- Curl_write_plain/Curl_read_plain have been eliminated. Last code use
now uses Curl_conn_send/recv so that requests use conn->send/revc
callbacks which defaults to cfilters use.
- Curl_recv_plain/Curl_send_plain have been internalized in cf-socket.c.
- USE_RECV_BEFORE_SEND_WORKAROUND (active on Windows) has been moved
into cf-socket.c. The pre_recv buffer is held at the socket filter
context. `postponed_data` structures have been removed from
`connectdata`.
- the hanger in HTTP/2 request handling was a result of read buffering
on all sends and the multi handling is not prepared for this. The
following happens:
- multi preforms on a HTTP/2 easy handle
- h2 reads and processes data
- this leads to a send of h2 data
- which receives and buffers before the send
- h2 returns
- multi selects on the socket, but no data arrives (its in the buffer already)
the workaround now receives data in a loop as long as there is something in
the buffer. The real fix would be for multi to change, so that `data_pending`
is evaluated before deciding to wait on the socket.
io_buffer, optional, in cf-socket.c, http/2 sets state.drain if lower
filter have pending data.
This io_buffer is only available/used when the
-DUSE_RECV_BEFORE_SEND_WORKAROUND is active, e.g. on Windows
configurations. It also maintains the original checks on protocol
handler being HTTP and conn->send/recv not being replaced.
The HTTP/2 (nghttp2) cfilter now sets data->state.drain when it finds
out that the "lower" filter chain has still pending data at the end of
its IO operation. This prevents the processing from becoming stalled.

Refactoring of connection setup and happy eyeballing. Move
nghttp2. ngtcp2, quiche and msh3 into connection filters.
- eyeballing cfilter that uses sub-filters for performing parallel connects
- socket cfilter for all transport types, including QUIC
- QUIC implementations in cfilter, can now participate in eyeballing
- connection setup is more dynamic in order to adapt to what filter did
really connect. Relevant to see if a SSL filter needs to be added or
if SSL has already been provided
- HTTP/3 test cases similar to HTTP/2
- multiuse of parallel transfers for HTTP/3, tested for ngtcp2 and quiche
- Fix for data attach/detach in VTLS filters that could lead to crashes
during parallel transfers.
- Eliminating setup() methods in cfilters, no longer needed.
- Improving Curl_conn_is_alive() to replace Curl_connalive() and
integrated ssl alive checks into cfilter.
- Adding CF_CNTRL_CONN_INFO_UPDATE to tell filters to update
connection into and persist it at the easy handle.
- Several more cfilter related cleanups and moves:
- stream_weigth and dependency info is now wrapped in struct
Curl_data_priority
- Curl_data_priority members depend is available in HTTP2|HTTP3
- Curl_data_priority members depend on NGHTTP2 support
- handling init/reset/cleanup of priority part of url.c
- data->state.priority same struct, but shallow copy for compares only
- PROTOPT_STREAM has been removed
- Curl_conn_is_mulitplex() now available to check on capability
- Adding query method to connection filters.
- ngtcp2+quiche: implementing query for max concurrent transfers.
- Adding is_alive and keep_alive cfilter methods. Adding DATA_SETUP event.
- setting keepalive timestamp on connect
- DATA_SETUP is called after the connection has been completely
setup (but may not connected yet) to allow filters to initialize
data members they use.
- there is no socket to be had with msh3, it is unclear how select
shall work
- manual test via "curl --http3 https://curl.se" fail with "empty
reply from server".
- Various socket/conn related cleanups:
- Curl_socket is now Curl_socket_open and in cf-socket.c
- Curl_closesocket is now Curl_socket_close and in cf-socket.c
- Curl_ssl_use has been replaced with Cur_conn_is_ssl
- Curl_conn_tcp_accepted_set has been split into
Curl_conn_tcp_listen_set and Curl_conn_tcp_accepted_set
with a clearer purpose
Closes #10141

- almost all backend calls pass the Curl_cfilter intance instead of
connectdata+sockindex
- ssl_connect_data is remove from struct connectdata and made internal
to vtls
- ssl_connect_data is allocated in the added filter, kept at cf->ctx
- added function to let a ssl filter access its ssl_primary_config and
ssl_config_data this selects the propert subfields in conn and data,
for filters added as plain or proxy
- adjusted all backends to use the changed api
- adjusted all backends to access config data via the exposed
functions, no longer using conn or data directly
cfilter renames for clear purpose:
- methods `Curl_conn_*(data, conn, sockindex)` work on the complete
filter chain at `sockindex` and connection `conn`.
- methods `Curl_cf_*(cf, ...)` work on a specific Curl_cfilter
instance.
- methods `Curl_conn_cf()` work on/with filter instances at a
connection.
- rebased and resolved some naming conflicts
- hostname validation (und session lookup) on SECONDARY use the same
name as on FIRST (again).
new debug macros and removing connectdata from function signatures where not
needed.
adapting schannel for new Curl_read_plain paramter.

- general construct/destroy in connectdata
- default implementations of callback functions
- connect: cfilters for connect and accept
- socks: cfilter for socks proxying
- http_proxy: cfilter for http proxy tunneling
- vtls: cfilters for primary and proxy ssl
- change in general handling of data/conn
- Curl_cfilter_setup() sets up filter chain based on data settings,
if none are installed by the protocol handler setup
- Curl_cfilter_connect() boot straps filters into `connected` status,
used by handlers and multi to reach further stages
- Curl_cfilter_is_connected() to check if a conn is connected,
e.g. all filters have done their work
- Curl_cfilter_get_select_socks() gets the sockets and READ/WRITE
indicators for multi select to work
- Curl_cfilter_data_pending() asks filters if the have incoming
data pending for recv
- Curl_cfilter_recv()/Curl_cfilter_send are the general callbacks
installed in conn->recv/conn->send for io handling
- Curl_cfilter_attach_data()/Curl_cfilter_detach_data() inform filters
and addition/removal of a `data` from their connection
- adding vtl functions to prevent use of Curl_ssl globals directly
in other parts of the code.

