sasl: fix zero-length response encoding
A sasl zero-length normal response is an empty string, unlike an initial
response. Since the encoding of a zero-length initial response is
protocol dependent, move its handling to the protocol-specific sendauth
procedure. Similarly, do not check for an '=' server message, as this
should normally never occur.

Update the erroneous tests accordingly.

tests: pin connection reuse rules for partial, host, and credentials
Add classic tests 3223-3226 and extend tests/http/test_12_reuse.py so that
connection reuse decisions are explicit:

- partial/aborted HTTP/1.1 responses must not reuse the connection
  (premature multi_done closes non-multiplexed conns)
- different target hostnames must not share a connection even when they
  resolve to the same address (url_match_destination)
- HTTP Basic credentials are per-request (PROTOPT_CREDSPERREQUEST), so
  different -u values still reuse; assert that with num_connects
- same host positive control reuses (num_connects 1 then 0)

openssl+sectrust: fix session reuse
When TLS is verified via Apple SecTrust, openssl internal state is a
verification faiure (that is how it works, we use sectrust when openssl
fails to verify and natice ca store is enabled).

OpenSSL stores this verification status inside its TLS session objects.
On reuse, we see an unverified session and do not reuse it for a
verified connect attempt. While this is a performance penalty for most
connections, it *fails* on ftps:// transfers where servers expect
session reuse on DATA connections.

Fix this by remembering that TLS and a session was verified by sectrust
and allow reuse of such sessions for new connect attempts that also use
sectrust.

vssh: keyfile use cleanups
- make the libssh backend do the same fallback for private and public key
  filename as libssh2 already did and is documented behavior. This now uses a
  common function.

- set the file names already in setup_connection if public key auth is
  requested, so that the connection reuse functions can use the
  information when checking for existing connections to reuse

- rename the oddly named struct fields 'rsa' to 'priv_key' and 'rsa_pub'
  to 'pub_key' to better reflect their purposes

FTP: fix TLS session reuse on the data connection
FTP servers using SSL can be configured to check TLS session reuse on
the DATA connection. They hand out a new session on every CONTROL
connect and require to see the client using exactly that one when
up-/downloading on DATA.

This means:

1. We have to configure the SSL filter on the DATA connection with
   exactly the same peers.

2. We have to remember the SSL session on the CONTROL connection -
   separately from the session cache. The SSL filter on the DATA
   connection then looks for a session at the CONTROL filter and, if
   present, uses that.

Tests:

Enable `require_ssl_reuse` in our pytest setup for vsftpd. This
reproduces the problem reported in #22225 and verifies the fix.

Skip ftp+SSL pytests for rustls, as we have no possibility to reuse
sessions in that backend.

Schannel: we do not run these tests with the backend. I expect it has
similar problems but am not able to verify.

configure: link `-lcrypt32` instead of `-lm` for wolfSSL on Windows
Syncing it with CMake/FindWolfSSL.

`-lm` is not needed on Windows. As of mingw-w64 14.0.0 it's offered as
a dummy library; in such case it wasn't causing an actual issue.
`-lcryp32` is necessary when linking wolfSSL statically.

cd2nroff: stricter checks for asterisks for italics
The nroff (man page) version of the markdown docs could get asterisks
mistreated as emphasis - seen in the CURLOPT_WRITEDATA manpage. The
regex now more stricter requires a word character to follow an italics
starting asterisk and there needs to be a word character or a closing
parenthesis before the italics ending asterisk.

Also: fix CURLINFO_CERTINFO.md which used wrong italics - it was not
rendered correctly on GitHub and with other generic markdown parsers.

gssapi: add support for Apple GSS Framework
Add support for the native GSS Framework on Apple targets, which is
Apple's fork of Heimdal. This option allows to drop Apple's deprecated
MIT Kerberos compatibility shim "mit-krb5/1.7-prerelease".

