12e1def51a sendf: change Curl_read_plain to wrap Curl_recv_plain
Prior to this change Curl_read_plain would attempt to read the
socket directly. On Windows that's a problem because recv data may be
cached by libcurl and that data is only drained using Curl_recv_plain.

Rather than rewrite Curl_read_plain to handle cached recv data, I
changed it to wrap Curl_recv_plain, in much the same way that
Curl_write_plain already wraps Curl_send_plain.

Curl_read_plain -> Curl_recv_plain
Curl_write_plain -> Curl_send_plain

This fixes a bug in the schannel backend where decryption of arbitrary
TLS records fails because cached recv data is never drained. We send
data (TLS records formed by Schannel) using Curl_write_plain, which
calls Curl_send_plain, and that may do a recv-before-send
("pre-receive") to cache received data. The code calls Curl_read_plain
to read data (TLS records from the server), which prior to this change
did not call Curl_recv_plain and therefore cached recv data wasn't
retrieved, resulting in malformed TLS records and decryption failure
(SEC_E_DECRYPT_FAILURE).

The bug has only been observed during Schannel TLS 1.3 handshakes. Refer
to the issue and PR for more information.

url: move back the IDN conversion of proxy names
Regression: in commit 53bcf55 we moved the IDN conversion calls to
happen before the HSTS checks. But the HSTS checks are only done on the
server host name, not the proxy names. By moving the proxy name IDN
conversions, we accidentally broke the verbose output showing the proxy
name.

This change moves back the IDN conversions for the proxy names to the
place in the code path they were before 53bcf55.

windows: fail early with a missing windres in autotools

Windows. When this happened, the build failed with a confusing error due

lib: sync guard for Curl_getaddrinfo_ex() definition and use
`Curl_getaddrinfo_ex()` gets _defined_ with `HAVE_GETADDRINFO` set. But,
`hostip4.c` _used_ it with `HAVE_GETADDRINFO_THREADSAFE` set alone. It
meant a build with the latter, but without the former flag could result
in calling this function but not defining it, and failing to link.

Patch this by adding an extra check for `HAVE_GETATTRINFO` around the
call.

Before this patch, build systems prevented this condition. Now they
don't need to.

While here, simplify the related CMake logic on Windows by setting
`HAVE_GETADDRINFO_THREADSAFE` to the detection result of
`HAVE_GETADDRINFO`. This expresses the following intent clearer than
the previous patch and keeps the logic in a single block of code:
When we have `getaddrinfo()` on Windows, it's always threadsafe.

tidy-up: process.h detection and use
This patch aims to cleanup the use of `process.h` header and the macro
`HAVE_PROCESS_H` associated with it.

- `process.h` is always available on Windows. In curl, it is required
  only for `_beginthreadex()` in `lib/curl_threads.c`.

- `process.h` is also available in MS-DOS. In curl, its only use was in
  `lib/smb.c` for `getpid()`. But `getpid()` is in fact declared by
  `unistd.h`, which is always enabled via `lib/config-dos.h`. So the
  header is not necessary.

- `HAVE_PROCESS_H` was detected by CMake, forced to 1 on Windows and
  left to real detection for other platforms.
  It was also set to always-on in `lib/config-win32.h` and
  `lib/config-dos.h`.
  In autotools builds, there was no detection and the macro was never
  set.

Based on these observations, in this patch we:

- Rework Windows `getpid` logic in `lib/smb.c` to always use the
  equivalent direct Win32 API function `GetCurrentProcessId()`, as we
  already did for Windows UWP apps. This makes `process.h` unnecessary
  here on Windows.

- Stop #including `process.h` into files where it was not necessary.
  This is everywhere, except `lib/curl_threads.c`.

  > Strangely enough, `lib/curl_threads.c` compiled fine with autotools
  > because `process.h` is also indirecty included via `unistd.h`. This
  > might have been broken in autotools MSVC builds, where the latter
  > header is missing.

- Delete all remaining `HAVE_PROCESS_H` feature guards, for they were
  unnecessary.

