will now be searched instead of just the first name.
- Update tool_operate.c to not search for the curl-ca-bundle.crt file
when using Schannel to maintain backward compatibility. Previously,
any curl-ca-bundle.crt file found in that search would have been
ignored by Schannel. But, with CAINFO support, the file found by
that search would have been used as the certificate store and
could cause issues for any users that have curl-ca-bundle.crt in
the search path.
- Update url.c to not set the build time CURL_CA_BUNDLE if the selected
SSL backend is Schannel. We allow setting CA location for schannel
only when explicitly specified by the user via CURLOPT_CAINFO /
--cacert.
- Add new test cases 3000 and 3001. These test cases check that the first
and last SAN, respectively, matches the connection hostname. New test
certificates have been added for these cases. For 3000, the certificate
prefix is Server-localhost-firstSAN and for 3001, the certificate
prefix is Server-localhost-secondSAN.
- Remove TODO 15.2 (Add support for custom server certificate
validation), this commit addresses it.

curl 7.57.0 and up interpret this according to Appendix E.3.2 of RFC
8089 but then returns an error saying this is unimplemented. This is
actually a regression in behavior on both Windows and Unix.
Before curl 7.57.0 this URL was treated as a path of "//foo/bar" and
then passed to the relevant OS API. This means that the behavior of this
case is actually OS dependent.
The Unix path resolution rules say that the OS must handle swallowing
the extra "/" and so this path is the same as "/foo/bar"
The Windows path resolution rules say that this is a UNC path and
automatically handles the SMB access for the program. So curl on Windows
was already doing Appendix E.3.2 without any special code in curl.

Originally, my idea was to allocate the two structures (or more
precisely, the connectdata structure and the four SSL backend-specific
strucutres required for ssl[0..1] and proxy_ssl[0..1]) in one go, so
that they all could be free()d together.
However, getting the alignment right is tricky. Too tricky.
So let's just bite the bullet and allocate the SSL backend-specific
data separately.

Prior to this change (since dev 70f1db3, release 7.56) the connectdata
structure was undersized by 4 bytes in 32-bit builds with ssl enabled
because long long * was mistakenly used for alignment instead of
long long, with the intention being an 8 byte boundary. Also long long
may not be an available type.
The undersized connectdata could lead to oob read/write past the end in
what was expected to be the last 4 bytes of the connection's secondary
socket https proxy ssl_backend_data struct (the secondary socket in a

When curl and libcurl are built with some protocols disabled, they stop
setting and receiving some options that don't make sense with those
protocols. In particular, when HTTP is disabled many options aren't set
that are used only by HTTP. However, some options that appear to be
HTTP-only are actually used by other protocols as well (some despite
having HTTP in the name) and should be set, but weren't. This change now
causes some of these options to be set and used for more (or for all)
protocols. In particular, this fixes tests 646 through 649 in an
HTTP-disabled build, which use the MIME API in the mail protocols.
A connection can only be reused if the flags "conn_to_host" and
"conn_to_port" match. Therefore it is not necessary to copy these flags
in reuse_conn().
Closes#1918
So far, all of the SSL backends' private data has been declared as
part of the ssl_connect_data struct, in one big #if .. #elif .. #endif
block.
This can only work as long as the SSL backend is a compile-time option,
something we want to change in the next commits.
Therefore, let's encapsulate the exact data needed by each SSL backend
into a private struct, and let's avoid bleeding any SSL backend-specific
information into urldata.h. This is also necessary to allow multiple SSL
backends to be compiled in at the same time, as e.g. OpenSSL's and
CyaSSL's headers cannot be included in the same .c file.
To avoid too many malloc() calls, we simply append the private structs
to the connectdata struct in allocate_conn().
This requires us to take extra care of alignment issues: struct fields
often need to be aligned on certain boundaries e.g. 32-bit values need to
be stored at addresses that divide evenly by 4 (= 32 bit / 8
bit-per-byte).
We do that by assuming that no SSL backend's private data contains any
fields that need to be aligned on boundaries larger than `long long`
(typically 64-bit) would need. Under this assumption, we simply add a
dummy field of type `long long` to the `struct connectdata` struct. This
field will never be accessed but acts as a placeholder for the four
instances of ssl_backend_data instead. the size of each ssl_backend_data
struct is stored in the SSL backend-specific metadata, to allow
allocate_conn() to know how much extra space to allocate, and how to
initialize the ssl[sockindex]->backend and proxy_ssl[sockindex]->backend
pointers.
This would appear to be a little complicated at first, but is really
necessary to encapsulate the private data of each SSL backend correctly.
And we need to encapsulate thusly if we ever want to allow selecting
CyaSSL and OpenSSL at runtime, as their headers cannot be included within
the same .c file (there are just too many conflicting definitions and
declarations for that).

When using basic-auth, connections and proxy connections

it does not authenticate the connection (like NTLM does).
For instance, the below command should re-use the proxy
connection, but it currently doesn't:
curl -v -U alice:a -x http://localhost:8181http://localhost/
--next -U bob:b -x http://localhost:8181http://localhost/
This is a regression since refactoring of ConnectionExists()
as part of: cb4e2be7c6
Fix the above by removing the username and password compare
when re-using proxy connection at proxy_info_matches().
However, this fix brings back another bug would make curl
to re-print the old proxy-authorization header of previous
proxy basic-auth connection because it wasn't cleared.
For instance, in the below command the second request should
fail if the proxy requires authentication, but would succeed
after the above fix (and before aforementioned commit):
curl -v -U alice:a -x http://localhost:8181http://localhost/
--next -x http://localhost:8181http://localhost/

define CURL_DISABLE_HTTP, and refactor to call detect_proxy() if not
define CURL_DISABLE_HTTP and the host is not in the noproxy list.
The combination of --noproxy option and http_proxy env var works well
both for proxied hosts and non-proxied hosts.
However, when combining NO_PROXY env var with --proxy option,
non-proxied hosts are not reachable while proxied host is OK.
This patch allows us to access non-proxied hosts even if using NO_PROXY
env var with --proxy option.
Follow-up to 3463408.
Prior to 3463408 file:// hostnames were silently stripped.
Prior to this commit it did not work when a schemeless url was used with
file as the default protocol.

Closes https://github.com/curl/curl/pull/1124
Also fix for drive letters:
- Support --proto-default file c:/foo/bar.txt
- Support file://c:/foo/bar.txt
- Fail when a file:// drive letter is detected and not MSDOS/Windows.

CURLOPT_SOCKS_PROXY -> CURLOPT_PRE_PROXY
Added the corresponding --preroxy command line option. Sets a SOCKS
proxy to connect to _before_ connecting to a HTTP(S) proxy.
This was added as part of the SOCKS+HTTPS proxy merge but there's no
need to support this as we prefer to have the protocol specified as a
prefix instead.
If a port number in a "connect-to" entry does not match, skip this
entry instead of connecting to port 0.
If a port number in a "connect-to" entry matches, use this entry
and look no further.
