  curl 7.85.0 release

- THANKS: add contributors from the 7.85.0 release

- getparam: correctly clean args

  Follow-up to bf7e887b2442783ab52

  The previous fix for #9128 was incomplete and caused #9397.

  Fixes #9397
  Closes #9399

- zuul: remove the clang-tidy job

  Turns out we don't see the warnings, but the warnings right now are
  plain ridiculous and unhelpful so we can just as well just kill this
  job.

  Closes #9390

- cmake: set feature PSL if present

  ... make test 1014 pass when libpsl is used.

  Closes #9391

- lib530: simplify realloc failure exit path

  Closes #9392

- [Orgad Shaneh brought this change]

  tests: add tests for netrc login/password combinations

  Covers the following PRs:

  - #9066
  - #9247
  - #9248

  Closes #9256

- [Orgad Shaneh brought this change]

  url: really use the user provided in the url when netrc entry exists

  If the user is specified as part of the URL, and the same user exists
  in .netrc, Authorization header was not sent at all.

  The user and password fields were assigned in conn->user and password
  but the user was not assigned to data->state.aptr, which is the field
  that is used in output_auth_headers and friends.

  Fix by assigning the user also to aptr.

  Amends commit d1237ac906ae7e3cd7a22c3a2d3a135a97edfbf5.

  Fixes #9243

- [Orgad Shaneh brought this change]

  netrc: Use the password from lines without login

  If netrc entry has password with empty login, use it for any username.

  Example:
  .netrc:
  machine example.com password 123456

  curl -vn http://[email protected]/

  Fix it by initializing state_our_login to TRUE, and reset it only when
  finding an entry with the same host and different login.

  Closes #9248

- [Jay Satiro brought this change]

  url: treat missing usernames in netrc as empty

  - If, after parsing netrc, there is a password with no username then
    set a blank username.

  This used to be the case prior to 7d600ad (precedes 7.82). Note
  parseurlandfillconn already does the same thing for URLs.

- libssh: ignore deprecation warnings

  libssh 0.10.0 marks all SCP functions as "deprecated" which causes
  compiler warnings and errors in our CI jobs and elsewhere. Ignore
  deprecation warnings if 0.10.0 or later is found in the build.

  If they actually remove the functions at a later point, then someone can
  deal with that pain and functionality break then.

- Revert "schannel: when importing PFX, disable key persistence"

  This reverts commit 70d010d285315e5f1cad6bdb4953e167b069b692.

  Due to further reports in #9300 that indicate this commit might
  introduce problems.

- multi: use larger dns hash table for multi interface

  Have curl_multi_init() use a much larger DNS hash table than used for
  the easy interface to scale and perform better when used with _many_
  host names.

  curl_share_init() sets an in-between size.

- Makefile.m32: allow -nghttp3/-ngtcp2 without -ssl [ci skip]

  Before this patch `-nghttp3`/`-ngtcp2` had an effect only when `-ssl`
  was also enabled. `-ssl` meaning OpenSSL (and its forks). After
  8a13be227eede2601c2b3b1c63e08b3dc9b35dd5 nghttp3/ngtcp2 can also be
  used together with wolfSSL. This patch adds the ability to enable
  `-nghttp3`/`-ngtcp2` independently from `-ssl` (OpenSSL), allowing to
  use it with wolfSSL or other, future TLS backends.

  Before this patch, it was fine to enable `-nghttp3`/`-ngtcp2`
  unconditionally. After this patch, this is no longer the case, and now
  it's the user's responsibility to enable `-nghttp3`/`-ngtcp2` only
  together with a compatible TLS backend.

