Use Unix when generically writing about Unix based systems as UNIX is
the trademark and should only be used in a particular product's name.

There was a confusion between these: this commit tries to disambiguate them.
- Scope can be computed from the address itself.
- Scope id is scope dependent: it is currently defined as 1-based local
interface index for link-local scoped addresses, and as a site index(?) for
(obsolete) site-local addresses. Linux only supports it for link-local
addresses.
The URL parser properly parses a scope id as an interface index, but stores it
in a field named "scope": confusion. The field has been renamed into "scope_id".
Curl_if2ip() used the scope id as it was a scope. This caused failures
to bind to an interface.
Scope is now computed from the addresses and Curl_if2ip() matches them.
If redundantly specified in the URL, scope id is check for mismatch with
the interface index.
This commit should fix SF bug #1451.

It returns error for >= 400 HTTP responses.
Bug: https://github.com/bagder/curl/pull/129

The ability to do HTTP requests over a UNIX domain socket has been
requested before, in Apr 2008 [0][1] and Sep 2010 [2]. While a
discussion happened, no patch seems to get through. I decided to give it
a go since I need to test a nginx HTTP server which listens on a UNIX
domain socket.
One patch [3] seems to make it possible to use the
CURLOPT_OPENSOCKETFUNCTION function to gain a UNIX domain socket.
Another person wrote a Go program which can do HTTP over a UNIX socket
for Docker[4] which uses a special URL scheme (though the name contains
cURL, it has no relation to the cURL library).
This patch considers support for UNIX domain sockets at the same level
as HTTP proxies / IPv6, it acts as an intermediate socket provider and
not as a separate protocol. Since this feature affects network
operations, a new feature flag was added ("unix-sockets") with a
corresponding CURL_VERSION_UNIX_SOCKETS macro.
A new CURLOPT_UNIX_SOCKET_PATH option is added and documented. This
option enables UNIX domain sockets support for all requests on the
handle (replacing IP sockets and skipping proxies).
A new configure option (--enable-unix-sockets) and CMake option
(ENABLE_UNIX_SOCKETS) can disable this optional feature. Note that I
deliberately did not mark this feature as advanced, this is a
feature/component that should easily be available.

Initial implementation of the SMB/CIFS protocol.
|
|
Added the necessary protocol and port definitions in order to support
SMB/CIFS.
|
|
For consistency renamed USE_KRB5 to USE_KERBEROS5.
|
|
This variable is only used with HAVE_GSSAPI is defined by the FTP code
so let's place the definition with the other GSS-API based variables.

Reworked the input token (challenge message) storage as what is passed
to the buf and desc in the response generation are typically blobs of
data rather than strings, so this is more in keeping with other areas
of the SSPI code, such as the NTLM message functions.
|
|
|
|
When duplicating a handle, the data to post was duplicated using
strdup() when it could be binary and contain zeroes and it was not even
zero terminated! This caused read out of bounds crashes/segfaults.
Since the lib/strdup.c file no longer is easily shared with the curl
tool with this change, it now uses its own version instead.

Typically the USE_WINDOWS_SSPI definition would not be used when the
CURL_DISABLE_CRYPTO_AUTH define is, however, it is still a valid build
configuration and, as such, the SASL Kerberos V5 (GSSAPI) authentication
data structures and functions would incorrectly be used when they
shouldn't be.
Introduced a new USE_KRB5 definition that takes into account the use of
CURL_DISABLE_CRYPTO_AUTH like USE_SPNEGO and USE_NTLM do.
|
|
Its last use has been removed by the previous commit.

Option --pinnedpubkey takes a path to a public key in DER format and
only connect if it matches (currently only implemented with OpenSSL).
Provides CURLOPT_PINNEDPUBLICKEY for curl_easy_setopt().
Extract a public RSA key from a website like so:
openssl s_client -connect google.com:443 2>&1 < /dev/null | \
sed -n '/-----BEGIN/,/-----END/p' | openssl x509 -noout -pubkey \
| openssl rsa -pubin -outform DER > google.com.der

warning: extra tokens at end of #endif directive
|
|
Added a kerberos5data structure which is similar in nature to the
ntlmdata and negotiatedata structures.
|
|
Updated to use a dynamic buffer for the SPN generation via the recently
introduced Curl_sasl_build_spn() function rather than a fixed buffer of
1024 characters, which should have been more than enough, but by using
the new function removes the need for another variable sname to do the
wide character conversion in Unicode builds.
|
|
Given the SSPI package info query indicates a token size of 2888 bytes,
and as with the Winbind code and commit 9008f3d56, use a dynamic buffer
for the Type-1 and Type-3 message generation rather than a fixed buffer
of 1024 bytes.

- Replace CURLAUTH_GSSNEGOTIATE with CURLAUTH_NEGOTIATE
- CURL_VERSION_GSSNEGOTIATE is deprecated which
is served by CURL_VERSION_SSPI, CURL_VERSION_GSSAPI and
CURUL_VERSION_SPNEGO now.
- Remove display of feature 'GSS-Negotiate'
|
|
That auth mech has never existed neither on MS nor on Unix side.
There is only Negotiate over SPNEGO.
|
|
Otherwise NSS could use an already freed item for another connection.
|
|
|

|
|
Make all code use connclose() and connkeep() when changing the "close
state" for a connection. These two macros take a string argument with an
explanation, and debug builds of curl will include that in the debug
output. Helps tracking connection re-use/close issues.

In commit 0b3750b5c23c25f (released in 7.36.0) we fixed a timeout issue
but instead broke the timings.
To fix this, I introduce a new timestamp to use for the timeouts and
restored the previous timestamp and timestamp position so that the old
timer functionality is restored.
In addition to that, that change also broke connection timeouts for when
more than one connect was used (as it would then count the total time
from the first connect and not for the most recent one). Now
Curl_timeleft() has been modified so that it checks against different
start times depending on which timeout it checks.
Test 1303 is updated accordingly.

set.infilesize in this case was modified in several places, which could
lead to repeated requests using the same handle to get unintendent/wrong
consequences based on what the previous request did!

This makes the findprotocol() function work as intended so that libcurl
can properly be restricted to not support HTTP while still supporting
HTTPS - since the HTTPS handler previously set both the HTTP and HTTPS
bits in the protocol field.
This fixes --proto and --proto-redir for most SSL protocols.
This is done by adding a few new convenience defines that groups HTTP
and HTTPS, FTP and FTPS etc that should then be used when the code wants
to check for both protocols at once. PROTO_FAMILY_[protocol] style.

We're progressing throught drafts so there's no point in having a fixed
one in a symbol that'll survive.

In addition to FTP, other connection based protocols such as IMAP, POP3,
SMTP, SCP, SFTP and LDAP require a new connection when different log-in
credentials are specified. Fixed the detection logic to include these
other protocols.

Remove all #ifdef/else/endif macros that ensure compatibility with polarssl
version previous than 1.3.
|
|
Rename x509_cert to x509_crt and add "compat-1.2.h"
include.
This would still need some more thorough conversion
in order to drop "compat-1.2.h" include.

Port number zero is perfectly allowed to connect to. I moved to storing
the remote port number in an int so that -1 means undefined and 0-65535
can be used for legitimate port numbers.
|
|
Replaced the #define CURL_TIMEOUT_EXPECT_100 in transfer.c with the
CURLOPT_EXPECT_100_TIMEOUT_MS option to make the timeout configurable.
|

when using --http2 one can now selectively disable NPN or ALPN with
--no-alpn and --no-npn. for now honored with NSS only.
TODO: honor this option with GnuTLS and OpenSSL
