Changelog for the libssh2 project. Generated with git2news.pl

Version 1.8.0 (25 Oct 2016)

Daniel Stenberg (25 Oct 2016)
- RELEASE-NOTES: adjusted for 1.8.0

Kamil Dudka (20 Oct 2016)
- Revert "aes: the init function fails when OpenSSL has AES support"
  
  This partially reverts commit f4f2298ef3635acd031cc2ee0e71026cdcda5864
  because it caused the compatibility code to call initialization routines
  redundantly, leading to memory leakage with OpenSSL 1.1 and broken curl
  test-suite in Fedora:
  
  88 bytes in 1 blocks are definitely lost in loss record 5 of 8
     at 0x4C2DB8D: malloc (vg_replace_malloc.c:299)
     by 0x72C607D: CRYPTO_zalloc (mem.c:100)
     by 0x72A2480: EVP_CIPHER_meth_new (cmeth_lib.c:18)
     by 0x4E5A550: make_ctr_evp.isra.0 (openssl.c:407)
     by 0x4E5A8E8: _libssh2_init_aes_ctr (openssl.c:471)

libssh2_wait_socket: Fix comparison with api_timeout to use milliseconds (#134)
  
  Fixes #74

- [Charles Collicutt brought this change]

Set err_msg on _libssh2_wait_socket errors (#135)

- Revert "travis: Test mbedtls too"
  
  This reverts commit 3e6de50a24815e72ec5597947f1831f6083b7da8.
  
  Travis doesn't seem to support the mbedtls-dev package

- maketgz: support "only" to only update version number locally
  
  and fix the date output locale

- configure: make the --with-* options override the OpenSSL default
  
  ... previously it would default to OpenSSL even with the --with-[crypto]
  options used unless you specificly disabled OpenSSL. Now, enabling another
  backend will automatically disable OpenSSL if the other one is found.

docs: Add documentation on new cmake/configure options

configure: Add support for building with mbedtls

Basic dockerised test suite.
  
  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.

Fix MSVC 14 compilation errors
  
  For _MSC_VER == 1900 these macros are not needed and create problems:
  
  
  
  1>C:\Program Files (x86)\Windows Kits\10\Include\10.0.10240.0\ucrt\stdio.h(1925): warning C4005: 'snprintf': macro redefinition (compiling source file libssh2-files\src\mac.c)

_libssh2_channel_open: speeling error fixed in channel error message

Alexander Lamaison (15 Mar 2016)
- Link with crypt32.lib on Windows.
  
  Makes linking with static OpenSSL work again.  Although it's not
  required for dynamic OpenSSL, it does no harm.
  
  Fixes #98.

- [Craig A. Berry brought this change]

Tweak VMS help file building.
  
  Primarily this is handling cases where top-level files moved into
  the docs/ directory.  I also corrected a typo and removed the
  claim that libssh2 is public domain.

- [Craig A. Berry brought this change]

Build with standard stat structure on VMS.
  
  This gets us large file support, is available on any VMS release
  in the last decade and more, and gives stat other modern features
  such as 64-bit ino_t.

- [Craig A. Berry brought this change]

Update vms/libssh2_config.h.
  
  VMS does have stdlib.h, gettimeofday(), and OpenSSL.  The latter
  is appropriate to hard-wire in the configuration because it's
  installed by default as part of the base operating system and
  there is currently no libgcrypt port.

- [Craig A. Berry brought this change]

VMS can't use %zd for off_t format.
  
  %z is a C99-ism that VMS doesn't currently have; even though the
  compiler is C99-compliant, the library isn't quite.  The off_t used
  for the st_size element of the stat can be 32-bit or 64-bit, so
  detect what we've got and pick a format accordingly.

- [Craig A. Berry brought this change]

Normalize line endings in libssh2_sftp_get_channel.3.
  
  Somehow it got Windows-style CRLF endings so convert to just LF,
  for consistency as well as not to confuse tools that will regard
  the \r as content (e.g. the OpenVMS help librarian).

Alexander Lamaison (18 Feb 2016)
- Allow CI failures with VS 2008 x64.
  
  Appveyor doesn't support this combination.

- [Viktor Szakats brought this change]

GNUmakefile: list system libs after user libs
  
  Otherwise some referenced WinSock functions will fail to
  resolve when linking against LibreSSL 2.3.x static libraries
  with mingw.
  
  Closes #80

- [Viktor Szakats brought this change]

openssl: apply new HAVE_OPAQUE_STRUCTS macro
  
  Closes #81

openssl: fix LibreSSL support after OpenSSL 1.1.0-pre1/2 support

Alexander Lamaison (14 Feb 2016)
- sftp.h: Fix non-C90 type.
  
  uint64_t does not exist in C90.  Use libssh2_uint64_t instead.

- Exclude sshd tests from AppVeyor.
  
  They fail complaining that sshd wasn't invoked with an absolute path.

- Test on more versions of Visual Studio.

- Fix Appveyor builds.

Daniel Stenberg (14 Feb 2016)
- [Viktor Szakats brought this change]

openssl: add OpenSSL 1.1.0-pre3-dev compatibility
  
  by using API instead of accessing an internal structure.
  
  Closes #83

- RELEASE-NOTES: synced with 996b04ececdf

- include/libssh2.h: next version is 1.7.0

- configure: build "silent" if possible

- sftp: re-indented some minor stuff

- [Jakob Egger brought this change]

sftp.c: ensure minimum read packet size
  
  For optimum performance we need to ensure we don't request tiny packets.

- [Jakob Egger brought this change]

sftp.c: Explicit return values & sanity checks

- [Jakob Egger brought this change]

sftp.c: Check Read Packet File Offset
  
  This commit adds a simple check to see if the offset of the read
  request matches the expected file offset.
  
  We could try to recover, from this condition at some point in the future.
  Right now it is better to return an error instead of corrupted data.

- [Jakob Egger brought this change]

sftp.c: Don't return EAGAIN if data was written to buffer

- [Jakob Egger brought this change]

sftp.c: Send at least one read request before reading
  
  This commit ensures that we have sent at least one read request before
  we try to read data in sftp_read().
  
  Otherwise sftp_read() would return 0 bytes (indicating EOF) if the
  socket is not ready for writing.

- [Jakob Egger brought this change]

sftp.c: stop reading when buffer is full
  
  Since we can only store data from a single chunk in filep,
  we have to stop receiving data as soon as the buffer is full.
  
  This adresses the following bug report:
  https://github.com/libssh2/libssh2/issues/50

Salvador FandiÃ±o (21 Jan 2016)
- agent_disconnect_unix: unset the agent fd after closing it
  
  "agent_disconnect_unix", called by "libssh2_agent_disconnect", was
  leaving the file descriptor in the agent structure unchanged. Later,
  "libssh2_agent_free" would call again "libssh2_agent_disconnect" under
  the hood and it would try to close again the same file descriptor. In
  most cases that resulted in just a harmless error, but it is also
  possible that the file descriptor had been reused between the two
  calls resulting in the closing of an unrelated file descriptor.
  
  This patch sets agent->fd to LIBSSH2_INVALID_SOCKET avoiding that
  issue.