  When using a TLS backend other than OpenSSL, the TLS-specific ngtcp2
  library must be configured manually, e.g.:
    `export CURL_LDFLAG_EXTRAS=-lngtcp2_crypto_wolfssl`

  (or via `NGTCP2_LIBS`)

  The slow performance has two causes:
  1. Use of a regex locale operator
  2. Useless invokations of loops

  The commit addresses the first issue by replacing the "\W" wiht
  [^a-zA-Z0-9_], which is, according to regex101.com, functionally
  equivalent to the previous operation, except that it is obviously
  limited to ASCII only, which is fine, as the curl project is
  English-only anyway.

  The second issue is being addressed by only running the loop if the line
  contains a "--" in it. The loop may be completeley removed in the
  future.

  curl-functions.m4: check whether atomics can link rather than just compile

  Some build toolchains support C11 atomics (i.e., _Atomic types), but
  will not link the associated atomics runtime unless a flag is passed. In
  such an environment, linking an application with libcurl.a can fail due
  to undefined symbols for atomic load/store functions.

  I encountered this behavior when upgrading curl to 7.84.0 and attempting
  to build with Solaris Studio 12.6. Solaris provides the flag
  -xatomic=[gcc | studio], allowing users to link to one of two atomics
  runtime implementations. However, if the user does not provide this
  flag, then neither runtime is linked. This led to builds failing in CI.

- Makefile.m32: stop trying to build libcares.a [ci skip]

  Before this patch, `lib/Makefile.m32` had a rule to build `libcares.a` in
  `-cares`-enabled builds, via c-ares's own `Makefile.m32`. Committed in
  2007 [1]. The commit message doesn't specifically address this particular
  change. This logic comes from the times when c-ares was part of the curl
  source tree, hence the special treatment.

  This feature creates problems when building c-ares first, using CMake
  and pointing `LIBCARES_PATH` to its install prefix, where `Makefile.m32`
  is missing in such case. A sub-build for c-ares is undesired also when
  c-ares had already been build via its own `Makefile.m32`.

  To avoid the sub-build, this patch deletes its Makefile rule. After this
  patch `libcares.a` needs to be manually built before using it in
  `Makefile.m32`. Aligning it with the rest of dependencies.

- build: improve OS string in CMake and `config-win32.h`

  This patch makes CMake fill the "OS string" with the value of
  `CMAKE_C_COMPILER_TARGET`, if passed. This typically contains a triplet,
  the same we can pass to `./configure` via `--host=`.

  For non-CMake, non-autotools, Windows builds, this patch adds the ability
  to override the default `OS` value in `lib/config-win32.h`.

  With these its possible to get the same OS string across the three build
  systems.

  This patch supersedes the earlier, partial, CMake-only solution:
  435f395f3f8c11eebfcc243ca55ebcc11a19b8b8, thus retiring the
  `CURL_OS_SUFFIX` CMake option.

  `CURL_RC` comes handy when using LLVM tools with `CROSSPREFIX=llvm-` and
  `CURL_CC=clang` set on current latest debian:unstable or earlier, where
  `llvm-windres` is missing, and a `CURL_RC=<triplet>-windres` fixes it.

- openssl: add `CURL_BORINGSSL_VERSION` to identify BoringSSL

  BoringSSL doesn't keep a version number, and doesn't self-identify itself
  via any other revision number via its own headers. We can identify
  BoringSSL revisions by their commit hash. This hash is typically known by
  the builder. This patch adds a way to pass this hash to libcurl, so that
  it can display in the curl version string:

  For example:

  `CFLAGS=-DCURL_BORINGSSL_VERSION="c239ffd0"`

  ```
  curl 7.84.0 (x86_64-w64-mingw32) libcurl/7.84.0 BoringSSL/c239ffd0 (Schannel) zlib/1.2.12 [...]
  Release-Date: 2022-06-27
  Protocols: dict file ftp ftps gopher gophers http https imap imaps ldap ldaps mqtt pop3 [...]
  Features: alt-svc AsynchDNS brotli gsasl HSTS HTTP2 HTTP3 HTTPS-proxy IDN IPv6 Kerberos [...]
  ```

  The setting is optional, and if not passed, BoringSSL will appear without
  a version number, like before this patch.

