Closes: #8786 Reviewed-by: Daniel Stenberg - RELEASE-NOTES: synced - gskit: remove unused function set_callback 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 As the upstream library never added a parameter like that to the API, we give up the wait and remove the dead code.

Closes: #8692 Reviewed-by: Daniel Stenberg Reviewed-by: Nick Zitzmann - cookies: Improve errorhandling for reading cookiefile The existing programming had some issues with errorhandling for reading the cookie file. If the file failed to open, we would silently ignore it and continue as if there was no file (or stdin) passed. In this case, we would also call fclose() on the NULL FILE pointer, which is undefined 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.

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. Closes #8701 - gen.pl: change wording for mutexed options Instead of saying "This option overrides NNN", now say "This option is mutually exclusive to NNN" in the generated man page ouput, as the option does not in all cases actually override the others but they are always mutually exclusive.

Visual Studio 2022 (Visual Studio version 17 which uses MSVC 14.30) project files were recently added and followed that same format using VC17. 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 versions (eg VC10, VC12, etc).

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.

Instead the function pointers now point to the wrappers which call the MD5 functions.

Fixes #8279 Reported-by: Satadru Pramanik Closes #8280 - mqtt: free any leftover when done Oss-fuzz found an issue when the "sendleftovers" pointer could leak memory. Fix this by always freeing it (if still assigned) in the done function. Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=43515 Closes #8274 - formdata: avoid size_t => long typecast overflows Typically a problem for platforms with 32 bit long and 64 bit size_t Reported-by: Fabian Yamaguchi Bug: https://hackerone.com/reports/1444539 Closes #8272 - RELEASE-NOTES: synced bump next release to become 7.82.0 Marcel Raad (13 Jan 2022) - build: enable -Warith-conversion This makes the behavior consistent between GCC 10 and earlier versions. Closes https://github.com/curl/curl/pull/8271 - build: fix -Wenum-conversion handling Don't enable that warning when warnings are disabled. Also add it to CMake. Closes https://github.com/curl/curl/pull/8271 - appveyor: use VS 2017 image for the autotools builds The newer images don't have all required MSYS2 packages. Fixes https://github.com/curl/curl/issues/8248 Closes https://github.com/curl/curl/pull/8265 - appveyor: update images from VS 2019 to 2022 Closes https://github.com/curl/curl/pull/8265 Daniel Stenberg (12 Jan 2022) - [Michał Antoniak brought this change] 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. Fixes #8229 Reported-by: Ryan Schmidt Closes #8247 - [Patrick Monnerat brought this change] 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. Closes #8152 Jay Satiro (10 Jan 2022) - [Cameron Will brought this change] CURLOPT_RESOLVE.3: change example port to 443 83cc966 changed documentation from using http to https. However, CURLOPT_RESOLVE being set to port 80 in the documentation means that it isn't valid for the new URL. Update to 443. Closes https://github.com/curl/curl/pull/8258 Daniel Stenberg (10 Jan 2022) - [Fabian Keil brought this change] test374: gif data without new line at the end Closes #8239 - [Fabian Keil brought this change] runtests.pl: support the nonewline attribute for the data part Added to FILEFORMAT Closes #8239 - [Patrick Monnerat brought this change] curl tool: erase some more sensitive command line arguments As the ps command may reveal sensitive command line info, obfuscate options --tlsuser, --tlspasswd, --proxy-tlsuser, --proxy-tlspassword and --oauth2-bearer arguments. Reported-by: Stephen Boost Closes #7964 - mesalink: remove support Mesalink has ceased development. We can no longer encourage use of it. It seems to be continued under the name TabbySSL, but no attempts have (yet) been to make curl support it. Fixes #8188 Closes #8191 - ldap: return CURLE_URL_MALFORMAT for bad URL For consistency, use the same return code for URL malformats, independently of what scheme that is used. Previously this would return CURLE_LDAP_INVALID_URL, but starting now that error cannot be returned. Closes #8170 - docs/cmdline-opts: add "mutexed" options for more http versions Update four http version man page sections. Closes #8254 - [Stephen M. Coakley brought this change] 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!

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. Closes #8214 - [Valentin Richter brought this change] cmake: prevent dev warning due to mismatched arg -- curl version=[7.81.0-DEV] CMake Warning (dev) at /usr/share/cmake-3.22.1/Modules/FindPackageHandleStandardArgs.cmake:438 (message): The package name passed to `find_package_handle_standard_args` (MBEDTLS) does not match the name of the calling package (MbedTLS).

The name check now uses a function from lib/vtls/openssl.c which will need attention for when TLS is not done by OpenSSL or is disabled while QUIC is enabled. Possibly the servercert() function in openssl.c should be adjusted to be able to use for both regular TLS and QUIC.