Source code uses different headers, other than that no source changes
are necessary.

You can enable by configuring with:
autotools: `--enable-gssapi-apple`
CMake: `-DCURL_USE_GSSAPI=ON -DCURL_GSS_FLAVOR=Apple`

These options are experimental, and may receive breaking updates till
the GSS backend selection logic settles, for Apple and also for the GNU
and MIT implementation.

Version string:
```
curl 8.21.0-DEV (aarch64-apple-darwin25.4.0) libcurl/8.21.0-DEV
  OpenSSL/3.6.2 zlib/1.2.12 AppleIDN AppleGSS OpenLDAP/2.4.28/Apple
```

Also:
- drop in-source deprecation warning suppressions when using AppleGSS.
- GHA/macos: enable Apple GSS in CI jobs.

Supported by:
iOS 5.0+, iPadOS 5.0+, Mac Catalyst 13.0+, macOS 10.14+, visionOS 1.0+

test2114: fix reading from stdin
The test provides an invalid username, but no ':' with password, so that
the curl tool tries to read the password from stdin. That makes the test
hang, also in CI.

The check for invalid characters is happening when the CURLOPT_USERPWD
is applied to the URL, so when the transfer is started. Maybe the check
should happen also in setopt already.

The test hangs because tool_paramhlp.c:548 `checkpasswd()` does not see
a ':' and tries to read the password from stdin.

Fix: add a ':' in the tests invalid user setting, so that the read does
not happen.

tool: fix memory use in parallel mode
The curl tool was creating a new transfer every time it checked if
it needed to add one to reach max parallelism. This led to eventually
all configured transfers to have easy handles created.

Limit the creation again to the ones needed for max parallelism.

Test 1701 did a HTTP/2 Upgrade in a HTTP/1.1 POST request. This will no
longer be supported in the upcoming nghttp2 release for security reasons
(Upgrade requests with body a re messy, error prone and can easily lead
to connection confusion).

As no other server we have supports this, remove the test.

ws: pause/unpause write handling
Websocket frames need to be written individualy, so that applications
can access the frame meta data correctly. This worked until the write
function triggered a pause. Remaining frames accumulated in the "out"
writer's buffer and on unpaused were written in one chunk.

ws decode writer will now stop writing frames when the client writer
is paused. To handle the writing of buffered raw data after an unpause,
client writers have gotten a new "flush" method.

Add pytest test_20_12 with a new client to check handling of pauses
and websocket frames.

conncache: apply multi limits to transfers using a shared pool
- Determine max host and total connection limits from the transfer's own
  multi handle and test that it works for shared connections.

Prior to this change, since df67269 (precedes 8.13.0),
Curl_cpool_check_limits() took the limits from the multi handle that
owns the pool. A share-owned pool is not owned by any multi, so the
limit check always passed.

Prior to df67269 the limits came from the transfer's own multi handle.

`GNUTLS_ENABLED` was checked twice in the HTTPS-proxy support block,
making the second check redundant.

idn: restore `MultiByteToWideChar()` `MB_ERR_INVALID_CHARS` flag
Also:
- curlx: pass this flag to the actual conversion calls, for consistency
  and robustness. (It's not stricly necessary because the initial call
  to determine size, with this flag passed, fails already on bad input.)

tidy-up: `TEXT()` vs `_TEXT()` vs `_T()` use (Windows)
Use `_TEXT()` when interacting with CRT functions (also prefer over
synonym `_T()`), `TEXT()` for Win32 functions.