- makefile.m32: add support for custom ARCH [ci skip]

  When building curl for target platform other than x64 and x86, it is now
  possible to pass `ARCH=custom`, that will omit all hardcoded logic for
  setting up CFLAGS/LDFLAGS/RCFLAGS for these platforms, and let these be
  customized via `CURL_CFLAG_EXTRAS`, `CURL_LDFLAG_EXTRAS`, and a newly
  added one for the resource compiler: `CURL_RCFLAG_EXTRAS`.

  This makes it possible to use `makefile.m32` to build for ARM64 for
  example.

- cmake: do not force Windows target versions

  The goal of this patch is to avoid CMake forcing specific Windows
  versions and rely on toolchain defaults or manual selection instead.
  This gives back control to the user. This also brings CMake closer to
  how autotools and `Makefile.m32` behaves in this regard.

  - CMake had a setting `ENABLE_INET_PTON` defaulting to `ON`, which did
    nothing else than fixing the Windows build target to Vista. This also
    happened when the toolchain did not have Vista support (e.g. original
    MinGW), breaking such builds.

    In other environments it did not make a user-facing difference,
    because libcurl has its own pton() implementation, so it works well
    with or without Vista's inet_pton().

    This patch drops this setting. inet_pton() is now used whenever
    building for Vista or newer, either when requested manually or by
    default with modern toolchains (e.g. mingw-w64). Older envs will fall
    back to curl's pton().

    Ref: https://github.com/curl/curl/pull/9027#issuecomment-1164157604
    Ref: https://github.com/curl/curl/pull/8997#issuecomment-1164344155

  - When the user did no select a Windows target version manually, stop
    explicitly targeting Windows XP, and instead use the toolchain default.

    This may pose an issue with old toolchains defaulting to pre-XP
    targets. In such case you must manually target Windows XP via:
      `-DCURL_TARGET_WINDOWS_VERSION=0x0501`
    or
      `-DCMAKE_C_FLAGS=-D_WIN32_WINNT=0x0501`

- windows: improve random source

  - Use the Windows API to seed the fallback random generator.

    This ensures to always have a random seed, even when libcurl is built
    with a vtls backend lacking a random generator API, such as rustls
    (experimental), GSKit and certain mbedTLS builds, or, when libcurl is
    built without a TLS backend. We reuse the Windows-specific random
    function from the Schannel backend.

  - Implement support for `BCryptGenRandom()` [1] on Windows, as a
    replacement for the deprecated `CryptGenRandom()` [2] function.

    It is used as the secure random generator for Schannel, and also to
    provide entropy for libcurl's fallback random generator. The new
    function is supported on Vista and newer via its `bcrypt.dll`. It is
    used automatically when building for supported versions. It also works
    in UWP apps (the old function did not).

  - Clear entropy buffer before calling the Windows random generator.

    This avoids using arbitrary application memory as entropy (with
    `CryptGenRandom()`) and makes sure to return in a predictable state
    when an API call fails.

  ftp: restore protocol state after http proxy CONNECT

  connect_init() (lib/http_proxy.c) swaps out the protocol state while
  working on the proxy connection, this is then restored by
  Curl_connect_done() after the connection completes.

  ftp_do_more() extracted the protocol state pointer to a local variable
  at the start of the function then calls Curl_proxy_connect(). If the proxy
  connection completes, Curl_proxy_connect() will call Curl_connect_done()
  (via Curl_proxyCONNECT()), which restores data->req.p to point to the ftp
  protocol state instead of the http proxy protocol state, but the local
  variable in ftp_do_more still pointed to the old value.

  Ultimately this meant that the state worked on by ftp_do_more() was the
  http proxy state not the ftp state initialised by ftp_connect(), but
  subsequent calls to any ftp_ function would use the original state.

  For my use-case, the visible consequence was that ftp->downloadsize was
  never set and so downloaded data was never returned to the application.