- Delete `HAVE_PROCESS_H` detection from CMake and predefined values
  from `lib/config-*.h` headers.

windows: fix linking .rc to shared curl with autotools
`./configure --enable-shared --disable-static` fails when trying to link
a shared `curl.exe`, due to `libtool` magically changing the output
filename of `windres` to one that it doesn't find when linking:

```
/bin/sh ../libtool --tag=RC --mode=compile windres -I../../curl/include -DCURL_EMBED_MANIFEST  -i ../../curl/src/curl.rc -o curl.o
libtool: compile:  windres -I../../curl/include -DCURL_EMBED_MANIFEST -i ../../curl/src/curl.rc  -o .libs/curl.o
[...]
CCLD     curl.exe
clang: error: no such file or directory: 'curl.o'
```

Let's resolve this by skipping `libtool` and calling `windres` directly
when building `src` (aka `curl.exe`). Leave `lib` unchanged, as it does
need the `libtool` magic. This solution is compatible with building
a static `curl.exe`.

This build scenario is not CI-tested.

While here, delete an obsolete comment about a permanent `libtool`
warning that we've resolved earlier.

cmake: really enable warnings with clang
Even though `PICKY_COMPILER=ON` is the default, warnings were not

This is the single use of this variable in curl, and in a different
place we already use `CMAKE_C_COMPILER_ID MATCHES "Clang"`, which works
as expected, so change the condition to use that instead.

Also fix the warnings uncovered by the above:

- lib: add casts to silence clang warnings

- schannel: add casts to silence clang warnings in ALPN code

  Assuming the code is correct, solve the warnings with a cast.
  This particular build case isn't CI tested.

winidn: drop WANT_IDN_PROTOTYPES
`WANT_IDN_PROTOTYPES` was necessary to avoid using a header that came

years ago and the winidn definitions are part of standard headers (via

Auto-detect Vista inside `lib/idn_win32.c` and enable the manual
definitions if building for an older Windows.

This allows to delete this manual knob from all build-systems.

Also drop the `_SAL_VERSION` sub-case:

Our manual definitions are now only enabled with old systems. We assume
that code analysis is not run on such systems, allowing us to delete the
SAL-friendly flavour of these.

3f5a7975a5 schannel: Don't reset recv/send function pointers on renegotiation
These function pointers will have been set when the initial TLS
handshake was completed. If they are unchanged, there is no need to set
them again. If they have been changed, as is the case with HTTP/2, we
don't want to override that change. That would result in the
http22_recv/send functions being completely bypassed.

Prior to this change a connection that uses Schannel with HTTP/2 would
fail on renegotiation with error "Received HTTP/0.9 when not allowed".

lib: set more flags in config-win32.h
The goal is to add any flag that affect the created binary, to get in
sync with the ones built with CMake and autotools.

I took these flags from curl-for-win [0], where they've been tested with
mingw-w64 and proven to work well.

This patch brings them to curl as follows:

- Enable unconditionally those force-enabled via
  `CMake/WindowsCache.cmake`:

  - `HAVE_SETJMP_H`
  - `HAVE_STRING_H`
  - `HAVE_SIGNAL` (CMake equivalent is `HAVE_SIGNAL_FUNC`)

- Expand existing guards with mingw-w64:

  - `HAVE_STDBOOL_H`
  - `HAVE_BOOL_T`

- Enable Win32 API functions for Windows Vista and later:

  - `HAVE_INET_NTOP`
  - `HAVE_INET_PTON`

- Set sizes, if not already set:

  - `SIZEOF_OFF_T = 8`
  - `_FILE_OFFSET_BITS = 64` when `USE_WIN32_LARGE_FILES` is set,
    and using mingw-w64.

- Add the remaining for mingw-w64 only. Feel free to expand as desired:

  - `HAVE_LIBGEN_H`
  - `HAVE_FTRUNCATE`
  - `HAVE_BASENAME`
  - `HAVE_STRTOK_R`

Future TODO:

- `HAVE_SIGNAL` has a different meaning in CMake. It's enabled when both
  the `signal()` function and the `SIGALRM` macro are found. In
  autotools and this header, it means the function only. For the
  function alone, CMake uses `HAVE_SIGNAL_FUNC`.

http: try parsing Retry-After: as a number first
Since the date parser allows YYYYMMDD as a date format (due to it being
a bit too generic for parsing this particular header), a large integer
number could wrongly match that pattern and cause the parser to generate
a wrong value.

No date format accepted for this header starts with a decimal number, so
by reversing the check and trying a number first we can deduct that if
that works, it was not a date.