Last resort is then getpwuid() if available. Previously it would first try to find a home directory and if that was set, insist on checking only that directory for the file. This now returns the full file name it finds. The Windows specific checks are now done differently too and in this order: 1 - %USERPROFILE% 2 - %APPDATA% 3 - %USERPROFILE%\\Application Data The windows order is modified to match how the Windows 10 ssh tool works when it searches for .ssh/known_hosts.

- urlapi: provide more detailed return codes
  
  Previously, the return code CURLUE_MALFORMED_INPUT was used for almost
  30 different URL format violations. This made it hard for users to
  understand why a particular URL was not acceptable. Since the API cannot
  point out a specific position within the URL for the problem, this now
  instead introduces a number of additional and more fine-grained error
  codes to allow the API to return more exactly in what "part" or section
  of the URL a problem was detected.
  
  Also bug-fixes curl_url_get() with CURLUPART_ZONEID, which previously
  returned CURLUE_OK even if no zoneid existed.
  
  Test cases in 1560 have been adjusted and extended. Tests 1538 and 1559
  have been updated.
  
  Updated libcurl-errors.3 and curl_url_strerror() accordingly.

  rustls: read of zero bytes might be okay
  
  When we're reading out plaintext from rustls' internal buffers, we might
  get a read of zero bytes (meaning a clean TCP close, including
  close_notify). However, we shouldn't return immediately when that
  happens, since we may have already copied out some plaintext bytes.
  Break out of the loop when we get a read of zero bytes, and figure out
  which path we're dealing with.

  rustls: remove incorrect EOF check
  
  The update to rustls-ffi 0.8.0 changed handling of EOF and close_notify.
  From the CHANGELOG:
  
  > Handling of unclean close and the close_notify TLS alert. Mirroring
  > upstream changes, a rustls_connection now tracks TCP closed state like
  > so: rustls_connection_read_tls considers a 0-length read from its
  > callback to mean "TCP stream was closed by peer."  If that happens
  > before the peer sent close_notify, rustls_connection_read will return
  > RUSTLS_RESULT_UNEXPECTED_EOF once the available plaintext bytes are
  > exhausted. This is useful to protect against truncation attacks. Note:
  > some TLS implementations don't send close_notify. If you are already
  > getting length information from your protocol (e.g. Content-Length in
  > HTTP) you may choose to ignore UNEXPECTED_EOF so long as the number of
  > plaintext bytes was as expected.
  
  That means we don't need to check for unclean EOF in `cr_recv()`,
  because `process_new_packets()` will give us an error if appropriate.

  configure: don't enable TLS when --without-* flags are used
  
  Previously specifying `--without-gnutls` would unexpectedly attempt to
  compile with GnuTLS, effectively interpreting this as
  `--with-gnutls`. This caused a significant amount of confusion when
  `libcurl` was built with SSL disabled since GnuTLS wasn't present.
  
  68d89f24 dropped the `--without-*` options from the configure help, but
  `AC_ARG_WITH` still defines these flags automatically. As
  https://www.gnu.org/software/autoconf/manual/autoconf-2.60/html_node/External-Software.html
  describes, the `action-if-given` is called when the user specifies
  `--with-*` or `--without-*` options.
  
  To prevent this confusion, we make the `--without` flag do the right
  thing by ignoring the value if it set to "no".

  sendf: accept zero-length data in Curl_client_write()
  
  Historically, Curl_client_write() used a length value of 0 as a marker
  for a null-terminated data string. This feature has been removed in
  commit f4b85d2. To detect leftover uses of the feature, a DEBUGASSERT
  statement rejecting a length with value 0 was introduced, effectively
  precluding use of this function with zero-length data.
  
  The current commit removes the DEBUGASSERT and makes the function to
  return immediately if length is 0.
  
  A direct effect is to fix trying to output a zero-length distinguished
  name in openldap.
  
  Another DEBUGASSERT statement is also rephrased for better readability.

- Makefile.m32: fix to not require OpenSSL with -libssh2 or -rtmp options
  
  Previously, -libssh2/-rtmp options assumed that OpenSSL is also enabled
  (and then failed with an error when not finding expected OpenSSL headers),
  but this isn't necessarly true, e.g. when building both libssh2 and curl
  against Schannel. This patch makes sure to only enable the OpenSSL backend

- http: set content length earlier
  
  - Make content length (ie download size) accessible to the user in the
    header callback, but only after all headers have been processed (ie
    only in the final call to the header callback).
  