  This commit updates the ftp protocol state pointer in ftp_do_more() after
  Curl_proxy_connect() returns, ensuring that the correct state pointer is
  used.

- rand: stop detecting /dev/urandom in cross-builds

  - Prevent CMake to auto-detect /dev/urandom when cross-building.
    Before this patch, it would detect it in a cross-build scenario on *nix
    hosts with this device present. This was a problem for example with
    Windows builds, but it could affect any target system with this device
    missing. This also syncs detection behaviour with autotools, which also
    skips it for cross-builds.
  - Also, make sure to never use the file RANDOM_FILE as entropy for libcurl's
    fallback random number generator on Windows. Windows does not have the
    concept of reading a random stream from a filename, nor any guaranteed
    non-world-writable path on disk. With this, a manual misconfiguration or
    an overeager auto-detection can no longer result in a user-controllable
    seed source.

- Makefile.m32: stop forcing XP target with ipv6 enabled [ci skip]

  Since this [1] commit in 2011, `_WIN32_WINNT` was set fixed to Windows
  XP when the `-ipv6` option is selected. Maybe this was added to support
  pre-XP Windows versions (?). These days libcurl builds fine for both XP
  and post-XP versions with IPv6 support enabled. The relevance of pre-XP
  version is also low by now. Other build methods also do not impose such
  limitation for a similar configuration. So, drop this hard-wired
  `_WIN32_WINNT` limit from `Makefile.m32`, thus building for the default
  Windows version set by the compiler. This is Vista for recent MinGW
  versions.

  Old behaviour can be restored by setting this envvar:
  export CURL_CFLAG_EXTRAS=-D_WIN32_WINNT=0x0501

- version: rename threadsafe-init to threadsafe

  Referring to Daniel's article [1], making the init function thread-safe
  was the last bit to make libcurl thread-safe as a whole. So the name of
  the feature may as well be the more concise 'threadsafe', also telling
  the story that libcurl is now fully thread-safe, not just its init
  function. Chances are high that libcurl wants to remain so in the
  future, so there is little likelihood of ever needing any other distinct
  `threadsafe-<name>` feature flags.

  For consistency we also shorten `CURL_VERSION_THREADSAFE_INIT` to
  `CURL_VERSION_THREADSAFE`, update its description and reference libcurl's
  thread safety documentation.

  RFC 7616 (and 2617) requires values to be "unquoted" before used for

  realm=DOMAN\\host are different realms).

  This commit adds unquoting (de-escaping) of all values during header
  parsing and quoting of the values during header forming. This approach
  should be most straightforward and easy to read/maintain as all values
  are processed in the same way as required by RFC.

  double-quotes themselves are escaped with backslashes, like \". It also
  supports \n, \r and \t for newline, carriage return and tabs
  respectively.

  If the password does not start with a double quote, it will end at first
  white space and no escaping is performed.

  WARNING: this change is not entirely backwards compatible. If anyone
  previously used a double-quote as the first letter of their password,
  the parser will now get it differently compared to before. This is
  highly unfortunate but hard to avoid.

- FAQ: Clarify Windows double quote usage

  - Windows command prompt doesn't use literal quoting via single quotes.

  - Windows command prompt inner double quotes are escaped with a
    backslash.

  - Windows powershell does use single quotes but curl is not a powershell
    script so the arguments may not be passed on correctly.

  - Windows powershell inner double quotes seems can be passed to curl if
    the outer quotes are double quotes and an escape of backslash-backtick
    is used.

  Command prompt example:

  ~~~
  getargs -v -d "\"a\""

  argv[0]: getargs
  argv[1]: -v
  argv[2]: -d
  argv[3]: "a"
  ~~~

  This function has been unused since the initial commit of the GSKit
  backend in 0eba02fd4.  The motivation for the code was getting the
  whole certificate chain: the only place where the latter is available
  is as a callback parameter.  Unfortunately it is not possible to pass
  a user pointer to this callback, which precludes the possibility to
  associate the cert chain with a data/conn structure.