Failures clearly returned from a (SOCKS) proxy now causes this return
code. Previously the situation was not very clear as what would be
returned and when.
In addition: when this error code is returned, an application can use
CURLINFO_PROXY_ERROR to query libcurl for the detailed error, which then
returns a value from the new 'CURLproxycode' enum.

* HTTPS proxies:
An HTTPS proxy receives all transactions over an SSL/TLS connection.
Once a secure connection with the proxy is established, the user agent
uses the proxy as usual, including sending CONNECT requests to instruct
the proxy to establish a [usually secure] TCP tunnel with an origin
server. HTTPS proxies protect nearly all aspects of user-proxy
communications as opposed to HTTP proxies that receive all requests
(including CONNECT requests) in vulnerable clear text.
With HTTPS proxies, it is possible to have two concurrent _nested_
SSL/TLS sessions: the "outer" one between the user agent and the proxy
and the "inner" one between the user agent and the origin server
(through the proxy). This change adds supports for such nested sessions
as well.
A secure connection with a proxy requires its own set of the usual SSL
options (their actual descriptions differ and need polishing, see TODO):
--proxy-cacert FILE CA certificate to verify peer against
--proxy-capath DIR CA directory to verify peer against
--proxy-cert CERT[:PASSWD] Client certificate file and password
--proxy-cert-type TYPE Certificate file type (DER/PEM/ENG)
--proxy-ciphers LIST SSL ciphers to use
--proxy-crlfile FILE Get a CRL list in PEM format from the file
--proxy-insecure Allow connections to proxies with bad certs
--proxy-key KEY Private key file name
--proxy-key-type TYPE Private key file type (DER/PEM/ENG)
--proxy-pass PASS Pass phrase for the private key
--proxy-ssl-allow-beast Allow security flaw to improve interop
--proxy-sslv2 Use SSLv2
--proxy-sslv3 Use SSLv3
--proxy-tlsv1 Use TLSv1
--proxy-tlsuser USER TLS username
--proxy-tlspassword STRING TLS password
--proxy-tlsauthtype STRING TLS authentication type (default SRP)
All --proxy-foo options are independent from their --foo counterparts,
except --proxy-crlfile which defaults to --crlfile and --proxy-capath
which defaults to --capath.
Curl now also supports %{proxy_ssl_verify_result} --write-out variable,
similar to the existing %{ssl_verify_result} variable.
Supported backends: OpenSSL, GnuTLS, and NSS.
* A SOCKS proxy + HTTP/HTTPS proxy combination:
If both --socks* and --proxy options are given, Curl first connects to
the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS
proxy.
TODO: Update documentation for the new APIs and --proxy-* options.
Look for "Added in 7.XXX" marks.

This commit renames lib/setup.h to lib/curl_setup.h and
renames lib/setup_once.h to lib/curl_setup_once.h.
Removes the need and usage of a header inclusion guard foreign
to libcurl. [1]
Removes the need and presence of an alarming notice we carried
in old setup_once.h [2]
----------------------------------------
1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard
up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H,
this single inclusion guard is enough to ensure that inclusion of
lib/setup_once.h done from lib/setup.h is only done once.
Additionally lib/setup.h has always used __SETUP_ONCE_H macro to
protect inclusion of setup_once.h even after commit ec691ca3, this
was to avoid a circular header inclusion triggered when building a
c-ares enabled version with c-ares sources available which also has
a setup_once.h header. Commit ec691ca3 exposes the real nature of
__SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard
foreign to libcurl belonging to c-ares's setup_once.h
The renaming this commit does, fixes the circular header inclusion,
and as such removes the need and usage of a header inclusion guard
foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl.
2 - Due to the circular interdependency of old lib/setup_once.h and the
c-ares setup_once.h header, old file lib/setup_once.h has carried
back from 2006 up to now days an alarming and prominent notice about
the need of keeping libcurl's and c-ares's setup_once.h in sync.
Given that this commit fixes the circular interdependency, the need
and presence of mentioned notice is removed.
All mentioned interdependencies come back from now old days when
the c-ares project lived inside a curl subdirectory. This commit
removes last traces of such fact.

Stop the abuse of CURLE_FAILED_INIT as return code for things not being
init related by introducing two new return codes:
CURLE_NOT_BUILT_IN and CURLE_UNKNOWN_OPTION
CURLE_NOT_BUILT_IN replaces return code 4 that has been obsoleted for
several years. It is used for returning error when something is
attempted to be used but the feature/option was not enabled or
explictitly disabled at build-time. Getting this error mostly means that
libcurl needs to be rebuilt.
CURLE_FAILED_INIT is now saved and used strictly for init
failures. Getting this problem means something went seriously wrong,
like a resource shortage or similar.
CURLE_UNKNOWN_OPTION is the option formerly known as
CURLE_UNKNOWN_TELNET_OPTION (and the old name is still present,
separately defined to be removed in a very distant future). This error
code is meant to be used to return when an option is given to libcurl
that isn't known. This problem would mostly indicate a problem in the
program that uses libcurl.
|

|
|
|
|

In my attempts to reduce #ifdefs in code, the SOCKS functions are now
macros when libcurl is built without proxy support and therefore the FTP
code could avoid some #ifs.

CURLOPT_SOCKS5_GSSAPI_SERVICE and CURLOPT_SOCKS5_GSSAPI_NEC to allow libcurl

these.

is an inofficial PROXY4 variant that sends the hostname to the proxy instead

CURLPROXY_SOCKS4A as well.
