- kex: drop unused assigment.
- knownhost: error when salt is NULL.
- mbedtls: avoid unnecessary inline assigments, that were ignored for
the second block and replaceable with a `ret = 0` initialization for
the first one.
- mbedtls: fix ignoring an API failure and ending up calling
`mbedtls_rsa_check_privkey()` unconditionally.
- misc: initialize datalen on error in `_libssh2_base64_decode()`.
- openssl: drop unused assigments.
- openssl: fix unused static function.
- packet: avoid NULL deref.
- packet: avoid NULL in `memcpy` src.
- publickey: optimize struct layout to avoid padding.
- sftp: replace ignored `rc` error assigment with `_libssh2_error()` call.
- transport: fix potential NULL ptr dereferences.
- transport: silence uninitialized value warnings.
- userauth: drop unused assigment.
- userauth: possible use of unitialized pointer.
- userauth: replace `rewind()` with `fseek()`.
`rewind()` returns an error condition in `errno`. `errno` is
problematic and reduces portability. Use `fseek()` to avoid it.
- userauth: replace potential NULL deref by returning error from
`sign_frommemory()`. Possible false positive. `rc` should be set
upstream if the callback is NULL.
- userauth: replace potential NULL deref by returning error from
`sign_fromfile()`. clang-tidy did not warn about this one, but
let's match `sign_frommemory()` anyway.
- wincng: fix potentially unused macros.
- wincng: make sure bignum is not NULL before use.
tests:
- openssh_fixture: drop unused assignment.
- session_fixture: exit if `username` not set, to avoid `strlen(NULL)`.
- session_fixture: replace `rewind()` with `fseek()`.
`rewind()` returns an error condition in `errno`. `errno` is
problematic and reduces portability. Use `fseek()` to avoid it.
- test_read: exit if `username` not set, to avoid `strlen(NULL)`.
examples:
- scp_write_nonblock: fix file handle leak.
- sftp_write_nonblock: file handle leak on error.
- sftp_write_sliding: file handle leak on error.
- ssh2_agent_forwarding: fix unused error codes.

Closes#1561
Cast large integer types to avoid dealing with printf masks for
`size_t` and other C99 types. Some of existing code used `int`
for this, bump them to `long`.
Ref: afa6b86560#1257Closes#1264
Instead of `WIN32`.
The compiler defines `_WIN32`. Windows SDK headers or build env defines
`WIN32`, or we have to take care of it. The agreement seems to be that
`_WIN32` is the preferred practice here.
Minor downside is that CMake uses `WIN32` and we also adopted it in
`Makefile.mk`.
In public libssh2 headers we stick with accepting either `_WIN32` or
`WIN32` and define our own namespaced `LIBSSH2_WIN32` based on them.
grepping for `WIN32` remains useful to detect Windows-specific code.
Closes#1195
Apply an existing fix to `test_read`, so that it falls back to use
the current username instead of the hardcoded `libssh2` when run
outside Docker.
This allows to run algo tests with this command:
```shell
cd tests
./test_sshd.test ./test_read_algos.test
```
Closes#1139
- All files have prominent copyright and SPDX identifier
- If not embedded in the file, in the .reuse/dep5 file
- All used licenses are in LICENSES/ (not shipped in tarballs)
- A new REUSE CI job verify that all files are OK

Closes#1084
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
Make the block count customizable in `test_read` via environment
`FIXTURE_XFER_COUNT`.
Set the custom count lower than the default when running on AppVeyor.
The goal is to reduce CI roundtrip times.
Closes#995
- 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
- fix skip auth if `userauthlist` is NULL.
Closes#836 (Reported-by: @sudipm-mukherjee on github)
- fix most silenced `checksrc` warnings.
- sync examples/tests code between each other.
(output messages, error handling, declaration order, comments)
- stop including unnecessary headers.
- always deinitialize in case of error.
- drop some redundant variables.
- add error handling where missing.
- show more error codes.
- switch `perror()` to `fprintf()`.
- fix some `printf()`s to be `fprintf()`.
- formatting.
Closes#960
- 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
Fix or silence all C compiler warnings discovered with (or without)
`PICKY_COMPILER=ON` (in CMake). This means all warnings showing up in
CI (gcc, clang, MSVS 2013/2015), in local tests on macOS (clang 14) and
Windows cross-builds using gcc (12) and llvm/clang (14/15).
Also fix the expression `nread -= nread` in `sftp_RW_nonblock.c`.
Cherry-picked from: #846Closes#861
Connects to the ssh server then downloads several MB of data. This
tests the data transfer path as well as boundary cases in packet
handling as data is split into smaller SSH blocks.