Makefile.m32: drop CROSSPREFIX and our CC/AR defaults [ci skip]
This patch aimed to fix a regression [0], where `CC` initialization
moved beyond its first use. But, on closer inspection it turned out that
the `CC` initialization does not work as expected due to GNU Make
filling it with `cc` by default. So unless implicit values were
explicitly disabled via a GNU Make option, the default value of
`$CROSSPREFIX` + `gcc` was never used. At the same time the implicit
value `cc` maps to `gcc` in (most/all?) MinGW envs.

`AR` has the same issue, with a default value of `ar`.

We could reintroduce a separate variable to fix this without ill
effects, but for simplicity and flexibility, it seems better to drop
support for `CROSSPREFIX`, along with our own `CC`/`AR` init logic, and
require the caller to initialize `CC`, `AR` and `RC` to the full
(prefixed if necessary) names of these tools, as desired.

We keep `RC ?= windres` because `RC` is empty by default.

Also fix grammar in a comment.

1027d52e7d schannel: when importing PFX, disable key persistence
By default, the PFXImportCertStore API persists the key in the user's
key store (as though the certificate was being imported for permanent,

The documentation specifies that keys that are not to be persisted
should be imported with the flag PKCS12_NO_PERSIST_KEY.
NOTE: this flag is only supported on versions of Windows newer than XP
and Server 2003.

--

This is take 2 of the original fix. It extends the lifetime of the
client certificate store to that of the credential handle. The original
fix which landed in 70d010d and was later reverted in aec8d30 failed to
work properly because it did not do that.

Minor changes were made to the schannel credential context to support
closing the client certificate store handle at the end of an SSL session.

  - `-libssh` has build issues with BoringSSL and LibreSSL, and also
     what looks like a world-writable-config vulnerability on Windows.
     Consider it experimental.
  - `-psl` requires `-idn2` and extra libs passed via

- Detect BoringSSL/wolfSSL and set ngtcp2 crypto lib accordingly.
- Generalize MultiSSL detection.
- Use else-if syntax. Requires GNU Make 3.81 (2006-04-01).

websockets: remodeled API to support 63 bit frame sizes
curl_ws_recv() now receives data to fill up the provided buffer, but can
return a partial fragment. The function now also get a pointer to a
curl_ws_frame struct with metadata that also mentions the offset and
total size of the fragment (of which you might be receiving a smaller
piece). This way, large incoming fragments will be "streamed" to the
application. When the curl_ws_frame struct field 'bytesleft' is 0, the
final fragment piece has been delivered.

curl_ws_recv() was also adjusted to work with a buffer size smaller than
the fragment size. (Possibly needless to say as the fragment size can
now be 63 bit large).

curl_ws_send() now supports sending a piece of a fragment, in a
streaming manner, in addition to sending the entire fragment in a single
call if it is small enough. To send a huge fragment, curl_ws_send() can
be used to send it in many small calls by first telling libcurl about
the total expected fragment size, and then send the payload in N number
of separate invokes and libcurl will stream those over the wire.

The struct curl_ws_meta() returns is now called 'curl_ws_frame' and it
has been extended with two new fields: *offset* and *bytesleft*. To help
describe the passed on data chunk when a fragment is delivered in many
smaller pieces.

The documentation has been updated accordingly.

tidy-up: delete parallel/unused feature flags
Detecting headers and lib separately makes sense when headers come in
variations or with extra ones, but this wasn't the case here. These were
duplicate/parallel macros that we had to keep in sync with each other
for a working build. This patch leaves a single macro for each of these
dependencies:

- Rely on `HAVE_LIBZ`, delete parallel `HAVE_ZLIB_H`.

  Also delete CMake logic making sure these two were in sync, along with
  a toggle to turn off that logic, called `CURL_SPECIAL_LIBZ`.

  Also delete stray `HAVE_ZLIB` defines.

  There is also a `USE_ZLIB` variant in `lib/config-dos.h`. This patch
  retains it for compatibility and deprecates it.

- Rely on `USE_LIBSSH2`, delete parallel `HAVE_LIBSSH2_H`.

  Also delete `LIBSSH2_WIN32`, `LIBSSH2_LIBRARY` from
  `winbuild/MakefileBuild.vc`, these have a role when building libssh2
  itself. And `CURL_USE_LIBSSH`, which had no use at all.

