4383a39d83 libssh2_channel_open: more detailed error message 
The error message returned by libssh2_channel_open in case of a server side channel open failure is now more detailed and includes the four standard error conditions in RFC 4254.

5a88a86fef configure.ac: check for SecureZeroMemory for clear memory feature 2015-04-03 16:44:53 +02:00
Marc Hoersken
0340d4586e Revert "wincng.c: fix clear memory feature compilation with mingw" 
This reverts commit 2d2744efdd0497b72b3e1ff6e732aa4c0037fc43.

Autobuilds show that this did not solve the issue.
And it seems like RtlFillMemory is defined to memset,
which would be optimized out by some compilers.

The OpenSSL define is OPENSSL_NO_BF, not OPENSSL_NO_BLOWFISH.

e160ba448e configure: error if explicitly enabled clear-memory is not supported 
This takes 22bd8d81d8fab956085e2079bf8c29872455ce59 and
b8289b625e291bbb785ed4add31f4759241067f3 into account,
but still makes it enabled by default if it is supported
and error out in case it is unsupported and was requested.

3d3347c062 scp.c: improved command length calculation 
Reduced number of calls to strlen, because shell_quotearg already
returns the length of the resulting string (e.q. quoted path)
which we can add to the existing and known cmd_len.
Removed obsolete call to memset again, because we can put a final
NULL-byte at the end of the string using the calculated length.

57dea4df6d wincng: Added explicit clear memory feature to WinCNG backend 
This re-introduces the original feature proposed during
the development of the WinCNG crypto backend. It still needs
to be added to libssh2 itself and probably other backends.

Memory is cleared using the function SecureZeroMemory which is
available on Windows systems, just like the WinCNG backend.

Missed a couple more places we init ctx to avoid openssl threading crash.

1de36eb5b4 Build build breakage in WinCNG backend caused when adding libssh2_userauth_publickey_frommemory. 
The new feature isn't implemented for the WinCNG backend currently, but the WinCNG backend didn't contain any implementation of the required backend functions - even ones that returns an error.  That caused link errors.

This change fixes the problem by providing an implementation of the backend functions that returns an error.

aa7f9a85f7 Fix breakage in WinCNG backend caused by introducing libssh2_hmac_ctx_init. 
The macro was defined to nothing for the libgcrypt backend, but not for WinCNG.  This brings the latter into line with the former.

14d9ee01bc Must init HMAC_CTX before using it. 
Must init ctx before using it or openssl will reuse the hmac which is not thread safe and causes a crash.

* Use an unimplemented error for extracting keys from memory with libgcrypt.

bbbdf946a7 Prevent collisions between CMake and Autotools in examples/ and tests/. 2015-03-13 07:47:41 +00:00
Alexander Lamaison
042993b8eb Avoid clash between CMake build and Autotools. 
Autotools expects a configuration template file at src/libssh2_config.h.in, which buildconf generates.  But the CMake build system has its CMake-specific version of the file at this path.  This means that, if you don't run buildconf, the Autotools build will fail because it configured the wrong header template.

See https://github.com/libssh2/libssh2/pull/8.