  For further information, search for pgsk_cert_validation_callback on:
  https://www.ibm.com/docs/api/v1/content/ssw_ibm_i_71/apis/gsk_attribute_set_callback.htm

  behavior. Fix by ensuring that the FILE pointer is set before calling
  fclose on it, and issue a warning in case the file cannot be opened.
  Erroring out on nonexisting file would break backwards compatibility of
  very old behavior so we can't really go there.

  tool_paramhlp: use feof(3) to identify EOF correctly when using fread(3)

  This loop was using the number of bytes read from the file as condition
  to keep reading.

  From Linux's fread(3) man page:
  > On success, fread() and fwrite() return the number of items read or
  > written. This number equals the number of bytes transferred only when
  > size is 1. If an error occurs, or the end of the file is reached, the
  > return value is a short item count (or zero).
  >
  > The file position indicator for the stream is advanced by the number
  > of bytes successfully read or written.
  >
  > fread() does not distinguish between end-of-file and error, and
  > callers must use feof(3) and ferror(3) to determine which occurred.

  This means that nread!=0 doesn't make much sense as an end condition for
  the loop: nread==0 doesn't necessarily mean that EOF has been reached or
  an error has occured (but that is usually the case) and nread!=0 doesn't
  necessarily mean that EOF has not been reached or that no read errors
  have occured. feof(3) and ferror(3) should be uses when using fread(3).

  Currently curl has to performs an extra fread(3) call to get a return
  value equal to 0 to stop looping.

  This usually "works" (even though nread==0 shouldn't be interpreted as
  EOF) if stdin is a pipe because EOF usually marks the "real" end of the
  stream, so the extra fread(3) call will return immediately and the extra
  read syscall won't be noticeable:

      bash-5.1$ strace -e read curl -s -F file=@- 0x0.st <<< a 2>&1 |
      > tail -n 5
      read(0, "a\n", 4096)                    = 2
      read(0, "", 4096)                       = 0
      read(0, "", 4096)                       = 0
      http://0x0.st/oRs.txt
      +++ exited with 0 +++
      bash-5.1$

  But this doesn't work if curl is reading from stdin, stdin is a
  terminal, and the EOF is being emulated using a shell with ^D. Two
  consecutive ^D will be required in this case to actually make curl stop
  reading:

      bash-5.1$ curl -F file=@- 0x0.st
      a
      ^D^D
      http://0x0.st/oRs.txt
      bash-5.1$

  A possible workaround to this issue is to use a program that handles EOF
  correctly to indirectly send data to curl's stdin:

      bash-5.1$ cat - | curl -F file=@- 0x0.st
      a
      ^D
      http://0x0.st/oRs.txt
      bash-5.1$

  This patch makes curl handle EOF properly when using fread(3) in
  file2memory() so that the workaround is not necessary.

  Since curl was previously ignoring read errors caused by this fread(3),
  ferror(3) is also used in the condition of the loop: read errors and EOF
  will have the same meaning; this is done to somewhat preserve the old
  behaviour instead of making the command fail when a read error occurs.

  There is no such MSVC version (yet) as VC15 or VC17.

  For VS 2017 for example, the name we use is correct as either VS17,
  VS2017, VC14.10. I opted for the latter since we use VC for earlier

  - If building libcurl against an old libssh version missing SSH_S_IFMT

  Prior to this change if libssh did not define SSH_S_IFMT and SSH_S_IFLNK

- tool and tests: force flush of all buffers at end of program

  On Windows data can be lost in buffers in case of abnormal program
  termination, especially in process chains as seen due to flaky tests.
  Therefore flushing all buffers manually should avoid this data loss.

  In the curl tool we play the safe game by only flushing write buffers,
  but in the testsuite where we manage all buffers, we flush everything.

