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.
%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.
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).
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.
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.
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
"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.

The Qc3 library is not able to handle PKCS#8 EncryptedPrivateKeyInfo structures
by itself. It is only capable of decrypting the (encrypted) PrivateKeyInfo
part, providing a key encryption key and an encryption algorithm are given.
Since the encryption key and algorithm description part in a PKCS#8
EncryptedPrivateKeyInfo is a PKCS#5 structure, such a decoder is needed to
get the derived key method and hash, as well as encryption algorith and
initialisation vector.
The Qc3 library requires a minimum key length depending on the target
hash algorithm. Append binary zeroes to the given key if not long enough.
This matches RFC 2104 specifications.
The Qc3 library requires the key encryption key to exist as long as
the encrypted key is used. Its descriptor token is then kept as an
"encrypted key slave" for recursive release.
Build procedure extproto() did not strip braces from header files, thus
possibly prepended them to true prototypes. This prevented the prototype to
be recognized as such.
The solution implemented here is to map braces to semicolons, effectively
considering them as potential prototype delimiters.
In addition, file os400/macros.h declares all procedures originally
defined as macros. It must not be used for real inclusion and is only
intended to be used as a `database' for macro wrapping procedures generation.
Some structure fields holding callback addresses have the same name as the
underlying system function (connect, send, recv). Set parentheses around
their reference to suppress a possible macro substitution.
Use a macro for connect() on OS/400 to resolve a const/nonconst parameter
problem.