Details:

- Change rules to create objects for the `v*` subdirs in the `lib` dir.
  This allows to use a shared compile rule and assumes that filenames
  are not (and will not be) colliding across these directories.
  `Makefile.m32` now also stores a list of these subdirs. They are
  changing rarely though.

- Sync as much as possible between the three `Makefile.m32` scripts'
  rules and their source/target sections.

- After this patch `CPPFLAGS` are all applied to the `src` sources once
  again. This matches the behaviour of cmake/autotools. Only zlib ones
  are actually required there.

- Use `.rc` names from `Makefile.inc` instead of keeping a duplicate.

- Change examples to link `libcurl.dll` by default. This makes building
  trivial, even as a cross-build:
    `CC=x86_64-w64-mingw32-gcc make -f Makefile.m32`
  To run them, you need to move/copy or add-to-path `libcurl.dll`.
  You can select static mode via `CFG=-static`.

- List more of the `Makefile.m32` config variables.

- Drop `.rc` support from examples. It made it fragile without much
  benefit.

- Include a necessary system lib for the `externalsocket.c` example.

- Exclude unnecessary systems libs when building in `-dyn` mode.

Makefile.m32: major rework [ci skip]
This patch overhauls `Makefile.m32` scripts, fixing a list of quirks,
making its behaviour and customization envvars align better with other
build systems, aiming for less code, that is easier to read, use and
maintain.

Details:
- Rename customization envvars:
  `CURL_CC` -> `CC`
  `CURL_RC` -> `RC`
  `CURL_AR` -> `AR`
  `CURL_LDFLAG_EXTRAS_DLL` -> `CURL_LDFLAGS_LIB`
  `CURL_LDFLAG_EXTRAS_EXE` -> `CURL_LDFLAGS_BIN`
- Drop `CURL_STRIP` and `CURL_RANLIB`. These tools are no longer used.
- Accept `CFLAGS`, `CPPFLAGS`, `RCFLAGS`, `LDFLAGS` and `LIBS` envvars.
- Drop `CURL_CFLAG_EXTRAS`, `CURL_LDFLAG_EXTRAS`, `CURL_RCFLAG_EXTRAS` in
  favor of the above.
- Do not automatically enable `zlib` with `libssh2`. `zlib` is optional
  with `libssh2`.
- Omit unnecessary `CPPFLAGS` options when building `curl.exe` and
  examples.
- Drop support for deprecated `-winssl` `CFG` option. Use `-schannel`
  instead.
- Avoid late evaluation where not necessary (`=` -> `:=`).
- Drop support for `CURL_DLL_A_SUFFIX` to override the implib suffix.
  Instead, use the standard naming scheme by default: `libcurl.dll.a`.
  The toolchain recognizes the name, and selects it automatically when
  asking for a `-shared` vs. `-static` build.
- Stop applying `strip` to `libcurl.a`. Follow-up from
  16a58e9f93. There was no debug info to
  strip since then.
- Stop setting `-O3`, `-W`, `-Wall` options. You can add these to
  `CFLAGS` as desired.
- Always enable `-DCURL_DISABLE_OPENSSL_AUTO_LOAD_CONFIG` with OpenSSL,
  to avoid that vulnerability on Windows.
- Add `-lbrotlicommon` to `LIBS` when using `brotli`.
- Do not enable `-nghttp3` without `-ngtcp2`.
- `-ssh2` and `-rtmp` options no longer try to auto-select a TLS-backend.
  You need to set the backend explicitly. This scales better and avoids
  issues with certain combinations (e.g. `libssh2` + `wolfssl` with no
  `schannel`).
- Default to OpenSSL TLS-backend with `ngtcp2`. Possible to override via
  `NGTCP2_LIBS`.
- Old, alternate method of enabling components (e.g. `SSH2=1`) no longer
  supported.
- Delete `SPNEGO` references. They were no-ops.
- Drop support for Win9x environments.
- Allow setting `OPENSSL_LIBS` independently from `OPENSSL_LIBPATH`.
- Support autotools/CMake `libssh2` builds by default.
- Respect `CURL_DLL_SUFFIX` in `-dyn` mode when building `curl.exe` and
  examples.
- Assume standard directory layout with `LIBCARES_PATH`. (Instead of the
  long gone embedded one.)
- Stop static linking with c-ares by default. Add
  `CPPFLAGS=-DCARES_STATICLIB` to enable it.
- Reorganize internal layout to avoid redundancy and emit clean diffs
  between src/lib and example make files.
- Delete unused variables.
- Code cleanups/rework.
- Comment and indentation fixes.