  Background:
  
  For a long time the content length could be retrieved in the header
  callback via CURLINFO_CONTENT_LENGTH_DOWNLOAD_T as soon as it was parsed
  by curl.
  
  Changes were made in 8a16e54 (precedes 7.79.0) to ignore content length
  if any transfer encoding is used. A side effect of that was that
  content length was not set by libcurl until after the header callback
  was called the final time, because until all headers are processed it
  cannot be determined if content length is valid.
  
  This change keeps the same intention --all headers must be processed--
  but now the content length is available before the final call to the
  header function that indicates all headers have been processed (ie
  a blank header).

- lib: avoid fallthrough cases in switch statements
  
  Commit b5a434f7f0ee4d64857f8592eced5b9007d83620 inhibits the warning
  on implicit fallthrough cases, since the current coding of indicating
  fallthrough with comments is falling out of fashion with new compilers.
  This attempts to make the issue smaller by rewriting fallthroughs to no
  longer fallthrough, via either breaking the cases or turning switch
  statements into if statements.
  
    lib/content_encoding.c: the fallthrough codepath is simply copied
      into the case as it's a single line.
    lib/http_ntlm.c: the fallthrough case skips a state in the state-
      machine and fast-forwards to NTLMSTATE_LAST. Do this before the
      switch statement instead to set up the states that we actually
      want.
    lib/http_proxy.c: the fallthrough is just falling into exiting the
      switch statement which can be done easily enough in the case.
    lib/mime.c: switch statement rewritten as if statement.
    lib/pop3.c: the fallthrough case skips to the next state in the
      statemachine, do this explicitly instead.
    lib/urlapi.c: switch statement rewritten as if statement.
    lib/vssh/wolfssh.c: the fallthrough cases fast-forwards the state
      machine, do this by running another iteration of the switch
      statement instead.
    lib/vtls/gtls.c: switch statement rewritten as if statement.
    lib/vtls/nss.c: the fallthrough codepath is simply copied into the
      case as it's a single line. Also twiddle a comment to not be
      inside a non-brace if statement.

- scripts/copyright: .muse is .lift now
  
  And update 5 files with old copyright year range

- cmdline-opts: made the 'Added:' field mandatory
  
  Since "too old" versions are no longer included in the generated man
  page, this field is now mandatory so that it won't be forgotten and then
  not included in the documentation.
  
  Closes #7786

- curl.1: remove mentions of really old version changes
  
  To make the man page more readable, this change removes all references
  to changes in support/versions etc that happened before 7.30.0 from the
  curl.1 output file. 7.30.0 was released on Apr 12 2013. This particular
  limit is a bit arbitrary but was fairly easy to grep for.
  
  It is handled like this: the 'Added' keyword is only used in output if
  it refers to 7.30.0 or later. All occurances of "(Added in $VERSION)" in
  description will be stripped out if the mentioned $VERSION is from
  before 7.30.0. It is therefore important that the "Added in..."
  references are always written exactly like that - and on a single line,
  not split over two.
  
  This change removes about 80 version number references from curl.1, down
  to 138 from 218.

  On connection shutdown, a new TLS session ticket may arrive after the
  SSL session cache has already been destructed. In this case, the new
  SSL session cannot be added to the SSL session cache.
  
  The callers of Curl_ssl_addsessionid() need to know whether the SSL
  session has been added to the cache. If it has not been added, the
  reference counter of the SSL session must not be incremented, or memory
  used by the SSL session must be freed. This is now possible with the new

  curl to exit the loop with an error instead. It can't be converted
  because the year it would represent doesn't fit in the 'int tm_year'

- configure: make --disable-hsts work
  
  The AC_ARG_ENABLE() macro itself uses a variable called
  'enable_[option]', so when our script also used a variable with that
  name for the purpose of storing what the user wants, it also
  accidentally made it impossible to switch off the feature with
  --disable-hsts. Fix this by renaming our variable.

  Closes #7656

- opt-docs: verify man page sections + order
  
  In every libcurl option man page there are now 8 mandatory sections that
  must use the right name in the correct order and test 1173 verifies
  this. Only 14 man pages needed adjustments.
  
  The sections and the order is as follows:
  
   - NAME
   - SYNOPSIS
   - DESCRIPTION
   - PROTOCOLS
   - EXAMPLE
   - AVAILABILITY
   - RETURN VALUE
   - SEE ALSO

  Closes #7656

- opt-docs: make sure all man pages have examples
  
  Extended manpage-syntax.pl (run by test 1173) to check that every man
  page for a libcurl option has an EXAMPLE section that is more than two
  lines. Then fixed all errors it found and added examples.

  The file format for each option now features a "Example:" header that
  can provide one or more examples that get rendered appropriately in the