Within curl, they mean the same because CRT/Win32 Unicode mode are
always enabled in sync.

quiche: set the max field section size
quiche 0.29.3 started enforcing a default
`SETTINGS_MAX_FIELD_SECTION_SIZE` of 32 KiB, so larger response headers
now shut down the whole connection with `CURLE_HTTP3`. curl accepts up
to 300 KiB of response headers with every other backend and HTTP
version. Tell quiche to allow what curl itself allows. This keeps
test_01_11 passing with quiche 0.29.3 and it also advertises our real
limit to servers, which the RFC encourages.

ngtcp2: let verify failures win over expiry processing errors
A flaky CI failure of `test_17_05_bad_ip_addr[h3]` (GnuTLS, event-based)
had curl detect the certificate name mismatch yet exit with
`CURLE_RECV_ERROR` (56) instead of `CURLE_PEER_FAILED_VERIFICATION`
(60). `Curl_cf_ngtcp2_cmn_connect` calls `Curl_cf_ngtcp2_cmn_set_expiry`
after its `ctx->tls_vrfy_result` override and returns the error
unfiltered, so when the server's final handshake flight happens to be
processed by the ingress inside set_expiry, the verify failure surfaces
as a generic receive error.

This PR makes set_expiry prefer `ctx->tls_vrfy_result` over generic
progress errors, as the recv and send paths already do after calling it,
and also covers the `cf-ngtcp2-proxy.c` call sites that lack the
override. Completes #21712. Seen in
https://github.com/curl/curl/actions/runs/29243256619/job/86794119412.

test798: force IPv4 to avoid cross-runner port aliasing
`test798` is the only test fetching `http://localhost:%HTTPPORT` without
`-4`, since it needs the hostname for its folded `domain=localhost`
cookie. curl tries `::1` first, but the test HTTP server is IPv4-only.
On the BSDs, IPv4 and IPv6 have separate ephemeral port namespaces, so
with every test server binding port 0, another parallel runner's
IPv6-bound server can hold the same numeric port. curl then connects to
the wrong runner's server, which cannot open its own `log/N/test798` and
closes without a response, giving exit 52 and an empty `server.input`.

This PR fixes this flake by adding `-4` matches what tests 389 and 392
already do. Linux is immune because wildcard IPv6 binds occupy the IPv4
port too. Seen in
https://github.com/curl/curl/actions/runs/29229170329/job/86749470571.

cfilters: fix event-based connection shutdown
- Adjust pollset during connection shutdown.

- Separate the FIRSTSOCKET and SECONDSOCKET check so that one being in
  connect or shutdown no longer adds poll events for the other.

- Fix shutdown state evaluation (as detailed below).

- Add a unit test for Curl_conn_adjust_pollset.

- Add a client for event testing.

- Test that shutdown sockets stay with the socket callback until done.

The pollset predicate now reads the connection's own shutdown state
rather than going through data->conn, and the EXPIRE_SHUTDOWN arming in
cshutdn_perform() works again: next_expire_ms started at 0 and could
never be set, so a peer that never sends a close_notify would still park
its connection forever, timeout or not.

tests: fix type promotion on 32-bit arches in http test code
As reported in the bug:

> On a 32-bit architecture (i386):
> 1. `chunks * chunk_size` evaluates to `unsigned int` (32-bit
>    unsigned).
> 2. Due to Usual Arithmetic Conversions in C, the signed `-1` (int)
>    operand of the ternary operator is promoted to `unsigned int`,
>    yielding `4294967295` (0xFFFFFFFF).
> 3. The ternary operator returns `4294967295` as an `unsigned int`.
> 4. This unsigned value is then assigned to `r->clength` (apr_off_t,
>    64-bit signed). Since the source is unsigned, it is zero-extended,
>    resulting in `r->clength` becoming `+4294967295`.
> 5. The subsequently executed check `if(r->clength >= 0)` evaluates to
>    true.
> 6. Inside the block, `apr_ltoa(r->pool, (long)r->clength)` casts it to
>    a 32-bit signed `long` (on 32-bit platforms), which truncates it
>    back to `-1`, formatting it as "-1" and sending the
>    "Content-Length: -1" header.
>
> On a 64-bit architecture (amd64), `size_t` is 64-bit, and `-1` (32-bit
> int) is promoted to `unsigned long` (64-bit), yielding
> `18446744073709551615`. When assigned to `r->clength` (64-bit signed),
> it wraps back to `-1`, which correctly skips the Content-Length
> generation.