Makefile.m32: delete legacy component bits [ci skip]
- Drop auto-detection of OpenSSL 1.0.2 and earlier. Now always defaulting
  to OpenSSL 1.1.0 and later, LibreSSL and BoringSSL.

- Drop `Invalid path to OpenSSL package` detection. OpenSSL has been
  using a standard file layout since 1.1.0, so this seems unnecessary
  now.

- Drop special logic to enable Novell LDAP SDK support.

- Drop special logic to enable OpenLDAP LDAP SDK support. This seems
  to be distinct from native OpenLDAP, with support implemented inside
  `lib/ldap.c` (vs. `lib/openldap.c`) back when the latter did not exist
  yet in curl.

- Add `-lwldap32` only if there is no other LDAP library (either native
  OpenLDAP, or SDKs above) present.

- Update `doc/INSTALL.md` accordingly.

After this patch, it's necessary to make configration changes when using
OpenSSL 1.0.2 or earlier, or the two LDAP SDKs.

OpenSSL 1.0.2 and earlier:
```
export OPENSSL_INCLUDE = <path-to-openssl>/outinc
export OPENSSL_LIBPATH = <path-to-openssl>/out
export OPENSSL_LIBS = -lssl32 -leay32 -lgdi32
```

Novell LDAP SDK, previously enabled via `USE_LDAP_NOVELL=1`:
```
export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/inc -DCURL_HAS_NOVELL_LDAPSDK
export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib/mscvc -lldapsdk -lldapssl -lldapx
```

OpenLDAP LDAP SDK, previously enabled via `USE_LDAP_OPENLDAP=1`:
```
export CURL_CFLAG_EXTRAS = -I<path-to-sdk>/include -DCURL_HAS_OPENLDAP_LDAPSDK
export CURL_LDFLAG_EXTRAS = -L<path-to-sdk>/lib -lldap -llber
```

I haven't tested these scenarios, and in general we recommend using
a recent OpenSSL release. Also, WinLDAP (the Windows default) and
OpenLDAP (via `-DUSE_OPENLDAP`) are the LDAP options actively worked on
in curl.

- Delete related `WINIDN_PATH` option. IDN is a system lib since Vista.
- Sync `LIBCARES_PATH` default with the rest of dependencies.
- Delete version numbers from dependency path defaults.
- `libgsasl` package is now called `gsasl`.
- Delete `libexpat` and `libxml2` references. No longer used by curl.
- Delete `Edit the path below...` comments. We recommend to predefine
  those envvars instead.
- `libcares.a` is not an internal dependency anymore. Stop using it as
  such.
- `windres` `--include-dir` -> `-I`, `-F` -> `--target=` for readability.
- Delete `STRIP`, `CURL_STRIP`, `AR` references from `src/Makefile.m32`.
  They were never used.
- Stop to `clean` some objects twice in `src/Makefile.m32`.
- Delete cvs-specific leftovers.
- Finish resource support in examples make file.
- Delete `-I<root>/lib` from examples make file.
- Fix copyright start year in examples make file.
- Delete duplicate `ftpuploadresume` input in examples make file.
- Sync OpenSSL lib order, `SYNC` support, `PROOT` use, dependency path
  defaults, variables names and other internal bits between the three
  make files.
- `lib/Makefile.m32` accepted custom options via `DLL_LIBS` envvar. This
  was lib-specific and possibly accidental. Use `CURL_LDFLAG_EXTRAS_DLL`
  envvar for the same effect.
- Fix linking `curl.exe` and examples to wrong static libs with
  auto-detected OpenSSL 1.0.2 or earlier.
- Add `-lgdi32` for OpenSSL 1.0.2 and earlier only.
- Add link to Novell LDAP SDK and use a relative default path. Latest
  version is from 2016, linked to an outdated OpenSSL 1.0.1.
- Whitespace and comment cleanups.

LDAP SDK and the other LDAP SDK (which is _not_ OpenLDAP). Write up the