  This should drastically reduce Windows CI and testsuite flakiness.

  runtests: make 'oldlibssh' be before 0.9.4

  The 'oldlibssh' feature indicates that the error code returned by libssh
  for a broken known_hosts file should be 67 rather than 60 (test1459).
  This feature was added as part of #8444 with 'oldlibssh' mapping to
  libssh versions prior to 0.9.6, and then refined as part of #8511 to map
  to versions prior to 0.9.5.

  In Red Hat Enterprise Linux 8.5 there is a patched version of libssh
  version 0.9.4 (https://git.centos.org/rpms/libssh/blob/c8/f/SOURCES) in
  which test1459 fails because it returns the "new" value rather than the
  "old" one. It's plausible that one of the patches is responsible for
  this rather than the underlying code but I don't think so.

  This change therefore drops the 'oldlibssh' version check to map to
  libssh versions older than 0.9.4, which fixes builds on RHEL-8.

- openssl: check if sessionid flag is enabled before retrieving session

  Ideally, Curl_ssl_getsessionid should not be called unless sessionid

  ensure that. Therefore, the pattern in all vtls is basically:

    if(primary.sessionid) {lock(); Curl_ssl_getsessionid(...); unlock();}

  There was one instance in openssl.c where sessionid was not checked
  beforehand and this change fixes that.

  When OpenSSL 3.0 is built with `--api=3.0` and `no-deprecated`, the SRP

  mbedtls: return CURLcode result instead of a mbedtls error code

  ... when a certificate fails to be loaded from a blob

  Closes #8266

- curl_multi_socket.3: remove callback and typical usage descriptions

  1. The callback is better described in the option for setting it. Having
  it in a single place reduces the risk that one of them is wrong.

  2. The "typical usage" is wrong since the functions described in this
  man page are both deprecated so they cannot be used in any "typical" way
  anymore.

  Closes #8262

- curl-functions.m4: revert DYLD_LIBRARY_PATH tricks in CURL_RUN_IFELSE

  Mostly reverts ba0657c343f, but now instead just run the plain macro on
  darwin. The approach as used on other platforms is simply not necessary
  on macOS.

  openldap: implement SASL authentication

  As credentials can be quite different depending on the mechanism used,
  there are no default mechanisms for LDAP and simple bind with a DN is
  then used.

  The caller has to provide mechanism(s) using CURLOPT_LOGIN_OPTIONS to
  enable SASL authentication and disable simple bind.

  CURLOPT_RESOLVE.3: change example port to 443

  CURLOPT_RESOLVE being set to port 80 in the documentation means that it

- mesalink: remove support

  Mesalink has ceased development. We can no longer encourage use of it.

- ldap: return CURLE_URL_MALFORMAT for bad URL

  For consistency, use the same return code for URL malformats,

  rustls: add CURLOPT_CAINFO_BLOB support

  Add support for `CURLOPT_CAINFO_BLOB` `CURLOPT_PROXY_CAINFO_BLOB` to the
  rustls TLS backend. Multiple certificates in a single PEM string are
  supported just like OpenSSL does with this option.

  This is compatible at least with rustls-ffi 0.8+ which is our new
  minimum version anyway.

  I was able to build and run this on Windows, pulling trusted certs from
  the system and then add them to rustls by setting
  `CURLOPT_CAINFO_BLOB`. Handy!

  mbedtls: fix private member designations for v3.1.0

  "As a last resort, you can access the field foo of a structure bar by
  writing bar.MBEDTLS_PRIVATE(foo). Note that you do so at your own risk,
  since such code is likely to break in a future minor version of Mbed
  TLS." -

  That future minor version is v3.1.0. I set the >= to == for the version
  checks because v3.1.0 is a release, and I am not sure when the private
  designation was reverted after v3.0.0.

  Make ngtcp2+quictls correctly acknowledge `CURLOPT_SSL_VERIFYPEER` and

  able to use for both regular TLS and QUIC.