> This type promotion mismatch can be safely fixed by avoiding the

I've tested the fix using [debusine on i386 runner](https://debusine.debian.net/debian/developers/artifact/4083252/raw/log):

> 782s tests/http/test_05_errors.py::TestErrors::test_05_04_unclean_tls_shutdown[http/1.0] PASSED [ 17%]
> 782s tests/http/test_05_errors.py::TestErrors::test_05_04_unclean_tls_shutdown[http/1.1] PASSED [ 18%]
> 782s tests/http/test_05_errors.py::TestErrors::test_05_04_unclean_tls_shutdown[h2] PASSED [ 18%]

Versus the [i386 run in Debian's infrastructure](https://debusine.debian.net/debian/developers/artifact/4084220/raw/log):

> 2690s tests/http/test_05_errors.py::TestErrors::test_05_04_unclean_tls_shutdown[http/1.0] FAILED [ 17%]
> 2690s tests/http/test_05_errors.py::TestErrors::test_05_04_unclean_tls_shutdown[http/1.1] PASSED [ 18%]
> 2690s tests/http/test_05_errors.py::TestErrors::test_05_04_unclean_tls_shutdown[h2] PASSED [ 18%]

lib: add multi_wakeup_internal
For threaded resolving, added an additional socket/eventfd pair to the
multi handle for notifications from threads. The original "double use"
of the standard wakeup pair did lead to regressions for apps.

The API definition of curl_multi_poll/wait/wakeup is pretty tight
regarding what effects what and adding notifications on top of that
broke what apps perceived to be the contract.

cf-dns: resolve on filter demand
Use separate dns cache entries for addresses (A+AAAA) and HTTPS-RR
results. That makes also "negative" results independent of each other.
Dns cache entries, once in use, can no longer be modified safely, as
concurrent use would require each access then to be done under lock. By
using separate entries, we can update a HTTPS entry without needing to
duplicate an existing address entry for the same host+port.

Connection filters can now ask for DNS resolves. This works at any time
during connection setup and while connect is going on.
`Curl_conn_dns_add_addr_resolve()` and
`Curl_conn_dns_add_https_resolve()` are used for that. They check if the
resolve is already ongoing, can be added to a resolve not started yet
or, as last resort, create a new filter instance and add it to the
connection (it's easier to add more filters than making the same filter
handle multiple resolves. Since DNS filters are removed once the
connection is established, there is no later penalty).

HTTPS-RR queries are added by the `HTTPS-CONNECT`, `SSL` and `QUIC`
filters. The latter will only do that when ECH is configured and
supported. That means we trigger HTTPS-RR queries only when the results
matter.

Add test_22_06 for ALPN influenced via HTTPS-RR when tunneling through a
proxy. This did not work before.

Adjust test2100 to use https: as the previous http: URL no longer
triggers HTTPS-RR resolves.

hardening: add API guards
Add call stacks to easy and multi instances. Record ongoing API calls
and callback invocations there to detect recursion and not allowed
invocations.

Define enums for easy, multi and callbacks in `api.h`. In `api.c` define
properties for these functions:

- can they recurse
- is the easy/multi handle destroyed during the call or should it be
  good afterwards
- is the call allowed when a multi event callback is ongoing
- is the call allowed when a notification callback is ongoing

Entering a guard
- checks that passed CURL*/CURLM* are GOOD on entering
- checks that easy handle's `mid` is correct and it is known
  for it in the multi.
- checks that call properties are obeyed (recursion, callback checks)
- checks that passed CURL*/CURLM* are GOOD on leaving, unless call is
  known to kill it

Checks for ongoing callbacks inspect the whole call stack and catches
nested invocations (which our current flags can not).

