.c:3852:19: error: variable 'sslError' set but not used [-Werror,-Wunused-but-set-variable]
unsigned long sslError;
^
```

- pem: add hack to build without MD5 crypto-backend support.
The Homebrew wolfSSL build comes with MD5 support disabled. We can
expect this becoming the norm. FIPS also requires MD5 disabled.
We deleted the same hack from `hostkey.c` a month ago:
ad6aae302a
A better fix would be to guard the MD5 logic with our `LIBSSH2_MD5`
macro.
```
pem.c:214:32: error: use of undeclared identifier 'MD5_DIGEST_LENGTH'; did you mean 'SHA_DIGEST_LENGTH'?
unsigned char secret[2*MD5_DIGEST_LENGTH];
^~~~~~~~~~~~~~~~~
SHA_DIGEST_LENGTH
```

- `configure.ac`: add crypto libs late.
Fix it by adding crypto libs to `LIBS` at the end of the configuration
process.
Otherwise `configure` links crypto libs while doing feature tests,
which can cause unwanted detections. For example LibreSSL publishes
the function `explicit_bzero()`, which masks the system alternative,
e.g. `memset_s()` on macOS. Then when trying to compile libssh2, its
declaration is missing:
```
bcrypt_pbkdf.c:93:5: error: implicit declaration of function 'explicit_bzero' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
_libssh2_explicit_zero(ciphertext, sizeof(ciphertext));
^
../src/misc.h:50:43: note: expanded from macro '_libssh2_explicit_zero'
^
```
Regression from 4f0f4bff5a
- cmake: fix to list our own include directory before the crypto libs',
when building tests.
Otherwise a global crypto header path, such as `/usr/local/include`,
containing an external `libssh2.h` of a different version, could cause
weird errors:
```

Closes#1013
- rename tests to have more succint names and a more useful natural
order.
- rename `simple` and `ssh2` in tests to have the `test_` prefix.
This avoids a name collisions with `ssh2` in examples.
- cmake: drop the `example-` prefix for generated examples.
Bringing their names in sync with other build tools, like autotools.
- move common auth test code into the fixture and simplify tests by
using that.
- move feature guards from CMake to preprocessor for auth tests.
Now it works with all build tools and it's easier to keep it in sync
with the lib itself.
For this we need to include `libssh2_priv.h` in tests, which in turn
needs tweaking on the trick we use to suppress extra MSVS warnings
when building tests and examples.
- move mbedTLS blocklist for crypto tests from CMake to the test
fixture.
- add ed25519 hostkey tests to `test_hostkey` and `test_hostkey_hash`.
- add shell script to regenerate all test keys used for our tests.
- alpha-sort tests.
- rename `signed_*` keys to begin with `key` like the rest of the keys
do.
- whitespace fixes.
Closes#969
- introduce the concept of a project level setup header
`src/libssh2_setup.h`, that is used by `src`, `example` and `tests`
alike. Move there all common platform/compiler configuration from
`src/libssh2_priv.h`, individual sources and `CMakeFiles.txt` files.
Also move there our hand-crafted (= not auto-generated by CMake or
autotools) configuration `win32/libssh2-config.h`.
- `win32` directory is empty now, delete it.
- `Makefile.mk`: adapt to the above. Build-directory is the target
triplet, or any custom name set via `BLD_DIR`.
- sync header path order between build systems:
build/src -> source/src -> source/include
- delete redundant references to `windows.h`, `winsock2.h`,
`ws2tcpip.h`.
- delete unnecessary #includes, update order (`libssh2_setup.h` first,
`winsock2.h` first), simplify where possible.
This makes the code warning-free without `WIN32_LEAN_AND_MEAN`.
At the same time this patch applies this macro globally, to avoid
header bloat.
- example: add missing *nix header guards.
- example: fix misindented `HAVE_UNISTD_H` `#ifdef`s.
- set `WIN32` with all build-tools.
- set `HAVE_SYS_PARAM_H` in the hand-crafted config for MinGW.
To match auto-detection.
- move a source-specific macro to `misc.c` from `libssh2_priv.h`.
See the PR's individual commits for step-by-step updates.
Closes#932
Before this patch, the `snprintf()` fallback logic for envs not
supporting this function (i.e. Visual Studio 2013 and older) varied
depending on build tool, and used different techniques in examples,
tests and libssh2 itself.
This patch aims to apply a common logic to libssh2 and examples/tests.
- libssh2: use local `snprintf()` fallback with all build tools.
We already had a local implementation, but only with CMake. Move that
to the library as `_libssh2_snprintf()`, and map `snprintf()` to it
when `HAVE_SNPRINTF` is not set.
Also change the length type from `int` to `size_t`, and fix
formatting.
- set or detect `HAVE_SNPRINTF` in non-CMake builds.
Detect in autotools. Keep existing logic in `win32/libssh2_config.h`.
Always set for OS/400, NetWare and VMS, keeping existing behaviour.
(OS/400 builds use a different local implementation)
- examples/tests: drop the CMake-specific fallback logic and map
`snprintf()` to `_snprintf()` for old MSVC versions, like we did
before with other build tools. This is unsafe, but should be fine for
these uses.
- `win32/libssh2_config.h`: make it easier to read.
Closes#812
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.
