This makes it possible to use specific compilers or a cache.
Sample use for clcache:
set CC=clcache.bat
nmake /f Makefile.vc DEBUG=no MODE=static VC=14 GEN_PDB=no
In the old line number 290, CC and CURL_CC had the same value. After
that, /DCURL_STATICLIB was added to CC but not CURL_CC (intended?).
This gets rid of the CC variable entirely. It is a first step to make it
possible to manualyl set a CC variable in order to be able to change the
compiler.
Updated the makefiles and Visual Studio project files to support moving
the authentication code to the new lib/vauth directory that was started
in commit 0d04e859e1.
Advise that WinSSL in versions <= XP will not be able to connect to
servers that no longer support the legacy handshakes and algorithms used
by those versions, and to use an alternate backend like OpenSSL instead.
Bug: https://github.com/bagder/curl/issues/253
Reported-by: zenden2k <zenden2k@gmail.com>
SSLeay was the name of the library that was subsequently turned into
OpenSSL many moons ago (1999). curl does not work with the old SSLeay
library since years. This is now reflected by only using USE_OPENSSL in
code that depends on OpenSSL.
Added support for a WITH_CARES option to be used when invoking nmake
via Makefile.vc. This option enables linking against both the DLL and
static versions of the c-ares libraries, as well as the debug and
release varients, depending on the value of DEBUG. The USE_ARES
preprocessor symbol is also defined.
I use the curl repo mainly on Windows with the typical Windows git
checkout which converts the LF line endings in the curl repo to CRLF
automatically on checkout. The automatic conversion is not done on files
in the repo with mixed line endings. I recently noticed some weird
output with projects/build-openssl.bat that I traced back to mixed line
endings, so I scanned the repo and there are files (excluding the
test data) that have mixed line endings.
I used this command below to do the scan. Unfortunately it's not as easy
as git grep, at least not on Windows. This gets the names of all the
files in the repo's HEAD, gets each of those files raw from HEAD, checks
for mixed line endings of both LF and CRLF, and prints the name if
mixed. I excluded path tests/data/test* because those can have mixed
line endings if I understand correctly.
for f in `git ls-tree --name-only --full-tree -r HEAD`;
do if [ -n "${f##tests/data/test*}" ];
then git show "HEAD:$f" | \
perl -0777 -ne 'exit 1 if /([^\r]\n.*\r\n)|(\r\n.*[^\r]\n)/';
if [ $? -ne 0 ];
then echo "$f";
fi;
fi;
done
This is just fundamentally broken. SPNEGO (RFC4178) is a protocol which
allows client and server to negotiate the underlying mechanism which will
actually be used to authenticate. This is *often* Kerberos, and can also
be NTLM and other things. And to complicate matters, there are various
different OIDs which can be used to specify the Kerberos mechanism too.
A SPNEGO exchange will identify *which* GSSAPI mechanism is being used,
and will exchange GSSAPI tokens which are appropriate for that mechanism.
But this SPNEGO implementation just strips the incoming SPNEGO packet
and extracts the token, if any. And completely discards the information
about *which* mechanism is being used. Then we *assume* it was Kerberos,
and feed the token into gss_init_sec_context() with the default
mechanism (GSS_S_NO_OID for the mech_type argument).
Furthermore... broken as this code is, it was never even *used* for input
tokens anyway, because higher layers of curl would just bail out if the
server actually said anything *back* to us in the negotiation. We assume
that we send a single token to the server, and it accepts it. If the server
wants to continue the exchange (as is required for NTLM and for SPNEGO
to do anything useful), then curl was broken anyway.
So the only bit which actually did anything was the bit in
Curl_output_negotiate(), which always generates an *initial* SPNEGO
token saying "Hey, I support only the Kerberos mechanism and this is its
token".
You could have done that by manually just prefixing the Kerberos token
with the appropriate bytes, if you weren't going to do any proper SPNEGO
handling. There's no need for the FBOpenSSL library at all.
The sane way to do SPNEGO is just to *ask* the GSSAPI library to do
SPNEGO. That's what the 'mech_type' argument to gss_init_sec_context()
is for. And then it should all Just Work™.
That 'sane way' will be added in a subsequent patch, as will bug fixes
for our failure to handle any exchange other than a single outbound
token to the server which results in immediate success.
Renamed the CURLX_ONES file list definition in order to a) try and be
consistent with other file lists and b) to allow for the addition of
the curlx header files, which will assist with Visual Studio project
files generation rather than hard coding those files.

Since Simple and Protected GSSAPI Negotiation Mechanism
is already implemented in curl and supported by the MinGW
builds, this change adds build support to winbuild makefiles.
Cleaned up order of handled build options by ordering them
nearly alphabetically by using the order of the generated
config name. Preparation for future/more build options.
Since WinSSL cannot be build without SSPI being enabled,
USE_WINSSL now defaults to the value of USE_SSPI.
The makefile does now raise an error if WinSSL is enabled
while SSPI is disabled.
Renamed external parameter USE_SSPI = yes/no to ENABLE_SSPI = yes/no.
Backwards compatible change: USE_SSPI can still be passed as external
parameter with yes/no value as long as ENABLE_SSPI is not given.
USE_x defines are passed around with true/false values internally,
USE_SSPI is now aligned to this approach, but still accepts external
values yes/no being passed, just like the other defines.