Call stacks in easy/multi handle are fixed size and will deny recursion
when the limit is reached. The current limits are 7 for easy and 15 for
multi now.

Removes:
- multi->in_callback, check is done via call stack
- multi->in_ntfy_cb, check is done via call stack

The overhead in my tests seems minimal, if noticeable at all.

tool_xattr: add support for Windows alternate data stream
Requires a supported filesystem, i.e. NTFS.

Example:
```console
> curl.exe https://curl.se/index.html --output test.txt --xattr --referer https://curl.se/
> cat < test.txt:Zone.Identifier

[ZoneTransfer]
HostUrl=https://curl.se/index.html
ReferrerUrl=https://curl.se/
```

Where newlines are CLRF, `ReferrerUrl` is set when using `--referer`
option.

Also:
- test688: make it test `--referer`.
- document `user.xdg.referrer.url` in `--xattr` man page.

configure: only check in the watt library if WATT_ROOT is set
Only look for gethostbyname in libwatt in $WATT_ROOT/lib if WATT_ROOT
has actually been set. This avoids configure trying to search in /lib,
which won't every succeed and can cause problems in cross builds which
check that host paths are not being searched.

asyn-thrdd: retry link-local ipv6 if missing scope id
When the threaded resolver gets AAAA results that carry a link-local
address without scope-id, it now re-queues a query with AF_UNSPEC and
strips ipv4 addresses from that result. Whatever the resulting addresses
and scope-ids are, this becomes the result of the resolve.

tidy-up: drop redundant includes
`sys/types.h` and `sys/socket.h` (non-Win32). They are included via
`curl/curl.h` and `curl_setup.h`.

This drops `HAVE_SYS_TYPES_H` guards from the codebase. It's safe
because `sys/types.h` (POSIX) is already required unconditionally by
`curl/curl.h`. It remains used in feature checks by both autotools and
cmake; to be reviewed in a future step.

httpsig: add RFC 9421 HTTP Message Signatures support
Add support for signing outgoing HTTP requests per RFC 9421 using
Ed25519 or HMAC-SHA256 algorithms.

New libcurl options:
 - CURLOPT_HTTPSIG: signing algorithm ("ed25519" or "hmac-sha256")
 - CURLOPT_HTTPSIG_KEY: path to hex-encoded key file
 - CURLOPT_HTTPSIG_KEYID: key identifier for Signature-Input
 - CURLOPT_HTTPSIG_HEADERS: space-separated components to sign

New CLI flags: --httpsig, --httpsig-key, --httpsig-keyid,
--httpsig-headers

The crypto layer follows the sha256.c multi-backend pattern with
implementations for OpenSSL (EVP_DigestSign) and wolfSSL
(wc_ed25519_sign_msg). HMAC-SHA256 uses the existing Curl_hmacit()
infrastructure which works on all backends.

Verified by test 5000 to 5021

runtests: fix `mode="warn"` tests passing unconditionally, fix test 1752
Fix test 1712 to pass curl C by setting `COLUMNS` to the highest
accepted value, and adjust expected results. To avoid envs with varying
lengths of `LOGDIR` affect the outcome.

Apply the same fix to test 459, though it wasn't affected in curl CI.

Also sync up test 433 `COLUMNS` value with these two tests for
consistency.

vquic: silence `-Wmissing-field-initializers` for nghttp3/ngtcp2 callback tables
To avoid a breakage in CI and curl-for-win builds on upstream updates
extending the callback lists. Each such breakage needed patching curl,
rolling these patches into curl-for-win, and doing it in near real-time,
to keep CI and builds working (and still causing some red CI jobs).

Bring calmness here by suppressing the warnings and allowing time to
extend the callback tables as/if needed and at a convenient moment.

spnego: block NTLM fallback in SPNEGO negotiation
- Switch the Windows SSPI identity struct to SEC_WINNT_AUTH_IDENTITY_EX
  to use !ntlm in PackageList to prevent NTLM from being offered.

