The existing code tried but did not properly reject alternative services
using negative or too large port numbers.
With this fix, the logic now also flushes the old entries immediately
before adding a new one, making a following header with an illegal entry
not flush the already stored entry.
Report from the ongoing source code audit by Trail of Bits.
Adjusted test 356 to verify.

This header is for providing the argument types for recv() and send()
when built to not use a dedicated config-[platfor].h file.
Remove the slow brute-force checks from configure and cmake.
This change also removes the use of the types for select, as they were
not used in code.
Closes#9592
This function is currently located in the lib/http.c module and is
therefore disabled by the CURL_DISABLE_HTTP conditional token.
As it may be called by TLS backends, disabling HTTP results in an
undefined reference error at link time.
Move this function to vauth/vauth.c to always provide it and rename it
as Curl_auth_allowed_to_host() to respect the vauth module naming
convention.
Closes#9600
Curl_ossl_certchain() is now an exported function in lib/vtls/openssl.c that
can also be used from quiche.c and ngtcp2.c to get the cert chain for QUIC
connections as well.
The *certchain function was moved to the top of the file for this reason.

According to `docs/INTERNALS.md`, internal function names spanning source
files start with uppercase `Curl_`. Bring these two functions in
alignment with this.
This also stops exporting them from `libcurl.dll` in autotools builds.

This is the single place in libcurl code where it uses the "native"
s(n)printf() function. Used for writing floats. The use has been
reviewed and vetted and uses a HUGE target buffer, but switching to
snprintf() still makes this safer and removes build-time warnings.

Replace bit mask protocol sets by null-terminated arrays of protocol
tokens. These are the addresses of the protocol names returned by
curl_version_info().
Protocol names are sorted case-insensitively before output to satisfy CI
tests matches consistency.
The protocol list returned by curl_version_info() is augmented with all
RTMP protocol variants.
Test 1401 adjusted for new alpha ordered output.

The check may take many milliseconds, so now it is performed once the

The "Failed to connect to" message after a connection failure would
include the strerror message based on the presumed previous socket
error, but in times it seems that error number is not set when reaching
this code and therefore it would include the wrong error message.
The strerror message is now removed from here and the curl_easy_strerror
error is used instead.

After this update autotools builds will compile and link `.rc` resources
to Windows executables. Bringing this feature on par with CMake and
Makefile.m32 builds. And also making it unnecessary to improvise these
steps manually, while monkey patching build files, e.g. [0].
You can customize the resource compiler via the `RC` envvar, and its
options via `RCFLAGS`.
This harmless warning may appear throughout the build, even though the
autotools manual documents [1] `RC` as a valid tag, and it fails when
omitting one:
`libtool: error: ignoring unknown tag RC`

This also returns error CURLE_UNSUPPORTED_PROTOCOL rather than
CURLE_BAD_FUNCTION_ARGUMENT when a listed protocol name is not found.

Tests adapted accordingly.

When the parser is not allowed to guess scheme, it should consider the
word ending at the first colon to be the scheme, independently of number
of slashes.
The parser now checks that the scheme is known before it counts slashes,
to improve the error messge for URLs with unknown schemes and maybe no
slashes.
When following redirects, no scheme guessing is allowed and therefore
this change effectively prevents redirects to unknown schemes such as
"data".
Fixes#9503
This internal-use-only storage type can be bumped to a curl_off_t once
we need to use bit 32 as the previous 'unsigned int' can no longer hold
them all then.
The websocket protocols take bit 30 and 31 so they are the last ones
that fit within 32 bits - but cannot properly be exported through APIs
since those use *signed* 32 bit types (long) in places.

Prior to this commit, non-persistent pointers were being used to store
sessions. When a WOLFSSL object was then freed, that freed the session
it owned, and thus invalidated the pointer held in curl's cache. This
commit makes it so we get a persistent (deep copied) session pointer
that we then add to the cache. Accordingly, wolfssl_session_free, which
was previously a no-op, now needs to actually call SSL_SESSION_free.
This bug was discovered by a wolfSSL customer.

The variable-sized encoding-specific storage of a struct contenc_writer
currently relies on void * alignment that may be insufficient with
regards to the specific storage fields, although having not caused any
problems yet.
In addition, gcc 11.3 issues a warning on access to fields of partially
allocated structures that can occur when the specific storage size is 0:
content_encoding.c: In function ‘Curl_build_unencoding_stack’:
content_encoding.c:980:21: warning: array subscript ‘struct contenc_writer[0]’ is partly outside array bounds of ‘unsigned char[16]’ [-Warray-bounds]
980 | writer->handler = handler;
| ~~~~~~~~~~~~~~~~^~~~~~~~~
In file included from content_encoding.c:49:
memdebug.h:115:29: note: referencing an object of size 16 allocated by ‘curl_dbg_calloc’
115 | #define calloc(nbelem,size) curl_dbg_calloc(nbelem, size, __LINE__, __FILE__)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
content_encoding.c:977:60: note: in expansion of macro ‘calloc’
977 | struct contenc_writer *writer = (struct contenc_writer *)calloc(1, sz);
To solve both these problems, the current commit replaces the
contenc_writer/params structure pairs by "subclasses" of struct
contenc_writer. These are structures that contain a contenc_writer at
offset 0. Proper field alignment is therefore handled by the compiler and
full structure allocation is performed, silencing the warnings.
