Closes https://github.com/curl/curl/pull/3037
Allow to ovverride certain build tools, making it possible to
use LLVM/Clang to build curl. The default behavior is unchanged.
To build with clang (as offered by MSYS2), these settings can
be used:
CURL_CC=clang
CURL_AR=llvm-ar
CURL_RANLIB=llvm-ranlib
Closes https://github.com/curl/curl/pull/1993
- New `CURL_DLL_SUFFIX` envvar will add a suffix to the generated
libcurl dll name. Useful to add `-x64` to 64-bit builds so that
it can live in the same directory as the 32-bit one. By default
this is empty.
- New `CURL_DLL_A_SUFFIX` envvar to customize the suffix of the
generated import library (implib) for libcurl .dll. It defaults
to `dll`, and it's useful to modify that to `.dll` to have the
standard naming scheme for mingw-built .dlls, i.e. `libcurl.dll.a`.
Closes https://github.com/curl/curl/pull/1942
libidn was replaced with libidn2 last year in configure.
Caveat: libidn2 may depend on a list of further libs.
These can be manually specified via CURL_LDFLAG_EXTRAS.
Closes https://github.com/curl/curl/pull/1815
When this define was set, libcurl would check the environment variable
named CURL_CA_BUNDLE at run-time and use that CA cert bundle. This
feature was only defined by the watcom and m32 makefiles and caused
inconsistent behaviours among libcurls built on different platforms.
The curl tool does already feature its own similar logic and the library
does not really need it, and it isn't documented libcurl behavior. So
this change removes it.
Ref: #1538
In makefile.m32, option -ssh2 (libssh2) automatically implied -ssl
(OpenSSL) option, with no way to override it with -winssl. Since both
libssh2 and curl support using Windows's built-in SSL backend, modify
the logic to allow that combination.
- update default versions of dependencies (except for rare/old platforms)
- update urls
- sync examples makefiles with main ones
- remove line ending space
Add 'gdi32' and 'crypt32' Windows implibs to avoid failure
while building libcurl.dll using the mingw compiler.
The same logic is used in 'src/makefile.m32' when
building curl.exe.
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.
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.
Version number is removed in order to make this info consistent with
how we do it with other MS and Linux system libraries for which we don't
provide this info.
Identifier changed from 'WinSSPI' to 'schannel' given that this is the
actual provider of the SSL/TLS support. libcurl can still be built with
SSPI and without SCHANNEL support.