- For GSS filter out NTLMSSP OID, and restrict via gss_set_neg_mechs()
  to prevent NTLM from being offered.

- Extend the GSS-API debug stub layer to support the NTLM blocking logic
  without a real Kerberos environment.

- Update test 2057 to check that negotiate auth is silently skipped with
  no Authorization header when only NTLM stub credentials are available.

- Add SPNEGO NTLM blocking test 2093 which verifies that Kerberos
  credentials still succeed when NTLM is blocked within SPNEGO.

- Suppress tests valgrind leak for MIT krb5 gss_display_status, since
  the leak is in the library and not in curl.

To suppress the tests valgrind leak, the wildcard '...' bridges over an
anonymous frame inside libgssapi_krb5.so that valgrind reports as '???'.

urlapi: improved return codes
- add CURLUE_BACKSLASH that can be returned when a backslash was used
  where a forward one probably was intended.

- make CURLUE_NO_HOST higher priority than port number errors for URLs
  without hostname. Like in "http://::1"

- shortened some URL parser error strings

Extend test 1560 to verify.

tidy-up: use more `static`, `sizeof()`, `char[]`, double-const
- make `const` data `static`, where missing and possible.
- replace `strlen()` on literal or const strings with `sizeof()`.
  While the latter is optimized by popular C compiler, e.g. MSVC only
  does it with `/O2`.
- replace magic numbers with `sizeof()`, where missing.
- introduce `CURL_CSTRLEN()` macro for `sizeof(char[]) - 1`.
- use `CURL_CSTRLEN()` macro.
- move `const` before integer types, where missing.
- replace `char *var` with `var[]`, where missing and possible.
- use double const, where missing.
  `static const char *` -> `static const char * const`.
- lib1514: constify pointers.
- unit3205: drop redundant cast, avoid another one.
- unit1666: map `OID()` macro to identical `STRCONST()`.

tests: address mutable class vars and naive datetime in Python code
Mark Python mutable class variables with ClassVar, to denote that the
danger this can cause has been considered.  Since any change made to
these in any object affects all other objects, this can cause locality
errors. However, as used in the test suite, they are are never modified
and so they are annotated as being intended.

Always set a timezone in datetime objects, as mixing naive and
timezone-aware object can cause errors.

These fix ruff rules DTZ005, RUF012.

tests: target Python 3.8 as the minimum Python version
This version is already two releases out of support, but is "only" 7
years old so is probably still being used in the real world. Document
this version along with some other testing dependencies.  Remove code
support for earlier versions. Disable ruff checks that need a newer
version.

dnsd: fix bounds check in `read_https_alpn_part()`
"The check `i > 256` permits `i == 256` to pass through. When `i` is
then cast to `uint8_t` in `blob_add(b, (uint8_t)i)`, the value wraps to
0, silently encoding a zero-length ALPN entry instead of rejecting it.
The condition should be `i > 255` (or equivalently `i >= 256`) to
correctly reject any length that does not fit in a single byte."

scorecard: fix `max_upload` init value in `ul_parallel()`
"In `ul_parallel`, `max_parallel` is computed using
`self._download_parallel` instead of `self._upload_parallel`. This
causes the upload parallelism to incorrectly follow the download
parallel setting. It should use `self._upload_parallel` to be consistent
with how `uploads()` computes `max_parallel`."

vquic: add option to use Apple fast UDP
Using Apple's secret `SYS_recvmsg_x` and `SYS_sendmsg_x` syscalls for
receiving/sending batches of UDP packets.

Since it uses undocumented calls, it's experimental and disabled by
default.

To enable:
- autotools: `--enable-apple-fast-udp`
- cmake: `-DCURL_ENABLE_APPLE_FAST_UDP=ON`

Also:
- enable in two H3 CI jobs with both build tools, pytest and clang-tidy.
